Configuration prerequisites

Adding VTYs

If there are not enough pseudo terminals on the HP-UX server, you can add new pseudo terminals by

modifying the system file as follows:

1. Launch sam.

# sam

2. Select [Kernel Configuration].

3. Select [Configurable Parameters].

Change the value of the npty parameter to 256.

4. Compile the kernel.

5. Reboot the device.

Now, the number of pseudo terminals is 256 in the directories /dev/pty and /dev/ptym.

Link the added devices to /dev as follows:

# ln /dev/pty/ttyy0 /dev/ttyy0
