pureftp+tcpwrappers? ("libwrap refused connection to ftp")

owensleftfoot,
Thank you for your proposal. It does work in the standalone mode, but xinetd way still is more secure. If no one else will propose a way to make it work with xinetd, you will be awarded points for this question.

troopern,
It seems quite clear to me that my xinetd handling of pure-ftpd daemon is setup correctly, since it works perfectly if I allow access to all xined services from all ips using hosts.allow file. Correct me if I am wrong.

can you paste the string/xinetd.d file that starts pure-ftpd ?

/etc/xinetd.d/pure-ftpd-xinetd file:
-----------------------------------
service ftp
{
        disable = yes
        socket_type             = stream
        wait                    = no
        user                    = root
        server                  = /usr/sbin/pure-config.pl
        server_args             = /etc/pure-ftpd/pure-ftpd.conf
        log_on_success          += DURATION USERID
        log_on_failure          += USERID
        nice                    = 10
}
--------------------------------------

change disable = yes to disable = no. and it should be working just fine =)

I've changed disable from no to yes when I switched from xinetd handling of an ftp server to standalone. My apologies, I forgot to mention it.

ok.
Can you show your pure-ftpd.conf too ?

Your config file seems perfectly fine.

Though, this line:
   server                  = /usr/sbin/pure-config.pl
make me ponder some.


Cut & Paste from : http://www.pureftpd.org/README
**** Usage with Xinetd ****

Add the following entry to the /etc/xinetd.conf file:


service ftp
{
    socket_type = stream
    server = /usr/local/sbin/pure-ftpd
    protocol = tcp
    user = root
    wait = no
    disable = no
}


or something like:

service ftp
{
    socket_type = stream
    server = /usr/local/sbin/pure-ftpd
    server_args = -s -a 42
    protocol = tcp
    user = root
    wait = no
    disable = no
}

Hope this will help you.
