Finally we were grant the permission of opening the technical forum again at frontfree.net, after several days of delay due to the election in Taiwan.

Someone (name not disclosed as this is potentially to generate trouble for him) has asked me to help upgrade his FreeBSD 4.3 deployment to a “workable” state.

Dong CHE has told me that mail from mail.freebsdchina.org has been bounced back because it was listed in rblplus.mail-abuse.org. From the query page I found mail.freebsdchina.org were listed in mail-abuse.org’s DUL by mistake (I believe so because the mail.freebsdchina.org block is not owned by dial up user).

With more and more aaazzz’s received on beastie.frontfree.net, it makes me to seriously consider the possiblity to set up a set of early filter on postfix.

From my statistics on beastie.frontfree.net, the winner is Worm.SomeFool family.

It’s really necessary to train a new security officer lead for Frontfree, if I must leave the campaus. While it will be reasonable if I will invest some of my time maintaing the server, they must deal some real-world problems theirselves, as I may be unable to reach these boxes in time.

As mentioned before, I will finally get the whole delphij.net out from beastie.frontfree.net because I will be finally graduated from the university and hence I must give maintainership (at least the principal maintainership) to someone who still live in the campaus so they can better solve problems encounted with. Well, I missed the post so much, as I have acted as principal maintainer and security officer there for more than three years: I became the security officer in 2000 when I joined the Association of Computer Machinery at School of Computer Science, Beijing University of Technology because nobody else in my grade can operate a Linux box :-)

As some of you may know, I am planning to buy a server with some friends and take it in an IDC by the time I will be graduated from the university. The server will be primarily do personal web, ftp hosting, as well as mail service and DNS service.

From Microsoft’s KB:

You can configure Microsoft Windows 2000, Microsoft Windows XP, and Microsoft Windows Server 2003 to write debugging information to three different file formats (also known as memory dump files) when your computer stops unexpectedly as a result of a Stop error (also known as a “blue screen”, system crash, or bug check). You can also configure Windows not to write debugging information to a memory dump file. Windows can generate any one of the following three memory dump file types:

1. Complete memory dump
2. Kernel memory dump
3. Small memory dump (64 KB)

Well, the story has end, beastie.frontfree.net ends its life because an overheat caused by mechanism fault of its fan on CPU and power supply. The hardware components were then replaced with some new ones.
