Hi, <blockquote class="replbq" style="border-left: 2px solid rgb(16, 16, 255); margin-left: 5px; padding-left: 5px;"> We have one Fedora core5 Server for NIS and NFS running on it and there is also a second server for NFS. We have two NFS servers to distribute the load as well as increase disk quota for users. We have also the second NFS server configured as a NIS secondary for more load balancing. The configuration works fine most of the time but sometimes it is seen that the server either stops authenticating the client or does not mount the home directory of clients and reports a rpc time out.The log messages generated at that time are as below: ***The client side log messages comming are: Aug 31 15:25:29 localhost automount[2270]: >> mount: RPC: Timed out Aug 31 15:25:29 localhost automount[2270]: mount(nfs): nfs: mount failure 172.16.88.13:/home1/sachsrinu on /home/sachsrinu Aug 31 15:25:29 localhost automount[2270]: failed to mount /home/sachsrinu Aug 31 15:25:29 localhost gdm[2175]: gdm_slave_session_start: Home directory for sachsrinu: '/home/sachsrinu' does not exist!

In /etc/yp.conf we have added the domain name server 2. In /etc/nsswitch we made changes so nsswitch file is follows # # /etc/nsswitch.conf # # An example Name Service Switch config file.

We have made changes to the file /etc/sysconfig/network and added lines to file as NETWORKING = yes NISDOMAIN = nisserver domain name ***The NFS server side configuration 1. In /etc/export we have added the ip address of system to which it is exported with (rw,sync). 2. we have directory mount for some user from /home and some as /home1 in the /etc/passwd file as some user are in nfs1 and some user are in nfs2. ***The NFS client side 1.We have changed the file auto.master in which we added the first home as nfs1 and second home as home1 for nfs2 2.we have auto.home in client for nfs1 3 we have auto.home in client for nfs2 Please Reply if you know the solution to the problem.
