Gnome15 Russo79 project site offline

At the moment the server from Russo79 (https://projects.russo79.com/projects/gnome15) for the gnome15 project is offline.
That’s why I decided to publish and upload the gnome15 files I’ve found. I hope its useful for somebody…

gnome15-0.9.7.tar.gz
gnome15-driver-g15direct-0.9.8-1-any.pkg.tar.xz
gnome15-driver-kernel-0.9.8-1-any.pkg.tar.xz
gnome15_debs.tar.gz for Ubuntu/Debian
lg4l-gnome15-0.14-11-x86_64.pkg.tar.xz
pyinputevent-0.1c.tar.gz

If you are building gnome15 on Gentoo Linux, just disable the cairo USE Flag because I didn’t found the required file named cairoplot-gnome15-1.1b.tar.gz

Join #gnome15 channel on irc.freenode.org for any support

Connect to Remote Database with PhpMyAdmin

Posted on by

on Database Server:
apt-get install mysql-server mysql-client

Backup original configuration:
cp /etc/mysql/my.cnf /etc/mysql/my.cnf_orig

Let mysql server listen on all interfaces:
grep -l bind-address /etc/mysql/my.cnf | xargs sed -i -e 's/bind-address/#bind-address/'

Restart mysql server
/etc/init.d/mysql restart

Check if MySQL binds on every interface
netstat -tap

it should look like this:
tcp 0 0 *:mysql *:* LISTEN 2487/mysqld

Now give root user logon permission from Webserver where phpmyadmin is running
mysql -u root -p
mysql> use mysql;
mysql> update user set host=’WEBSERVER-IP’ where host=’127.0.0.1′ and user=’root’;
mysql> flush privileges;

Restart mysql server
/etc/init.d/mysql restart

On Webserver:
apt-get install apache2 php5 phpmyadmin

Edit /etc/phpmyadmin/config-db.php and set the variables
$dbuser='root';
$dbpass='R00tPassW0rd';
$dbname='mysql';
$dbserver='DBSERVER-IP';
$dbport=''; // leave blank if mysql runs on default port

Open your Browser and point to http://yourwebserver/phpmyadmin

Xen: Device xxx (x) could not be connected. Failed to find an unused loop device

Posted on by

If you are using Xen and get an error Device xxxxx (xxx) could not be connected. Failed to find an unused loop device when you try to create a guest. This is because you are out of loop devices.

Run this on command line:
echo "options loop max_loop=32" > /etc/modprobe.d/xen

With the value 32 you are able to run 16 Guests on your host, assuming you aren’t using loop devices for other purposes. Use a number suitable for your needs.

Shutdown your guests and run this on command line:
rmmod loop && modprobe loop

Show all loop devices:
ls -l /dev/ | grep loop

Kubuntu 11.04 install Kernel 3.0.1

Kernel version 3.0.1 stable was just released a week ago. I’m a lazy guy, so I install the precompiled .deb packages.

Get the linux-headers-*-all.deb, linux-headers-*-generic-*.deb, and finally linux-image-*.deb from http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.0.1-oneiric/
Install the .deb Packages in this Order:
dpkg -i linux-headers-*-all.deb
dpkg -i linux-headers-*-generic-*.deb
dpkg -i linux-image-*.deb

Restart your machine, enter the grub menu by typing shift and boot the new kernel. Its possible that u get in trouble while booting the new kernel – just restart and take an older one. Remove linux-headers-3 and linux-image-3 if it didn’t work.

Maybe u need module-init-tools 3.13 where u can get here https://launchpad.net/ubuntu/oneiric/amd64/module-init-tools/3.13-1ubuntu1

Other precompiled Kernel versions http://kernel.ubuntu.com/~kernel-ppa/mainline/

Update ProFTPd to 1.3.3d

Posted on by

Use the newest ProFTPd Version! Compilation for 1.3.3e is the same as for 1.3.3d

Cause of some security issues I’ve decided to upgrade my ProFTPd Service from 1.3.1 to 1.3.3d.

Do a Backup of your current proftpd configuration Directory /etc/proftpd
cp -rfp /etc/proftpd /var/backups/etc/

Then purge the actual proftpd installation
apt-get purge proftpd-basic proftpd-mod-mysql

I’m running proftpd with virtual users on a mysql database with mod_quota, so we have to install the needed libraries for the compilation of the proftpd.

apt-get install libssl-dev libmysqlclient-dev libmysqlclient15-dev libwrap0-dev

get the stable and newest version of proftpd
cd /tmp
wget ftp://ftp1.at.proftpd.org/ProFTPD/distrib/source/proftpd-1.3.3d.tar.gz
tar -xf proftpd-1.3.3d.tar.gz
cd proftpd-1.3.3d.tar.gz

at this point, we’re beginning with the compilation of the proftpd version 1.3.3d. Copy the content of this file in your command line and press enter. U see, that it generates a run.sh file. Run chmod 777 on run.sh

Now run it:
./run.sh

after run.sh has finished, go on with make…
make

if there were no errors, add the user proftpd and then install it
useradd proftpd
make install

if the install has finished, copy the content of this file to /etc/default/proftpd

Cause we used the same configurations like the official Debian package, we can now use their init script.
copy the content of this file to /etc/init.d/proftpd and make it runnable (chmod 755 /etc/init.d/proftpd)

copy the backup from /var/backups/etc/proftpd back to /etc/proftpd and try to start the service.

Post your log files, if your proftpd won’t start.

Windows Server 2008 – Changing RDP Port

Posted on by

Open the Registry Editor

Go to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Terminal Server\WinStations\RDP-Tcp

Open PortNumber, switch to dezimal and change the port.

Click ok and close the registry editor.
By the way: U have to add a Firewall Rule for the new port to Windows Firewall…

I believe, following pictures are self explained…

now you have to restart the server or restart the “Remotedesktopservices” under the Windows Services but befor u test it: You should have physic access to the server, if something went wrong!
If you don’t have this option, install TeamViewer or something like that.. so u could return the changes in the registry.

If it works, deactivate the old RDP Firewall Rule in the Windows Firewall.
