- Quit Introduction to NOS & Demon Internet
- ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
- Overview
- ~~~~~~~~
- The Install_DIS package combines an internet networking program
- (AmigaNOS) an off-line mail reader (AmigaELM) and an off-line
- news reader (TIN).
-
- This provides you with the following services:
-
- * Send and receive E-Mail to and from multiple mail addresses
- * A read/write newsfeed to the 7000+ USENET newsgroups
- * FTP access to 1000's of free ftp servers
- * Telnet remote logins
-
- When You Connect
- ~~~~~~~~~~~~~~~~
- When you click on the "Connect" icon Amiganos will attempt
- to dial out to Demon and setup a SLIP connection. You can
- see some of the disl scrip negotiations in the status window.
-
- Whenever you connect to Demon Internet a number of background
- tasks start up automatically. Some of these receive new mail
- messages for your site and transmit any mail postings you have
- made across onto the internet. Other processes collect new
- news postings from the Demon News server and pass any news
- postings onto USENET. All these processes can be seen runnung
- in the status window at the foot of the main command window.
-
- The Command Window
- ~~~~~~~~~~~~~~~~~~
- The main command window is a command line interface (the net>
- prompt) at which you can enter a number of commands. Some
- of these command (ftp, telnet, ping) will start up new windows
- calles sessions. You can have many sessions running at the same
- time all shareing bandwidth on your modem line, but unlike
- true Amiga windows you can not use the mouse to swap between
- sessions. Instead use the HELP key to return to the
- command window (session 0) and from here type "session n" where
- n if the session you wish to become active. (HINT: return
- always takes you to the previous session).
-
- Some usefull commande:
-
- ping - Send a small packet of data to an internet address
- ftp - Start an FTP session for file transfer.
- telnet - Logfon to remote computer
- finger - Get information about a site or user
- session - Print list of current sessions or change session
- socet - Print list of active sockets (IP connections)
- exit - Abort all connections and hang up
- autoexit- Set the autoexit mode ie exit when all connections
- closed.
-
- Testing your Connection - Ping
- ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
- To confirm that you connection is working lets try connecting
- to a machine across the internet. The "ping" command sends
- a small data packet from you computer to another computer
- on the internet and waits for a reply.
-
- Example: Type "ping gate.demon.co.uk"
-
- You computer will try to resolve the name "gate.demon.co.uk"
- into an IP number (eg 158.152.1.65) and then set out a data
- packet. If all goes ok then you should se a reply like
-
- 158.152.1.65 2 rtt 1600
-
- Gate is a machine in the London office of Demon Internet,
- you might wat to try news.demon.co.uk (the news server that
- you will be downloading USENET articals from), or
- doc.is.ac.uk (a comuter which runs and archie server - more
- on this later) and word.std.com a computer in the USA.
-
- Transfering Files (FTP)
- ~~~~~~~~~~~~~~~~~~~~~~~
- Files are transfered around the internet vie FTP (File
- transfer protocol). There are a vast number of ftp servers
- on the internet which contain a huge number of files that may
- be transfered for free - directly to you local hard disk.
- Here is an example of how to connect to demons own ftp
- server called ftp.demon.co.uk
-
- ftp ftp.demon.co.uk
-
- This will start up a new session and connect you to the ftp
- server. All ftp sites will ask you to log in. As you will
- not have a personal account on the server you can log on
- as "ftp". At the password prompt enter your full E-Mail
- address. For example if you name is "fred" and you nodename
- is "eggbox" then your mail address would be
- "fred@eggbox.demon.co.uk"
-
- At this point you will be presented with an "ftp>" prompt.
- Some usefull commands that can be entered here are
-
- dir lists files in current directory, and will allow
- filename pattern matching. eg dir *.txt will
- show all files ending with the .txt suffix.
- Remember most of the ftp servers will be unix
- machines so that filenames are case sesative.
-
- cd Change doirectory. eg cd pub/amiga will change
- from the current directory to a public amiga
- directory.(NOTE: / not \) "cd .." will move
- back one level of directory.
-
- pwd Print working directory. Handt if you get lost
- and the ftp prompt does not show you where you are!
-
- bin Change to binary mode. If the files you are about
- to transfer are not just plain text then you must
- set the transfer mode before getting the file Some
- ftp servers will set the mode for you - but if they
- don't then the transferd file will be no good to you.
- get Get a file eg "get modem.txt" will send the file from
- the ftp server to your DIS:AmigaNOS/SLIP/Spool/Downloads
- directry. "get file_name new_file_name will transfer
- "file_name" but call it "new_file_name" when it arrives
- on your computer.
- mget Multiple file get. As above but will accept patten
- matching, using unix style patternds eg "get *.txt"
- will retreive all .txt files. You can also pass
- a lst of files eg "mget file1 file2 file3"
- quit To end an ftp session.
-
- Most ftp servers have read-me files and files which contain
- list and descriptions of files contained on the server. For
- example on ftp.luth.se in directory /pub/amiga is a file
- LONG which hols a list of all the Amiga files held on this
- site in Switzeland
-
- Example: to transfer the file Demon.txt from ftp.demon.co.uk
- words in quotes are commands that have been entered.
-
- "ftp ftp.demon.co.uk"
- 331 Guest login ok, send ident as password.
- Password: "?????"
- 230 Guest login ok, access restrictions apply.
- ftp> "cd /pub/doc"
- 250 CWD command successful.
- ftp> "dir *.txt"
- 200 PORT command successful.
- 150 Opening ASCII mode data connection for /bin/ls (0 bytes).

- 226 Transfer complete.
- ftp> "get problem.txt"
- 200 Type set to I.
- 200 PORT command successful.
- 150 Opening BINARY mode data connection for problem.txt (1369 bytes).
- : Bytes Received 216 432 648 864 1080 1296
- Get complete: 1369 bytes in 0 sec (1381/sec)
- 226 Transfer complete.
- ftp> "quit"
- 221 Goodbye.
- FTP session 1 closed: EOF
- Hit enter to continue
-
- HINT: When lsting directories they will scroll past on the screen
- and you may not be able to read them. To record the the contects of
- and session use the "record file" command from the command screen.
- Example: Connect to the ftp server first.
- Press HELP to return to the command screen
- Enter "record files.txt"
- ftp ftp press RETURN to return to the ftp session
- Enter "dir"
- all output will then be recorded in the file files.txt in the
- DIS:AmigaNOS/SLIP/Spool/Downloads directory. Use "Record off"
- from the command scren to disable this function.
-
- Telnet - Remote login
- ~~~~~~~~~~~~~~~~~~~~~
- This allows you to login and run programs on any computer on
- the internet (providing the remote system allows entry)
-
- Example: To run the "archie" file search program on the doc.ic
- computer.
-
- net> "telnet doc.ic.ac.uk"
- Login: "archie"
- archie
- # Bunyip Information Systems, 1993
- # Terminal type set to `network 24 80'.
- # `erase' character is `^?'.
- # `search' (type string) has the value `sub'.
- archie.doc.ic.ac.uk> help
- <list of help cpmmands>
- archie.doc.ic.ac.uk> "find reqtools*"
- # Search type: sub.
- # Your queue position: 1
- working... <list of ftp sites, directories and files>
- 232 matches were found.
-
- Finger
- ~~~~~~
- The finger command allows you to find out information about
- users at a site. Example
-
- finger fred@eggbox.demon.co.uk
-
- will give info on fred, where as
-
- finger @gate.demon.co.uk
-
- will give a list of users logged onto gate.
- A usefull command is
-
- finger yoursite@post.demon.co.uk
-
- which will give you a list of all mail waiting to be transfered
- to your machine.
-
- To be continued....
