Martin,
Sorry to bother you again, but it seems the problems aren't over. It
seems like the client only successfully boots sometimes. Other times it
stops on the premount faze and gives some errors like "error in
/scripts/nfs-bottom/tcos_squashfs: //root/sfs/base.sfs not found" etc...
I also attached the service log which has the last entry of " INFO |
jvm 1 | 2010/05/03 15:44:34 | 15:44:34,814 INFO [AbstractPXEService]
Expiring expired conversation
Conversation[1/00:23:7d:cb:dd:ab/2127289771]: age=67969, client=[Client
name=TC3895, description=null, ip=0.0.0.0, location=English
applicationGroups={}, applications={}]"
I tried building the OTC server from scratch in case some things got
messed up some how. But the client still only boots properly
periodically. Could this still be related to network communication
issues?

Brian

Hey Martin,
Seems like we were able to get it working. The network guys said they
used some sort of option to forward the broadcasts, perharps something
similar to the IP helper address system. Anyways, thanks again for the
advice because it seemed to point them in the right direction. I guess
my only other question is, can the OTC server reboot thin clients
remotely without having to log in to each thin client individually?
Regards,
Brian

Thanks Martin, I will talk to them again. We actually tried option 66
and 67 with those options and also added a thin client manually, but for
some reason when I checked the logs the client still wasn't contacting
the OTC server. I will look into these options further and I will get
them to test the IP helper address. Thanks again for your help.

Brian Clarke

hi brian,
i'am pretty sure the concerns of your network admins are unnecessary.
if you have multiple ip helper-addresses defined, any UDP broadcasts
recieved
on the allowed udp ports will be unicasted to EACH of the IP helpers.
as the openthinclient DHCP proxy does not interfere with DHCP servers
it's
absolutely save to add the second ip helper-addresses.
furthermore this is best practice for using DHCP proxies and i've seen
this
setup working dozens of times at more complex otc installations.
however, there is an alternative solution for your problem. apparently
you will
lose the "auto-discover" feature of openthinclient and you have to add
your
thin clients manually:
you can add two DHCP options to tell your thin client where to boot from
and
which Network Bootstrap Program (NBP) to use. these options depend on
your DHCP
implementation and should be set to:
next-server/TFTP Boot Server Host (DHCP Option 66):
<IP_OR_NAME_OF_YOUR_OTC_SERVER>
filename/Bootfile Name (DHCP Option 67):
pxelinux.0 or /pxelinux.0

martin
