WU-FTPD 2.4 Release Notes

26 WU-FTPD Release Notes for Version 2.4

Virtual ftp Support

Virtual ftp support allows you to manage an ftp server for two separate

domains on the same machine.

Basically, virtual ftp allows an administrator to conﬁgure systems so

that user1 connecting via ftp to ftp.domain1.com gets one ftp banner and

ftp directory, while user2 connecting via ftp to ftp.domain2.com gets

another banner and directory. (This occurs even though the users are on

the same machine and are using the same ports).

NOTE Setting up a virtual ftp server requires IP address aliasing. This feature

is supported in HP-UX Release 10.30 onwards.

Setting Up a Virtual ftp Server

Following is an example of how to set up a virtual ftp server:

1. Set up an IP alias for the ftp server machine using the ifconﬁg

command. For example,

ifconﬁg lan0:1 15.70.178.100 netmask 0xffffff00 up

This will set 15.70.178.100 as an IP address alias for the interface

lan0. Now you can access that particular machine with this IP

address.

2. Declare the following directives in the /etc/ftpd/ftpaccess ﬁle:

virtual 15.70.178.100 root/virtual

virtual 15.70.178.100 banner / virtual/banner.msg

virtual 15.70.178.100 logﬁle / virtual/xferlog

3. Create the /virtual directory and banner.msg and xferlog ﬁle inside it.

4. Login as anonymous on the virtual ftp server (ftp 15.70.178.100): it

will display the banner.msg from the /virtual directory.

An anonymous user will be chrooted to the directory speciﬁed in the

"virtual <IP ADDRESS> root" entry as speciﬁed in the

/etc/ftpd/ftpaccess ﬁle. In this example, the user will be chrooted
