Hi, playing around with netcat, I tried out the example fom its README, the command 'echo QUIT | nc -v -w 5 target 20-250 500-600 5990-7000', which should "inform you about a target's various well-known TCP servers", and I took as my 'target' 'localhost' (completely stand-alone PC).
Surprisingly there showed up among other things even an ftp-server (output: "wabe.in-bonn.de [127.0.0.1] 21 (ftp) open 220 wabe.in-bonn.de FTP server (Version 6.2/OpenBSD/Linux-0.10) ready.") It's surpring because I never installed any ftp-server on my system. The only servers I installed internally are boa (webserver) and leafnode (news). Can anybody explain this message? I would be interested to know how to disable this ftp-server -- I only have a dialup ppp-connection to the net five-six times a week. The other strange thing was an unknown service on port 6000: "wabe.in-bonn.de [127.0.0.1] 6000 (?) open" What does this one mean?
