Connect to an Ethernet network without plugs and sockets

I want to connect to a network without any sockets. As far as I'm aware the network is a data bus line of transmit and receive meaning its not a loop network. Please correct that if it's wrong.

Basically I need to remote desktop to a computer 30 floors down and up here there are no sockets. The network wires straight into the controller.

What I hope it to be able to temporarily connect, possibly with crocodile clips for easier use, to the bus line with an Ethernet plug on the end, into a wireless router. Then I can Rome the floor with my laptop and control the computer downstairs.

I believe the network is 10baseT but can't confirm that. But is there anything wrong with this idea? I would need a fixed ip for the router. Is that possible? Would I need an access point instead (I think some routers can do both) then it won't need an ip?? I think.

Can any see flaws in this?

A bit more investigation shows there MAY be an Ethernet socket on the board. If so, I should able to plug this into a wireless router, plug the router back into the board and have the router set an as access point. This should then allow the network and ip addressing to continue as normal (fixed ips) and then I can wifi to the network and remote desktop the computer.

Riiiight??? I think I'm on the right track thinking the router should be a wireless acces point as it doesn't require any ip addressing. At least I have set up a home network like this before and the primary router still dished out the ip addresses with DHCP and the access point only related them. So with this set up the access was only another point to connect to. Otherwise an invisible member of the network. At least that's what I think

I could be wrong but I'm pretty sure you can't simply take a feed off of that cable, your bet is to split and plug the cable, dunk your own hub in there when you need a line, stick a female to female cable extender in when you don't.

Ps your access point won't be invisible and neither will the hub, you are risking a ton of grief by doing this.

Well that sounds shit. If there is a plug though I could connect a hub and then go out to a wireless router and connect to the network from there.

The trouble is there are no hubs, the are no points to connect to the network, there are 30 floors each with 3 plant rooms and this is a secure building so it's difficult to get through any door. Once I'm through a door however I'll be fine. Hence the wifi idea.

The hubs are normally used with another type of network we use but this building is a bit different with a different manufacturer and different design for the plant. So I have to make do.

Surely if you got a use for it they'll just give you a pass?

Tunnelling as in ssh. Presumably the other machine has the internet? And you have some form of physical access to at least one other machine on that network?

Unless its old coax thicknet cables then tapping in wont work. Also depends on how the network is setup, if its all static IP with no DHCP then you wont be able to use it.
