Port 25 nicht erreichbar von aussen - Port 25 not reachable from outside

    Hallo,


    ich bin gerade etwas verwirrt.
    Also ich habe 2 vServer (mit OpenVZ erstellt) auf dem gleichen Root-Server am laufen.
    Beide haben das gleiche VZ-Image (Debian 7 x86_64).
    Auf beiden habe ich die gleiche i-MSCP Version (1.1.11) installiert.


    Bei einem (black) ist der Port 25 von außen erreichbar, beim anderen (green) nicht.
    In iptables steht folgendes:


    Code
    1. Chain IMSCP_INPUT (1 references)target prot opt source destination tcp -- anywhere anywhere tcp spt:submission tcp -- anywhere anywhere tcp spt:ssmtp tcp -- anywhere anywhere tcp spt:smtp tcp -- anywhere anywhere tcp dpt:imaps tcp -- anywhere anywhere tcp dpt:pop3s tcp -- anywhere anywhere tcp dpt:submission tcp -- anywhere anywhere tcp dpt:ssmtp tcp -- anywhere anywhere tcp dpt:smtp tcp -- anywhere anywhere tcp dpt:imap2 tcp -- anywhere anywhere tcp dpt:pop3 tcp -- anywhere anywhere tcp dpt:https tcp -- anywhere anywhere tcp dpt:httpRETURN all -- anywhere anywhereChain IMSCP_OUTPUT (1 references)target prot opt source destination tcp -- anywhere anywhere tcp dpt:submission tcp -- anywhere anywhere tcp dpt:ssmtp tcp -- anywhere anywhere tcp dpt:smtp tcp -- anywhere anywhere tcp spt:imaps tcp -- anywhere anywhere tcp spt:pop3s tcp -- anywhere anywhere tcp spt:submission tcp -- anywhere anywhere tcp spt:ssmtp tcp -- anywhere anywhere tcp spt:smtp tcp -- anywhere anywhere tcp spt:imap2 tcp -- anywhere anywhere tcp spt:pop3 tcp -- anywhere anywhere tcp spt:https tcp -- anywhere anywhere tcp spt:httpRETURN all -- anywhere anywhere



    Weiß jemand, wie ich den Port nach außen hin öffnen kann?


    I´m a little bit confused.


    I realized 2 vServer using OpenVZ on a root server.
    on 1 machine port 25 is reachable from outside, on the other it isn´t.
    both machines are running the same linux image and the same i-mscp release (1.1.11)


    output from iptables --list and telnet -> see above.


    has anyone a solution to open port 25 for outside connections?

    Hello ;


    On second server, you are using IPv6? Dual protocol (postfix) is disabled by default. See the main.cf to enable it.


    Default is as:

    badge.php?id=1239063037&bid=2518&key=1747635596&format=png&z=547451206

    SSH key for online support

    thx for your help.


    i disabled the ipv6 part in /etc/network/interfaces and started the machine new.
    this helped. ;)

    Restarting the network would have been enough. Restarting servers is for windows, restarting services is the Linux way. (/etc/init.d/networking restart)

    I know that networking restart should be enough but on OpenVZ this is not working every time and a restart of the VM in 15 sec. is ok. ;)
