Usage of a reverse ssh bridge at UiO
At UiO, for security reasons, the computers which are not managed by the university should be placed on a separate network which is "deeper", it is called the 802.1X network, .1X in short. Some of our computational resources (fys-lab-flow, datacenter computer…) are on this network. As of now (Nov. 2023), it is no longer possible to ssh a computer on the .1X from a computer which is not on the .1X, which means that it is not possible to connect to fys-lab-flow from login. But, the inverse is possible: fys-lab-flow can connect to login. As an SSH connection works both ways once connected (the remote computer can send information to the connecting computer), a way to connect to computers on the .1X network is to keep an SSH connection from the computer on the .1X and login
