OpenBSD

It seems that OpenBSD people has then patched cvs vulnerablity, though. In this version, OpenBSD has pf(4) improved a lot!

刚刚揭露的那个TCP漏洞OpenBSD在1999年就修正了……和FreeBSD现在用的方法类似，只是更严厉一些。折服了……

Wietse Venema has released postfix 2.1-RC5 yesterday, and this is expected to be the final Release Candidate of postfix 2.1-RELEASE.

I have turned on several anti-spam settings on beastie.frontfree.net to ease my life. They stand for “most evident spam characters” and hence should not go to the content filtering subsystem and should be directly dropped.

It seems that postfix 2.1-RELEASE will include an amazing feature called “policy server”, which can be used to implement greylisting, a brand new and effective technique to fight against spammers.

Bruce M Simpson has added Daniel Hartmeier to the active committers’ rank. Daniel is from the OpenBSD campaus and is one of the authors of OpenBSD’s stateful firewall, pf(4).

I’m still working on deploying the new beastie.frontfree.net (builder.frontfree.net at present). Because a bug(?) in FreeBSD kernel I have temporary disabled HTT on the box.
