Does your university/college provide support for Linux/BSD/etc users to connect to the on-campus wireless?
We support Mac OS X, MS Windows and Linux. Our Technology Services Help Desk has instructions for how to connect to wireless using the example of Ubuntu, but there is nothing proprietary about the wireless access which would cause issues for Linux users specifically.
How does IT support Linux users generally?
Computer Science students are given accounts on a Linux server for use in developing code, but they are also encouraged to install either a dual boot or virtual system with Linux on their laptop (all students have laptops). Students in other studies can also use Linux on their laptop and get assistance with typical Help Desk issues like network access, email client, etc. Our campus has roughly 40% Mac OS users, so we've grown to be flexible in offering whatever support we can to make things work beyond systems running MS Windows.
On the services offered at Acadia, we use quite a bit of open source and Linux. We run Debian and Redhat on a few dozen servers. Email is cyrus, webmail is horde, mail MXes are postfix with amavis, and our main web site runs Contao CMS. Our LMS system is moodle. We like using open source whereever it fits well, and it saves us money.
Have IT staff ever ridiculed you for asking questions about Linux?
I've never heard of it. Help Desk staff might be confused about some specialized questions, and seek additional assistance, but it would be unprofessional to ridicule a student for any question they might have. In our view, the student is the customer, and we seek to provide them with the support they need to succeed in their studies.
