Security

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.

TERAMOTO Masahiro kindly gave maintainership of security/clamav to Rob Evers, the maintainer of the clamav-devel port.

Some search engines has grabbed some of my links out (Primarily, MP3). So I put some limits there. This is because I don’t want FreeBSDChina to be a MP3 downloading site - It’s harmful for the server, and we don’t want it.

The code is the following, it’s simple and effective:

This is the 6th security advisory of FreeBSD for the year 2004. The problem is with FreeBSD’s IPv6 implementation, which in turn does not affect our systems at all, because all servers I maintain has disabled IPv6 completely, since there’s no IPv6 devices available at Beijing University of Technology’s public network.

It’s believed that blog is going to be a victim of business spams, after mail spams :(

看来我不适合做特工，虽然这次是跟一群喜欢入侵的人打交道，但我的目的并不是进攻以两台服务器 :)

I’ve decided to disclose here (to a small group of people) due to the unresponsiveness from the phpBB group, which is the authoritive vendor of phpBB. A official public full disclose of this vulnerablity will be posted to BugTraq someday later.

Finally I have built it and deployed it. Apparantly, it DOES NOT WORK(detects spams correctly, but did not take any actions!), but I hope the virus filter will be working, as the viruses are growing too fast.

It appears that there are more and more limitations applied to forums because the election happening in Taiwan. Recently, one of my friend (Sarah Lau) has been deprived board management privilege at the NetEase Beijing Community because she has some saying which is considered to be harmful.
