Accomplishments past period:
ONGOING: Testing and bug fixing of current Athena release.
Last Month's goals:
DELAYED: Create new Linux installer based on a more current RHEL 4
Kernel that includes necessary drivers for Dell Optiplex 755.
PROGRESS: Adapt Debathena materials and procedures for Athena 10 project.
DONE: Set up IPS build server for Athena 10.
PROGRESS: Set up apt repository for testing Athena 10 packages.
DELAYED: Develop Athena10 solution for time synchronization against
time.mit.edu (assigned to amb.)
PROGRESS: Develop Athena10 solution for emacs site configuration (assigned to
amb.)
PROGRESS: Develop Athena10 solution for Firefox local configuration (assigned
to rbasch.)
DELAYED: Rebuild and bring online the W92 test cluster.
DELAYED: Develop Athena10 solutions for other items in project plan as
resources are available.
Community Milestones Met:
Other Accomplishments:
* diagnosed kernel memory corruption bug affecting Debathena build
infrastructure and determined appropriate work-around.
* Demonstrated that Athena 9.4 works as a VMware guest under RHEL 5
x86_64 host, using amb's beta install CD under bridged networking.
Next month's goals:
ONGOING: Testing and bug fixing of current Athena release.
OLD: Create new Linux installer based on a more current RHEL 4
Kernel that includes necessary drivers for Dell Optiplex 755.
OLD: Adapt Debathena materials and procedures for Athena 10 project.
OLD: Set up apt repository for testing Athena 10 packages.
OLD: Develop Athena10 solution for time synchronization against
time.mit.edu (assigned to amb.)

OLD: Rebuild and bring online the W92 test cluster.
OLD: Develop Athena10 solutions for other items in project plan as
resources are available.
NEW: Deploy work-around for memory corruption issue on IPS Athena build
server.
NEW: Decide what we want to do about possible Athena VMware image
offering.
Next Community Milestone(s):
Patch release when necessary.
Issues:
NEW: Lack of support for Kerberos 5 on the MIT PO servers is holding up
development of a solution for nmh, and may create extra work for
integrating Evolution and alpine into Athena 10.
NEW: It is increasingly difficult to integrate MIT's custom LPRng
printing solution into modern client desktops. In concert with Server
Operations we are investigating changes which would allow us to use
native printing software, possibly at the expense of completely
de-supporting client-side authenticated printing.
NEW: Test Cluster dis-assembled as part of the redo of office space.
This is impacting roll-out of the new Athena installer, and will impact
our ability to respond to issues requiring testing.
Ops has some concerns about a desktop-server platform split (Ubuntu
vs. RHEL 4). We need to keep in communication with them about that.
Kerberos 4 mail clients like mh, xmh, and exmh are going to die when
Kerberos 4 is shut down. Our plan is to investigate amending inc to
support Kerberos 5 as soon as the mail servers get Kerberos 5 support.
Key learnings:
Additional comments:
Athena Monthly machine counts:
Method: On install, machines get a unique ID. Each day every system
reports its existence to a central syslog. This method over-counts
systems installed multiple times. Systems running Athena than 9.0 or
earlier are not counted.
Summary: Here we see the effect of cluster renewal beginning to
replace Suns with Linux systems.
SYSTYPE 09/07 10/07 11/07 12/07 01/08 02/08 Delta
LINUX 849 856 820 799 851 834 -17
SUN 278 270 259 255 256 233 -23
Count of systems registered for RHN (Non Athena update):
This month we swept through the registrations and eliminated a bunch
of redundant entries.

Monthly Athena Login counts:
Method: By reviewing of the logs of the service that makes
personalized notifications to users at login time, we are able to count
the number of unique Athena logins. Here we display the total number of
logins over a four week period, the number of logins by unique user ID
and the median number of logins per unique user ID.
Date: 09/07 10/07 11/07 12/07 01/08 02/08
Total: 254619 231773 213877 175480 146417 217997
Unique: 10981 10411 10158 9653 8861 10013
Median: 9 9 6 7 4 9
Breakdown for current month:
(Total of unique logins will be less than the sum of the sources,
since each source login only gets counted once.)
Total logins for four week period Sat, 1 Mar 2008 07:00:00:
217997 ( other 123432 quickstation 37425 cluster 57140 )
Unique logins for four week period:
10013 ( other 6824 quickstation 6243 cluster 5644 )
Median logins for four week period:
9 ( other 4 quickstation 3 cluster 6 )
