I installed the pure-ftpd package (version 1.0.35-1) on an Ubuntu 12.04 box (an EC2 instance based on the standard Ubuntu 12.04 AMI).

The pure-ftpd daemon is running (verified with ps), though there is no PID file (expected one to be created by the /etc/init.d/pure-ftpd script).

Here's the resulting command that gets run by the init.d script:

/usr/sbin/pure-ftpd -l pam -O clf:/var/log/pure-ftpd/transfer.log -o -8 UTF-8 -u 1000 -E -B -g /var/run/pure-ftpd/pure-ftpd.pid

Here's my real problem: the ftp server isn't actually listening on any port (checked with netstat and nmap). So I can't ftp to the server (either locally using localhost or remotely using the public IP address).

I tried adding a Bind file to /etc/pure-ftpd/conf and restarting, but it didn't help.

When I installed pure-ftpd, it replaced inetd with openbsd-inetd, but did not run it since there were no services enabled. So inetd is not listening on port 21 either. (Apparently Ubuntu has a no-inetd-by-default policy, according to https://lists.ubuntu.com/archives/ubuntu-users/2010-September/227905.html .) I want to run pure-ftpd by itself (not with inetd) anyways, since the /etc/init.d/pure-ftpd script requires no inetd if you use the UploadScript feature.

I'm not familiar with how Ubuntu handles network services (and can't find any relevant docs besides generic man pages), so I'm probably missing something obvious. Nothing seems out of the ordinary with /etc/hosts.allow (empty) or hosts.deny (empty), and I didn't add any firewall rules (iptables -L shows that the firewall is in its initial state). I've checked the pure-ftpd docs; not sure what else to look at.

Any help would be appreciated, thanks!
