Sysadmin adventures

Well, its been a while since I dirtied my hands in the sysadmin forays. I was wondering why my system was not accepting mail for a domain that clearly pointed to it. Running host just pointed to the mailserver correctly, but when I ran it on the mailserver, there was an IP address mismatch. Thinking back a little, it seems that there was an IP change, just something I’d forgotten about. Oh how the great DNS, comes to bite you in the behind.

MediaWiki these days likes PHP 5 (5.1 being preferred). I’ve discovered why Red Hat Enterprise Linux 4 might suck – they only ship PHP 4.3.9, which is nowhere near as adequate for modern applications. So if I were a corporation and wanted to run the latest greatest Mediawiki on my corporate wiki, I’d be in a bind if I’m on RHEL4. Luckily, this is where the centosplus repository comes into active play – its got a modern PHP, and modern databases.

I’ve gotten out of the Planet game. After running Planet MyOSS for a countless number of years, I’ve just decided that the final migration should happen today – and it did thanks to a Redirect 301 / http://planet.foss.org.my/. Update your bookmarks, feed readers, etc.. as Planet MyOSS now resides at: http://planet.foss.org.my/. (except I checked it just now, and foss.org.my was down… it seems to be regularly down, why?)

Those having to deal with MYNIC, keep in mind that their online forms differ if you’re logging in as the Administrative or Technical contact (the latter is where you get to change DNS servers). And no, its not instant, they say its a 24-hr waiting period.

Back to RHEL/Centos. Why does the Linux Standards Base (LSB) stipulate that servers need to have CUPS installed, to be LSB compliant? I’ll probably talk more about the recent cleanups I’ve been doing at another stage.
