Non-Multilib

Enable TCP Wrappers Support with the following command:

sed -i "/VSF_BUILD_TCPWRAPPERS/s/^#undef/#define/" builddefs.h

Adjust the default path to the secure chroot dir and change the default unprivilged user from nobody to vsftpd:

sed -i -e '/secure_chroot_dir/s:".*".$:"/var/ftp/empty";:' \
       -e '/nopriv_user/s:".*".$:"vsftpd";:' tunables.c

Compile the package:

patch -Np1 -i ../vsftpd-2.0.5-syscall-1.patch &&
sed -i -e '/LIBS.*=/s:`:$(shell :' -e '/LIBS.*=/s:`:):' Makefile &&
make

Configuring

Create the jail directory:

install -dv -m755 /var/ftp/empty

Create the ftp root directory:

install -dv -m775 -ovsftpd -gvsftpd /srv/ftp

If you built vsftpd against pam, Which you did unless you explicitly disabled it, you also need to create a rule for ftp.

cat > /etc/pam.d/ftp << "EOF"
#%PAM-1.0

EOF

Note

This would be a good time to reference the vsftpd.conf(5) man page and configure you ftp server

There are 2 ways to run the vsftpd daemon. The first method is to have xinetd spawn an individual process for each incoming connection. The second method is to run vsftpd as a daemon and let it manage that itself.

Xinetd

Ensure that you have xinetd installed then create the service file:

cat > /etc/xinetd.d/vsftpd << "EOF"
# Begin /etc/xinetd.d/vsftpd

service ftp
{
   disable        = no
   wait           = no
   socket_type    = stream
   user           = root
   server         = /usr/sbin/vsftpd
   nice           = 10
}

# End /etc/xinetd.d/vsftpd
EOF

Bootscript

Install the bootscript from the Bootscripts package with the following command:

make install-vsftpd

You also need to add the following to /etc/vsftpd.conf

cat >> /etc/vsftpd.conf << "EOF"
background=YES
listen=YES
EOF
