X2Go – Hostkey for server changed.

Published by admin on June 28, 2012

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.

Playing around with VMware ESXi 5

Published by admin on June 22, 2012

I just started playing around with VMware ESXi 5 which appears to be free! Yey! 🙂

You can download it at the VMware website, http://www.vmware.com/products/vsphere-hypervisor/overview.html. Don’t forget to apply for the license which is free, otherwise you get a 60-day trial.

The reason I choose VMware ESXi was because I’m pretty familiar with VMware. I’ve had their workstation as long as I can remember. I actually had a license for both Linux and windows at one point. And umm… because that’s really the only one I could use on my server, hardware restraints.  🙂

There are a few other free virtualization software packages.

  • Citrix XenServer
  • Proxmox (open source)  – does KVM and OpenVZ
  • Virtuozzo
  • VMware ESXi
