How to export your PuTTY sessions in Windows

Open the registry editor. Navigate to

HKEY_CURRENT_USER\Software\SimonTatham

Right click SimonTatham and export it. Open the registry file to import the sessions.

no exec line in the session file: xfce4

After upgrading an Xubuntu 8.10 system to 9.04 xfce may no longer start properly. If you get the message:

no exec line in the session file: xfce4

In the failsafe terminal, type nano .dmrc
Change Session=xfce4 to Session=xfce

Restart the machine and xfce should start properly. To restart X without restarting the whole system, do sudo /etc/init.d/gdm stop. Switch to another terminal by doing alt+F2, login and then do sudo /etc/init.d/gdm start.

Ubuntu equivalent of rc-update

The Ubuntu equivalent of Gentoo's rc-update is update-rc.d

Gentoo example:

rc-update add ssh default

Ubuntu example:

update-rc.d ssh defaults

dnsstuff.com alternative

dnsstuff.com is not what is used to be, you pretty much have to pay to do anything. iptools.com does pretty much what dnsstuff.com used to do for free.
