How should I request course based file services?

For a course use http://www.colby.edu/acits/fileserverfolder/

I need a commercial software package, how do I request it?

Use the online request form: http://www.colby.edu/its/software/sw-request-form/

 

Did the ssh key for nscc/fangorns etc. change?

Yes, on rare occasions I have to update server based host keys. You will need to remove the old one in order to make a ssh connection.

The ssh key is stored in your home directory, within the .ssh directory, in a file named known_hosts. Either delete the file (‘rm ~/.ssh/known_hists’) or remove the offending line with your favorite text editor (‘vi ~/.ssh/known_hosts’).

 

Recently I have been forced to use https, why?

This is going to happen on more and more domains through the use of HSTS (more info).
I entered http://cs.colby.edu and it was switched by the browser to use https://cs.colby.edu I don’t want this to happen, what can I do? One solution is https://andystechlife.wordpress.com/2016/09/18/how-to-clear-hsts-settings-in-chrome-and-firefox/.

 

How can I change my shell?

On a Unix host a standard user can change their shell with the command  chsh

man chsh

Will show you the options for using the command and you can find out what shells can be used by

typing          cat /etc/shells

 

Here is the typical output of that:

/bin/sh
/bin/bash
/sbin/nologin
/usr/bin/sh
/usr/bin/bash
/usr/sbin/nologin
/bin/tcsh
/bin/csh

Is there a tool to test my regular expressions (REGEX)?

Yes, there is a wonderful online resource: https://regexr.com/

 

Something in IT is wrong what’s broken?

The best 10,000 ft (think what would Doug, Cindy or David need to know) is http://its-status.colby.edu/.

If you want, you can sign up for text alerts if something changes there.

 

Can I do anything to protect my privacy on the internet?

Yes! For starters switch to duckduckgo for all web searches.
