I get the following error when i try to mount a file system
located on a different computer on my network:

mount: RPC: Port mapper failure - RPC: Unable to receive


According to the NFS how to, everything on the server is setup correctly. Here is my /etx/exports file from the server:


/net 192.168.1.100(rw)


it's just a 1- liner to allow /net to be mounted on 192.168.1.100 (the client) via nfs with read and write permissions.

i even checked to make sure nfs was runnin, here is the output from rpcinfo -p from the server:

program vers proto port
100000 2 tcp 111 portmapper
100000 2 udp 111 portmapper
100024 1 udp 1025 status
100024 1 tcp 1024 status
100011 1 udp 629 rquotad
100011 2 udp 629 rquotad
100011 1 tcp 632 rquotad
100011 2 tcp 632 rquotad

100005 1 tcp 1027 mountd
100005 2 udp 1029 mountd
100005 2 tcp 1027 mountd
100005 3 udp 1029 mountd
100005 3 tcp 1027 mountd

100021 1 udp 1030 nlockmgr
100021 3 udp 1030 nlockmgr
100021 4 udp 1030 nlockmgr

notice that nfs and portmapper are both runnin


here is the same command from the client:

program vers proto port
100000 2 tcp 111 portmapper
100000 2 udp 111 portmapper
100024 1 udp 32768 status
100024 1 tcp 32768 status
391002 2 tcp 32769 sgi_fam


once agan notice that portmapper is running. As even a final step I added the client to the hosts.allow file on the server just to make sure the host had permission..but i still manage to get that error. The error again is:

mount: RPC: Port mapper failure - RPC: Unable to receive

any ideas or suggestions? The troubleshooting section of the HOWTO didn't seem to have my problem listed and everything on the server and client appear to be working just fine.

still no help for me huh?

How are you trying to mount it on the client side ??

Maybe of some help if you are using tcpwrappers
Your hosts.allow may need all the deamons used for nfs.

lockd: 192.168.1.100
mountd: 192.168.1.100
rquotad: 192.168.1.100
statd: 192.168.1.100

in response to both of your posts:

I mount on the host with the mount command:

mount 192.168.1.101:/net /

And I also have it set to mount at boot time using
an entry in the fstab but during boot it fails with the
same error.

and i tried to set up my hosts.allow already the way you have it but i still get the same error.

Well first off, I wouldn't try to mount the remote directory to your / direcotry. Create a /net to mount it to. This is how I have my fstab entry on one of my machines:

192.168.1.10:/data /export/data nfs rsize=8192,wsize=8192,timeo=14

And like lopez suggested, make sure you do have all the correct daemons running and maybe using the tcpwrappers.

Your mount point is definitly the problem as tricky said.
create a new directory somwhere like /home and try

mount 192.168.1.101:/net /home/"new directory"
