NFS
Hello,
I'm running an NFS Server on my Fedora machine and trying to mount it on my OpenSuse netbook.Right now I'm getting a "permission denied error" when I try to mount NFS on my netbook. (Yesterday I could mount, but could only read not write... strange)
my Servers IP is 192.168.1.45
my Netbooks IP is 192.168.1.42
/etc/export on Server
Code:
/home/bob/Music 192.168.1.42(rw,no_root_squash)
/etc/hosts.allow on Server
Code:
sshd: 192.168.1.0/255.255.255.0
nfsd: ALL
portmap: ALL
mountd: ALL
/etc/hosts.deny on Server is empty
mount command on my netbook
Code:
mount -v 192.168.1.45:/home/bob/Music /home/bob/nfs
mount: no type was given - I'll assume nfs because of the colon
mount.nfs: timeout set for Sat Jan 1 16:16:34 2011
mount.nfs: trying text-based options 'nfsvers=4,addr=192.168.1.45,clientaddr=192.168.1.42'
mount.nfs: mount(2): Permission denied
mount.nfs: access denied by server while mounting 192.168.1.45:/home/bob/Music
Thanks for your help |

Which version of nfs are you running? For v4 you must specify "-t nfs4" in mount command. Are you running firewall on the client or server? For the test is better to disable hosts.allow by renaming this file. Check also on the client machine:
Code:
rpcinfo -p 192.168.1.45

I am running version 4, specifying the format with -t nfs4 did not help.
The firewall does have an exception for nfs, (after all it did work a bit this morning).
On my Netbook
Code:
/home/bob # rpcinfo -p 192.168.1.45
rpcinfo: can't contact portmapper: RPC: Remote system error - No route to host
/home/bob # rpcinfo -p 192.168.1.42

Can you check connectivity between your netbook and your fedora server? like can you ping the server? |

Also check
Code:
route -n
iptables -S
on both server and client. They are physically connected through switch or router? If router check these command also on it. |

You are getting a permissions denied. Make sure that the uids match on both ends.

I can configure my Server with SSH form my netbook so the connection is fine 
What do you mean with user id? How I have to make them match? |

NFS works properly with the uids matching on both machines.
id <username>
There should be a uid entry. Make sure that they match on the systems that you are using NFS to and from.

Make sure you nfs client services are running. Did you use Yast2 to set up client?

Before checking uids and permissions, first you must get proper response on client machine for
Code:
rpcinfo -p 192.168.1.45
Now you get "no route to host", portmapper can't even connect to your server to establish nfs connection. This very likely means that your firewall block it, did you enabled port 111 and 2049 on server and client?
Check also on the client: For me I must enabled idmap for nfs working.

Okay UIDs dont match. Port 111 was blocked by the firewall, but 2049 was not.
How do I have to set up my NFS Client?
