    Hi there,

    i’ve installed the printserver on my odroid u2/u3 max2play but i can’t see the printserver web interface?! The site http://max2play:631 won’t open, any ideas?

    Dear wenkman,

    Please have a look at this webpage:


    You also could try to uninstall and install the plugin again.

    Thank you for the help, but the printserver web interface http://max2play:631/ still doesn’t open. Is there a way to check if it really is running? Maybe some telnet / shell process ID I could have a look at?

    Dear wenkman,

    you can try to do a simple test to see if the port accepts connections. you can use the nc command and the”-vz” option:

    nc -vz IP_Address Port

    for more information you can have a look at:

    nc: connectx to port 631 (tcp) failed: Connection refused

    Dear wenkman,

    Please make sure that you disabled IPv6 on the raspberry settings page, because enabling IPv6 could cause broken links. and then you can check the CUPs service using this commands:

    nmap -v -sV localhost -p 631
    sudo netstat -tnlp | grep :631

    And please check the firewall settings if you are accessing the Print server from outside.

    for more information, please check the following webpage:

    Ok. Thanks so far. CUPS is listening on port 631 and I can get to it via wget from my max2play device (odroid), so the service seems to be Ok and running – but I cannot reach it from any other device in my network (Notebook, iPad, PC…) . So maybe it is some firewall issue? I only have a FritzBox router, I thought there was no port blocking or additional firewall there in my local network. Does anyone have any more ideas?

    … and „Logitech Media Server“ is reachable via „http://max2play:9000“ without any problems, printserver on „http://max2play:631“ not. Any more ideas?

    20. Februar 2017 at 13:16 #27037

    Hi wenkman,

    Please can you check iptables firewall. iptables is a user-space application program that allows a system administrator to configure the tables provided by the Linux kernel firewall. you can change the configuration to allow port 631 to accept data packets. Please check the following webpages:



    20. Februar 2017 at 20:11 #27061

    iptables is not installed on my maxplay/odroid. Is it even possible that there is the problem? shall I install it via apt-get?

    20. Februar 2017 at 20:58 #27063

    installed it. appended some rule. now it looks like this:

    Chain INPUT (policy ACCEPT)
    target prot opt source destination
    ACCEPT tcp — anywhere anywhere tcp dpt:ipp
    ACCEPT tcp — anywhere anywhere tcp dpt:ipp

    Chain FORWARD (policy ACCEPT)
    target prot opt source destination

    Chain OUTPUT (policy ACCEPT)
    target prot opt source destination

    … still doesn’t work…

    20. Februar 2017 at 23:31 #27068

    got it.

    cupsctl –remote-admin

    21. Februar 2017 at 11:48 #27073

    Dear wenkman,

    On Max2Play the remote administration is enabled by default, but thank you to write the solution to enable the remote administration for CUPs.We are happy that your problem has been solved.
