R2511-HP MSR Router Series Terminal Access Configuration Guide(V5)

7. Select [Advanced options].
8. Select [Pseudo ttys]. The default value is 32. Change the value to 256.
9. Compile the kernel.
# /etc/conf/bin/idbuild -B
10. Reboot the FEP.
# init 6
Now, the system can support up to 256 pseudo terminals.
You can also increase the number of pseudo terminals by installing the acp program and updating as
follows:
11. Change the value of kernel parameter NUMSCOPT to 256.
# /etc/conf/bin/idtune NUMSCOPT 256
12. Install the acp package, which is in the first disk for SCO UnixWare. Select a terminal number of
256 during installation.
# pkgadd -d cdrom1 acp
13. Install the update package, which is in the second disk for SCO UnixWare.
# pkgadd -d cdrom1 update711
After installation, the system rebuilds the kernel and reboots.
Modifying the maximum number of files a process can open
By default, each SCO UnixWare process can open up to 64 files. If a Unix server is to be connected to
a large number of terminals (usually more than 50), change the value to 400 with the following
commands:
# idtune SFNOLIM 400
# idbuild –B
Modifying the maximum number of processes a user can open
By default, each SCO UnixWare user can open up to 80 processes. If a Unix server is to be connected
with many terminals (usually more than 50), change the value to 500 with the following commands:
# idtune MAXUP 500
# idtune NPROC 1000
# idbuild –B
Modifying system configuration file ttydefs
Locate the line starting with "9600:" in file /etc/ttydefs. If the echoctl option is present, set it to –echoctl.
If Chinese cannot be used normally, add the –istrip option to the line. For example:
9600: 9600 sane imaxbel iexten -echoctl echoke -istrip -tabs ::: 4800
NOTE:
To run ttyd on the SCO UnixWare system, you do not need to configure pseudo terminal related
parameters in file /etc/inittab.
