Thanks mayamatakeshi. I added flushes after each send, but still not working. Setting up packet capture now.

The ESL is a plain text protocol. You can connect to the ESL port via telnet and type in the ESL protocol commands manually and it'll connect fine. -Steve On 13 February 2011 12:16, mazilo <Nabble@slickdeals.endjunk.com> wrote:

Sure, here is what worked for me using Putty First: enable mod_event_socket module in modules.conf.xml (It is enabled by default ) <load module="mod_event_socket"/> Next: configure in autoload_configs/event_socket.conf.xml as follows: <settings> <param name="nat-map" value="false"/> <param name="listen-ip" value="192.168.0.15"/> <param name="listen-port" value="8021"/> <param name="password" value="myPassword"/> <param name="apply-inbound-acl" value="lan"/> </settings> Then: configure Putty client as follows Set Putty to talk to server running FS over port 8021 using telnet protocol, open session, Finally: Open a telnet session and: Send blank line, Send "auth yourPassword", Send blank line. Receive "Ok" Bert -----Original Message----- From: freeswitch-users-bounces@lists.freeswitch.org [mailto:freeswitch-users-bounces@lists.freeswitch.org] On Behalf Of mazilo Sent: Sunday, February 13, 2011 7:16 AM To: freeswitch-users@lists.freeswitch.org Subject: Re: [Freeswitch-users] Possible to communicate with FS using event_socket without ESL?

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. -Steve On 13 February 2011 03:27, Bert Jones <rmbertjones@comcast.net> wrote: Hello, Am I correct in assuming that an app can talk directly to FS using event_socket without the use of the ESL?

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.
