Accomplishments past period:
ONGOING: Testing and bug fixing of current Athena release.
Last Month's goals:
DELAYED: Finish Solaris 10 installer integration for summer's Athena
full release.(Still awaiting server upgrade.)
DELAYED: Look into using the GNU Mailutils as an IMAP and Kerberos 5
compliant drop-in replacement for mh.
DONE: Write white paper that presents results of our evaluation of
SLED 10 as the basis for the next major Athena release.
Community Milestones Met:
Patch release containing updated Java development kit, Firefox
1.5.0.9, fixes for Linux tcpdump, OpenSSH, Evolution, jwgc, changes
relating to olc migration to RT, and backed out OpenAFS 1.4.2 on
Linux side.
Other Accomplishments:
* Published White Paper on future of Athena.
* Worked with Red Hat on the "clock runs backwards" problem.
* Integrated Solaris security patch for next patch release.
* Upgraded ispell for next patch release at user request.
* Crafted patch to reactivate to make sure it will not run before
Solaris has completed system startup.
* Customer visit to fix an install problem.
* Prepared for moving build machines from W92 machine room to co-lo
facility.
Next month's goals:
ONGOING: Testing and bug fixing of current Athena release.
OLD: Finish Solaris 10 installer integration for summer's Athena full
release.(Still awaiting server upgrade.)
OLD: Look into using the GNU Mailutils as an IMAP and Kerberos 5
compliant drop-in replacement for mh.
OLD: Write white paper that presents results of our evaluation of
SLED 10 as the basis for the next major Athena release.
Next Community Milestone(s):
Patch release containing Firefox 1.5.0.10 and its printing fixes,
Solaris security patch, flash plug-in upgrade for linux. (May deploy
patch release in March rather than February.)
Issues:
The latest Red Hat kernel introduces a clock skew problem that
renders it unusable on some of our supported hardware. We need this
issue resolved before we can use their latest kernel release. If
absolutely necessary, we could craft a local fix for this problem,
but we would like to avoid this if possible. Update 2/6/07: We are
working with a senior tech at Red Hat to understand this problem.
Kerberos 4 mail clients like mh, xmh, and exmh are going to die when
Kerberos 4 is shut down. Our plan is to investigate the Gnu
Mailutils as a way to offer the same functionality with Kerberos 5.
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 08/06 09/06 10/06 11/06 12/06 01/07 Delta
LINUX 845 799 788 788 773 813 +40
SUN 427 347 343 338 341 329 -12
Count of systems registered for RHN (Non Athena update):

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: 08/06 09/06 10/06 11/06 12/06 01/07
Total: 172272 272239 260454 237837 198853 177729
Unique: 9564 11202 10783 10383 10016 9270
Median: 4 10 9 8 7 5
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: Ending February 3, 2007
177729 ( other 96591 quickstation 23729 dialup 30543 cluster 26866 )
Unique logins for four week period:
9270 ( other 5133 quickstation 5334 dialup 2709 cluster 4126 )
Median logins for four week period:
5 ( other 4 quickstation 2 dialup 3 cluster 3 )
