There have been a few instances lately where a person’s Facebook account has compromised and unwanted content has been posted on behalf of that person. As a result, the unwanted content then appears in the news feeds of friends. If this has occurred, you can remove the post from your feed by reporting it as spam by clicking on the little down arrow next to the post and select Report Story or Spam.
The IT department is responsible for the security of sensitive information about students, families, and employees. We maintain network systems that protect computers, encrypt login, and block hacking attempts. If your password is compromised, then hackers gain access to confidential information.
- Your password must be at least 10 characters in length.
- You cannot have used this password at Catlin Gabel within the last year.
We suggest inventing a simple phrase that is a few words in length. Adding a number or special character can make your password even more secure. The Upper School attendance system actually requires a number or special character. Please update your password as soon as possible so that you do not lose access to network systems.
How to Change Your Password
Go to Webmail and login to your account. Click on the Gear icon located at the top right-hand corner of the screen:
At the change password screen enter your old password once and your new password twice. Be sure that your new password is 10 characters long. It cannot be the same as your old password.
Be sure the SAVE your password change by clicking on the SAVE button located above the picture of the keys.
Your computer and network passwords are stored separately. If you want them to match, then change your Mac password in System Preferences.
Faculty, staff, and Upper School students may change their network password directly through Windows.
Press Ctrl-Alt-Delete on your keyboard to display the Change Password option. Be sure to do this while ON CAMPUS.
Upper School Attendance
The Upper School attendance system stores your password separately. Please visit the attendance system and update your password there as well.
Are You Interested in More Detail?
Security experts vigorously debate the best way to ensure password security. We are siding with length over complexity for the following reasons.
Keeping all other factors equal, longer passwords are harder to crack.
People don't tend to use true complexity.
94 characters are available on the typical keyboard, but people use only 34 of them on average. Complex passwords are rarely actually random.
Password policy is an exercise in keeping ahead of the hackers.
Entropy calculations are based on character length. Counting words instead of characters makes passphrases less attractive. As hackers make the transition to brute force word attacks, the Catlin Gabel password standard may need to change as well.

What are the storage limits?
The per user disk storage limit is 10 GB. You will start to receive warnings when you reach 80% of your limit.
How can I find out how much of my allotted disk space is left?
For Mac users, open your server folder, and the text at the bottom of the window tells you how much of your limit remains.
How can I find out what is taking up all that space?
Then click More Advanced Options
Then click the down arrow under Look in: and select your (H:) drive.
Under "What size is it?" click on the radio button Large (more than 1 MB)and under Type of File select (All Files and Folders). Click Search.
After clicking search you'll see a list of all your files over 1 MB in size. Click on the word Size at the top of the column to sort all the files by size. Clicking the top of the column twice sorts the size from largest at the top to smallest at the bottom. This will assist you in determining which are your largest files and in what folders they are stored.
Check Calculate all sizes.
After some time, size values will appear.
In any folder, click the size column header to show the largest files at the top.
Looks like my backup is taking up my a big chunk of my disk limit. How can I make sure my backup is properly configured?
How to use IBM ThinkVantage Access Connections and Cisco Clean Access Agent to log into a wireless network.
Connecting a ThinkPad to a wireless network requires two steps, which must be completed in order.
1. IBM ThinkVantage Access Connections must locate and join a wireless network.
2. If you are on campus and connected to the CGS wireless network, you must log into Cisco Clean Access agent to be able to use the wireless network.
The following screenshots explain parts of this process.
This is the IBM ThinkVantage Access Connections icon, located in the task manager in the lower right-hand corner of the desktop, near the clock.
Roll over the Access Connections icon to find out your status. The following screen shot is an example of a working connection, because the computer is connected to CATLIN (not openwireless), and the IP address starts with 10.105.
Double-click on the Access Connections icon to open its window. Use this to manage your wireless connections, not the Windows built-in wireless management utility. The following screen shot shows a working connection to CGS at about 60% signal strength.
Click the Find Wireless Network button or select it from the Wireless Network menu. This shows all of the wireless access points available within range of the computer.
To connect to a specific network, click on the radio button next to the network you want to connect to and click on the Connect at the bottom of the window. If connecting to this network requires a password, you'll be asked to enter it at the next screen. If the network does not require a password you should see a successful connection status window.
This is the Cisco Clean Access taskbar icon.
Roll your mouse pointer over the icon to view your connection status. The screenshot below illustrates a good connection.
Right-click on the Cisco Clean Access Agent icon to log in or log out of the Cisco Clean Access Agent. Sometimes, logging in and out can resolve connection issues.
Openwireless is Catlin Gabel's public wireless network.
The "openwireless" network is designed to provide internet access to parents, visitors, and friends of the school. Students and employees should use wireless network named "catlingabel."
Openwireless is not on our local area network. It provides access only to the internet. If you connect to openwireless, you will not be able to print, access the file server, or run Microsoft Outlook. Openwireless will behave much as your internet connection from home. You will be able to access the Catlin Gabel web sites, including insideCatlin, through openwireless.
Openwireless is an unprotected, unsecure network. It requires no password, nor does it encrypt traffic. This means that one should not use openwireless to transmit sensitive information, unless you are connecting via a secure (https://) web site.
Full network users (students and employees) will normally not find it necessary or desirable to connect to openwireless. Parents and school guests will find it useful. However, if you cannot connect to cgs and can live with internet access only, then you may find it useful to have a second option. How can you find out what network you have attached to? On a Mac, check the Airport icon in the menubar. On a ThinkPad, open IBM Access Connections in the task bar.
