KMail, multiple SMTP servers and the alternative sendmail
KMail has always problems with multiple smtp servers. As a solution I installed sendmail. Then I just created a new outgoing mailserver and selected the sendmail option. No further configuration was necessary and it seems to work.
EMBOSS and GCK for the assembly and documentation of construct sequences
I am trying to use EMBOSS for the assembly of vector sequences. Long time ago, I used the CGC seqed program for this purpose and at the moment I use the Gene Construction Kit. EMBOSS doesn't have a straight equivalent for seqed and one has to use a bunch of other tools to replace its functionality. Look at this comparison between CGC and EMBOSS.
Manually uncompressing backup files creating by BackupPC (Zzzz)
The perl script /usr/local/backuppc/bin/BackupPC_zcat does it, but you need BackupPC installed for this purpose. There is a standalone frontend for the compression libraries available called Zzzz... made by the same guy who is behind mplayer.
Changing runlevels ob the fly using telinit (without rebooting)
Usually you change the default runlevel by editing /etc/inittab. However, sometimes you boot into runlevel 3 (e.g. by selecting safe mode from the grub menu) and then want to change to runlevel 5. This you accomplish with the command: telinit 5
Start netatalk as system service during bootup on Suse Linux 9
I am missing from Suse Linux 9 a nice GUI that collects ALL system services with the options "start", "stop" and "start on every system boot". RedHat 9 has something like that. There is Yast2, but under the services, netatalk is not even listed. To boot netatalk during system boot, I just create manually a link: cd /etc/init.d/rc5.d sudo ln -s ../atalk S22atalk After rebooting (and to my surprise) my computer froze. No Ctrl-Alt-F2, no access via ssh; the only rescue being the physical reboot button button (something I am only used to from my Macintosh times).
