unable to mount /home dir in a client machine

abhishek124 · 05-30-2005, 01:30 AM

Hi
I have a nis server and i want to mount home directory.
in /etc/exports file i have done the following configuration
/home *(rw,sync)

chkconfig nfs on
chkconfig iptables off
chkconfig nfslock on
/sbin/rpc.statd start
service portmap start
chkconfig portmap on
chkconfig ypserv on

in vi /etc/hosts.allow
portmap : 132.0.0.0 : allow
ALL : 132.0.0.

when i mount the /home directory in a client machine
mount 132.0.0.2:/home /home

i get following error
Mount RPC: unable to receive errno=Connection refused

Can anyone help me

saneax · 05-30-2005, 02:12 AM

in /etc/exports file try this...
/home 132.0.0.0/24(rw,sync)

check...
/etc/hosts.allow
/etc/hosts.deny..

alsoin case SELinux is enabled ... diable it with 'setenforce 0'

also post the output from 'rpcinfo -p'

best luck

Hi,
Maybe you can check that the /home is correctly exported, from you client type : showmount -e 132.0.0.2

abhishek124 · 05-30-2005, 04:18 AM

WELL ON CLIENTMACHINE, I DID THIS

[root@delapache root]# showmount -e 132.0.0.2
Export list for 132.0.0.2:
/home 132.0.0.0/24
[root@delapache root]# mount 132.0.0.2:/home /home
mount: RPC: Unable to receive; errno = Connection refused

saneax · 05-30-2005, 04:20 AM

your rpcinfo output seems absolutely correct.
check the /var/log/messages for authentication faliures at the time you are trying to mount from client.
post that..
if you have a nis server from where you are exporting users and passwds.. check everything is OK... as nis client

saneax · 05-30-2005, 05:09 AM

your nfs server is not authenticating the incoming connection...

please check the following...
in /etc/hosts.deny, there shouldnt be nething (just for testing)...
in /etc/hosts.allow nothing should be there... (which means ur /etc/exports) is final authority in restricting...
restart xinetd... and restart portmap and also nfs daemons.. try and see what happens

abhishek124 · 05-30-2005, 05:30 AM

ITS GIVING ME THE SAME ERROR, HOW EVER
when i restart the nfs service

[root@delnis root]# service nfs restart

thankyou guys for helping

saneax · 05-30-2005, 08:42 AM

bad option...
read through http://nfs.sourceforge.net/nfs-howto/security.html
and http://nfs.sourceforge.net/nfs-howto/server.html

may the luck be with you

Tudor Popescu · 05-30-2005, 10:13 AM
