I have the following setup:
Computer A has a Wifi-USB adapter (and is a robot, so it doesn't need real internet access). It's running Ubuntu 14.04. Computer B is my Laptop running Ubuntu 14.04 also.
What I have done is setup a local Wifi hotspot on Computer B using this guide. It has an ethernet cable connected to it, which gives it access to the "outside". It works fine, computer A can join the network and I can ping computer A from Computer B and the other way around.
However, I cannot ssh from Computer B to Computer A, I always get the following error.
ssh youbot@ComputerA.local
ssh: connect to host ComputerA.local port 22: Connection refused
To my understanding I do not need to install openssh-server on Computer A, since I am only trying to ssh while in the same network. (Is this correct?)
If I run
sudo iptables -L
I get the follwong output: Computer B:
Chain INPUT (policy ACCEPT)
target prot opt source destination
ACCEPT udp -- anywhere anywhere udp dpt:bootps
ACCEPT tcp -- anywhere anywhere tcp dpt:bootps

Computer A:
Chain INPUT (policy ACCEPT)
target prot opt source destination
Chain FORWARD (policy ACCEPT)
target prot opt source destination
Chain OUTPUT (policy ACCEPT)

I have ufw disabled on both computers. Since I am really not a ssh expert, can anybody tell me what I can do to fix this?
If further information is needed, I'd be glad to provide it.
