[Mono-aspnet-list] Mod_mono and apache issue.

When you run xsp2 it will run as your login. Apache, however, is a
daemon (like a service in Windows) and it'll run as a different account.
Apache (via mod_mono) launches an app called mod-mono-server2 which
hosts your application. This will need to read your aspx files and dlls
in order to do so.
You can see those processes by running the following commands:

ps -ef | grep apache
on my machine I see:
www-data  4409 22479  0 Aug16 ?        00:00:00 /usr/sbin/apache2 -k
start
root     22479     1  0 Aug15 ?        00:00:17 /usr/sbin/apache2 -k
start
www-data 31551 22479  0 Aug16 ?        00:00:00 /usr/sbin/apache2 -k
start
www-data 31552 22479  0 Aug16 ?        00:00:00 /usr/sbin/apache2 -k
start
www-data 31553 22479  0 Aug16 ?        00:00:00 /usr/sbin/apache2 -k
start
www-data 31554 22479  0 Aug16 ?        00:00:00 /usr/sbin/apache2 -k
start
www-data 31555 22479  0 Aug16 ?        00:00:00 /usr/sbin/apache2 -k
start

the first column shows the user(login) that the process is running as.

ps -ef | grep mono
on my machine I see:
www-data 31550     1  0 Aug16 ?        00:00:06 /usr/bin/mono
/usr/lib/mono/2.0/mod-mono-server2.exe --filename
/tmp/mod_mono_server_default --applications
/TaskListWS:/home/garyt/software/TaskList,/TaskListRESTService:/home/gar
yt/software/TaskListRESTService --nonstop

So, the account www-data will need read access to your application files
and if it doesn't it'll fail.

@gary: I didn't get you there. What did u mean by  "user that
mod-mono-server2 is
running as has access to your application files"?

@mark: I did try out that tool earlier, and that still didnt help.
