The EOS name is an acronym for "Exploratory Operating System." The labs were named this because we are "exploring" operating systems and software. The Architecture lab is refered to as the Arch lab. This lab is designed to study the impact of different machine architectures on computing. Both labs function the same for most computing tasks and are, therefore, collectively referred to as the EOS Lab. Top Location The EOS machines are located in 1135 MAK and are named eosXX, where XX is 01 through 24. The Arch machines are located in 1175 MAK and are named archXX, where XX is 01 through 08. Top Lab Key Cards Entry to our specialized labs require a key card. Key cards can be obtained from the School of Computing and Information Systems staff in the CIS office (2202 MAK). There is a $25 deposit required to acquire a card. The $25 is reimbursed when you return the card. The EOS card opens the 1135 and 1175 MAK lab doors; the Datacom card opens 1136 MAK. Both cards also open the MAK courtyard door. Access is granted 24/7. To use the cards simply pass the cards near the card readers (beige box near the labs doors; black box near the courtyard door). The doors will "click" indicating that the doors are unlocked. Please DO NOT place the cards in your wallet, as they contain very fine wires that break easily. The easiest way to store the card is in the back pocket of your backpack. The card reader will sense the card through the backback.

Top User IDs/Passwords Accounts are given automatically when a student takes CS163 or a 300 level or higher CIS class. User IDs are the same as the university network ID. Default passwords are emailed to the student's user@strudent.gvsu.edu email address when an account is set up. It is required that the user change their password at the first login. A user CAN NOT log in to a system using the X Window login until their password has been changed. To log in the first time, while seated in front of a station that is running X Windows, hit CTRL-F1 to get to a text terminal login, then proceed to log in and change your password. Once your password has been changed you may log in to X Windows. To get back to the X Windows login, hit CTRL-F7. Before you leave a workstation make sure ALL the login sessions (both the X Windows and other terminal logins) have been logged out!! Those that log in for the first time via ssh need only follow the instructions of changing your password. Passwords are checked periodically to make sure they are not "hackable." DO NOT use a password based on a dictionary word, name, place, etc. Use both letters and numbers; special characters (!@#$%^&*()) are even better. Users are encouraged to change their password periodically. Use the passwd command at a command prompt to change your password. Top Account Rules/Notes There is a quota on user disk space. The soft limit is 1.5GB. If a user goes over the 1.5GB limit, they are given one week to reduce their disk usage, before the system prevents any additional disk usage. The system will email a warning to the student at their user@student.gvsu.edu address if they are over the limit. A 2GB hard limit has also been set. This limit prevents the user from going over 2GB at any time. If you hit the hard limit or time has expired when you are over the soft limit, the system will not let you log in via X windows (because it writes to your directory). You must log in via a text terminal (CTRL-F1) and remove data until you are below quota. To check your quota, bring up a terminal window and enter quota. Mp3 files MAY NOT be placed anywhere on the system were they can be accessed over the network by anyone besides yourself. Users may play games on the computers, but MUST yield the computer to any user that wishes to do school work. Top Web Page We use Apache version 2.2.2 as our web server. The name of the web server is www.cis.gvsu.edu. All the modules considered "standard," as well as PHP 5.2.0, are installed. Default Web Page The default web page provides access to announcements, faculty and staff pages, class pages and other pages of interest to the school. These pages may be altered only by faculty and staff. To access the default web page use this URL: http://www.cis.gvsu.edu Personal Web Pages All EOS users can create their own web pages. Personal web pages are allowed to use any of the following web server abilities: cgi, server side includes, indexes, multiviews, links, php, perl, and .htaccess files. To create a personal web page create a public_html directory immediately under your home directory. Make sure the public_html and your home directories are searchable by everybody. Use the following command to change the permissions: chmod o+x ~ chmod o+x ~/public_html Once the public_html directory is created, place your web pages into this directory. Make sure the permissions for the web documents are readable by others. Use this command to make all the files in the public_html directory readable by others: chmod -R o+r ~/public_html To access a users web page, the address is: http://www.cis.gvsu.edu/~userid/document If the document is not included in the url (http://www.cis.gvsu.edu/~userid), then the web server will display a listing of the files in the user's public_html directory, unless a default web page has been set up. To make a default web page, name a page Welcome.html, index.html, Welcome.shtml, index.shtml, or index.php. The web server will then automatically use one of these pages when a document is not included in the url. Cgi Scripts If you wish to use cgi scripts, create a cgi-bin directory under the public_html directory, and make it searchable by others. Place all cgi scripts in this new directory and make them executable as well as readable by others. chmod o+x ~/public_html/cgi-bin chmod -R o+rx ~/public_html/cgi-bin/ The url to the cgi scripts would then be: http://www.cis.gvsu.edu/~userid/cgi-bin/scriptname If you are using php and having difficulty debugging the script, do the following to display the error on the web browser: Create a file in the directory containing your php scripts named .htaccess Change the permissions of the file to allow apache to read to it: chmod 604 path_to_file Edit the .htaccess file so that it contains: php_flag display_errors on Rerun the script by browsing to the php file with the web browser. The error will display in the web browser. Note: Users MAY NOT place mp3 files where they can be accessed from a web page. Top SSH We use open-ssh 4.5. Only ssh protocol 2 is enabled. Along with ssh, scp and sftp are also enabled. Telnet and ftp are replaced by ssh. The EOS system does not support telnet or ftp for security reasons. However, ssh is considered "secure," because none of the data transmitted over the internet is sent in clear text. All the eosXX and archX machines are running the ssh server. It is not accessible on turing (the main server), the mirror server, or the database server. The DNS names for the machines are eosXX.cis.gvsu.edu or archXX.csi.gvsu.edu. Where the XX is 01 through 24 for the eos machines, and 01 through 08 for the arch machines. For those of you using Windows® machines and wish to log in to the EOS system over the network, you must use a ssh client (putty). For copying file to/from the EOS system you need a sftp/scp client (WinScp). Those of you more familiar with ftp commands may want to use the putty sftp client. LINUX users need to have the ssh protcol installed in their machines. Refer to the man pages for usage. Part of the ssh protocol is to assure your machine is talking to the machine you intended. To facilitate this, every ssh server has a "fingerprint" associated with it. Depending on which encryption algorithm your client is using, make sure one of the fingerprints mentioned below matchs the fingerprint your ssh clients gives you BEFORE you accept them. eos01 d0:8d:f3:e3:cb:a4:30:22:b6:b5:d2:00:eb:b7:46:f8 e3:f6:97:d6:1b:0f:11:ec:09:0f:48:93:11:9b:d5:f1 eos02 90:c2:7c:4a:95:78:20:c2:af:08:1f:04:ac:23:c4:d9 a7:44:e0:98:3e:d1:a8:ef:b1:fa:09:ba:6e:96:42:22 eos03 72:c0:d3:bf:6f:ec:2a:fb:b8:a1:d9:0c:61:00:56:4c 95:87:d3:43:7f:83:3f:4b:5f:f6:2e:38:57:c9:76:d9 eos04 a7:67:0f:eb:43:d2:95:0e:fc:e0:e7:0b:45:4a:43:b0 a7:b6:2c:8e:11:73:65:c5:4e:e4:4f:0f:a9:bb:dd:09 eos05 38:df:ae:8d:8e:19:ae:7b:8a:96:2a:de:2b:f0:b1:41 19:76:e9:9f:a7:80:83:54:bf:3a:3e:af:6f:b9:d7:10 eos06 d6:63:67:62:ac:70:fd:c6:8e:c1:3a:0d:05:4f:73:b7 ca:01:b9:62:13:74:51:0a:05:d2:48:60:66:a8:b1:82 eos07 ea:21:f4:3c:83:76:0b:8b:40:4d:8e:c6:73:8a:72:b2 85:73:b4:36:cc:df:34:f8:1a:63:2d:80:39:5a:3c:25 eos08 25:67:9c:90:ce:72:34:28:b6:9c:a1:c0:2d:73:62:c5 18:27:22:d2:12:97:3a:b8:ea:db:89:24:d8:b2:a2:92 eos09 95:41:2e:61:f7:f0:d4:7b:05:be:36:0f:d7:58:88:88 c0:16:8e:1b:b1:58:52:e5:e1:0e:49:3b:0a:04:1a:a4 eos10 77:03:75:eb:d0:f5:10:4f:0f:02:fd:a6:8e:b3:19:41 46:60:fe:44:72:9b:a9:4e:66:9b:87:5b:2c:da:e6:52 eos11 b3:4d:be:8e:bf:cd:3c:eb:b2:a7:5d:1b:9b:d5:b0:79 fb:27:ae:b8:03:2e:4b:b1:cf:0c:cc:4c:ba:a3:67:84 eos12 34:83:f0:4c:68:ff:4e:ca:76:6c:a6:71:90:3b:2d:03 ff:80:c9:32:9f:b5:e6:b3:2d:d0:c2:ec:cc:b3:2e:52 eos13 14:91:bf:2d:3a:92:bf:56:2b:fb:52:13:00:01:9b:1e c9:af:81:d1:d5:bf:b2:e0:34:39:f7:41:6e:28:32:2c eos14 6e:96:ff:d4:47:0a:ee:e2:a2:c8:88:ed:a0:56:81:b4 42:e7:9d:fd:01:12:0c:0e:dc:24:2b:24:d2:cb:a6:e3 eos15 86:02:8b:9d:9c:93:7d:a5:93:1f:c3:10:9b:bf:2f:0c 50:ba:ff:90:06:a1:ec:72:b5:d0:6b:b7:24:ec:84:42 eos16 25:58:17:74:6a:42:d0:14:f1:67:19:33:50:84:40:3f 60:84:6f:33:0c:17:86:f6:38:00:b2:57:2e:a6:10:5d eos17 19:af:c4:4c:8e:95:8b:66:72:83:ed:63:c0:a4:d5:e3 c1:c1:e4:23:e6:cd:92:13:c6:63:1e:b7:5b:7e:29:10 eos18 89:e5:65:f6:89:64:76:4a:90:4a:35:93:dd:f6:a5:96 94:42:d7:0f:06:68:b9:6a:27:cc:ec:5e:3c:33:34:a6 eos19 a3:8f:52:83:39:e0:ce:64:f0:75:cc:11:69:9a:d1:2d 39:2a:74:c2:25:1a:c4:42:7c:3c:78:01:77:f1:f4:3a eos20 4b:3c:6f:99:02:2c:4c:b7:80:0f:bd:bc:7a:c4:87:5d af:24:c1:09:f6:23:8d:f1:db:26:bf:d1:45:67:4e:77 eos21 e6:a3:68:11:de:67:8a:9d:f4:d0:e3:c4:cd:01:ef:e8 d8:4c:f5:35:fc:8b:a1:47:07:c9:dc:9a:c3:ef:1f:35 eos22 84:ec:b7:35:5e:b1:99:6d:34:cc:41:fe:46:c4:49:95 32:76:65:7d:7c:3e:87:f0:60:51:5c:d9:46:f9:18:74 eos23 72:d5:6d:29:65:5c:1c:0e:00:1f:16:ed:37:df:40:c3 87:b3:dc:5d:fe:30:4f:86:43:e8:04:b8:70:fc:46:eb eos24 f8:25:6c:91:32:46:b0:fa:e8:00:10:8f:18:b4:19:22 6c:c9:3b:7b:5b:db:25:40:83:c1:0d:bd:13:ec:fe:b9 arch01 69:c7:b8:c7:b8:2e:61:6a:d8:dd:ba:01:f3:81:6a:00 b8:9a:ad:6e:28:3d:4f:28:e2:8d:53:73:89:dd:79:28 arch02 2f:3a:84:b9:61:f0:ef:44:4d:d6:49:57:ba:0e:06:ae 9b:ec:0c:86:61:8a:72:65:1b:20:66:cd:16:63:03:4f arch03 7a:69:09:89:dc:15:c2:c2:9a:1a:8c:4d:e7:28:ec:59 16:fa:87:56:fc:78:dd:b7:9b:1b:df:21:d8:4b:af:6c arch04 e8:b6:31:86:c4:7e:b3:9e:4d:4e:7f:c8:a1:bc:46:46 9d:22:c6:d3:b8:01:fa:bd:78:eb:89:04:88:16:80:71 arch05 33:6e:3d:ad:70:58:29:44:89:c3:56:3d:58:58:11:3a c7:1d:10:02:86:95:29:18:47:66:ff:88:e6:de:9e:2f arch06 26:f0:7a:53:40:e7:db:cd:3c:53:f8:4a:ba:38:a2:ab 4c:32:87:b2:02:44:7e:77:42:cf:41:08:22:47:f1:d5 arch07 d9:ad:c0:71:76:43:ef:7d:52:d0:b0:61:10:54:6b:9b 50:1e:91:36:88:59:79:38:35:a5:7d:6a:be:a9:e7:1f arch08 e3:8b:de:17:4b:f7:b4:58:5a:26:5e:c1:6a:4f:f6:c7 8a:8a:f4:35:88:b5:a4:cb:da:95:0a:8f:ed:ea:d8:d1 WARNING....If the fingerprints do not match, please let the supervisor know. If you try to reconnect to a machine and a warning is given to you, please check the above fingerprints. The fingerprint may have changed if the machine was rebuilt (or ssh updated). If the fingerprints don't match, DO NOT accept the change; contact the supervisor. Top Oracle We use Oracle 10g version 10.1.0.4 for LINUX. Oracle accounts are set up when a student enrolls in a database course, or a request is made to the supervisor. Oracle accounts are limited to 200Mb of table space. Access to Oracle can be made through a command prompt or web browser. To access Oracle from the command prompt, log in to an EOS machine and type: sqlplus userid@orcl Oracle will then ask for your password. To access Oracle through the web interface, browse to the url: http://dbserv.cis.gvsu.edu:5560/isqlplus. It will ask you for your user ID, password and connection identifier. The connection identifier is orcl. Your ID and initial password is your university network ID. Oracle will required you to change your password upon login. Oracle also implements a jdbc interface. To access Oracle from java (jdbc) you need the following code: Connection con; Class.forName ("oracle.jdbc.driver.OracleDriver"); connectString="jdbc:oracle:thin:@dbserv.cis.gvsu.edu:1521:orcl"; con=DriverManager.getConnection(connectString,"userid","userpassword"); Further information about using java to connect to Oracle is beyound the scope of this document. Oracle documentation can be found here. Top MySql We use MySql version 3.23.58 MySql accounts are given only with permission of the Supervisor, or if an instructor wants to use it for a class. Access to MySql from the command prompt is done as follows: mysql -p -h turing Enter password:password--- Your password will not be display The default password is your EOS ID plus the last four digits of your G Number. If you want to connect to the MySQL database via java, you may use one of two drivers. Class.forName("com.mysql.jdbc.Driver").newInstance(); or Class.forName("org.gjt.mm.mysql.Driver")newInstance(); After you have loaded the driver, you make the connection. For the com.mysql.jdbc.Driver driver use: connection=DriverManager.getConnection("jdbc:mysql://turing/DataBaseName", userID, password); For the org.gjt.mm.mysql.Driver driver use: connection=DriverManager.getConnection("jdbc:mysql://turing/Database?user=userid&password=password"); Top VNC If you wish to connect to the EOS GUI (graphical User Interface) from home and have a HIGH speed internet connection, do the following: For Windows® Download and install the VNC Viewer into your machine. Download and install putty. Start Putty. Enter the full name of the EOS machine to connect under "Host Name". Click "SSH" under "Protocol". Click "Tunnels" under "Connection --> SSH" in the Category tree. Enter "5900" in the "Source Port" text box in the "Port Forwarding" frame. Enter the full name of the EOS machine to contact, followed by a ":" (colon) and one of the following choices, depending on the resolution you want the GUI to use: 1280 x 1024 5900 1024 x 768 5901 800 x 600 5902 640 x 480 5903 1440 x 900 5904 1280 x 800 5905 1152x864 5906 1680x1050 5907 1920x1200 5908 1280x768 5909 1360x768 5910 Example: If you are contacting eos05 and want a resolution of 1024 x 768, then enter "eos05.cis.gvsu.edu:5901" Click the "Add" button (don't forget this step!). Click "Open" and login to the EOS machine. Minimize putty. Start the VNC Viewer. Enter "localhost". To maximize and use the entire windows screen, right click in the top window bar and select full screen. To get back, hit CTRL-ESC, right click on the VNC task bar, and deselect the full screen mode. When you log out of the EOS machine, the screen will go blank. Get out of full screen mode and close the VNC viewer. Don't forget to log out of putty, when you are done. For MAC® Download and install the VNC Viewer (Chicken of the VNC) into your machine. Launch the application "terminal," which is located in your utilities folder under the applications folder. In your terminal window you will have to set up a secure "tunnel" for the VNC connection. We do this via ssh. In your terminal window type the following: ssh -L 5900:eos-machine:display-port username@eos-machine It will prompt you for your password, enter it, and then minimize the terminal window. Display Ports (Resolution:Port): See Above step 8 above Ex: ssh -L 5900:eos04.cis.gvsu.edu:5902 johndoe@eos04.cis.gvsu.edu Now, launch "Chicken of the VNC" and type "localhost" in the server name text field and connect. When you are finished with your session, close the VNC window and quit the application (if you like). Then log out of your ssh session with the EOS machine. Top USB Flash Drive Most pocket USB Flash Drives can now be used with EOS. Just follow these simple instructions: Insert the USB drive into the USB port on the front/side of the EOS machines (If there is no usb port on the front or side of the machine please do not attempt to access the back of the machine.) Wait approx. 3-5 seconds as the OS recognizes the USB drive. Files on the USB Drive can now be accessed in the /mnt/media directory. When you are finished just unplug the USB Drive. WARNING!!! When you unplug the drive, all programs that have files open on the USB drive will be terminated! Some USB Drives will not work in the EOS Lab, as they have a strange partition table built into them. Top VPN (Virtual Private Network) The firewall on the EOS machine has been configured to allow only one ssh connection per minute from an ip address due to continued password phishing. You want to open multiple ssh sessions in a short amount of time and you are off campus, you will need to use a VPN connection to campus. The VPN connection gives your machine a GVSU IP address. With the GVSU IP address there is no limit on the number of ssh connections you are allowed. Point your browser to https://vpn.student.gvsu.edu. Login with your network user id and your GVSU password (not your eos password). Click on the "Start" button associated with "Network Connect." This will give your computer a GVSU ip address, allowing you to access GVSU resources directly. To stop the VPN, do one on the following: Click the Sign Out icon in the Network Connect status window. Select Sign Out... from the Network Connect menu. Click and hold down the mouse button on the Network Connect icon in the Dock and select Sign Out. from the pop-up menu. Top Supervisor/Steering Committee Carl Strebel is the supervisor of the EOS Labs. The supervisor is responsible for lab equipment, software and over all operation of the EOS Labs. Requests, complaints and problems should be directed to the supervisor. The Steering Committee gives direction to the supervisor for room layout, hardware purchases, software procurement and user policy. The committee is comprised of CIS faculty and staff that have an interest in the EOS Labs, the supervisor and a student representative. The student representative is a senior Computer Science student volunteer. The committee meets approximately 2 times per term. Current members are: Dr. D. Robert Adams Dr. Hans Dulimarta Dr. Ken Johnson Carl Strebel - Supervisor Dr. Greg Wolffe Open - Student Representative Top
