SysAdmin

The service there is expected to be down for a while. I think I can get everything back tomorrow.

半年了，我再也忍不住了，今天我一定要骂人。

从春节到现在，几个月？春节、五一，是不是这些厂商还想看着我们这样过到十一、新年，乃至下一个春节？

凌晨三点半被同事的电话叫醒，说是……

Colin has finally added portsnap and related stuff (bsdiff, etc) to FreeBSD 7.0-CURRENT. This would not be MFC’ed before 6.0-RELEASE, but still good enough because it will attract more users to use it.

Portsnap is a secure and efficient alternative to the current ports tree update approach. Since it goes through HTTP, it is much easier than other existing methods to use it to obtain ports, especially from some brain-damaged administrated networks.

This is an important step of getting the tools like freebsd-update and portsnap into base system, which provides good method of updating the base system (through binary updates) and ports tree.

So finally they have released it, maybe I will use it at company, but not on my boxes since they run php 5.x series, hahaha…

Seems that my server keep tuning its clock, somewhat weird…

没完没了的phpBB漏洞！！再也不能忍下去了！

今天终于找到alu跟他要了www的root，然后开始升级。

首先import新版本。

然后开始合并冲突，phpBB这群家伙居然到了这么多的patchlevel还在改表结构，真不知道他们的大脑是用来想什么的，预想www必然会出问题，果然，不过一切在掌控之中。

We are only 1 day to the great 6.0-STABLE code freeze, which will result in 7.0-CURRENT, 6.0-STABLE, and finally, 6.0-RELEASE!

Deploy FreeBSD on your spare boxes, g/f’s laptops, etc., to help us toward an excellent release!

Sometimes, when you are in a NAT’ed environment, ssh connection may be dropped when the gateway is busy.

OpenSSH has provided a solution against this.

The option is called “ClientAliveInterval”. With this setting in your sshd_config, sshd(8) would send a ping message through the encrypted channel periodically, thus prevent the early drop.

The default setting is 15, meaning the ping period is 15 seconds.
