Access to the SUN computer "condor"

The ET181 course uses a SUN SPARC 10 computer (called condor) which is located in Room 265 Stocker Center (Dr.Iz's office) and can be accessed remotely through the College ethernet system. You will be given an account only on this computer. There are two distinct modes of access, depending on what you would like to do. The "telnet" access mode allows a remote PC to behave as a "dumb terminal" of the SUN computer, whereas the "FTP" (File Transfer Protocol) allows the transfer of files between a PC and 'condor'. You cannot mix modes of access and will have to decide a priori which mode you wish to use. In the ET181 course you will use both modes of access, as required. The following options are available for a "telnet" access to "condor":

Using the PCs in one of the Stocker Computer labs, Room 308, or in Rooms 127 or 267:
All the PCs in the Stocker center require to be accessed through a user name and password. Follow the instructions on the PC to complete the PC logon, and the continue as follows:
a) Using the mouse, select Start and click the left mouse button.
b) Guiding the mouse, select Programs and then ET181. The various application programs which will be used in the ET181 course will appear, including the condor telnet application.
c) Select the condor program, click the left button of the mouse, and proceed with the "condor" login process below.
Connecting through a computer and modem not in Stocker. The most convenient approach here is to obtain a Dialnet or a Resnet account, which is available in the HDL center (opposite the Station Apartments in West Union street). This includes a handbook and software to access the OU internet, FTP and Telnet facilities.

You are now ready to telnet: "condor" and login

Dr. Paul Deering has told us that because of security concerns, we should preferably use the ssh (secure shell) for logging in to condor and that telnet may be removed in the near future. One cannot use ssh from the web, so either use the ssh application from the ET181 program set, or from a terminal window use the following command:

ssh -l (login-id) condor.ent.ohiou.edu

b) Your login id will be set to your last name followed by your first initial (up to a limit of 8 characters). The first time you login you will be requested to enter a password of your choice. Subsequent logins will use the following format:

SunOS 5.6
login: smithj
Password: xxxxxxxx

c) A login message follows giving you the latest items of information on the system, followed finally by the condor prompt indicating a successful login. You may change your password at any time as follows:

condor{smithj}1: passwd
changing old password for smithj
Old password: xxxxxxxx
New password: yyyyyyyy
Re-enter new password: yyyyyyyy
condor{smithj}2:

Logout - To log out of a UNIX system either press "ctrl+D" or type logout. Then on the PC, either select Exit under the File menu, or select the X on the top right corner of the window and click the left hand mouse button. Finally, to log out of the PC, select Start and click the left mouse button, then select Shutdown and choose: Close all programs.., and select the button Yes.

Do not switch off the computer at any time.
