You can increase the maximum amount of PTYs by editing a lot of source files on your system. There is some good news: in -CURRENT we switched to Unix98-style PTYs (/dev/pts/%u). Right now the maximum amount of PTYs is limited to 1000 (0 to 999). We're currently limited to 7 characters (pts/999) because our utmp/ wtmp/lastlog files only reserve 8 bytes for the TTY name. If you're brave enough, you can increase UT_LINESIZE in include/utmp.h and MAXPTSDEVS in sys/kern/tty_pts.c. Be sure to recompile everything and to remove your utmp/wtmp/lastlog files. -- Ed Schouten <e...@80386.nl> WWW: http://80386.nl/ _______________________________________________ freebsd-hackers@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-hackers To unsubscribe, send any mail to "freebsd-hackers-unsubscr...@freebsd.org"
