Bootscreen hangs after update from Fedora 10 to 11

I just made an DVD based update from Fedora 10 to 11. After the first boot I was able to login and start an update of all packages (about 2GB).

But at the next boot sequence the pylmouth screen hanged and GDM did not start up. Interestingly enough if I switched fast enough to the boot console with ESC, GDM startet flawless.

After investigating for a while I found out that the following line in /etc/X11/prefdm caused the hang problem:

/usr/bin/plymouth quit $quit_arg

I fixed (by meaning of workaround) the problem by completely disabling starting plymouthd at all. To do so just remove the rhgb option in the appropriate kernel line in /boot/grub/grub.conf.

Check email addresses on SMTP level

New tool smtpcheckaddresses – it checks given email addresses on SMTP level.

The intended use is to validate a MX email server configuration when it comes to email addresses / domains. E.g. during a migration just before going in production one might to check that all configured email address are accepted
and not bouncing.

smtpcheckaddresses.py accpepts a list of email addresses in a text file, one line per address. For each address it then opens a connection to a given host and checks the return code for the “RCPT TO” command. If the return code is in the range 200 to 299 the email address is assumed to be "OK".

Additionally when given the -s option it sends a short test email to the addresses so you can check that mails are really delivered locally and not relayed. It is wise to provide also some email addresses which must fail.

smtpcheckaddresses.py was hacked together in about one hour. So don’t expect much error/exception handling. Needless to say that you use it at your own risk.

Lokales git-Projekt auf Gitosis-Server übertragen

Gitosis ist ein Werkzeug, was das öffentliche Hosten von git-Projekten erleichtert. Hier wird beschrieben wie man ein – bisher lokal verwaltetes – Git-Projekt zu gitosis hinzufügt, sodaß es übers Web und über das git-Protokoll per ssh verfügbar ist. Es wird dabei davon ausgegange, daß schon eine funktionierende gitosis-Installation existiert.
