Rsync Backup vom Mac zum Linux Server

Mounten des Linux Shares

Nicht vergessen, vorher ~/mnt/tux/joerg Verzeichnis anzulegen

mount -t smbfs //joerg@tux/joerg ~/mnt/tux/joerg

Danach mit Rsync kopieren

sync -rca -verbose -h ~/Pictures/ ~/mnt/tux/joerg/Backups/macbook/Pictures/

Wenn alles geklappt hat, noch den –delete  Befehl hinzufügen. Dieser löscht Dateien im Ziel, die es in der Quelle nicht mehr gibt.

no-ip – self made script

Sometimes my DSL Modem (that has a build in dyndns Client) hangs, and it stops updating
the Server.

I have some notes on my Atom based Linux Server at home and it bugs me if i can’t connect via
ssh from the office.

I wrote a script to mail me the new public ip address as soon as it is changing.
If you have a linux pc/server at home you can do the following by yourself:

put the following php script to your webserver – give it a fancy name like “myip.php”
<blockquote>&lt;? echo $_SERVER[‘REMOTE_ADDR’] ?&gt;</blockquote>
Start the following  script
<blockquote>crontab -l

# m h  dom mon dow   command
0   *   *   *  *    ~/bin/update_ip/;/dev/null 2&gt;&amp;1

on your local linux server:

cd ~/bin/update_ip

LAST_IP=`cat .last_ip`
IP=`curl -s -o – http://mywebserver/myip.php`
echo “last IP : $LAST_IP – new IP: $IP”
if [ $LAST_IP = $IP ];
echo `date +%d.%m.%y-%R` “ip unchanged”
echo “new ip: $IP”
cat .last_ip | mailx -s “New-IP $IP” MAILADR
echo “$IP” &gt; .last_ip
echo `date +%d.%m.%y-%R` “new IP :$IP” &gt;&gt;ip.log

Grub2 Default boot configuration on Ubuntu 9.10

GRUB 2 is the new default boot loader for Ubuntu 9.10. If you would like to change if your pc boots either Ubuntu or Windows by default you have to do the following:

Get an overview of menuentries in /boot/grub/grub.cfg

joerg@phenom:~$ grep “menuentry” /boot/grub/grub.cfg
menuentry “Ubuntu, Linux 2.6.31-20-generic-pae” {
menuentry “Ubuntu, Linux 2.6.31-20-generic-pae (recovery mode)” {
menuentry “Ubuntu, Linux 2.6.31-19-generic-pae” {
menuentry “Ubuntu, Linux 2.6.31-19-generic-pae (recovery mode)” {
menuentry “Ubuntu, Linux 2.6.31-17-generic-pae” {
menuentry “Ubuntu, Linux 2.6.31-17-generic-pae (recovery mode)” {
menuentry “Ubuntu, Linux 2.6.31-16-generic-pae” {
menuentry “Ubuntu, Linux 2.6.31-16-generic-pae (recovery mode)” {
menuentry “Memory test (memtest86+)” {
menuentry “Memory test (memtest86+, serial console 115200)” {
menuentry “Windows 7 (loader) (on /dev/sda1)” {

The first entry should be used as the standard.

Edit /etc/default/grub

sudo emacs /etc/default/grub

Search for GRUB_DEFAULT and change it to 0


If you would like to use Windows 7 by default the parameter in this example is 10 instead.

Save the file and update the configuration with

joerg@phenom:~$ sudo update-grub
[sudo] password for joerg:
