Ubuntu: Create own or fix broken samba shared directorys

ubuntu_logoI recently wanted to create a shared folder with the attribute hidden, but did not want to change the /etc/samba/smb.cnf.

So i searched where the shares created by the gnome folder-properties window where saved. The directory is:


This is also the place, where you might fix a broken share by deleting the config file.

Ubuntu: Install on a Disk with less than 4.4 GB (Workaround)

ubuntu_logoI tried to install Ubuntu 11.04 on a 4 GB USB-Stick today, but was failed by the installer who wants at least 4.4 GB free space. This is unnecessary much, because a normal Ubuntu install will stay below 2.5 GB.
I found a "fix" that works like this:

Ubuntu: Booting with "quiet" and "splash" ist faster.

I like to see what is going on when my ubuntu boots, so i disabled "splash" and "quiet" in mit "/etc/default/grub" and updated grub via "update-grub" afterwards as root.
Today i checked how this might slow down the boot process, because of the much output by the kernel. This is my result:

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash" --> 28 Seconds
GRUB_CMDLINE_LINUX_DEFAULT="quiet" --> 32 Seconds
GRUB_CMDLINE_LINUX_DEFAULT="splash" --> 30 Seconds

On my system, "quiet" speeds up booting by 1 or 2 seconds, and "splash" by 2 or 3 seconds.

I might leave both on for faster booting, but i will miss my informative kernel output :(

Sicherheit: Kritische OpenSSL Lücke in Ubuntu

Es wurde ein Sicherheitslücke im neuen Ubuntu Linux 8.04 LTS System gefunden welche durch präparierte Pakete eine Denial of Service Attacke in Programmen die gegen OpenSSL gelinkt sind verursachen kann. Es können aber auch Ruby Scripte genutzt werden um die Attacke durchzuführen. Es ist sowohl ein Denial of Service Angriff möglich, als auch das Einschleusen von Fremdcode welcher dann mit den aktuellen User Rechten ausgeführt wird.

Es wird empfohlen alle betroffenen Systeme mit der OpenSSL Schwachstelle upzudaten: Ubuntu Linux LTS 8.04 und Kubuntu, Edubuntu, and Xubuntu.

Das Updaten geht so:

apt-get update
apt-get upgrade

Damit die Änderungen auch übernommen werden ein Neustart:

sudo reboot
