There is no public key available for the following key IDs

when trying to apt-get update i got this error message :-
W: There is no public key available for the following key IDs xxxxxxxxxxxx
this problem was caused by change of gpg key used by ftpmaster on Debian official repository servers. Google gave me some information and I found some fix which works fine for me:
error :
W: There is no public key available for the following key IDs:
9AA38DCD5512345678
W: GPG error:
http://ftp.us.debian.org etch Release: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 9AA38DCD5512345678
W: You may want to run apt-get update to correct these problems
DO!
find out invalid key. its 8 digits string from the right in my case my key id is 12345678
check the key id with
#apt-key list
find out if its there on not. the format should be xxxxx/our-key
if you found one then
#apt-get update
if not?
#gpg -a --export (error keyid here) | sudo apt-key add -
#apt-key update
#apt-key list
then try to apt-get update again
its work for me..

Using Mytop to monitor Mysql Server

Debian 5.x ( Lenny ) and Nvidia

just want to share..

Lenny just about confusing me a little bit when trying to configure X. i found no Module section on xorg.conf and no driver for VGA device. here what i did..

as root:-

#apt-get install module-assistant nvidia-kernel-common nvidia-xconfig
#m-a auto-install nvidia-kernel${VERSION}-source

then edit xorg.conf but first we make a backup ( always! )

#cd /etc/X11
#cp xorg.conf xorg.conf-old
#pico xorg.conf

put this if not exists

Section "Module"
Load "glx"
EndSection

then put following driver to VGA Device section

Section "Device"
Identifier "Configured Video Device"
Driver "nvidia"
EndSection

now you can restart X. Nvidia logo shown on your screen telling you that you are using nvidia driver
