firewall

问题 I've heard that you can, during installation, add an exception for your app to give permission for it to access the internet through the firewall. Anyone know how to do this? 回答1: The alternative in many cases is to suggest that users disable the firewall entirely or ok the prompt Windows raises when your server ports begin to listen. Both of these are bad options: one risks leaving the machine open to anything and the other trains them to approve security prompts uncritically. You could

问题 When I listen on a port on localhost, Windows will popup a dialogue in which the user must add my program to the list of firewall exceptions. This is annoying, and requires administrator-rights, which the user may not have. Why does Windows do this for loopback connections (127.0.0.1) and is there some trick to prevent this? 回答1: The answer was to specify: IPEndPoint localEndPoint = new IPEndPoint(IPAddress.Loopback, Port); instead of IPEndPoint localEndPoint = new IPEndPoint(IPAddress.Any,

问题 When I run Get-NetFirewallProfile I see that the Domain profile Enabled is set to True. However, when I go to Control Panel > Windows Firewall the Domain profile is turned off by the GPO. Also, in Windows Firewall with Advanced Settings, the Firewall state is "Off". I'm not sure why the powershell output is different than the GUI. Please help!

问题 I need to delete some rules with same comment. For example I have rules with comment = "test it", so i can get list of them like this: sudo iptables -t nat -L | grep 'test it' But how can i delete all PREROUTING rules with comment 'test it'?

问题 I am new to TCP/IP and trying hard to learn basics. Well, I really wonder about inbound rules and outbound rules of Firewall and concept of source adress:port, destination adress:port. For example I am investigating port 80. I know that http uses port 80. But when I try to listen the traffic I see that my browser doesn't use 80. As you see from the image only destination port 80 is used and "destination" should be the server that hosts web pages not my computer. And also there is no used port

问题 We're using Capistrano to automate pushing new versions of a PHP application to a production server. The production server (we'll call it production) is public, while our repository server (we'll call it repo) sits behind our corporate firewall, along with our own machines. Capistrano, as configured by default, won't work, as production can't talk to repo. I was wondering if there was someway I could setup capistrano to SSH to repo first, then SSH to production opening a tunnel on a port that

问题 When I run a python application on Mac, it shows many dialogs about want "Python.app" to accept incoming network connections. Even I Allow it many times, it shows again and again. How to allow it one time and not show any more? Edit I found this question: Add Python to OS X Firewall Options? I followed the accepted answer to do but finally when I run codesign -s "My Signing Identity" -f $(which python) , it said: /usr/bin/python: replacing existing signature error: /Applications/Xcode.app

问题 I'm asking my network admin to open up ports on the firewall to allow remote debugging. It says in the documentation on MSDN that it needs UDP 135. However, the admin says that a number of non-standard 19xx ports are being used. Exactly what ports are required for remote debugging to work? 回答1: You need to open ports on both your computer and the remote computer. Primarily it's TCP 135 not UDP 135. All the ports and steps are listed here: http://msdn.microsoft.com/en-us/library/h0d7tte4(v=vs
