Problems with remsh

Alan Meyer_4 — Wed, 02 Nov 2005 16:49:24 GMT

When connecting to a few of my machines via remsh, I was receiving the following message:

remshd: getservbyname

I then checked the inetd process and configuration and also issued a inetd -c to no avail.

At this point I could still telnet into the machine.

I then issued a /sbin/init.d/inetd stop and then a start and the message changed to this:

rcmd: connect: nodename: Connection refused

and telnet connections were started to be refused by host.

This is only happening on 3 of my machines out or 37 and "to my knowledge", no changes have been made to any of the boxes.

Well, you didn't bother to identify the OS version(s) but for 11.11, PHNE_33791 may well fix you.

Actually these are all 11.00 boxes. But this is not affecting ALL my 11.00 boxes.

In that case, check out PHNE_33790.

does not contain an entry for "kshell", and displays the

Could you check if kshell and ekshell are uncommented in the /etc/services file ?

Is it possible that the services file itself can become corrupt??? The reason I ask is the I am also now getting a bunch of messages in the syslog that state

Nov 2 11:45:44 beryl inetd[940]: telnet/tcp: Unknown service

I have checked the kshell & ekshell services are not commented.

Yes, it's possible that you have a corrupt services file and even more possible if you are running NIS, NIS+, or LDAP and have a corrupt services map/table.

It was actually a corrupt NIS slave server. When we ypset these servers to the master server and then ran inetd -c, everything worked great.

So it seems that the slave server in question does not get refreshed whenever the master server gets rebooted. Sounds liek another thread to me....
