Help requested - Application to use an IP interface
|
|
|
| Folks,
I am writing an application that interfaces with a machine that has both
serial and IP communications.
The application sends and receives text strings.
I have written it using the serial interface, because I have easy access to
it, but when it is used for real, it needs to send and receive the same
strings to an IP address. I have never done this kind of programming before
(the IP interface).
Given the IP address of the machine (and possibly the address of a gateway
to it), can anybody give me any pointers of where to find what I need, and
if somebody could give me a short and simple working example, it would be
like a preview of the next world (Heaven, I hope!)
Typically, I will send strings like
> sendLog
.... and write the returned log intom a buffer.
Thanks (with bated breath)
Mike.

1st) This is a good (and small) book to get you started:
"Pocket Guide to TCP/IP Sockets" (C Version) ISBN 1558606866
2nd) Inspect the source code for common network utilities, such as
telnet, rsh, rcp, etc. (Skip anything related to authentication and
cryptography, at least for now.)
3rd) Web search for "socket tutorials", etc.
4th) Standard advice: post again in a newsgroup or mailing list
dedicated to the platform/OS/environment etc. you are using for this
project, and/or to network programming. (comp.protocols.tcp-ip,
comp.os.???)

| Many thanks to both who responded. I'll order the books and see where we go
from there.

| Folks,
I already replied. I don't know why it didn't get posted.
Just a note to say thanks to my two respondants, and to ask where I can
examine the source code for "common network utilities, such as
telnet, rsh, rcp, etc.", as suggested by Roberto Waltman.
Thanks and Regards,
Mike.

A full Linux distribution (I think) includes sources of the modules
for which you're looking - you can download or buy a CD. Prepare to
spend a _lot_ of time reading. I'm not sure, but think sources may
also accompany BSD distributions.
If you can't find 'em or lack resources, e-mail me and I'll send one
of my ancient Linux CDs.
