Answer : All Students in ENCEi 489C/ENME 489C will be expected to have a GLUE computer account. ------------------------------------------------------------------ You can apply for one through the website http://www.helpdesk.umd.edu/faqs/unix ------------------------------------------------------------------
The Glue system operates under a "Pay-for-Print" policy. To print from a open glue lab, you will need a print account. This account can be used not only for the Glue Open labs, but also all over campus (WAM labs: PG2, Hornbake...). Each page costs $0.10. Users must obtain a Terrapin Express card in Room 1109 South Campus Dining Hall, in the hours 08:00 - 16:00. After doing this, they must get their print account activated in the Laser Print Cost Recovery (LPCR) office, Room 3326 Computer Science Center. The minimum deposit for the Terrapin Express Account is $25. Users can check their print account by telnetting to the address: bank.umd.edu The login id is "teller". The bank will then ask for the print account number and the password. The user can then move funds from the Terrapin Express account to the print account. For further help, please consult the first-aider on duty.
Answer : Dial-up access to the College of Engineering's network of UNIX computers is provided through the Computer Science Center's (CSC) annex service. All dialup lines are set for 8 bits, 1 stop bit, and no parity. The modem pools that you can access are: (a) (301) 209-0700 -- X2 56kbps modems, 3hr session limit. 40 hrs per 14 days quota limit. (b) (301) 864-2087 -- 33 kbps modems. 15 min express service session limit. 40 hrs per 14 days quota limit. Access from Baltimore (c) (410) 962-8865 -- 28.8 kbps modems, 3hr session limit. (d) (410) 962-8867 -- 28.8 kbps modems, 15 min express session limit. WAM (Workstation at Maryland) accounts are available to all University of Maryland students from the Computer Science Center Consulting Lab (CSS 1400). Bring your University ID and current registration card. To dial in, you will need to connect to the computer or terminal you are using. Run your favorite communications program and set your communications port parameters to 8 bits, 1 stop bit, and no parity. vt100 is a good choice for the terminal type if you are not sure what to use. When the connection to the annex service is established, you will see the annex prompt. Issue the following command to initiate a login session: telnet <machine>.eng.umd.edu where <machine> should be replaced by the name of the workstation that you would like to log into.
Answer : The glue system currently supports Netscape 4.7 and the UNIX version of Microsoft IE 5.
Answer : To save a file, click on the "File" item located in the top left-hand corner of the Netscape Browser. Then select the pull-down menu item that has a title "Save As..." A small window should pop-up requesting information on the location and format for the file containing the saved page. The three file formats are: Text -- Save the the text within the page. Source -- Save the html code for the page, including the text, tags etc.. Postscript -- This saves the file in Postscript format. Postscript is a special computer language understood by many printers, and is used to send text and graphics of all varieties to the printer. You can use this option to save an image of a web page as a Postscript file, which can then be sent to a Postscript printer to reproduce the file on paper.
Answer : The answer to this question will depend on the local configuration of your computer. Generally speaking you will need to give a command like qpr -q name-of-printer name-of-postscript-file.ps See the lab attendant for specific details.
Answer : Chapter 3 of Austin/Chancogne contains step-by-step instructions for compiling small C programs using the Gnu C compiler. Pay particular attention to command line arguments needed to set the filename for the program executable, and to link the program object code to the math library.
Answer : When you log into your Glue account, you are initially in your home directory. Typing: cd ../pub put you in your public directory. This is a directory that the general public has access to, and therefore this is where your home page should be stored. You should put your home page in a file Welcome.html located inside the pub directory. So if your login name is let's say "dubya", then the location of your home page will be something like /afs/ ... /dubya/pub/Welcome.html (The row of dots indicates that the file system will change from machine to machine) Folks from outside the University of Maryland will be able to view your home page using the URL http://www.glue.umd.edu/~dubya/ More Information : Follow the link to "Instructions for Creating a Personal Home Page" from the Internet Resources section of the ENCE 489C home page.
Answer : You will need to write your Home Page in the Hypertext Markup Language (HTML). An easy-to-read introduction to HTML is "A Beginners Guide to HTML," located in section two of the Class Notes.
Answer : The File Transfer Protocol (FTP) program works on the same concept as the file manager as in Windows 3.1. To transfer files: 1. Save the file onto disk. Hard or floppy. 2. Click on the window icon FTP. This icon is usually pink letters on a white background. This icon will open up the "File Transfer Protocol" program. 3. Click on the space that says profile name. You will want to be able to get into glue with your login and password. One of the set ups in the drop list will allow you to do this. 4. Fill in your login where it says user id and password where it asks. 5. Click on OK 6. You will now see a split window. on the left hand side is the computer you are on, and on the right is your computer account. In order for you to put stuff(files, etc.) into your pub account you have to open up that part of your account. Look at the right part of the screen. In the upper right you will see something that looks like .. Click on the two dots. This will take you up a level in your account. 7. Now you should see another list of things. One should be pub. This is you pub account. Click on pub. If you have started your web site you should at least see Welcome.html here. You are now in the pub part ofyour account. 8. To transfer things there you now must look at the upper left of the window. Here you will see things that resemble the computer you are on. For instance [-a-], [-c-], are both drives. [-a-] is your floppy drive and [-c-] is your hard drive. If you have things saved on a floppy click on [-a-] and then you will see all the files that are on your disk. 9. Now highlight the thing you want to transfer by clicking on it. 10. Now that it is highlighted click on the right arrow and the program will transfer that file to your school account. 11. Your done. The file should now be on the right side bottom. If it is there, then it is in your pub account.
Answer : A good starting point is: http://home.netscape.com/assist/net_sites/bg/backgrounds.html For more sites, go to a search engine and do a search on "background pattern"
Answer : If you are running netscape on a PC, then you can simply move the cursor to the background, and click on the right button. A small window will appear asking where you want the background image to be saved. Otherwise, you can retrieve a background color pattern directly from the Netscape cache (the cache stores images and patterns locally on your computer, thereby enhancing performance). The cache can be accessed by typing about:cache in the "Location" window of Netscape.
Answer : Free counters are available at: http://counters.qpt.com/
Answer : First, check your html code to make sure you haven't made a silly typo. The html should look something like: E-mail : <a href="mailto:email@example.com"><b> firstname.lastname@example.org </b></a> If your E-mail still doesn't work then perhaps your Netscape browser settings are incorrect. To check your mail preferences go to the Netscape Options menu and button on "Mail and News Preferences". Then select the services page. The SMTP (simple main transfer protocol) setting for outgoing mail should be smtp.glue.umd.edu for glue users, and smtp.isr.umd.edu for users at ISR.
Answer : You can register a domain name for your company by contacting Network Solutions Inc. See www.internic.net. I believe the fee is $100/yr. Nothing happens physically? All this means is that some nameserver in the Internet world will contain an entry for your domain and point it to some IP address. If there is a machine on the Internet with that IP address, then all packets will be forwarded there. Otherwise, nothing will happen. Do I need to purchase a server and have it on for 24 hours/day? No. There are several companies out there that can house your domain for you for a fee. However, you are free to do so if you wish. For more information, see the internic web site www.internic.net and the FAQ at http://rs.internic.net/domain-info/registration-FAQ.html
Answer : A script file contains a copy of all of the commands given at the keyboard and all of the output sent to the computer screen. The syntax for starting a script file is: prompt >> script name-of-script-file ..... now go ahead and run your programs. A copy of the commands and program output will be echoed to file "name-of-script-file" The script file is terminated by typing prompt >> exit Now send the "name-of-script-file" file to the printer.
