Re: [K12OSN] LTSP server with 3 NICs? SOME SUCCESS!



We *have* made progress.  You're now TFTP-booting, and this is GOOD.

What you're now dealing with is an NFS permissions issue.  Your 192.168.3.x's are still pointing to /opt/ltsp/i386, not /opt/ltsp/i386-3.  Check out /etc/exports one more time.

Hi Scott,

I must agree in that I have received some tremendous help and I feel
so close to a solution!

I booted up the client on the NIC that works, logged into the client
window manager, opened a terminal, su'd and ran
system-config-securitylevel-tui

There were three interfaces listed: eth0, eth1, eth2

I marked the LTSP networks as trusted.

I rebooted the server and the client and tested out the client's
booting.  It still successfully booted on the NIC which it did before.
 I switched it to the other NIC, and it got past where it froze
before!!

It now stops with the following error:

mounting root filesystem:/opt/ltsp/i386 from: 192.168.3.254
mount: 192.168.3.254:/opt/ltsp/i386 failed, reason given by server:
Permission denied
mount: nfsmount failed: bad file descriptor
mount: mounting 192. 168.3.254:/opt/ltsp/i386 on /newroot/nfsroot
failed: invalid argument.

ERROR! Failed to mount the root directory via NFS!
Possible reasons include:
1 ) NFS services may not be running on the server
2 ) Workstation IP does not map to a hostname, either in /etc/hosts, or in DNS
3 ) Wrong address for NFS server in the DHCP config file
4 ) Wrong pathname for root directory in the DHCP config file

Kernel panic - not syncing: Attempted to kill init!

And that's it.  Stops there.
