3Com has recently introduced a new networking platform called “Open Service Networking” - or “3Com|ON” for short. It introduces the capability for network routers to run applications which previously required a separate device. One of the first blades to be available was the mebeliOpen Services Networking Module running a version of Linux (OSN|OS with kernel 2.6.9). This module enables open source applications such as MRTG, Nagios and Ntop to run directly on the router.
The list of partners is already quite extensive, but the one that stands out is VMware. After doing a bit of digging I discovered that VMware Server is currently in the 3Com|ON Solutions lab, so this may mean we will see a router blade containing VMware’s virtualization technology in the near future.
I was a bit disappointed though to find out that you can not use storage vmotion from the Virtual Infrastructure Client. Instead you can either install the VI Remote Client utilities on your workstation, or deploy the VI Remote Client appliance (which is a doddle with the new appliance importer). Once you have the client tools, it is simply a case of running svmotion.pl --interactive and responding to the prompts. The good news is that it just worked with no hiccups.

It only took a year, but at last I was able to apply and receive a signed certificate using the JANET Server Certificate Service. It was also the first certificate I had installed on a Microsoft Exchange 2007 server. The actually process I found quick and easy, and took less then 24 hours before I had the signed certificate installed. The only minor hiccup I encountered was a printing error on the signed request document which meant that the subject name was not visible. Oh, and I needed to install the Cybertrust Educational CA certificate in the correct certificate store (Machine->Intermediate Certification Authorities.) See for your self at http://212.219.188.74/ (it will redirect to the SSL website).

As of this morning, centos.org is unavailable due to a DNS problem. The problem seems to be with the name servers for org. as they have no NS records for centos.org. In the mean time, there is a mirror available here, and a list of mirror servers here.

I recently added some Dell PowerEdge 1955s into a chassis alongside the original 1855 blades. Since the two have different CPUs, you will need to adjust the CPU masking of your guests. This will let you vmotion 32bit guests between them, but not 64bit guests, since these are not supported on the 1855 servers.
Change the level 1 eax register mask to the following:- ---- ---- ---- ---- ---- XXXX ---- ----
Change the level 1 ecx register mask to the following:- ---- ---- ---- -0-- 0-0- --0- -R0- ----
It seems that the site has been inaccessible for a few days owing to a disk corruption. I have had to rebuild the server from scratch and restore the site from backups. It was a good opportunity to ditch Fedora for CentOS anyway. The outage was slightly extended due to the fact that I have been suffering from a cold for a few days and I would not have been able to do anything over the weekend anyway. Sorry!
I am in the process of setting up a new domain, and one of the things I am currently stuck with is redirecting the home folder on Windows Vista clients. Now, on Windows XP, all of the folder redirections work fine. However, Vista throws up the error:-
Failed to apply policy and redirect folder “Documents” to \\[domain]\dfs\Home\Staff\[username].
Redirection options=9219.
The following error occurred: “Can not redirect descendant into parent”.
Error details: “The specified path is invalid.”.
