if the result is less than 1 second. The script should say as port open

nstrtel - specifies the number of telnet device files the kernel can support for incoming telnet sessions
VALUES
Failsafe
Default
Allowed values
(Subject to available physical memory.)
It is best to use the default value, and there should not be any need to lower it. However, if the simultaneous telnet connection load is
very high, then the value of could be increased.
Recommended values
(Default value.)
DESCRIPTION
The telnet daemon uses two STREAMS-based pseudo-terminal drivers and The kernel parameter, can be used to tune the number of pseudo-termi-
nals. specifies the number of kernel data structures that are created at system boot time that are required to support the device files
used by incoming telnet sessions on a server. If the command or SAM is used to create more telnet device files, the value of must be
increased accordingly or the device files cannot be used because there are no kernel data structures available for communicating with the
system.
Who Is Expected to Change This Tunable?
Anyone.
Restrictions on Changing
Changes to this tunable take effect at the next reboot.
When Should the Value of This Tunable Be Raised?
When there is an increase in the load of telnet connections and there are no device files available to open telnet connections, then this
kernel parameter should be increased.
When the error is encountered, then the device files have been exhausted and should be raised. Once the value of is raised, should be run
to create new device files. (If SAM is used to raise the value of is run automatically.)
What Are the Side Effects of Raising the Value of This Tunable?
More resources would be consumed. Extra kernel data structures, and extra device files may clog the system.
When Should the Value of This Tunable Be Lowered?
It is not advisable to lower the tunable value from the default value. Consult HP Support before lowering this tunable from the default
value.
What Are the Side Effects of Lowering the Value of This Tunable?
Though not recommended, there would not be any side effects.
What Other Tunables Should Be Changed at the Same Time?
None.

Installation of optional kernel software, from HP or other vendors, may cause changes to tunable parameter values. After installation,
some tunable parameters may no longer be at the default or recommended values. For information about the effects of installation on tun-
