>Environment:
System: NetBSD horn.ics.muni.cz 1.3E NetBSD 1.3E (HORN_13) #0: Mon Mar 16 11:06:02 MET 1998 salvet@minea.ics.muni.cz:/home/salvet/src/sys/arch/i386/compile/HORN_13 i386


>Description:
	telnetd tries to open /dev/ptyv0, if it does not exist
        (on i386 with pcvt), it skips other possible ptys

>How-To-Repeat:
        Let 97 users log in simultaneously :-)

>Fix:
        Change src/libexec/telnetd/sys_term.c to use openpty()
        or exclude "v" from pty names.
