That sounds like it might be useful. --MCV.

HOWTO debug Ubuntu boot hang

by Andy Stewart

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

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

Anyone going to this that I could please carpool with (I live in Faraday Hall on WPI campus)? I do enjoy walking, but a 4 mile round trip at night sounds unfun.
