For the last week or so every day for about 6 to 10 hours someone is logging in and out continuously to our anonymous ftp. They don't stay logged in. It seems like it must be an automatic process aimed at tying up our anonymous ftp. The ID of the server doing this is can59-4-82-240-1.
As a result our wtmp file grows very large very quickly and disk space runs out. Does anyone else have this experience? How can we stop this happening?
