Update on NIS/Home and next meeting

[JJ Neff]

	Thanks to everyone who came and made the meeting such a success.  I hope
everyone left with a littel more info than they came with, I know I did.

I am now running NIS exclusively at home and have setup my wife and my home
directories on the server (now I need a bigger SCSI DRIVE! anyone have a 20Gb
SCSI drive laying around taking up space? :-)  she just called me and reminded
me I forgot to make sure the printer worked for her.  Oh well!

BUT since the Home directories are on the server as well as Staroffice I have
more room for GAMES on /opt  YEAH!!!

I also may have found out what was causing my random lock-ups/NFS freezes/SAMBA
stoppages and assorted miserable performance.  My / was at 100% utilization. A
scan of the /var/log/messages told me that NFS and Samba and just about
everything was trying to write to /var/<something> and failing.  Well it
appears SNORT was running and wrote 1.7 Gb of data to /var/log/snort!  once
cleared up (and snort removed) / dropped to 11% utilization (over 1.5 Gb freed
on 2Gb drive!)  Thanks to Bob M for some more cmd line tools to quickly find
offensive disk space hogs.

****************
ls -s <lists files and their sizes only

find / -xdev -size 1024K -print  < this will find all files on the currect FS
(partition) that are taking up more than a MB, useful becasue my /usr and /home
were on other partitions and not involved.

du -sk * < my favorite! finds the sum of all subdirectories/files in the
current file path and returns the total size of all subdirectories in current
directory (ie if in /var it will return total size of all directories in var,
if /var/log the biggest I go into /var/log do it again and find the biggest in
there!)

df -h < Human readable Disk Free - best for seeing a BIG PICTURE view to see if
your careful removel of files is actually freeing up space.


To find the largest files I started with du -sk * in / and drilled down from
there.  Thats how I found the 1.7 GB folder in /var/log/snort.  Be careful of
any app that writes continuous logs (and keep logs on seperate partition if
possible!)

ABOUT NEXT MEETING:  

MArch is always rough because of St. Pat's and Palm Sundae (this holy day of
obligation is to commemorate those who are too poor to get cones and have to
eat ice-cream out of their hands, Oh well it's been a long time since I went to
church :-).  I do not object to meeting either the 17th or 24th.  Although on
St. Pat's downtown may be wacky and on Palm Sunday everyone will be carrying
palms and I've always feared those things (childhood tragedy :-)  

Anyways what your feeling.  Speak up and lets decide on the 10th, 17th or the
24th.  Remember the day also will include LAN gaming as I will hopefully be
able to stay late this time!!!!   Maybe we can even walk over to a downtown Pub
to really get the St. Pat's spirit! but only if they have T1 access !
