Hey somebody please answer my noob question

>stop being a paranoid faggot
I literally can't. It's my nature. How can I check the html and the js files to see whether I contacted their server? Like I said in the above post - their server address needs to be identified somewhere, for that to happen right? Where would it be?? I've literally never coded in my life, I don't know any of this shit

you could also pull your Ethernet cable, but it won't contact any server my guy.

Please, just help me

I have the html and js files saved on my computer. Please tell me - where should I look in these files, to find out if my computer could have made contact with the server? Where would the server IP address/domain name/ identifying information be stored? What should I search for???

I don't know what the hell I'm doing, please help me

What drugs are you on right now?

Wireshark it.

Thanks user!!
I'm installing it right now. Would you mind please giving a quick noob tutorial on how to use it to get the information that I need? It would be much appreciated

Endogenous paranoia

user you are talking with seems dumb. Js in html page to connect to a server is very unlikely. Mostly impossible. Your saved page will not connect to a server. Unless you downloaded all js files together with it.

I dunno lol. I only know how to select an adapter to reduce a number of packets and then search on the web how to filter outgoing requests to 80/443 port.

Unless you downloaded all js files together with it.
That's exactly what I did, man...

Okay, what js files do you have? Which files are requested in that .htm page? It is possible that the js files are not placed in a location where the .htm file could find them. So like on the server they are in root/js, but in your case you'd have them in the same folder.

thats a comfy image

The saved html file may have other elements which is loaded from Internet, like images, css stylesheets, js scripts and possibly some other stuff. If you open your file locally the browser will access those and theoretically this is the way for the owners of the website to know you've opened the page. To check for this you should open the file in an editor and search for references to the original site.

check for anything in a script tag. If the deisgners weren't retarded the js will be in a different file ( ) however, which you've not downloaded. Also look for and the like.

The files included are: html, jQuery, modernizr, tinymce. All of them are requested in the html file.

My problem us, I have no idea how to analyse these files to see if they include a function that would contact the original server. I don't know what to search for - there is no mention of any do ain names (.com, etc) in any of the files. But would it use a domain name, or an IP address??

i use this since it redoes all the links to locally downloaded files and makes it fully offline.

jQuery is probably ajaxing some server. What kind of page are we talking about here and why do you care?

Many thanks for the reply user. I have actually downloaded all of the related files, including js files, along with the html. I used Firefox 'save complete webpage'. Therefore, all of the files were svaed locally. My worry is that one of the js scripts may have caused my computer to contact their server, after I opened the html file while connected to the internet. My question is - how do I check the js scripts to see if that could have been possible? There are no domain names mentioned anywhere in js files - but, being a pleb, I have no idea whether that even means anything.

user earlier mentioned Wireshark - any ideas how I could use that, to get the answer to my question?

>jQuery is probably ajaxing some server.
How do I check to see whether that is in fact the case?

>What kind of page are we talking about here and why do you care?
If I find the answer to my question, and I can be satisfied that my computer did not contact any server when I opened that file, I will explain everything. I just need to know what the fuck to do to find out.

>How do I check to see whether that is in fact the case?
well if you've downloaded everything locally, it probably isn't anymore.

hes on that pack

Well, if there is no urls or domains in downloaded files, then you're probably safe. BTW, you can tell the browser to work offline and it won't connect to the Internet at all. Firefox can do this, opera can do this, and I think IE too. Wireshark on the other hand can show you where your computer tries to connect and which data it sends and receives. I didn't actually use it, so can't tell more.

try the network tab on the firefox developer console.
i don't think you can use this feature retroactively, so you'll have to reload the page to find out. Won't do any harm, since if you reload the page and don't connect to a server, who cares, and if you do, then you already did.

My worry is that one of the js scripts that ran when I opened the html file would have caused me to contact their server. I need to know, for definite, whether this was the case.
There are no URLs or domain names in the html or is files - but what if the server is named by some other way, like IP address? Is that possible? How can I search a js file for an IP address?

Thanks user. I think this is the best suggestion in the thread so far
I'm not going to risk doing it again though. Can I make it work without having an internet connection up? And use it to see if a connection is attempted, or something?

Yes, you can make it work, I think Firefox even highlights the requests that are made but fail. No harm in trying anything if you've disabled your internet

yeah you could do that.

or if you want to do something stupid like search for IP addresses, use a regex "/\d{3}\.\d{3}\.\d{3}\.\d{3}/g" on an editor with a search capability that can use regexes. Can use vim even "/\d{3}\.\d{3}\.\d{3}\.\d{3}"—then press 'n' to go to next occurrence.

So I just tried this:
And the network tab shows nothing. Do I have to try it with an internet connection to be sure? Or can I take it to mean that the html file/ js scripts are not attempting to make any contact to any server?

no, I just checked to see if it works on a locally saved file that makes an external connection with my wifi off and the console on, and it shows the attempt.

Now dish why I've been humoring you for 20 minutes

the best way to achieve this is to install wireshark
set wireshark to start listening to your ethernet port and wifi port
stop all open browsers, stop all email and anything else that connects to the web
let the traffic go quiet then open the page locally.
if wireshark starts writing entries see if any of the connections are to the site
another way to stop the page connecting is simply to disable ethernet and wifi then open the page

>open linux terminal
>wget -rk myfurrypornwebsite.jp
>profit

I'm a man of my word
I will tell, I promise
I'm just trying to test it myself to be sure

OP you should honestly just provide a description of what you're trying to do. without that there really is no answer to this question. even if there is code that makes an attempt to access some resource on the internet, without having some knowledge of the code, or being able to look at whatever scripting language MIGHT be serving up whatever it might be serving, there really is no saying. if you provide some details as to what you're looking for, you might be able to get some better insights. this is a really shitty thread and you should feel bad about your post

I don't want to risk connecting to it again, if it does turn out to be the case
Would Wireshark pick up any attempted/failed connections?

it's not going to pick up anything the network console didnt in your case.
If you want to try it offline though, the software would be pretty shitty if it didn't record attempts made.

You lied to me man.

nope. what are you seeing?

yes

When I open a locally saved webpage, with an internet connection, the network monitor shows it making connections to the website. Even though I'm opening it locally

1. Turn off internet
2. Open your htm file with firefox
3. Open the console, then click the "network" tab
4. Press F5 to reload the page
5. See if there are any requests

How does this not work for you?

write entries in your hosts file
like this
0.0.0.0 the-bad-website.com

You misunderstood
I opened the htm earlier with an active internet connection.
When you do that, there are requests made to the server.
I just tried it now.

If you did and are still seeing requests *to a non-local URL*, then it's a good thing your internet is disabled because the htm file is trying to get stuff from external sites. If your internet is actually disabled, these requests should be failing and you have nothing to worry about.

of course. I never said otherwise. If you're offline it will attempt those same connections but show them failed is all I said.

can you give us some information goddamn
