firewall

问题 I want to use WCF to enable two way communication without opening a port on the client. I'm developing something like a P2P application (similar to teamviewer/logmein) where you don't need to open ports to communicate. How do I accomplish two way communication through HTTP/HTTPS without the need to open a port in the client? Note : Port 80 can be opened in the server...no issues on that. Thanks 回答1: Well those systems you mention work as follows. They first try to make client A and client B

问题 I have the keyword "cum" which our firewall uses to block adult sites, problem is this works a little too well because this also blocks any URL with the word "document" The firewall will take regex strings, and I tried this: ^.*(?!document)cum.*$ Vut it still matches "document". I have a feeling I should be using a pipe | but I don't get it. What I want is to match anywhere *cum* is found in the URL (or domain-name), but NOT if the word is document or documents . Possible? As I understand it,

问题 I am trying to solve the below issue, I have a iptables rule in my output chain which says that if the packet matches certain criteria, then queue it and send it to userspace using NFQUEUE The userspace program receives it,and once it recieves it, it checks if the packet is a tcp packet and if yes, it modifies the content of the packet After Modifying it, it sends out and I am able to see that till now it works properly, I was able to re-calculate the checksum and verify it and update the

问题 I need to open specific port for my application. I have tried using INetFwAuthorizedApplication rule per application for all ports. fwMgr.LocalPolicy.CurrentProfile.AuthorizedApplications.Add(app) Alternatively open one port for all appllications using INetFwOpenPort . firewallManager.LocalPolicy.CurrentProfile.GloballyOpenPorts.Add(port) Is there any way to programmatically open only single port per application programmatically? I can do it manually through firewall settings. 回答1: There's a

问题 I am trying to write automation to a little project that I'm doing in work. In the proccess I need to disable Windows Firewall (for every Windows version) using python (I prefer activepython because it already installed). I looked for many answers but I didn't found any answer that suits my needs. I found this site: https://mail.python.org/pipermail/python-win32/2012-July/012434.html But the problem is that when I check from the control panel the actual disabling of Firewall is not happening.

问题 I am working on a firewall project. So far I succeed to block packets by ip basis which is I done by windows filtering platform. But my customer does not want to block the whole ip. He wants to block specific url. So now I need to capture each packet and read it. So far I can do that by C# raw socket. But I dont know how to drop that specific packet. Please help me out on that. 回答1: Does this help you? http://www.osix.net/modules/article/?id=824 In this article the author reads packets in raw

问题 I can access sites when using browser, but when inside a Mac application I always get "Operation Timed Out" over VPN . Is this a companies firewall issue or my local DNS settings issue? I have been going back and forth with our IT admin team on this. With the same firewall roles Windows users are able to run things smoothly. Few Examples.. Mac Terminal himalay$ git clone https://github.com/spring-guides/gs-consuming-rest.git Cloning into 'gs-consuming-rest'... fatal: unable to access 'https:/

问题 I am charged with determining what would be involved with creating our own firewall. Something that can intercept each and every connection, and decide whether to permit it based on which exe is initiating the connection. We would either block or hang the connection until the user said to permit or deny. I am interested in XP, Vista, Win7. I know how to program in Java, Perl and JavaScript. I am assuming that I am going to need to get Java to interface with some C or C# executable in order to

问题 I have a wpf app that needs to communicate(exchange data) with a custom designed device (we can modify the code for the device). Do I have any options to connect to the device if it is behind a firewall via http? I was hoping there would be a method where the admin would not have to forward any specific ports or do anything on his end. I assume the issue is how would I address the device from my app. I know SOAP over SMTP is one option. Is another option where the device could chatter out to

问题 Consider the following scenario: Jenkins running with a master on machine A and a slave on machine B. Rather than the master's XML config referring to a hard coded Java path it was changed to reference 'java', in the environment PATH variable. This works fine for the master running on machine A, however the slave on machine B is no longer able to connect to the master host PC. The (Windows) firewall rules for inbound traffic on machine A allow inbound communication on any protocol and port
