NFS problems - mount -RPC errors

[PorkChop]

I am trying to mount on my local system.

NFS is running on the server (georgia.garagemoderne.com)

/etc/exports on the server lists the correct hosts/adresses/aliases

Here is the error I get when trying to mount :

[root@ava gable]# mount georgia.gargagemoderne.com:/remote/gable /mnt/home
mount: can't get address for georgia.gargagemoderne.com


also rpcinfo command on the server or local machine gives a command not found error..?

Thank you -

This sound like you machine can't resolve the name "georgia..." to give an IP address. If you type
' $ nslookup georgia.gargagemoderne.com'
does your machine print out the correct IP?

If not, then a) you can add that information into /etc/hosts, b) you need to check your DNS nameserver has this machine has this machine in its database.

If so, c) check that your /etc/nsswitch.conf file has the correct settings for 'hosts' (check the HOWTOs at www.tldp.org to learn about this file and its use), d) make sure that the service 'portmap' is running.

I got it working earlier.

There were several problems, mainly being permissions.

Thanks for the help...and mark this one RESOLVED.

Ok. not RESOLVED....:(

I am still getting the error..

mount: RPC: Remote system error - No route to host


I do not have local DNS for my domain, is this neccesary? It was workign previously..

I can ping by hostname, ssh , etc...

Thank you -

[root@georgia root] #

The error message is the same ...

[root@ava gable]# mount georgia.domain.com:/remote/pictures /mnt/pictures
mount: RPC: Remote system error - No route to host
[root@ava gable]#


Thank you -
PorkChop

[ewdi]

the error means the hostname is not valid or your connection is not set, that's the only reason an nfs couldnt route to a host

[PorkChop]

I tried by IP and now I get a different error :

[root@ava gable]# mount 192.168.1.100:/remote/pictures /mnt/pictures mount: RPC: Program not registered
[root@ava gable]#


I restarted NFS/Portmap on the server, both are set to run on level 3, and 5.

I can ssh to that IP no problem...

thank you-

mount: RPC: Program not registered

Hmm, are you quite sure nfsd is running on the server? There should be several "[nfsd]" threads and an "rpc.mountd" in the server's process list, and "rpcinfo -p server" should include "nfs" and "mountd" entries.

[root@ava root]#


Am I missing anything...?


Thanks for all the help..

[bradthemad]

That looks good... how about running a "rpcinfo -p georgia" on ava, to make sure the client can see all the services on the server?

Also, whenever you restart nfs (or nfslock, or any RPC service) make sure portmap is running BEFORE starting it back up. Stop portmap last, and start it first. Starting nfs before portmap will cause this same behavior.

Here is rpcinfo -p

from ava -

[root@ava root]# rpcinfo -p 192.168.1.101
rpcinfo: can't contact portmapper: RPC: Remote system error - No route to host
[root@ava root]#


And now from georgia ...

Is the order listed here the order the services were started?

Thanks for your help..

PorkChop

[bradthemad]

[root@ava root]# rpcinfo -p 192.168.1.101
rpcinfo: can't contact portmapper: RPC: Remote system error - No route to host


Back to this again... how are these two machines connected? Are they on the same subnet? Does either have any iptables rules in effect?

Is the order listed here the order the services were started?

For the most part...

[PorkChop]

I turned the firewall off on the server, and can now mount all the directories.

Now to figure out exactly which ports need to be open..

Thanks for everyones help!!!

[PorkChop]

I just installed Firestarter, and configured it.

Now I have firewall, AND NFS...!!!!!

Thanks again..

PorkChop!
