    Hello,

    I have a strange problem with FTP connections to a Plesk server running ProFTPd on CentOS. The problems occurs on various times. When i connect to the server it goes well but then after a couple of seconds/minutes (random) it stops working an the connection is being reset/stopped.

    The problem occurs on various systems connecting trough FTP. Firewall 21 is open. When i restart xinetd it seems to be working for a couple of minutes and then the problems keep coming back.

    See content of xfertrace in attachment, this is a copy of when the connection was being reset after i opened test.php en tried to save it back trough FTP (Zend PHP IDE):

    Can someone help me any further?

    Did you tried to perform a local telnet on port 21 ?

    Coolcap, yes that works as expected:

    user@server:~$ telnet localhost 21
    Trying 127.0.0.1...
    Connected to localhost.localdomain (127.0.0.1).
    Escape character is '^]'.

    Abdi, the /etc/hosts file is not touched its default:

    # Do not remove the following line, or various programs
    # that require network functionality will fail.
    127.0.0.1 localhost.localdomain localhost
    ::1 localhost6.localdomain6 localhost6
