Hi,

Problem: I'm not able to mount a remote disk on "nas01" to "arthur".
Problem must be on arthur, because I can mount nas01 from a third computer (marvin)

/etc/fstab reads
...
nas01:/Qmultimedia /nas/multimedia nfs noauto,user,rw,hard,intr 0 0
...

ARTHUR$ mount /nas/multimedia/ on arthur answers
mount.nfs: rpc.statd is not running but is required for remote locking.

I found out, that running
ARTHUR$ /etc/rc.d/rc.rpc start
results in the following error:
rpc.statd[6532]: unable to register (statd, 1, udp).

and "rpcinfo -p" says:
rpcinfo: can't contact portmapper: RPC: Remote system error - Connection timed out

But portmapper is running!
ARTHUR$ ps axu | grep portmap
bin 30092 0.0 0.0 1896 412 ? Ss 18:03 0:00 /sbin/rpc.portmap

No problem asking the remote computers nas01 and marvin:
ARTHUR$ rpcinfo -p nas01
program vers proto port
100000 2 tcp 111 portmapper
100000 2 udp 111 portmapper
100003 2 udp 2049 nfs
100003 3 udp 2049 nfs
100003 2 tcp 2049 nfs
100003 3 tcp 2049 nfs
100021 1 udp 1026 nlockmgr
100021 3 udp 1026 nlockmgr
100021 4 udp 1026 nlockmgr
100024 1 udp 682 status
100024 1 tcp 685 status
...

ARTHUR$ rpcinfo -p marvin
program vers proto port
100000 2 tcp 111 portmapper
100024 1 udp 56126 status
100024 1 tcp 52366 status
100021 1 tcp 60540 nlockmgr
100021 3 tcp 60540 nlockmgr
100021 4 tcp 60540 nlockmgr


If I check arthur from marvin:
MARVIN$ rpcinfo -p arthur
program vers proto port
100000 2 tcp 111 portmapper
100000 2 udp 111 portmapper

Now, there is an answer from arthur, but only portmapper, without nlockmgr and status.


What is happening on arthur??
Any help appreciated!

Marked as "solved" ...
... but only cured, actually... :-)

1st change: I switched off ipv6:
ARTHUR$ cat >> /etc/modprobe.d/blacklist.conf <<EOD
blacklist ipv6
EOD

I'm using wicd for my wlan. Documentation said: do not "use" rc.inet[12] but leave them untouched. So I did "chmod -x /etc/rc.d/rc.inet[12]"
2nd change: re-activate
ARTHUR$ chmod +x /etc/rc.d/rc.inet[12]

ARTHUR$ reboot

ARTHUR$ rpcinfo -p
program vers proto port
100000 2 tcp 111 portmapper
100000 2 udp 111 portmapper
100024 1 udp 48785 status
100024 1 tcp 32903 status

working.
But still interested in the explanation.

retry after rastarting all of the services,
first stop nfs server, then rc.rpc

run rc.rpc, run nfs server, and retry

Hi ozanbaba,

nfsd is active on nas01, only. The other computer ("arthur") is a client.
Rebooting arthur and running /etc/rc.d/rc.rpc gives
Starting RPC portmapper: /sbin/rpc.portmap
Starting RPC NSM (Network Status Monitor): /sbin/rpc.statd

$ ps axu | grep portmap
bin 2692 0.0 0.0 1896 412 ? Ss 19:00 0:00 /sbin/rpc.portmap
$ ps axu | grep statd
$ tail /usr/adm/syslog
...
Dec 27 19:03:09 arthur rpc.statd[2696]: unable to register (statd, 1, udp).
...

same story as described above.

additional informations:
Running slackware-13.0 on arthur.
On my second computer (slackware-12.1) nfs-mount works fine, so the problem is on arthur

incompatiblity between two systems?. google suggest a bug in the portmap or NSM.

portmap-6.0 both in slackware-12.1 and slackware-13.0

I'm pretty sure, I made the mistake - but don't know, where ...
