How to Enable Complete Virtual Hosting

Complete virtual hosting allows separate configuration files for each virtual domain. To enable complete support for virtual hosting on the FTP server, you can create or modify the following FTP configuration files for specific domains:

For further information, see ftpaccess(4), ftpusers(4), ftpgroups(4), ftphosts(4), and ftpconversions(4).


Note -

If separate versions of the configuration files are unavailable, master versions of the files in the /etc/ftpd directory are used.


  1. Become superuser.

  2. Add the following entry to the /etc/ftpd/ftpservers file.


    address /config-file-dir
    

    address

    IP address of the virtual server 

    config-file-dir

    Directory that contains the configuration files that are customized for the virtual host 


    Note -

    While it is possible to use hostname as the address of the virtual server, you are strongly encouraged to use the IPv4 address instead. DNS must be available when the FTP connection is received in order for hostname to be matched. For an IPv6 host, use the host name rather than the IPv6 address.


  3. To create a customized version of an FTP server configuration file for the virtual host, copy the master version of the file from /etc/ftpd to the /config-file-dir directory.

    For further information, see ftpservers(4).

Example-Enabling Complete Virtual Hosting


#
# FTP Server virtual hosting configuration file
#

10.1.2.3 /net/inet/virtual/somedomain/
10.1.2.4 /net/inet/virtual/anotherdomain/

The preceding example specifies the IP addresses for two different domains on the virtual server.


Note -

The ftpaddhost(1M) script with the -c option is provided to configure complete virtual hosts.

In the following example, ftpaddhost is run with -l -b -x options to configure limited virtual hosting with a test banner and the logfile /var/ftp/virtual/10.1.2.3/xferlog under a virtual root /var/ftp/virtual/10.1.2.3.


ftpaddhost -l -b -x /var/ftp/virtual/10.1.2.3/xferlog \
/var/ftp/virtual/10.1.2.3
