[HTCondor-users] condor_who spits out garbage message

[Bert DeKnuydt <Bert.DeKnuydt@xxxxxxxxxxxxxxxx>]

Dear Condorants,

Here each invocation of 'condor_who' of version 9.0.2 spits out
the message:

 ~ Â condor_who
(Not all processes could be identified, non-owned process info
 will not be shown, you would have to be root to see it all.)

This on CentOS 8 and Fedora (anything).  The reason is
that condor_who now exec's

>  netstat  -n -t -p -w

The '-p' option, causes this line to be printed to stderr,
unless invoked as root.

Obviously, this extra lines are annoying, cause users to file
bug reports and make scripting a pain...

Workaround:  replace condor_who with a one-liner script that
exec's condor_who, but closes stderr (condor_who 2>&-), or
alternatively, make a file /usr/local/bin/netstat which
exec's netstat, but closes stderr.  Not ideal though.

But, is the use of netstat actually a good idea ...  Even on CentOS 7, 
of
stone age time, the first lines of man netstat read:

    This program is mostly obsolete.  Replacement for netstat is ss.

(No idea of Ubuntu/Debian though)

Greetings, Bert.

FYI: On Centos 7 the error message is different.
