- Added a new file management functions,
including a complete new file management UI.
The file operations are also performed on all the selected
hosts. Copy, move, delete, change permissions,
run, edit files etc on one or 100's of hosts all from a simple UI.
- Added simple hosts file locking. This allows running
of multiple consoles from an NFS installation without damaging the hosts file.
- Added support for alternate host and host group icons.
You can now use more descriptive icons for hosts,
blade systems, and host groups.
- Added Ping probe to set of probes. With this a host
can ping a list of other nodes to see if they are
running. The probe result will affect the hosts
status (temperature). The list of hosts to ping
is set in the Instance Arguments property.
- Added a DNS probe to the probes. If the host is a
DNS server, has /etc/named.conf or /etc/named.boot,
then a DNS probe will be added.
The probe will by default try to resolve the hosts
name, but a list of hosts can be used to test internal
and external host name resolution. The probe
result will affect the hosts status (temperature).
The list of hosts to resolve is set in the Instance
Arguments property.
- Fixed deletion problem for MATtool hosts
which were part of more than one group.
- Fixed the Auto Probe so selected hosts would not be
cleared when the probe updated the host status.
- Fixed Email formating problem in MATd monitoring tasks.
Version 0.30
- Ported MATtool to Solaris X86.
Solaris X86 is an excellent OS for clustered computing. With the
right hardware IMHO Solaris X86 requires less administrative effort than
Linux., so it is now supported by MATtool.
- Fixed install problem which
prevented creation of command macros.
- Fixed install problem which
stopped macros from running as other users.
- Fixed macro environment
creation problem.
- Fixed problem with xinetd
flags for Redhat users.
- Fixed upgrade problem with
IRIX.
- Changed the password field
for systems with shadow passwords for compatibility with other tools.
- Finished backend work to
support file operations for something like windows explorer. Click
on Agent -> What's coming in the console to see a preview.
Version 0.29
- Added a new scheduled task
to reprocess the command relay tasks on any host which failed in a previous
try. For example if a task was run on 100 hosts, but 2 were down,
the command relay host would retry to run the task on the 2 hosts, at in
interval of every hour, or until it succeeds, or the maximum number of
retries is exhausted. It does not retry when the 2 hosts cannot be
pinged.
- Added a New UI for about
so a user could retry running a task on failed hosts on demand, or prevent
the command relay from trying to rerun the task on the down/failed hosts.
- New OS command macros have
been added. Import your own admin scripts into MATtool, and
let it take care of distribution, and running over many hosts at once.
- Changed the data gathering
so it does not use a persistent process, so resource usage by Matd appears
smaller.
- Changed Matd log cleaner
default timeout to 300 seconds. Previous value would cause the job
to fail while waiting for the other tasks to shutdown.
- Changed the file sorter
so it is much faster.
- Changed the way command
relay user credentials were stored. The previous method would have
allowed an admin to spoof a command relay task.
- Rewrote the command parser
so reduce replication of functionality. This could be a source of
bugs in this release.
- The maximum number of hosts
in a replication/backup host group is increased to 128.
- Moved the macro editor under
the Command Replication area.
- Added a dialog to verify
that a command should be run on all selected hosts, to avoid accidents.
- Added an upgrade summary
in case some hosts were down during the upgrade.
- Fixed the upgrade so if
only one host was selected it would upgrade that host instead of localhost.
- Fixed problem with command
replication which caused some hosts to not get the commands when there
were over 40+ hosts selected.
- Increased default warning
and error thresholds for the ethernet, runqueue and memory use alarms.
- Fixed the matd, so it would
work out the location of the MAT directory without needing to be started
with the full path.
- Fixed bug that would leave
shared memory when all matd processes had died.
- Fixed logic error in matd
which could cause multiple monitoring tasks of the same type to be spawned.
- Fixed bug where moving a
host on the screen would move another in a different view.
- Fixed buffer overflow in
Matd task command parser.
- Dropping support for Solaris
2.5.1. The minimum is now Solaris 2.6.
Version 0.28
- Fixed problem with command replication which
caused some hosts to not get the commands when there were over 160 hosts
selected.
- Added the session prompt at the console
startup.
- Added a host down indicator to the host
groups. It indicates when one or more hosts in a group is down.
- Added the ability to resize the different
panes of the console independently.
- Added the ability to create OS command
macros for commands that are commonly run over many hosts.
- Added an administrative log. Changes
and fixes applied can be logged in an append only log, as a record of what
has been done on a host.
- Added a Host Notes section to the System
Info section. This is for storing host information such as config, serial
numbers, warranty info etc.
- Changed the Search so it would select
the line matching the search.
- Changed the File Editor to stop users
from trying to type the file name in the directory box.
- Fixed Command Relay debug info appearing
in the Command Output pane.
- Fixed the Save Host Locations so it would
not strip out the host descriptions.
- Removed caching of host status. On double-clicking
a host it will now check the status of the host every time.
- Fixed cummulative bar graph so it will
draw without requiring user to select type.
- Fixed the installation so it will get
the directory correct for alternate install locations.
- Fixed the upgrade script so it will try
to stop MATd before upgrading, then restart it.
- Fixed the host editor to stop it converting
host group names to all lower case.
- Fixed the host warning and error indicators
so they would reset.
- Fixed pointer under-run in many file
parsing routines.
- Fixed IRIX upgrade procedure, so it will
properly extract the upgrade package. This means upgrades from the console
should work on IXIR in versions 0.28 and higher. The timeout can be ignored.
- Increased default warning and error thresholds
for the ethernet, runqueue and memory use alarms.
Version 0.27
- Added patch sorting to Solaris patch inventory
- Added the ability to run OS commands
as an alternate user.
- Added $USER, $HOSTNAME, $HOME, $PWD environment
variables to the Run OS command environment.
- Added the ability to send OS command
output to command output window instead of redirected to a file.
- Added the ability to upgrade all hosts
in the cluster just by doing Select-All and Upgrade/
- Added the ability to save the environment
for OS commands.
- The install script now has a no questions
install Open the script to see how to use it.
- Changed the MAThosts editor so the parent
box (group) displays the parent group name instead of the id.
- Changed the command relay so it will
send the commands to up to 40 hosts at a time.
- Deleting a monitoring task from MATd
will remove the icon on subsiquent visits to that host.
- Changed the monitoring thresholds so
out of the box it would not generate too many false alarm alerts.
- Fixed the command relay so it would not
block on connecting to dead hosts.
- Fixed the console blocking problem when
hosts were down.
- Fixed a multi-host command Select-all
problem when the error or warning thermomitor was showing.
- Fixed command replication to work with
more than 20 hosts at a time.
- Fixed NIS user add so "0" was removed
from login entry.
- Fixed NIS so after a user add it would
not flip back to the /etc/passwd.
- Fixed NIS user editor so adding works.
- Fixed Solaris reboot and shutdown functions.
- Fixed install.agent script. Removed 0x0d
characters.
- Fixed several errors in the Mathost editor
- Fixed a right-click problem with undefined
$labels
- Fixed upgrade message which displayed
RAW file extraction problem message.
- Fixed division by zero error messages
in the line graphs
Version 0.26
- Added the ability to run commands on one
or more hosts at the same time. Included command history to the command
status on the hosts could be seen. In the next release this will
be used to replay commands to hosts which were down the first time.
- Added resource status "temperature gauges".
These show when a monitored object is in the Warning, or Error state.
The resource status is propigated to the lowest display level, so a host
group will show an error when a host in that group has an error, or a host
in a subgroup of the current group has an error.
- Added the ability to specify the period
of historic data to graph from a host. This makes the graphs faster.
Added X scaling, and different graph types.
- Added Reboot and shutdown support, for
one or more hosts at once.
- Added status support to the Auto Probe.
This is used to show when a hosts is in trouble i.e. when one or more monitored
resource is in warning or error status. The temperature gauges, an
upcomming web status display rely on this.
- Added System inventory support for some
of the OS's. It shows hardward and software on a host.
- Added TNM module. This adds multi-protocol
support to TCL. In this release it is used to adds SNMP traps, and
syslog messages to the resource error and warn alarms.
- Added nsswitch.conf support.
- Added SMTP (Email) Server monitoring
script.
- Added POP3 Server monitoring script.
- Added FTP Server monitoring script.
- Added HTTP Server monitoring script.
- Added Right-click actions for historic
objects.
- Added File sorting to the file lists.
- Fixed polling bug in Tcl monitoring scripts
which caused two monitoring scripts to be called within 1 minute even if
the interval were > 1 min.
- Fixed New button for new MAT hosts.
- Fixed IP Scanner, to allow start and
stop IP's to be the same.
- Fixed backup host file list selection,
to allow selection from other hosts.
- Created multi-threaded matd for the TCL
monitoring scripts, but shelved it, because of lack of support on HPUX
10.20
- Created hooks for a web status display.
The next release will use these to show the hosts/groups status on a web
browser.
Version 0.25
- Added an IP scanner to detect MAT clients
on a network and automatically build the console hosts file.
- Added a host status scanner to the console.
This goes out and tests each host known by the console. If a host
is down, when the host view is redrawn the host icon will indicate that
the host was unavailable.
- Re-wrote the console iconic display section.
This was needed to support the new concept of managed objects. Each icon
now represents a managed object. This will be used later to speed
the development of new management functions. Today it allows users
to make their own "status" objects. These report the current
status of some thing.
- Added a startup splash screen.
It ain't pretty, and a better one is welcome.
- Added the ability to run MATd tasks as
a non-root user.
- Fixed memory leak in console code.
It used to re-create an image as a user switched between hosts. The
images are now loaded at startup. The display is now MUCH faster.
- Added a work-arround for the xinetd used
in Redhat 7.0. Xinetd was not passing argv[0], so it will be taken
as argv[1], if provided.
- Added new graphing and display functions.
This makes extending the console with your own status, and historic functions
easy.
- Dropped Linux libc 5.x support.
Many strains of Linux are using glibc instead. Lost the hard-disk
on my libc 5.x machine.
- Dropped SunOS 4.1.x support. My
Sun SLC died.
Version 0.24
- Changed host configuration code so
it would be faster for large sites.
- Changed the immediate replication and
backup so they would not terminate when the console connection closed.
- Re-coded MATd UI to support Tcl scripts.
- Added a new UI for creating TCL monitoring
scripts.
- Added namespace graphing code for graphing
data gathered from monitoring scripts.
- Added introspection into the matagent.
The remote host not tells the console what it can do. This allows
users to add their own scripts.
NOTE: This will cause an
error to appear when using the status section of a new console with on
old matagent.
- Embedded Tcl interpreter into MATd.
MATd can periocically run Tcl scripts to gather performance information.
- Embedded Tcl interpreter into matagent.
- Limited encryption to 128 bits.
Higher encryption may have export restrictions.
Version 0.23
- Added the ability to replicate files to
alternate locations. For example replicate /www/htdocs/ to /usr/local/webroot/
or /opt/Perl/perl_5_005 to /usr/local/bin/perl.
- Added an encryption library for secure
file replication. It can have from 32 to 448 bit encryption.
- Added the ability to run the console
from a browser. The TCL browser plugin from Scriptics is needed, and can
be downloaded from http://www.scriptics.com. Invoke the browser from the
bin directory, and rename mat to mat.tcl.
- Updated the User account UI. It is now
more intuitive. Added default account values. Added locking reasons i.e.
reasons why the user account was locked.
- Fixed shadow password locking/unlocking
for both local and YP shadow files.
- Fixed post User add/modify so it would
not fail if Perl was not available to run the AddUser, or ModUser scripts.
- Fixed potential buffer overrun in group
modify function.
- Fixed password change error 702. Can
now change password from login UI.
- Fixed host add bug which would cause
duplicate icons to appear.
- Fixed file permissions change when add/mod/delete
an entry. It now keeps the file permisions it started with.
- Changed MAT user UI so you can now edit
the root user.
- Changed local password editor, so you
can modify root's password entry, but not delete.
- Changed the command output window so
it is part of the main screen, on a suggestion from JN.
Version 0.22
- Added multi-host commands. A single MAT
command can be issued to one or more hosts. This is a real time-saver.
Example:
-
Change the root password on all machines at
once!
-
Update resolv.conf on all your machines with
a few clicks!
-
Edit a file on one machine, and MAT will copy
it to all the others.
- Added a more capable mail alias GUI. This
one permits alias entries that are more natural.
- Fixed bug introduced in 0.21. The 0.21
version had many changes to the command syntax, to allow commands to be
issued to many hosts. The changes broke:
-
MAT passwords could not be changed or added.
-
The modify button did not work for some commands,
but double-clicking did.
-
Install.agent script was missing/broken in
the release files, causing it not to install, or MATd to fail.
-
Shadow password files were not being updated.
- Fixed Solaris upgrade bug. Upgrading a Solaris
version of MAT now works correctly.
- Fixed MATd core dump. A configuration
file was missing from the install.agent script.
- Fixed error message from the file edit
window when you double-click on a file.
- Fixed shadow password locking for local
password/shadow files.
- Changed the mouse bindings on the host
display. The right-button now selects a host or group. The middle button
now has the new, and about items.
- Changed autoLogin read/write to readn/writen.
- Fixed fgets return type compares, and
casting.
- Fixed shadow password locking/unlocking
Version 0.21
- Added a restore GUI. The GUI gets
the backup history from the tape server and displays it in a logical
fashion. It uses the online catalogs so you can see which tape is
appropriate.
- Added ability to drag host icons into
logical groupings, and a save location button so it would recall where
you placed the hosts icon.
- Added a new host grouping scheme.
This permits grouping of hosts into logical/organizational groups.
Updated to MAT host GUI to create them.
- Added code to select console fonts based
on OS. This was needed for Win 95/NT.
- Added backup history logging. This
was needed for the restore GUI and will be used for tape management.
- Added code so new MAT host will now try
to determine the OS type for newly added hosts.
- Added MAT deamon logging for debugging.
Invoke with: /var/mat/bin/matd -d {0|5|10|50}
Was undocumented in version 0.20.
- Added code to catch unfinished commands
from the console. These are generated when the user does not wait
for the command output before issuing another command. Problem is
more apparent on slow machines.
- Added code to support MAT license management.
Fore future use.
- Added file editing for arbitary files.
A GUI browses the files on the remote host, and retrives the file for editing.
- Changed the Crontab and Mount command
set. This is needed for a future feature which will allow commands
to be issued across many hosts.
- Changed NIS code to allow large groups.
- Changed Backup GUI, so it would be more
intuative.
- Changed Replication GUI so it looked
better.
- Changed TAPE get cat command so
it accepts the real volume number, and not (N - 1)/2.
- Changed log so it records the user as
well as the action.
- Changed the "cmd" program so it would
accept commands as arguements, eg running:
./cmd CON
get matpass
will get the MAT password file.
This will allow scripting MAT functions.
- Fixed MAT upgrade feature. You
can upgrade clients directly from the console without having to login to
the host.
- Fixed buffer overflow in timestr.
It was too short in all functions.
- Fixed bug in mount code which caused
user scripts to run before changing file.
- Fixed bug in mail code which caused newalias
script to run before changing file.
- Fixed month field in MATd date stamp.
- Fixed time-out bug in backup code.
This caused the backup to stop on files greater that 40Meg.
- Fixed bug in directory restores.
It would not restore directory contents if several host were backed-up
at the same time.
- Fixed MAT host editor. Changing
the services offered by a host will not erase the host type now.
- Fixed logging bug in tape library.
Log file was not always opened.
Version 0.20
- A HP UNIX 10.10, 10.20 port is now available.
It includes most of the functionallity of the other ports. It does
not have the user-added-functions support yet., because it does not seem
to have dlopen.
- A file/directory replication module has
been added. It allows a replication server to replicate its files
to up to 64 clients. Replication is done in parallel, and can be
set to only replicate changed files. This is a nifty module.
It can use as much network/disk bandwidth as you've got. It's
- The GNU libc is missing the crypt function.
MAT used this function for it's passwords. This has been replaced
with a new password algorithm. It should now work with Redhat, and
other Linux's based on GNU libc.
- The monitoring scripts have been updated
to support 64bit IRIX.
- The online help has been updated for
the replicataion module, and to fix an error in the tape restore example.
- The online tape catalog structures had
to be changed due to a bug in the backup group structure. This means
0.19 backup records are not compatable with 0.20.
Version 0.19
- This is the first release of the network
backup module. This module allows you to backup your UNIX machines
accross a network. It has many of the features of expensive backup
packages including:
-
The ability to backup accross a network.
-
The ability to backup many hosts at the same
time
-
Online indexes to simplify restores.
Most of the development work since the last
release has been to produce this module. a easy to use GUI is included
to make managing backups simple. It has been tested backing up 6
different hosts at a time, with IRIX, and Sun tape drives.
- All scripts now include version numbers.
This will allow you to customize them without fear of later upgrades wiping
them.
- Updates to aliases would fail running
newAliases. Fixed typo, so it works in this release.
- Bugs in the SGI disk monitoring scripts
have been fixed.
- The robustness of MATd has been greatly
increased.
Version 0.18
- Added Swap and Memory use monitoring to
MATd for Linux. The alarm threshold is (free - used).
- Created "hooks" into the GUI to allow
users to add there own modules to MAT. The file userdef1.tcl
contains an example and instructions of how to add new administrative functions
to MAT. Files libuser1.[ch] contain an example and instructions
for adding the administrative functions to the mat agent. Used in
conjunction with the GUI code it allows a user to add new administrative
functions to MAT.
- Wrote a parameter discovery script for
MATd. This was worth doing a new release for. When initially
installed MATd will attempt to automatically discover which parameters
it can monitor, and will build the configuration file accordingly.
Discovery is also added as a MATd task, so it can detect new hardware/services
and configure MATd to monitor them.
- Fixed bug in the Status screen.
Some queries would timeout. Just catching SIGCHLD is not reliable,
so had to augment with waitpid.
- Converted email alias tool to use the
general config library of functions. This is a necessary for allowing
multilple hosts to be updated from a single command.
- Changed MATd path so it is relative to
$MATHOME instead of bin/$MATHOME.
- Re-wrote WWW pages.
- Added MATd task status into MATd, and
the MAT agent. This is for later use so we can see the "health" of
a host just by looking at the MAT console. It will probably be incorporated
into the Probe function.
Version 0.17
- Show stopping bug fixed. Symbolic
links to the actual config files were not followed, as a result changes
were never made to real config files.
- Changed code so there is no migration
needed for: /etc/passwd, /etc/hosts, /etc/group, /etc/services
- Modify of users password fixed.
Old version put unencrypted copy in password file.
- Fixed lastlog display
Version 0.16
- Changed text display procedure so that on
communication problems such as timeouts and "host not found" it does not
popup a TK error box.
- Text display was affected by previous
colour scheme and bindings. Changed it so that most items will remove old
bindings first. For performance the larger lists (passwd, YP passwd)
do not wipe the bindings first. This should not be a problem, because
they should be replaced with new ones anyway.
- SunOS 4.1.x disk usage status fixed.
- Updated logs so they are more meaningful.
- NIS netgroup fails when entries cannot
be parsed. Changed it so these entries are now ignored.
- Password did not work with some special
characters notably "#".
- Error in install.agent script. Did not
create /etc/inetd.conf entry properly.
- Modify of some services entries failed.
Version 0.15
- Lastlog monitoring does not work (Don't
see the cause yet).
- The diskspace usage reports NFS filesystems
as well.
Version 0.14
- Mount GUI is not making the mount point,
and trying to mount the filesystem.
- Mount GUI only for Linux
- Documentation is not available on all
topics.
