So far, Zimbra is impressive!

May 13th, 2008 Jacken No comments

since using my new mail system Zimbra, I Must say I’m very impressed. The web client is actually so good that I now use it more than Apples built in mail that I’ve used forever. But until it’s time to migrate this setup to work I need to run it a bit more and also try to restore a backup. I can’t use the standard backup because thats not included in the open source addition. I also need to read up on the performance of it. Using it at home with 5 users really does not give a good indication on how much processing power needed for 45 users. Theres also two ways of doing the install, one is to install everything on one machine, another to split up the work to several servers. It does seem to be a problem to upgrade a single server to multi-server so I need to get it right from the beginning.

Speedup of the Swedish 3G provider tre

May 8th, 2008 Jacken No comments

After getting a 3G connection on my new toy, I noticed that connecting to a site when browsing the web could take a long time, but as soon as it gets to the page it’s fast. Typical behavior of a slow DNS server. So after changing my /etc/resolv.conf file to use the OpenDNS servers instead, the increase in speed is incredible!

The eee PC use resolvconfig, so to make the changes permanent you need to go to the directory

sudo pico /etc/resolvconf/resolv.conf.d/base

Add these two lines:

nameserver 208.67.222.222
nameserver 208.67.220.220

to the file and save.

My guess is that Tre has a lot of customers that gets annoyed of the slow speed, and all the provider needs to do is to upgrade their dns servers. Or maybe tip their customer of a better alternative. Go figure…

Good timing…

i’ve spent this weekend building and installing a new web/mailserver. My decision to go with Zimbra doesn’t feel so risky, because Microsoft gave up on their idea of a Yahoo! takeover.

The only thing I can say is: Yahoo!

Getting tre.se 3G USB modem to work with Asus Eee pc 900 linux

April 30th, 2008 Jacken No comments

I just got my Asus eee pc 900 from Taiwan. Here’s a quick tip for other users of tre.se 3G wireless broadband. When connecting the Huwei USB modem, the Asus Mobile Phone tool automatically starts. But the supplied carriers are only for Taiwan. Select Chungwa and select “Others”. Enter bredband.tre.se in the field. Save the settings and your up and running!

Update: There’s actually an option to select tre.se when creating a new connection.
