Hi ,

1) What is the o/p of

#echo $TMOUT

2) Do you have any setting in firewall for idle connection time out ?

hi patti,

That may be an IP conflict, are you sure that your IP that you use for this server is unique

Hi Pasquale
Your problem:
- Check if you have reverse DNS lookup to your host
- Check if icmp packages is allowed through the firewall
... and I believe you can avoid these drops :)

I strongly recommend that you start using ssh instead of telnet... You mention that it's behind a firewall... and then you should be aware that telnet is not encrypting your communication - and can therefore be exposed by someone seeing your login credentials...

There is several methods to sort out Console access in secure ways and that seems to be the only reason for using telnet...

I must agree with Tor-Arne and suggest you use ssh. Telnet is very insecure and should be shutdown. Being behind a firewall is only partial security, it slows the bad guys down, it doesn't stop them. Downloading and running Bastille can help you do this, and a few other things.
