Re: [suse-security] FTP: can connect but cannot transfer data

--> Maybe http://slacksite.com/other/ftp.html helps to understand the FTP protocol. When using passive ftp, you have to allow connections to all high-ports on the server. For active FTP, it's port 20 and 21 on the server but many ports on the client. Neither solution is really nice.

Yes I know. Most clients are behind firewalls, so both active and passive FTP doesn't work with the current settings.

Have you thought about using scp/sftp (there are nice clients for Linux and Windows) which is much easier for firewalling (you only need port 22).

Bingo! Never thought of that. Will try that immediately and report my finding here. Thanks (also Timo) for your help. Jeroen
