How To Ping Machine Given Hostname Or IP Address

Apr 11, 2005

I have a module that will ping a machine given a hostname or an ip address. Is there an eaiser way to ping a machine using vb .net? I know you can use wsh to open a shell and execute the ping command from a command prompt window then use the ReadAll to get the information ping sends back and from there you can determine if the ping was sucessful or not. How would I do this in VB .Net or is there a better way to ping machines in .net?

GridView - Check Each Row And Do Ping To IP Then Write Result

Jul 14, 2009

I have a gridview with two cells cell(0) is a IP-number and cell(1) is a resultTxt. I have X number of rows. I want a solution that check each row and do a ping to the ip and write result to result. I want to do the ping in a new thread and i want to be able to do more then one at the time. So I want a loop that keeps checking the ones that are not online until they goes online. It's the thread-part I have questions about, looping gridview and doing a ping I can manage, but it I don't do it in a thread the interface freezes.

I 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 ?

Get All Servers From AD And Ping Check?

Feb 1, 2012

A 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.

vb.net
Private Sub Button3_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button3.Click

Ping The First Record In Database?

Mar 14, 2009

I currently have the below code to ping the first record in my database.

I'd like to set it up so that if an IP in the Database pings, it moves on to the next record e.g NetMonListDataSet1.Addresses.Rows(2).Item(0).ToString. if it doesn't receive a response it "sendsmymail()".

I know i need a For Each loop somewhere maybe? But i can't seem to fit it in.

How To Ping Proxies ? Ie In IP:PORT Format

Dec 26, 2010

Well 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.

Ping.sendasync Memory Leak?

Jan 23, 2011

I'm having a strange issue with a memory leak associated with ping.sendasync. My program has a section in it that allows the user to specify X number of servers/computers to monitor.About every 30 seconds it will execute a routine that loops through the list and sends a ping asynchronously to each server/computer.If I keep an eye on the process memory usage in the task manager it will creep up about 1-1.5MB each time the routine is executed. Now, this program will be used and left running for hours and hours for each person, and over the course of the day the mem usage can creep up close to a gig...... (it happened the other day until I noticed it)

Server Indicators routine (starts the ping.sendasync):
Public Sub ServerIndicators()
ReloadingServers = True

VS 2008 - WinXP Ping Successful But Not Win7

Jan 19, 2012

I have a sub that I just discovered does not work for my windows 7 users but works fine for my windows XP users. This is basically a sub for a ping monitor to ping devices on a timer. What happens is that when the windows 7 user tries to ping, it always reports "down" on a windows 7 whether actually up or down. But, windows xp will report correctly with "up". 3 different windows 7 boxes, users say it worked before. Can't quite debug correctly as i'm on xp myself and it works just fine. Also, I haven't changed anything in the code in quite awhile and this is a recent bug that just started.

Private Sub Timer1_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer1.Tick
Dim itm As Object
Sec = Sec - 1

VS 2008 ASYNC Ping - Writing To TextFile?

Dec 6, 2009

I was trying to edit to get the reults output to a text file. I needed to do this for a few hundred IP addresses, and found kleinma's code. It works great as is, but since the number of IP addresses to ping is so large, I lose some of the info from the console session. I tried to make changes to write the information into a text file, but it doesn't output the results. I am relatively new to VB.NET, so I was wondering if you could please point out the flaw(s) in the edited code. I was trying to use the My.Computer.FileSystem.WriteAllText(File, lineContent, True) method to do this. This does export the IP address list just fine, but the results of the async ping to not get output.
