Trey, I found this, looks like you are right on the money!
Changing the IP of your LTSP server At some point in time, it may become necessary to change the IP address of your LTSP server. Normally this does not present an issue, but LTSP servers and clients communicate over an encrypted channel and require all SSL certificates to be updated. Without this update, no LTSP clients will be able to log in. This is done by simply opening a terminal and running the following command. sudo ltsp-update-sshkeys You should see output similar to the following, and your clients will now be able to log in again. p...@edubuntu:~$ sudo ltsp-update-sshkeys # Creating dsa-hostkey for edubuntu # Creating rsa-hostkey for edubuntu # Creating dsa-hostkey for 172.29.103.77 # Creating rsa-hostkey for 172.29.103.77 This workstation isn't authorized to connect to server error message on client, please run commands sudo ltsp-update-sshkeys and sudo ltsp-update-image (in this order) reference: https://bugs.launchpad.net/ubuntu/+source/ltsp/+bug/144296 Scott -------- Original Message -------- Subject: Re: [Ltsp-discuss] Login Problem From: thunsuc...@cnc-usa.com To: ltsp-discuss@lists.sourceforge.net Date: 03/01/2010 09:51 PM > Scott, > > Are LanA and LanB in 2 different subnets?
