How To Access Login Servers

The remote login servers can be accessed through a Secure Shell (SSH). SFTP is available for encrypted file transfers on port 22. FTP is disabled on the login servers for security reasons.

If you are trying to SSH over windows, putty is a very popular and powerful tool available here. When you run putty, under the Category section, select Session if it isn't already by default. Click the SSH button, enter the hostname css"XX".cs.wmich.edu("XX" is 01-10 whichever login server you'd like to go to) and ensure that it is connecting on port 22. You can enter a name for the host below and click 'save' so that it's easier to access the next time you connect. Click 'open' to initiate the session to the login server. Accept the Server host key, then enter your username and password when it is prompted in the terminal window. If you have never worked on a unix terminal in the past, this is a good guide to get you started with all of the basic commands.

Typing 'ls' will give you a listing of all the files and folders in your home directory. A 'www' directory can be created in your home directory(mkdir www) if you wish to create a student web page, it is accessible via www.cs.wmich.edu/~username

If you are trying to access the servers from a Linux distribution, SSH is most likely already installed on your system. Open a terminal window and type "ssh username@css"XX".cs.wmich.edu", type 'yes' to accept the server key, and enter your password when it prompts you.

If you have forgotten your username or password, we can reset it for you in C-218 (On the left side of the room). Please bring your Bronco Card or Driver's License so that we can assure that we change the password for the correct username.

Note: If one of our hosts is not accepting your SSH connection, it is possible that it is down. We appreciate if you can send us an email at sysadmin@cs.wmich.edu to inform us about it before trying another login server, this helps us serve your needs more efficiently. Our server status page can be accessed here.

Accessing Login Servers on a Windows Machine

Double Click on the Putty Executable



Type in 'cssXX.cs.wmich.edu into the Hostname box. (Note that XX can be replaced with 01-10, one for each login server



Allow the security alert



Authenticate yourself to your shell account with your CS Username and password

Changing Your Password

Log in, as described above.

From the command prompt, run the 'kpasswd' command (without the quotes).

You will be prompted for your current password, and then your new password twice.

Password changes are effective immediately. You will need to update any stored passwords in Putty, SFTP clients, or other software.

Accessing Oracle

Oracle can only be accessed from machines csa01 - csa04

Use the sqlplus command to login

sqlplus

You will be prompted for your oracle pasword

SCP/SFTP (File Transfer)

SCP is a secure and fast way to transfer files between the department server and your home computer.

To put a file onto your home directory, from your desktop, type "scp /path/to/file.ext username@css02.cs.wmich.edu:~/file.ext". When prompted, enter your password, and the file you defined is now on your home directory.

If you want to retrieve a file using scp, you use the same syntax, but reversed. So for the same file, but going in the other direction, the syntax would be "scp username@css02.cs.wmich.edu:~/file.ext /path/where/you/want/the/file.ext"

Two popular clients for SFTP are WinSCP and Filezilla If you are running linux, scp is most-likely already built into your operating system, and is easy to use while not requiring that you depend on a GUI.

Email Access

CS Students no longer receive a separate CS email account. All email communications will be sent to your Bronco email (buster.bronco@wmich.edu, for example).

Any users with previously existing CS email addresses will receive all inbound email in their Bronco email account. Mail stored on the CS mail server will be available for several months over the channels listed below. A procedure for moving mail to your Bronco email account from the CS mail server will be available soon.

POP3 can be accessed via mail.cs.wmich.edu on port 995 over SSL

IMAP can be accessed via imap.cs.wmich.edu on port 993 over SSL.

SMTP is provided by OIT via smtp.wmich.edu on port 25 over SSL (use your Bronco NetID and password)

If you are connected to an SSH session, pine is installed on our CSS login servers. Simply type 'pine' into your terminal to access the text-based mail client.

Caution: Do not access mail server using both IMAP and POP3 or your inbox will potentially be corrupted.

Shell Config Files

Both Tcsh and Bash shells are available for use on our machines. Just type 'tcsh' or 'bash' to switch between shells.

Tcsh Config File .cshrc

Bash Config File .bash_profile

Directory Permissions

UNIX permissions can be broken down into 3 seperate parts, and are kept track of with a base8 numbering system. (Hope you paid attention in ECE250 and CS2300!)

There are three different permissions, spread among three different classifications of users. The first three characters refer to the rights the owner has to the file, the second three characters refer to the rights that users in the file's group have to the file, and lastly the third three characters refer to the rights that all other users on the system have to it.ur

A file permission of 715 would look like: rwx--xr-x. As you can see, the three sections are counted individually with base8 in order to come up with our final decimal permission of 715. This perticular permission would give the owner of the file full access, anyone in the file's group would be able to execute the file, while any other user is able to read and execute the file.

Permissions are represented as follows:

Read - 4

Write - 2

Execute - 1

Recommended permissions on your CS files are as follows:

Home directory rwx-----x (chmod 701)

www directory rwx---r-x (chmod 705)

Personal Web Pages

Create a directory called www ("mkdir ~/www") in your home directory. All files in that directory with global read permissions will be displayed on http://www.cs.wmich.edu/~youruserID (e.g. http://www.cs.wmich.edu/~sysadmin)

Secure Web access

Place a .htaccess file in the www directory

Microsoft MSDNAA ELMS

Students can log in to the MSDNAA ELMS website at http://msdn02.e-academy.com/wmich_cs

Your ID is your ENTIRE Bronco email address (buster.bronco@wmich.edu)

Your ELMS password will have been emailed to your Bronco email upon account creation
