How do I send a file .txt or .evt between two computers using TCP/IP

I need send files but just found how tranfer cha.

Answer 1

[Walter Roberson]

file_as_char = fileread('YourFile.evt');

Now file_as_char is char that can be sent.

I'd say "by email". More seriously, if you need to build a client-server system, look at the following:

http://www.mathworks.com/help/instrument/using-tcpip-server-sockets.html

The example is easy to run on two distinct machines, and you can send a file content this way.

        %cliente
        t = tcpip('192.168.7.195', 50000, 'NetworkRole', 'client');
        fopen(t)
        pause(2);
        fprintf(t, 'Hola sub 2');

        %servidor
        t = tcpip('0.0.0.0', 50000, 'NetworkRole', 'server');
        fopen(t);
        data=fscanf(t);

I managed to pass a message ' hello world ' from a PC to another, but I want to do is send an .evt file I have on my PC to another PC . could you help me to send and receive the file ?

[Walter Roberson]

t = tcpip('192.168.7.195', 50000, 'NetworkRole', 'client');
fopen(t)
pause(2);
file_as_char = fileread('YourFile.evt');
fwrite(t, file_as_char);

On the receiving side

data = fread(t);

thanks so much, how can i do to solve this problem ? i dont speak english sorry my way to write.

But at this stage I have to ask you how serious your project is, how large are the files that you need to transfer, and why you need to manage file transfer from MATLAB. Because writing a solid/stable client-server system is complicated.

For a small project, I would play with TCPIP etc, because it is "fun" to learn a bit how to deal with these things. If I had to build a solid/stable solution though, I would install an FTP server or a Web server, or anything which supports protocols for transferring files, and I would use this from MATLAB. If one machine had an FTP server for example, I would use

http://www.mathworks.com/help/matlab/ref/ftp-class.html

Then I would just test the presence of new files, or use TCPIP for signaling/synchronizing transfers, and let the FTP client/server, WGET, etc, manage file transfers properly.

the truth is that I have to transfer files constantly from multiple computers to a principal , through dial up , I wanted to test how to pass files with tcpip because I thought it would be equal to the modem 232 , if not, could you help me do it ? I call specific numbers modem and transfer the files . if you would be a tremendous help . this is my mail [e-mail]

[Walter Roberson]

The techniques you would use for tcp are not the same as what you would use for a modem.

When you are using a modem, you should prefer to use a modem file transfer mechanism that has already well tested. For example use Kermit, or zmodem, both of which can deal with transferring multiple files. If you are using MS Windows, you could consider using hyperterminal

-.-' my god ,. please can you please help me ,. i really need do that ,. is my tesis. i really need your help. this is my email [e-mail] i dont have any idea to star

[Cedric]

But the first thing that you need to clarify is the context. Is this file transfer something that you need to do only once, how many files, how large they are roughly, why MATLAB, etc.

[Vanessa ricardo]

what I need is: I have several computers connected through dial up modem rs232 to a private telephone line , each modem has its number this network already exists , I wanna call the specific number and have a program that responds to my call . I have three pcs in two of them constantly .evt files stored in a folder called events. what I want is that in the third pc main constantmente these folders are synchronized automatically , that is like a cloud.

use matlab because is the program that my university want. if you give me a email i can explain better. sorry the english again.

[Walter Roberson]

Is this to solve a practical problem, or is it a university assignment? If it is to solve a practical problem, then do not use MATLAB for this: use one of the existing tools such as kermit or hyperterm.
