No more sudo package for 11.23?

Hi,

I need to install sudo in some of our corporate HP-UX servers, since this package is currently not installed in the server(s).
However, from this site : HP-UX Porting and Archive Centre | Home, this package is no longer available for HP-UX v 11.23. It only has the depot package for HP-UX 11.31.

Does this mean I no longer can install sudoers package for HP-UX v 11.23?

How can I install this package for this version of HP-UX?

Thanks,

(11.23) 11i v2 was released in 2003, and was EOL'd in December 2015

11i v3 will be supported up to 2020.

In this case, then how do I provide "sudo" privileges for some commands that user have requested for?

There is still a gcc for HP-UX 11.23.
Then you can download the sources and compile.
But sudo might require several GNU libraries to also be compiled (and even compile-helpers like GNU make).
