class Host in node.py is modified as follows:

• inherited function startShell is extended to create a symlink to /proc/<host-pid>/nsnet in /var/run/netns with name convention mininet:<host-name> .
• inherited function terminate is extended to remove the hence created symlink.

For example, /var/run/netns/mininet:h1 for host h1.

This removes the need for extracting host-pid for running

mnexec -da <host-pid==??> zsh -ils

and the other nuissance associated with it like captured KeyboardInterrupt, etc.

This also replaces the xterm h1 and gterm h1 in case one wishes to use any other terminal like QTerminal in Kali for this.

Now the net-namespace of h1 can be accessed as:

ip netns exec mininet:h1 zsh -ils
