outreachy: compile and run conntest!
The instructions can be seen in the README.md. Post questions here if you e.g. have trouble compiling (:
It will also be nice if you note anything you found hard, then we can add more information to the README
Hello @rand00, I keep running into this error when I run mirage configure -t spt -f mirage/config.ml && make depend && mirage build -f mirage/config.ml
Please is it that I am missing a step?
this is the error message I get
opam-monorepo: [ERROR] Can't find all required versions.

So I learned that since mirage is not supported by ocaml v5.0.0, the command mirage configure -t spt -f mirage/config.ml && make depend && mirage build -f mirage/config.ml was not running successfully, so I am suggesting we add it to the README.md file so others will remember to change to v4.14.1.
Also running the command mirage/dist/conntest --help gives the error bash: mirage/dist/conntest: No such file or directory since there is rather contest.spt and contest.hvt and that did not work as well.
Hey @Burnleydev1 !
so I am suggesting we add it to the README.md file so others will remember to change to v4.14.1.
Indeed this would be useful (: Will you make a PR for this?
mirage/dist/conntest --help
Yes - this binary is only present if you configured for the unix target. You can also pass --help if run using solo5-spt or solo5-hvt, e.g.:
solo5-spt --net:service=tap101 mirage/dist/conntest.spt --help
.. but here you need to have setup the TAP device first, as this is a dependency of the unikernel to run as these targets
As the README currently states that you can run that command after compiling to the unix target, I don't think this is an issue.
Thanks for the report (:
Hello @rand00,

yes, I would love to add it.

Perhaps we could add the steps that can be used to run the script, the location where it should be saved, and other points that will make it easier for users to set up TAP

At the end of the README there is the 'Network setup' section. The script shown there just needs to be run from any location, as setting up a bridge and tap-devices is a global action on the system (not persisted between restarts). I'm not sure that more information is needed.
