When transfering a harddisk with Ubuntu 10.04 to another machine you’ll end up without a working network connection.
To overcome this you can do:
echo -n > /etc/udev/rules.d/70-persistent-net.rules
echo -n > /lib/udev/rules.d/75-persistent-net-generator.rules
Installing OpenVPN-GUI (openvpn-2.0.9-gui-1.0.3-install.exe in my case) on Windows 7 Pro 32Bit works as usual by running the setup process.
Although the connection will be established you won’t have any routes.
- Download setacl from http://setacl.sourceforge.net
- run setacl -on openvpnservice -ot srv -actn ace -ace “n:Benutzer;p:start_stop”
- by going to Computer/right click/maintenance/user and groups add the desired user to the group Networkconfiguration-Operators (Netwerkkonfigurations-Operatoren)
- in the .ovpn configuration file add the lines
- disable the service openvpngui via msconfig
- change the startlink for OpenVPN-GUI to be run as Administratior
Assuming you have a default installation of Apache 2 and Tomcat 5.5 running on your Ubuntu box.
Like apache on http://hiserver and Tomcat on http://hiserver:8080
Now you want to accces i.e. http://hiserver:8080/baula through apache with http://hiserver/baula

Just some common pitfalls to avoid when setting up BackupPC….
- When doing a backup of a host whose data is mounted using a nfs share then you have to modify the TarClientCmd.
$sshPath -q -x -n -l root $host env LC_ALL=C $tarPath -c -v -f – -C $shareName+ –totals
env LC_ALL=C $tarPath -c -v -f – -C $shareName+ –totals
because ssh doesn’t work when accessing local directories.
- The part env LC_ALL=C is important if you work with a non english locale. Because otherwise the backup gets done but in the end BackuppPc can’t check the result.
- To avoid all sorts of access restrictions run tar as root like
env LC_ALL=C /usr/bin/sudo $tarPath -c -v -f – -C $shareName+ –totals
To make this work start visudo and add the line
backuppc ALL=NOPASSWD: /bin/tar
sudo add-apt-repository ppa:robert-ancell/simple-scan
sudo apt-get update
sudo apt-get install simple-scan
Sometimes programs aren’t used in a way the programmer knows when creating a software. I had the situation that the properties stored in the registry where system wide but I needed different settings for every user.
Well actually not really a problem. (Except if you need to use Windows 7) I located the settings in the registry exported them into a .reg file and a small .cmd batch job should append a user specific setting and start the program.
The only problem is that a line like
resulted in a new line in export.reg with CHINESE CHARACTERS !!!!
But if you take the content of the export.reg and copy it into a NEW file and save it as export.reg then everything works.
PLEASE TELL ME WHAT THE FUCK IS GOING ON HERE !!!!!
Ok, it’s actually only a small problem, but PLEASE tell me the concept behind this – or – oh I understand – there is no concept…..
One of my customers is running a IPCop machine that does all the DHCP/DNS/Gateway stuff on the network. This works on the local 192.168.10.x network.
Recently we added a second internet line for accessing the company’s headquarter. They use the 172.16.x.x network.
route add -net 172.16.0.0 netmask 255.255.0.0 gw 192.168.10.2
does the job.
In order to make that route permanent the above line has to be added to /etc/rc.d/rc.netaddress.up also.
Now every workstation on the local network is capable of accessing the headquarter’s network by IP address. But accessing the headquarter’s network by hostname does NOT work.
The reason is that every DNS request to the domain .headquarter.group gets transferred to the public DNS by IPCop and .group is no valid public TLD.
Using IPCop’s DNS1 / DNS2 settings does not work because the multiple DNS only get asked in case the previous one is unaccessible.
What has to be done is to tell IPCop that he has to use a different DNS once a request concerning .headquarter.group arrives.

There are serveral reports that Firefox (as well as Epiphany) is not able to upload files from a network-share on recent versions of Ubuntu. See Bug #279193 for example.
You can solve this by linking your ~/.gvfs directory to the bookmarks in nautilus.

For some reason it may happen in Ubuntu Lucid (10.04) that your USB storage devices aren’t detected anymore.
The indeed _very_ strange solution is to turn off LEGACY FLOPPY SUPPORT in the BIOS setup. If you don’t have such a setting (i.e like my Dell Precision T3400) and don’t have any floppy drive either then try deactivating everything that refers to floppy drives in the BIOS setup.
A short (one line) script for linux that pings all clients on your network. If using another subnet than 192.168.0 then you have to adjust the numbers.
while [[ $((++i)) -le 254 ]];
do ping -c1 -w1 192.168.0.$i | grep ttl | cut -d " " -f4 | cut -d ":" -f1;
