Configuration file

Gosna doesn't work if you don't setup config file for save the urls and file names and other config

There are three ways the Gosna tool take config file from them

1 - gosna_config env

2 - ~/.gosna_config.json

3 - -config option

The defualt config file will be

{
  "Config": {
    "Is_first": false,
    "Directory_work": "/home/user/work/",
    "Directory_result": "/home/user/result/",
    "Channel_use": "None",
    "Channel": {
      "Slack": null,
      "Mail": {
        "Tls": true,
        "From": null,
        "To": null,
        "Host": null,
        "Port": null,
        "Email": null,
        "Password": null
      }
    }
  },
  "Target": []
}

Usage: ./gosna [options]
   -run          Run type [add,check]
   -timeout      Requests timeout (default 5)
   -thread       Requests thread
   -header  -H   Requests header
   -repeat  -r   Repeat Check  [m,h,d]
   -dynamic      Check dynamic (default false)
   -config       Config file   (default ~/.gosna_config.json)
   -no-color     Disable color

Normal Usage

There are two run type

• add
• check

Add for add the url to check it later

cat url.txt | gosna -run add

Gosna will gets the url content then format it

Then save the content in directory work file

And add it to config file in Target json object

Chcek for check the url if there change

gosna -run check

Gosna will gets the urls from config file then get the new content And save it in the work directory then diff the new content with new content

Reapet check for diffrent time by flag -repeat or -r In this options you have 3 subs options [m,h,d] minute,hour,day You can use one of this options in flag -repeat or -r by

gosna -run check -repeat 1m

Dynamic Usage

Here simply how check dynamic works when add

1 - Send 5 request and save them responses in tmp directory

2 - Get the the dynamic lines from the responses in the tmp directory

3 - Save the bigest response length

4 - Remove the dynamic lines from the file saved

5 - Add true in object is Target[n].Status for knowing the tool it is dynamic url

Here simply how check dynamic works when Check

1 - Check the url is dynamic or not by Target[n].Status

2 - Send request and remove the dynamic lines then save it in the file in work directory

3 - Diff the old content with new contnet

cat urls.txt | gosna -run add -dynamic

Some time Dynamic option not working well

Let's imagen we need to monitor the https://www.youtube.com/

Because the it printing diffrent line number in each request

The tool will printed this url in each check
