I have problem on a home network. there is a server and client pc. Both ping and ssh to each other are ok.
i set up /etc/exports at server as
/data client(rw,root_squash,sync)
when I try to mount this on client, i got error as
mount: RPC: Program not registered
or
can't contact portmapper: RPC: Remote system error - No route to host
at client
/usr/sbin/rpcinfo -p server
rpcinfo: can't contact portmapper: RPC: Remote system error - No route to host
at server:

I looked at nfs howto a
thttp://nfs.sourceforge.net/nfs-howto/ar01s07.html#unable_to_mount_fs
it says:
If you get the error Remote system error - No route to host, but you can ping the server correctly, then you are the victim of an overzealous firewall. Check any firewalls that may be set up, either on the server or on any routers in between the client and the server. Look at the man pages for ipchains, netfilter, and ipfwadm, as well as the IPChains-HOWTO and the Firewall-HOWTO for help.
where to check the firewall settings?
thanks
