Hey, I'm currently running into difficulties on a multiuser system, (4.2-STABLE) we have 256 pty's (for some reason we still have pseudo-device pty 256, in the kernel conf...), and we are running out. Last year we ran into the same problem (February seems to be a busy month) and I believe that we followed the instructions in http://www.FreeBSD.org/cgi/getmsg.cgi?fetch=8198069+8200098+/usr/local/www/db/text/1999/freebsd-questions/19990607.freebsd-questions <quote> You can have more than 256 ptys; the problem is what to name them. You can easily get 384 ptys by extending the current scheme slightly (using /dev/tty[tuTU]*; /dev/ttyv* is syscons so we hit our limit with this naming scheme). Edit /dev/MAKEDEV and /usr/src/lib/libutil/pty.c </quote> However, I can't remember what we did (if we did at all) to MAKEDEV to overcome the 256 minor number limit. Can anyone help us out ? What is the possibility of creating more than 256 pty/tty devices ? If not, are there any plans to overcome this hard limit in the future ?
