You need to re-compile the kernel with more pseduo terminals (pty's).
If you have made the kernel already DON'T copy the GENERIC over
the configure file for it.
1. Make sure you have kernel source installed, if not install it.
2. cd /usr/src/sys/i386/conf
3. cp GENERIC name_for_your_kernel
4. vi name_for_your_kernel (assuming it's the editor you
use vi)
Goto end of file, find pseudo-device
pty line, increase # to # of people
you would like logged in. Save
file. I believe screen
may also use pty's so it's not
stricly the maximum # of people
that can be logged in. I think you
can goto 64 w/o any major changes
anywhere else. I use 32 personally
and have between 3 and 16 users on
most of time.
5. config name_for_your_kernel
6. cd ../../compile/name_for_your_kernel
7. make depend && make
8. cp kernel /
9. reboot your machine and the extra pty's will be available
assuming the compilation process went ok. You may need
to use the MAKEDEV script to generate more pty devices
in the etc directory. (you can cd /dev;ls pt* and see how
many devices are there already).
