Linux下通过USB用WM6手机的GPRS上网

Jay Xie — Sun, 18 Jan 2009 14:59:45 +0000

From http://wiki.xda-developers.com/index.php?pagename=Hermes_Modem_With_Linux

但并不是一定得用Hermes这个机器，我用的是Dopod D600，所谓的GENE，按照文中所述编译安装了usb-rndis-lite后，在手机上用Internet共享拨号连接后，NetworkManager就找到了一个新的网络设备，这时候就连接成功了

a google chrome like color schema for sawfish using mxflat theme

Jay Xie — Tue, 06 Jan 2009 02:39:46 +0000

mxflat theme can be found in sawfish-themes package in both ubuntu and debian.

I made a google chrome like color schema using this theme with settings below.

This is the sample image, the browser is swiftfox with chromifox theme.

Also you can make a shadow~

Here is the auto-generated configuration with sawfish-ui.

(custom-set-typed-variable (quote mxflat:fake-shadow) (quote ()) (quote boolean))

用adsl时如何使用dnsmasq

Jay Xie — Sun, 05 Oct 2008 12:29:06 +0000

前面写过一篇帖子，是关于用dnsmasq做dns缓存的，里面提到的dsl部分采用的是注释掉usepeerdns，这并不是很好用，因为无法获取运营商的dns server
简单的做法是在/etc/ppp/ip-up.d/0000usepeerdns里cat /etc/ppp/resolv.conf前加上一句echo “nameserver 127.0.0.1″ 把那一段变成这样即可。

# merge the new nameservers with the other options from the old configuration
{
  echo "nameserver 127.0.0.1"
  cat /etc/ppp/resolv.conf
  grep --invert-match '^nameserver[[:space:]]' "$REALRESOLVCONF" || true
} > "$REALRESOLVCONF.tmp"

msn-pecan pidgin的msn插件期待离线消息功能

Jay Xie — Mon, 19 May 2008 08:39:31 +0000

http://code.google.com/p/msn-pecan/

作者是pidgin的msnp主要开发者，说是pidgin忽视msnp的开发，所以独立出来作为一个插件。
目前已经支持了personal-message 离线消息放在了milestone-0.1.0 目前版本为0.0.12

try it!

swiftfox, 让你的firefox不再慢如牛

Jay Xie — Wed, 05 Sep 2007 02:24:14 +0000

其实牛挺好的呵呵

昨天和委员交流linux使用心得，一致对linux下firefox那个慢是深恶痛绝，回来以后就开始找找看有没有解决办法，因为我们一致认为，linux最大的好处就是没有解决不了的问题。

于是，就找到了swiftfox

http://getswiftfox.com 是官方站目前是2.0.0.6和2.0.0.7pre 可以上去下载

debian系的可以这样做在sources.list里添加一条
deb http://getswiftfox.com/builds/debian unstable non-free
然后根据你的cpu类型安装swiftfox-xxx 比如我是pentium-m我就装swiftfox-pentium-m

唯一遗憾就是没有源码不知道是怎么样优化的

优化后的最直接的效果就是访问msn space不再是100%cpu卡上数秒了~~

GNU screen

Jay Xie — Tue, 10 Jul 2007 01:54:25 +0000

一直以来都是term term term，N个term，刚看到screen的时候觉得多此一举，反正已经是term*N很容易的，都配成sawfish的快捷键了……
这儿有个how to start screen from .bashrc不过偶不喜欢，因为这样只能启动一个terminal，每次都会接管上一个screen。
于是配成了另一个sawfish的快捷键，目前我的快捷键如下：
Win+e 启动emacs或跳转到已启动的emacs
Win+t 启动thunderbird或跳转到已启动的thunderbird
Win+m 启动mlterm
Win+z 启动一个mlterm，在里头执行screen
Win+p 启动python解释器
Win+x 启动rox
Print 抓屏
Alt+Print 抓窗口

配置文件里这样写：

(when (require-try 'jump-or-exec)
  (bind-keys global-keymap
             ;; emacs
             "H-e" `(jump-or-exec "^.*Emacs@JayXie$"
                                  ,(lambda () (wy-run "emacs &")))
             ;; thunderbird
             "H-t" `(jump-or-exec "^.*Thunderbird$"
                                  ,(lambda ()(wy-run "mozilla-thunderbird &")))
             "H-m" `(wy-run "mlterm &")
             "H-z" `(wy-run "mlterm -e screen -dR &")
             "H-p" `(wy-run "mlterm -e python &")
             "H-x" `(wy-run "rox &")
             ;; capture screen
             "Print" '(wy-run "shotfile=~/Screenshot_`date +%F_%T`.png;scrot $shotfile && display $shotfile")
             ;; "H-c" '(wy-run "shotfile=~/Region_`date +%F_%T`.png;scrot -s $shotfile && display $shotfile")
             "M-Print" 'capture-this-window
             ))

Ubuntu Gutsy

Jay Xie — Fri, 06 Jul 2007 04:50:18 +0000

呃，升级了之后一直报错，device-manager dm-linear device lookup error.
据说是内核需要patch，ubuntu的bug list里有，所以等等吧，幸亏2.6.20的内核还在，用这个启动就行了，hoho
顺便要说的是，之前的dual head双显不行了，在recovery模式下X -configure重写了下xorg.conf，当然，最好是dpkg-reconfigure xserver-xorg
双显啊双显，啥时候才能用的很爽呢……

好吧，接着写，关于i810的dual head

Jay Xie — Thu, 21 Jun 2007 03:58:00 +0000

之前写过，但是用的很不方便，在/etc/X11/下放了两个xorg.conf 分别对应dual head和single head用脚本来切换
但是太麻烦了得重启xwindow
于是把xinerama关了
但是问题就是sawfish只跑在主显示器上了
没法子写了个脚本
DISPLAY=:0.1 sawfish &
这样就不用每次都切换xorg.conf了

不过再一个麻烦事又来了……
窗口不能随便拖了～～～～

遭遇thunderbird丢失邮件

Jay Xie — Thu, 07 Jun 2007 08:16:40 +0000

恩，写下来给其他人参考，如果也不幸遇到了的话，呵呵
找到你的邮件，比如Inbox 重命名为Inbox2
然后执行

sed '/^X-Mozilla-Status:/s/[0-9]*$/0000/' <Inbox2 >Inbox

重置了邮件的状态，所以最后一次compact this folder后删除的邮件也回来了……

vmware under feisty

Jay Xie — Sun, 25 Mar 2007 03:39:50 +0000

vmware-workstation的内核模块在2.6.20下编译不过，可能有解决方案，不过网上有现成的更好的办法，就是改用vmware-server

到vmware下载vmware-server，解压开来装上，问你是否执行vmware-config.pl的时候选no

然后开始cheat。

先 apt-get install vmware-server-kernel-modules

这个是ubuntu源里面别人编译好的vmware-server的内核模块，能够保持和内核的一致
然后sed -i -e "s/\/sbin\/insmod -s -f \"\/lib\/modules\/\`uname -r\`\/misc\/\$1.o\"/\/sbin\/insmod -s -f \"\/lib\/modules\/\`uname -r\`\/vmware-server\/\$1.ko\"/" /etc/init.d/vmware

这里和原文不一样，改的是vmware启动脚本里面关于加载内核模块的地方，原文是改成了modprobe一下，但是我不知道啥时候insmod，所以我就改成了这个，源里面针对2.6.20编译的内核是以ko结尾，而且是放在vmware-server下

再然后sed -i -e "s/sub configure_module {/sub configure_module {\n return 'yes';/" /usr/bin/vmware-config.pl

这个是hack掉vmware-config.pl里面安装内核模块部分，vmware-server自带是没有2.6.20的，自己编译可能还有什么问题，所以用别人编译好的，这里直接return yes;最好

之后就全ok了，跑一下vmware-config.pl吧

注：以上步骤都需要root权限

开始学写shell

Jay Xie — Sat, 27 Jan 2007 08:27:35 +0000

磕磕碰碰的写完了一个预处理的脚本，很简单，用来对代码里面的#ifdef DEBUG … #else … #endif来做处理如果脚本没带参数就认为启用DEBUG 带参数就认为不启用DEBUG 弱的很暴汗……

其实以前也写过shell脚本，简单的比如切换有线和无线，复杂的比如解决rar x的中文问题（不过新版本的rar貌似没这个问题了），但还是好多东东要学@.@ 还得在实践中一点一点的被lisp给侵蚀着呵呵

ubuntu下用vpnc连入cisco vpn

Jay Xie — Sat, 06 Jan 2007 02:29:05 +0000

之前转载过一个cisco的vpnclient的帖子，是要自己编译安装的，所以一直没空尝试

昨天还是前天来着突然想到ubuntu源里面应该已经有现成的vpnclient了吧，找了找果然有个vpnc。
于是刚刚看着vpnc的long-help试了试就搞定了

首先需要的是windows下有个配好的cisco vpn client，或者你有group的密码
windows下vpn client下profiles里面是相应的配置文件
/etc/vpnc.conf文件里面照着现有相应的pcf文件写就行了

IPSec gateway [ Host in .pcf ]
IPSec ID [ GroupName in .pcf ]
IPSec obfuscated secret [ enc_GroupPwd in .pcf ]
Xauth username [ your user name ]

如果直接有group密码那么把IPSec obfuscated secret换成IPSec secret然后写上你的密码或者直接sudo vpnc-connect然后输入ip,group name,group pwd,user name,user pwd连接也就ok了
