C-News in an NFS Up:
Control Messages Previous:
The checkgroups Message
sendsys, version, and senduuname
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''.
Again, you should never 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.
