How To Ping Proxies ? Ie In IP:PORT Format
Dec 26, 2010Well I decided to try make a proxy checker, like Charion or Elite proxy checker. These programs accept large lists of proxies in the IP:PORT format, ping them tell you the response time see the screenshot of Elite Proxy Checker, im trying to make a simplified version of this program. [URL]I investigated and made my checker using Ping.SendAsync(ip, timeout, ip) method. It was only afterwards that I discovered that you can only Ping IP's using this method, not the ports as well. Ive spent a few hours trying to find the correct class/methods in order to be able to ping ports, reading different forum posts from experts they say its impossible to ping ports only IPS, can only use sockets to try open a connection with the port.

Oct 20, 2011I am trying to get my 4 port USB relay board to work in VB.net using the COM PORT. I found some code from a poster who has the 16 port USB relay version. When trying his code i can only get it to turn on relays 1-3 all at the same time. The product can be found here: USB 4 port relay

Ping Using VB - Performance ?
Jul 20, 2009I have this code to ping a list of over 400 switches , the program works fine but for some reason the first time i ping all the switches alot of the attempts time-out(even tho they shouldnt) which makes the program alot slower , if i click ping again less of the attempts time-out(and as a result the program runs faster) and if i click it a third time i usually get a completely accurate result with all the switches pinging back "success" (except for a few which i know for a fact are down anyway) any ideas why this is ?

View 1 RepliesGet All Servers From AD And Ping Check?
Feb 1, 2012A little background, the client that I am working with has an enterprise AD that is a mess. They have no containers for servers or any organization what-so-ever. They also shutdown servers and did not remove them properly from AD. So I needed to come up with a program that would find all the windows server, identify them by OS, and then check to see if they would actually respond to a ping. (I am aware that this is not a perfect method if they are refusing ICMP's but its good enough for my purposes). The completion of the program will display all the information and then allow the user to save the excel workbook in a location that they choose.
