CRPTY(8)                        Domain/OS BSD                         CRPTY(8)



NAME
     crpty - create pseudo tty device entries

SYNOPSIS
     /etc/crpty count [directory]

DESCRIPTION
     crpty creates the pairs of device entries that are used by the pseudo-
     terminal driver; see pty(4).  The number of psuedo-terminal device pairs
     created controls the number of simultaneous incoming rlogin and telnet
     processes to an individual node.

     crpty takes the argument count, which is the number of pairs of pty
     entries to create.  We recommend a maximum of 16 pairs on all machines
     other than the DN10000 Series.  For the DN10000 Series, we recommend up
     to the maximum number of pairs allowed, which is 64.

     crpty names the device pairs ptyp[0-f] and ttyp[0-f] for the first
     sixteen device pairs.  Subsequent sets of sixteen device pairs are named
     ptyq[0-f] and ttyq[0-f], ptyr[0-f] and ttyr[0-f], and ptys[0-f] and
     ttys[0-f], respectively.

     The optional argument directory allows you to specify the directory in
     which the device entry pairs are created; by default, the entries are
     created in /dev.

     You must be logged in as root to run crpty.

EXAMPLE
     /etc/crpty 2

     creates /dev/ptyp0, /dev/ttyp0, and /dev/ptyp1, /dev/ttyp1.
