OK, OK, so what's bottom line?

So, bottom line is, moving from CAS-3 to CAS-2 will offer a percentage performance increase in low single digits for most applications. Programs which are known to be memory intensive (you gamers might know of some...) will see best improvement. The other thing to keep in mind is that CAS-2 memory will run FASTER ( some review sites have taken it to 160MHz!) than CAS-3 memory. So, if you're thinking of overclocking your system (now or in future), CAS-2 is your best bet for speed and stability.

So...

Buy CAS-2 if [1] you want to wring last bit of performance out of your system, or [2] you're thinking of overclocking, either now or in future, or [3] it costs same as CAS-3, which it sometimes does... Otherwise, CAS-3 memory should meet your requirements

Now we'll telnet into Cash and concatenate sue.pub file into /home/named/.ssh/authorized_keys file.

Cash$> pwd /home/named/.ssh Cash$> cat sue.pub >> authorized_keys Cash$> exit Connection closed. Johnny$>

Let's recap what we've done so far. 1) We've created public and private keys on Johnny. 2) We've ftp'd public key file, sue.pub, from Johnny to Cash. 3) We've telnetted to Cash, and concatenated contents of sue.pub into authorized_keys

We're now ready to manually login from Johnny to Cash using ssh.

Johnny$> ssh -i /home/boy/.ssh/sue named@Cash The authenticity of host 'Cash (xxx.yyy.zzz.aaa)' can't be established. RSA key fingerprint is 65:11:7d:ef:ed:a3:cc:34:d1:b5:ba:c9:16:22:31:23. Are you sure you want to continue connecting (yes/no)? yes ================================================================

*** NOTICE TO ALL USERS ***

================================================================ Cash$>exit Connection to Cash closed. Johnny$>

Now on Johnny, create a shell script called 'boynamedsue.sh' with following one line of contents and chmod script to 777.

ssh -i /home/boy/.ssh/sue named@Cash /usr/bin/ls -l

Next, execute script on Johnny.

Johnny$> boynamedsue.sh ================================================================

You just executed a program on Johnny, that logged into Cash and ran a program (unix 'ls -l').

The next step you'll want to take is to replace '/usr/bin/ls -l' command in boynamedsue.sh program with path and name of program that you want to run.
