First, my setup. I'm using CentOS 6.4 and I installed pure-ftpd (plus the SELinux module) from the EPEL repositories :
> rpm -q pure-ftpd pure-ftpd-selinux
pure-ftpd-1.0.30-1.el6.x86_64
pure-ftpd-selinux-1.0.30-1.el6.x86_64
After struggling with getting this to work with SELinux properly, I tried setsebool
'ing a few things :
allow_ftpd_full_access --> on
ftp_home_dir --> on
ftpd_use_passive_mode --> on
The context in which pure-ftpd is running (as root.root
) :
system_u:system_r:ftpd_t:s0-s0:c0.c1023 25196 ? Ss 0:00 pure-ftpd (SERVER)
Now, the problem. For some unknown reason, SELinux denies login attempts without logging at all to /var/log/audit/audit.log
. pure-ftpd logs this (in -d -d
mode) :
Jul 10 17:53:39 <hostname> pure-ftpd: (?@<my_ip>) [INFO] New connection from <my_ip>

When I setenforce 0
, the login suddenly works perfectly fine. When I then setenforce 1
again and reconnect, it won't let me login.
Again: auditd doesn't log anything and the pure-ftpd logs are useless. /var/log/secure
also stays empty and tail -f /var/log/*
only shows the syslog messages I pasted above.
For completeness, he's my pure-ftpd.conf
:

Your help would be very much appreciated.
