Here's the situation...
I've got a working program that sends commands to various computers using
the RemoteExec service. There's one pc that doesn't seem to reply. It
accepts the connection but never replies. So my program just sits there in
a "not responding" state waiting for the reply and I have to "end-task" it.
Here's the code where it locks up. Look for the 3rd "debug.writeline" in
the code...that's where it locks up. Is there a way to have this timeout?
Or otherwise abort the function and allow the program to continue on with
the next pc in the list?
Thanks.
'Create a socket connection with the specified server & port (512 is the
remote execute port)
Dim s As Socket = connectSocket(txtRemotePC.Text, 512)
If s Is Nothing Then
MsgBox("Unable to connect to Remote PC", MsgBoxStyle.Critical)
Exit Sub
End If
'Send message to the repeater
Try
s.Send(ByteGet, ByteGet.Length, SocketFlags.None)
Catch ex As SocketException
Debug.WriteLine("s.Send: " & ex.Message)
Catch ex As Exception
Debug.WriteLine("s.Send: " & ex.Message)
End Try
'Recieve the response from the repeater
Try
Debug.WriteLine("s.Receive") <-- locks up after writing this to
the debug window.
bytes = s.Receive(RecvBytes, RecvBytes.Length, SocketFlags.None)
Debug.WriteLine("s.Receive complete") <--never gets here, never
throws an exception
Catch ex As SocketException
Debug.WriteLine("s.Receive: " & ex.message)
Catch ex As Exception
Debug.WriteLine("s.Receive: " & ex.Message)
End Try 2 1327

You can set a Receive timeout value...
' all receives will timeout after 5 seconds of waiting for data...
s.SetSocketOption (SocketOptionLevel.Socket,
SocketOptionName.ReceiveTimeOut, 5000)

Thanks! That worked like a charm. I set the timeout to 15 minutes
tho...sometimes it takes that long for a response. This thread has been closed and replies have been disabled. Please start a new discussion. Similar topics |
