My Raq4 is having problems with the ftp/tcp. Here is the message that Iget; I have both restarted the ftp server ftp/tcp server failing (looping), service terminated.What is causing this and how is it corrected, saw several references butnot sure of fix.
I see this every once in a while when someone scans my server looking for anonymous ftp access. I believe it's a result of the h4x0r scanning software they use. It scans a block of IP's and connects/disconnects so fast that it freaks out proftpd or something. I usually look up their IP in ARIN and report the activity to the abuse contact.
HTH, j
