[Ltsp-discuss] jury-rigging vs. changing default address for client network and server eth0

[John Q P. <joh...@sb...>]

Short story:
Everything is working great, except the network I am joining also uses 
the 192.168.0.0 address space.  Where do I make the changes to use 
another network address, like 192.168.2.0-254?  It seems to me that 
there are at least four or five places.

Long story:
Access to the campus network and the internet did not work.  I believe 
this was because the routing table (seen with the route command) had 
each network on different interfaces.  The default gateway on the 
campus network was set to 192.168.0.1, which conflicted with ws001 on 
the LTSP network.  I found a work-around by removing both the 
192.168.0.0 entries from the routing table, adding a default route to 
the campus network at 192.168.0.1 on eth1, and then adding the 
individual ltsp stations with the 'route add -host 192.168.0.252 eth0' 
command.  I also commented the ws001 entry in the /etc/hosts file.

The jury-rigging works well now.  I just need to add workstations to 
the routing table manually, after they are assigned IPs from DHCP.  For 
a long term solution, some options include writing a script for 
boot-time that adds and deletes the entries in the routing table (not 
very elegant) or re-addressing the LTSP network.  As I understand it 
now, that would mean changing  (1) the address ranges and  (2) the 
server address for the DHCP/PXE parts of the boot, (3) changing the 
server address variable in /opt/ltsp/i386/etc/lts.conf , and (4) 
changing the addresses listed in /etc/hosts .  Are there other places I 
need to change the network/workstation/server/gateway entries?  If I 
change the address of the eth0 during the CD-installation, will it be 
placed in the other places?

Did I get all the places that 192.168.0.0 (and 254) are specified?  Is 
this the best solution, other than asking the campus network to 
renumber?

I'm sorry if this was too thorough or long-winded.  I'm new to 
manipulating routing tables, and I talk a lot.
