port 1 disabled by hub (EMI?), re-enabling and wview weather

Me and a friend recently reinstalled a crashing Windows XP minipc used as weather station with Ubuntu 13.10 server. Since Linux is normally better working than Windows we thought it could be a good move, also because from time to time XP had to be rebooted. We choose wview as management software, as it seems pretty popular.

Sadly the day after installation and configuration we found Ubuntu to be less reliable than before. Well, maybe it wasn’t a Linux fault, it’s probably just more sensitive to some hardware issues. The culprit was found to be EMI (ElectroMagnetic Interference). Syslog showed the following: Continue reading port 1 disabled by hub (EMI?), re-enabling and wview weather

Compiling Zimbra server on Ubuntu 8.04LTS

Last version of Zimbra collaboration, version 6.0.6, had been subject to several delays, which lead to a gap of nearly three weeks since the first proposed release date.┬áThese dates are considered target, thus flexible. Normally, I wouldn’t get crazy about release dates. Yes, while you may wish to get your hands on, because it fixes the most annoying but you ever had, you can wait some more days anyway.

But 6.0.6 had several fixes I really needed at some place. And after the second delay, I decided to try to compile Zimbra from source. Brave you think? Me too…

Convirt: transform a VM from HVM to PV

We recently reinstalled our main server. It’s a Xen 4.0.1 host, based on Debian Squeeze. We don’t have many VM on it, it’s basically to save some power and have a sandbox for some test installations. Can be useful, quite often.

Instead of using plain CLI tools (xen-tools basically), I decided to give a try to one of the most well known interfaces for Xen: Convirt. Formerly xenman, born some years ago, at some time it moved to a commercial software, with open source base. Can be installed on custom host, as in my case, or downloaded as VM appliance!
Beside all considerations, it’s quite cool, even if I find documentation a bit lacking, the forum has some nice people. Not really as much as I’d like, but useful.
