Enable the FTP (vsftpd) service in Linux

For other users, their home directories on the server are displayed as root directories. /Etc/shells checks whether a valid user shell exists by default before allowing local users to log on. In case of PAM Authentication unavailability. /Etc/ftpusers this file contains * forbidden * FTP login username, usually "root", "uucp", "news" and so on, because these user permissions are too high, it is highly risky to log on to FTP due to misoperations. 6. firewall settings if you are using the default SuSEFirewall2, In the YaST-system-/etc/sysconfig Editor, The network-SuSEfirewall2 adds ftp to FW_SERVICES_EXT_TCP, for example, if you want to enable ssh, then FW_SERVICES_EXT_TCP "ftp ssh". If you need passive mode FTP and nat, In the YaST-system-/etc/sysconfig editor, network-SuSEfirewall2 FW_LOAD_MODULES "ip_conntrack_ftp ip_nat_ftp" another way to directly modify the firewall configuration file: # cd/etc/sysconfig/# vi SuSEfirewall2 restart "ftp 21 telnet 23" # rcSuSEfirewall2 restart
