Tunneling Server Which Tunnel Incoming And Outgoing Connections And Make There Ping Appear To Be 0 In Server
Jul 25, 2010I have a server which has around 300+ users on it. Though the problem is that its coded in VB6, and if somebody has a bad ping, everybody has a bad ping. I need a tunneling server which will tunnel the incoming and outgoing connections and make there ping appear to be 0 in the server. Client to Server, Server to Client.

View 2 RepliesVS 2008 Server Program Can Receive SMTP Messages From Other SMTP Servers
Aug 14, 2009I'm using the TcpClient and TcpListener classes to read/write to the network when a request comes in on port 25. All I'm trying to do at the moment is make it so that my server program can receive SMTP messages from other SMTP servers. I've tested in Telnet - if I connect to my own IP on port 25 and type EHLO, MAIL FROM, RCPT TO, DATA etc then all works as it should and the details I entered are logged by the program (it doesnt do anything about delivering these details/email yet).all looks good... but then when I try and just send an email to my domain from my work account I can see that a connection is made to my program and the string "EHLO workdomain.com " is received by my program - my program responds to the remote SMTP server with "250-mydomain.com Hello" and then a CrLF and then "250-OK". After that point however, my app does not receive anything further at all from the server at work. I'm guessing I am doing something wrong with the data I'm returning when it sends EHLO but can anyone point me in the correct direction?
I was using telnet to test with, it seems that I have made it work only with telnet.In telnet each time I type a key the data is passed to the server, however with a real SMTP server it just sends each entire command in one go. So after altering my server a little I can now get it to respond with the 250-OK which I thought it already was doing.. but it still doesnt work. The remote server just sends EHLO and then thats it nothing more.Something interesting, at the moment I am ending all of my responses to the remote server with VbLf - if I change this to VbCrLf (which is what I believe it is meant to be according to the SMTP standard) then I get an infinite amount of empty strings sent to my program (or perhaps some other character that just shows as an empty string in intellisense when stepping through the code). Changing it back to just vbLf or ControlChars.Lf makes it go back to just sending EHLO and then nothing else..
VS 2008 - Send Email In Application Directly By The Smtp Server But The Server Doesn't Allow?
Aug 11, 2010i'm tying to send email in my application directly by the smtp server but the server doesn't allow me to do that.The application its used by everyone in the company, so i set the smtp client UseDefaultCredentials to True, but the server replies with this when i try to send an email:[code].....If i set the credentials by hand, the server sends the email. So my problem is how to make this work to everyone? I don't want to have one public/friend var all time in the application with the credentials of the current user?

VS 2008 : SMTP Server - Split The Sending And Receiving?
Oct 22, 2009 I'm trying to write my own SMTP server at the moment so that people can use it in their applications to send and receive emails.I am having a few problems at the moment with the TcpListener side of things though. Basically I do not want to start the TcpListener in the constructor of my class because people could be using this SMTP Server class just to send emails and might not care about receiving them. In fact the majority of people that use it will probably use it for that reason, to send and not to receive.
So I am now considering breaking this into 2 totally separate projects that have no dependencies on each other, but could easily be used in the same application if required. The reason I designed this with both 'features' in the same project in the first place was because that is how an SMTP server works - it can receive incoming SMTP requests and it can send SMTP server requests to other servers (and in some cases, receiving an SMTP request would cause it to send an SMTP command to another server)
Creating A SMTP Server That Has The Ability To Hide Ip Addresses In Email Headers?
Sep 5, 2009I have taken an interest in creating a SMTP server in vb.net that has the ability to hide ip addresses in email headers.I see that some people claim that it's possible around on the internet, but I haven't seen any direct source code to create an anonymous smtp server in visual basic 2008.Now I know that it's legal to send emails via a masked ip address and I believe that it's also fair since some people believe in anonymity, but I am in all means against spammers.

Jan 19, 2009It doesn't look like much is out there after searching but I was wondering if anyone has seen any vb.net projects to create a simple outgoing telephone dialer? Maybe something that can talk to a PC modem?
I'm not sure but was even wondering if this is something that can be done in a procedure? Doesn't look like there are any features that lend itself to it.
I thought also, I may do something with an RS232 stream and then use an external hardware dialer.....if I did that, I'm sure I could do the code in a Sub.
Get The Exact Call Duration Of Outgoing Calls From A PBX?
Feb 29, 2012Recently I've been into PBX call accounting programming on VB.Net 2010. My results are way too successful including friendly user-interface and connection datareceiving coding. Except for one. That is the call duration of calls, incoming and especially those outgoing. In my project I didn't use any API (like TAPI for PBXs) thus is there any option how to detect the state of the outgoing call, whether is still ringing, ended without answer or answer at some point of time...because in my project nevertheless what call state is being processed, I'm getting the total call duration from the moment that call was initiated to the moment is being finished or not-answered.
Here is a sample of my project where the DataReceived event is fired whenever there's something to parse from PBX to the PC.
Programming language : Visual Studio 2010 Ultimate - Visual Basic .Net
Database : Microsoft SQL Database
PBX Machine : Panasonic KX-TEM824
P.s. If you need to provide some code I'll post a sample of my project where the DataReceived Event is being handled.
