Well, I got it working but not sure I want to leave it that way....
1- added these lines to vsftp.conf
(hopefully these ports are not used by anything._)
commented out the line, diisabling it.
The above lines solve the issue of the ssl getting kind of lost since
the iptable module conntrack cannot quite grasp ssl dealings in this regard.
These lines set specific ports to be used for, well, for whatever the
heck vsftp needs all those ports for.
The min/max could be lower I guess, but what the heck.
IPTABLES required a nice bunch of junk too.
-A INPUT -m state --state ESTABLISHED,RELATED -m tcp -p tcp --dport 4999
-A INPUT -m state --state NEW,ESTABLISHED -m tcp -p tcp --dport 5000 -j
-A INPUT -p tcp --dport 5001:5100 -j ACCEPT
and of course you can kill the port 21 iptable listing as it will not
(could port 20 and 21 still be used? I guess so, did not test that).
I wonder how safe that is to make such a huge hole in your firewall...?
you can see where the numbers added in vsftp.conf correspond with the
iptables set up.
To finalize, here is the additions to the vsftp.conf file
so there you have it, ssl over ftp with centos 6.
Not sure how safe the whole 100 ports open thing is (you need ports to
be open depending on number of users I guess, I am gonna lower it to 20
