Thanks for the reply and help Robin and i like the way you've analyzed my question, which gave me good understanding. sorry, i should have give more details.

My question was
How can we make "telnet sessions" secure ? or would like to have secure telnet sessions like SSH. (encrypted/secure)


Thanks for the reply and your help Bakunin and please see the below links related to other OS. yeah, as you mentioned we usually use SCP,SFTP and SSH for regular day-to-day work.
but would like to know about securing telnet sessions using SSL or any other security mechanism.

I found something on google, not able to post URLs here. could you please google "Configuration details for securing Telnet with SSL" & "Telnet server and Secure Sockets Layer (SSL)".

Please see the very first IBM links for each search.

appreciate your time.

nstrtel

nstrtel(5)							File Formats Manual							nstrtel(5)

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 parameter 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 values.  For information about the effects of installation on tun-
       able values, consult the documentation for the kernel software being installed.	For information about optional kernel  software  that  was
       factory installed on your system, see at
