Peering Test
環境：
Home:
Xlite, 23200@163.22.20.154
Lab:
Twinkle,202.28.99.205
TEST (2008.1.25)
從PSU打到NCNU可以，NCNU打給PSU server就不行。用回撥的也不行。
TEST(2008.1.30)
無法在泰國server註冊。
(沒有開？所以應該也是測試用的server吧？)
猜錯了！因為有收到server給我的404 not found....
TEST(2008.1.31)
寄信給Killy後，OK!
(但是我現在沒辦法接你電話啊！抱歉)
(在家還是無法在PSU SERVER註冊。因為網域不支援？)

[Weekly Report]2007.12.22-2007.12.28
1.Prepare the term projects of VoIP Measurement and Web Technology.
2.Try logging of OpenSER:
2-1. Read the document: OpenSER - Debug and syslog messages
<http://www.voice-system.ro/docs/ser-syslog/ >
2-2. I tried to use the simple log function to record how many INVITE
packets passed my proxy server. Try and error, and finally it worked!
(HAHA!) I think I can combine the result of the log file with my term
project topic, MRTG , to get a visualized report of SIP call flow.
2-3. The second try of the log function is to log how many successful
call have established. I discussed with Wen-Jen, we think maybe we can
log how many ACK packets. I put the log function in somewhere in the
main route, but it didn't work. The task is not finished.

[Weekly Report]2007.12.15-2007.12.21
1. Settle down the SIP Fluoroscope System on three servers:
1.1 On my own Linux server, it runs well. But there is still one
problem. The PHPGD module cannot be loaded well, so I can't not move
on the path to draw the flow of call using MRTG.
1.1.1 This week, I found that I should use sudo to compile the C
program captures packets. (Reply to the teacher question in the last
weekly report)
1.1.2 Before this week, I compiled, and failed, and I even didn't know
I failed.
1.2 On the ms11 server, it (still?)runs well.
1.3 On the iPBX server, the system can capture the packets,and store
them in the MySQL database. The webpage can show the packets, but not
so-called real-time. There must be something wrong, and the key
problem might be AJAX. Still debugging. I use a useful Firefox
plugin,Firebug, to debug the javascript code. The error message shows
that there is a function in Sajax not defined. But I check the Sajax
is the same as others on the other Linux server(my own server).
2. Struggle with the logging of OpenSER:
It must seems very simple for the demon(取其「高手」意), but I am 苦手(日語). I
tried to insert some log functions in the OpenSER configuration file,
but the message didn't show up in the log file. I must put them in
the wrong places. I walked around the forum, and get a
tutoria<http://www.voipuser.org/forum_topic_8040.html >(I would like to
call it a reading queue for knowing OpenSER). And I consulted Wenjen,
he advised that I should read the OpenSER Core Cookbook and "OpenSER
Pseudo-variables" document to know how to program in the configuration
file. There are too many things on my TODO list.

1.Implementation task:
1-1.Try to compile the Sipfluoroscope system program in Linux system.I
compiled with wrong option and failed to link the need library and get
right execution file. It is ok now! But it is very strange that the
mysql database cannot get the data capture from the the Sipfluoroscope
system.
1-2.Try to get the the Sipfluoroscope running on the ipbx.ipv6.club.tw
server. As you saw, I am not very familiar with the *UNIX command and
system.

Weekly Report
1.SIP server using OpenSER:
Authentication setup is ok!
2.SIP.edu document reading:
SIP.edu Cookbook reading task is over.<http://mit.edu/sip/sip.edu/ >
------
Reply to your instruction(last weekly report reply):
>Is "SIP Fluoroscope" running on iPBX now?
Ans:Not yet.
I need time for this task.
>You must have gotten your OpenSER running.
> Try to figure out its support on logging.
>(Similar to SIP Fluoroscope, but not so tedious.)
Ans:When my server reboots, the OpenSER restart automatically.
>Have you finished reading SIP.edu documents?
> Please prepare a webpage to describe our system like
>http://www.ethworld.ethz.ch/technologies/sipeth/notes
>(You may also refer to the "Notes" of other universities
>to prepare ours.)
Ans:I will explain this task below(in Chinese paragraph).
>Let me know the progress of the above items, so that we can discuss
>the draft of your final report.

ps.因為學校信箱不太穩定，所以本週週記改由Gmail信箱寄出，以後也是。

親愛的老師:
因為家裡有點事，
這週四晚上我決定隔天旁聽完資網課後回家一趟。
還很樂觀地以為回到家大概才下午三四點，
應該可以很悠閒地看著太陽下山完成週記，
結果這週屏東人特別愛家，
台中朝馬國光客運車站三分之一以上的人都是要搭車回屏東的乘客，
國光客運在下午四點還特別加開加班車把熱血愛家的人們運回家，
不過我連加班車都沒坐到 回到家時都已經晚上八點了。
心裡還是惦記著週報沒寫，
看了一下在客廳的無線router燈是亮的 ，
想說一會兒跟家人寒喧完就可以寫了，
可是媽媽突然說因為家裡平常根本沒人用電腦(我和妹妹都在外地)
所以他把ADSL網路給停了......
這是我這週五的經歷 ，也是週報沒有準時交的原因。
這兩個禮拜我的工作日誌上的空白欄很多(我將一天分成三個區塊來紀錄進度)
除了因為一直感冒(running noise)還有其他的原因，
有家裡的事和自己心裡的事，
還有，我的SIP.edu for NCNU簡報及建置網頁的專題報告都還沒動是因為在看了它校的note網頁後，
覺得我們實驗室SIP server的作法跟正規的機制好像差很多，
那天下午跟學長討教 覺得我們實驗室好像只有把兩個資料庫用一個flag(boolean type)結合，
或許是我還沒了解透徹也或許我們真的是用非常簡化的方法去implement SIP.edu mechanism，
我問自己 為什麼不去搞清楚，
答案可能是我覺得我已經懂了，
可是兩者機制的確不同 報告該怎麼寫，
就是這樣顧慮東顧慮西 所以拖拖拉拉沒有進度，
SIP.edu cookbook的網頁資料從目錄結構到最後我看了好幾遍， 但是有看沒有懂， 所以不敢寫在週報裡。
