Next: C-News in an NFS Up: Control Messages Previous: The checkgroups Message
sendsys, version, and senduunameFinally, 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.
