Synapse: TFTP over TCP instead of UDP?

I'm writing client and server console mode programs that need to
transfer files.

I'm looking at the synapse (trunk) tftp client+server code, but can't
seem to find a way to switch the protocol from UDP to TCP.

Any suggestions?
Thanks,
BigChimp

Why Tftp and not Ftp ? Tftp is an udp protocol, Ftp is a tcp protocol.

Hi JP,

1. TFTP is simple, I don't really need anything else (multiple file
support etc). Synapse has a TFTP client and server in its units
2. Yes, TFTP is UDP by default but apparently can also work over TCP.

That said, I don't mind another way of transferring files keeping in
my mind that I'm writing both client and server and don't want it too
bloated/complicated

Also, I might drop the TCP preference - might be easiest to do. Still,
I would like to know if it is possible with Synapse.

there are a number of demos at http://synapse.ararat.cz/files/contrib
with the most useful of them to be
http://synapse.ararat.cz/files/contrib/sftp.zip and
http://synapse.ararat.cz/files/contrib/ftpserv.zip as far as I can see
the second one has a very simple implementation to get you started.

Ehm yes, taazz, but isn't sftp secure ftp and the ftpserv is an FTP
example.

I've already got code using Synapse's TFTP class by following their
documentation. Of course, it could well be buggy/incomplete but that's
a different matter

yes sftp is secure ftp probably requires ssl or some other type of
encryption and I think is a client sample. ftoserv is an ftp server
example and it is multi threaded as well so I think it is the perfect
starting point if you want and ftp client sample there is the ftpdemo
to get you started. I think that with those 2 you have your file
server/client in no time.

As always I haven't code any net applications professionally except
from light tests on the library so I might be off in my assumptions.

Ok, just to reiterate: I already have client/server code using tftp;
just looking if it can be sent over tcp instead of udp... If not, too
bad.

Don't really see the point of messing with ftp or sftp at this point,
but thanks for the info.
