Finally, there are three messages that may be used to find out about the
|
|
network's topology. These are sendsys, version, and
|
|
senduuname. They cause C-News to return to the sender the
|
|
sys file, a software version string, and the output of
|
|
uuname(1), respectively. C-News is very laconic about
|
|
version messages; it returns a simple, unadorned ``C''.
|
|
<P>
|
|
Again, you should <em>never</em> issue such a message, unless you have made
|
|
sure that it cannot leave a your (regional) network. Replies to
|
|
sendsys messages can quickly bring down a UUCP
|
|
network.<A HREF="footnode.html#9429"><IMG ALIGN=BOTTOM ALT="gif" SRC="foot_motif.gif"></A>
