Description rodrigob 1999-08-25 13:57:54 EDT
Tested with: RedHat Linux/i386 6.0 and RedHat Linux/sparc
6.0 (bet it happens on the other archs too)
Kernel: 2.2.11
NFS Package: knfsd-1.2.2-4

Lets suppose linux1.mydomain is a sparc machine, and
linux2.mydomain is an i386 machine.

When it works:

linux1# mount linux2:/home /mnt
linux2# mount linux1:/home /mnt
linux1# mount aix1:/home /mnt
linux2# mount aix1:/home /mnt
aix1# mount aix2:/home/mnt

When it does not work:

aix1# mount linux1:/home /mnt
aix1# mount linux2:/home /mnt

I get the following error message:

aix1# mount linux1:/home /mnt
mount: 1831-010 server linux1 not respondingmount: retrying
linux1:/home

But, as you can see, the service is running:

aix1# rpcinfo -p linux1
   program vers proto   port  service
    100000    2   tcp    111  portmapper
    100000    2   udp    111  portmapper

    100024    1   tcp    991  status
    100011    1   udp   1000  rquotad

    100005    2   udp    878  mountd
    100005    2   tcp    880  mountd
    100005    3   udp    883  mountd
    100005    3   tcp    885  mountd

And I have all I need on my aix machine:

aix1# rpcinfo -p
   program vers proto   port  service
    100000    4   tcp    111  portmapper
    100000    3   tcp    111  portmapper

    200001    1   tcp    745
    200001    2   tcp    745
    100021    1   udp   1125  nlockmgr

    100021    1   tcp   1026  nlockmgr
    100021    2   tcp   1026  nlockmgr
    100021    3   tcp   1026  nlockmgr
    100021    4   tcp   1026  nlockmgr

So, I wonder why I does not work.
Any tips ? Any other test ? Anything else I haven't checked
?

More information about the tests I performed:

linux1# who
rodrigob pts/0    Aug 25 17:23 (aix1.mydomain)

aix1# showmount -e linux1
export list for linux1:
/home		aix1.mydomain,linux2.mydomain

These are working. No clues about any other test I can perform.
Comment 2 Jeff Johnson 1999-08-25 14:29:59 EDT
Try the latest knfsd-1.4.7 package from Raw Hide. You should probably
also install and run the latest kernel-2.2.11 package because of
the knfsd version specific patches in the kernel.

I suspect what's broken is the (broken!) NFSv3 service that the
knfsd-1.2.2 daemon advertises. You might check in /etc/rc.d/init.d/nfs
and make sure that you are starting rpc.mountd with
	--no-nfs-version 3

Please reopen this bug if the above does not fix your problem.
