It is vast, unmapped, culturally and legally ambiguous, verbally terse (unless you happen to be a court stenographDO use a password that is at least eight characters long and that has a mix of letters and numbers. The minimum length of a password should be four to six characters long. The best passwords -- the ones that are the easiest for you to rememb or that can easily be tied to you. Some good examples of BAD passwords are: your name, your relatives' names, nicknames, birthdates, license plate numbers, social security numbers (US), work ID numbers, and telephone numbers. - tch, he has your password and can start using your account at will. - DON'T use passwords that are foreign words. The hacker can get a foreign dictionary, and ... - DON'T choose a password that relates to you personally (2) a file. It is really easy for a "cracker" to find your password by encrypting every word in the dictionary, and then looking for a match between the words in his encrypted dictionary and your encrypted password. If he finds a maften you should change your password, but a good rule of thumb is to change it at least every three months. - DON'T pick a password that is found in the dictionary (1). When you set your password, it is encrypted and stored into password on a regular basis (1). There is no better way to thwart a would-be cracker than to change your password as often as possible. Your local Internet service provider will be able to tell you your system's recommendation on how os to ensure that *NO ONE* other than you can use your account. - NEVER write your password down, and especially never write your password anywhere near your computer. - NEVER e-mail your password to anyone. - DO change your ear your computer, and ... well, you get the picture. There are some KEY points you need to remember to protect yourself and your account: - NEVER give your password to *ANYONE* (1). The whole purpose of having a password in the first place ie only defense against people who want to break into your account -- a.k.a. "crackers" -- is your password. Keep your password secure, and you should never have anything to worry about. Give your password to others, or write your password down and put it nT of people out there who would LOVE to break into your account and "use your account as a base for operations (1)." How prevalent is this? According to Mike Godwin, Chief Legal Counsel for the Electronic Frontier Foundation, it's "fairly common."

Unfortunately, there are a LO er), hard to get around in, and up for grabs. Large institutions already claim to own the place, but most of the actual natives are solitary and independent, sometimes to the point of sociopathy. It is, of course, a perfect breedinger, and the ones that are the hardest for crackers to crack -- are passwords that are like those fake words you used to create when you would cram for a test. For example, to remember that "the Law of Demand is the inverse relationship between price and quantity demanded," I created the word TLODITIRBP&QD. NO ONE could hack that as a password. Best of all, its EASY to remember (well, its easy for an economist to remember). Here are a couple of other good passwords: Sentence e day that you do have TELNET access). With TELNET, the commands that you type on your keyboard are sent from your terminal to your local Internet service provider, and then from your provider to the remote computer that you have accessed. Unlike the LISTlogies. I promise to make it up to you next week when I show you File Transfer Protocol -- and besides, you can always take today's lesson and tomorrow's lesson and bug your local Internet provider into offering TELNET (you can also save this lesson for thf the public programs and services that these other computers offer. There is some bad news, though. Some of you, especially a good number of you with "level one" Internet access, do not have access to TELNET. If this is true for you, please accept my apo !"# this workshop. For the past week, we have talked about communicating on a one-to-one basis (e-mail) and on a one-to-many basis (LISTSERV and Usenet).

So what can you do with this ability to log into remote computers? If your local Internet provider allows it, it is possible for you to TELNET into your account from another city and check your e-mail while you are on vacation or away on business. You can also TELNET into huge databases to do research, oTELNET program and access the address all in one easy step? Instead of doing the two steps I just went over, you may be able to just type telnet on the command line (for example: TELNET YALEINFO.YALE.EDU 7000). After you have told TELNET whiindows or a Mac, the OPEN command may be located on a pull-down menu). If you don't include the port number, TELNET will automatically assume that you want to connect to port 23. Remember when I said that some nifty TELNET programs allow you start-up the ost won't. If your program does not automatically ask you for the address, you need to type open on the command line. For example, to get TELNET access to YALEINFO.YALE.EDU 7000, you would type OPEN YALEINFO.YALE.EDU 7000. (If you are using Wlick on the TELNET icon. The second step is to give the TELNET program the address of the computer that you want to access. This is where the programs start to differ. Some programs will automatically ask you to enter the address of the remote host, but me TELNET in Windows or on a Macintosh). Starting the TELNET program is easy. All most of you have to do is type the word TELNET on your command line, and the program will start right up. If you are using Windows or a Macintosh (or an equivalent), double-clot of different TELNET software programs around, but each of these programs operate on the same basic principles. (BTW, my explanation may be a little "mainframe-y" but you will soon discover that you can easily translate my explanation so that you can use simple step!) 3. Make a note of what the "escape character" is 4. Log in to the remote computer 5. Set the "terminal emulation" 6. Play around on the remote computer 7. Quit Now let's talk about each of these steps. There are a lain them all in a minute. But first, here are the seven steps: 1. Start-up the TELNET program 2. Give the TELNET program an address to connect to (BTW, some really nifty TELNET packages allow you to combine steps 1 and 2 into onbernet.cse.fau.edu 2010 bbhost.hq.eso.org 6969 fedworld.gov 4242 We seem to have the addresses down pat. Now for the fun stuff! There are seven steps to a successful TELNET session. These steps are all based on simple common sense, and I will expwant it to pull up. A TELNET address with a port number allows you not only to access a remote computer, but to also pull up a specific program or server on that remote computer (BTW, the standard port number is port 23): seabass.st.usm.edu 23 cyELNET addresses with numbers at the end of them. Those numbers are "port" numbers. Port numbers don't have anything to do with hardware ports on the computer; instead they are (sort of) a way for you to tell the remote computer which program or server you "user" and the "@" part. All we care about now is the stuff *after* the @. TELNET addresses look something like this: seabass.st.usm.edu cybernet.cse.fau.edu bbhost.hq.eso.org fedworld.gov Gee ... that's easy. You may also see T. Last Tuesday (in MAP04: E-MAIL), I showed you that an Internet address for a user looked something like: user@address. Well, since we are no longer interested in the person -- we want to access the computer, not the person -- we can throw away both the r even TELNET into libraries around the world to check if they have a certain book that you are looking for. TELNET also offers an easy entry into the world of Gophers and the World Wide Web for those people who may not otherwise have access to these toolsch computer you want it to access, and right before you gain access to the remote computer's login screen, you will see something like this: telnet YALEINFO.YALE.EDU 7000 Trying 130.132.21.53 Port 7000 ... Connected to YALEINFO.YALE.EDU Escape character is ... This tells you that your TELNET program is trying to access the YALEINFO.YALE.EDU 7000 address, gives the IP address for YALEINFO (remember those from MAP04?), tells you when you are connected, and gives you the escape character.te does not let you in, its probably because that site is having some problems. If this happens, just pick another site. - Please remember that your local Internet service provider only handles the *local* part of your service. Is, and the password required.

This week we are going to use a tool called "File Transfer Protocol" (or "FTP") which will allow us to access remote computers and retrieve files from these computers. Actually, it is probably more accurate to say that we will be using "anonymous" FTP, but we'll explain that in a minute. What sort of files are available through FTP? Well, "hundreds of systems connected to the Internet have file libraries, or archives, accessible to the public. Much of this consists of free or low-cost {computer} progdo not flood SURAnet. Later this "week" we will post a list of FTP sites that you can visit (much like the TELNET list we posted "Friday"). Until we post that list, just sit back and enjoy the show :) Since this lesson is already over 1 their hearts. If we take advantage of this kindness, and access various FTP sites during working hours, those FTP sites may decide to close their doors to the public ... and then EVERYONE loses. In light of what was said in #1, please ose of you who are reading this at work, and who only have Internet (and FTP access) through your employer. However, as responsible Internet citizens we have to remember that the FTP sites are providing us FTP access out of the kindness ofth on your system and on the remote system that you are accessing. Because of this, FTP sessions should only be run during non-working hours (usually 6 PM to 6 AM local). We realize that this constraint is going to be a difficult for thersity of Alabama's connection to the Internet is through SURAnet (a large regional network), so we're going to FTP to them. Before we do that, though, there are three things that we need to emphasize: FTP requires a heck of a lot of resources, boote site your password Look around the directory for files Change Directories Set the transfer mode (optional) Get the file(s) you want Quit The best way to understand what is going on is to look at a sample FTP session. The Univsic steps in an FTP session are: Start-up your FTP client Give your FTP client an address to connect to (and, just like TELNET, step one and two can be combined into one easy step). Identify yourself to the remote site Give the rem FTP clients out there do the exact same thing, they all use different commands to do it. Fortunately, if you can understand the basics of what happens during an FTP session, the commands - no matter what client you are using - are pretty easy. The ba TELNET into remote computers and run programs on those remote computers, and it also allows you to use FTP to get files from remote sites. The client/server relationship is also what makes our job as an Internet trainer quite difficult. While all of theet stuff from, distant computers. The client on your service provider's system takes your commands and turns them into requests for information from programs - "servers" - running on other, distant computers. The client/server relationship allows you toto quickly review the client/server relationship that was briefly mentioned in lesson three (MAP03: Levels of Internet Connectivity). "Client" is just another word for a program running on your service provider's system that enables you to talk to, and gnd} even summaries of every {Animaniacs} episode ever made. You can also find extensive files detailing everything you could possibly want to know about the Net itself" (1) Before we get too in-depth into FTP, we think that now is as good a time as any If you want a copy of a recent U.S. Supreme Court decision, you can {get a copy using FTP}. Copies of historical documents, from the Magna Carta to the Declaration of Independence are also yours for the asking ... You can also find song lyrics, poems, {arams for virtually every make of computer. If you want a different communications program for your IBM, or feel like playing a new game on your Amiga, you'll {probably} be able to get it {using FTP}." "But there are also libraries of documents as well. 00 lines long, we hope that you won't mind if we break this FTP lesson into two lessons. The first lesson will be "today," and we'll finish "tomorrow." This will mean that we will end this lesson in the middle of our sample FTP session, but it will also mean that this lesson won't be the size of a small book :) Starting an FTP session is pretty easy. For most of you, all you have to do to start-up your FTP client is type ftp on you system's command line (or, if you are in a Wi the client an FTP address to connect to, we've identified myself to the remote site (we told it that we are anonymous), and we've given the site our password. Now it's time to see what sort of files and directories are around, and to get those files .nd: Notice the line "Guest login ok, access restrictions apply." This means that the site has given me access, but we only have access to the files that are available to the general public. Okay ... now what? We've started-up my FTP client, we've givenave problems, 230-please try using a dash (-) as the first character of your password 230- -- this will turn off the continuation messages that may be confusing 230-your ftp client. ... 230 Guest login ok, access restrictions apply.

If you have any problems with 230-the server please mail the to systems@sura.net. If you do hyou need to use your full Internet address as your password. This helps the FTP site keep track of who has visited its site. So, since it wants our password, and since the password for any anonymous FTP session is ones full Internet address, we type out :) >>>USER anonymous 331 Guest login ok, send your complete e-mail address as password. Password: COOL! Its going to let me in. All we have to do is give the site a password. Out of politeness to the FTP site, if you login as "anonymous", of that site, but you would still like to access that FTP site, look around, and retrieve files. So, where it says USER, we type the word anonymous hit enter, and cross our fingers. If SURAnet does not allow anonymous access, we're about to find we mentioned earlier comes in :) The other way to access some FTP sites - at least those FTP sites that allow outside access - is to use the userid "anonymous". By using the name "anonymous", you are telling that FTP site that you aren't a regular usertom line is asking us to log in. If we had an account on the SURAnet system, we would enter our SURAnet user ID. But, since we don't have an account on this system, we have to find another way to access the system. ;) This is where the "anonymous" FTP EDT 1994) ready. USER (identify yourself to the host): The second line tells us that our system is connecting to ftp.sura.net (and even gives us the IP number for ftp.sura.net), the third line is some automatic information from SURAnet, and the botmit.edu, we would type "ftp lcs.mit.edu"). Once we hit the enter key, the following appears on our screen: ftp ftp.sura.net Connecting to ftp.sura.net 128.167.254.179, port 21 220 nic.sura.net FTP server (Version wu-2.4(1) Fri May 20 10:20:58 TP address is ftp.sura.net, so we would type ftp ftp.sura.net to start an FTP session. (Note that the second "ftp" is part of SURAnet's FTP address. If we wanted to ftp to info.umd.edu, we would type "ftp info.umd.edu"; if we wanted to ftp to lcs. and give your client an address to hook up to, all you would have to do it type the command ftp and replace with the address of the FTP site that you want your client software to access. In our example, the SURAnet Fndows or Mac environment, double-click on the FTP icon). From there, you would give the client an FTP address to connect to. Like TELNET, however, there is a way to combine these two steps into one, easy step. For most of you, to access your FTP client.. which we will do tomorrow :) ------------------------------------------------------------------------ Homework: See if your local Internet service provider has a handout on FTP commands.

Using the duck theory to determine if a file is an ASCII or Binary file, you can safely assume that if you have a file that looks like a ASd bet that the file is a Binary file. There are, of course, always exceptions to this rule. The "duck theory" also works pretty well in determining if a file is an ASCII or Binary file. The duck theory says that if it looks like a duck, waddles like a d .DOC; the extension for SQUIRREL.TXT is .TXT). If the file's extension is .doc or .txt, or if the file does not have an extension, it is a good bet that the file is an ASCII text file. If the file has a weird extension - like .gif or .zip - it is a gooch of information, including your transfer mode :) BTW, how can you tell if a file is an ASCII file or a Binary file? Well, take a look at the extensions (remember, an extension is the stuff at the end of the file name - the extension for CRISPEN.DOC isjust type ascii and FTP will reset its transfer mode to ASCII. If you ever forget what transfer mode you are currently using - something that we do ALL of the time - all you need to do is type status and your computer will display a whole bunde in FTP is easy. All that most of you have to do to change the FTP transfer mode from ASCII to Binary is type binary right before you get the file, and the file will be transferred to you in Binary format. To change back to ASCII transfer mode, our client's default transfer mode is ASCII and you try to retrieve a Binary file without first resetting the transfer mode, your Binary file will be transferred in ASCII and the file WILL NOT WORK once you get it. Fortunately, changing the transfer mo no universal default transfer mode for FTP clients. Some clients use ASCII as the default, and others use binary. This means that unless you tell your FTP client to do otherwise, all of your files will be transferred in the default transfer mode. If yoint presentations, satellite weather images, and sound files. Remember, ASCII files are just 'plain' text files that can be read on any computer, and Binary files are files that can only be run on certain computers or programs. Unfortunately, there is Data files must be saved in "Binary" (which is just a bunch of zeros and ones). Binary files are files that can only run on certain machines or programs. Good examples of Binary files include shareware software, Microsoft Word files, Microsoft Powerpn an ASCII text file will appear the same on any computer regardless of the computer's brand name or operating system. ASCII is fine and dandy for saving and transferring text files, but it won't work with non-text, data files - like computer programs.American Standard Code for Information Interchange, and it is the standard format for transmitting textual data. Any computer can read an ASCII text file. Without going too in-depth into how ASCII works, let's just say that ASCII ensures that the text ihings that we want to discuss. "Yesterday" we showed you how to retrieve a text file using FTP. But how can a text file written on an IBM be read on an Apple Macintosh or on a Unix workstation? Its easy - thanks to something called ASCII. ASCII is the CII text file and is seen in the same directory as other ASCII text files, you can safely assume that the file that you are looking at is, in reality, a DUCK :) (First squirrels ... now ducks ... this workshop is getting to us.) ------------------------------------------------------------------------ Multiple File Transfers: How can you transfer multiple files at the same time? Simple! Use the "mget" (multiple get) command! Let's say that we want to get every file in a particular directory with thl site will actually have SEVERAL commands in it. The basic FTPmail commands are, in order: reply This tells ftpmail where to send the file(s) to. connect This tells ftpmail the site that you want it are ready to start sending commands to the ftpmail address!

It turns out that storage space problems are not limited solely to personal computers. As the numbers of files that are available through ftp increases daily, ftp sites are actively looking for ways to squeeze more files into a limited amount of space. The ftp sites accomplish this by using file compression. The good news is that a compressed file takes up a lot less space on the ftp site's computer. The bad news is that a compressed file is absolutely useless until you uncompress it. Wait ... it er common extension for text documents.

Fortunately, most uncompression software is either public domain (meaning that it is completely free) or shareware (meaning that you can get a copy of it for free, but the author expects you to send him some money for the program if yded to uncompress the files.

Some really nice ftp sites have expanded READ.ME files that include a mention about what compression method was used and where you can get a free copy of the software neeion methods in use today :( If you have to know what compression method was used before you can uncompress a file, how are you ever going to figure out which method was used? Well, it is actually pretty easy: Most ftp directories have a READ.ME filgets worse.

If your site has its own Archie client, you should use that client instead of telnetting or e-mailing to a distant Archie se(and its filename), retrieving the file using ftp is easy! There are three ways that you can access Archie: through an Archie client running on your local Internet service provider's system, through a telnet connection directly to an Architory that the file is located in is /pub/areaii and the name of the file is roadmap.ps Archie doesn't retrieve the file for us, but it does tell us exactly where the file that we are looking for is located.

Well, this tells us the address of the anonymous ftp site is theory.lcs.mit.edu the direcing an Archie client or server a keyword to search for. A few minutes ago we did an Archie search using the keyword "roadmap". Archie sent us back a whole bunch of information in the following format: Host theory.lcs.mit.edu (18.52.0.92) approximately 2.5 million unique filenames themselves containing 200 Gigabytes (that is, 200,000,000,000 bytes) of information. The current catalog requires about 400 MB of disk storage." (1) You can search this database for file locations simply by givus ftp sites. All of the Archie servers talk to each other, and they pool their information into a huge, global database that is periodically updated. "The Archie catalog subsystem maintains a list of about 1200 Internet anonymous ftp archive sites of here all of the files that we want are located? Well, such a search program exists. It is called "Archie". Archie is actually a collection of servers.

Finally, we want to - once again - thank Osborne/McGraw Hill for giving Crispen permission to quote from "T site and try an Archie search for the file (using the file's name as the searchterm). Remember, with most FTP clients CASE COUNTS. Typing get AGRICULTURAL.LIST won't work if the file is named agricultural.list If you are using FTPes appear and disappear every second, and files are shifted around just as frequently. If you get into a site and can not find the file that you are looking for, look in the README file for a directory of files. If that fails, get out of thee to take the "scenic route" to the file (example: type "cd pub", then type "dir" to look around the pub directory. When you are done in the "pub" directory, type "cd nic", and then type "dir" to look around the "nic" directory ...) Sitot mean that that file is the only file that you can get. Use the "DIR" command often :) Just because the path address may be /pub/nic/articles, that does NOT mean that you have to go straight to that directory. You are more than welcomcommand to look around that particular directory for the file(s) that you want to get. Some other hints: The README file is your friend. Get it every time you see it! LOOK AROUND! Just because we have told you where a file is, that does n your "cd" or "chdir" command should be cd /pub/nic and your "get" command should be get agricultural.list Some listings do not list file names. These listings have a * after the last /. This means that you are going to have to use the "dir" the "Path" part isn't difficult, but there is a trick that you need to remember: everything after the last / is the file name.
