No Route To Host +NFS

shawniecas · 11-28-2007, 09:10 AM

Ok, I've been trying to set up NFS for a week now, and according to everything I've followed it should be working. When I boot up, it says

"Portmap: Unrecognized Service"
and something like "NFS failed: No route to host"

I can ping and ssh back and forth, so I don't understand the no route part, and I have portmap running when I type rpcinfo -p. It is running several versions on tcp and udp on port 111 on both machines. Any ideas on how to fix this problem??

The thought I have is what have you got in your /etc/hosts.deny and /etc/hosts.allow files? These can block NFS hosts connecting.

For completeness, here is what I see on my systems for rpcinfo.

Code:

/usr/sbin/rpcinfo -p
   program vers proto   port
    100000    2   tcp    111  portmapper
    100000    2   udp    111  portmapper
    100024    1   udp   1027  status
    100024    1   tcp   3329  status
    100005    1   udp    654  mountd
    100005    1   tcp    657  mountd
    100005    2   udp    654  mountd
    100005    2   tcp    657  mountd
    100005    3   udp    654  mountd
    100005    3   tcp    657  mountd
    100003    2   udp   2049  nfs
    100003    3   udp   2049  nfs
    100003    4   udp   2049  nfs
    100003    2   tcp   2049  nfs
    100003    3   tcp   2049  nfs
    100003    4   tcp   2049  nfs
    100021    1   udp   1028  nlockmgr
    100021    3   udp   1028  nlockmgr
    100021    4   udp   1028  nlockmgr
    100021    1   tcp   3923  nlockmgr
    100021    3   tcp   3923  nlockmgr
    100021    4   tcp   3923  nlockmgr

Make sure you have all the services running.

Here is what I have in /etc/hosts.deny file.

Code:

cat hosts.deny
#
# hosts.deny    This file describes the names of the hosts which are
#               *not* allowed to use the local INET services, as decided
#               by the '/usr/sbin/tcpd' server.
#
# The portmap line is redundant, but it is left to remind you that
# the new secure portmap uses hosts.deny and hosts.allow.  In particular
# you should know that NFS uses portmap!
# Copied exports, hosts.allow and hosts.deny from 9.2 March 19/06
portmap:ALL
lockd:ALL
mountd:ALL
rquotad:ALL
statd:ALL
ALL:ALL

and /etc/hosts.allow file

Code:

cat hosts.allow
#
# hosts.allow   This file describes the names of the hosts which are
#               allowed to use the local INET services, as decided
#               by the '/usr/sbin/tcpd' server.

Note, the IP addresses are unique to my home network. Just make sure you are allowing all clients you want to allow.

Hope this helps.
