You can use the *guest* account on a lab machine, but your data will be deleted on logout!
You can SSH into a CSE login machine like so:
$ ssh USER@login.cs.nmt.edu
If you'd like to use qemu graphically, you should use this ssh command instead:
$ ssh -XYC USER@login.cs.nmt.edu
There are more in-depth instructions here. Or, of course, you can log into any CSE lab machine.
Clone xv6 into your home directory as such:
$ git clone git://github.com/mit-pdos/xv6-public.git
Then build it:
$ cd xv6-public $ make
You can then run xv6 in qemu using gdb by running:
$ make qemu-nox-gdb
And then connect to qemu's gdb by running the following in gdb:
+ target remote localhost:26000
Note that the port number is subject to change and can be found as output when
make qemu-nox-gdb is run, this should be shown more in detail in your Lab 1 PDF.
If you prefer to use the magic of containers, either on your own machine or on the CSE machines, there is a Ubuntu 16.04 Dockerfile created for this class located on github.
