Network Diary: Expect the Unexpected with Social Media

Can't wait to share good microblog links.. think I will log on to Twitter and share. Oh No!! ...
"Twitter Ongoing denial-of-service attack. We are defending against a denial-of-service attack, and will update status again shortly." http://status.twitter.com/

Well, perhaps I will check out Techfuga.com.
Oh My!!! " Techfuga.com offline for months to plan for new platform site Joao"
http://www.techcrunch.com/2009/07/06/techfuga-is-taking-a-couple-of-months-off-delivering-breaking-tech-news/

Hmm.. guess I will check out my favorite networking site Cisco.com.
"Cisco.com experienced an outage of over two hours on Tuesday " http://www.networkworld.com/community/node/44133

Right then, maybe I will check out firefox e-store.
" Mozilla shuts Firefox e-store after security breach"
http://www.networkworld.com/news/2009/080509-mozilla-shuts-firefox-e-store-after.html

Right then.. guess it seems Murphy's Law is in full play this week.
If it can happen, it will happen.

Electronic Light Puzzle Game

Linux Network Code: Big Endian and Little Endian Snack

The TCP/IP protocol is "Big Endian"processing. How does a "little endian" processor read the packets sent from "Big Endian"?

Little Endian reads CPU register value (backwards or bottom-to-top)

Big Endian reads CPU register value (forwards or top-to-botom)

This means Byte Order "functions" are needed to switch (convert) between big endian and little endian.

Linux, BSD and Solaris use the following functions:

hton = host-to-network
ntoh = network-to-host

s = short = 16 bit integer
l = long = 32 bit integer
ll= double = 64 bit integer

Function Code Sample:

htons()
htonl()
htonll()

ntohs()
ntohl()
ntohll()


This means if the routing processor is "Big endian" and the sending or receiving processing code is "Little Endian" The above byte order "functions" are required to switch (convert) between Big Endian and Little Endian. If no Byte Order "Function" is present then it will arrive as unreadable garbage to the processor.


Hope you enjoyed this Linux Network Code snack!

Security network weapon of mass instruction

Icons.apnic.net has current and legacy IPv6 information links. What makes the site special? The current updates and contributions from networking specialist are valid with substance.

For example the following link was from Icons.apnic.net.
The U.S. DEPARTMENT OF DEFENSE High Performance Computing Modernization Program
Information Assurance Awareness Course  

This course was so nicely done, I decided to give a visual summary video of less than 60 seconds.

Enjoy!

Linux Attributes:Undesirable Access Security Snack

Why did I choose the handle "lsattr_nix"?

The "lsattr" command displays the attributes of Linux files EXT2.

Linux files that have the flag set for "Immutable" can not be modified or deleted, even by "root" unless the flag is removed.

The immutable attribute can be identified using "lsattr".

If "i" is the out put for the attribute listing of a file it is unchangeable or immutable. See the picture above for an example.

Enjoy!

Internet Network Traffic Packet Archive

Some packets, I just wont see every day. The Internet Traffic Archive has 4 million-packet traces of LAN and WAN traffic, 30 days of wide-area TCP connections, Six months of Web client traces and more.

The traces are a very helpful review of network traffic that I do not normally see on a daily basis.

It has been interesting identifying and reading packets that are slightly irregular.

The Internet network traffic by ACM SIGCOMM is at http://ita.ee.lbl.gov/html/traces.html
