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

<br><br>I looked at nfs howto a<br><br>thttp://nfs.sourceforge.net/nfs-howto/ar01s07.html#unable_to_mount_fs<br><br>it says:<br><br><span style="font-style: italic;">
If you get the error </span><span style="font-style: italic;" class="emphasis"><em>Remote system error - No route to host</em></span><span style="font-style: italic;">,
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 <strong class="command">ipchains</strong>, <strong class="command">netfilter</strong>, and <strong class="command">ipfwadm</strong>, as well as the </span><a style="font-style: italic;" href="http://www.linuxdoc.org/HOWTO/IPCHAINS-HOWTO.html" target="_top">
IPChains-HOWTO</a><span style="font-style: italic;"> and the </span><a style="font-style: italic;" href="http://www.linuxdoc.org/HOWTO/Firewall-HOWTO.html" target="_top">Firewall-HOWTO</a><span style="font-style: italic;">
for help.</span><br><br>where to check the firewall settings?<br><br>thanks<br>Yuan<br><br>
