firewall

My organisation produces a suite of Windows applications that make use of networking, and so when users run our software for the first time, the Windows Firewall (if it is running) brings up a pop-up, informing the user that our app(s) are trying to use the network, prompting the user to allow or deny access. This occurs with plenty of other apps (Spotify, to give one example), but ee'd like to prevent these popups from happening, as they can be a bit problematic for our users. Some Applications (MSN Messenger, GoogeTalk) operate without ever causing the Firewall to alert the user, and we'd

I have a Ubuntu linux system acting as a gateway system with two interfaces on it. One interface is for the local network and one interface is for the internet. I am able to route traffic through it with no problem at all. I use two iptables rules to forward outbound traffic from the internal interface: iptables --table nat --append POSTROUTING --out-interface eth0 -j MASQUERADE iptables --append FORWARD --in-interface

I'm extremely excited about html5's websockets spec but I have a concern. These days everyone is operating off of some network, with routers (wired/wireless) that have built in firewalls, windows has a built in firewall too. With that in mind when the server attempts to connect back to the browser that started the websocket handshake will it fail for the vast majority of users? (most people have no idea how to set up port forwarding on their routers) Or is my thinking incorrect and it will go through fine? Mark Renouf I'm not an expert (so please check to confirm) but I believe there will be

There is a cool utility out there called sshuttle . It has depended on ipfw to forward packets in the past. It appears that ipfw is mostly broken in Mavericks and the advice is to use PacketFilter for this now. I've spent most of the day looking at PacketFilter and it appears ipfw has a feature that PacketFilter does not support (hope I'm wrong about this). The following rule: ipfw -q add 12300 fwd 127.0.0.1,12300 tcp from any to any not ipttl 42 keep-state setup will forward all traffic to 127.0.0.1 (localhost) port 12300. It does not, however, change the destination IP or port in the TCP

We are developing a site that will require the usage of a captcha service. Has anyone successfully use Google Recaptcha for a website for users from Mainland China? Did you have major problems with load-time? Did you experience any reliability problems? Any problems with the great firewall of china? Any experience that you can share is appreciated. i can't even open the Recaptcha page you linked to without VPN. i've been in Beijing the last two years. assuming you're not here and/or don't know very much about the infrastructure situation in the PRC: i'm not aware of any service of Google's

I'm a little hesitant to post this, as I'm not completely sure what I'm doing. Any help would be wonderful. I'm on a computer with a firewall/filter on it. I can download files without any difficulty. When I try to clone files from Github, though, the computer just hangs. Nothing happens. It creates a git file in the folder, but the key files don't get loaded in. For context, I'm working on a Rails app, trying to load in Restful Authentication. Have any of you dealt with this? Any suggestions for getting the clone to work? Disabling the firewall might be an option, but if I can do something

I want to programme my own anti distraction tool. I can not / do not want to use hosts or third party apps. When using IPSEC or Windows firewall, it only accepts IP adresses. There is youtube.[264 TLD] www.youtube.[264 TLD] subdomains.youtube.[264 TLD] Appearantly there is no way anymore to get a complete list of youtube sub domains. Can someone think of a way to somehow obtain all youtube ip addresses and block them on ip level other than using brute force subdomain pinging? Shiplu Mokaddim If you have your own DNS server you can block domains from resolving. Here is a guide to block domains

i've got another question for you. I have Amazon EC2 instance with mondodb installed. It works great except one thing - i can't access (connect to) it from outside (my PC). I think the problem with Security Groups. It's some sort of default firewall. Does anyone know how to configure EC2 instance to have access to mongodb? Thanks in advance. You need to add a security group exception for the port 27017 if you are using default config for you to access it from outside. For security group configuration, please check the amazon EC2 documentation. And if you are using a different port on Mongo,

I would like to write a Personal Firewall on Java that can drop network packet. Is it possible? I want to capture a packet on jpcap, but how can i do drop packet? Is there a library in this event on java? And sorry for my bad English. I would like to write a Personal Firewall on Java that can drop network packet. Is it possible? No. I want to capture a packet on jpcap, but how can i do drop packet? You can't drop packets with either JPcap, in any of its at least 3 incarnations, or its native component libpcap/winpcap . Is there a library in this event on java? Not that I'm aware of, and I'm
