suspecting you / file system full on the server "please check on console" of the server,

or

could be network issue, also pls do the below

netstat -in
who
ps -ef |grep sshd
ps -ef |grep telnet

reset the lan interfaces...
lanadmin ----> lan ----> reset lan interfaces..

rgds,

"data control flow", not "data flow control"?

Does this happen for all users, or only you?

Hi,

>>>>if i logged in as root in problem server and try telnet 0 ,then also getting same error<<<<

How did you login as root into problematic server? through console?using ssh or rlogin? or even telnet?

is it not allowing only non-root users?

was it working earlier?
