Remote control of clumsy

[jvanegmond]

In order for clumsy to be deployed in automated test runs, it is necessary to be able to control clumsy from other applications.

Ideally clumsy would:

• Expose a RESTful service or a TCP service with a simple protocol allowing:
  • Start and stop an get current state
  • Get and set filter
  • Set and get options for different functions
  • Enable or disable the different functions
• Automatically ignore the control connection when modifying the packets (maybe simply by adding a part to the filter automatically).

I'm thinking of implementing a command line version and you can specify the parameters on start up. Would this meet your requirements?

[jvanegmond]

Yes, I think that would satisfy the requirements. We can always add network control later as a wrapper around the command line version.

[jagt]

Cool! I'll try to get this done.

@jvanegmond I've uploaded a new release accepting command line options. There's no doc yet, but it's pretty easy to figure out the arguments in the commit 046572c .

An example:

clumsy.exe --filter outbound --drop on --drop-chance 50

tks @jagt , your commit fix our big problem.

Hello, I was wondering if there was a way to have clumsy start when it opens, as I am opening from the command line, but having to interface with the GUI and press the start button removes my ability to automate its use, thanks!

[rafarojas]

I would like to send the delay value of 70ms, I tried with:
.\clumsy --lag on --lag-delay 70

But it doesn't work. What should be the parameters?

[Ehntae]

Change --lag-delay to --lag-time!

[rafarojas]

Awesome, thanks ;)

[rafarojas]

BTW, do you know where I can find documentation for those commands?
@aeomi on my tests I don't have to click on "Start" if I send at least one of the parameters, like drop, or the lag-time. But if I don't send any parameter it doesn't start right away and I will need to click on Start manually

[Ehntae]

I see, that isn't what happens with me, I've had to use AHK to controlclick the start button when the application starts. I would still really like a command line based version of clumsy, it would definitely make the task of automation far easier. Also, as far as I know there is no documentation for it, however, you can view the source code and figure out most of the parameters from there is what I think the dev said.

I would like to start clumsy from command line with these parameters :

Filters:
inbound and (ip.SrcAddr = 10.40.2.181 or ip.SrcAddr = 10.40.2.134 or ip.SrcAddr = 10.40.2.157 or ip.SrcAddr = 10.40.2.113 )

Functions:
Drop Inbound Outbound chance 10%

What are the clumsy commandline parameters?

thank you

[inequity]

@fabry00 Add those settings to clumsy's config.txt as a new filter, then specify --filter filter_name to use it.

[rogierschouten]

any chance of documentation?

[nddipiazza]

https://github.com/jagt/clumsy/wiki/Command-Line-Arguments @rogierschouten there you go

[rogierschouten]

Thx!

Hi, it would be possible to lag udp packets targeted to a outbound multicast ip?
If yes, which would be the correct configuration?.

Thank you in advance

[moerwald]

Found this sample in config.txt. May help:

udp ipv4 against port: udp and (udp.DstPort == 12354 or udp.SrcPort == 12354)

So your filter could be:

udp and ip.DstAddr == 224.x.x.x
