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!

Network Outage Element Watch

Looking at some of my study notes reminded me today, that not all network outages are man made. Elemental power is sometimes at work.

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

Basic and Advanced Cellphone Security Safety

I thought about a time in my life, when my cellphone was used to store all my personal information.  Then security thoughts entered the picture. Today I am laughing at myself. 

National Crime Prevention Council has a nice cellphone safety guide.

If you want more advanced cellphone safety tips Computing Research Association has some good details.

Have fun!
