Sometimes when you have to test connectivity a web service you can not always trust what he says your web browser (corporate proxy, firewall policies, etc. .)...
So to avoid the application layers, security, etc ... can access the desired Web server from the console of our team. What we found out with this?
- If we do not have a console connection, the problem is the connectivity (firewalls, routers, etc.)..
- If you access from your PC, but since the browser does not: the problem is in your browser settings, proxy policies, etc.
1. Type: telnet la_web_quequeremos_probar.com 80 (where 80 is the port hhtp, 443 if https want).
2. Once Connected to tell us ... means that we have connected and have connectivity.
3. If we see that there is no answer we can type: 3rd
GET / HTTP/1.1 . Intro 1 time
Pulsmoas 3.b host: loquequieras . Press 2 times intro
3.c We get a churro text your browser is what makes a website visible.
