I'm using the Cloudtrax HTTP Authentication API to create a custom logic for router authentication that has a captive portal.
When the router asks for a status request, the server responds the following:
"CODE" "ACCEPT"
"RA" "1c65684265a2bb1a7c87e4d9565c2b18"
"SECONDS" "3600"
"DOWNLOAD" "2000"
"UPLOAD" "800"
Which should be de correct format of an answer to login the user. The problem is that the captive portal is still present.
I don't know what could be the problem and I can't find a log on the router or cloudtrax to see what could be wrong.
Edit:
I am processing the RA string on django (python):
import hashlib
def calculate_ra(request, response):
    code = response.get('CODE')
    if not code:
        return ''
    previus_ra = request.GET.get('ra')
    if not previus_ra:
        return ''
    if len(previus_ra) != 32:
        return ''
    previus_ra = previus_ra.decode('hex')
    m = hashlib.md5()
    m.update('{}{}{}'.format(code, previus_ra, SECRET))
    response['RA'] = m.hexdigest()
 
                        
Use SSH to log into the router and enable debug mode by sending these commands:
Then use
logread -fto view logs in realtime.Don't forget to disable the debug mode when you're done:
