Leopard InternetSharing Dhcpd Detected Another DHCP Server Exiting

If you active Internet Sharing in a large LAN (e.g. your company). You can share your internet to a subnet until your mac touch another DHCP server. The InternetSharing process will exit, even cannot open again.

Look at you system.log. You will find some word like below:
dhcpd: detected another DHCP server x.x.x.x, exiting.

There is a backend of Internet Sharing. You can find it at /usr/libexec/InternetSharing. It’s a binary executable file. When it running, it boot other server process: DHCP(bootpd), NAT(natd), DNS(named)

The issus is bootpd will exit when detected another DHCP server by default. Maybe you think change it’s config file. But wait. I have try that way. I make a file /etc/bootpd.plist and set detect_other_dhcp_server false. When I check InternetSharing, it rewrite my config file. And when I unchecked, it give my config file back. Amazed!

Ok. We must find another way. In bootpd man, there is an answer: If bootpd receives a SIGHUP (-1) signal, it will re-read its configuration and client binding files.

Let me try this:

  • create a file: /etc/bootpd.plist
  • open InternetSharing in sharing preferences panel
  • modify detect_other_dhcp_server to 0 in /etc/bootpd.plist
  • kill -HUP your_bootpd_pid

Look like it works. When bootpd process detected another DHCP server, it will talk about without shy.

Here is a ruby script: (usage: sudo ruby hup_bootpd.rb)

File.open("/etc/bootpd.plist", "r+") do |f|
  while l = f.gets
    if l =~ /detect_other_dhcp_server/
      puts "disable dhcp detect at line : #{f.lineno}"
      f.puts "\t<integer>0</integer>\n"
    end
  end
end

pid = `ps -e | grep bootpd | grep -v grep | awk '{print $1}'`

puts "tell bootpd reload configure : #{Process.kill('HUP', pid.to_i)}}"

从 Safari4 退回 Safari3

当你决定输入这个关键词进行搜索的时候, 我猜你和我碰到了同一个的麻烦.
When you type this keywords in google. I guess you are in trouble like me.

新版本有时候会占用大量的CPU, 导致温度升高, 风扇变快, 最高记录是: 70度 6000转.
The new version make high cpu time, high temp and fast fan. The top record is: 160F 6000rpm.

Safari 无法从高版本直接降回低版本, 也没有提供卸载工具.
You cannot install the old safari directly, and there is not uninstall tool.

系统是如何判断版本的? 答案是:
How the os detect my version? The answer is:

/System/Library/Frameworks/WebKit.framework/Resources/Info.plist

把文件中的 “5530” 改成 “5525”, 也就是 Safari 3.2.3
Replace “5530” to “5525” in that file.

同时, 你还需要将 Safari.app 从应该程序里移走. 还有 ~/Library/Safari/ 下面的偏好设置, 否则 Safari 无法启动.
You need move away Safari.app from /Application to other folder. Also old preferens ~/Library/Safari/. Safari cannot run with them.

好了, 现在你可以安装 Safari 3.2.3 了.
OK~ You can install safari 3.2.3 now.

重启后, 首先启动一次 Safari, 然后将偏好设置放回去. 那个 TopSites.plist 应该没什么用.
After rebot. Open safari first then close it, move back you preferens file. Maybe you can drop TopSites.plist.

IE Png 透明

ie png opacity

记得许多对IE不满的设计人士都会提到IE不支持PNG透明这个问题, 我不是个WEB开发者, 不过也曾经碰到过一次, 着实是郁闷了一回.

今天闲来无事想去下载一个flv文件未果, 没搞清楚那个站是怎么做到的, 竟然会在IE缓存目录里不留痕迹.

虽然没下到视频, 不过乱翻却有所收获, 一种让IE支持透明PNG的方法: http://www.twinhelix.com/css/iepngfix/

照着网站的说明做, 很简单, 在样式中加入一个htc文件:
