</div>To help answer this, I'll need a little more info. If I understand you<br>
correctly, the "192.168..." NICs on both of your LTSP servers (you don't<br>
specify this, so I'm by necessity making an assumption here) are your "eth0"<br>
interfaces for talking to your thin clients.<br>
</blockquote><div><br>You're correct. They're not actually eth0 (we were having driver issues with the onboard eth0 NIC, so they're eth2, I think), but they're the interface that talks to all the thin clients.<br>
</div><blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;">Furthermore, both of these eth0 interfaces are now on the 8-port Gig-E switch.<br>
Additionally, you have this newly acquired, SCSI-disk-equipped file server<br>
that is on this same Gig-E switch, and all of this constitutes a single<br>
broadcast domain which houses only the 192.168.x.x subnet.<br>
<br>
BTW, which specific 192.168.x.x subnet are you using--is it <a href="http://192.168.251.0" target="_blank">192.168.251.0</a>,<br>
<a href="http://192.168.33.160" target="_blank">192.168.33.160</a>, <a href="http://192.168.2.128" target="_blank">192.168.2.128</a>, etc? I don't see that specified. And what is<br>
the subnet mask?<br>
</blockquote><div><br>I'm in room 202, so my local network is<br>
<br>
<a href="http://192.168.202.1">192.168.202.1</a> = server1 (application server)<br>
<a href="http://192.168.202.2">192.168.202.2</a> = server2 (application server)<br>
<a href="http://192.168.202.3">192.168.202.3</a> = server3 (file server with /home which is NFS mounted to server1 and server2)<br>
<a href="http://192.168.202.101">192.168.202.101</a> - 130 = the thirty thin clients (assigned by MAC address so I know the IP of each client)<br>
<br>I'm not sure what the subnet mask is set to (and I actually don't know what it's used for, so guidance would be appreciated if there a particular setting that would be useful). I think it's <a href="http://255.255.255.0">255.255.255.0</a>, but I'd have to check to be sure.<br>
<br>
server1 and server2 also have separate NICs that plug into the school
network, get an IP using DHCP and are what we use to access the wider
internet. <br><br></div><blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;">Finally, you have this 8-port Gig-E switch uplinked to a Gig-E port on the two<br>
switches in the lab (another, separate room).<br>
<br>
Is all of this correct, or am I misunderstanding something here.</blockquote><div><br>Correct. Actually, servers 1, 2, and 3 are in a storage closet in my room so they can be behind a locked door and the thin clients are in the room proper. The 8-port gig switch is in the closet with the servers and the 2 24-port switches with 2 gig ports each are in the room.<br>
<br>Sorry I wasn't more clear in the earlier post,<br>Todd<br></div></div></div>
