This is an announcement about a new LUG in CREC, Kerela, India.
We run a LUG in CREC (Calicut Regional Engineering College, Kerela,
India) called CREC-LUG. Although there have been Linux users in the
college since about 1995, paradoxically the LUG was founded in Nov 2001!
That partly explains why we haven't had any meetings yet, the other
reason being the exams :-/.
The DNS to our server (called tux.reccal.ernet.in) is shaky and slow
(almost like the whole ERNET), so the site better be accessed at the IP
address. Mail however would come through.
Lug Name : CREC-LUG
Co-ordinator : aaditya sood <ec98310 at matrix.reccal.ernet.in>
Mailing List Url: http://202.41.105.20/mailman/listinfo/lug
Mailing List Subscribe : <lug-request at tux.reccal.ernet.in> or from the Mailing list Url
Mailing List Archives : http://202.41.105.20/pipermail/lug
Lug Website : http://202.41.105.20/
First Meeting : Sometime in Jan 2002
Local Resources : A mailing list+website+~150 people:)
So any of the alumni of the college, anyone near Calicut (or anyone
at all:)) is invited to join. Just send a mail to me for more info.
Happy hacking!

Subject: MATtool 0.28 released
Date: Wed, 23 Jan 2002 08:50:02 CST
Hi
I'm proud to announce a new release of the Monitoring and Administration
Tool (MATtool). This version has:
- Console now shows when one or more hosts is down in a group.
- Added command macro. Frequently run administrative commands can be run with a few clicks.
- Added the ability to resize the panes.
- Added an administrative log so you can keep track of any system changes.
and lots more...
See the MAT web site for a full description of all the changes:
http://www.ee.ryerson.ca/~sblack/mat
It contains screen-shots, as well as descriptions of MAT's functions.
Below is a description of this release of MAT.
Monitoring & Administration Tool (MAT)
--------------------------------------
MAT is an easy to use network enabled UNIX configuration and monitoring tool.
It provides an integrated tool for many common system administration tasks.
The GUI interface hides much of the differences between UNIX varieties in a
heterogeneous environment. The straight forward interface hides the
complexity of the underling configuration files, allowing many of the mundane
administrative tasks to be safely delegated to others. From a single MAT
console you can manage every UNIX host on your network where the MAT agent
is installed.
Tools:
MAT is a time saver. MAT provides many of the tools a System Administrator
needs during the day, including DNS, NIS, Backups, and Replication. A
powerful feature is the ability to run a command on many hosts at once.
For example a new group could be added to all machines just by doing a select
all, then adding the new group. For generic files a simple editor window is
provided, with this the configuration files for a sites web servers could be
changed, just by editing one.
MAT includes a flexable replication tool for the distribution of files from
a single machine to up to 64 other machines. Complete control of file and
directory properties is provided, as well as bandwidth saving incremental
replication, where only the changed files are replicated.
MAT includes a Backup tool for SCSI tape devices. Tape catalogs are stored
online, so file retreval is easy. Hosts are backed up in parallel, and a
graphical restore tool makes restores easy.
MAT includes a command replication tool, allowing a change on one host to
be made on all selected hosts. By selecting several hosts or groups MAT will
run the next command on all of the selected machines, so changing a password
would cause it to be changed on all hosts. Use with care!
Monitoring:
MAT provides two kinds of monitoring, namely current status, and historic
logs. Through the Status screen you can inspect the current state of the
machine. The MATd screen gives you access to historical data on the machine.
It lets see how heavily loaded you machines are, how the network interface
is performing, and many other parameters.
The MATd daemon allows you to specify alarm thresholds. It can watch your
FTP and Email server for failures. It can watch your disks from getting full.
It can watch the CPU use for thrashing, and several others. You can taylor
your response to each alarm situation, including taking corrective action.
Administration:
The administrative tasks can be delegated to other individuals. A MAT user
can be granted as much or little access as you require. Users can be given
different access rights on all your MAT hosts. Every MAT user can be managed
from a single console. A log file records all the MAT commands issued on a
host, and is viewable from the MAT console.
MAT also includes easy to use interfaces for common UNIX configuration tasks:
User administration
Hosts
Email Aliases
Mounted filesystems
Crontab entries
DNS client configuration
Login message (motd)
Services
Exported (shared) filesystems
DNS domains & records
Most NIS records
Syslogd entries
MAT allows you inspect many of the common system parameters including:
All syslog files (TK 8.0 recommended for this)
Routes
Processes
Lastlog
Diskspace
Exports
The monitoring deamon MATd runs scripts for monitoring of:
Network Connectivity (through ICMP)
Required Processes
Disk usage
CPU use
Run queue
User logins
FTP server status
SMTP server status
Network Interface Activity
SWAP, and Memory use are monitored in the Linux version.
A simple plotting tool allows you to graph the various monitored
parameters. The monitoring scripts are written in Perl, and should
be easy to customize and expand. The MAT probe has been updated to
display it's current status.
Requirements:
=============
For the MAT agent you need a UNIX machine running:
Linux 2.x (glibc)
Solaris 5.x
IRIX 6.x
HPUX 10.20 or 11.00
The Console requires Tcl/TK on at least one host.
Perl is optional
License:
========
Free for single host installations, otherwise it is shareware.
