NFS mount broken

[sle85276]

Hello,


from time to time i'm using NFS to access files located on my desktop (nfs server/debian wheezy) on my pandora (nfs client). This is suddenly broken (still worked yesterday). The pandora sees the desktop inside the network:


------------------------------------------------------------------------------------------------------


arm-dev:/tmp$ nmap sle3


Starting nmap 3.81 ( http://www.insecure.org/nmap/) at 2015-05-23 10:59 CEST


Interesting ports on sle3 (192.168.179.32):


(The 1657 ports scanned but not shown below are in state: closed)


PORT STATE SERVICE


22/tcp open ssh


111/tcp open rpcbind


139/tcp open netbios-ssn


445/tcp open microsoft-ds


2049/tcp open nfs


8080/tcp open http-proxy


Nmap finished: 1 IP address (1 host up) scanned in 0.264 seconds


------------------------------------------------------------------------------------------------------


but from the logging of mount command it looks to me like the pandora never trys to access the server:


------------------------------------------------------------------------------------------------------


arm-dev:/tmp$ sudo mount.nfs sle3:/usr/src /sle3/src -vvv


mount.nfs: timeout set for Sat May 23 11:02:31 2015


mount.nfs: text-based options: 'addr=192.168.179.32'


mount.nfs: text-based options: 'addr=192.168.179.32'


[snip]


mount.nfs: text-based options: 'addr=192.168.179.32'


mount.nfs: text-based options: 'addr=192.168.179.32'


mount.nfs: Connection timed out


arm-dev:/tmp$


------------------------------------------------------------------------------------------------------


Does anyone have an idea, where to start investigating this problem.

what do you have in exports and fstab?

Look at the server's log.

Try to do a local mount on the server.

Try to mount with another device.

The NFS mount works from local (NFS server) and remote, but mounting from remote is slow (just a feeling).

I'm still seaching for the log files of the NFS server

Finally i found a solution:


sudo /etc/init.d/portmap start


or to make the change persistent


sudo update-rc.d portmap defaults
