Well I have to carry out that thread... I just migrated from vsftpd to proftpd.
Unfortunately ftps does not work, as I got the message "auth not undestood" for "auth tls" and "auth ssl", as some others mentioned on page 2 of this thread.
But what I am wondering is, if the debian etch package is carried out with mod_tls.c or not as proftd -l does not indicate this module to be builtin.
But even omitting the "ifmodule" in the config does not help or throw an error either. Also the tls.log is not beeing created. proftpd -t indicates mod_tls to be loaded....
Does anyone still has the same problem with proftpd using debian etch?
