Hello,

I have a server running RHEL 4 with two Fedora Core 5 clients.

When I reboot the server I can no longer SSH into my client machines.

When I SSH to the clients I am prompted to log in and then the screen just turns and stays black - I can't run any commands or access the system. I have webmin running and cannot access that either once I reboot the server.

I am wondering if it has something to do with the way the NFS mounts are set up.

The server and the clients are all cross mounting directories (/home and 2 disks from client 1, /backup from client 2 and /usr/local from the server).

Any help appreciated, it's kind of a big issue.

EXPORTS

Server:
/export/local client1.domain.com(no_root_squash,rw,sync)
/export/local client2.domain.com(no_root_squash,rw,sync)

Client1:
/export/home server.domain.com(no_root_squash,rw,sync)
/export/home client2.domain.com(no_root_squash,rw,sync)
/export/disk1 server.domain.com(no_root_squash,rw,sync)
/export/disk1 client2.domain.com(no_root_squash,rw,sync)
/export/disk2 server.domain.com(no_root_squash,rw,sync)
/export/disk2 client2.domain.com(no_root_squash,rw,sync)

Client2:
/export/backup client1.domain.com(sync,no_root_squash,rw)
/export/backup server.domain.com(sync,no_root_squash,rw)

FSTAB

Client1:
/home /export/home bind bind 0

client2.domain.com:/export/backup /mnt/backup nfs defaults 0 0

Client2:
