Server latency

Posted 10-27-2011 at 08:26 AM by sag47

I wanted a quick and dirty way to determine server latency on my Kubuntu machine. This just parses simple output from ping and provides only the time values.

Code:
for x in drexel.edu google.com;do echo -n "[$x]: "; ping -c 1 $x | head -n 2 | tail -n 1 | awk '{split($8,arr,"=")} END{print arr[2],$9}';done
Output
Code:
[drexel.edu]: 0.576 ms
[google.com]: 6.23 ms
You can put as many servers or IPs as you want in the for loop to get a comparison....

Recursively generate MD5 checksums

Posted 10-26-2011 at 09:53 AM by Garda
Tags find, md5, md5sum, xargs

I wanted to generate MD5 checksums of a whole bunch of files in a directory. It turns out that this is not as straightforward as it should be. IMO it should be completed with: md5sum -br *

Unfortunately it was not as straightforward. I found this blog entry after searching for a while and adapted this to what I needed. To generate checksums, I used the following:

Code:
find . -type f -print0 | xargs -0 md5sum -b
(Note: for the above to work, "cd"...

day one (a buggy debian installation)

After crying a little bit more, I decided to return to the Debian web site and try to find another iso that actually installed something I could use. (needless to say, their website is very difficult to navigate, and their distribution layout, confusing).

http://cdimage.debian.org/debian-cd/6.0.1a/i386/iso-cd/

Finally, I made it, I downloaded the first CD from that directory (apparently all you need is the first disc, and the other discs are there to confound dozers...

So, I guess day one started a long time ago. I happened to check the classified paper (because my dad still reads newz paperz, what a lamer) and saw two local businesses advertizing a need for Ruby on Rails programmers. I happened to like one of them a lot(they sell food, but no further details shall be provided to protect their delicious identities). So I said to myself, "I'm going to figure out what Ruby on Rails is and then do that for money."

Upon further investigation,...
