hi,
following the implementation of the Solaris login server (willow), we are planning to move the web server, wolfsbane, to this platform. compared to the previous change on the web server (from Apache to ZWS), we don't expect this to require as much effort from users. for example, there is no need to change your htaccess or rewrite rules, because we will be using the same web server software.
for most tools (e.g. simple CGI or PHP scripts), there will be no need to change anything. in order of likelihood, the most common problems will be:
* missing modules (for PHP/Perl/Python) * missing libraries (for C/C++) * different versions (e.g. PHP 5.3 vs 5.2, Python 2.6 vs 2.5) * OS differences
if you find missing modules or libraries, please file a request on JIRA to have these installed. for version differences, normally no changes will be required; if any are required, they will be documented in the release notes for the language in question, and should be easy to do. in extreme cases (where converting to the new version would be very difficult), we may be able to install old versions of the affected software.
there are unlikely to be many people affected by OS differences; this would only happen if your tool calls external programs, which is uncommon. if you encounter a problem of this sort and can't solve it yourself, you can ask for help on IRC or the mailing list. there are some notes about Linux->Solaris migration on the TS wiki at https://wiki.toolserver.org/view/Using_Solaris.
there will be a one month test / migration period, during which you can test the web server on willow. to do this, replace "toolserver.org" in your tool's URL with "willow.toolserver.org", for example:
http://willow.toolserver.org/~jsmith/mytool.php
this will last until Wednesday, 19 August, at which point wolfsbane will be converted.

this will last until Wednesday, 19 August, at which point wolfsbane will be converted.
we will be proceeding with this as planned on Wednesday. to avoid downtime, the web server will move to willow during the reinstall (which should take around an hour), then move back to wolfsbane. the OS install on wolfsbane will be identical to willow, so if you have already tested your tools, you should have no problems.
crontabs from wolfsbane will be backed up, but _not_ reinstalled after the maintenance. instead, they will be saved as "crontab.wolfsbane" in your home directory. you should check your crontab for any changes needed, then reinstall it:
% crontab $HOME/crontab.wolfsbane

this maintenance was completed successfully. as usual, in case of problems, missing software, etc., please file a request in the TS project in JIRA.
