disabling nfs.core stops telnet working

[JUP]

I posted a similar message previously but was not able to get it working.

I am using HP-UX 11.00 U on a 9000 system.

I want all NFS services disabled so I edited the /etc/rc.config.d/nfsconf file and set these variables to "0"
NFS_SERVER=0 and NFS_CLIENT =0

No luck as nfs.core still wants to run and when it runs it core dumps.

So I moved /sbin/rc2.d/S400nfs.core to /tmp/S400nfs.core so nfs.core does not run.

Well I don't get the core dump anymore, but now I cannot telnet to the system. When I try to telnet to the host from the PC it just times out.

I logged on using the console (as telnet does not work) and checked if inetd was running. It was running.

So I moved the S400nfs.core file back and rebooted. I got the usual core dump but can telnet.

When I do a "file core" I get:

core: core file from 'nfskd' - received SIGSYS

which indicates that nfskd is still attempting to run.

I need telnet running yet don't want nfs running as its slows too many things down.

I have attached the core file just incase someone out there can interpret it for me.

Has anyone got any suggestions. It would be much appreciated.

Thanks in advance
JUP.

You'll find that the NFS.core needs to be able to run. I cannot remember why, but the bastion document does say why. I'm not near a system to see, so hear is a link to the document that should explain it.

I could be wrong ....

Thanks T G and Michael - your posts solved my problem. It was a delay in the telnet from starting up. The bastion doco is excellent as well.

Robert - unfortunately the link you posted does not let me log in. Thanks anyway.

The document post was a US document, and you are not a US user.

I'm posting this thread as a poster child for resolution of this issue.

Another less useful note: I do not belive that nfs.core needs to be running for telnet to work.

Though a mess up in networking can cause all networking to fail, it should be possible to not run NFS and have telnet work.
