FAIL: ftp per_source_limit from

[JuanCar]

When I send files to my through FTP, the server cuts connection and I get this message in messages log file

FAIL: ftp per_source_limit from xxx.xxx.xxx.xxx

xxx.... my IP

And I've observed the connection is closed and opened during the transfer.

Which is the cause of this behavior?

I avoid disconnection adding per_source=unlimited in /etc/xinetd.d/ftp_psa
But I see this entry in the same message log

mod_delay/0.7: unable to open DelayTable '/var/proftpd.delay': No such file or directory

Any info about this?
Thanks

You have a configuration file called "/etc/xinetd.d/ftp_psa" for PROFTP, which looks like this:

#ATTENTION!

service ftp
{
   flags       = IPv6
   flags        = IPv4
    disable    = no
    socket_type    = stream
    protocol    = tcp
    wait        = no
    user        = root
    instances    = UNLIMITED
    server        = /usr/sbin/in.proftpd
    server_args    = -c /etc/proftpd.conf
}

Please consider adding "per_source = UNLIMITED" right under "instances = UNLIMITED" and restart xinetd with the command "service xinetd restart", to avoid the described issue.
