= User DOs and DON'Ts = * DO read the [https://education.deterlab.net/DETERintro/DETERintro.html Student Introduction to DeterLab] if you are a student. * DON'T use control network unless absolutely necessary. This means: * DON'T use full node names such as {{{ping node1.YourExperiment.YourProject}}} * DO use short names such as {{{ping node1}}}. This ensures that traffic goes over experimental network. * DON'T generate traffic to 192.168.x.x network * DO use addresses of experimental interfaces. These can be from any IPv4 address range, depending on your NS file, but are often from 10.10.x.x address range. * DON'T store large files in your home or project directory unless you need them in multiple experiment instances. * DO store these files locally on a node, e.g., in {{{/tmp}}} folder. If you need more disk space you can mount more by doing {{{ sudo /usr/local/etc/emulab/mkextrafs.pl /mnt user=`whoami` sudo chown $user /mnt/local }}} Traffic from experimental nodes to/from your home directory also travels over the control network (read more about this in the next section). To minimize this load please refrain from performing large (> 500 MB) or frequent (< 10 s) reads/writes that involve your experimental nodes and your home directory, unless absolutely necessary. If you need to log something, use a local directory on an experimental node, such as /tmp, and transfer the logs to your home directory before you swap out to save them.
