asked on
ports of my website
how do i know the ports of my website (website hosting servers ?
thanks
thanks
A website by itself only uses port 80 for a regular connection or port 443 for a secure connection. There are a lot of other ports used in the operation of a server but that's all for just the web site.

well the thing is i am having problem in accessing my website from my LAN and it apparently seems Firewall problem . I am using juniper SSG20 and i know the standard ports are 80 and 443
thanks
thanks
You could use a portscanner to see what ports are open http://www.radmin.com/products/previousversions/portscanner.php
Can you access any website at all? Is your website on your LAN? If it is public, can you give us the address so we can check it?

MY website is hosted in US , what makes me think the issue is related to Firewall is because i can access the link outside of my company's premises . I have a strong feeling that the issues lies on my juniper firewall or else on my ISP Proxy servers . I know how to access the interface of my firewall all i am asking now is how to open a specific port in my jubiper firewall which i have already checked using port scanner ( 0-65535 port is closed ) i need to open this port 8080 lies in this range
thanks
thanks

If the website is hosted in the US, which I presume is an outside on the Internet from your firewall's prespective. Why would you want to open port 8080 on your firewall? Does an application or feature on your LAN or Firewall require you to open that port to access this site?
With the description given so far, I also don't think it is your firewall. Try these steps to see if you can get closer to resolving your problem.
1. If this is possible try resolving against different DNS servers than your ISP ones. Like Google name-servers or OpenDNS name-servers.
2. When you are in command-prompt. What do you get when you type "telnet [your website] 80", then type "GET" then hit Return. if you see the HTTP header with some 400 or 500 returned status code it means the website is listening to port 80.
3. These hyperlinks that you cannot access within your website when you are within your LAN. Are they linking to files or documents elsewhere and is the URL change at all to HTTPS or does it stay the same?
4. On command-line prompt again, can you try pinging the links that seem to not load and see if they resolve at all?

Please tell us the nature of the problematic link. What kind of data does it link to? Where is the data stored? Same site as the webpage or is it a link off site? What is the nature of the error? When you click on the link does nothing at all happen or do you get an error message or garbled data? If the latter, what does the error say? If you are still convinced that it is your firewall, that link i posted shows you how to open ports to specific protocols without opening security holes.
