项目马上要PK了,急啊!

2010-7-28 Ray Work notes

最近比较折腾,huawei的项目马上要PK了,性能还未达标,公司内部已将其列为紧急状态,天天要更新数据报告。

这个项目是多频段GSM850/900/1800/1900+WCDMA850/900/1900/2100,主要难点在于阻抗适配,GSM1800频段对阻抗极为敏感,在容性区时TRP均能达标,放在感性区功率立马就降下来了。这还不是最令人郁闷的,更变态的不是提高功率而是如何降低TRP。功率高的话当然好,随之而来的是SAR测试超标,EU和US的标准不同,US标准更为严格,所以必须通过降低TRP把SAR降下来。

GSM900在容性区性能较好,但是调整低频会出现TRP达标而TIS最后信道不够的情况,目前尚未找到解决办法,眼看着PK日期一天天临近,实在是折磨啊 。

下午来了个Hengxin的项目,GSM900/1800+TD-SCDMA,客户急着赶时间给移动入库,所以明天必须将天线图纸发去深圳工厂线割,否则就误了客户的样品交期。时间紧迫,赶紧做无源治具调试,发现高频带宽窄,做1800单频还勉强合适。看下圆图,高频的mark点集中在第四象限,可以通过匹配电路调整。

匹配电路是两并两串,双L型,尝试在ANT端串电感,发现圆图位置基本上没变化。把靠近ANT端的匹配位置改为0欧直通,靠近PA端串4.7nH,对地的并位空置,看下S11图,高频带宽已经OK了,看下S21增益,辐射好强,哈哈搞定。

晚上安排测试SAR和无源,Hengxin项目明天应该可以发去线割了,呵呵

路由器安装squid实现透明代理

2010-7-20 Ray Router

在vortex86上安装squid并设置为代理服务器,用起来感觉打开网页的速度有很大提升,突发奇想打算把squid装到路由器上做成透明代理,缓存代理80端口的访问。

belkin路由器,刷了Tomato Pandora 并设置好了optware环境,看了下optware的package里面包含了squid,直接ipkg就是了。

Tomato v1.27.0470 -R1 K26 USB Std

Enter 'help' for a list of built-in commands.

You should review the configuration file /opt/etc/squid/squid.conf,
make any necessary change, and complete the install by running -
/opt/etc/init.d/S80squid start

Successfully terminated.

安装完毕,直接/opt/etc/init.d/S80squid start,进程马上就挂掉了,估计是配置文件没搞好,研究下吧。

看下log文件里面的启动记录:

2010/07/20 18:31:43| Starting Squid Cache version 2.6.STABLE23 for mipsel-unknown-linux-gnu...

哦,原来是没有初始化磁盘缓存文件夹,偶来初始化一下,然后在配置文件里指定下缓冲存取用户和组:

cache_effective_group nobody

初始化之后可以正常启动了,定义下服务器的地址和端口,transparent表示支持透明代理:http_port 192.168.2.1:8080 transparent

 设置下缓冲所使用的内存和磁盘缓存目录:
cache_mem 8 MB
cache_dir ufs /opt/var/squid/cache 40 16 256

定义防火墙规则:
http_access allow all

然后设置iptables防火墙规则:
iptables -t nat -A PREROUTING -i br0 -p tcp -s 192.168.2.0/24 --dport 80 -j REDIRECT --to-ports 8080

解释一下,ifconfig看下,由于之前在conf文件里定义了代理服务器的端口和地址,192.168.2.1:8080,,所以要把目标端口为80的访问重定向到192.168.2.1:8080,看了下192.168.2.1的网络接口是br0,所以itables规则应该写成上面的形式。

 /opt/etc/init.d/S80squid reload一下,发现已经生效了。

使用效果如何,待我后续慢慢感受下,嘿嘿

cache_effective_group nobody
visible_hostname Tomato-Pandora
cache_mgr webmaster
cache_mem 15 MB
#cache_dir /opt/var/squid/cache null
cache_dir ufs /opt/var/squid/cache 40 16 256

squid技巧整理

2010-7-19 Ray Linux

在Vortex86上面装了squid,做缓存代理服务器,试验下效果不错,顺便把一些技巧整理记下来,以后用的时候就不用放狗到处狂搜了!

1.squid 错误页面显示中文:
vi squid.conf
把# error_directory /usr/share/squid/errors/English
替换成下面内容
error_directory /usr/share/squid/errors/Simplify_Chinese

2.squid缓存错误页面的处理
Squid 默认将错误页面也缓存起来, 如果你先开启了一个不存在页面,然后你上传了页面, 由于被cahce住默认5分钟内都得到的是错误的页面,在squid中增加下面一行可以解决这个问题
negative_ttl 0 second  意思不缓存"连接失败"和"404 not Found"的页面.

优化Vortex86系统下的Debian5启动环境

2010-7-18 Ray Linux

Vortex86小主机性能比较弱,和台式机的CPU动辄双核四核CPU没法比,有必要精简下系统,去除不必要的组件。最大程度的压榨系统的性能是DIYer们孜孜不倦追求的境界。

看了一下,开机启动的服务有以下几个:

  • acpid
  • atd
  • cron
  • exim4
  • linux_logo
  • nfs-common
  • openbsd-inetd
  • rmnologin
  • rsyslog
  • samba
  • smartmontools
  • ssh
  • stop-bootlogd
  • webmin

1.先停掉exim4,然后禁止它开机自动启动。Exim4是Debian默认的邮件传输代理(MTA),下载机兼NAS不需要mail服务,这个东东完全可以去除。

2.已经设定了ssh登陆的logo界面,可以删除linuxlogo程序了。

3.我已经安装了samba,nfs-common就不需要了,禁止它开机启动。

4.关闭不需要的tty,编辑/etc/inittab,找到如下一段:
1:2345:respawn:/sbin/mingetty tty1
2:2345:respawn:/sbin/mingetty tty2
3:2345:respawn:/sbin/mingetty tty3
4:2345:respawn:/sbin/mingetty tty4
5:2345:respawn:/sbin/mingetty tty5
6:2345:respawn:/sbin/mingetty tty6

注释掉后面的四个,执行 init q 这个命令即可。q作为参数的含义:重新执行/etc/inittab中的命令

5.停掉并禁止开机启动rsyslog服务,性能为先,监控并记录日志就免了吧,有问题的话再开了看下。

暂时先这么搞,以后有想起来的再慢慢优化。

vortex86,Debian环境下编译安装mldonkey

2010-7-18 Ray Linux

安装了debian,发现源里面的mldoney是2.9版本的,有前车之鉴,知道这个版本修改download.ini文件后最容易出现无法启动的问题,直接安装新版3.0.1吧。

下载了mldonkey3.0.1的deb文件,dpkg安装下发现有一大堆的依赖关系,悲剧,还是本地编译吧。

先安装编译环境 apt-get install build-essential ,然后./configure一下发现还有包没安装。提示:   

  Checking system libraries.
-----------------------------------
----- checking zlib (required)

Zlib missing, did you install zlib and zlib-developer packages?
需要安装zlib和它的开发包,搜了一下,发现apt-get install zlib1g-dev即可解决。安装后再试一下,已经解决了!

To produce a release tarball execute: make release.mlnet.static
To clean the build directory execute: make maintainerclean

Compiling CryptoPP.cc can take several minutes, on slow machines up to half an hour.
 

OK,开始编译,CPU占用超高啊!

啊哈,编译中又报错,忘了截图了,看出错提示貌似是跟ocaml有关,想了一下,类似问题之前遇到过,删除了mldonkey-3.0.1文件夹,重新解压mldonkey.tar文件,再configure,然后make就不会报错了。

用U盘给vortex86安装Debian

2010-7-18 Ray Linux

整了个vortex86的小玩具,配置为sis550单芯片/Pentium MMX 166/128MB SD内存(显卡动态分配8~32M)/SiS 550显卡/SiS 7019声卡/Realtek 8100网卡/3*USB1.1/1*LPT,采用5V3A的外接直流电源供电,尺寸13.6×11.8×6cm,刷了最新的BIOS之后主频为200Mhz。虽然性能差了点,但体积小又是X86架构,可以选择的系统也多,到手后找了个SATA2.5寸硬盘用转接卡转接为IDE44pin接上去,开始安装系统。

点击查看原图

点击查看原图

开机进BOIS发现可以支持USB-CDROM启动,把U盘量化为CDROM,插上去可以识别为USB光驱,但是启动失败,换了不同的ISO文件都是如此,看来这个方法行不通,必须得找USB光驱安装了。

放狗搜了一下,发现这个主机还可以从HDD模式启动,一不做二不休,把U盘量化为HDD模式,用ultraISO将iso镜像文件以hdd+模式写入,开机按F8选择hdd模式的U盘,顺利进入安装界面!

点击查看原图

可以接下来系统要检测CD-ROM设备,检测不到CD-ROM设备就自动拒绝往下安装了,悲剧啊!

正好手里还有个U盘,想了个办法,把另一个U盘加载同样的ISO文件量化为USB光驱的模式,瞒天过海希望能骗过固执的linux。

试验下,果然成功了!

Tomato固件下用iptables实现端口白名单功能

2010-7-15 Ray Router

公司目前用的是TP-LINK家用无线路由,使用人数一多就频繁出现死机症状,每次都要去机房重启路由器,不胜其烦。

研究了一下传说中的企业级路由器,发现无外乎是IXP42X处理器加linux核心的固件,售价都在六七百元以上,功能多一些的路由器要价1K以上,本着为公司节约成本的考虑,偶打算用belkin路由器加第三方固件来实现比企业级路由器更为强悍更加灵活的功能。

基于linux的第三方开源固件大致有openwrt,ddwrt,tomato三大分支,openwrt功能过于强大过于专业,管理配置多有不便;ddwrt适合DIY玩家,tomato适合网吧及小型ISP用户,偶就选择tomato吧。

刷了Tomato Pandora 固件,ssh看下,发现内核已经更新为2.6.22了。由于要实现内网用户只能收发邮件,所以只能开放wan口的tcp53,25,110以及udp53端口。tomato的功能有限,通过路由器的web界面无法设置,只好ssh进去用iptables来做。

想到iptables里面INPUT定义为所有收到的并且目的地址为本机的报文都会经过这个链,而不管哪个接口进来的或者它往哪里去,就写了个规则出来:

iptables -I INPUT -j DROP
iptables -I INPUT -p tcp --dport 25 -j ACCEPT
iptables -I INPUT -p tcp --dport 110 -j ACCEPT
iptables -I INPUT -p tcp --dport 53 -j ACCEPT
iptables -I INPUT -p udp --dport 53 -j ACCEPT

试验一下居然把端口全都封杀了,甚至无法解析IP。

想了一下转发过滤不能在INPUT链上做,改在FORWARD上面来试试:

iptables -I FORWARD -j DROP
iptables -I FORWARD -p tcp --dport 25 -j ACCEPT
iptables -I FORWARD -p tcp --dport 110 -j ACCEPT
iptables -I FORWARD -p tcp --dport 53 -j ACCEPT
iptables -I FORWARD -p udp --dport 53 -j ACCEPT

还是不行,结果一样,所以端口全被封杀了。

得到论坛朋友指点,原来忘记了通信是双向的,应该用-o参数指定界面。嗯,指定wan口来写规则就可以达到目的。

看下路由器的网络接口:

发现wan口对应的是vlan1,于是防火墙脚本应该这样写:

iptables -I FORWARD -o vlan1 -j DROP
iptables -I FORWARD -p udp --dport 53 -j ACCEPT
iptables -I FORWARD -p tcp --dport 53 -j ACCEPT
iptables -I FORWARD -p tcp --dport 25 -j ACCEPT
iptables -I FORWARD -p tcp --dport 110 -j ACCEPT

试验一下,成功!

Tomato Pandora firmware for Belkin 7231-4P

2010-7-10 Ray Router

无意中发现Tomato Pandora已经支持belkin 7231-4P了,立马下载来试用一下尝尝鲜

看了一下,有3G版和VPN版两种,VPN版本不支持USB设备,并且精简了ssh,于是改刷3G版本,虽然偶不需要使用3G USB网卡,哈哈。

刷完看下界面,果然增加了许多东西,不错不错,不过偶最关注的还是USB和NAS。

点击查看原图

迫不及待插上U盘试下,很顺利地识别并挂载了!

点击查看原图

OK,偶来给路由器安装ipkg环境:

  1. 把U盘mount到jffs:mount /dev/sda1 /jffs
  2. 建立opt文件夹:mkdir /jffs/opt
  3. 将/jffs/opt挂载到/opt:mount -o bind /jffs/opt /opt
  4. 然后运行mkswap将刚刚建立的swapfile文件设置成swap文件:mkswap /jffs/Swapfile

然后就悲剧了,提示没有这个指令,估计作者把mkswap给精简掉了,偶先装optware环境吧。

比较懒,找了个自动安装脚本(http://pandoric.googlecode.com/svn/Pandora%20%e8%84%b1%e6%9c%ba%e8%bd%af%e4%bb%b6/optware-install.sh ),一键安装多快好省,哈哈

开始运行这个脚本:root@Belkin 7231-4P:/jffs# ./optware-install.sh
Checking system config ...
Using 192.168.1.1 as default gateway.
Using the following nameserver(s):
nameserver 210.22.70.225
nameserver 210.22.70.3
Warning: local nameserver is different than gateway!
Check config or enter:
  sed -i s/192.168.*/192.168.1.1/ /tmp/resolv.conf
to correct this.

啊哈,居然提示我网关和DNS server的地址不一样!DNS难道非得和网关一样才能解析么?这叫什么逻辑哟!
打开这个脚本看下,删除了检测DNS的步骤,继续安装,成功!

嗯,很好很强大,这个脚本直接设置好了环境变量,直接ipkg安装就可以啦!安装busybox以便等下使用mkswap工具初始化swap

嗯,成功初始化swap并挂载它。

顺便把这些开机需要执行的指令丢到启动脚本里面去。

 重启路由器,发现并没有自动挂载,大惑,dmesg看了下启动过程,发现系统启动到初始化USB storage设备大概需要6秒左右的时间,好吧,那就让它先sleep 10 ,这样应该就可以啦。

嗯,重启路由器之后自动按照脚本挂载USB设备到jffs并成功加载swap!

贴一下偶的开机脚本和修改后的一键安装包。

sleep 10
mount /dev/sda1 /jffs
mount -o bind /jffs/opt /opt
sleep 3
swapon /jffs/Swapfile

ipkg环境的一键安装包:optware-install.rar

一时冲动,买了龙芯板子

2010-7-7 Ray DIY and Geek

一时冲动,在论坛里看见龙芯架构的路由板子开卖的消息,就拍下一块。

点击查看原图 点击查看原图

以下是卖家提供的信息:.
128M SDRAM, e-sata一个 sata板载一个(提供SATA电源支持), 16M NOR flash (TE28F128) , 4个10/100网口(IC PLUS),支持VLAN划分。 1个usb 1.1接口 。. 1个SD卡槽. cq8401 mips base 400Mhz 龙芯cpu , 1个mini-pci槽.一个reset按键。 TTL 排针的serial pin

软件提供
1:UBOOT源代码。
2:交叉编译环境
3:linux (openwrt 8.09 ported)
4:所有板上硬件的linux driver. 应用程序自己编译了(mipsel base)

拍下之后卖家告知SD读卡器是GPIO控制的,没有开发相关驱动,无法使用。USB又是1.1的,传输速度一定抓狂,手里没有SATA的硬盘,为此去买一个硬盘似乎很没必要,看了一下卖家发来的开发包,找不到config文件,郁闷。

在网上查了一下,debian官方没有提供针对龙芯的版本,民间倒是有人做出了debian包,估计解压到u盘然后chroot应该可以跑了,不知道需不需要打patch。还是算了吧,折腾点大众的东东比较合适,遇到问题也方便解决。

今天终于到货了,跟卖家协商一下,偶付了来回邮费把板子退回去了,以后买东西要查清楚再下手,再也不能被所谓的爱国芯之类的言论忽悠了。
