On a personal note.. My company fortrabbit proudly launched our new online billing tool. Granted, this is not the first, but in Germany, the market is quite new. The software is implemented in our MISH system, which is a perl/catalyst application running also our hosting control panel. Speaking of which, our hosting pricing is based [...]

I am developing a new mail server anti spam solution called decency.  It is a one-in-all solution attempt implementing a policy server (postfix policies), a content filter and a log parser. All three of them run in separate servers but are designed to communicate with each other to improve the spam detection rate a lot. [...]

Once in a while i have to have new software. On a recent research about using VCS on NAS devices i came across Redmine (cause they talk about GIT and Mercurial a lot). We have used Mantis for at least two years and were never really satisfied with it – don’t get me wrong, it [...]

In our Mailservers (Postfix) we use a lot of policy-servers, which are custom perl servers, eg granting sender permissions to external mailservers or building live-statistics of mail throughput. However, i recently ran into some problems starting one of those which uses a berkley database backend (aka bdb via BerkleyDB and BerkeleyDB::Env with DB_INIT_MPOOL from CPAN). [...]

Jüngst versuche ich mal wieder ein wenig Memory Leaks in unserer Applikation zu finden. Es ist zwar nicht so, dass die Server “explodieren”, aber bei einem der beiden ist letzthin über 24Std doch schon ein starker Anstieg (~75%) des RAM Verbrauchs nach Start der Prozesse zu verzeichnen. Das lasse ich nun schon seit einigen Wochen [...]

Endlich komme ich mal wieder dazu etwas zu schreiben. Unsere Hostingsoftware kontrolliert alle Serversysteme uA über simple Kommandoabgabe per SSH .. quasi SSH PUSH. Unter Perl gibt es dafür drei gängige Wege: Net::SSH Net::SSH2 Net::SSH::Expect Net::SSH::Perl Da ich bisher gute Erfahrungen mit Net::SSH::Perl gesammelt hatte, entschied ich damals auch wieder dafür. Jetzt kam ich aber [...]
