Telnet sessions disconnected on Linux 6.2 server

[Preet Dhillon]

My telnet connections to my Red Hat Linux 6.2 server terminate at random and without warning. When I attempt to reconnect using telnet, I see the following message :

Please type [Return] two times, to initialize telnet configuration
For HELP type "?"

I hit enter twice as it asks but do not get a login prompt. If I retry after a few minutes I get the login prompt as normal.

Does anyone know what is causing this ?

Many thanks in advance.

Check routing table and your lan cable.
