0.2.6-RC5 - BPDU handling fixes
Hello all,
The 0.2.6-RC5 release is available. It mainly fixes (again!) BPDU handling on the NM-16ESW switch module.
Bugfixes / Changes:
- Incorrect BPDU MAC address recognition: this solves the problem of IS-IS not establishing adjacencies through a NM-16ESW (reported on Hacki’s forum) ;
- BPDU packets tagged incorrectly on non-trunk ports ;
- Merged a patch from Thomas Pani to list VM TCP console ports (required for gDynagen).
Files:
0.2.6-RC5 binary for Linux x86 platforms
0.2.6-RC5 binary for Linux x86_64 platforms
0.2.6-RC5 binaries for Windows XP and 2000
0.2.6-RC5 source code
Chris.

So excited!
You are really the smartest man in the world,9999…Thanks,to you!
I remembered that you have told us that no QoS support in the former version,now how about it or any plan?
And in you plan,when will the version with ISDN feature be released?
Thanks again,cheers!!!!!
December 8th, 2006 at 3:52 am
Thank you very much!
December 8th, 2006 at 8:25 am
When will the layer 3 switch be supportted? such as 3560,3750.I’m expecting…Thx again!
December 8th, 2006 at 4:00 pm
Thank you ! Great!

Chris, you are the best.
As Chrismast coming soon, I am wishing you and your family have a wonderfull Chrismast and Happy New Year.
December 9th, 2006 at 6:55 am
thank you very much, you are my idol , i cann’t find other words to express my feelings about your magical works. i have learn a lot from your incredible DYNAMIPS. and you are the BEST . Chris !!
December 9th, 2006 at 9:42 am
IS-IS>
this NM module is also a layer 3 switch u can also use routed ports but not have enhanced IOS like 3550 and 3560
December 9th, 2006 at 9:49 am
When will the Vista be supported ?
Unable to find device list in Vista..We expect a new version will be supported anytime soon…
December 9th, 2006 at 1:59 pm
thanks man, although i am quite late to say this.
December 9th, 2006 at 3:22 pm
Hello,
I have very strange problem, when try to connected two instances with PA-POS-OC3 via udp socket. When I issue “no shutdown” on POS interfaces both of the instances hangs?
Any suggestions?
Thanks
December 10th, 2006 at 12:19 am
Excellent work!! Thank you Chris and Greg.
I have been following the prject for some time and have used it sucessfully for simulations.
Being a non-programmer, I have been unable to contribute to the project however, if it is of interest to anybody, I have created a live CD with the following great tools:
Dynagen 0.8.2 ( http://dynagen.sourceforge.net )
Gdynagen ( http://pani.webhop.org/gdynagen )
dynagui ( dynagui.sourceforge.net )
virtualpod to follow ( http://www.virtualpod.org )
Bochs - With this tool it is possible to start a virtual PC and connect it to a router interface.
( sample lab included )
A number of prebuilt labs are included and can be loaded using built in scripts
THe CD is based across the excellent mpentoo ( http://www.pentoo.ch ) which includes a number of network/cracking tools. The size of the CD is 400MB
Chris/Greg - If you are interested, please provide me with FTP details to upload the file to. If you think is worthwhile - I will release it to the community.
Again - thank you and carry on the great work.
December 11th, 2006 at 4:47 am
hi, Chris
I make a lab using a PA-POS-OCS ,command like this:
dynamips-026rc5.exe c7200-p-mz.123-4.T4.bin -p 1:PA-POS-OC3 -s 1:0:udp:10000:127.0.0.1:10001
after dynamips decompressed the IOS , it stops here:
1 FastEthernet interface
1 Packet over SONET interface
125K bytes of NVRAM.
4096K bytes of packet SRAM memory.
65536K bytes of ATA PCMCIA card at slot 0 (Sector size 512 bytes).
8192K bytes of Flash internal SIMM (Sector size 256K).
if I don’t use the parameter ”-s 1:0:udp:10000:127.0.0.1:10001” , it can boot nomally ,
if it needs other parameters ?
thanks for your great work and your selflessness

Prof Chris,
The fixed Dynamips is really wonderful man!
i really have no words to express it for you!
just wana ask you if there is future plan for scurity appliances such as the PIXes or ASAs. Man, that would really be a wonderful thing to have!
Thanks again and i wish you a happy new year in advance!
December 12th, 2006 at 10:54 am
Chris and Greg,
I have worked on my own topology max of 5 routers. Latest release gave me awesome experience.
I agree with Digital if we have security appliances emulated it would be good for Newbies to know about the Product and how it works and it would be helpful for guy who are going to give their exams.
I would like to say one thing here that we are bit lack in formatted document and graphical interface. I think Boson is very famous because of their Network designer tool if we have such a tool for our Dynamips every body can use our software at top of the world.
I have red in the forum that to emulate 3550 or 3560 you need PowerPC to program those hardware to be emulated is it so.
also if we have separate model for switching like 3550-XX.3560-XX
Wish to have from you Chris
Cheers

Hello
Thank you for these efforts so far
I tested the latest version running 11 router instance and using the ghost feature
It is running smooth but the only issue is the ping delay
BGP and ospf neighbours time out and ping has delay of upto 2 seconds
I was hoping you could emulate a verly low end device like the 2600 series that do not take too much from the memory or the processor
Iam currently using the 3620 sereies
Thanks and good luck
December 12th, 2006 at 10:01 pm
Chris and Greg,
I use the following topology and try to ping R2 from R1. The ping works, but when I run ‘show interfaces fastEthernet 1/1’ on SW1, the packet input and the packet output are all 0. I think this is a bug.
R1(f0/0)——(f1/1)SW1(f1/2)——(f0/0)R2
VLAN 10: (f1/1 and f1/2)
SW1#show interfaces fastEthernet 1/1
FastEthernet1/1 is up, line protocol is up
……
5 minute input rate 0 bits/sec, 0 packets/sec
5 minute output rate 0 bits/sec, 0 packets/sec
0 packets input, 0 bytes, 0 no buffer
Received 0 broadcasts, 0 runts, 0 giants, 0 throttles
0 input errors, 0 CRC, 0 frame, 0 overrun, 0 ignored
0 input packets with dribble condition detected
0 packets output, 0 bytes, 0 underruns
……
Thank you,
Frank

Hi all.
First of all big big thanks to Chris and Greg!
I am using only dynamips for now, because i have no time explore dynagen for now. I hope the next year will be less busy for me and i will learn it.
I think i have discovered a problem with the switch module on 3660 for now! Here are the configs:
Router1:
dynamips –idle-pc=0×6070c4b8 -T 10100 -t npe-400 -M std -p 0:C7200-IO-FE -p 1:PA-FE-TX -s 0:0:udp:10000:localhost:20010 -s 1:0:gen_eth:”\Device\NPF_{D4BAD741-7953-484D-ADC1-2053C732FACE}” Image.bin
ROuter2 (used as a basic switch):
dynamips -P 3600 -T 20100 –idle-pc=0×604291fc -t 3660 -p 0:Leopard-2FE -p 1:NM-16ESW -s 0:0:null -s 0:1:null -s 1:0:udp:20010:localhost:10000 -s 1:1:gen_eth:”\Device\NPF_{5237F7DA-7EE3-4D33-83F0-BED359BEB706}” -s 1:2:gen_eth:”\Device\NPF_{DB126BDF-662A-4615-B20D-F58B4ED81B36}” -s 1:3:null -s 1:4:null -s 1:5:null -s 1:6:null -s 1:7:null -s 1:8:null -s 1:9:null -s 1:10:null -s 1:11:null -s 1:12:null -s 1:13:null -s 1:14:null -s 1:15:null Image.bin
As you can see the topology is as follows:
PC1———-Switch——-Router——–Server
|
PS2———–|
PC1 and PC2 are configured in different vlans, they are connected to ports fa 1/1 and fa1/2 to the switch (router2)
The router is configured for inter-vlan routing with subinterfaces to the switch. The server is connected to second fa port to the router!
What i have achieved is that when the pcs are connected to a port of the switching module, the have no connectivity to the switch and also the router!
After a lot of plays and so on, i only achieved arp connectivity-i manage to prove that arp requests and replies are sent and recieved from both sides, except when the router is asking for the mac of the PCs. Then the arp messages are filltered on the switch side and are not recieved by the PCs!
THe “real” interfaces are vmware ones-VMNet1, VMNet2 and VMNet3!
I must say that there is no problem when a PC is attached to a router port(other than the switching module), but when they are attached to the switching there is no connectivity.
If you need more info, please mail me. I will posted here and/or reply with e-mail-just as you wish!
Have a nice day/evening, month , year century!
Thank you very much aggain!

Hello!
I have a question regarding the ghost option. Indeed it saves ram, but my page file goes way high. I mean, the more routers I add, the bigger the page file gets. Is this normal behaviour? Can i prevent this from happening? I am using win XP, dynamips 0.2.6-RC5 and dynagen 0.8.2. I tried ghosting both with memory map on and off, same thing. I feel it works better without memory mapping and no ghosting than it works without memory mapping and ghosting. In other words i feel like ghosting isn’t a plus on my system. Can someone clear this out for me?
Thanks!
December 19th, 2006 at 2:11 am
Prof Chris,
I remembered that you have told us that no QoS support in the former version,now how about it or any plan?
when will the version with ISDN and PIXes feature be released?
Thanks and I wish you a happy new year in advance!
December 21st, 2006 at 12:37 pm
Please guide me on installing this software on Windows XP Professional.
Thanks
December 21st, 2006 at 1:24 pm
reza>
1. install “Winpcap” look it on google
2. get a Cisco IOS image for a supported Chasis like the 7200
3.extract chris binary on a folder and put the image in it
4. go to command prompt and type : c:> dynamips-wxp.exe [ios image]
this is a good start for Dynamips
Dynagen is easier though try to use it
December 21st, 2006 at 9:10 pm
Chris,
I don’t see your post on this release, are you busy in enhancing the Dynamips?
May I know what would be the feature is going to get add in the next release?
Thanks.
December 22nd, 2006 at 2:39 pm
Chris,
Is there any way to be able to sniff via Ethereal/Wireshark a traffic that is exchanged between Ethernet ports of two virtual instances? Sniffing via SPAN on NM-16ESW only sniffs what real SPAN can do, so only L3+ information, but if I want to sniff for example MPLS packets, they’re not visible.
Somethink like capturing traffic exchanged between two TCP ports that instances are communicating with, and either exporting it to virtual interface (loopback) or directly to named file on file system would be great.
December 23rd, 2006 at 10:15 am
Recent Debian packages for dynamips and dynagen are available at gpl.code.de.
Include the following lines in /etc/apt/sources.list:

Hi Chris ,
I wanted t know that can we run the dynamips hypervisor server as a service running in Windows Server background as other services run.
basically i want that there is no windows for the server running….becoz the server i am using is used by other people also .. so..i dont want anyone else to close the window..

December 28th, 2006 at 3:45 pm
Vikas,
You could try using srvany.exe. See http://support.microsoft.com/kb/137890 .
December 29th, 2006 at 2:24 am
ral_fan,
I’ve added a file capture mechanism for the dynamips. Currently I have an issue left that it times out with dynagen when the trace will be disabled. As soon as I’ve solved this I’ll post it.
regards
Oliver
December 29th, 2006 at 7:25 am
Hi Greg ,
I tried using srvany.. but it didnt worked .. it gave an error that ” the application does not respond in an desired fashion”.
And as it demanded for the path of .exe file to be run as daemon.. we are having a .bat file which again tries to open a window
December 29th, 2006 at 8:28 am
hi chris and greg happy new year to both of u guys.
hey buddies. is there a surprise from u guys abt dynamips in the new year. what new things we could see in the dynamips in the new year.

Chris is doing the switch emulator. I am so exciting about it.
Our dreams come true, our dream come true.

Other than that, HAPPY NEW YEAR!!!
December 30th, 2006 at 8:39 am
Hi Greg ..
pointing srvany to dynamips.exe is nott working as the full command to use the hypervisor mode is “dynamips.exe -H 7200″
i am now experimenting with FireDaemon as suggested by Nula..
Can u plz try this on u r PC and tell my the way to do that..

This is great news of this year that switches will be emulated, then where will these “Rent a Rack” will go, i wonder.
Thanks a zillion
January 1st, 2007 at 3:39 am
great achievement this tool is, bravo Chris and Greg and others that contribute to this project !!
January 1st, 2007 at 12:42 pm
hi chris happy new year to u and greg also. but this amazing creation of dynamips. it;s really great to hear that u are now working on to emulate switches that;s great.
chris yes i can take pictures of the the entire switch board, processor the chipset used. i got both the 3550 24 port 10/100 switch and 24 port 10/100 3560 switch.
tell me u want pictures of which one 3550 or 3560.
waiting for ur reply. i can send them soon as possible.

January 2nd, 2007 at 1:40 am
Awful design and an extreme idea. Now we dont need thousands of dollars to spend for advanced level cisco stuffs.
Integrating c3640 image with my laptops ethernet interfaces is very interesting. Surely, it will not give performance of real cisco stuff but it will emulate what a real cisco router does.
if you have problems pinging other dynagen device (your other dynamips server installed pc) change mac address of interface on cisco console mac-address 0000.0000.0000 is default at start-up and other devices mac-address is the same .
Zebra ( Quagga) and Dynamips-server are my real stuff
.
January 2nd, 2007 at 5:15 am
Hello
Happy new Year all of you brothers
good news from Chris that he is reading the powerpc now to emulate the 3550 & 2560 switches.
i think based on the new Cisco news that they use the 3560 + 3550 in the CCIE exam, so in my own openion its worth the emulation of 3560 switches, but we dont mind any magic comes out from ur hand Chris.
i thought 2007 would be great and here we go, Chris is the mode to to the 3560 switches ………. oh lalalalala
keep up the good job Chris and may our dreams comes true one day with the 3560 switch to beat the CCIE with ur tools.
best regards
January 2nd, 2007 at 7:30 am
hi chris can u tell us u are trying for the emulation of 3550 switch or 3560 switch.
i guess powerpc is for both the switches right. if possible try for the 3560 switches . i guess there has been not much hardware changes in 3560.
chris waiting for ur reply regarding the snapshots of the chipset used in 3560 .
regards
sebastan
January 2nd, 2007 at 11:01 am
Hi Sebastan,
Why don’t you give him both? 3550 and 3560 snapshots…
Thank you
January 2nd, 2007 at 1:21 pm
sebastan> There is a PowerPC 405 in these switches. I don’t know the hardware differences between 3550 and 3560, so if you can take pictures for both models, it would be perfect. Thanks.
MyOwn> “This is great news of this year that switches will be emulated”. If you read carefully, you will see that I never wrote this. I said I will try, but there is no warranty that I can emulate something if the ASICs are too complex.
January 3rd, 2007 at 5:04 am
Prof Chris,
I guess everyone knows what you’ve previously said about “trying” to emulate the switches but for some reasons people get really excited about it and take it for granted!
to tell u the truth, i have faith that you can do it! Everytime i use the Dyanamips and get something done for my CCIE i remember how powerful ur brain is! 
If the ASICs are too complex and can NEVER be done then it doesn’t mean that Dynamips losses its value! It’s really something i would remember you for and appreciate for the rest of my life (as long as Cisco remains alive! :)) Thank you for your priceless effort!
January 3rd, 2007 at 5:31 am
Heya,
I’d like to get dynamips compiled under OSX 10.4 with Xcode if possible. Can anyone point me in the right direction? Has anyone done it before? I know i need libpcap and libelf, but i’m not really a developer, just a sysadmin. I dont want to go buggering up my system by dicking around.
failing that i guess i can just run the linux version in a Parallels/VMware VM
cheers,
Daniel
January 3rd, 2007 at 6:47 am
hi Chris,
When you said, You will try, then mostly what i can understand is that, it will be here some day, as trying is first step to “accomplish”. I will repeat again that we will have “switch” one day sooner or later for dynamips and this is my trust in your brain.
These days what i am thinking is that, Linus Torvalds have revolutionized the concept of “OS” and Chris have re-invented the “Black Art of Routing”. Both guys are great and some what equal in their services. ( Seriously).

hi Chris> i have just started a page for Christophe Fillot at wikipedia, http://en.wikipedia.org/wiki/Christophe_Fillot
If found time then please provide your biography at the page to populate it.
Hope it will help to keep “records” clean.
Best Regards,
January 3rd, 2007 at 10:09 am
hi chris thanks for ur reply buddy. just give me 2 days time i will send snapshots of both the switches i have. hey chris pls tell me where should i send u the snaps.
chris also pls tell me what do u want exactly in the pic. i mean the processor, the board, the chipset or the complete thing. cause u will have to zoom in the picture for reading the details.
so if u can tell me what components should i focus on while taking the picture.
waiting for ur reply.
regards

Daniel,
I compiled on osx 10.4, I couldn’t get past the libpcap either so I disabled it in the make file, I’m not sure why its needed unless its for using the physical interface to physical interface. I use dynamips isolated and they talk to each other too. I also use iTerm as terminal is cr?p.
BTW there is nothing like using your macbook pro in a coffee shop configuring routers….. ahhhh.
Chris,
I’d like to send some photo’s and the IP address of the 3750 switch module for the 2800/3800 routers. I can send you telnet details too.

hi,Chris
i think there is a bug u don’t know:
1.the default config of duplex mode and speed of the fastethernet port should be both auto,while on 3660 emulator the default value is half-duplex and 100m/s through command ’sh int’,and both auto through ’sh run’.but a NM-16ESW port is correct on this point.that makes duplex mismatch when a router’s ethernet port is connected with the NM-16ESW ethernet port.
2.furthermore,the ethernet port on router cann’t be set to 10M/s although it accept the command ’speed 10′ and we can see ’speed 10′ through ’sh run’,but from ’sh int’ the port is still 100M.
can u fix it in new ver?
thank u very much!
January 3rd, 2007 at 1:30 pm
alexnew> I don’t think it is a big issue by asking Chris fixing this error as you said “a default”. You can manually fix it by do a command duplex full under the interface mode. For the 10M/s, just adjust the command duplex half.
Do i misunderstand something ?

January 3rd, 2007 at 3:54 pm
Hi Chris,
Frist, thank you for all the good work.
When I was trying stuff in 3620, and I noticed an error
% Error! No serial number found for this platform.
and I am using IOS c3620-ik9o3s6-mz.123-21.BIN
It seems work all right, but I am not sure if this will affect the MAC address of those switches and VTP election.
January 3rd, 2007 at 4:45 pm
Chris>
Happy new year!
I was asking again if it would be possible that dynamips can support old IOS versions
I know you fixed this for me before in the prevoius versions
I would be more than glad you could do this for the new versions too for the other Chasis like the 3600 series
Thanks
January 3rd, 2007 at 6:46 pm
hello there, it seems i’m facing the same issue as alexnew does, after setting
up 3 3620 routers and a 3660 i’m getting dupplex mismatches, no problem at
this point, but after i issue the “full-duplex” or “duplex full” command on the
3620’s the interface is still in the “Half-duplex” mode ;

Rx(config-if)#dup full
Problem will go away.

Hi Chris,
Happy New Year!!!
I am ready to plunge in your development flow.
I start picking up few things to get the coding started from your past source codes (pardon me for some silly questions that I asked and will be asked).
I have grabbed some CatOS with me to test on some 3550/3560 sims
Which part could I help you to test it with???
Cheers,
Dwi
January 4th, 2007 at 11:13 am
Chris,
Here is the difference between 3550 and 3560 in a nutshell:
http://www.cisco.com/application/pdf/en/us/guest/products/ps6406/c1031/cdccont_0900aecd8057a2c6.pdf
basically, the difference is mainly from IOS, the hardware block should be the same.
I will have a look at the 3560 board soon, can’t take picture though ‘coz my digicam is not with me at the moment
I will inform you when the 3560 pics are ready
January 4th, 2007 at 4:42 pm
that is good news, that DWI is also interested and doing some work on it.
Thanks for all of your dedication to this project.

Guys, who can spend some time and share with us some various .net files with wrong cfg’s for routers involved into .net file scenario?
Its a good idea to train in troubleshooting this way
icq me about this question #212228

January 4th, 2007 at 7:19 pm
I mean links to projects related to dynamips project.
January 5th, 2007 at 12:59 am
Most projects have a link on the wiki page for Dynamips (www.ipflow.utc.fr/index.php/Cisco_7200_Simulator). When Hacki’s forums come back up, I know there’s a sticky post on this in one of the forums.
January 5th, 2007 at 8:18 am
Hi Chris and All,
I have some bandwidth quota left that is seldom in used from my internet links.
If you like, I could help mirror Hacki’s content for the dynamips as the mirror site.

I just posted version 0.8.3 of Dynagen.
This is a really minor update. The only feature is the addition of a “–notelnet” command line option that will make integration with gDynagen easier (http://gdynagen.sourceforge.net). That and bundling Dynamips 0.2.6-RC5.

Jeffsiew> Yes, summary-address works. I tested a lots on IEWB
January 10th, 2007 at 3:43 pm
To decompress an IOS image, rename the extension from .BIN to .ZIP. The file should unzip just fine with your choice of ZIP programs. You will have to rename the file produced, since it is natively stored as C7200-IS.BIN (or something similar).
January 10th, 2007 at 9:25 pm
Man, no forums is killing me… I apoligize, but I can’t find a another place where dynamips folks are actively posting.
Anyway, I’m trying to start dynamips from an init script. I don’t see any daemonize options. Has anybody figured out a way to fork the dynamips process out of a standard init script and without breaking out of the script altogether? I’ve tried “&”, setsid, nohup, even screen -d -m. All of these mothods break out of the init script. I need dynamips to fork and return 0 so I can put proper controls and montoring in place.
Thanks

Hi All,
What is the above metioned step aboit. Is ita about backgrounding dynamips ?
January 12th, 2007 at 8:54 am
Vikas:
Its about how to start dynamips with GNU screen, as far as I can see. With scren’s detach functionality, you have dynamips running in a persistent manner. Some time ago I posted a small howto for that on hacki’s, but its down atm.
ddy:
I was able to adopt a standard debian init.d skeleton file to get dynamips daemonized with the usual start-stop-daemon control method. YMMV, depending on the distribution you use.
@all:
I’m not sure what happened to hacki.at and I hope that the forum comes back. As a temorarily replacement and, when the forum is back, as an addon, I wonder if a mailinglist as a support channel you guys would like to use.
Furthermore, an IRC channel can be great for solving issues fast. As far as I can see, somebody already registered #dynamips on freenode (but its empty atm).
What do you think?

Many thanks for your invaluable works !!!! hope the hacki forum will be back soon..
January 13th, 2007 at 4:40 am
wangzb, There is no BUG in dynamips pertaining the IPv6 with OSPFv3. I have been doing lots of complex topolgies with OSPFv3 and everything is working perfect! Since i don’t know what you’re trying to to do i can’t figure out what’s wrong but if u look carefully you’ll find the IPv6 address “2000:db8:0:aa01::1″ cannot be found attached to any of your router!
My guess is to change the ping to 2001:db8:0:aa01::1 not 2000:db8:0:aa01::1
January 13th, 2007 at 7:35 am
wangzb: I think you’ll find that R2 hasn’t learned any RIPng routes from R1. Fix this and you should then be able to ping 2001:db8:0:aa01::1. You will also need to set the link-local address for S1/1 on R2. You will also need to set the Router ID manually on R2/R3, since you don’t have any IPv4 addresses for OSPFv3 to use.

Hello,
I guess i”ll just be repeating what the rest of the guys have said, but i cant help it. I have to say this.
!! Dynamips/DynaGen is just Great -really cool !!
Came across this really superb stuff just yesterday and now i already have 4 3660 routers running on my humble 512MB Intel centrino 1.6 Ghz
i am planning to get a new desktop/laptop for a full fledged lab topology
Any pointers on the hardware config , Intel DuoCore or AMD Turion or a normal Pentium 4 with HT technology?
any pointers will be really appreciated
Thanks again , esp to Chris and Greg
Cheers

Hi Chris,
I have a problem with connecting dynamips to UML hosts using vde (uml_switch/vde_switch).
- first I create a control sock:
uml_switch -unix foo -daemon
- then I start dynamips:
dynamips -P 3600 -t 3620 -r 64 -p 1:NM-1FE-TX -s 1:0:vde:foo:bas /opt/images/c3620-ik9o3s6-mz.123-17a.image
and just after I set up fa1/0 ip address and do ‘no shut’ I receive (from uml_switch):
————
Unknown connection for packet, shouldn’t happen.
send_sock sending to fd 4 No such file or directory
Unknown connection for packet, shouldn’t happen.
unknown Addr: cc:00:7e:9c:00:10 from port UNKNOWN
send_sock sending to fd 4 No such file or directory
Unknown connection for packet, shouldn’t happen.
unknown Addr: cc:00:7e:9c:00:10 from port UNKNOWN
send_sock sending to fd 4 No such file or directory
————-
When I start UML host I receive:
——-
New connection
Addr: fe:fd:00:00:02:01 New port 6
——-
I don’t have communication between dynamips and UML host!
I have also tried vde_switch and -hub option -> all the same (except that vde_switch doesn’t show any messages).
Am I doing something wrong?
Regards
Ern

January 13th, 2007 at 2:29 pm
I was wondering if it is possible to get SSH working from a client like putty or securecrt. I got SSH working from router to router using the integrated ssh client in the ios.
I think part of the problem is not knowing which port/ip address to use since the router instances all use the same address (localhost) and only have a port listed for the console interface in theh hypervisor.
I’m trying to get experience using ssh clients, so has anybody successfully done this?
Thanks!
January 13th, 2007 at 5:24 pm
Silentbob:
you can bind all your routers with an additional router interface to an interface on your host (ethernet, for example, loopback should work too) with the gen_eth netio connector.
It is described in the dynagen tutorial:
http://dyna-gen.sourceforge.net/tutorial.htm#_Toc151700444
With this, they form a dedicated network - comparable to a management network you would setup in real life.
Assign each router an ip address in this network and enable ssh on the routers.
Now you can connect to each router with you favorite ssh client by connecting to the IP address you assigned earlier.

wangzb: You’ve got two problems. First, those configs without an Ethernet adapter will result in duplicate link-local addresses. Adding an NM-1FE-TX brought all the interfacesa and routes up for me. Without resolving the duplicate link-locals, nothing worked, even neighbor discovery.
Second, an extended ping using the Loop0 on either R1 or R3 as the source worked, but execute the ping ipv6 that you listed didn’t. So I added to R2:
ipv6 router ospf 1
redistribute connected metric 1000
!
ipv6 router rip wang1
redistribute connected metric 1
This ensured that both R1 and R3 received the routes for the Serial links as well, which prevents the ICMP from returning. This is one way to fix the problem, but there are many others.
I suggest if this doesn’t work for you, that you post your .NET file and router configs to a new forum topic on the temp forums.

When i telnet to my TerminalServer router and assign ctrl+shift+6 + x in the first time for R1 or R2, i dont have any problem at all. However, if try to access R1 again ( second time), i got a problem, my TerminalServer just keep stay there and didn’t do anything.
Here is the result

Hi,
There have been a couple of requests for a method to sniff packets between virtual routers.
Method i have used that works.
Sniffer: = Etherreal
Windows XP (sorry i use a mac too, but don;t know how to on mac)
Create two MSLOOP back interfaces, these don’t need to be binded to IP.
Bridge these together using the right click ” add to bridge” option.
In dynagen, link the router interfaces to the MSLOOPback interfaces, using the network device list to get the right mappings.
Run etherreal, capturing on the virtual bridge interface.
Doing this i can see MPLS headers etc.

Excellent work!! Thank you Chris and Greg.
I have been following the prject for some time and have used it sucessfully for simulations.
Being a non-programmer, I have been unable to contribute to the project however, if it is of interest to anybody, I have created a live CD with the following great tools:
Dynagen 0.8.2 ( http://dynagen.sourceforge.net )
Gdynagen ( http://pani.webhop.org/gdynagen )
dynagui ( dynagui.sourceforge.net )
virtualpod to follow ( http://www.virtualpod.org )
Bochs - With this tool it is possible to start a virtual PC and connect it to a router interface.
( sample lab included )
A number of prebuilt labs are included and can be loaded using built in scripts
THe CD is based across the excellent mpentoo ( http://www.pentoo.ch ) which includes a number of network/cracking tools. The size of the CD is 400MB
Chris/Greg - If you are interested, please provide me with FTP details to upload the file to. If you think is worthwhile - I will release it to the community.
Again - thank you and carry on the great work.

Hi Guys,
http://amuware.com isn’t my product, I just found it on the net. This tool is for generating commands for starting dynamips from command line. You can design your topology on the screen and after that tool will generate commands for command line. You can make a account for free and with account you can save you topologies.
January 18th, 2007 at 5:49 pm
I think it would be better to automatically generate dynagen config files, instead of dynamips command lines.
January 19th, 2007 at 12:07 pm
like a front-end for a front-end tool ? :)) , it seems amuware’s target it’s dynamips , it’s just an alternative for dynagen or dynamipsGUI or other front-end tool out there
January 19th, 2007 at 1:50 pm
Hello freddy,
Apologies for the delayed response.
You will need a linux kernel that supports IP aliases ( most modern linux distros do ).
With IP alias with one ethernet card, say eth0, you can
ifconfig eth0:0 x.x.x.x
This creates a new ‘interface’ eth0:0 with IP address x.x.x.x
Boch can bind to this interface without issues however qemu has issues . interface eth0:0 can then be used with dynagen as any normal nic.
Multiple interfaces can be created using:
ifconfig eth0:1 ….
ifconfig eth0:2 …etc
Hope this helps. If you require, I can email just the custom scripts for boch.
Ismail.

there are idlepc codes of my CPU…
My config file i using on other computer with AMD64 3000+ and RAM1G, but the result was beter then now. I worked with 11 routers on AMD, but with Core 2 Duo i can start only 5 ((((
The utilisation of CPU 51% with one 3620 router.

hi guys,
I am have difficilties setting Ghost_ram feature in dynamip.
i have tried the sugested ways.. but still dynamips consume alot of ram in my computer.
i use the same ios. for 5 router.
please……… advice me…..
January 22nd, 2007 at 3:44 pm
dindra,
Have you seen this post on ghost ios & memory utilization: http://7200emu.hacki.at/viewtopic.php?t=364 ? The examples are for Windows, but the same principles apply to Linux.
January 22nd, 2007 at 4:07 pm
Shujha: That boot image is not the actual IOS feature-set image (is my understanding, asking a pal here who is much more familiar with actual 7200’s). This will boot up the router, but gives you little or no useful functionality by itself (similar to the ROMMON mode, which is analogous to the BIOS your computer has). In general, if you are not at a ‘router(config)#’ interface, then you aren’t in configuration-mode.
Also, for future reference, if ‘ip routing’ is not present in your router config (or ‘no ip routing’ IS present), then you won’t be able to route.
January 23rd, 2007 at 4:33 pm
Thanks Ismail, actually I can do the same using MS loopback Interfaces, but I want to try Boch. Then if you can send me out some of this Image it will be nice

Hi Chris,
I have a problem, I try (c3640, c7200) to copy a file 25MB from tftp: to flash: but file smaller 16MB that ok, other can’t - how to fix it? - thanks
Truong
January 24th, 2007 at 3:39 pm
You can use either Disk0: or Disk1:, which are 64MB by default but can be adjusted in your .NET file.
January 24th, 2007 at 5:46 pm
I saw some cisco document said that TFTP has a limitation of maximum file size at 16M. However, I haven’t found this problem myself. TFTP usually work even for file larger than 16M
January 25th, 2007 at 5:21 am
That right rujipars, I installed another tftp server (3CDeamon). Thanks
January 25th, 2007 at 5:30 am
Hi Chris,
when i use “show version” command. I saw this line:
…..
System image file is “tftp://255.255.255.255/unknown”
…..
what is it?
January 25th, 2007 at 10:26 am
Hi guys,
I added support for serial and ATM interfaces into dynalab tool at http://amuware.com (PA-4T+, PA-A1). Now it’s possible to create more complex lab topologies scripts. Finally I plan to support all the hardware the dynamips is capable to run in that tool. Please let me now if you find any bugs so I will fix it.
Adrian
January 25th, 2007 at 11:29 am
I almost forget, the tool supports multilink feature in this release also. Now it’s possible to interconnect two routers with several lines (same or different types). It is not displayed correctly when there are several lines between devices as the labels are overlayed, but the generated script is correct.
Adrian
January 25th, 2007 at 2:03 pm
Hi Adrian ,
The tool you have developed is really nice.
I just wanted to ask you that can you provide this sofware
as standalone package so as we will be able to us it as offline also.
Kind Regards
Vikas
January 25th, 2007 at 3:24 pm
Hi Vikas,
I’m working on downloadable standalone package, will be available soon
Kind Regards, Adrian
January 26th, 2007 at 12:06 pm
I would like to know what the plans are for Dynamips/Dynagen to support the newer Etherswitch Modules such as NME-16ES-1G etc.
Since these would provide the required L3 functionality due to running a seperate 3750 IOS image.
Regards
January 26th, 2007 at 12:30 pm
Hi Adrian ,
I am amazzed and thanks a lot…..
Waiting eagerly….
January 27th, 2007 at 12:12 am
Hello!
I’ve look through all blog but not found any solutuion for problem with high CPU load when we use NM-16ESW in 3600 routers.
I’ve tested about 4 different kinde IOS for 3640 router and about 3 different idle-pc value for each IOS. But I’ve not obtain less than 30% CPU (2.5GH) with two instance.
Does any body know how to solve this problem?

chris is trying to build 3550 and 3560 so there is no need for this module
January 28th, 2007 at 7:54 pm
Hi everyone,
Ultimately my waiting time is now over may i know where is chris chris chris are you there any new value added feature
last time you went and came with switching function this time ?
thank
greg can you please answer if chris is not around us
January 29th, 2007 at 12:11 am
Hi,
I found your blog via google by accident and have to admit that youve a really interesting blog
Just saved your feed in my reader, have a nice day
January 29th, 2007 at 7:13 am
Where is the new version??
January 29th, 2007 at 9:42 am
Reza> Where is your valuable contribution ?
January 29th, 2007 at 11:13 am
To chris,
Thinks from the bright side, that means more and more people are using your software and awaiting update. So, that’s good right? =) take it easy
When thing come for free, it’s actually pretty often that make people generate a wrong concept which exactly what Reza is having.
Again, alot of people out here are being benefited by the softwares from you, greg and other team members. Keep up the good work!
January 29th, 2007 at 11:24 am
Reza> Be more polite. These guys are working hard day in and day out to provide the students of CISCO a valuable tool. We, including myself do really appreciate what they are doing because if they wanted to they could have decided to make the software a fully commercial high priced product.
January 29th, 2007 at 12:10 pm
Cake> Moreover, the software is not just for free, it’s GPL’d which means much more.
Reza> I mean no harm, but I think you should apologize to Chris…
January 29th, 2007 at 1:46 pm
jp is right man. reza u people u are expecting a lot. dynamips is not bread and butter of greg and chris, they have their own job to do.
in the free time they have devoted to dynamips and i think everyone in this blog should appreciate that.
January 30th, 2007 at 6:55 am
Yes, I am very sorry. I wanted to say that, where is the new version that has resolved very issues that other users and me can use it without any problem.
I thank you and to many others that help to this project to grow.
Thanks a lot my friends.
January 30th, 2007 at 8:44 am
Reza,
dont talk here and there we know what did u mean 
January 30th, 2007 at 7:51 pm
Hi Chris and Greg
First of all I would like to thank you for your offer. You have provided us a perfect preparation-exam tool.
I’m currently preparing for my CCIE R&S lab exam
and I’m thinking to buy a new desktop pc in order to simulate the labs from
workbooks (like IEWB). Do you believe that an Intel Core-Duo with 2GB RAM it could be enough for a topology of 13 devices?
I’m currently using a Centrino Toshiba laptop with 1.5 processor and 1.3GB RAM and I can load and configure (with OSPF and BGP) up to 4 routers using WinXP. I did the same using Suse10.2 the same pc but the process utilization was about 20-30% higher.

Actually, I understand everyone’s eager anticipation - it is like watching a daredevil perform more amazing feats each time: ‘What comes next?”
In Reza’s defense, I suspect that either there is an interpretation difference, or else he might’ve attempted to keep his post concise.
It seems that Chris understands that, and I am certainly impressed by Chris’ good humor and lack of complaints about the pressures in any aspect of his life (either from us or from his employers for unrelated projects).
Anyway, since I was just trolling by anyway, yet again I offer my respectful congratulations and thanks for everything since over a year ago, Chris.

Mark is correct. He made a very good point. I come here, at least 3-5 times a day, just to see is there some thing “New”. Although i know that tech information is available on hacki forums, which i visit more than this. It is just human nature; need more and more. I remember the days of boson and every one was “just” happy. Now with “Dyanmite”, every one need more. Some are so eager that they ask and most of us just press F5 again and again that may ………
Hope is my best Friend.

Hi all,
now the 3640, 3725, 3745, 2691, virtual Switch and Bridge are supported at http://amuware.com It’s possible to define switch port access vlan or dot1Q native vlan for trunk, the netio.net file for each switch/bridge is generated with script.

Chris/Greg……………..
Needles to say a million times ‘’THANK YOU’’, you have done such great work and saved us loads $, I am optimistic that in time some how we will be able to emulate the most needed 35xx’s.
I am sure this was suggested but I will be more than happy to donate some bucks, to help in your development. Many like me are so exited at the prospect you have offered us we just don’t know where to stop.
February 10th, 2007 at 3:18 am
any update for 3550?Thanks !
February 10th, 2007 at 5:57 am
However it is hard to implement (but not for you ! ) we wait for basic isdn support, new improvements on catalyst module are impressive too, if isdn support made or not there will be no alternative for this efficient cisco training utulity, legal and freely distributed. User paid softwares like B… donot perform good as real IOS and like a toy when comparing dynamips project.
Maybe windows gui interface of dynamips will be released one day, drawing a map and operating this map sounds incredible
.
Thanks again for your great ideas,
February 10th, 2007 at 8:08 am
Good Work Adrian
Your tool os very useful and saves me alot of time
Please help me i could not find the “netio1.net” file. It was not generated with the script
The saves LABs feature looks very promising
I suggest also adding a shared Labs where i can see the Labs of the others
Thanks
February 10th, 2007 at 6:25 pm
Hi Skipe, Aly,
Skipe: I’m working on a standalone version, but priority is to finish this web aplication because I’m almost done and than convert it into standalone aplication.
Aly: Switch is represented as a separate instance (for example as a router number 3) and netio1.net is generated as apendix at the end of line after image.bin &. Of course you can use another instance to run virtual switch, not start separate instance of dynamips for that purpose.

Trevor> no, this project is still alive, a new release should come soon. I’m just a bit tired of people asking for 3550/3560/whatever whereas they don’t contribute at all.

Hi all,

Man, wish I could offer some contribution of a technical nature, but in general the only ‘programming’ language I know is PERL. However, if you need me to whip up some testing scripts or to test features, or research how a particular technology is supposed to work, please feel free to add my email to your distribution list and I’ll do what I can. I haven’t been the most active in this community, esp. lately, but I am ramping up as soon as I have the equipment delivered/configured ((to simulate my virtual network, house virtual servers, etc.) for my own CCIE (SP or R&S - not sure which I will start with) lab.
