Hi Again Steve,

This is resolved now. It appears that I was not doing the initiation and authentication with the proper number of linefeeds and with the proper sequence of writes AND reads. For those interested, here is a working function written in vb.net to do the communications on the localhost machine. The assumption is made that the password has been changed from ClueCon to myPassword in modules.config.xml and that mod_event_socket is loaded in modules.conf.xml using the entry: <load module="mod_event_socket"/>.

Thanks to all for the help.

Bert

Function SendCommands_socket(ByVal id, ByVal Cmnd)

'Funciton to initiate conneciton with FreeSWITCH event_socket via a tcpsocket, authenticate and send a command.

'Note that the writes AND reads are all mandatory, as are the double linefeeds.

'Dims

Dim returndata As String = "" 'Holds return data

Dim sendBytes As [Byte]() ' byte array used to hold outbound data after conversion from ascii to byte array

Dim tcpClient As New System.Net.Sockets.TcpClient() ' the tcp socket client used to communicate with the host

Dim rcvBytes(tcpClient.ReceiveBufferSize) As Byte 'byte array used to receive bytes returned from host

Try

'Initiate conneciton with event_socket via the socket--------------------

tcpClient.Connect("localhost", 8021)

Dim stream As NetworkStream = tcpClient.GetStream() 'open the socket

returndata = Encoding.ASCII.GetString(rcvBytes)

MsgBox(returndata) 'should say "Content-Type: auth/request"

Thanks for the clarification. I too suspect something in my communications. Just wanted to make sure I was not missing something. Will move my communication app to a separate machine from the FS server and run Wireshark. Thanks for recommendation.

Without the use of the ESL *protocol* - no. Without the use of the supplied ESL *libraries* - correct.

You're along the right lines on implementing your own protocol. If you can connect and authenticate via telnet from the same computer you're trying your app from then there should be no problem with FS.

The fact you say it takes 10s for FS to respond indicates you're not sending the auth line. You should get either a success or failure message straight away in reply to that. So it sounds like the auth isn't getting sent at all.

Try using Wireshark to view what's going over the network to check it's what you expect.

Hello,

Am I correct in assuming that an app can talk directly to FS using event_socket without the use of the ESL? I am attempting to do this, but having trouble authenticating. I wanted to make sure I was not overlooking something basis in my approach.

I have successfully loaded FS on a windows XP server and can register phones and make calls. Further I can talk to the server, authenticate and make calls using telnet, but when attempting to do the same via an app written in .net and using a socket, I am unable to authenticate.

Running my app using a tcpSocket, I receive the "Content-Type: auth/request" upon connection of the socket, but when sending “auth password\n\n” it appears that the connection times out after about 10 seconds and I receive: “Content-Type: text/disconnect-notice" & vbLf & "Content-Length: 67". mod_event_socket is enabled in modules.conf.xml .

Is there something obvious that I am missing conceptually, or should this work?

Thanks!
