>Release: <NetBSD-current source date> NetBSD 1.5
System: NetBSD fartmangler.redback.com 1.5.1_ALPHA NetBSD 1.5.1_ALPHA (NETZUUL) #34: Mon Apr 16 19:22:08 PDT 2001 firstname.lastname@example.org:/amd/netapp6/netbsd15/nbsrc/sys/arch/i386/compile/NETZUUL i386
According to the i386 MAKEDEV, pty6 (aka ptyv*) conflicts with the
console ttyv0 device, so it's not created.
However, openpty() (basesrc/lib/libutil/pty.c) has
#define TTY_LETTERS "pqrstuvwxyzPQRST"
and so it tries to allocate/use ptyv, which fails horribly.
This bug is not only in 1.5, but is in -current as well.
Try to create more than 80 telnet/sshd sessions on a box.
If ttyv* is no longer being used, fix MAKEDEV to create the devices and
not worry about it.
If ttyv* is still being used, whack 'v' from the TTY_LETTERS string.
Of course, having some brave soul write a sysV-ish /dev/pts/37-style
thing wouldn't be bad...
