Check (/etc/services)..
Make sure the line that has "kshell" is not commented out.
Sometime You'll get this error because this line is commented out. Or if you are using NIS then check your resolve.conf and nsswitch.conf file in /etc

Goodluck

Double check the file /etc/services on the machine that you're trying to remsh to and make sure the entries that says ..
kshell ...
ekshell ...
are not commented. If they are uncomment them. These are Kerberos remote shell that needs to be enabled for the "r" commands to work.

Looks like your shell,kshell and ekshell have been commented out in your /etc/services file. Uncomment them and run inetd -c and then try again.

Ok, thanks i uncommented kshell and ekshell, but Why i need to use this services ? if remsh its common service, this service used kerberos by default ?

remsh is similar to rlogin in that it needs to be able to resolve the hostname properly and that it is allowed access vi a .rhosts file or /etc/hosts.equiv. Validate that the hostname resolves correctly by using

nslookup
and nslookup

and validate that

rlogin
works.
If these are both fine then also check /etc/services for the shell entry on the target system. Shell uses port 514/tcp

If you look at the timing of my post, it is stamped same as the other prior posts. Well, I am not begging you for the points.

Whether you use kerboros or not, remsh does look for the ports 544 and 545. This is a patched up feature added recently.

And that patch ( for example for 11.0) is PHNE_23003 r-commands cumulative.
