Jim would you like to share the repository information with Tod?
Otherwise, I'll verify that Mike's and ShadowM's repositories match.

Have you tried a clean rebuild after you make your changes?  Just on the
off hand chance something is not being recompiled correctly.

I would avoid exposing your server.  The account creation & validation code
is currently a little draconian.  If someone connects to your QLR server
using a client disk validated at your server will
overwrite their account data on their disk preventing them from being able
to connect to their original account on So until I get
the new user / validation code I've been working on tested, approved and
committed it is not a good idea to have multiple QLR servers running live
on "The Net".

As far as the VICE & Netcat issue goes, it seems to be prone to packet loss
that causes either undefined states in the Q-Link client that causes it to
hang (most notably during login) or undefined states that hang the RS-232
emulated device (common when it first establishes the initial TCP
connection).  In the case of the VICE/RS-232 issue, it often persists
between hard resets of VICE.  Perhaps my issue is that I'm using old
verions of VICE (whichever versions that are bundled with Debian Squeeze
and Ubuntu Lucid) and the use of the source port option -p.  I was always
led to believe the -p option was necessary in VICE.  Perhaps not.  The
moral of the story is VICE is a useful tool but I consider it a second
class citizen so to speak and I don't want to invest a lot of time trying
to resolve VICE issues in favor of real hardware.

I'll try to do some testing later tonight and get back to you.
