Automatic Router Scripting Engine

aka. A.R.S.E.

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 (ARSE.ini) preferences.
Coloured entries cannot be set from the GUI, so if you want to alter those, hack your ini file..

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**)
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)

** 0 = no logging, 1 = log authentication/login only, 2 = log all responses (the default).

Inside the 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..

C:\Users\<YOUR-USER-NAME>\AppData\Roaming\corz\ARSE\DD-WRT v24\
C:\Users\<YOUR-USER-NAME>\AppData\Roaming\corz\ARSE\Voyager 205\

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. A.R.S.E. Main GUI showing available 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.

Inside 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 D-Link DSL-2680:


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)



Automatic Tasks..

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.

Command-line mode..

A.R.S.E. Document Icon arrow icon, pointing right A.R.S.E. Application Icon arrow icon, pointing right Router Icon

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..

ARSE main window+context menu 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.

ARSE Preferences Pane - telnet login, etc.. 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.

For scripters..

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.

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 reboot (or 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.

Exit codes..

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.

i love this program but i can't seem to get a script working for Call of Duty - Modern Warfare 2 has any one made a script they might want to share?

If anyone has scripts, mail them to me! I'll put them up here. ;o) Cor

Hello everybody

Is there some way how to detect that script in command-line does its job, or not? Some %ERRORLEVEL% mechanism used for command-line?
Yes, i know, that there is no way how to parse output from telnet. I need only information about succesfully connecting and ending telnet session...



Not currently, which is an omission. It's on my 2do list. ;o) Cor

[edit]Note: v2 now has this, and a lot more[/edit]

Thanks for the great software;

BUT WHERE IS THE DOWNLOAD LINK, I have tried for over two days looking for the,

No download link at the very top as well.

Thanks in advance.

Heh, yeah, it was temporarily removed while I worked out a few kinks. Sorree!
It's back now!

Do you plan on making a version that utilizes SSH instead of Telnet?


No, not currently. Security isn't usually a major concern on the single hop between folk and their routers. If enough people ask, or better yet, someone donates and asks, I would certainly look into it. ;o) Cor

First, confirm that you are human by entering the code you see..

(if you find the code difficult to decipher, click it for a new one!)

Enter the 5-digit code this text sounds like :

lower-case oh, Upper-Case Vee, too!, lower-case why, Upper-Case Queue


Welcome to!

I'm always messing around with the back-end.. See a bug? Wait a minute and try again. Still see a bug? Mail Me!
