Hello
I need to use rsh but I can't do it on a server. I actually rsh to the server, but I can't from a new server.

I can rsh from server to other servers but i cant to server b. Problem is server b. I can also rsh to server b from other servers.

Server A to rsh server B ----> var/log/messages B server

server B firewall not active, iptables not active

xinetd[2545102]: START: shell pid=842131 from=::ffff:..........
xinetd[842131]: FAIL: shell address from=::ffff:.......
xinetd[2545102]: EXIT: shell status=0 pid=842131 duration=0(sec)

Server A rsh command
poll: protocol failure in circuit setup
 


Using rsh appears to be rare these days, where once it was a major networking service. Most users today use ssh and it's family of commands.

In any case, I'd check the rsh server configuration files. Simple configs like "disable=yes" may slip by. I expect you've got all that under control though if you are using it extensively.

There's an interesting article here about that error message "poll: protocol failure in circuit setup" which may throw light on the problem: https://www.suse.com/support/kb/doc/?id=000015992.
