Adding a non-detected modeline in ubuntu as default

December 16, 2010 Leave a comment

I adapted the procedure I found here to make my old Samsung Syncmaster 192N work at its native resolution. It is running through an old projector on the ceiling, which I’m sure is what is breaking the autodetection.

cvt 1280 1024 75

That returned: # 1280×1024 74.90 Hz (CVT 1.31M4) hsync: 80.30 kHz; pclk: 138.75 MHz
Modeline “1280x1024_75.00”  138.75  1280 1368 1504 1728  1024 1027 1034 1072 -hsync +vsync

Added these lines to /etc/gdm/Init/Default:

xrandr –newmode “1280x1024_75.00”  138.75  1280 1368 1504 1728  1024 1027 1034 1072 -hsync +vsync

xrandr –addmode VGA-0 1280x1024_75.00

xrandr –output VGA-0 –mode 1280x1024_75.00

Now it starts out at the correct resolution at startup, regardless of the state of the projector.

Vmware: “SIOCSIFADDR: No such device eth0″ after cloning

June 20, 2010 Leave a comment

from: http://muffinresearch.co.uk/archives/2008/07/13/vmware-siocsifaddr-no-such-device-eth0-after-cloning/

This is specifically for ubuntu.

sudo mv /etc/udev/rules.d/70-persistent-net.rules /etc/udev/rules.d/70-persistent-net.rules.old
sudo reboot

May need to edit /etc/network/interfaces eth0 or eth1 to match detected adapter, restart the network, and it should be back to normal.

Adding a New Mailnode in Scalix

March 9, 2010 Leave a comment

This needs to be done after adding a mailnode to enable outlook connector and webmail. This was sent to me by Scalix support.

Add the mailnode first within sac.

The rest is done from a terminal.

To get a list of your mailnodes:

omshowmn -m all

The name displayed against two asterisks ** is name of primary mailnode
Replace mailnode with new mailnode name, and primarynode with your primary mailnode name.

omaddbb -s "mailnode"
omdelacln -t b -l ":mailnode" -g admin
omdelacln -t b -l ":mailnode" -g local
omdelacln -t b -l ":mailnode" -g default
omaddacln -t b -l ":mailnode" -g admin -c visible
omaddacln -t b -l ":mailnode" -n "*/mailnode,*,*,*" -c create read subfolder editown deleteall contact visible
omaddacln -t b -l ":mailnode" -n "Proxy-Folder Admin /primarynode/CN=Proxy-Folder Admin" -c create read subfolder editown deleteall contact visible

I did find/replace with a text editor and drag-n-drop into a terminal window. It took longer to type this up!

SSH tunneling with firefox

January 22, 2010 Leave a comment

from a terminal window:

ssh user@<<ssh server>>.com -D 9000

in firefox:

go to preferences:advanced:network:Connection Settings

This will pipe all web traffic through a secure ssh tunnel, and allow access to local web resources from firefox.

Of course you want to disable that firefox setting if you’re not connected to the tunnel.

There is a firefox addon called Quickproxy that allows you to activate/deactivate the proxy settings with a button push:

https://addons.mozilla.org/en-US/firefox/addon/1557/

And sshmenu has a great interface for quickly connecting to remote sites.

sudo apt-get install sshmenu sshmenu-gnome

The ln -s  is necessary due to a change since ipcop v 1.4.18
