0 down vote favorite I have created a network scanner, that looks for a specific port on a range of IP's. I would like to thread the application but I am getting and error message ERROR: for worker in range(network.hosts): TypeError: 'method' object cannot be interpreted as an integer Now I understand why the error is there it is because the IP Address is not an INT. However, what I would prefer to do is split the subnet into equal parts and run X number of IP's on a per thread bases. Example Thread 1 192.168.1 - 30 Thread 2 …

Hi All, I am looking for a design approach to implement TCP socket server which is going to serve requests based on multiple ports. (1) port1 : dedicated for video streaming (2) port 2: dedicated for audio streaming (3) port 3: dedicated for data streaming. In above scenario do i need to create single server to take care with multiple port request or diff-2 server needs to be created for diff-2 request based on port configuration. Is there any design strategy where connection pool of sockets can be created to serve above mentioned port based requests? i appreciate if any …

Issue: I need example.no-ip.org to point to example.no-ip.org:20202 I have read that this is not possible with just DNS. However no-ip.org lets me set up DNS SRV (records?). Ive have followed this guide to set it up, but it does not redirect to IP : PORT [url]http://www.no-ip.com/support/guides/other/configuring_srv_records_with_no-ip.html#1[/url] Still cant get it to work. example.no-ip.org only points to the IP, no port. Q: Is it possible to do what i describe? Q2: How? Is it just my SRV setup that is messed up? Here is a screenshot after creating the records(?): [URL="http://i43.tinypic.com/219b6om.jpg"]http://i43.tinypic.com/219b6om.jpg[/URL] (five was the default level of priority) Thanks to …

Hello, I really need help getting my ZyXEL router to forward the ports I need. I have tried going to Network > NAT > Port Forwarding and setting up the correct information, doesn't work. I've tried disabling the firewall on Security > Firewall > Active Firewall (unchecked), doesn't work. WAN to LAN and LAN to WAN connections are all permitted, I've tried disabling my PC's firewall and it still doesn't work. Portchecktool.com (given from no-ip.org which is what I'm trying to use) says that all my ports are blocked except the ones in use by the other services (80, 8080, …

Hello, I have installed apache 2.2 but when I try to make it listen to 80, I can browse the target page and access denied error is displayed. But when I change the listening port to say 8080, I could browse using this port. I have already tried to check if the port 80 is used by some other service or not using netstat -an But only port 80 is listening to only local address, and process id corresponds to httpd.exe as well. That really surprises, if http.exe starts on port 80 but in the browser access denied error is …

Hi, I have a device connected to the USB port of the laptop. This device pumps data to the port which is read by the python script. As per the baudrate of the board I use folowing configuration to open the port. Serial(options.port,921600,timeout=0.2,xonxoff=0,rtscts=1) But when I analyse the collected LOG file I see lot of data miss in between. Looks like buffer is over written.

I have an interesting challenge and was hoping one of the gurus can assist. I have a program running on a client machine that I need to "trigger". The program is written in VB.NET. What is the easiest way I can generate a "trigger" to that client machine? Couple of things I already considered: a) check for a presence of some file (too cumbersome) b) implement sockets and listen on some port for a trigger (too complex, error prone) c) check some website for a presense of something and use that as trigger (too much work, must setup site, read …

I've recently installed a new CPU (Core2Quad Intel) and my computer no longer stays on for more than a minute. All bios are updated and the computer runs fine on my old CPU (pentium d duo). The new CPU is cool to the touch after a shutdown, so heat is most likely not an issue. However, research suggests that a shutdown so quickly and abrubtly is heat releated, so is it possible that the new CPU somehow is 'tricking' the computer into thinking it's overheated? Heat sinks function fine, given the tempurature of the new CPU and the flawless performance …

Hello, I trying to create a **messenger**(just for practice, so nothing fancy!). I created the server and client programs. Suppose a client(user A) initiated a connection with the server, so it's online. Now, another user(user B) wants to chat with that user(A). How do I give User B the IP address of User A. I have tried this one, `String ipAddress = connectSocket.getInetAddress().getHostAddress();` this returns me the IP address. But dont User B needs the port number of User A also to connect with that user(A)? If yes, *then how do i do it*? Any advice will help. thanks.

Hello everybody, I have decided to start working on an application for my customers which will allow me to maintain their computers remotely using VNC. I currently have a very basic VNC system which I plan to customize for my own use (All in C#). The problem I now face is that for my customer, having to set up port forwarding on their router is not desirable and in most cases very impractical as the very nature of my customer base is to not have a very good working knowledge of anything computer related beyond basic usage.

I'm using the Virgin Mobile Overdrive Hotspot as a temporary setup for now until I get service out here. Anyway, I'm using the port forwarding settings on the device. ![mobile](/attachments/large/3/mobile.JPG "mobile") I am saving it each time, restarted the computer and the mobile hotspot device. I checked if the ports are open and they are not. Just to see if it were the ports, I enabled port 80. Still not open. ![Capture111](/attachments/small/3/Capture111.JPG "") ![Capture211](/attachments/small/3/Capture211.JPG "") I have the same setup before I moved with a router and cable modem and it worked, but not this hotspot.
