[comp.sys.sgi] What does the "

jba@harald.ruc.dk (Jan B. Andersen) (08/02/89)

When I logon (using telnet) to a SUN running SunOS it normally
displays something like:

  SunOS UNIX (hostname)

I'm setting up an IRIS-4D workstation named yrsa (defined in /etc/sys_id)
which shows

  4D1-3.147 IP6 yrsa ((null))

instead. What does this "(null)" mean and how do I change it?
I'm not running YP if that is of any importance.

I have looked in all the manuals, but without success.

There was a bug introduced in telnetd some time ago, and fixed not long
afterwards which caused this symptom.  It was an error in translating stuff
to use uname(2)--an extra %s in an sprintf(3) pattern.  The problem does
not seem evident in 3.1G.  Even better, 3.1G identifies itself as "4D1-3.1G."
