If it's waiting for /dev/sdb1 to show up, or a specific UUID. Maybe comment out anything not required for boot. Also, if you're at the console, comment out your whole /etc/network/interfaces and see if that helps. Ubuntu often waits on block devices and network, so it could be either of those.

HOWTO debug Ubuntu boot hang
by Andy Stewart March 14, 2014

March 14, 2014

HI guys, I've got a version of Ubuntu 13.10 in my Virtualbox OSE virtual computer. It hangs very early in the boot. GRUB runs and the boot starts. In /var/log/boot.log, I see the same messages as I see on the screen. I have to press ESC to see the text while the computer boots. There are perhaps 3 or 4 "Starting <service>....OK" messages, and that is all. I never get a chance to log in. The problem I have is that I don't know in which order the boot scripts are supposed to run. With the "old" initscripts, one would see Snn<script> or Knn<script> and the "nn" would be the number representing the order in which the scripts are "S"tarted or "K"illed. That isn't the case here. I've found the boot scripts in /etc/init/*.conf so I can match boot messages to scripts. However, I'm unable to determine which script got stuck since I don't know the order of execution. My version of 13.10 is customized, not stock, so I can't compare to a known good. Any ideas would be greatly appreciated. Thanks!

Rancid and Quagga
by Eric Martin March 8, 2014

March 8, 2014

Hi All, I recently fired up a few FreeBSD routers using Quagga, and today I went to configure RANCID but I'm having some troubles. RANCID is working fine for my Juniper gear, my Cisco gear and even my APC stuff but I can't get it to work for quagga. I run zrancid (for zebra stuff) and it just hangs. When you add -d you can see that it's asking for show version and write term, but it still hangs. When I copy / paste the commands and run them by hand with clogin, I see it login but it just hangs after terminal length 0 When I login via ssh with the same command line that clogin passes, terminal length 0 works fine and so do the rest of the commands. I'm stumped, does anybody have any ideas? This however does work for my CentOS servers running quagga. I'm using Quagga 0.99.22.3, and Rancid 2.3.6, which is the most recent RANCID version on CentOS and the most recent Quagga on FreeBSD. ~rancid/.cloginrc: add method *.example.net ssh add autoenable *.example.net {1} add user *.example.net rancid add password *.example.net {} (I'm using ssh keys and it's called id_rsa so that works fine). router.db: ur01.example.net:zebra:up ns1.example.net:zebra:up Thanks in advance, -- Eric Martin

Announce: UPDATE: WLUG Meeting Thu 2/20 7PM: Software Defined Radio
by Chuck Anderson Feb. 22, 2014

Feb. 22, 2014

Hi folks, Due to the weather this week, I've rescheduled this month's WLUG meeting for the following week, Thursday, February 20 at 7:00 PM, in the WPI Campus Center, Hagglund Room 301. Our speaker this month will be Andy Stewart, who founded WLUG in 1997 and now runs the Chelmsford Linux Meetup. Andy plans to talk about software defined radio on Linux, and with luck, do a live demonstration of gqrx: http://gqrx.dk/ If there is time, Andy *might* be able to show something related to the GNU Radio Companion, where one can build a software defined radio just by drawing the blocks and connecting them with lines. Thursday, February 20, 7:00 - 9:00 PM WPI Campus Center, Hagglund Room 301 This room is the one across the hall from our usual room, and is where we had the meeting with Jim Getty's on Bufferbloat. After the meeting, we will go out for pizza. See you there, Chuck President, Worcester Linux Users' Group http://www.wlug.org/
