UNIX for Dummies Questions & Answers

Hi all,

I have two problems, My system is SunOS 5.9:

1- I have installed sudo but I have a problem logging user activities on other hosts, the way I installed it is that I installed sudo and the sudoers file in a shared directory on a NFS server which is mounted by all computers on the newtork. I have configured the sudoers file to log into a file in the shared directory by the following command:

Defaults logfile=/share/sudo.log

but this only works for command that are run on the server itself, and won't log commands done on hosts. Any way to solve this problem?

2- My manager requested a configuration of NFS servers where all the computers can see the hard drives of all other computers, so I changed the /etc/dfs/sharetab to share the root directory on all the machines and I changed the /etc/vfstab to mount the root directories of all other machines on each machine. This configuration works fine, but when a machine is turned off the other machines will not restart successfully nor will they see other working remote machines. I guess this is because of the lack of a timeout mechanism in the NFS configuration, is there anyway to configure an NFS client to stop looking for a remote server after, for example, 5 seconds of no response, and then give control back to kernel?


Thanks!

your sudoers log need to be writable by root at all the other boxes --- not just the NFS server sharing the directory ... might not be what you want since doing so may compromise the exported share and the NFS server ...

as for your NFS hang ... you are running into stale NFS connections ... not a good idea to force mount the exported shares --- as in editing /etc/vfstab --- for what you need since that setup pretty much require that all boxes be up all the time or to reboot all at the same time so you don't run into NFS connectivity issues ... you might want to consider automounting NFS so you only mount the networked filesystems when needed .... see "man automountd"
