202 Command not implemented, superfluous at this site. I was thinking about 202 in particular when I suggested looking for all 2?? error codes.
The script only sends USER or PASS at this stage. I can't imagine many FTP servers wouldn't support them ;-) Perhaps it won't support PASS if a password isn't required after supplying the username, but if it doesn't support PASS it's a bit strange to have previously sent us a 331 requesting a password (and we only ever send PASS if the server returns a 331). The 200 code would probably make more sense in my opinion, in case a server only returns a 200 instead of 230 after a successful logon (still very odd behaviour though).
Let me say again that I'm very comfortable with accepting false positives in this case.
As previously mentioned, my current working version does support other 2xx codes, and will display any non-230 FTP server code as part of the output, making it easier to spot potential false positives. I just wanted to make sure that we're not introducing false positives when there could never be a false negative. It does sounds like it would be safer/best to initially support all 2xx codes and only modify the script if/as required. Thanks for the debate, hope you didn't mind me playing devil's advocate :) Rob _______________________________________________ Sent through the nmap-dev mailing list http://cgi.insecure.org/mailman/listinfo/nmap-dev Archived at http://seclists.org/nmap-dev/
