Re: [Proftpd-user] mod_proxy

thank you all for taking time to reply to my stupid question.

i must realize that my goal about proying ftp by domain is a no exit way.

i realized that most of users, running old systems like as400, can't simply enter a domain name in here ftp adress field.

so, an additionnal floating ip by domain do the work and allow to redirect surely to the linked domain container to 'standard' proftpd server.

thanks again.

The FTP protocol does not have a native way to tell to the server the
domain that was used when connecting - unlike HTTP, which has the Host
header. With plain FTP it would be impossible to do this.

Actually, the FTP protocol now supports a HOST command; see RFC 7151:
https://datatracker.ietf.org/doc/html/rfc7151

and ProFTPD (and mod_proxy) support/honor the HOST command. But this assumes that the client in question uses the HOST command.

Cheers,
TJ
