zmodem upload with rz
Ken Williams
2.4/ext3) supports large files but it dies at 2 gigs. anyone know how
to get rz compiled for large files? I use SecureCRT under WinXP, maybe
its that which has a problem sending the large files?

I didn't even realise zmodem still existed. Haven't used that in over 15
years, I think.
Ayway, why not use scp, or even ftp ? There is a graphical client for scp
under windows, called WinSCP. Works ok, if a bit slow.
depending on your circonstances, a SMB share could do the trick.
If you absolutely, absolutely need to use zmodem, I'm sorry about wasting
your time. Good luck.

"it dies"... with exactly what error message? "linux 2.4" is
relatively meaningless - which distribution and release, and which
kernel version within that release? If it's a custom compile, what
options did you specify?

Lessee, a 2 gig file over a 56k modem is going to take... how many
hours? There isn't anything in the protocol that restricts size,
and as long as source and destination operating systems allow byte
serial access to the file, the program itself shouldn't have a
problem.

Try using TCP/IP and the file transfer protocol.

The protocol is older - the "current" spec is from mid 1988. As far
as Linux goes, it's part of the 'lrzsz-0.12.*' package, and while
0.12.20 is from ~1999, it's still included in some current
distributions.
[compton ~]$ zgrep lrzsz rpms.fedora11-x86.gz | cut -c42-

[compton ~]$

Well, as far as I remember WIN XP supports up to 4 gbyte files, maybe more.
FAT 32 is restricted to some 4 gb, whysoever. So 2 gb should be no problem
from that aspect.
Maybe there is a timeout? How long does it take you to download 2 gb?
ZModem, well that is quite some time ago. That was one of the very few
programs I ever bought. That was when I used DOS on my pc (my very first
ond, 286/12 with 1 (!) mb ram, a very sturdy machine, I used it some 6
years). I bought it just about a year before it was available for free (for
my at that time favorite point program CrossPoint). Cost me some 40 DM
(about 20 EUR). It was very reliable, just worked out of the box and
everybody was happy with it.
Ever thought about switching over to some cable modem or something like
that? My first modem was one with 2400 bit/second. When I downloaded mails
I could read them on the screen during the download, quite handy ;-) Some
two years later we got a 9600 bit/second modem which was very fine, it was
even capable of a 14400 fax protocol. But several years we stepped over to
ISDN and now here in The Netherlands I am connected via a cable modem,
which is absolutely fantastic.
I did my first steps with networking with help of some friends who showed me
how that worked under Linux (IIRC that was SuSE 6.0 or something like that,
maybe even one version earlier). Very logical. Then with MS Windows, why
the heck do they use other terms for the same things and why are their
descriptions for some dummy like me not really good to understand?
But for several reasons we went on using WIN for some years. When we
switched over to Linux, I admit that I just forced my family to do so
because I formatted the hdd and installed Linux there, that all got much
easier to understand.
Sorry that I cannot really help. Somehow a bit oldfashioned this zmodem
issue, but on the other hand: We all know that not only well funded people
use the net. And I am absolutely sure that in that world outside there are
still a lot of modem users - for them zmodem is very useful, since it is
one of the finest protocols ever.
