Re: [Wlug] HOWTO debug Ubuntu boot hang

Andy> I've got a version of Ubuntu 13.10 in my Virtualbox OSE virtual Andy> computer. It hangs very early in the boot. GRUB runs and the Andy> boot starts. I've moved to Linux Mint myself, but it's based on Ubuntu and I've noticed that my main desktop, which NFS mounts home dirs and other stuff, takes *forever* to actually boot not. There's something in the setup which hangs for five minutes or so (not sure, I just walk away right now cause I rarely reboot the box...) before it continues. Have you just let the boot sit there to see if it ever finishes? I've been meaning to turn on verbose debugging to try and figure out what's going on too, but it's a low priority.

Have you looked in /var/log/upstart as well? You might be able to also setup your system so that init (upstart) is started with the -v option to increase verbosity.

That isn't the case here. They're supposed to run according to events, not any particular order. The idea is that as things become ready, the next step can fire off more quickly, without the system getting stuck behind some hanging process. Good luck! John P.S. Another idea might be to try and boot a default 13.10 install in another VM and see how that looks in the console. It should be similiar at least, if not fairly identical. John

The FreeBSD folks eventually remedied the problem ("SYNCDHCP" setting for network interfaces) but my initial "fix" was to edit the network start script and add a "sleep 5" or "sleep 10" line in there allowing the networking to settle. Other cures have been to insert a ping or a dig call which must succeed, before allowing the boot process to continue. 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 do any video editing? I've tried using pitivi to edit videos. It usually crashed. Recently I tried putting a series of images in and creating a video. I successfully created a video once. Now everytime I seem to create a file without any video content. The video isn't going to be long or good. I was showing my son how lego stop animation is done. I only did a 8 images and they aren't perfectly aligned. I used a small tripod but press the picture button must have moved the camera a bit.

Announce: UPDATE: WLUG Meeting Thu 2/20 7PM: Software Defined Radio

by Chuck Anderson

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/

Sometimes you get burned when the predicted weather fails to materialize, but that's life in New England.
