Please Note: I accepted a job with Credit Suisse Group (Group Risk Management) and will be moving back to Europe. Because of this relocation (first to Switzerland, then to the U.K.) I can only offer reduced support for DynamIP. Please try peer support in the DynamIP Discussion Group if you don't get a timely response to your e-mail inquiry.


Setup

Setting up DynamIP is relatively easy. While you can fiddle around with most of the settings until DynamIP does exactly what you want it to do, it is probably a good idea to keep some of the default settings unless you are an experienced user... If you are a first-time user you should probably have a look at QuickSetup.

Options

Startup Window State Normal
DynamIP starts with a normal size window. DynamIP remembers the last position before it was shut down and will restore the main window in the same place.

Minimized/Tray
DynamIP starts either minimized (if AutoTray is unchecked) or directly in the Tray (if AutoTray is checked).
AutoTray If AutoTray is checked DynamIP will automatically start in the Tray (if Minimized/Tray is selected) and put itself into the Tray whenever the ONline event occurs (only if IPchat is off). Note that the AutoTray setting is ignored under Windows NT3.x because there is no tray.
Play Sound Files DynamIP plays sound files when notification events occur (sound files must be defined in the appropriate location, e.g. IPchat).
Notification Window DynamIP brings up a notification window when notification events occur. This is helpful if you don't have a sound card.
Background Color Color used to paint the background of the main DynamIP window. Note that all the other color settings of DynamIP are taken from the registry; you can change them from the Control Panel [Icon Display].
Foreground Color Color of fonts in the main DynamIP window. Note that all the other color settings of DynamIP are taken from the registry; you can change them from the Control Panel [Icon Display].
LOG Connection If checked DynamIP will write all Connection activities to the log file
LOG Mail If checked DynamIP will write all Mail activities to the log file.
LOG Time If checked DynamIP will write all Time activities to the log file.
LOG IP/WEBchat If checked DynamIP will write all chat activities to the log file.
LOG HTTPscan If checked DynamIP will write all server scan activities to the log file.
LOG raw UDP Packets If checked DynamIP will write all UDP packets that come in at the chat port to the log file. I use this mainly for debugging purposes...
Reset LOG file at Startup If checked DynamIP will delete the log file each time you start DynamIP; this prevents your log file from filling up your harddrive...
IE4 Internet Shortcuts If checked DynamIP will use the extended format for Internet Shortcuts (adds extra information like Accessed and Modified to Internet Shortcuts). Unless you have IE4 installed this setting won't matter.

DUN/RAS

Connection Verification Interval Interval (in seconds) between consecutive connection checks. Obviously, the smaller this value, the faster DynamIP will be aware of lost or newly established connections (on the other hand, smaller values increase the load on your system). The value must be between 5 and 60.
Keep Alive If Keep Alive is checked DynamIP will connect to the NTP server specified in the Time Tab roughly every 2 minutes (DynamIP won't set your PC clock, it will just connect to the NTP server in order to generate some traffic). This is useful if your ISP disconnects you unless there is some traffic.
IP Method Choose one of the following three methods:
  • Dynamic IP Address (Winsock)
    DynamIP tries to resolve your local host name and assumes that you're online whenever the resulting IP address is different from 127.0.0.1. This is the default method and it should work on most systems. If DynamIP does not start properly with this method (e.g. if the DynamIP window does not show up within a few seconds after starting) you might want to try the (RAS) method.
  • Dynamic IP Address (RAS)
    DynamIP checks whether you have active RAS connections going and assumes that you're online whenever it finds such connections. This method should work if you're on a LAN (w/ static IP) and have a dial-up connection going every now and then.
  • Static IP Address
    Use this option if you're on a LAN and your IP address never changes (you're basically always online...). You can also use this option to force DynamIP to a particular IP address if neither of the two above methods works on your system.
Static IP Enter your static IP address here if you select the IP Method "Static IP Address"; this field is disabled/ignored otherwise.
Connect Sound Check this box if you want DynamIP to play a sound file whenever the Connect Event occurs. You can choose any WAV file you like. Clicking on the button "Connect Sound" will play the sound so that you can test your settings.
Dial at Startup Check this box if you want DynamIP to establish a RAS connection whenever you start DynamIP.
Show Dial Progress Check this box if you want DynamIP to open up the progress window each time the RAS dialer gets activated (a side effect is that DynamIP becomes the active application). If this box is unchecked DynamIP will dial in the background.
Dial with Timer Check this box if you want DynamIP to automatically connect/disconnect at certain times. Note that you must define the times to connect/disconnect in the tab Time.
Disconnect on Exit Check this box if you want DynamIP to disconnect all your RAS connections whenever you exit DynamIP.
#1, #2, and #3 Check the box to activate the particular entry and then choose the Dial-Up connection you want DynamIP to use when establishing a RAS connection. If unchecked, DynamIP will not use the particular entry even if it is a valid one.

With Win95 you can also choose "_Windows95 InternetProfile" which allows you to set your options from the Icon "Internet" in the Control Panel).

If your ISP (= Internet Service Provider) has multiple phone numbers (or you have multiple ISPs) you can define a Dial-Up connection for each phone number (or ISP). This way DynamIP will behave as follows: it will first try to establish a connection using your first active entry, and if this fails, DynamIP will try your next active entry until a connection can be established.
Move connected entry to top of list Check this box if you want DynamIP to automatically move the last connected entry to the top of the list. This way your "bad" connections will move to the bottom of the list and DynamIP won't waste time trying to establish a connection that won't go through anyway.
Hide "Connect to" Window DynamIP can hide the annoying "Connected to ..." window. Simply check the box and enter the name of the window in the appropriate field (the name depends obviously on the language version of your Windows95; the US version requires an entry of Connected to* where the star "*" is a place holder for any sequence of characters...).
Warning on unexpected Disconnect Check this box if you want DynamIP to issue a warning (sound notification) if your connection breaks unexpectedly.
Name of "Reconnect" Window If a connection is lost unexpectedly, DynamIP can click a button for you so that the dialer kicks in or the "Reconnect" window gets properly closed. The default value is Reestablish Connection. You can use the star "*" as a placeholder for an arbitrary sequence of characters.
Name of Button to push Check this option to activate DynamIP's reconnection handler. You can then select the button you want DynamIP to click whenever a connection is lost and the "Reconnect" window pops up. The default value is Reconnect... which will cause DynamIP to automatically redial and reestablish the connection. You can use the star "*" as a placeholder for an arbitrary sequence of characters. Use the ampersand "&" if the button has underlined characters in its name (e.g. Connect would be specified as &Connect).

Important Note:
If you checked "Dial with Timer" you should enter the value Cancel into the field "Name of Button to push" in Tab DUN/RAS (which will close the Win95 lost connection dialog) because DynamIP is already set to reestablish your connection.

Launch

Active Check this box if you want to enable the program launcher.
Application to launch Check this box if you want to activate this particular entry (you can define up to 5 applications and you can enable/disable them all individually with this check box). You can either use the file dialog button to select your application or simply enter the path and name of it. The above screen shot shows you how to launch "rasmon.exe" (the Windows NT4 Dial-Up Networking Monitor).

The following 2 methods are the most useful ones to launch an application:

  1. point to an executable (EXE file)
    This method works fine with all those applications that don't expect any command line parameters (e.g. the Windows NT4 Dial-Up Networking Monitor)..
  2. point to a shortcut file (LNK file)
    Use this method for all applications that need additional parameters like command line parameters, startup directory, etc. If you already have an entry in your Start Menu that launches the application correctly you might just want to point to that LNK file, e.g. C:\Windows\Start Menu\Programs\...\*.lnk.
Title of Main Window

Enter the title of the main window of the application (as displayed when it is running). You can use the star "*" as a placeholder for an arbitrary sequence of characters. This information is absolutely needed for 2 purposes:

  1. To avoid launching the application when it is already running (if you really want to launch multiple instances you can check the box "Allow Multiple Instances")..
  2. To close the application when a Close Event occurs.
Launch Events

DynamIP can launch applications on occurrence of any of the following events:

  1. Startup
    The application is launched whenever you start DynamIP.
  2. Exit
    The application is launched whenever you exit DynamIP.
  3. Connect
    The application is launched whenever a new connection is established. Note that the application is launched     after the connection is established.
  4. Disconnect
    The application is launched whenever a connection goes down (this includes manual and scheduled disconnects as well as unexpected disconnects). Note that the application is launched     after the connection is terminated.

You can click on the button "Launch Events" to launch your application (e.g. to test your inputs). Note that you might have to click the button "Apply" first to save your changes to the INI file.
Close Events DynamIP can close applications on occurrence of any of the following events: Startup, Exit, Connect, and Disconnect (see above for an explanation). Note that this functionality requires correct information in the field "Title of Main Window" to work properly.
Launch Mode Choose the startup mode of your application. Note that not all applications support this feature, i.e. some applications start in normal mode regardless of this setting.
Allow Multiple Instances Check this box if you want DynamIP to launch the application even if another instance is already active. Note that some applications do not support multiple instances, i.e. you will only have 1 copy of your application running at any time even if you check this box.

Time

Active Check this box if you want to enable the PC Clock Synchronizer.
NTP Server Name (or IP address) of an NTP server. DynamIP uses "ntp.cc.utexas.edu" as the default server, but that does obviously only make sense for users in the US (users in Europe might try "swisstime.ethz.ch"). Lists of public NTP servers are available at http://tycho.usno.navy.mil/clocks1.html and http://tycho.usno.navy.mil/clocks2.html. Please be considerate and use only those NTP servers that are "open access".
UTC offset of my location The UTC offset is simply the time difference between UTC and your location (in minutes). For example, if your time zone is PDT (summer in Palo Alto!) then the correct entry is "420" (without the quotes). Unless you are on Windows NT3.x (the registry time zone setting does not work properly) you probably want to get the offset automatically from your registry (see option "Use Registry Time Zone Information").
Timeout DynamIP aborts the connecting process if the operation is not completed within the user-defined interval.
Use Registry Time Zone Information Check this box if you want DynamIP to get the UTC offset directly from your registry (the manually entered offset in the field "UTC offset of my location" is then disregarded). This does no work with Windows NT3.x.
Synchronize PC Clock on Connect event. Check this box if you want DynamIP to synchronize your PC clock with the NTP server as soon as a Internet connection is established.
Synchronize PC Clock on ONline event Check this box if you want DynamIP to synchronize your PC clock with the NTP server whenever the ONline event occurs.
DialTimerON Enter the time you want DynamIP to establish a connection automatically (note that you must check the box "Dial with Timer" in Tab DUN/RAS for this to work). All times are diplayed in 24 hour format.
DialTimerOFF Enter the time you want DynamIP to disconnect automatically (note that you must check the box "Dial with Timer" in Tab DUN/RAS for this to work). All times are diplayed in 24 hour format (although you can enter them in any time format)..

The above screen shot shows the following example:
- DynamIP establishes a connection at 02:15 (that is 2.15am)
- DynamIP disconnects at 14:25 (that is 2.25pm)
If the connection is lost at any time between 2.15am and 2.25pm DynamIP will automatically reestablish the connection (assuming "Dial with Timer" in Tab DUN/RAS is checked!)..

Important Note:
If you checked "Dial On Demand" and/or "Dial with Timer" you should enter the value Cancel into the field "Name of Button to push" in Tab DUN/RAS (which will close the Win95 lost connection dialog) because DynamIP is already set to reestablish your connection.
Ignore DialTimerOFF if missed by more than 5 min Check this box if you don't want DynamIP to disconnect active connections unless the current time is no more than 5 minutes past an active DialTimerOFF setting. This is useful if you have "Dial with Timer" in Tab DUN/RAS checked and want to establish (or keep alive) a connection outside of any of the intervals specified with DialTimerON and DialTimerOFF. For example, assume DynamIP is set to automatically connect at 2.15am and disconnect at 2.25pm (DialTimerON = 02:15 and DialTimerOFF = 14:25). If the box "Dial with Timer" in Tab DUN/RAS is checked, DynamIP would basically not allow you to establish a connection at 3pm (DynamIP would disconnect you automatically because 3pm is not bracketed by 2.15am and 2.25pm. If you check the box "Ignore DialTimerOFF if missed by more than 5 min", however, you would be able to establish a connection at 3pm without DynamIP interfering.
If this box is unchecked, DynamIP strictly enforces the settings of DialTimerON and DialTimerOFF.

Uploader

Active Check this box if you want to enable this particular connection.
Remote Host Name (or IP address) of your FTP server (e.g. ftp.alpha.edu). Do NOT put any paths or directory names into this field (the remote path must be specified together with the name of the remote file).

Tip:
If you enter the value <!--skip--> DynamIP will NOT upload the updated local file to your remote host. This is useful if you want to test whether your template gets updated properly.
Login Your login id (for the FTP server).
Password Your password (for the FTP server). Warning: although all passwords are encrypted before they get stored to the file DynamIP.INI you should be aware of the fact that the encryption algorithm is rather simple and won't hold up serious hackers for too long...
Template ONline Path and file name of the ONline template (the file containing place holders for IP address, Date and Time, etc. that will be uploaded to the server when you go ONline); this file is a read-only file and DynamIP will never change this file. The updated file will be stored as LocalFile. Make sure that the template file name is different from the local file name; DynamIP does NOT work properly if these two file names are identical!

Tip:
If you enter the value <!--skip--> DynamIP will upload the raw local file without changing it. This is useful if you want to upload WebCam pictures (see also "refresh every").
Template OFFline Usually the same as Template ONline. However, if you want to upload a different page when you go OFFline you can choose a different template here.

Tip:
If you enter the value <!--skip--> DynamIP will upload the raw local file without changing it. This is useful if you want to upload WebCam pictures (see also "refresh every").
Local File Path and file name of the updated file (local copy). Make sure that the template file names are different from this local file name; DynamIP does NOT work properly if these two file names are identical!
Remote File Path and file name of the remote file (the Local File will be uploaded to this location). If your HTML file goes into your root directory on the server then you don't need to specify the path (e.g. DynamIP.htm will work fine). However, you can specify the path if your HTML file must go into a particular directory (e.g. WWW/DynamIP.htm if the file goes into your directory WWW). Do NOT put the IP address or the host name into this field!

Tip for GeoCities users:
You should NOT enter any directory information as you are automatically loged into your home directory. Only the file name is needed, e.g. DynamIP.htm.
IP Place holder for your IP address; this can be any string you like (NOT.ON.LINE.NOW works just fine and is probably quite useful). This entry must obviously agree with the appropriate text string in your template.

Note:
The strings for IP, DateTime, WEBchat, HTTP Server, and FTP Server must be different if you don't want to end up with a total mess being posted…
DateTime Place holder for the current date/time; this can be any string you like ($DateTime works just fine). This entry must obviously agree with the appropriate text string in your template.
HTTP Server Place holder for your HTTP Server. This is NOT the IP address (or URL) of your HTTP server, but a placeholder which DynamIP will replace with a piece of HTML code that will become a link to the HTTP server at your current IP address. This entry must obviously agree with the appropriate text string in your template.
FTP Server Place holder for your FTP Server. This is NOT the IP address (or URL) of your FTP server, but a placeholder which DynamIP will replace with a piece of HTML code that will become a link to the FTP server at your current IP address. This entry must obviously agree with the appropriate text string in your template.
FTP UserID User ID that is inserted into the template if you check FTP Server. Default value is anonymous, but you can change this if you want your users to login with a particular ID (for example to find out from which particular web site they access your FTP server).
Immediate Retry on Failure If set to True DynamIP will immediately retry the failing operation. If set to False then DynamIP will wait for a while before retrying (this waiting period depends on the "idle-disconnect" period of your ISP).
#Retries Specifies the number of attemps DynamIP makes to upload the file if it doesn't work out the first time.
Delete Remote File before Put This switch indicates whether you want DynamIP to delete the remote file before it uploads the new file. If the box is not checked, DynamIP attempts to overwrite your existing file which should preserve the file permission settings. Note, however, that some FTP servers do not allow overwrites. If you get the impression that your uploaded file never changes then you must probably check this option so that DynamIP deletes the old remote file before uploading the new one.
Binary Transfer Leave this option unchecked to upload web pages (or any other text file). If this option is checked DynamIP will upload the file in binary mode (this is only useful for non-text files, e.g. WebCam pictures).

The following settings are common to all connections:

AutoONline If AutoONline is checked DynamIP automatically uploads the ONline templates of all active Uploader entries whenever the IP address changes (this includes the change from 127.0.0.1 [not connected] to something else [connected]).
AutoOFFline If AutoOFFline is checked DynamIP automatically uploads the OFFline templates of all active Uploader entries before disconnecting or shutting down. Note however, that this doesn't work if you lose your connection unexpectedly (e.g. if you ISP drops the connection).
refresh every If you are connected DynamIP automatically uploads the ONline templates of all active Uploader entries at user-defined intervals (this is quite handy, for example, if you want to update a WebCam picture once a minute or so).

Tip:
If you enter the value <!--skip--> into the field "Template ONline" DynamIP will upload the raw local file without changing it. This is useful if you want to upload WebCam pictures.
Timeout DynamIP aborts the going ONline/OFFline process if the operation is not completed within the user-defined interval. This setting should be left at 65 seconds until multi-threading works properly.
Async If this option is checked DynamIP uploads the file in asynchronous mode (that means DynamIP does not "lock up" until the file has finished uploading). Note, however, that the path and the file name get converted to all CAPs if you check this option (the problem is a bug-ridden VB5 FTP control!). If you uncheck this option DynamIP "locks up" until the file has finished uploading, but at least the file name does not get changed.

E-mail

Active Check this box if you want to enable this particular e-mail account.
POP Server Name (or IP address) of your POP server (note that an error message "bad IP?" usually indicates that you did not enter a valid POP server name.
Login Your login id (for the POP server).
Password Your password (for the POP server). Warning: although all passwords are encrypted before they get stored to DynamIP.INI you should be aware of the fact that the encryption algorithm is rather simple and won't hold up serious hackers for too long...
Notify Sound Check this box if you want DynamIP to play a sound file whenever you receive new mail. You can choose any WAV file you like. Clicking on the button "Notify Sound" will play the sound so that you can test your settings.
E-mail Client Check this box if you want DynamIP to automatically start your e-mail client whenever you receive new mail. Some clients (e.g. Eudora) can be launched by directly executing the EXE file, others must be launched via a shortcut. Generally speaking, the following two methods should work in most cases:
  1. point to an executable (EXE file)
    This method works fine with Eudora. For example, if the executable of your Eudora copy is in the directory C:\Eudora then you would enter the following text into the field E-mail Client: C:\Eudora\Eudora.exe (you can obviously also just use the file dialog box to select the appropriate file).
  2. point to a shortcut file (LNK file)
    This method works with MS Internet Mail, Netscape Mail, Pegasus, MS Exchange (and probably just about anything else out there). Simply point to the shortcut of your client, e.g. C:\Windows\Desktop\Microsoft Mail.lnk. (note that you can also point to a shortcut in your start menu, e.g. C:\Windows\Start Menu\Programs\...\*.lnk). If you need to submit command line switches then you put them best into your shortcut file. Basically you want to make sure that double-clicking the shortcut does exactly what you want your e-mail client to do. If you then execute the shortcut from DynamIP everything will work out just fine.

The following settings are common to all connections:

Check E-mail on Connect If this option is checked DynamIP automatically checks all active mail boxes whenever a Connect event occurs.
every ... min If you are connected DynamIP automatically checks all active mail boxes at user-defined intervals. Hint: you can also use this as a "Keep Alive" feature.
Timeout DynamIP aborts the mail checking process if the operation is not completed within the user-defined interval.

IPchat

Active Check this box if you want to enable IPchat.
Handle Enter your handle, nickname, pseudo, whatever.
Name Enter your name*.
Note that this information is also used in WEBchat.
e-mail Enter your e-mail address*.
Note that this information is also used in WEBchat.
Location Enter your location (e.g. city, country)*.
Comment Enter anything you like (e.g. your quote of the day).
Join Sound Check this box if you want DynamIP to play a sound file whenever a new participant joins IPchat. You can select any WAV file. Click on the button "Join Sound" to test your settings.
Hail Sound Check this box if you want DynamIP to play a sound file whenever another chat participant hails you. You can select any WAV file. Click on the button "Join Sound" to test your settings. Note that WEBchat uses the same WAV file to notify you of incoming WEBchat messages.
Chat Font You can select any font you like. The default font is MS Sans Serif.
Enable IPchat on Connect If this option is checked DynamIP automatically turns on IPchat whenever a connection is established.
Scan Interval DynamIP scans all IP addresses (as defined in IPDB.txt) at user-defined intervals.
Sleep at Startup If this option is checked DynamIP automatically turns on IPchat's "Sleep" mode whenever a connection is established.
Silent Chat participants are automatically removed from your chat list if their IPchat engine has kept silent for more than the specified number of minutes. This setting should be somewhat higher than your scanning interval, otherwise you loose participants. The Silent setting is used to clean out those chat participants who got disconnected on their side before their IP chat engine was able to sign off.
Short Chat Output Click this box if you don't need detailed information about the sender of each IPchat message (e.g. time the message was sent, IP address, etc.).
Auto Distribute Chatlist Check this box if you want DynamIP to pass on your complete chat list to all new participants as they join. This makes for somewhat more transparent communication (if you know what I mean...).
By Invitation Only If you don't want to be bothered by people who just happen to scan your IP range you can check this box. Only people with an IP address in your very own scanning range (as defined in IPDB.txt) are allowed to join your chat list.
Accept NetMeeting Requests Check this box if you don't mind other chat participants establishing a NetMeeting connection with you. Unchecking the box helps you keep away those lamers who don't get it if you tell them to stop bothering you (after all, it takes a couple of seconds to fire up NetMeeting even on a fast P200...).
IPDB file Enter the name of the file that contains the IP addresses you want DynamIP to scan. Clicking the button "Edit IPDB file" starts your text editor (the one that is associated with the file extension TXT, usually Notepad.exe). Clicking on the button "Add Chatlist to IPDB" adds all your current chat participants to your IPDB file.

You can specify IP address ranges to be scanned as follows: each IP address range must start on a new line, either with a "+" or a "-" (without the quotes). Here is how it works:

IPchat: You can include ranges or exclude individual IP addresses:

include: +a.b.c.from to (all IP addresses from a.b.c.from to a.b.c.to)
exclude: -a.b.c.d (excludes the IP address a.b.c.d)
HTTPscan: IP address ranges are specified the same way they are in IPchat. You can also specify a particular page to be the root page (in brackets [.]) and name HTTP servers (in parentheses (.)). For example, if you want to specify the DynamIP home page on my personal web server, assuming I'm somewhere in the range 36.173.0.0 .. 220, then you would add the following entry to the file IPDB.txt:
+36.173.0 220 <cmuServer> [DynamIP.htm]

* While I personally think that it is rude not to disclose your true identity I'm also aware of the fact that doing so might expose you to unwanted harrassment. Use your own judgement as to how much information you want to disclose and what data you want to keep private.

Note that the fields "Name" and "e-mail" are also used by WEBchat. Other WEBchat settings must be made in Setup|WEBchat.

WEBchat

Active Check this box if you want to enable WEBchat.
WEBchat Form Place holder for WEBchat form; this can be any string you like (the default value is <!--WEBchat-->). This entry must obviously agree with the appropriate text string in your template. You can also specify the number of rows and columns of the WEBchat form in the appropriate fields.

Note:
The strings for WEBchat Form, Name, e-mail, and Reply must be different if you don't want to end up with a total mess being posted…
Name Place holder for your name (WEBchat uses the same name entry as IPchat)*. The default value is <!--WEBchatName-->.

Note:
The strings for WEBchat Form, Name, e-mail, and Reply must be different if you don't want to end up with a total mess being posted…
e-mail Place holder for your e-mail address (WEBchat uses the same e-mail entry as IPchat)*. The default value is WEBchatMail.

Note:
The strings for WEBchat Form, Name, e-mail, and Reply must be different if you don't want to end up with a total mess being posted…
Reply Place holder for the reply box. The default value is <!--WEBchatReply-->.

Note:
The strings for WEBchat Form, Name, e-mail, and Reply must be different if you don't want to end up with a total mess being posted…Enter your location (e.g. city, country)*.
WEBchat Template You can optionally define a template that DynamIP will use as your WEBchat reply page (if you don't define a template DynamIP generates a simple standard reply page).

Important: Because the DynamIP WEBchat reply page is not served from the standard HTTP port (usually port 80) relative links on your page will not work properly. You must either define all links as absolute links (i.e. they must start with http:// ...) or not use any links at all. For the same reason you will also have to define all images, sounds, etc. with absolute references.
Submit Button Text DynamIP places this text to the right of the button "Submit" in the WEBchat form . The default value is

(or send e-mail to <a href="mailto:WEBchatMail"><b>WEBchatMail</b></a>),

but you just about anything goes. DynamIP will automatically replace the substring WEBchatMail with your e-mail address. As my e-mail address is "cmu@bigfoot.com" the text to the right of the submit button will look as follows:

(or send e-mail to cmu@bigfoot.com)

If you click on the button "Default Settings" DynamIP will reset all the entries to their default values which are guaranteed to work with the sample WEBchat template.

* While I personally think that it is rude not to disclose your true identity I'm also aware of the fact that doing so might expose you to unwanted harrassment. Use your own judgement as to how much information you want to disclose and what data you want to keep private.

HTTPscan

Active Check this box if you want to enable HTTPscan.
Template This is the file that is read after a successful HTTPscan, updated (only if it contains the string specified in ServerDummy) and then saved to LocalFile (only if the LocalFile box is checked).
Local File This is the file where the updated Server Template is written to after a successful HTTPscan (only if the LocalFile box is checked).
Server Dummy Specification of the string contained in ServerTemplate that is replaced with the list of HTTP servers found by HTTPscan. This is a place holder for the list of HTTP servers found by DynamIP. The default value is <!--ServerList-->.
Server Timeout Time in seconds DynamIP is waiting for a reply from an HTTP server when scanning a particular IP address. Bigger values slow down the search, but they increase the chances of finding HTTP servers (especially if they are slow). Values too small make it more difficult to find HTTP servers because they might not respond within the timeout period. A value of 5 should be ok for most practical purposes, but you might want to increase this if you have a slow link…
Load Local File in Browser Check this box if you want DynamIP to automatically load the updated web page into your favorite browser as soon as HTTPscan is finished.

Please refer to IPchat for information on how to define IP address ranges to be scanned.

DIPS

Please note the information provided below might be outdated. For the most recent DIPS setup information you should connect directly to the DIPS site at http://DIPS.home.ml.org/. Also, if you run into problems using DIPS please send e-mail directly to DIPS@bigfoot.com and not to me. Thanks!

Active Check this box if you want to enable DIPS.
DIPS Server The name of the DIPS server. At the time of writing this was postmodem.com, but make sure you check out the DIPS site at http://DIPS.home.ml.org/join.htm for the latest version of this entry.
URL Update Enter the URL of the update script. At the time of writing this the correct entry was /dips-admin/update.cgi?, but make sure you check out the DIPS site at http://DIPS.home.ml.org/join.htm for the latest version of this entry.
Topic Enter the name of the topic that you want your site to be listed under. The topic name should not contain any special characters (i.e. only "A".."Z", "a".."z", and "0".."9" are allowed).
Password Here you should enter the password that DIPS sent you with e-mail when you joined the service (you can join DIPS at http://DIPS.home.ml.org/join.htm).
Auto Update Check this box if you want DynamIP to automatically update DIPS information. For example, as soon as DynamIP detects your web server (HTTPD) it updates the information with the DIPS server.
Timeout Time in seconds DynamIP is waiting for a reply from the DIPS server. Bigger values increase the chances of successfully updating your DIPS info with the server. Values too small make it more difficult to properly connect and update the information. I recommend to keep this value at the maximum of 65.

Again, much more detailed information is available at http://DIPS.home.ml.org/.

Non-Standard Ports

Warning Changing ports is for advanced users only! If you don't know exactly what you're doing chances are you're in for some serious trouble down the road if you change them. Please do not play around with these settings, it's really only for experts!

DynamIP uses the following standard port settings:

FTP 21  
NTP 37  
HTTP 80  
DIPS HTTPD 80 This is the port of your local web server (HTTPD on your machine). DIPS verifies the existence of a web server before DIPS information is uploaded.
POP 110  
WEBchat 1498  
UDPchat 1499  

If you need to change any of the above ports you have to edit the file DynamIP.INI as follows (note that the standard ports are not written to the file, you only have entries for those ports that are non-standard):

To change this port Add the following line to DynamIP.INI Example with default values
FTP PortFTP=<PortNumber>; PortFTP=21;
NTP PortNTP=<PortNumber>; PortNTP=37;
HTTP PortHTTP=<PortNumber>; PortHTTP=80;
DIPS HTTPD PortDIPSHTTPD=<PortNumber>; PortDIPSHTTPD=80;
POP PortPOP=<PortNumber>; PortPOP=110;
WEBchat PortWEBchat=<PortNumber>; PortWEBchat=1498;
UDPchat PortUDPchat=<PortNumber>; PortUDPchat=1499;

If you change the UDPchat port, you will obviously not be able to chat with any other DynamIP user (unless she/he changed the port to the same number...).

If you want to revert to the standard ports you simply delete the non-standard entries from the file DynamIP.INI. (do this when DynamIP is not running!).

Please Note: I accepted a job with Credit Suisse Group (Group Risk Management) and will be moving back to Europe. Because of this relocation (first to Switzerland, then to the U.K.) I can only offer reduced support for DynamIP. Please try peer support in the DynamIP Discussion Group if you don't get a timely response to your e-mail inquiry.
