Both (Solaris 10 & AIX) systems are production system. I am not able to give the output's of the /etc/hosts & $HOME/.rhosts files, because the customer is not ready to provide with the information. The only thing which is bothering me is that I am able to get the remote shell.....so why the remote shell commands are not working directly from Solaris10..???

Sounds like your systems using IPV6 , not IPV4.
There was a bug in earlier releases of Solaris 10 where rsh <hostname><command> doesn't work in IPV6 systems,
but rsh <hostname> does. I think was fixed is Solaris 10_23

cat /etc/release to see what release you have.

BUGID 4760974 was logged about this.
Code:
In IPv6 systems, rsh a hosts with "ls" doesn't print out anything.

In IPv4 systems, rsh a host with a UNIX command works.

Just unconfigure IPV6.

Good call I completely forgot about that becasue we don't use IPv6, 23 was a problematic release, I would go to 24, which has a few dependencies. If you have an entitlement, the EIS 3.0.11 patch cluster seem to be a good release.

I wasn't recomending to go to 10_23, just letting him know that that was the first release that had the fix.

Yep, I understood that, but was just making sure it wasn't interpreted as "go to 23"

I had the same problem from AIX to AIX when our DNS-Server crashed

I could rlogin from a to b but not execute commands (with hosts entry)

when DNS was up again rsh worked instant, I'cant tell you what the problem was, but obviously it was about name resolution, reverse lookup, full qualified or not full qualified DN problem, search in that direction
