Every user with a COR@L account can access the machines listed here using her/his username and password. However, if you are outside Lehigh’s network, then you need to log into shark.ie.lehigh.edu or coral.ie.lehigh.edu and then ssh into another machine on the list. Please keep in mind that shark is the file server and coral is the web server. Therefore, these two machines should not be used for big and/or long running jobs. If you have such a job, then please use another computer in the list.
If you are a Linux user, then logging into COR@L is straightforward. The following command uses ssh, which is typically available on standard Linux distributions:
Your COR@L username and password is the same for all machines. COR@L uses NIS to manage passwords, so passwords can be at most 8 characters long. Any extra characters will be ignored. If you wish to change your password, then do not use the passwd command. Use yppasswd instead.
If you are using Windows and want to sign into a COR@L machine, then you need to install an ssh client first. There are several free software options. You can check Wikipedia for more information about your choices. A common free ssh client is putty, which can be downloaded here. This ssh client is easy to use and it is well documented here.
