Reboot the system.
# reboot
The number of supported pseudo terminals is now 176.
Modifying the maximum number of files a process can open
By default, each SUN OS process can open up to 64 files. If a Unix server is to be
connected with a number of terminals (usually more than 50), change the value to
400. To do so, edit file /etc/system to add the following line:
set rlim_fd_cur = 400
After modification, you must reboot the server to bring your configuration into
effect. You do not need to change other system kernel parameters.
Modifying System
Configuration File
inittab
Follow these steps to modify the system configuration file inittab:
1
Check whether a pseudo terminal has been configured in the inittab configuration
file.
Take the device ttyp50 as an example. Edit the file /etc/inittab and check whether
this file contains the following line:
T1:234:respawn:/etc/getty ttyp50
If the line is absent, add it. In the sample line, T1 is the identifier of the line. Each
line in the file inittab must have a unique identifier consisting of no more than two
characters. In system configuration file inittab, the third column of a line is
“respawn” for an active terminal and off for a dumb terminal.
2
Bring the configuration into effect after the addition.
# init q
Editing the ttyd
Configuration File
Refer to “Editing the ttyd Configuration File” on page 775 .
Modifying Route
Configuration File
The terminal access router is usually connected to the Unix server through WANs
and therefore located on an IP segment different from that of the Unix server, in
which case you must configure a route on the Unix server.
The following example shows how to do so:
# route add -net 10.110.96.0 63.1.1.250
