NAME
       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.

WARNINGS
       All HP-UX kernel tunable parameters are release specific.  This parame‐
       ter  may	 be  removed or have its meaning changed in future releases of
       HP-UX.

       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  val‐
       ues.  For information about the effects of installation on tunable val‐
       ues, consult the documentation for the kernel software being installed.
       For  information	 about	optional  kernel  software  that  was  factory
       installed on your system, see at
