  1. Ssh (Secure Shell)

    For security reasons, in general it is not possible to connect to a machine inside the Math Department from outside. However, if the outside machine you are using has ssh (the secure shell) installed, then you can connect to the department entry machine by typing the command
         ssh lunt.math.northwestern.edu
    
    (If the machine lunt is not available, try lunt2.math.northwestern.edu)

    If your have different login names on the local and remote machines, type

         ssh username@lunt.math.northwestern.edu
    
    where username is your username in the department computer network.

    The connection provided by ssh is secure because all the information is transmitted encrypted.

    The ssh command works pretty much like rlogin, but you cannot use it for transferring files. For that purpose use scp or sftp. For instance, in order to copy the file foo from your home directory on the department network to the directory /tmp on your local machine type:

         scp username@lunt.math.northwestern.edu:foo /tmp
    

    The program sftp works like ftp, i.e., you open first a session

         sftp username@lunt.math.northwestern.edu
    
    and then transfer files with the usual commands put, get, etc. The session ends with exit, quit, or bye.

    Note: The secure shell (ssh) should also be used instead of telnet or rlogin for any connection between machines inside the Math Department, since it provides higher security.

    After logging in to lunt it is highly recommended that you login to some other public machine, since lunt is just an entry point to the department and has minimal software installed - for instance we will not be avaliable to check or send email on lunt.
