Unable to View Webmin from any Interface

PedroK

Hello All, 

I have done some searching for similar questions, but all results I have found were solved by either a reboot, or someone forgetting to either include the "https://" or configure their computer's NIC to be on the same subnet.

On the console of the UTM, I see the IP for Webmin as "https:192.168.0.2:4444" as expected, so this is what I am attempting to connect to. I had set this network up as a /24, so I set my laptop to 192.168.0.4/24. In theory this should work. 

I set up my UTM box quite a while ago, was able to log into the webmin portal and it was working just fine. After putting it away for some time (lab environment) I attempted to connect to the Webmin portal again and no matter what interface I plug into, the page is still unresponsive. I do not believe I made any configuration changes the last few times the device had been reloaded before this. I have performed several restarts in attempts to help, as well as restarting httpd via "/etc/rc.d/httpd restart". Nothing seems to help. 

Worst case scenario, I suppose I could copy the config and reinstall using this article https://community.sophos.com/kb/en-us/119814. However, I would really like to not have to rebuild the whole system if I don't need to. Does anyone have any suggestions on what I can try?

    Hi Pedro and welcome to the UTM Community!

    You will need to do some spelunking from the command line...

    Find the networks allowed to reach WebAdmin:

    cc get webadmin allowed_networks

    If you named one Internal, you likely will see something like REF_NetIntInternal and that's the one that we want to find.  Which NIC is it defined on?

    cc get_object REF_IntEthInternal |grep itfhw

    That should give you something like 'itfhw' => 'REF_ItfEthEth0IntelCorpo'.  That tells us that the hardware is an Intel NIC assigned eth0.

    If that didn't help you to identify the correct NIC to which you should connect, show the results here of those two commands along with the output of the following command.

    cat /etc/udev/rules.d/70-persistent-net.rules

    Cheers - Bob

    Thanks a lot for the welcome, and the reply!

    The first command, "cc get webadmin allowed_networks", gave the expected result of the second provided command (which gave no output). I have plugged into each of the available interfaces (0-3) in attempts to connect. 

    "cc get webadmin allowed_networks"   ==>  REF_NetIntEth3IntelCorpo2

    "cat/etc/udev/rules.d/70-persistent-net.rules"  followed this output format for each interface:

    SUBSYSTEM == "net",ACTION=="add",DRIVERS="?*",ATTR{address}="<mac of given interface>",ATTR{type}=="1",kernel="eth*",NAME="eth<eth number>"

    That doesn't look like something I would expect, Pedro.  Please show a picture of the command and the result.

    Cheers - Bob
