Just a note: Ubuntu updater offers 11.10 final:

I'll try it to see whether it works.

My linux month: Start!

My "day-book" of my Ubuntu experiences as a day-by-day system can be found here:

http://southbrain.com/south/articles/me-and-my-desktop-ubuntu-1104.html

The article will grow and be split in multiple ones.
I will try it.

I'll begin on Wednesday. No more Macintosh, no more Windows - I chose Ubuntu 11.04 on a Fujitsu Siemens Esprimo PC with an Intel Core 2 Duo CPU running at 2,1 GHz. 4 GB RAM and a 500 GB Western Digital Enterprise Storage Hard Disk.

Not an expensive choice - I spent 150 Euros for the old PC, the new RAM and the new hard disk.


Will I be able to work day by day with this machine? Doing business? Watching movies? Playing games? Writing letters? Browsing the Internet? We'll see!

Problem was/is: After upgrading to CentOS 5.6, the ssh server did not start which can be somewhat "embarassing"...















On the console I get the following:

[root@douala pascal]# /etc/init.d/sshd start
Starting sshd: Auto configuration failed
9009:error:0E065068:configuration file routines:STR_COPY:variable has no value:conf_def.c:629:line 228
                                                           [FAILED]
[root@douala pascal]#


Explanation and solution is very simple:


Just a little note: SOGo groupware

| | TrackBacks (0)
If you're looking for an open groupware with a decent web interface including CalDAV support for calendar clients, look at SOGo.

It uses an existing IMAP server for mail and an SQL database for calendar and contact data. A setup with RedHat 5.5 (or CentOS 5.5) works fine (atfer adding the rpmforge and sogo repositories). I am using PostgreSQL as database engine and Cyrus IMAP 2.3.16 as imap mail store. Enterprise directory (and authentification) data is fetched from an LDAP or an SQL data source. It is built with GNUstep and configuration is done as GNUstep defaults (command "defaults").

Firefox 3.5/3.6 and IE 8 are supported for the web frontend.

QLA Linux and RDAC - Sun 6140 Failover

| | Comments (6) | TrackBacks (1)
Accessing a Sun StorageTek 6140 array with multipathing (failover) via Fiberchannel from a Linux host is not so easy (You'll dream about having scsi_vhci MPxIO out of the box in Linux...).

First: The Sun StorageTek 6140 does not support symmetric multipathing - only one path and controller is active for a given volume. When trying to access the volume on another path SCSI errors are the result. So the failover code has to talk to the array if it whishes to change the active path.

Second: Linux (with actual Q-Logic drivers) offer two multipathing strategies and none of them is usable with this Sun arrays:
