So my question is much like this one, Port scan revealed port 1111 open. What is it?, but I wasn't able to investigate with the same techniques suggested here, because the device runs busybox. for example, netstat isn't an option.
I did an internal scan, with OpenVas, via OSSIM, and found this port open. It doesn't seem to be open from the outside. It also found port 22 open, which doesn't seem to be the case. At least I can't actually SSH to it.
I'm not super knowlegeable about any of this, but I do find it odd that my modem/gateway router should have services like this. Based on the link posted above, I wonder if my dsl company somehow uses, it? But I don't see any other hits about the actiontec and this port.
the model of the device is Model Number: Actiontec GT701-WG
