How to build a pure-ftpd Debian package for OpenVZ virtual machines (without capabilities enabled)
The pure-ftpd package that comes with Debian 5.0 (Lenny) does not start in a OpenVZ virtual machine as it is compiled with “capabilities”. This tutorial describes the steps to build a pure-ftpd Debian package with capabilities disabled:
Make a temporary directory
mkdir /usr/src/pure-ftpd
cd /usr/src/pure-ftpd
Download the source package for pure-ftpd
apt-get source pure-ftpd
apt-get build-dep pure-ftpd
Edit the rules file and add the switch “–without-capabilities”
cd pure-ftpd-1.0.21/debian
nano rules
Change the line:
optflags=–with-everything –with-largefile –with-pam –with-privsep –with-tls
to (one Line!):
optflags=–with-everything –with-largefile –with-pam –with-privsep –with-tls –without-capabilities
Build the Debian (.deb) package
cd ..
dpkg-buildpackage -uc -b
and install it
cd ..
dpkg -i pure-ftpd-common_1.0.21-11.4_all.deb pure-ftpd-mysql_1.0.21-11.4_i386.deb
/etc/init.d/pure-ftpd-mysql restart
To prevent that apt overwrites these manually compiled packages with the default packages from the Debian repositorys, execute these commands:
echo 'pure-ftpd-common hold' | dpkg --set-selections
echo 'pure-ftpd-mysql hold' | dpkg --set-selections

How to display hidden files with pure-ftpd on Debian and Ubuntu Linux
If hidden files (files that start with a dot like .htaccess, .bash_history, .profile or .ssh) are not displayed in your FTP client, then they are most likely disabled in the FTP server. To enable hidden files in pure-ftpd on Debian and Ubuntu Linux, execute this command:
echo “yes” > /etc/pure-ftpd/conf/DisplayDotFiles
and then restart pureftpd.
pure-ftpd does not show more then 2000 files on Debian and Ubuntu
The pure-ftp daemon by default has a recursion limit of 2000 files, this prevents the server from showing more then 2000 files when you browse a directory with a FTP client. To expand this Limit to e.g 5000 files, create or edit the file /etc/pure-ftpd/conf/LimitRecursion and add a line “5000 500″:
echo “5000 500″ > /etc/pure-ftpd/conf/LimitRecursion
and then restart pureftpd:
/etc/init.d/pure-ftpd-mysql restart
How to speed up logins in pure-ftpd on Debian or Ubuntu Linux by disable name resolving
If you experience problems with slow logins in pure-ftpd, this is often caused by a problem with the resolving of the clients hsotname. This happens e.g. when you run a FTP server in your intranet and the hostname of the client computer does not exist in DNS. To disable name resolving in pureftpd, run the command:
echo ‘yes’ > /etc/pure-ftpd/conf/DontResolve
and then restart pure-ftpd
/etc/init.d/pure-ftpd-mysql restart
Disabling name resolving also fixes the following error message:
Jul 24 16:26:28 ispconfig pure-ftpd: (?@?) [ERROR] Sorry, invalid address given
How to enable verbose logging in pure-ftpd on Debian Linux

echo 'yes' > /etc/pure-ftpd/conf/VerboseLog
and then restart pure-ftpd
/etc/init.d/pure-ftpd-mysql restart
The debug output will be logged to syslog. To view the log content, execute:
tail -n 100 /var/log/syslog
To disable verbose logging, execute these commands:
rm -f /etc/pure-ftpd/conf/VerboseLog
/etc/init.d/pure-ftpd-mysql restart
