I want to install ssh server running with HP-UX version v1.

I used below link for ssh download

https://h20392.www2.hp.com/portal/swdepot/displayProductInfo.do?productNumber=T1471AA

but when I install I am getting the below error in HP-UX 11i v1.

------------------------------------------------------------------------------

Could not obtain seed from PRNGd
ERROR:   could not generate RSA1 host key
ERROR:   The "configure" script for "Secure_Shell.SECURE_SHELL" failed
         (exit code "1"). The script location was
         "/var/tmp/BAAa25264/catalog/Secure_Shell/SECURE_SHELL/configure".

       * This script had errors and the execution of this fileset
         cannot proceed until the problem is fixed. Check the above
         output from the script for further details.

Do the device nodes /dev/random and /dev/urandom exist on your system?

The Release Notes of the HP-UX Secure Shell say that those device nodes are required. It also says that they are available by default on HP-UX 11iv1, 11iv2 and 11iv3 systems, but that's not quite true on 11iv1.

At least on older 11iv1 installations, you had to install the KRNG package separately to make the /dev/random and /dev/urandom device nodes available.

The KRNG package is available for free on software.hp.com:

Yes. The KRNG (Kernel Random Number Generator) will need a reboot of the server.

Is it possible to get lower version of ssh that do not require KRNG module ?

or is it possible to install openssh ?

Why would you not want to use strong random number generation? You'd only be helping to defeat the point of using ssh in the first place.

Doesn't want to reboot now?
