I have a web side hosted on IIS, windows 8 os. I can access from my browser to this page via these urls:
localhost/mysamplesite
192.168.21.10/mysamplesite
I can ping my ip address like this: ping 192.168.21.10
But I can not ping to 192.168.21.10/mysamplesite this command gives error: ping request could not find host 192.168.21.10/mysamplesite
Actually have another machine (192.168.21.45) that installed apache banchmark on. I want to test request from apache banchmark to my site. So I can not send request.
ab -n 1 -c -1 192.168.21.10/mysamplesite
This does not work.
As arco444 mentioned, you can't ping a website, just a computer itself.
ping is the first thing to try when troubleshooting network connectivity problems
ping 192.168.21.10
from the remove machine.
You can also try PsPing to test for connectivity to a certain port:
psping 192.168.21.10:80
however you can not use this to check for a particular resource on your web site.
Instead you have to use a tool to test for http traffic, Apache Benchmark is one of them, depending on the OS on the remote machine, there are many other tools.
If ping works, check the firewall settings on your Windows 8 machine.

I'm having a hard time viewing Wildfly welcome page on port 8080 + tried apache on port 80 too, and they timeout. I can ssh to the server and using (curl localhost:8080) and (curl localhost:80) show Wildfly and apache welcome pages respectively. I have checked the Security List and Security groups and even opened ALL traffic just to see if they are causing this problem, but unfortunately the problem still there.
I'm using ubuntu 20.04 image and the UFW (firewall) is inactive so the problem isn't from there.
By default every oracle instances come with 2 firewall.
Hardware Firewall (Known as VCN)
Software Firewall (They use a very hard iptables rules and regular ufw doesn't work with that.)
The 2nd option is very annoying and also took me about 3 days to solve my problem. You can follow my following instructions and hopefully it will also fix your problem.
1st you have to open the port on the Hardware Firewall (VCN) and when you believe you have opened the port then by login to the server using ssh use this command to clear the default oracle iptables rule.
sudo iptables -F
But remember whenever you will reboot the server you will need to again run the flash command. So if you don't want to run this command every time after server reboot. Then after running the flash command run this command to save your flashed iptables rules.
sudo netfilter-persistent save
So, you will not need to run the iptables falsh command every time on the startup of the server.

I have a SOCKS proxy forwarding port 9999 on my local machine to a remote development server. I use that proxy connection with Firefox so that I can access the dev server's network, but I also want to be able to forward localhost connections in Firefox to the remote server's localhost to connect to various services running there. I have removed localhost and 127.0.0.1 from the "No proxy for" setting and it still doesn't work. How do I make it work?
You have to change another setting, in addition to removing localhost and 127.0.0.1 from the "No proxy for" box: set network.proxy.allow_hijacking_localhost to true in about:config.
This was changed recently. Source: https://bugzilla.mozilla.org/show_bug.cgi?id=1535581

I'm sitting behind a proxy server, which gives me a configuration and routing rules via a .pac file (configured in the global internet settings in windows).
There are some URLs that should not be routed to the proxy server, as they are local addresses in our company. There is also a rule to not route localhost. For development purposes, I have given my machine an alias hostname: 127.0.0.1 dev.company.com
Accessing the URL dev.company.com:8080/index.html with Internet Explorer or Firefox gives me the expected result, however, the same URL in Chrome gets routed to the proxy server, which (of course) is unable to find it.
You could run: chrome://net-internals/proxyservice.init_log#proxy in your chrome browser and re-apply your settings.

I have a Windows VM on Azure and I don't understand why my ping times out.
I found a probable reason: on Azure portal I see public IP "40.127.163.20", but inside VM when I do ipconfig I see different IP that is strange.
Do you have any ideas?
ICMP protocol is not permitted through the Azure load balancer (inbound or outbound) which means that you can't do a simple ping to your VM. There is a : user voice request for this to be enabled here.
This blog here describes how you can use a port ping as an alternative.
There is some documentation on how to set up an Instance Level IP, which would circumnavigate the load balancer and give direct communication to the Virtual Machine, but I haven't tried this approach (I'm giving it a go right now, will report back)

Im trying to use a proxy with firefox, but the issue is that some sites are getting my real ip.
-If I enter to http://www.showmemyip.com it shows me the proxy ip.
-If I enter to http://www.whatismyip.com it shows me the proxy ip + "No proxy detected"
-If I enter to http://whatismyipaddress.com/proxy-check it shows me the proxy ip + "Proxy server not detected." + everything on false (green)
How can it be possible that they are detecting my ip? I saw that flash doesnt use the proxy configured on firefox... but the pages that Im trying to access dont have any flash script.
Is there any way of being 100% that they would only see the proxy ip and not mine?
Thanks!
That because the proxy pass your ip to server in http header(detail), you should setup the proxy to anonymously.
There are some Java and Flash hacks to find out the visitor's real IP even behind a proxy server. As for Java you can turn it off forever. For Flash install some browser extension to be able to block it when you need. Use this site for tests: http://mylocation.org
