I wanted to record how much bandwidth is being used during the month. I found these instructions to install vnstat, a traffic monitor.

• open a ssh connection to your router
  • the credentials are the same that you use in the web admin portal
• run the following lines to add the debian repo

  • configure
    set system package repository wheezy components 'main contrib non-free'
    set system package repository wheezy distribution wheezy
    set system package repository wheezy url http://http.us.debian.org/debian
    commit; save; exit

• update cache
  • sudo apt-get update
• install vnstat
  • sudo apt-get install -y vnstat vnstati
    • vnstati is a tool that creates images off of the data
• run vnstat

  • sudo vnstat -i eth0

• run this line to allow vnstat to start after reboot

  • ln -s /etc/init.d/vnstat /config/scripts/post-config.d/vnstat

I installed X2Go yesterday on a Ubuntu server of mine. Of course I didn’t get my configuration right the first time 🙂 but X2Go was working 😉 . Since it was a VPS I just re-installed from scratch. However, I wasn’t able to get my X2Go windows client to work after the re-install. I received something similar to the error below.

Hostkey for server changed. The host key is now xx xx xx xx
The connection is being closed now.

After doing some Google searches I finally found something that kind of helped. They recommend deleting the “.ssh” directory but that didn’t work for me. I had to delete the “known_hosts” file under the directory “C:\Users\XXXX\ssh”, XXXX of course being your username.

You can also edit the file and just delete the line that contains the IP address your trying to connect to.

I am running Windows 7 Professional.
