+"Netjail is the GNUnet naming for having several <a href=\"https://www.man7."
+"org/linux/man-pages/man8/ip-netns.8.html\">network namespaces</a>, being "
+"isolated from each other to test how GNUnet nodes with limited connectivity "
+"behave, and how the new transport next generation implementation can help to "
+"circumvent the connectivity obstacles. The network namespaces are span a "
+"network with globally known nodes and several subnets separated from each "
+"other via a single router. We have three scripts for the test setup: <ul> "
+"<li>netjail_start.sh: A script to setup the network namespaces. This script "
+"takes three arguments. The first is either the name of a configuration for "
+"the test setup topology or a string containing the topology information. The "
+"second is the process id of the test. The third is a flag if the first "
+"parameter contains the name of the configuration file or the topology string."
+"</li> <li>netjail_exec.sh: A script to run some command in a specific "
+"namespace. This script takes eight arguments. The first is the index of a "
+"node in a namespace for which we like to execute a command. The second is "
+"the index of the namespace of the node. The third is the command to execute, "
+"the fourth is the number of subnets, the fifth the number of nodes in each "
+"subnet, the sixth is the identifier used by the <a href=\"https://www.man7."
+"org/linux/man-pages/man8/ip-netns.8.html\">ip-netns</a> command, the sixth "
+"is a flag is the topology information is given via a topology file of a "
+"string containing the topology information..</li> <li>netjail_stop.sh: A "
+"script which remove all the network namespace setup by netjail_start.sh. The "
+"arguments are the same as those for netjail_start.sh.</li> </ul> The is a "
+"generic test binary (test_transport_start_with_config) which will start the "
+"above mentioned scripts. Because creating network namespaces is only "
+"permitted for privileged users the generic test binary is not start "
+"directly, but via scripts. This script starts the generic binary using the "
+"command unshare. Using unshare one can create a namespace with its own user "
+"namespace, where creating network namespaces is allowed. Precondition to do "
+"this with unshare, is to set the kernel.unprivileged_userns_clone kernel "
+"parameter."
