telnet binary file transfer

[Per Akesson]

I'm using telnet for transfer of binary files.

Though it seems that telnet interprets the 0xff as delete character.

On the client side, the byte following a 0xff byte, is stripped.

Is it possible to transfer binary files "cleanly" with telnet ?

If so, how do I do ?

thanks in advance

Yes, if you use C-Kermit as your Telnet client:

not really advisable, that is what ftp is for :-)
(stuff about 0xff offset deleted)

Well if you *have* to do this and you don't have another option
like rcp or (preferably) scp (ssh copy) you could uuencode the file first.

Small normal files:

cat -u - foobar.c - | telnet foo.com | cat >>/usr/tmp/foobar.c <CTRL-D>

UUencoded:

cat -u - foobar.uu - | telnet foo.com | cat <CTRL-D>
