Help, I followed this Tutorial HERE to install FROFTPD 14 Proftpd In order to install Proftpd, run apt-get install proftpd ucf You will be asked a question: Run proftpd from inetd or standalone? <-- standalone Then open /etc/proftpd/proftpd.conf and change UseIPv6 from on to off; otherwise you'll get a warning like this when you start Proftpd: - IPv6 getaddrinfo 'server1.example.com' error: Name or service not known vi /etc/proftpd/proftpd.conf [...] UseIPv6 off [...] For security reasons you can also add the following lines to /etc/proftpd/proftpd.conf (thanks to Reinaldo Carvalho; more information can be found here: http://proftpd.org/localsite/Userguide/linked/userguide.html): vi /etc/proftpd/proftpd.conf [...] DefaultRoot ~ IdentLookups off ServerIdent on "FTP Server ready." [...] ISPConfig expects the configuration to be in /etc/proftpd.conf instead of /etc/proftpd/proftpd.conf, therefore we create a symlink (you can skip this command if you don't want to install ISPConfig): ln -s /etc/proftpd/proftpd.conf /etc/proftpd.conf Then restart Proftpd: /etc/init.d/proftpd restart When I restart I get this Error: Starting ftp server: proftpd - Fatal: unknown configuration directive '[...]' on line 10 of '/etc/proftpd/proftpd.conf' failed! When I look at line 10 I get the same thing that is describd on the tutorial: [...] UseIPv6 off [...] Is there someone who knows this problem? Help please
