Thanks for the tip there but I cant find any function called pty_create_slave in the source. N.B. Machine is running 5.4 but I also looked on 6.2 which we could upgrade to but still couldn't find it, so I assume you may be talking about something that's in current which we couldn't risk on this machine. Is this something that's possible on 5.x / 6.2 or something that will need a lot of work? Regards Steve ----- Original Message ----- From: "Dag-Erling Smørgrav" <des@des.no> You need to change the way ptys are named in pty_create_slave() and pty_clone() in sys/kern/tty_pty.c. Just changing names won't help as the sequence is also hardcoded in pty_clone(). You also need to change grantpt(), openpty() and any other userland code which has hardcoded knowledge of the naming scheme: des@ds4 ~% gfs pqrsPQRS src/sys/kern/tty_pty.c: static char *names = "pqrsPQRS"; src/sys/kern/tty_pty.c: * pts == /dev/tty[pqrsPQRS][0123456789abcdefghijklmnopqrstuv] src/sys/kern/tty_pty.c: * ptc == /dev/pty[pqrsPQRS][0123456789abcdefghijklmnopqrstuv] src/contrib/telnet/telnetd/sys_term.c: for (cp = "pqrsPQRS"; *cp; cp++) { src/usr.sbin/ac/ac.c: strchr("pqrsPQRS", usr.ut_line[3]) != 0 || src/lib/libutil/pty.c: for (cp1 = "pqrsPQRS"; *cp1; cp1++) { src/lib/libc/stdlib/grantpt.c: #define PT_DEV1 "pqrsPQRS" Alternatively, set kern.pts.enable to 1, and find and fix the hang-on-close bug in the pts code (if it hasn't been fixed already) DES -- Dag-Erling Smørgrav - des@des.no ================================================ This e.mail is private and confidential between Multiplay (UK) Ltd. and the person or entity to whom it is addressed.
