telnet problem

hi,
I have a cluster with 3 machines. I cannot telnet on the third one today. It does not work when I use rlogin 3rd_host on the first machine. But ping the 3rd_host is ok. There are nothing in the 3rd_host's syslog.log.
Could someone tell me why? thank u.

Re: telnet problem

It might help if you would reveal the actual
commands used, and the actual output from
them. "It does not work" is less than
helpful.

Re: telnet problem

when I used command :
cs3#ps -ef|grep nsr
suddenly the session was closed.
After that I cannot login cs3.
I login cs1, and used command:
cs1#telnet cs3
trying 10.134.2.48
telent: Unable to connect to remote host:Connection refused.

thank you

Re: telnet problem

Ok. "Connection refused" normally means that
you can talk to the other system, but that
it's unwilling or unable to run the Telnet
daemon for you. There could be a problem
with inetd, or some general resource problem
which prevents the system from spawning a new
process for you.

Is Telnet the only thing which fails? Have
you tried "rsh" (or FTP, or ...)?

If you can get logged in somehow, you might
try "inetd -h". ("man inetd".) Or killing
and restarting inetd, if you get desperate.

I have tried rlogin
cs1#rlogin cs3

so I have cs3 rebooted.
