syslog.

First, you add the devtools repository:
http://wiki.maemo.org/Documentation/devtools/maemo5
Then you install rootsh and syslog from that repository. Reboot, try connecting.
Then, open up the X Terminal, and use this to gain root permissions
Things will be logged to /var/log/syslog
To print out messages relating to EAP:
That might miss things that are important, though. Viewing the full log from the terminal is inconvenient, so copy it into your documents folder as syslog.txt: (Keep in mind this is Linux so it's case sensitive)
And then you can look at it through the file manager, or hook it to your computer and copy it off.


And yeah, I could never get this set up on my E51. "Error: There was an error" style messages do not make things easy. I love these error messages- I'm just disappointed that maemosec appears to be closed source (I don't quite have everything figured out here so I'm not sure) so I can't figure out how to fix it myself.
