red spdif light always on on macbook 4,1 with Linux

Posted on December 25, 2011 by admin

I’ve been using debian for a while on my macbook 4,1 and the spdif light stays always on. This is disturbing.
As root, I used amixer set IEC958 off to shut the damn red ligh off.

Good Luck!

ssh over a non standard port

Posted on November 25, 2011 by admin

if you have servers with non standard ports for ssh, you can
a) ssh -p 2009 user@machine
scp -P 2009 …

b) edit your ~/.ssh/config

Host www.example.com
Port 50002

then, just ssh user@machine will work
