Problems with conserver after OS upgrade

  Apologies for those who feel this is an OS problem, and you're  
likely right.  That, and/or a "stupid user trick".

  I was running NetBSD 4.0_STABLE for more than a year, with  
conserver 8.1.16 built from pkgsrc.  This worked fine.  I'd written a  
perl program to auto-login over a [telnet] connection to port 2000+ on  
my cisco access server.  (I tried ssh at some point, but it appears I  
wasn't using that.  Maybe I never got it to work?)

  Anyway, I recently upgraded the base OS on the console server, and  
built a new version of conserver, still 8.1.16.  Now, I seem to have  
no working consoles.

  If I run "console -x", I simply get no output.  If I try to console  
to a console, I get a brief pause followed by:

console: forwarding level too deep!

  Interestingly, I'm also seeing the following in the log:

[Thu Jun  4 22:46:46 2009] conserver (1139): ERROR: FileRead(): SSL  
error on fd

  Any idea what's gone wrong?  The console and conserver binaries  
should be built with the same version of openssl as are on the machine  
at the moment.  Any other ideas as to what might be causing this issue?

  Thanks...
