Dartmouth has taken steps to provide greater security for data on both administrative and research systems. One important step is the requirement for secure connections by using the SSH2 protocol to access information on servers. Insecure connections, via the Telnet protocol, pass data in clear text, including user names and passwords. Telnet programs, such as DarTerminal, do not recognize the SSH2 protocol and can no longer be used to access secure servers.
A first step in securing the College's data was the upgrade of our VMS system in March 2005. (Many institutional financial applications run on this system.) Applications were moved from old hardware to new hardware known as "Hickory." This provided the opportunity to turn off insecure access to some of the central systems.
If the system to which you are connecting allows SSH access, we recommend using one of the applications listed below. If you are unable to use one of the secure clients, we recommend using a VPN client to provide data encryption. The VPN client for both Macintosh and Windows computers is available from the Software Downloads Web page.
Specific information on installing SecureCRT to access administrative systems is available; see Using SecureCRT to Access Administrative Systems.
If you have additional questions about installing or using these applications, please contact the IT Service Desk (Help Desk) at 646-2999 and select from the options provided, send electronic mail to help@dartmouth.edu, or call your department's IT support office.
