| 1) Is there a limit, either with device files or the kernel, on the number
|    of remote logins permitted across ethernet ?  We are thinking of using
|    TCP/IP terminal servers instead of RS232 cabling.  If so is there a work
|    around ? (this would have to be something like just making more device
|    files as we will not have a source license) We will be using vt100's,
|    pc's, etc (NOT X-terminals).

>From a quick glance at the 4.0 source, you're limited to ~64 remote users.
The telnet and rlogin daemons only look for 64 ptys.  That's a piece of
bad code inherited, I believe, from Berkeley -- the right way to have done
it would be to have a subroutine that did all that, so you could fix it in
one place.  But that would have been too simple...
