dbclinton and all, i have good news and bad news.
first, the good news. the one computer that wouldn't connect was a cable issue - the protective cover for the locking pin hit the case before the connector was set in place. after it was set in place, i was able to get into the edubuntu log in screen. also, the switch looks to be working fine. the rest of the news is bad... or should i say leaves room for opportunity. i tried to connect three computers. first, i connected my laptop (toshiba laptop circa 2005) which got me to the boot screen. i logged in with the admin password. the desktop displayed shortly thereafter, however, there was high pitched hum coming from the speakers (a ray gun sound came to mind) and none of the icons did anything. the mouse did move, though. i hate to hold the power button to shut down the laptop. next i tried to boot the computer with the connector problem. again, i was taken to the login screen and entered the admin's login. i was left with a blank screen and a visible mouse pointer. i could move the mouse pointer around with the mouse. i had to manually turn off the computer. the third computer never made it to the login screen. i was left with the monitor flickering in the following repeated sequence - bottom 1/3 of the menu turned greenish, cursor displayed as "x", cursor changed to circle with internal spinner, a quick flash of the ubuntu color with a possible black box flicker that looked to be in the location of the login box and a blank screen. also, i didn't realize the clients would be prompted for a password. how do i set the username and password for the specific clients? any help resolving these issues would be greatly appreciated. tia... ----- Original Message ---- From: dbclinton <[EMAIL PROTECTED]> To: [EMAIL PROTECTED] Cc: EDUBUNTU MAILING LIST <[email protected]> Sent: Tuesday, April 15, 2008 10:51:30 PM Subject: Re: Plan B Edubuntu Terminal Server Install Problem Coincidentally, my first successful thin client connection was with a laptop (a Compaq PIII 1.0 ghz whose BIOS controlled the boot-to-NIC perfectly). Check out the BIOS of some of your clients to see if their boot options include booting to an NIC. Resetting the switch simply involves pulling its adapter plug for a few seconds and letting it start up again. Either it will make a difference immediately or it won't. Not a lot of guessing on that one. Check outputs from /var/log/syslog during client boots to see if your clients are getting IP addresses. This is the beginning of a successful thin client boot on my system: Apr 15 13:13:58 rishon dhcpd: DHCPDISCOVER from 00:50:da:d0:c6:af via eth1 Apr 15 13:13:59 rishon dhcpd: DHCPOFFER on 192.168.0.244 to 00:50:da:d0:c6:af via eth1 Apr 15 13:14:01 rishon dhcpd: DHCPREQUEST for 192.168.0.244 (192.168.0.254) from 00:50:da:d0:c6:af via eth1 Apr 15 13:14:01 rishon dhcpd: DHCPACK on 192.168.0.244 to 00:50:da:d0:c6:af via eth1 Apr 15 13:14:09 rishon dhcpd: DHCPDISCOVER from 00:50:da:d0:c6:af via eth1 "00:50:da:d0:c6:af" is my client's MAC address - the first sing that the computers are at least talking to each other.
