[HECnet] VMS question

I've way rusty on VMS, so I figured someone here can probably give me an answer way faster than I can figure it out myself. I brought SIGGE:: online two days ago. (VAX 7000-720). Started YCPIP services as well. Now the disk is full. I'm guessing some logging somewhere, as people are crazy about probing and poking. TELNET stopped working, but I can log in fine from DECnet or LAT. Can anyone tell me where logs go, and how to clean it up so I free some disk. Also, are there some known issue with the telnet server? If I telnet to the machine, it's just constantly spewing out one character. Probably 0xff.
