Does Cisco and Linux use the same type of password hashing?

Q. I know cisco has a version 7 and a version 5; but Linux has md 5, is that the same thing as Cisco's version 5?
Thanks for the insight.

A. Linux (And just about everyone else) uses MD5 or SHA-1 for hashing. I am no Cisco expert, but I would imagine they would use MD5 or some variation of SHA as well, as these are the most ubiquitous of hashes on the modern Internet.

I could be wrong though, I haven't trained for my CCNA yet, I'm just going by what I learned so far.

What is the best certificate in Linux and/or Unix?
Q. I have the intention to master Linux and/ or Unix (I am not sure yet but most probably Linux), so I am searching for the best certificate to study for it, so far I found RHCE and LPIC, I think they may be more.
Please tell me what is the best certificate that would verify my abilities and skills in Linux??
Thanks...

A. Novell also has certifications: http://www.novell.com/training/certinfo/
You can also get certified in Solaris (which is also a Unix-ish OS): http://in.sun.com/training/certification/solaris/index.xml

I'm not sure which certification would be in the highest demand. Certainly Red Hat has the most brand-recognition for the Enterprise. Novell is also well known, and additionally has Netware, which is an alternative to Active Directory. Solaris has a reputation for being rock solid (and notorious for being difficult to administer), but I don't know how much demand there are for Solaris Sysadmins vs. Linux.

What is the best free Chess Training software?
Q. I've seen some very expensive Chess training software. What is the best option for a free software trainer?

A. Hello;

Free software for chess training is pretty rare. I think that it is important to have a good pgn viewer ... I like Winboard in MS Windows and I use eboard on my Linux systems. Winboard is also GUI for playing chess. The newest versions have analysis options.

Beyond that there is Nagasaki, an excellent free chess program.

Interestingly, there is a vast amount of chess help programs on the internet. One of the best is:

http://www.chessvideos.tv/

Is an excellent chess resource. It is a website where chess videos are made many of them are of high quality and the training tips are fantastic.

Free Internet Chess Server (FICS) has chess lectures that can be very informative.

http://www.freechess.org

One of my very favourite chess websites is:

http://www.chessgames.com

It is an on-lline chess community where chess is discussed -- the daily puzzles are enchanting.

There are more, but that should get you started ...
