Instructions for Students Setting Up the Unix Account

Each student who registers classes in Computer Science should have a Unix account. These are the instructions for a student who want setup the new Unix account:

  1. User Name:
    • For old accounts, the user name for the Unix account should be the last name of the student. If the last name is more than eight letters, it should be the first eight letters. It may be the first seven letters of your last name plus the first letter of your first name if there are many students have the same first eight letters of their last name.
    • For new accounts, the user name for the Unix account is the same as your eRaider username.
    • If you still have problem to find your user name, please send e-mail to the system administrators with your SSN or your Mac Number (if you don't have a SSN). We will find it and e-mail to you.
  2. Password: The default password for your Unix account should be your SSN or your Matriculation Number. When you login to your account first time, you must change your default password to your private one.
  3. How to SSH from a windows system? One-way is to download Putty. It is one of the most a simplest. There are other programs. You can run Putty as a stand-alone executable. You have to enter host name of one of the UNIX machines and select protocol of SSH. Doing this will not give detail like being on a UNIX machines (like the password restrictions)
  4. How to Change the default password? The best is to go the lab PE119, and login to any of the Sun Solaris Boxes. It will give more detail than SSH on the frist logon. Another way is to SSH to one of the machines listed in URL http://www.cs.ttu.edu/resources/facilities/students_machines.php. Below is an example: # ssh test@ficus.cs.ttu.edu (input your username in place of "test") The authenticity of host 'ficus (129.118.29.59)' can't be established. RSA key fingerprint is fa:35:99:9a:70:88:d8:86:33:1a:4f:09:cd:7c:3e:47. Are you sure you want to continue connecting (yes/no)? yes Warning: Permanently added 'ficus' (RSA) to the list of known hosts. test@ficus.cs.ttu.edu's password: (input your default password) Warning: Your password has expired, please change it now Enter existing login password New Password: (input your private password) Re-enter new Password: (input your private password again) sshd: password successfully changed for test sshd: credential information changed for test The Mac's in PE118 will let you logon and not prop you to change password but for secuity reason please change your password! Open a terminal window from Appliction/Utities and follow the directions bellow: # ssh test@ficus.cs.ttu.edu (input your username in place of "test") The authenticity of host 'ficus (129.118.29.59)' can't be established. RSA key fingerprint is fa:35:99:9a:70:88:d8:86:33:1a:4f:09:cd:7c:3e:47. Are you sure you want to continue connecting (yes/no)? yes Warning: Permanently added 'ficus' (RSA) to the list of known hosts. test@ficus.cs.ttu.edu's password: (input your default password) Last login: Mon Feb 12 17:44:18 2007 from netboot001.cs.ttu.edu [test@ficus:~]$ passwd passwd: Changing password for test Enter existing login password: (input your default password) New Password: (input your private password) Re-enter new Password: (input your private password again) sshd: password successfully changed for test sshd: credential information changed for test
  5. Changing the password after initial setup: You can change the password after the initial setup by first SSHing into one of the unix machines and then running: # passwd
