In the class which I have managed the infrastructure for, we have 1 to 2 students per VM, so this is less of an issue and there aren't any restrictions.

One of the reasons we provide the VMs is so that students can experience working in a remote server environment. The concern that I have is that these remote ssh tools allow you to bypass learning/practicing how to perform basic actions, e.g. cd, read/edit files.

Granted, as mentioned, you can scp/rsync (or git pull), but at least this seems to be more appropriate when you eventually need to interact with a real production server.

In addition, there are also impacts on other protocols such as ARP, DHCP, ICMP, DNS etc.

So it's not as simple as changing only the IP packet format either.
