Re: remsh

Hope this helps!

Re: remsh
Seems like you are dropping packets.
remsh hostname cmd will require 514 port
Can you do a diagnostic:
telnet DRSERVER 514
Look for the words: connected to
synema:/tmp/# telnet DRSERVER 514
Trying 10.214.16.131...
Connected to DRSERVER.
Escape character is '^]'.
Connection closed by foreign host.
and do a
ping DRSERVER -c130 -w 2 -i 0.01
This is a burst, how many timeouts or drops do you get ? Are all okay , if yes,
then it is not a connection problem, but something else.
Try to restart the remshd deamon on the remote host.
Then try to diagnose dns
nslookup with and without suffix domain name, bot forward and reverse lookup.
Do the same from the target host.
What do the symptons tell you ?

Re: remsh
nslookup is ok
ping ok
telnet DRSERVER 514 is OK
and as I mentioned remsh also works fine, but when i pass and unix command it fails, though it should not fail. it works on other servers.
prashant, following is the output of
# grep remsh /etc/inetd.conf
shell stream tcp6 nowait root /usr/lbin/remshd remshd
# The standard remshd and rlogind do not include the Kerberized
kshell stream tcp nowait root /usr/lbin/remshd remshd -K
Would there be any permissions/security issues, that cause the failure.
Please suggest,
Thanks

Re: remsh
you can do a tcpdump to find what is causing the issue.
you need to check the route between the source and destination servers.
netstat -nr
also check /var/adm/inetd.sec to see if you have anything defined there.
