Hi,
how to know telnet version on my Linux server ?
Many thanks.

$ rpm -qa | grep telnet
telnet-0.17-31.EL4.3

and if the server is not using a redhat-based distribution ?

do you have tried telnet -v or telnet --version ?

if your box is debian based, try the following:
dpkg -l | grep telnet

the -version options did not work...
