Antw: [suse-security] Problems Understanding SuSEfirewall2

19 May 2003

      Hello,

as I recognize so far you use active ftp (port 20, ftp-data). IMHO it is a quite large security hole. We only allow passive ftp connections. Try http://slacksite.com/other/ftp.html for some explanation.

Greetings
Olaf
