How do I add pseudoterminals to the system? If you have lots of telnet, ssh, X, or screen users, you will probably run out of pseudoterminals. Here is how to add more: 1. Build and install a new kernel with the line pseudo-device pty 256 in the configuration file. 2. Run the commands # cd /dev # sh MAKEDEV pty{1,2,3,4,5,6,7} to make 256 device nodes for the new terminals. 3. Edit /etc/ttys and add lines for each of the 256 terminals. They should match the form of the existing entries, i.e. they look like ttyqc none network The order of the letter designations is tty[pqrsPQRS][0-9a-v], using a regular expression. 4. Reboot the system with the new kernel and you are ready to go. Dave
