<DIV><SPAN class=884071221-13112007><FONT face=Arial color=#0000ff size=2>I've
had Projection errors when I havn't properly set up my epsg codes on the
server. ie.. I have a special version with epsg 42304 in it, and if I
havn't copied it over, it bails (because I refer to it in my map files).
Thus causing the subsequent errors. Does that help? I don't remember
the specific error I get - but it's along those lines.</FONT></SPAN></DIV>

<DIV><SPAN class=884071221-13112007><FONT face=Arial color=#0000ff size=2>To the
second part - I'd be interested in such a "debug-fest". I've been wanting
to get up to speed with version 5 and this would be a good way to get into the
nitty gritty changes.</FONT></SPAN></DIV>

<DIV><SPAN class=884071221-13112007><FONT face=Arial color=#0000ff size=2>That
said - i'm off for a couple of weeks, so if it was in December or later it would
be better for me - although not necessarily better for the
lab.</FONT></SPAN></DIV>

<P><SPAN lang=en-ca><FONT face=Arial size=2>============</FONT></SPAN> </P>
<P><SPAN lang=en-us><FONT face="Courier New" size=2>A plea for help, since
there are so many of you with relevant experience on this list. First,
some background, then a specific problem on a machine in the student lab,
followed by a general appeal for help to fix various little bugs here in the
Carleton labs.</FONT></SPAN></P>
<P><SPAN lang=en-us><FONT face="Courier New" size=2>We've been using Chameleon
for various assignments and labs at Carleton for at least a few years.
Initially DMSolutions sent in people (yay,</FONT></SPAN></P>
<P><SPAN lang=en-us><FONT face="Courier New" size=2>Jeff!) to set up and help
run the lab, and in the past couple of years I've managed to run them on my
own. We used a combination of student development on Windows and Linux
machines, and then publishing on a Mac Server box. It worked quite
well.</FONT></SPAN></P>
<P><SPAN lang=en-us><FONT face="Courier New" size=2>This year, the Windows
machines have had new security software installed which prompted me to suggest
that those students in my fourth year class which wanted to use
mapserv/chameleon in their projects do so under Linux, since we're also using
the OS for other work in the class (so they have familiarity in the
environment which many of the other students don't). </FONT></SPAN></P>
<P><SPAN lang=en-us><FONT face="Courier New" size=2>But I'm starting to kick
myself, because the linux in this lab was also updated last summer, and the
new distribution sets everything up with SELinux security. It took me a
couple of weeks, but I THINK I FINALLY have got rid of all the blocks that
created. But I'm also using newer chameleon code, and I'm getting php
errors which aren't obviously pointing at the problem, at least from my tired,
exasperated point of view - e.g.:</FONT></SPAN></P>

<P><SPAN lang=en-us><FONT face="Courier New" size=2>Does that mean anything to
any of you?</FONT></SPAN> </P>
<P><SPAN lang=en-us><FONT face="Courier New" size=2>Meanwhile, over on my main
web server, a series of upgrades to GDAL, PHP, etc, all combined to break the
pre-existing mapserv and chameleon projects from past years. I upgraded
mapserv itself to 5.0 and now mapserv-only projects are working, and the
chameleon apps are "partially" working - basic functionality is there but some
button images are not being found. </FONT></SPAN></P>
<P><SPAN lang=en-us><FONT face="Courier New" size=2>This has been a lower
priority for me, but should be fixed at some point. </FONT></SPAN><BR><SPAN
lang=en-us><FONT face="Courier New" size=2>In addition, if that had been
working properly, I would have had these students just do their projects on
the main server instead of the lab machines. I mention it here to see if
anyone feels up to helping me go through the errors and try to get that server
in shape - either interactively online, or maybe just an evening physically in
the lab?</FONT></SPAN></P>
<P><SPAN lang=en-us><FONT face="Courier New" size=2>Is there any interest in a
group "OSGEO web server implementation debug fest" / workshop ? :)
Getting these machines fixed up would also make it feasible to run web mapping
workshops in here in the new year, after all. </FONT></SPAN></P>
<P><SPAN lang=en-us><FONT face="Courier New" size=2>In addition, I know that
Cameron Wilson intends to run web mapping exercises in this lab next term in
an advanced cartography class, so lessons and repairs now will really help the
program overall.</FONT></SPAN></P>
<P><SPAN lang=en-us><FONT face="Courier New" size=2>I realize I've escalated
this from a small request to a giant appeal, but perhaps you guys have better
ideas than me about how to approach this.</FONT></SPAN></P>
