在右下脚加了一个的图标
还可以在context menu上加一个bloglines toolkit的菜单项
方便多了
要是能放到firefox sidebar上就更方便了

搞定iptables

家里的两台电脑，都是双系统。
XP自带的防火墙和NAT功能很不错
Linux的就要自己设了
惭愧的是一直也不会设
每次google出iptables的设置就头大了
今天正好刚装完FC3在yum update
另外一台笔记本上不了网
硬着头皮再google一次
好些文章照做了都不管用
终于翻了google几十页之后找到问题所在

把下文中加蓝部分放到我的/etc/sysconfig/iptables里才终于对了

修改/etc/sysconfig/iptables(把原有的内容都删除),修改完如下

# Firewall configuration written by lokkit
# Manual customization of this file is not recommended.
# Note: ifup-post will punch the current nameservers through the
# firewall; such entries will *not* be listed here.
*mangle
:PREROUTING ACCEPT [0:0]
:INPUT ACCEPT [0:0]
:FORWARD ACCEPT [0:0]
:OUTPUT ACCEPT [0:0]
:POSTROUTING ACCEPT [0:0]

*nat
:PREROUTING ACCEPT [0:0]
:POSTROUTING ACCEPT [0:0]
:OUTPUT ACCEPT [0:0]
[0:0]-A POSTROUTING -o ppp0 -j MASQUERADE
COMMIT

*filter
:INPUT ACCEPT [0:0]
:FORWARD ACCEPT [0:0]
:OUTPUT ACCEPT [0:0]
COMMIT

一周之内第三次装FC3

第一次装完了键盘鼠标都不对
第二次装发现了鼠标和我的WATCOM手写板冲突。
大概是因为没有重分区的缘故吧，把我原来的分区都在fstab
里写了一遍 usr1, home1, var1，最稀齐的居然还有一个　/1
哈哈
看着不爽，试图改fstab，结果之后就起不来了
嗯，其实我也不知道到底跟改fstab有没有关系，总之。。
只好重装
现在是在第三次的fedora core3下

抽取一个文件里的以CONFIG开头大写的词

这个代码是为了抽取一堆source code中的CONFIG_词
肯定还有很多情况不能很好处理

#!/bin/sh


grep "CONFIG_" $PATHOFPATCH/$PATCH | sed 's/[+#|\|\|\&|(|)|\$|=|:|\"|;]//g'| sed 's/,0//g' | sed 's/\/\*.*//g' | sed 's/[abcdefghijklmnopqrstuvwxyz-]//g'|sed 's/_\.//g' | sed 's/\.//g'|awk '{print $1"\n"$2"\n"$3"\n"$4"\n"}' | grep "CONFIG_"

35F2的perl版

#!/usr/bin/perl -w


 

while (<>) {

        while (m/(CONFIG_[A-Z|_|0-9]*)[\s|\)]/g) {

                print "$1\n";

        }

}

疑问：为什么sed删除所有小写字母不能用sed 's/[a-z]//g' ？
而必须用 sed 's/[abcdefghijklmnopqrstuvwxyz]//g' 这么难看的写法？

Fedora Core 3

终于装上了Fedora Core3
升级Core2
现在Alt+TAB不好使
不知如何解决涅

shell编程中expr的问题

LOOP=0
LOOP=`expr $LOOP+1`
这个时候LOOP结果是多少？

LOOP=0
LOOP=`expr $LOOP + 1`
这个时候LOOP结果是多少？

第一个结果是“0+1”
第二个结果是“1”

esmtp fetchmail mutt configuration files

俺们这有个VPN，这个可以理解，因为不能让任何人在任何地方
都能访问到公司内部的资源。
可是有个麻烦就是回家之后连公司的mail都收不到了
现在都globalization/internationalization了
经常要跟世界各地的人联系，
如果赶上周末，再加上时差的问题，会在礼拜一收到
很多的mail，加上公司的mail不一定都是公事等等其他原因，
迫切需要一个在家能收mail的方案。

俺鼓捣了个把小时，终于成功了。那就是用fetchmail收下来
再转到一个普通的帐户上去。当然了，熟的话几下子就设好了，
俺不是不熟么。。。。。。
这样单位机器不关就可以收下mail给家里发回去了

vsftp writable anonymous root问题的解决

500 OOPS: vsftpd: refusing to run with writable anonymous root
很多人问这个问题
google中文没人回答
google英文说的都含糊
其实只要把anon_root目录本身的 w权限去掉就可以了
比如 在配置文件中设定了 anon_root=/var/ftp
那么 /var/ftp就是这样：
dr-xr-xr-x 4 root root 4096 Nov 11 09:52 /var/ftp/
/var/ftp里就是这样：
drwxrwxrwx 3 ftp ftp 4096 Nov 11 11:15 incoming
dr-xr-xr-x 2 ftp ftp 4096 Jul 6 14:24 pub

mykill.sh

记得以前买过一本杂志
有一段代码是杀掉所有指定名字的进程
很感兴趣，因为像evolution这样的程序经常不会自己退出去
再起来之前必须手工杀掉，而且他有好几个进程，所以
必须一个一个手工杀掉
不过那本杂志忘了丢哪去了，只好自己琢磨着写了一个

#!/bin/sh
 
for you in `ps ax|grep $1|grep "^[ |0-9]"|grep -v "grep"|grep -v "$0"|awk '{print $1}'`
do

写了一个Hello World的gaim plugin版

折腾了好几天。

开始想写一个给gaim用的机器人，发现gaim.sf.net
上有个perl写的plugin例子。照着抄了一个发现基本不知他在不在跑。其实根本没跑。
因为：gaim安装时会给perl加Gaim module，否则use Gaim如何能生效呢？
可我的perl早就升到了5.8.5，目录位置早就不对了。找到一些用C写的例子，
不过代码太多了，嗯，我越来越发现自己岁数大了，什么也不原意深究了。
结果鼓捣perl鼓捣了两天。
Gaim的官方网站上根本没有用C写plugin的例子。
后来下载了一个SmartEar的plugin,才几十K，终于有兴趣往下看了......
一编译发现需要头文件，于是下载gaim-devel的rpm装。
还不对，
只好下载gaim的源代码，装了之后竟然启动就会segment fault，而root下就没问题。
想了想把自己用户目录下的 .gaim改个名。果然就启动好了。
其实，gaim.sf.net给的perl例子已经不能运行在最新的1.0.2下了。抓狂
偶尔在看版本信息的时候发现了gaim的irc在 freenode。
于是irc，/join #gaim。又问里面的人，终于有一个大概是gaim的开发者告诉了我
How to write a plugin for gaim by C language
还好，照葫芦画瓢搞出了第一个plugin。
