Obtaining client IP address
Craig Macbride
into a TLS, TLS059) to obtain the IP address of a client connected to a
SCO box.
Now, "who" has some extra options which can provide this information,
but somewhat unreliably. "who -mx" returns the client host name, but
truncates it to 16 characters, which, unless your domain name is _very_
short, means that part of the domain portion will not be printed.
"who -mux" allows a few more characters at least, but is not documented
as doing so. Indeed, the fact that "who -x" truncates the host name is
not documented in the first place, so it's hardly a behaviour I'd like
to depend on.
Is there a version of nwho or a reliable equivalent around for 5.0.x?

"finger -lp" shows the complete hostname, albeit in a very verbose style
of output.

After a bit of ftp-searching, I came up with a good one for you. And for
us, thanks!
Download ftp.armory.com/pub/scripts/oa/oanwho (script)
Download ftp.armory.com./pub/scobins/flon (binary for 5.0.x)
chmod 755 flon, mv to a bin directory in your path.
Edit oanwho (for 5.0.4):
Change line 1 to: #!/usr/lib/scosh/utilbin/oash
Change line 10 to: OALIB=${OALIB-"/usr/lib/scosh"}
chmod 755 oanwho and mv to a bin directory in your path.
Do 'oanwho'. It'll give you the FQDN of logged-in users. not their IP
numbers. Presuming you have DNS running on your machine.
Thank John H. Dubois iii!

'man utmpx' shows 256 characters available for storing the host
name. I think you can safely assume that who -mux will return
up to 256 bytes of host name. I, personally, trust and use it.

It needs a slight modification (. after the $6) if the names are
not bare hostnames in your local domain.
/etc/host `who -mux | awk '{print$6"."}'` | head -1 | awk '{print$4}'
