Re: [twsocket] TWSocket and SSL
Hello Daniel, I think you first need a little background knowledge about SSL and then you can apply it with ICS components. You should probably read the book (or at least parts of it): "Network security win OpenSSL" by John Viega, matt Messier & Pravir Chandra. O-Reilly. ISBN 0-596-00270-X. You can find it on Amazon and in any good book store. This book is very interesting for you because ICS-SSL is based on OpenSSL. ICS-SSL components hide the complexity of OpenSSL programming, nevertheless, the fundamental information is the same. Just skip any code section. -- francois.pie...@overbyte.be The author of the freeware multi-tier middleware MidWare The author of the freeware Internet Component Suite (ICS) http://www.overbyte.be - Original Message - From: "daniel cc" To: "ICS support mailing" Sent: Thursday, January 13, 2011 9:41 PM Subject: Re: [twsocket] TWSocket Yeah, Many thanks Arno :) Rebuilding did help.

Re: [twsocket] TWSocket and SSL
Hi Francois, Thanks for the response :) I don't have the book yet but I have already collected some info. Here are few unclear things, 1) Do I need to install the OpenSSL to the machine? 2) How do I use the batch file for making the keys, the batch file is made by you and it is founded in SSL directory of the component, this batch file looks real good but how it works? 3) How do I set the keys for each client and where do I keep the keys in the server? 4) How about the root certificate, where do I keep it, in my server directory? You see, I need to first understand the basic things about the component and will go for the secrets of SSL after that :) Thanks in advance With best regards -daniel -Original Message- From: Francois PIETTE Sent: Friday, January 14, 2011 11:12 AM To: ICS support mailing Subject: Re: [twsocket] TWSocket and SSL Hello Daniel, I think you first need a little background knowledge about SSL and then you can apply it with ICS components.

Re: [twsocket] TWSocket and SSL
I don't have the book yet but I have already collected some info. Here are few unclear things, 1) Do I need to install the OpenSSL to the machine? Yes, but this is simply copying the two OpenSSL DLL 2) How do I use the batch file for making the keys, the batch file is made by you and it is founded in SSL directory of the component, this batch file looks real good but how it works? You need the book to get the command line utility syntax. 3) How do I set the keys for each client and where do I keep the keys in the server? You don't need a key per client on the server. 4) How about the root certificate, where do I keep it, in my server directory? Open OverbyteIcsWSocket.pas and search for "Reference guide" in the comments. -- francois.pie...@overbyte.be The author of the freeware multi-tier middleware MidWare The author of the freeware Internet Component Suite (ICS) http://www.overbyte.be -- To unsubscribe or change your settings for TWSocket mailing list please goto http://lists.elists.org/cgi-bin/mailman/listinfo/twsocket Visit our website at http://www.overbyte.be
[twsocket] SslWSocketServer Send and receive
Hi guys, 1) I need to send from SslWSocketServer to SslWSocket, - Files (upload and download) - Commands. Commands are just text lines like: change IP Address, change display resolution, reboot the machine ETC. 2) I need to send from SslWSocket to SslWSocketServer, - Files (upload and download) - Commands. Commmands are just text lines like: CPU temp is: 60%, HDD space left: 10% ETC. Please notice!! I am not asking you to tell about how to change the ip address or how to get CPU temp. I just need to know about how to send the message and how to receive the message. How to upload the file and how to download the file. Thanks in advance Best regards -daniel -- To unsubscribe or change your settings for TWSocket mailing list please goto http://lists.elists.org/cgi-bin/mailman/listinfo/twsocket Visit our website at http://www.overbyte.be
Re: [twsocket] SslWSocketServer Send and receive
1) I need to send from SslWSocketServer to SslWSocket, A socket server cannot send any data to a client. The client has first to establish the communication with the server. At server side, a new socket is instanciated by SslWSocketServer to handle the communication with that client. Then once the connection is open, it is working in both directions. A server has to wait until the client connect. That's exactly what make a server a server: passively waiting for client connection. - Files (upload and download) - Commands. Commands are just text lines like: change IP Address, change display resolution, reboot the machine ETC. As far as the socket is concerned, files or commands is exactly the same thing. A socket with an established connection is a bidirectional transparent data stream. What you send at one end is received at the other end. To send a file, you read the file block by block and you send each block. You'd probably add some metadata in front of the file data so that the receiver know at least the file size and maybe filename, timestamp and so on. Basically that is what HTTP protocol is doing. You can reuse HTTP or design your own protocol. Commands being simple text lines, the socket has a line mode which will facilitate your programming. When line mode is active, the socket will assemble incomming data into lines and trigger OnDataAvailable for each complete line no matter how it is spread into packets of various sizes. 2) I need to send from SslWSocket to SslWSocketServer, - Files (upload and download) - Commands. Commmands are just text lines like: CPU temp is: 60%, HDD space left: 10% ETC. See above. -- francois.pie...@overbyte.be The author of the freeware multi-tier middleware MidWare The author of the freeware Internet Component Suite (ICS) http://www.overbyte.be -- To unsubscribe or change your settings for TWSocket mailing list please goto http://lists.elists.org/cgi-bin/mailman/listinfo/twsocket Visit our website at http://www.overbyte.be
Re: [twsocket] SslWSocketServer Send and receive
Thanks Francois, Sorry for not making myself clear :( I already know these. How do I send text comand from server to the client after it has established a connection to the server? how do I do the same thing from client to the server? for example: Server sends "Hello client" to the client and client answers "Hello server" to the server. a little example perhaps? And how do I do the same thing with the upload and download? like server sends some file/files to the client and client sends some file/files to the server. a little example?
