- ********************
- *** What it does ***
- ********************
-
- Socketeer is (intended to be) a stress-free way of connecting an Acorn
- machine to the internet through a telephone (or ISDN) line. I wrote it
- because there aren't any good, free, uncomplicated and reliable internet
- diallers around for RISC OS; certainly nothing to touch the ease of use of
- Windows 95's Dial-Up Networking.
-
- ************************
- *** What you'll need ***
- ************************
-
- These need to be installed on your computer for Socketeer to work:
-
- - Acorn's latest Toolbox modules (from around December '97)
- - !FreeNet or !Internet
- - The ANT / Acorn Resolver module
- - !SerialDev, the block serial drivers
- - Either Sergio Monesi's or Acorn's PPP module
- (Sergio's PPP driver will only be used if it is registered, and thus not
- subject to the 15-minute connection time)
-
- Note that the PPP, PPPdriver and Resolver modules (except for FreeNet's)
- *must* go inside the !System.Modules.310.Network folder, otherwise Socketeer
- won't find them (though you can alter this easily enough, I want to keep
- standards!).
-
- Also, make sure you have a suitable Choices folder set up-- this should be
- fine with all RISC PCs, and older machines as long as they use Acorn's !Boot
- structure.
-
- If you are lacking any of these, you ought to go to
-
- http://www.soup-kitchen.demon.co.uk/software/socketeer.html
-
- before continuing, or ask your nearest friendly PD library for the
- relevant modules (such as APDL) if you don't have internet access.
-
- ******************
- *** Setting up ***
- ******************
-
- Copy Socketeer to wherever you can find it most easily, or (like me) in your
- !Boot.Choices.Boot.Tasks folder so it loads on startup. After loading it for
- the first time, go straight to the Setup... window off the main icon, rename
- the Default setup, and enter the details of your internet connection into the
- relevant boxes. If you have accounts with more than one service provider,
- click 'Add...' and repeat the process for as many accounts as you have.
- Before clicking on 'Save changes...', make sure you've chosen the account you
- wish to use primarily.
-
- Modem
- ~~~~~
- The Modem setup is all pretty standard: the only thing you might need
- to change is the speed if your modem doesn't support 115200 baud, or if
- you've got an old computer which won't go above 19200. The 'Drop connection
- cleanly' option will mean that Socketeer trusts your PPP module to drop the
- connection rather than dropping the DTR line; I'd suggest you only use this
- if you know what it means ;-)
-
- Internet provider
- ~~~~~~~~~~~~~~~~~
- If you don't know what the internet provider settings mean, give your ISP's
- helpdesk a call, explain your situation, and they'll be able to fill in the
- fields for you. Same for your account details, though they should have sent
- you these by post. PEOPLE USING ACORN'S PPP MODULE TAKE NOTE! You'll need
- to put a PAPSecrets file inside your !Internet.files.PPP folder, of the
- format:
-
- j.smith * password
-
- (e.g. your login name, a space, then an asterisk, then a space, then your
- password, then a new line) for as many accounts as you use PAP with. Also,
- since 0.12 you *must* explicitly enter your ISP's gateway address so that the
- connection monitoring code knows your nearest 'external' internal address.
-
- PLEASE NOTE that despite appearances, the only connection types supported are
- PPP and PPP (PAP) which seems to cover 99% of commercial ISPs. I'm working
- on SLIP and the rest, honestly!
-
- Your account
- ~~~~~~~~~~~~
- This is where you put your login details: your ISP should have sent you
- these. If you don't want Socketeer keeping track of your password (which is
- stored unencrypted on your hard drive), you can ask for it to prompt you,
- either before it even dials, or it can prompt you at the moment 'when
- needed', i.e. at the moment it needs to send your password to the ISP for
- confirmation.
-
- The reason I put this second option in is for people who need to use 'key
- fobs' to generate passwords which are sometimes time-critical to within a few
- seconds. For the uninitiated, some companies are worried enough about
- security that they issue little credit-card sized 'key fobs' which generate a
- password given the current time, so that people not possessing these cannot
- possibly use the company system.
-
- Connection management
- ~~~~~~~~~~~~~~~~~~~~~
- Socketeer can be made to dial your internet provider unattended at various
- times of the day. If you specify, for instance:
-
- 0900 1200 1600-1700
-
- ...Socketeer will connect at 9am, 12pm and 4pm daily (and in this case, the
- 4pm connection will disconnect an hour later); if you do not specify a time
- for the connection to be terminated, Socketeer will use the idle time, so
- that once your mail has finished downloading, disconnection will occur within
- the time you specify.
-
- To explain: after an 'idle' period where no internet traffic has gone
- backwards or forwards, Socketeer will disconnect the modem to save on your
- phone bill. This 'idle' time also applies to connections you initiate
- yourself, in case you leave a download going then go off to make the tea like
- I do sometimes ;-) The only problem is that due to the way that Socketeer
- monitors the status of your connection, there is always some residual 'ping'
- traffic going backwards and forwards, so it also asks you to set an idle
- threshold, i.e. the maximum amount of traffic that Socketeer can count as
- 'idle'. See the statistics section later for more on this.
-
- Specifying a disconnection time like that is useful if you want to be able to
- telnet into your Demon (or other fixed IP) account while away for the day.
-
- 'Retry dead connections' specifies the number of times Socketeer will retry a
- connection if the packet driver dies prematurely, that is to say if the modem
- has successfully made a connection and BT has debited 5p from your phone
- bill. If a connection was started automatically, the redial will happen
- immediately; if you initiated the connection, you'll be asked.
-
- The online and offline scripts are files or applications which will be run
- when Socketeer connects or disconnects-- note that the offline script will
- not be run if Socketeer doesn't successfully get online.
-
- DISCLAIMER: Please note that although I have tested these features to the
- best of my ability, you use them at your own risk and I will not be held
- responsible for connections which have stayed open all day, either by
- misconfiguration or bugs in the software. Having said this, I entrust
- Socketeer to check my mail while I'm out or asleep, so if it happens to you,
- divine justice will mean it'll probably happen to me at some point.
-
- Front-end
- ~~~~~~~~~
- Here are three miscellaneous options which are largely a matter of taste:
-
- 'No sound effects' turns off the audible warnings Socketeer gives when the
- connection is faltering, or when it is about to idle out.
-
- 'Confirm disconnections' will ask you to confirm your actions every time you
- ask Socketeer to disconnect.
-
- 'Right hand button open stats' changes the default action of the right-hand
- button on the icon-bar. Normally it acts as a short-cut to connect and
- disconnect you from the internet, but you may want it to open the Statistics
- window instead.
-
- Launcher
- ~~~~~~~~
- Click the 'Launcher...' button to edit the application launcher
- configuration: this is still a bit raw, since you'll have to edit a text file
- which simply contains lines of the following format:
-
- <application path><TAB><sprite to use><TAB><text to display underneath>
-
- e.g. mine reads (verbatim):
-
- ADFS::Buttercup.$.Internet.Clients.!Fresco !fresco Fresco
- ADFS::Buttercup.$.Internet.Clients.!Talker !talker Talker
- ADFS::Buttercup.$.Internet.Newsbase.!Messenger !messenger Messenger
- ADFS::Buttercup.$.Internet.Clients.!ANTterm !antterm Terminal
- ADFS::Buttercup.$.Internet.Clients.!FTPclient !ftpclient FTP
- ADFS::Buttercup.$.Internet.Clients.Tools.!Ping !ping Ping
- ADFS::Buttercup.$.Internet.!Attacher !attacher Attacher
- ADFS::Buttercup.$.Internet directory Open Internet folder
-
- and the file format is pretty strict: you should only put one tab inbetween
- each field, and make sure the last entry has a newline after it, otherwise
- Bad Things will happen.
-
- Technical note: Each item will be Filer_Booted when Socketeer starts up, and
- Filer_Run when double-clicked on to minimise Socketeer's involvement with the
- relevant applications. Hence ou can hold down shift while double-clicking to
- open application folders too.
-
- **************
- *** In use ***
- **************
-
- Once you have chosen a setup, Socketeer will connect and disconnect when you
- tell it to: clicking the right-hand button on the main icon mirrors the
- functionality of the menu option and the big button in the main window.
- Also, Socketeer will notice if the PPP module disconnects for some reason,
- though it won't always be able to help you diagnose why.
-
- If your connection is within the 'idle' threshold you specified in the setup
- window, you'll see Zs appear on the icon. If you're seeing these Zs when
- your connection *isn't* idle, or you're not seeing them when it *is*, you
- need to adjust your setup slightly; see under 'statistics'.
-
- If Socketeer detects that the connection is faltering, a white exclamation
- mark will appear on the icon-bar. After a little more time (usually
- about 10secs), when Socketeer is convinced something is amiss, a visual and
- audible warning will appear. After a little longer, Socketeer will assume
- the connection is stuffed, and disconnect. See below for more detail on
- this.
-
- Every time you connect or disconnect from the internet, Socketeer will write
- the time and date to its log file, which you can analyse later by clicking on
- 'Call log...' from the main menu.
-
- *****************************
- *** Statistics and idling ***
- *****************************
-
- You can open the statistics window by choosing it from the icon-bar menu, or,
- if you've ticked the appropriate box in the Front-end section of the Setup,
- you can click adjust on the icon-bar icon. The first and most obvious thing
- it shows is the CONNECT speed reported by the modem; this ought to reflect
- the baud rate at which you have connected to your ISP, though it can change
- midway and you wouldn't know anything about it.
-
- Also, while online, Socketeer will regularly 'ping' your ISP's gateway
- address (i.e. the nearest machine to you on the internet) to check that the
- modem and your internet provider are still responding properly. A ping is so
- called because it expects a response from the address that it pings, a little
- like sonar. If Socketeer doesn't get a response within 2 seconds, it counts
- this towards your connection's 'Latency'-- this indicator will slowly
- increase if your connection is unreliable, and will disconnect after 20 pings
- have not been responded to. The Latency indication is only worth paying
- attention to if you suspect something is wrong with your connection: to gauge
- the actual speed, have a look at the 'Traffic' bar which will tell you how
- much data is being passed through your modem. Note that the exclaimation
- mark apeears on the icon bar after 2 lost pings, and the audible warning
- after 10.
-
- Socketeer decides whether your connection is 'idle' by looking at the traffic
- bar every half-second and comparing it against the idle threshold in the
- current setup. When idle, you'll see Zs appear on the icon bar. To
- calibrate your idle threshold (and I apologise for this unsatisfactory way of
- doing things), connect Socketeer to your ISP and watch the traffic indicator:
- it will most likely flicker between zero and a lowish reading. Your idle
- threshold should be set a bit above this; don't worry if the reading jumps up
- occasionally as Socketeer will ignore uncharacteristics 'blips' in the
- traffic. No, I don't know why it does it either ;-)
-
- ********************
- *** Other issues ***
- ********************
-
- Some may find it worrying that Socketeer doesn't use any scripting: I decided
- not to go for event a simple script language because 99% of ISPs I've
- encountered ask users to login in exactly the same ways. What it does is to
- read a list of prompts and responses to expect from the server; this file is
- called Prompts, and is stored in '!Socketeer.Bits'. If you find Socketeer
- can't log you in, it's probably because your ISP's prompts are not stored in
- this file: please mail me any useful additions to this (Technical
- note: ESPECIALLY if you find Socketeer can't cope in a particular situation,
- or you've had to bodge something which ought to be included in the
- front-end).
