remshd problem

V.Venkatesh_1 — Fri, 20 Oct 2006 00:22:13 GMT

I have a server running HP-UX 11.11. Its a trusted host. However we are using remsh to run SRDF process. Basically the database server (also running HP-UX 11.11) connect to this server for BCV/SRDF copy using remshd. For some reason this server stopped accepting remsh connections. I am able to remsh out but not remsh in. Could somebody help me what's wrong. This is a production server and there was not change since the last run. Your help would be highly appreciated.

Error mesaages. Check if account is locked/disabled/expired.

Any changes with respect to host name/ip change?

Shalom,

The most common cause of this issue is expired password.

A change in ownerhip and permissons of the .rhost files could also lead to the sudden failure of this process.

I appreciate your help. However I have verified that account is not locked.
/usr/lbin/getprpw root
uid=0, bootpw=YES, audid=0, audflg=1, mintm=-1, maxpwln=-1, exptm=-1, lftm=-1, spwchg=Thu Oct 19 22:22:07 2006, upwchg=Sat Jul 8 06:28:28 2006, acctexp=-1, llog=-1, expwarn=-1, usrpick=DFT, syspnpw=DFT, rstrpw=DFT, nullpw=DFT, admnum=-1, syschpw=DFT, sysltpw=DFT, timeod=-1, slogint=Fri Oct 20 01:16:07 2006, ulogint=Thu Oct 19 22:17:52 2006, sloginy=console, culogin=-1, uloginy=-1, umaxlntr=99, alock=NO, lockout=0000000
I have already reset the password. Still no luck. I have also checked the inetd.conf file. There was no change made to the permission to .rhosts file either
ls -l .rhosts
-r--r----- 1 root sys 126 Dec 27 2004 .rhosts
any other tips would be more useful

With the account that you use for remsh, just do plain telnet and login. Once logged in, do who -um and what you see in last column of above output should be in .rhosts file. Is it same as what you see in who -um?

Great! RAC.. you are right. I think the network team has made some DNS change without our knowledge and the whole thing got screwed up. Since telnet was disabled I used ssh to login to the server. Once I did who -um I found that the machine name was totally different than the entry in the .rhosts file. I edited .rhosts file to reflect the change and the problem was resolved. Thank you for your useful tips and I appreciate your time on this.
