THE HANDY DANDY ANALOGX PROXY SERVER
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
In case you are unfamiliar with what a Proxy Server is (which is probably
unlikely, since you downloaded this), what it basically allows you to do is
share one internet connection with all the machines on your network. For
example; my main computer is the only one which has internet access, but I
have several other machines on my local network. By running the Proxy Server
on the machine that has the internet connection (my main machine), and setting
all the other machines to use a proxy, I can browse the web from them, just
like I can from the machine actually connected.
AnalogX Proxy is designed to be simple, small, and easy to use. It currently
only supports the following protocols:
HTTP (web browsers) (port 6588)
HTTPS (secure web browsers) (port 6588)
SOCKS4 (TCP proxying) (port 1080)
SOCKS4a (TCP proxying w/ DNS lookups) (port 1080)
SOCKS5 (only partial support, no UDP) (port 1080)
NNTP (usenet newsgroups) (port 119)
POP3 (receiving email) (port 110)
SMTP (sending email) (port 25)
FTP (file transfers) (port 21)
it does NOT work with ICQ, which really requires full Socks5 or a complicated
mess of UDP port mapping - but AIM and MS Messenger both work fine. Future
versions will include more protocols, but for most people this shouldn't be
a big deal.
:::Configuration:::
All configuration is done through the 'Configure' menu... When in this menu the
proxy is disabled (you'll notice the tray icon will be red), and when done, it
will automatically start back up.
:::Configuring your local network:::
In order to use this on your local network, you must be using TCP/IP as one of
the methods the machines have to talk to each other (this can be found inside
the Settings->Control Panel->Network, if you see TCP/IP, you're good to go).
If for some reason it doesn't work, ie, the other machines can't see the Proxy,
the most common problem is the IP addresses you have the network configured to.
There are only a couple that are valid to use on a local network, I would
recommend you use 10.0.0.x (where x is a number between 0 and 255 that will
be specific to each machine). Try changing the IP and then using the
Proxy again. Also, just because your machines can see each other, doesn't mean
that TCP/IP is configured properly; if you are unsure of whether or not this
is set up properly, do the following: Choose 'Run' from the start menu, and
type 'ping [IP]', so if the other machine has the IP of '10.0.0.1', you would
type 'ping 10.0.0.1'. If the machines can see each other, this will say some-
thing like 'Reply from...' blah blah blah; if they can NOT see each other, this
will say something like 'Request timed out.'
Unless you have your local IP address assigned to you, there are only three
groups of IP's that are valid for you to use on a machine that's connected to
the net (that won't collide with other machines). They are:
10.0.0.0 to 10.255.255.255 (Class A)
172.16.0.0 to 172.31.255.255 (Class B)
192.168.0.0 to 192.168.255.255 (Class C)
So make sure your LOCAL network IP's fall within one of these three ranges, or
you're more than likely going to have problems.
If you don't know your IP address, the simplest way to get it is to choose
'Run' from the system menu, and type 'winipcfg'. Make sure you do this when
you are NOT connected to the internet, otherwise you will just end up getting
your temporary internet IP address. Another method, is to go into the network
area (as outlined above), select TCP/IP, and it's in the IP Address Tab!
If you don't have TCP configured, here's what I would recommend setting your
local IP address's to; for the server, set it's IP to '10.0.0.1' and subnet
mask to '255.255.255.0'. Then, just increment the last number of the IP by
one for each remote machine; so the next machine would be IP '10.0.0.2' and
the subnet mask would remain '255.255.255.0'. Then, on the remote machine
you would configure the Internet Options (as mentioned above) to use the proxy
server IP of '10.0.0.1' at port '6588'; and you're done!
One more thing to note about the TCP configuration; once it's completed you'll
have TWO TCP configs - one that's used for your internet connection (which you
shouldn't have to change), and one that's used for communicating across your
local network (the 10.0.0.1 example). For some reason if you use Dialup
networking, and ADD another TCP/IP protocol, Windows binds it to the modem, and
there doesn't appear to be any easy way of changing this - if this happens to
you, I normally recommend removing the dialup networking configuration, then add
everything to get the local network going, then re-install the dialup networking
configuration.
:::Configuring your browser:::
If you use Internet Explorer, on each machine you want to be able to access the
proxy on, just go into the Control Panel->Internet Options, and select the tab
'Connections'. You'll see a button called 'LAN Settings', just click on it, and
you'll see the proxy settings. For most systems, all you will need to do is
check the 'Use a proxy server' box, enter the IP address of the machine the
proxy server is running on (in the example above, this would be '10.0.0.1', and
set the Port # to 6588. Select 'Ok', launch your browser, and you should be
good to go!
If you use Netscape, go to the Edit->Preferences->Category->Advanced->Proxies->
Manual->View, whew! That's a long path! Here you'll be able to input the IP
and port address mentioned in the IE config process.
:::Configuring RealAudio:::
RealAudio can be configured to work with AnalogX Proxy as well... With the G2
version (or newer), just go into Preferences and select the 'Transport' tab.
Then, select 'Use specified transport', and click on 'RTSP Settings' and 'RTA
Settings' buttons; finally, set them both to 'Use HTTP Only'. That's it! Now
RealAudio will stream via the Proxy!
:::Configuring Email:::
Configuring Email is a little trickier, so make sure you have the web browser
proxy working properly before doing this. You now have two methods, one is to
use the method described below, which can sometimes be a pain to get working,
the other is to just use Socks4 and a client that either supports it, or works
with Socksify (refer to the section below about Socks).
If you want to try the normal method, open up the 'Configure' menu, and select
'Configure Email Alias's'; you'll be presented with the email account
configuration area. Select 'Add' from the menu; this is where you will enter
in the servers you check your email from... First, you need to enter the email
address that people send messages to, like 'bob@domain.com'. Next, you need to
set the POP3 server, which is where your email program goes when it receives
email; normally this will be something along the lines of 'pop3.domain.com' or
'mail.domain.com'. Finally, you need to set the SMTP server, which is what
your emails are sent through, which in the above example could be something
like 'smtp.domain.com'. Now, it's important to note that not every service uses
two different names for the server, you might check both POP3 and SMTP from
the same server; in this case you can just leave the SMTP field blank. That's
it for the proxy! Now you have added email support for this particular user.
Now you need to set up the configuration of the email program you use; this
varies from program to program, but you need to go to wherever you enter both
the servers that the program checks. Now, instead of entering 'mail.domain.com'
or whatever your mailserver is, you'll enter the IP address of your proxy
server, such as '10.0.0.1'. It's important to note that you won't need to
change the port settings in the email program, since the proxy uses the same
ports a normal server would. Also, you will set both the SMTP, as well as the
POP3 servers to the same IP address; the proxy will make sure they get to the
correct place. Now, let's check out your configuration; try sending an email
to yourself... If everything is configured properly, they you should be good
to go!
One more thing to note about email; it will only support using a certain
username once; for example, you can't have bill@homecomputer.com and
bill@workcomputer.com; but you can have bill@homecomputer.com and sue@another.com.
In most cases this shouldn't be a problem for users, since most people have
different usernames for each account... The reason I decided to do it this way
was to make it easier to configure email programs, but there's always a minus
to each plus.
One other note about email; if you have a different login name than email name
(like you check mail by using the login name bill, but your email address is
billyg@computer.com), then you'll need to create TWO alias in the email section;
one just like normal, using billyg@computer.com, and one using the login name
in place of the email name (so bill@computer.com).
:::Configuring News:::
NNTP support is a breeze, just enter the news server you normally use in the
config menu, and then just set up your newsreader to retrieve news from the
proxy server's IP address; it's that simple!
:::Configuring FTP:::
In order to use the FTP portion of AnalogX Proxy, you must use a dedicated FTP
program, like CuteFTP (you can find all of the FTP clients for any platform on
http://www.tucows.com/), and you MUST configure it to use a Proxy/Firewall.
Also, somewhere in it's options (usually where you turn on the Proxy option),
you'll have to select one more option, and that's Proxy Type... You'll want it
to be something like this 'USER user@domain.com'; this sets the format of the
request to AnalogX Proxy so it knows what you're trying to connect to. Refer
to your specific programs docs about how to configure it, but don't email me - I
only use CuteFTP and Microsofts FTP, so I won't know how to configure yours.
Also, this will NOT work with browsers, since they do not (currently) support
proxying of FTP requests in the same manner.
Proxy also supports the use of the OPEN command, so if your FTP client can be
configured to issue 'OPEN domain.com' then the proxy will automatically route
the connection through.
:::Configuring SOCKS4:::
Socks4 is a protocol that allows other programs not specifically written to work
with a proxy to work - *VERY* cool. NEC (the main force behind Socks) has made
a program called 'SocksCap' available for free here:
http://www.socks.nec.com/reference/sockscap.htmlIt is the primary way you get non-proxy programs to work. Just install it,
configure it to point to the proxy's IP address (10.0.0.1 or whatever) at port
1080, and then set it up to work with whatever programs you normally use. Then,
when you want to use them on your proxy'd machines, you simply launch them through
this handy app, and it takes care of the rest; nice!
Socks support has been tested and is known to work with AOL, AOL Instant
Messenger, Microsoft Messenger, etc. Please don't email me asking how to get
ANY of these (or any other) programs working through Socks - I don't use any
of these. Also, please be aware that the Socks5 implementation is only partial,
it support only TCP, not UDP. This should be corrected by v5.0.
:::Configuring Proxy thru Proxy:::
This version also supports Proxy through a Proxy support, for people who are
using a provider (or another server) that you must browse through a Proxy.
AnalogX Proxy should automatically detect this, and configure itself
accordingly. Keep in mind that for this to happen you must be using the Control
Panel->Internet Options, and not the internal browser settings (as in how
Netscape works).
:::Security:::
By default the proxy binds to all TCP/IP interfaces on your computer - this is
primarily to make it easy to get running, but it also means that it will service
requests from the Internet as well. You can force Proxy to only bind to your
local IP address in the Configuration menu, at the 'Proxy Bind' option. If this
is set to 'disabled', then it will bind to all interfaces, but if a valid TCP/IP
address is entered, the proxy will ONLY bind to that - so if you enter 10.0.0.1,
and that's your server's IP address, then the proxy will only talk to machines
that connect to that IP, in other words, only your local network.
:::The Dreaded RED icon:::
If the proxy is unable to start one of it's protocols, then the icon on the
lower right (in the system tray) will be red instead of it's normal happy shade
of green. If this happens, the easiest way to track this down is to go into
the config and turn off EVERY protocol except HTTP, then exit the config and
the icon should turn green. Now, go back into the config and turn on the other
protocols one at a time (exiting the config with each one you turn on) until it
turns red again - now you've found the protocol it was unable to start.
Normally this is either FTP, POP3, or SMTP; this means that there's already a
server running on your system for one of these protocols, which could be an FTP
server, an email checker, etc. In order to use this functionality on the proxy,
you'll need to shut down whatever program is causing the problem. Another common
cause of the Red Icon is if you have changed your proxy server's IP address, and
not updated the Proxy Bind option in the configuration with the new address.
:::Configuring misc options:::
The only other option you have is to either enable or disable logging of all
the activity on the Proxy. To do this, simply right-click on the Proxy icon on
the task bar (by the clock, on the Start menu), and choose 'Logging'. If there
is a check by it, then it will log everything to a file called 'proxy.log' in
the same directory as the executable.
If you would like the Proxy program to automatically dial the net (and you're
using dialup networking (ie, a modem)), then all you need to do is turn on the
option to automatically connect to the internet in your dialup networking
control panel. When this is turned on, any time a client computer makes a
request of the proxy, and it's not connected, it will dial up. Conversely, you
can configure the inactivity timeout to automatically have windows dialup
networking hangup when to requests come in over a period of time. I don't
personally have dialup networking installed on my machine, so I can't give
you any clearer information on how to do it. AnalogX Proxy v5.0 should have
imbedded support for dialing/disconnecting after certain idle periods, to
help resolve these issues.
:::Ports ports ports! Which is which?:::
This is just to clear up one of the more common mistakes people make; when you
set up the proxy, you will use port 6588 for HTTP/HTTPS, but the rest of the
protocols are on their normal ports, which are listed above with the brief
description of each protocol.
:::Everything is set up, so how do I run it?:::
Nothing could be easier, simply doubleclick on the proxy icon, or select it from
your Windows Start Menu... If it starts up, and the icon is green (on the system
tray), then you're in business! All the machines you have configured will be
able to access the internet for as long as proxy's running.
:::What about [insert protocol/program here]? When will it support it?:::
Please please please please please don't email me asking when Proxy will support
a particular problem, or when the next release will be available - it's very
difficult to get things done when I need to answer the 1000th request for ICQ
or some other program. If you want to be kept informed of what's going on, new
releases, etc, then make sure to subscribe to the listserver at:
http://www.analogx.com/contents/listserv.htmI send out an email once a week detailing whatever is going on, plus everyone
on the list gets access to beta copies, etc.
:::Special note for Windows95 users:::
If you're running Windows95, then you need to install ALL of the updates related
to dialup networking, TCP/IP, and Winsock 1 and 2, otherwise the program will not
run properly. You can find these files on Microsoft in their OS updates section.
:::Thanks:::
I'd like to thank everyone who helped test, especially everyone on the ListServer,
who got a copy early and put it through it's paces! Extra special thanks go to
Son Huynh, Marc Gantz, and Bruce Stickley - I couldn't have done it without
everyone's help!
