Description of problem:
I am using nfs-utils-0.3.1-5 on the NFS server (Linux). The client is
an HPUX 11 HP 9000/785. I get a 'No locks available' error on the client.
The server logs a : "kernel: nfsd: request from insecure port
(5900fee9:49437)!" in the messages file, even thought the exports file on
the server specifies :
Steps to Reproduce:
1.share a directory from Linux 7.1
2.mount the share from HPUX 11
3.write a short program that uses fcntl to lock a file on the NFS share
Actual Results: fcntl() returns -1, perror() prints "No locks available"
Expected Results: Lock should have been aquired. When the client is a
this works fine. When the HP-UX connects to an NFS share on the
Solaris box this work fine. Only client HP , server Linux seems to
nfsd and lockd are loadable modules, /etc/init.d/nfs start , and
/etc/init.d/nfslock were run
Sounds like lockd is dying on the server. Can you see the lockd process on the
server after the failure?
There is a later nfs-utils available (0.3.1-8). Can you try that?
Also, lockd is start automagically in the kernel in kernels 2.2.18+, so you
should need to run the lockd init script if you're running a recent enough

Sorry, read "...so you shouldn't need to..."
OK, problem solved. After some time went by, (about 2 hours), I tried
it again, and this time it worked. Looks like the lockd servers
needed some time to get their act together.
In retrospect I believe the bug originated from trying to use
NFS locking, without starting the '/etc/init.d/nfslock start'
server. The loadable kernel modules (nfs and lockd) were allways
present, but I guess starting it this way does something good for it.
