GENERAL IGC networks (e.g. PeaceNet, EcoNet and ConflictNet) are now accessible via the Internet, making it cheaper and easier for many academic users to login. The Internet is the world's leading inter-university network and connects thousands of academic and research institutions around the world. From the Internet you can access us for only $3/hour 24 hours a day! If you don't know if your campus is connected to the Internet, you'll have to find out. If you don't have a friend who can tell you, then it's best to contact the campus organization that manages the campus computer networks. Otherwise, you could contact the computer science department or campus computer system, and ask to speak to a computer network administrator or computer system administrator. If your campus is on the Internet but you don't have an account on a computer that's connected to the Internet, then you'll have to acquire one. The best way to find out how to do this is to find a friend who already has an account on a computer that's on the Internet, and ask them how they got it. If you don't know anyone who has an account, then you could try contacting the head of your department, or the computer science department or campus computer system, and asking to get an account on a timesharing computer that's connected to the Internet (or else asking to have your personal computer connected to an "ethernet" that's connected to the campus "backbone" network). NOTE: internet is to be used only for bona-fide educational purposes, and it is up to an individual's sponsoring institution to make sure that a user is using it for bona-fide educational purposes. One final note: Our current Internet connection is experimental and we cannot guarantee quality or availability of access at this time. We expect to have reliable Internet connectivity by the end of summer 1991.. II. LOGGING IN TO THE IGC NETWORKS THROUGH THE INTERNET - TELNET Once you have an Internet account, you'll have to learn how to log in to it. Once you can do this, then you're ready to log in to your account on the IGC Networks. To do this, run the command telnet gatekeeper.igc.org from your Internet account. If this doesn't work, contact a technical expert at your campus to get assistance. Note that if your personal computer is connected directly to an ethernet and you don't log in directly to a campus computer, then you might need to run a command on your personal computer that's called something different than 'telnet'. If you don't already have an account on IGC, and you would like to signup for an account and pay for it with a credit card, then you should type 'new' at the login: prompt, and type RETURN or ENTER at the Password: prompt. III. File Transfers - FTP There are two different ways to upload files from your personal computer to IGC, and download messages from IGC to your own system. If you're using your personal computer and a modem program (such as ProComm or RedRyder) to login to another campus computer, then you can do uploads and downloads exactly as described in the IGC manual, i.e. using one of the "normal" file transfer protocols such as ascii or kermit or xmodem. If you're not using a modem program (e.g. you're running the 'telnet' command from your personal computer, or you're using a dumb terminal that's directly connected to a campus computer), then you probably won't be able to use one of the "normal" protocols. However, you can use your computer's FTP command instead. To use your university computer's FTP command in conjunction with the IGC Networks, you need to let us know you'll be doing this. UPLOADING: At the command: Hit to enter/edit a message, or 'u' to (u)pload a file: be sure to select (u)pload. At the next prompt: Protocol: (a)scii-text (k)ermit (x)modem (y)modem (z)modem (f)tp be sure to select (f)tp. You will then see: Please use your ftp program to log in as 'anonymous', and place your file in upload/ Use your university computer's 'ftp' command to initiate a file transfer. When asked to login, be sure to login in to: igc.org or cdp.igc.org NOT into gatekeeper.igc.org. FTP will not work through 'gatekeeper'. When you login as 'anonymous', use 'guest' as a password. This puts you into a place on our computer network that allows temporary storage of uploaded files. Be sure to change directories to 'upload/' and then use the ftp command to transfer the file from your computer to ours using your loginID as the destination name of the file. Once the transfer is completed, go back to the window where you are 'telneted' into the network and hit or . This completes the ftp upload process. This also deletes your file from the 'anonymous' upload/subdirectory. You will be asked if you want to edit the uploaded file. If you say (y)es, then use the online editor's (v)iew command, you will see the contents of your file. Hitting twice from the Edit: prompt will save and send your changes. DOWNLOADING Downloading using FTP is similar to uploading-- just in reverse. You must first inform the IGC Networks that you will be performing an FTP download: >From the Mail? or Conf? prompts, select (c)apture, followed by (d)ownload. If in Conf mode, you'll be asked to identify what you want to download. You will then be asked for a protocol. Select (f)tp. You will then see: OK. Now log in to this machine with anonymous ftp, and get the file download/ As in the case with uploading, use your university computer's FTP command to log in to igc.org or cdp.igc.org (NOT gatekeeper.igc.org!) as 'anonymous' with a password of 'guest'. Change directories to \download. (If you are still logged in from a previous FTP session, and moving from \upload to \download, you may have to change directories twice: first just do a 'cd' back to the root directory;then 'cd \download'.) Use your system's FTP command to download the file to your system. On our system, the file will have as its name your login ID. You may name it as you wish on your system. NOTE: FTP downloads are not completely secure. There may be a small window of time during which someone else might be able to have access to your file. We therefore recommend you do not use FTP for secure documents.
