Videoconferencing @ MBZ

We finally got Videoconferencing to work with our system. During the MBZ (Movement for Better Zamboanga), we were able to host videoconferencing for almost 2 hours between ADZU and Mozcom Manila, Main Office. Thanks to Jessmike of Mozcom and Dr. Bill Torres for the setup and service. We used Polycom V500 and enabled ports 3230-3235 and 1718-1720. We brought down the entire 4Mbps bandwidth Internet link of the ADZU community to give it to the videoconferencing which requires only 128kbps. This improved the video output of the videocon. I will probably do a traffic prioritization next time so as not to interrupt the browsing of ADZU users. ;)

DNSSTUFF Quick URL query

Here is the script for fast accessing to dnsstuff services.

To check for spam list of an IP you type:

http://www.dnsstuff.com/tools/ip4r.ch?ip=

Example replace to check it in their SPAM Database. Like,

http://www.dnsstuff.com/tools/ip4r.ch?ip=122.254.193.163

To check the whois service you use:

http://www.dnsstuff.com/tools/whois.ch?ip=221.236.101.138


Summary of the DNSSTUFF.com website are the following:
1] ip4r.ch
2] whois.ch
3] ptr.ch -- reverse DNS
4] ipall.ch -- more detailed than whois
5] ping.ch
6] tracert.ch
7] dnsreport.ch

http://www.dnsstuff.com/tools/dnsreport.ch?domain=yahoo.com

8] lookup.ch
where type could be:
a] MX
b] A
c] NS

http://www.dnsstuff.com/tools/lookup.ch?name=yahoo.com&type=MX

VMWare after updating/upgrading Ubuntu

Need to do the following:
1] re-install VMWare server by running the script:

sudo ./vmware-install.pl

2] Install the C Header files with

sudo aptitude install linux-headers-`uname -r`

3] Specify the location at

/lib/modules/<>/build/include

:)

Catch the IP in the httpd.log

Catch the ip of clients from error_log files... needs improvement

grep '\[client' /var/log/httpd/error_log | gawk '{ print $8 }' | sort | uniq -c | sort -nr


This script counts the IP who has the most occurrence of the substring specified.

grep "newthread&fid" /var/log/httpd/access_log | gawk '{ print $1 }' | sort | uniq -c | sort -nr

You can modify which distributions by taking note of the link and modifying your script. You need also to take note of the last page.
