Posting On Sandbox
The Sandbox Linux server is available for posting web pages. You each have regular shell accounts there. The account password is independent of your MC password. Here are some notes on using it.

How to Post a File

Each account has a home area where you can store files. These are not visible on the web. The web serves file in the subdirectory local_html. So, you might create a file page.html as a local file on your own machine. You can view it in your browser, but it won't be visible on the wider Web. To get it there, you need to copy it into the local_html directory on your account is Sandbox. Assuming your account name is joeuser, on the command line this would look like this:
bennet@bennet:~$ scp page.html joeuser@sandbox.mc.edu:local_html joeuser@sandbox.mc.edu's password: page.html 100% 157 5.4KB/s 00:00 bennet@bennet:~$
The password does not appear when you type it. (This is the command-line version of putting stars in the entry box in a browser or such.) Your page is now visible on the web either as https://sandbox.mc.edu/~joeuser/page.html or https://sandbox.mc.edu/homes/joeuser/page.html.
You can use the scp command from a Mac, Linux or Windows shell window. They all come with it these days. If you prefer a GUI tool to transfer files, there are several available. The WinSCP program which runs on Windows and allows files to be dragged back and forth between the remote and local file systems. It also allows remote files to be edited in a local window. There is also FileZilla, which runs pretty much anywhere. Its interface is rather more clunkly than WinSCP, but can be used in more places. I'll also take suggestions from Mac people, if you know of any nicer ones there.

Command Shell

You also have regular shell access on Sandbox, which can be reached with the ssh program. You are free to use this, but there will be little or need for this. If you would like to, and are unfamiliar with the Unix shell, there is a nice introduction here. One command you might want to know in any case is passwd, to change your login password:
bennet@bennet:~$ ssh joeuser@sandbox.mc.edu joeuser@sandbox.mc.edu's password: Last failed login: Tue Aug 20 13:22:54 CDT 2024 from 10.27.2.212 on ssh:notty There were 3 failed login attempts since the last successful login. [joeuser@sandbox ~]$ passwd Current password: New password: Retype new password: passwd: password updated successfully [joeuser@sandbox ~]$ logout Connection to sandbox.mc.edu closed.
As above, passwords are not shown when you type them. This is to thwart shoulder surfing.
