Just a short note on getting a minimal Asterisk environment installed on current versions of Debian and Ubuntu:
aptitude install asterisk
m-a a-i zaptel
/etc/modules so it gets loaded when the system starts.
m-a command is not found, install the
I’ve been always a fan of the robust upgrade procedure documented in the Debian release notes, which has worked without problems even over ssh to remote machines. This has made upgrading very painless (at least since sarge — I haven’t used Debian actively longer than that).
Yesterday I ran into a problem, though, which was only saved by having remote console access. I have a system with a slightly more complicated disk setup: it has two SCSI disks running as a RAID 1 array using md and lvm. Upon rebooting after the upgrade, the system didn’t reappear on the network. What I found on the console was the initramfs panic shell: the root file system had not been found. Rebooting the old etch kernel worked fine.
The workaround proved to be very simple, once I distilled it from the search engine results. Just add
rootdelay=10 to the kernel options in the bootloader. I’m using GRUB so this translates to editing the
kopt line in
/boot/grub/menu.lst and running
I had also added
/etc/initramfs-tools and regenerated the initrd, but that (alone) didn’t help. I’m not even sure it is needed at all — it might already be included anyway when using
I’m following most web sites with Google Reader these days. With some sites I’ve noticed that images don’t show up in the reader interface. I figured this would be because the site is attempting to protect against hot-linking to its resources — and it seems I was right.
The quick fix with Firefox is to disable sending referer-information for inlined images. You can do this in about:config by changing the value of network.http.sendRefererHeader to 1.
While there, I also changed network.http.sendSecureXSiteReferrer to false. This prevents referer-information from being sent between different secure sites.
