Another year has passed, and much has happened.

From my event notification framework a web server has risen. I named it gatling because it was designed to serve many small requests. gatling was meant not only as web server, but as generic file server. The idea is: you go somewhere, want to give someone some files, and you just go to the directory with the file and start gatling. gatling than exports the files using as many protocols as possible. So far only HTTP and FTP are actually implemented, and HTTPS. But SMB and NFS are planned. Both protocols are unfortunately very ugly and need more management infrastructure than HTTP and FTP.

I also wrote an anti-spam patch for qmail, find it at www.fefe.de/qmail/. It checks whether envelope sender addresses can be replied to, whether there is some known open proxy or relay on the connecting IP, and some other stuff. Surprisingly effective.

I started writing some ACL infrastructure for tinyldap. Some interesting questions pose themselves. What parameters do you allow for rule parametrization? Only by DN? From the qmail anti-spam patch I have code to match a string against a known list of (sub-)strings, so I could basically match a dn against an arbitrary list of rules with complexity bounded by the length of the dn to be checked, not by the number of rules. However, the more I think about it, the more I think rules should not be restricted to DNs. It should be possible to, for example, match by objectClass. Some further thought is needed on this.

Oh, and I finally bought myself that Athlon 64 I was talking about in the last entry. Surprisingly it is much less noisy than my last system. I watched out for quiet components without compromising on performance, and it is possible. Now that my computer is so quiet, I start to notice how noisy the rest of my environment is :-)
