FAQ
From IPFlow Netflow Collector
[edit]
What are "protocols.txt" and "services.txt" missing files and how to get them ?
If you get these messages when you run IPFlow:
serv_mgr: unable to open file './protocols.txt' (No such file or directory) serv_mgr: unable to open file './services.txt' (No such file or directory)
Use the following commands:
ipflow export_protocols > protocols.txt ipflow export_services > services.txt
By default, IPFlow searches these files in the current directory. If you want to use a specific directory, use the "-C <path>" argument on the command line.
These files are used to determine the protocol name ("tcp", "udp", ...) from the protocol number received in Netflow datagrams, and the IP service from the source and destination ports. For example, if source or destination port is 23 and protocol is TCP, the service is "telnet".
