OverviewOverview
NetIDNetID/GuestID
Your Your Cornell Netid or Guestid is used to access central Cornell services, the Coral lab management system, the CNF AFS file server, and login to the Sunrays and and Windows workstations.
Per Cornell policy, the password used for your GuestID or NetID must not be used anywhere else and must not be written down. If this password is compromised, others will be able to access your data files and charge lab time to your account.
VAX
Your Vax username and password is used to access the old web scheduling system and CAC on the vax terminals.
This password should be unique and not used anywhere else. Access to the VAX is via telnet which is not encrypted. This means that your password can easily be observed by someone else on the network.
Before being able to use CNF systems requiring the VAX password, the VAX password must be changed by telnetting to: nnfvax.cnf.cornell.edu
