Network Frequently Asked Questions

My office computer is not connecting to the building network. What should I do?

If possible, contact the computer support staff with your name, office number, the date and time when the problem occurred, and any other details you consider relevant. Otherwise, call the math department office (621-6892) and ask for the computer support staff to be contacted on your behalf (with the same information as requested above, along with a telephone number for reaching you).

My department-owned laptop is not connecting to the internet from home. What should I do?

Please contact the computer support staff to arrange a time for us to meet with you and your laptop.

My home computer is not connecting to the University network. What should I do?

Contact your internet provider and/or computer support service. If you are using one of the CCIT modems, call 621-HELP.

I have a personal laptop that I sometimes use in my office. Can I get a building network connection?

Please see this page.

My network access has been blocked. What should I do?

CCIT blocks infected computers. You'll need to eliminate all malware from your computer, also ensure your virus protection is up-to-date, and that all your operating system patches have been applied (in the case of Microsoft Windows, you must run Windows Update, install all updates, reboot, again run Windows Update, install all the new updates that are now available to your system, reboot, and keep repeating this cycle until there are no more updates to be installed). Once your computer is clean, up-to-date, and protected, please contact the computer support staff and we will ask CCIT to unblock your computer.

How do I determine whether my virus-protection is up-to-date?

If you're running SophosRU (and you should be!), simply hover your mouse over the SophosRU icon in your system tray (lower right of screen, the icon is blue dots arranged in a circle): you will be informed when the last update took place. Double-click the icon to force an immediate update.

How do I see the printjobs in the queue and remove my job?

If you're still on the computer from which you submitted the job, use the command lpq -a. Or in general, you can use the command lpq -a -h printserver.

To remove a job, if you're still on the computer from which you submitted the job, use the command lprm jobnumber, where the jobnumber can be seen in the output from lpq (see previous paragraph).

If you're on a different computer and need to remove your job, use the command lprm -h printserver -U yourusername jobnumber.

There exist other printer-related commands that start with “lp” (which stands for “line printer”). Type lp and then hit TAB a couple times to see a list of possible command completions. To learn more about a particular command, take a look at the built-in manual page, e.g., man lpq.
