hostapd, ath9k (AR9287) and Could not set interface mon.wlan0 flags: Unknown error 132

Turns out this error message meant, wireless radio is hard blocked by BIOS. So after enabling wireless radio in the BIOS, I now have a working access point.

xbacklight, squeeze and my NC10
March 1st, 2010 :: Permalink

I recently updated my NC10 from lenny to squeeze. After that xbacklight stopped working:

$ xbacklight -set 50
No outputs have backlight property

Looks like the solution is to upgrade to the latest BIOS (11CA, available from samsungpc.com).

I created a FreeDOS USB stick with information available from Smörgåsbord and fdos.org, copied the BIOS to it, bootet from the stick and successfully flashed my NC10.

Now xbacklight works again.

Lenny NetworkManager Patch
October 31st, 2009 :: Permalink

NetworkManager in Lenny writes it’s PID to /etc/resolv.conf:

### BEGIN INFO
#
# Modified_by:  NetworkManager
# Process:      /usr/bin/NetworkManager
# Process_id:   2869
#
### END INFO

This leads to etckeeper displaying a change every reboot:

This patch to the debian package stops NetworkManager from writing the INFO block to /etc/resolv.conf.

Alternatively, there is a backports package for lenny with an updated version of NetworkManager.

Debian with root on LVM on an USB drive
June 2nd, 2008 :: Permalink

I was getting root file system not found errors when booting etch from a USB disk. As it turns out that the boot ramdisk did scan all devices for LVM partitions before USB drive detection was finished.

By adding rootdelay=10 to the kernel boot options the system will wait for ten seconds before activating LVM partitions giving the USB subsystem enough time to activate all devices.

Nokia E61i and exim4
February 29th, 2008 :: Permalink

Debian’s exim4 uses gnutls which has a feature that will not allow my E61i to use STARTTLS (see #438137) . Perhaps stunnel can help here …

Update: To advertise PLAIN authentication with exim4 for connections origination from localhost I used the following statement in my plaintext authentication configuration (broken into several lines for better readability):

server_advertise_condition =
 ${if or
  {
   {!eq{$tls_cipher}{}
  }
  {
   eq{$interface_address}{127.0.0.1}}
  }
  {yes}{no}
 }

That way plaintext auhentication is allowed for TLS sessions or unencrypted sessions originating from localhost.

Using stunnel and a default ssmtp configuration I can now send mails from my mobile phone.

Thunderbird 2.0 and Enigmail
August 6th, 2007 :: Permalink

After my upgrade to Thunderbird / Iceweasel 2.0 Enigmail was no longer working (see 427591). Seems like something mixed up the versions of installed add-ons. I fixed it by removing Enigmail, starting and stopping Thunderbird and reinstalling Enigmail.

Iceweasel and Scalix
January 26th, 2007 :: Permalink

The webmail frontend of Scalix only supports certain browser types which it checks using the User Agent string supplied by the client. Due to debians move to iceweasel this fails.

With the help of a plugin called User Agent Switcher you can use these settings to make things work.

Firefox 2 and tabs
December 4th, 2006 :: Permalink

And again an upgrade changed the UI. Each tab has its own close button, the one on the far right, closing the active tab is gone. If you like me liked the old behaviour better go to about:config and change browser.tabs.closeButtons to 3.

For more helpfull hints go to lifehacker.com

Update: It seems like there will be more options I’ll tweak, for example set network.dns.disableIPv6 to false, network.protocol-handler.external.mailto to true and network.protocol-handler.app.mailto to icedove
