Solaris Tunable Parameters Reference Manual

Pseudo Terminals

pt_cnt (Solaris 7 and Earlier Releases)

Description

Number of /dev/pts (the pseudo terminal devices used by telnet or rlogin for network logins) entries to create on a reconfiguration boot. This parameter effectively limits the number of users that can simultaneously be logged in across the net to the value of pt_cnt. You must do a reconfiguration boot (boot -r) after making the change to the /etc/system file for the additional device nodes to be created.
