为了在我的 Dopod S1 上使用 Microsoft Office Communicator Mobile ,去微软网站下载了客户端程序:

http://www.microsoft.com/downloads/details.aspx?FamilyID=2EEA3E24-F216-4887-92B0-F37D942E26E0&displaylang=zh-cn

版本是 2.0.468.1 发布时间是 2008/12/28

安装到手机后,在手机里导入CA服务器证书链(*.p7b),并设置好内外部服务器参数,登录时出现:

在可以登录之前,必须更新 Communicator Mobile 的版本。请联系管理员获取正确的版本。

根据微软论坛上的提示,必须修改客户端版本过滤策略:

OCS 前端服务器上:

在边缘服务器上也要进行类似的操作

利用周六空闲的时间,将两个不同域(不同地理位置)的OCS 2007进行了对接(联盟),可以互相添加对方域的SIP帐号,实现文字对话(语音还未测试)。

前期准备:
公司内部已经安装了一台前端服务器,域内用户可以正常使用文字沟通;
X3220+4G+2*250GSATARAID1+S3000AH 作为 边缘(Edge)服务器硬件;
Windows 2003 Enterprise Server R2 x64;
cn_office_communications_server_2007_enterprise_x86_cd_X13-79083.iso;

操作系统安装完后,打上全部的操作系统漏洞补丁,放入OCS2007安装光盘,部署边缘服务器角色。

根据网络上的若干文档,配置好边缘服务器。验证方法:
在外网,使用OCS Client工具,填入边缘服务器的外部接口的FQDN,能正常登陆,且和内部用户能正常沟通。

注意点:因为边缘服务器不允许加入域,所以OCS Client在外网登陆时,不能使用 Domain\Username 方式,必须改成 Username@SIPDomain.com 方式登陆

接下来,就要双方的OCS管理员进行配合了:
登陆各自的前端服务器(池),设置全局属性,选中 “启用联盟和公共IM连接”

xmedge.xxxxx.com 是边缘服务器外网IP对应的FQDN。

接下来到边缘服务器中,运行 compmgmt.msc -32 ,在服务和应用程序中,找到 OCS 2007 ,右键属性

在允许联盟伙伴列表中,将对方的SIP Domain以及Edge FQDN填进去

打开证书向导,导入对方的CA证书链(双方通过访问 http://xxxxx/certsrv 下载各自的CA证书链*.p7b,然后互发给对方)

最后,还要注意,要在各自的外部DNS服务器上创建两条 SRV 解析记录:

_sipfederationtls._tcp.xxxxx.com. 3600 IN SRV 0 0 5061 xmedge.xxxxx.com.
_sip._tls.xxxxx.com. 3600 IN SRV 0 0 443 xmedge.xxxxx.com.

在调试联盟过程中,有几个辅助工具可以利用一下:

一种就是边缘服务器管理工具右侧工具栏中的 验证向导

还有就是
Microsoft Office Communications Server 2007 Best Practices Analyzer
http://www.microsoft.com/downloads/details.aspx?FamilyId=1B90993C-072A-4C84-B385-B76D23B2F27C&displaylang=en
http://download.microsoft.com/download/3/f/f/3ff86a15-64cf-4fd3-94af-ebfeea59c3aa/RTCBPA.msi
is a diagnostic tool that gathers configuration information from a Microsoft Office Communications Server 2007 environment and determines whether the configuration is set according to Microsoft best practices
需要
.NET Framework 2.0
Office Communications Server 2007 Administrative Tools (OCS安装光盘中有这个管理工具)

红帽子在09年1月20日发布了 Red Hat Enterprise Linux 5.3 (rhel5.3/rhel5u3)

Release Notes: http://www.redhat.com/docs/en-US/Red_Hat_Enterprise_Linux/5/html/Release_Notes/index.html

有想尝鲜的朋友可以试一下 Google “rhel-server-5.3-i386-dvd.iso” 应该可以找到下载点,我找到一个,平均下载速度可以达到400~500KB/s,2个小时左右就OK了。

rhel-server-5.3-i386-dvd.iso 大小 3013859328 Byte

下完了比对一下MD5值:371c62851611fd32ead440df6f24a296

在 Linux 下挂载成loop设备,找到 images/boot.iso 刻录成CDROM,然后再用NFS网络安装,可以省不少事。

驱动更新信息:

    the SCSI device handler infrastructure (scsi_dh) has been updated, providing added support for LSI RDAC SCSI based storage devices.
      the tg3 driver for Broadcom Tigon3 ethernet devices has been updated to version 3.93. This applies several upstream changes for new hardware. However, the 5785 hardware is not fully supported. This device may be detected by the driver, but lack of PHY support may cause these chips to not function correctly and may require the user disable any on-board 5785 cards in the system BIOS.
        scsi-target-utils now features iSCSI Extensions for RDMA (iSER), which is based on the Linux Target (tgt) framework. iSER is included in this release as a Technology Preview, and provides capabilities for both single and multiple portals on different subnets. Note, however, that there are known bugs with using multiple portals on the same subnet.
        To set up an iSER target component, install the scsi-target-utils and libibverbs-devel packages. The corresponding library package for your system’s Infiniband hardware is also required. For example, in HCAs that use the cxgb3 driver the libcxgb3 package is needed, and for HCAs using the mthca driver the libmthca package is need.
          The MPT Fusion driver has been updated to version 3.04.06, providing the following bugfixes and enhancements.

多普达S1行货(移动心机) 在系统初始化后,会安装一些中国移动的定制软件。占用了不少机身存储空间。我在运行GPS导航软件时,有时会感觉到系统反应迟缓。

网络上有介绍一些优化的办法。我的优化步骤:

开始 -> 设置 -> 系统 -> 内存 ,可以看到内存的大小以及使用情况:

存储(FlashROM)总容量:30.44MB,剩余:12.50MB
程序(RAM)总容量:47.90MB,剩余:18.20MB

[Dopod S1 普通版的ROM为128MB,RAM为64MB;精英版的ROM为256MB,RAM为128MB] 很明显我的是普通版的 囧

存储内存的优化,可以通过删除/移动预装软件来达到减少空间占用率。
\Program Files\* (如 Mobile Stock;PowerWord;PushEmail)

程序内存的优化,可以通过减少自动运行的后台程序来实现减少空间占用率。
\Windows\StartUp\*.lnk (如 MobileAnimationTimer.lnk)

内存优化工具:DinarSoft MemMaid 和 Pocket Mechanic
手机管理工具:掌智手机助手 (直接在电脑上管理手机,很方便)

搞完以后,ROM剩余19.21MB,RAM剩余19.01MB。感觉RAM还可以进一步优化一下。

目前的进程列表:
\Windows\APLauncher.exe (TouchFLO相关)
\Windows\Biotouch.exe (TouchFLO相关)
\Windows\connmgr.exe (连接管理器)
\Windows\cprog.exe (与拨号功能相关)
\Windows\device.exe (硬件设备管理)
\Windows\filesys.exe (文件系统管理)
\Windows\gwes.exe (GUI Windows Event System)
\Windows\MediaHubMini.exe (TouchFLO相关)
\Windows\nk.exe (内核接口程序 kernel)
\Windows\poutlook.exe (pocket outlook,PIM管理 日程 联系人)
\Windows\QuickDial.exe (拼音字母找联系人功能)
\Windows\rapiclnt.exe (USB连接管理)
\Windows\repllog.exe (ActiveSync手机端)
\Windows\rnaapp.exe
\Windows\services.exe (系统服务管理)
\Windows\sddaemon.exe (speed voice dial 又或者是microsd卡相关? 可关)
\Windows\shell32.exe (动态链接库)
\Windows\tmail.exe (短信/Email 相关)
\Windows\udp2tcp.exe (ActiveSync相关)

如果将TouchFLO相关的进程关掉,最终挤出23.71MB的RAM,结论是改善不大。

网络上有传播一种办法,在初始化过程中到安装软件时拔电池的做法,这种方法比较激进,目前还不想试。等有时间刷个纯净版的Firmware,看能不能有大的改善。

5岁时候,因为体弱多病,家里人为了我的健康,想了不少办法,当然也包括了烧香拜佛,当时听说这棵千年银杏树已经得道成仙,很灵验,就带我来祈求身体安康。

大年初二,家里人又提到这件事,为了还愿,27年后我再次来到这颗千年银杏树前。

这颗千年银杏树位于江苏省如皋市九华镇银杏路赵元中学内(原先叫赵家园小学)。

此树距今已有1300多年,高2.8米,周长7.25米,为省二级保护文物,也被誉为华东第一树赵元银杏。

笔记本型号是 T61 7663 ,上面带有一个SD读卡器。因为我装的是 Windows 2003 操作系统,结果SD卡插上去,系统无法识别。

安装了对应的驱动程序:
Ricoh 4-in-1 Card Reader driver
Version: 3.54.02
Release Date: 2008/03/06
7kss55ww.exe 3,301,864Byte Ricoh 4-in-1 Card Reader Driver
http://www-307.ibm.com/pc/support/site.wss/document.do?sitestyle=lenovo&lndocid=MIGR-68053

安装结束后,添加或删除程序程序列表中会出现一个:
RICOH R5C83x/84x Flash Media Controller Driver Ver.3.54.02

设备管理器中,会出现3个新设备:
Ricoh Memory Stick Controller
Ricoh MMC Host Controller
Ricoh xD-Picture Controller
(所谓的四合一读卡器,是不是还差一个?)

到目前为止,系统还是不能识别插入的SD卡。设备管理器中,还有一个黄色感叹号的 “PCI Device” ,查看硬件ID,VEN_1180&DEV_0822

搜索了一下,基本上找不到正规的操作办法。

无意中查看驱动说明,里面有提到:
When upgrading but not clean installing this driver in Windows XP
and Windows XP SP1, the ThinkPad SD Storage and Standard Host
Controller Bus Driver (Q830908) [osda06us] must be installed.
Windows Vista and Windows XP SP2 does not need the ThinkPad SD
Storage and Standard Host Controller Bus Driver (Q830908) [osda06us].

不管如何,先试一下再说,先下载 osda06us.exe
ThinkPad SD Storage and Standard Host Controller Bus Driver
http://www-307.ibm.com/pc/support/site.wss/document.do?lndocid=MIGR-67470
Version: 6.0.4050.1
Release Date: 2007/03/14
osda06us.exe 980,080Byte ThinkPad SD storage and standard host controller bus driver
- SD (Secure Digital) standard host controller bus driver
- SD (Secure Digital) storage driver

手动安装这个驱动的办法:
运行 osda06us.exe 会自动解压缩到 C:\Drivers\SDIO
Click Start, then click Control Panel.
Cick Add Hardware.
Click Next, then select Yes, I have already connected the hardware, then click Next.
Select “PCI Device”, then click Next, then click Finish. –就是黄色感叹号的设备
From the Hardware Update Wizard, select Install from a list or specific location (Advanced), then click Next.
Select Search for the best driver in these locations.
Check Include this location in the search, input the location “C:\Drivers\SDIO”, then click Next.

安装结束后,设备管理器列表中会多出一个:
Secure Digital host controllers
|–SDA Standard Compliant SD Host Controller

SD卡插入后,在磁盘管理器中,会出现一个 Secure Digital Storage Device,也就是哪个久违的移动磁盘了。

贴图一下:

今天南通气温是摄氏 -8~0 度 ,和往常一样,我还是6点多就醒了,可能是天气原因,最近一个月睡眠都很少,基本上6个小时就够了。没事可做,把昨天的行程记录一下:

昨天(1月23日)MU5662次飞机原本是10:10起飞,因为上海那边空中交通管制(广播中这么说的)过来时被延误了20分钟,原本应该是11:45到上海,结果12:05才降落。虹桥机场下飞机后,先去携程柜台拿返程机票(订的是1月30日返厦),然后乘机场938专线到漕溪北路下车,然后乘TAXI到上海长途客运南站。到达上海南站是下午2点,随便吃了点东西(热乎乎的玉米+KFC汉堡),上海到南通的车票是15:05发车,因此在车站冻了个把钟头。

上海到南通的长途车现在统统走苏通大桥,不再走那个另人崩溃的通沙汽渡/通常汽渡了(以往春节回家,等过江轮船,汽车排队就要等2小时),15:05发车,17:45到南通永兴车站(下车后才知道,现在上海南站出发的只能到南通永兴车站,而不是南通长途客运总站)。到南通天已经黑了,打电话给高中同学,结果他还在南京,第二天才会回来,专车接送的方案落空了。只能叫TAXI了,从南通到我老家30公里路程,的士司机要价120,后来还到100,路上还带了两个去平潮的人,走九华-薛窑-江防,不然走越江路,据说更快。还好回江苏前狠狠翻了一下sogou地图,老家这两年变化太大,又是黑灯瞎火的,不然真的很可能不认识路了。

19:00 左右到了家,老爸已经在门口等我们了。红烧肉、蒸馒头、炒青菜,妈妈都准备好了,饭菜还是以前的味道,也一下子唤醒了胃,吃了满满一大碗的饭,吃上热呼呼的饭菜感觉真的很好。

奶奶去通州大李港大姑姑那边去了。
弟弟寒假还找了份工,在江防红星桥一家网吧做网管,晚上不回家。

老婆这次为了满足我回家过年的愿望,跟着我吃了不少苦,真是难为她了,天气这么冷,真的担心她能否受得了。

=======================================

1月30日的返程车票和机票都办妥了,南通到上海的汽车票买的是 8:05 出发的,到达上海最迟也就是11:00,11:30赶到虹桥机场,13:10的飞机,时间上准备充分一些,就不用太担心赶不上飞机。

1月21日,小舅子在莆田仙游结婚。20日晚上6点30分去车行租了一辆车,21日早上7点从厦门出发,22日下午回厦门。

车型:雪佛兰SPARK乐驰(手排)
租金:2日租金+保险+手续费共 245元
汽油费:来回跑了400公里,加满油花了120元,差不多百公里6升油耗
过路费:高速公路65+县道4,来回共140元

总费用:245+140+120=505

车子在高速路上跑到120,方向盘就抖动,基本上都跑在110。

加速性能比较弱,踩油门从80升到120差不多要10秒,所以超车时要注意,如果前方有其他同速小车而且有超车的势头,还是老实在后面等一会儿比较稳妥,免得自己被迫减速避让,还要被后车闪。
