Automatic Router Scripting Engine
This is A.R.S.E., the 'Automatic Router Scripting Engine'.
A.R.S.E. is a program which automatically sends command scripts (rules) to your router (or NAS, Managed Switch, IP Camera, Access Point, or whatever). Essentially, it does automated, scriptable telnet. You can setup or tweak your device with a click! Although originally designed to configure Voyager and compatible routers, A.R.S.E. now works with ALL devices that support telnet.
I have found the Automatic Router Scripting Engine invaluable when tweaking my broadband router for maximum download speeds. Doubling your DSL Line Rate is possible (my operator expects me to get no more than 4000 kbps, right now we're sitting happily at 9826 kbps!), but not without a lot of trial-and-error!
Wouldn't it be great to be able to quickly try out new configurations, and crucially, switch back to the old setup when our tests fail? Enter A.R.S.E., which makes tinkering simple and quick.
When you first launch A.R.S.E. it creates a folder in your user data folder, and creates another folder inside that for a
default device (as well as its default ini file with global settings)..
Here are the currently available (
Coloured entries cannot be set from the GUI, so if you want to alter those, hack your ini file..
[ARSE] current_device=DSL-2680 autosave_prefs=true autoupdate_list=true update_frequency=5 permanent_delete=false sleep_time=300 (time to wait between sending commands to device, in milliseconds default = 300) log_level=2 (if you want to see output (next pref), leave this set to 2 - the default**) show_output=true confirm_drop=true (confirmation of drag-and-drops scripts) do_debug=false (set to true to have a debug file left in the working dir) log_file= (this is best left blank - logs will be created in <data folder>\<device>\logs) editor=notepad.exe (enter the path to your own favourite text editor - for logs and ini files) associate_files=true
** 0 = no logging, 1 = log authentication/login only, 2 = log all responses (the default).
default device folder, is a
device.ini file, with settings and presets for that specific device. You can rename "
default" to whatever you like, and create other folders next to it, for other devices, e.g..
These devices are then available from a drop-down menu.
You can switch devices from the drop-down menu, and ARSE will re-launch itself with the new device's scripts.
ARSE remembers window settings for each individual device (including the progress dialog and log output window). You can run multiple copies, each set just-so, remembering their own window sizes and positions.
device.ini (the device settings) you can have four sections. A main
[ARSE] section where you can override certain global prefs (those which make sense to be device-specific - changing these in the GUI will set these for the device), as well as three other sections.
Easier to give you an example - this is for a
[ARSE] log_level=2 show_output=true sleep_time=400 log_file= autosave_prefs=true [device] ip=modem user= password=MyPa55word reboot_string="" (optional: enter whatever command reboots the device - for scripts that require reboot) auth_checkstring="Password:" (optional - ARSE will look for this before sending the password) login_chunks=2 (default is 8 - which is the number of 1KiB blocks to retrieve for login responses) max_response=300 (maximum amount of data blocks to retrieve in a single response, in KiB. Default is 300 - plenty!) line_feed=LF (what type of Line Breaks to use, default is CRLF. You can also use LF or CR) [view] width=375 height=247 x=1242 y=197 prog_x=518 prog_y=8 show_log_x=1258 show_log_y=45 show_log_w=664 show_log_h=999 [selected] DIAGNOSTICS=True
As well as its simple graphic interface, A.R.S.E. can operate command-line mode, so you can click a script anywhere and have it sent directly to the router. You can also drag-and-drop scripts directly onto A.R.S.E. - or a shortcut to it - and they will be sent immediately to the router via background telnet.
You can open your scripts folder from the A.R.S.E. scripts context menu (right-click any script in the list), though as you can add and delete scripts from right from within A.R.S.E., there shouldn't be much need to interact with the folder manually.
A.R.S.E. accepts script on the command line, which means you can drag-and-drop scripts onto the A.R.S.E. icon and A.R.S.E. will telnet them immediately to your router (and then exit). Or you can simply click a script anywhere in Windows Explorer and it will be sent to your router (so long as you have
.arse files associated with A.R.S.E - you can do that from the A.R.S.E. system tray menu).
In a similar way, you can schedule script to be run at any time with, perhaps the Windows® built-in "Scheduled Tasks", or some other scheduling/macro software. There's no need to leave A.R.S.E. running, but if you do, it uses very little resources, and can be toggled by its tray icon (left-click).
The currently available scripts are also available for running from A.R.S.E's system tray menu.
Note: in command-line mode, you will not be asked for any login preferences - unless the
device.ini file is missing, i.e.. the first time you run A.R.S.E..
or GUI..If A.R.S.E. is launched without any scripts (i.e.. you click the application, or a shortcut on your desktop, Start Menu item, etc.),
it will present you with its simple graphic user interface and your current script collection. I put more controls into this as I go along, so check back often for the latest version.
In GUI mode, you can drag and drop scripts into the list, to add them to your collection (one at a time), and also delete scripts from your collection, as well as do a few more things; right-click the list.
It's okay to run scripts from the command-line or schedule while the A.R.S.E. GUI is running, they won't interfere with each other.
Scripts are available for all sorts of things, mainly port-forwarding rules for p2p applications, ftp servers and the like, though technically, any valid telnet command can be placed in an A.R.S.E. script. Feel free to mail me your own pet scripts, and I'll chuck them here for all to use.
As mentioned, A.R.S.E. scripts are simply lists of valid telnet commands, the exact same commands one would enter in a telnet session with your device. A.R.S.E. scripts can also contain comments. Any line beginning with semicolon ";" or hash "#" is considered a comment.
The line format can be PC (CRLF - "\r\n") or UNIX (LF - "\n") line breaks, but NOT Mac (CR - "\r") sorree! - if your script jumps immediately to 100% progress, check your line-breaks.
Get More Scripts Here!
You can also embed "progress directives" in your scripts, like this..
[I am a progress directive]
which will be used as the text under the progress bar while the script runs. So, if you have a big script, you can keep users informed about what section is currently being processed. Peek inside "Basic-Voyager-205-setup.arse" with any decent text editor for example usage.
Note: If your script requires that the router do a reboot at the end of you script, add
reboot at the end of your script (after
commit, for Voyager routers). Don't worry about multiple scripts sending multiple
commit) commands (and the long wait that entails); A.R.S.E. stores these commands and performs them only once, right at the end. If a reboot is required, A.R.S.E. will warn you first, and give you the option to defer that, if needed.
If you are running scripts via Explorer, the command-line, a scheduled task or similar mechanism, you can grab A.R.S.E's exit code, so you know exactly what happened.
There are only a few of these, for now. As follows..
0 = Normal Exit. OK. -2 = Ini file not found. -3 = Device not defined inside ini (prefs) file. -15 = Login details incorrect. -16 = Login aborted.

Automatic Router Scripting Engine
Automated, scriptable telnet for your network devices..
itstory.. aka 'version history'.. aka 'changes'..
[known bugs at the bottom]
+ New stuff
++ Requested New stuff
Added ability to alter font and font size for log output. It now
defaults to a monospaced font, which improves readablility.
* Fixed a couple of prefs which were being read/written in the wrong scope
and/or section, namely; autosave_prefs and line_feed which will now work
+ Automatic ini updating. In case I add any new features to the ini
(prefs), this ensures you have the latest version. As usual (for my
apps), your current preferences will remain intact.
+ New icons all round, namely application icon, document icon and
alternative document icon (if you like to hack such things, you can get
a blue document icon by using 5 instead of 4 for the icon index. If you
don't know what that means, forget about it!)
+ Added portable operation. As usual with my apps, if there is an ini file
next to the program, it switches automatically to portable mode. Done.
+ Improved automation of initial and subsequent device creation. You can
create new devices by simply creating a folder in the ARSE data
directory (as ever) or setting current_device=whatever-you-like in your
ini file OR by simply right-clicking the device's drop-down menu and
selecting the "Create New Device" option - by far the easiest method.
+ Added option to delete a device from the devices drop-down context menu.
~ The current_router preference and [router] preference section have been
renamed to current_device and [device], respectively. Your old prefs
will be updated automatically (at least for the next few versions). This
is just FYI.
~ Lots of GUI/input/text tweaks for clarity and aesthetics.
~ The A.R.S.E. web page is now up-to-date with no trace of v1 information!
+ Added tray menu options for editing preferences (ini file) and also for
editing the log file.
+ A.R.S.E will now automatically check its file associations and repair
+ You can now easily associate and disassociate .arse files from A.R.S.E's
system tray menu. As well as the usual "Run this script" entry (which
does exactly that), an edit entry is also created, using whatever editor
you have set for your A.R.S.E ini/log editor (editor=something.exe).
* Fixed the sleep_time preference so it now overrides correctly on a per-
++ A.R.S.E Now works with ALL devices that support telnet, which is most
routers, IP Cameras, managed switches, etc., etc. Enjoy!
Too many changes to list.
See main page for updated documentation.
NOTE: There is now no installer. A.R.S.E. can setup its own associations
*** End of the line for A.R.S.E v1. v2 will bring ALL device capability! ***
fixed the major bug with new installs. if you were upgrading, everything was
fine. if it was your first install, sorree!
fixed the minor bug where the resolved IP address label slightly overlapped
the Ping indicator, making it tricky to click (you can click the icon to
retry the ping, you know).
added a preference for 'permanent delete'. check this and when you delete
scripts from your collection, they will be permanently deleted from your
scripts folder, as opposed to sent to the recycle bin (the default). If you
had manually set this to true (as per earlier tip), either change it to "1"
(no quotes) in your ini, or check the preference in the prefs tab (a better
ARSE now sports a new tabbed interface. the second tab is for preferences,
I have more tabs in mind, if time permits.
When hidden (left-click on tray icon) ARSE no longer pops up a "Success!!!"
dialog for you to click at the end of a script run, but instead puts
"success!!!" in the progress bar for a moment, and then promptly disappears.
(the dialog times out after a few seconds, but still, a background task should
This also applies to scripts run from the command-line.
I've begun adding tool tips to the controls, I finally found the function!
GUICtrlSetTip() <- whoever named this function needs a kicking!
In the address preference, if you enter a "name", it will be automatically
resolved to its IP address, which will be displayed on the right hand side
of the input (as soon as you leave that input). it is still saved as a name,
this is simply for your information. While ARSE is running, you could use
this facility to get the IP address of any internet name (enter the name,
then click on the octet readout, it will update and ping the host for you -
if you use autosave, remember to put back your router's address afterwards!)
Added a cute "tick" or "cross" icon for the DNS check. This was more trouble
than it was worth! Looks neat, though. (while it's checking a "?" is displayed)
All these icons are stored inside arse.dll, ensure you either run the installer
(do a reinstall with your new download) or else copy over the new arse.dll if
you are doing things manually.
you can click on the centre of the icon to ping the host again
you can right-click on the resolved IP address for an option to copy it to
If your login fails, ARSE will pop up the login details dialog boxes for you
to correct it. If you are running a script from the command-line, ARSE will
also try a second time to send your commands.
Fixed the bug where the icon refresher icon in the Start Menu wasn't being
fixed the bug where the address (stored internally as an octet) would be
displayed as an octet in the login preferences, even when you had previously
saved it as a "name". (mine is "router", which resolves to my router's IP)
Added tray menu items for "Run Selected Scripts" and "Run ALL Scripts"
so you can do these things when the main window is hidden (left-click on tray)
Added a tray menu of ALL the scripts in your collection, you can run
any script while ARSE is hidden by simply selecting it in the tray menu. This
list changes dynamically as you add and delete in the main gui.
Changes to the position of the progress dialog are now remembered
Thereafter, this position will also be used for the brief "login" window.
I removed that rogue "esc" key capture thing.
fixed the bug where as soon as one reboot is required, arse will keep bugging
you to reboot every time you send a script, until you quit. Now arse will only
bug you until you do the reboot, then it will stop, until another is required.
ARSE now looks at the *last* parameter on the command line for the path to the
script. this won't affect anyone becasue we haven't started adding switches yet,
but if you plan to create some custom actions, keep this in mind.
Your *current* selection is now saved and restored when you drag in a new
script, though, as ever, on exit, it's the last *successfully sent*
configuration that is saved (or, if that was unsuccessful, the last one you
*attempted* to send) in other words, just messing around with the selection
won't affect your "last known good" selection, and dragging *new* scripts into
ARSE will affect *neither*!
Added a concept menu to the list. From there you can (so far, and working fine):
* Resfresh the scripts list.
If you add a pile of scripts to your script folder manually, you can do
this to have them show up in your collection.
* Open the scripts folder.
In Explorer, for if you ever need to interact manually with your
scripts. Or else a handy way to get to the ini file (open, then hit
backspace "<-" which surely is programmed into your middle mouse button!
* Delete selected scripts (from your scripts folder)
Note, ARSE needs at least one script to be more than just a pretty GUI,
so if you delete *all* your scripts, ARSE will re-create the default
stealth script "for you".
Note, by default, scripts are deleted to your recycle bin. You can
change that by hacking the ini file, in the [ARSE] section (if that
doesn't exist, create it)..
I might do a prefs page yet, and a switch for this.
You can now drag and drop scripts onto ARSE and they will be added to your
sripts folder (and the list).
Switched mode of operation to "Mode 1", event mode, mainly to get above working.
This is probably a better way of working, regardless.
cleaned up some of the legacy code structures lying around (some!)
added a (right-click) tray menu with an "about" item, I forgot about an about
box! regular left-clicking on the tray icon toggles the main window.
Your last used selection is now remembered in the ini file, for next time.
note: by "used", I mean the last set you actually sent to the router.
Between the saving and the "toggle" function, it's possible to run a nice big
on/off switch, with the regular and "remove" versions of your scripts.
I moved ARSE's application data folder into the "corz" folder, best for
everyone. If possible ARSE will move your old folder to its new location
automatically, though it will err on the side of caution, and you may have to
move your scripts over by hand.
ARSE now only performs only one commit per operation, so if a dozen scripts all
needa "commit" command, ARSE performs it only once, at the end. saves 1.8
seconds per script.
Incorporated some stuff I learned making the installer.
Added a list menu of available scripts. Now you can select any number of scripts
to run. There's also an "all" button, which unsurprisingly, runs all available
Added "clear" and "toggle" controls, for rapid scripts selection.
Changed the ini file name from "router.ini" to "arse.ini", as it now holds
non-router prefs. old ini files will be renamed automatically, at least for the
next few versions, they will.
Window size and position is now saved (in arse.ini) and restored on launch.
ARSE won't ask for login details if an ini file exists, you did that already.
Added an "edit login details" button, should you wish to change the details
When multiple scripts are being processed, a reboot command is stored and sent
only at the end of the sequence, rather than "when it comes", which caused
multiple selections to only get partly sent. This would be a bug-fix if I hadn't
fixed it before I even encountered it.
Fixed a few minor bugs.
minor tweaks and adjustments, compiler directives, etc.
Added a HotKey (Esc) that you can use to exit Arse at any time.
Improved name resolution handling.
ARSE will now resolve host "names", so if you have a local host name for your
router (mine is called "router") you can use that in the address field.
ARSE will now recognize a "reboot" command in a script, and warn the user of the
impending reboot, as well as giving them the chance to cancel it, if they really
must (important transfer in progress, perhaps).
Removed the old one-time reboot warning (no need now).
Some GUI and progress bar improvements.
You can now enable "progress directives" inside your scripts. These look exactly
like ini section header..
[I am a progress directive]
Simply, when Arse finds one of these, it will use the text within for the
current progress message, so if you have a long script with many sections, you
can keep the user informed about which section of the script is currently being
Here's an example..
; disable nasty UPnP..
modify upnp cfg nbstatus disable
Don't overdo these because a) if there are too many, they will flash before the
users' eyes too quickly to read, and b) they are classed as *real* lines when
calculating the progress bar, so it would become (albeit only slightly)
See inside "Basic-Voyager-205-setup.arse" for more examples.
note: Arse no longer performs "commit" at the end of the run. If you want your
rules to be permanent, add "commit" to the end of your script.
Arse now accepts scripts on the command line. In other words..
a) you can drag-and-drop script files onto rah.exe (or a shortcut
to it), and they will be sent directly to the router, and..
b) you can script your ARSE!
When using the command-line or drag-and-drop, arse doesn't arse about
asking for your router login details (unless its ini is missing), just
sends the commands immediately. You still get a nice progress bar, though.
First there was a shell script for Linux called "RAD". It removed those
nasty rules the Voyager 205 inserts at bootup. (or rather, BT inserted!)
It's still around, works great, if you have a Linux box handy.
Then there was a Windows batch file, because, well, most folk still use
windows. It worked, but it had problems. The main one being that it spawned
a telnet window and "sent" key commands to it. If the user were to shift
focus to a different window, bad things happened, like launching infinite
copies of the same batch file. It came with a big warning..
STAND BACK FROM THE COMPUTER!!! TOUCH NOTHING!!
But folk still did, and bad things happened.
RichE did a nice GUI version of this, which was cooler than the batch file
but still suffered the same problems, sending keys to windows. But through
this I was introduced to AutoIt proper. Thanks RichE!
First it was a GUI version of RAD, then also a "RAH" "H" for "hacking"
because it could send commands other than the original "Router Automatic
Deletions", and could be packaged as a "one-shot" app that could setup
an application for someone. this lasted about two days.
RichE and I grappled with the code and ideas for a few days, until I
wrestled it off him for my first AutoIt project..
ARSE 1.0 combined the functions of both applications and a whole lot more!
Before you ask a question..
PLEASE remember, this page is about ARSE, which is FREE!
If you want to ask questions about routers, go here.
I haven't worked on ARSE since I first made it, and probably never will again, not using a voyager router myself any more, you see. Some of the code if probably fairly inept - I think it was my first AutoIt app - but it works great, so I don't feel the need to replace any of it with better techniques I've learned since, I'm happy to leave my "AutoIt progression" out there!
Arse stores the ini in the user's folder, doesn't it? So encryption isn't really necessary. (there's an excellent debate or two about this logic on the FileZilla forum)
As for the registry, I am NOT a fan of storing anything there unless I really have to. I get religious about this elsewhere on-site, I'm sure. ini files are real and tangible. A user can open them, edit them, move them, and importantly, back them up. Even with sophisticated backup and recovery scripts (which I have), the registry is a pain in the arse (the other arse!).
Every application I now make uses plain text ini files. In fact, I've done quite a bit of AutoIt coding since last we spoke (I today noticed that ffe has been listed on the ffmpeg project page, w00t!), including a cool desktop clock, color picker, and more. Hit the newish Windows button in the top toolbar for more details. Most things are still getting updated when I come up with new features and such. Not ARSE, though.
But Hey! The source is freely available, so feel free to do whatever you like with it. If you fully document all your changes, thoroughly test it, and provide the source, I'll even put up a download here, with credits and all that.
One thing I would like to add to ARSE, is the ability to set the login search strings. Currently it looks for something that the Viking router says during the conversation (particular Viking responses), but it would be nice to be able to set that, so that ARSE would work with any router. I wasn't thinking big enough when I built it.
I've had reports of ARSE working well on pretty much all the Viking I based routers, which is good, but working on all routers, period, would be better.
Anyways, back to my prose..
Thank you very much!
Your work and your application is great!
Greatings from Argentina!!!
The router-reboot script works with my UTStarcom WA3002G4 adsl router as well! This is awesome!
But only in the GUI mode !
I try and run it from the command prompt .. it does not work.
Even when I try and run if from the system tray .. run script .. it does not work.
Only when the GUI is running and I select from scripts.. and click run selected it works.
Hence I am unable to schedule it to run at odd times :o(
Any idea on how to make it work ?
Another one for the list! I must get that list up here sometime.
Only in GUI mode? How strange! I can't remember there being any difference between running scripts from the different controls; they all go through the TelnetRouter() function (or whatever it's called).
Feel free to poke around in the source code and solve this mystery!
Hi, COR. Great job!!
Do you know a command for drop the PPPoE session and then restart another one without reboot? I'd like to renew the Public IP address given at starting PPPoE session.
Thank you very much.
Not off-hand, but I'm fairly certain there's one in the Viking manual (pppup/pppdown, or somesuch). If you don't have the CLI Manual, you can download that from the main Voyager 205 page.
I was looking at the CLI Manual before posting but the "modify" word confused me.
Rechecked it, I found the command I was searching for is
Nice site useful
