Max Telnet Sessions parameter in 11.x kernel

[Ray Evans]

In the 11.x kernel, telnetd looks to ntrstl(?) parameter to determine max allowed connections.

What controls this in the 10.x environment?

nstrpty

::0:Streams:0:Max Number of Streams-Based PTYs

Set the system-wide maximum number of streams-based PTYs that are
allowed on the system.
Acceptable Values:

Minimum: 0
Maximum: Memory limited
Default: 0

Specify integer value. For more information, see Specifying Parameter
Values.
Description
This parameter limits the number of streams-based PTYs that are allowed
system-wide. When sending data to PTY devices (such as windows), a PTY
device must exist for every window that is open at any given time.

This parameter should be set to a value that is equal to or greater
than the number of PTY devices on the system that will be using
streams-based I/O pipes. Using a parameter value significantly larger
than the number of PTYs is not recommended. nstrpty is used when
creating data structures in the kernel to support those streams-based
PTYs, and an excessively large value wastes kernel memory space.

For more information about streams and streams programming, refer to
the STREAMS/UX for the HP 9000 Reference Manual.
