Hi,

I had a gateway on a RedHat box, but now that their support for the
mainstream version has been discontinued I switched to OpenBSD v3.4.

I used to upload a lot of files from my Windows box to my RedHat
gateway using ZMODEM in SecureCRT over an SSH2 connection and never
had any problems. But now with the lrzsz package that comes with
OpenBSD, when I receive files with the lrz command, the transfer
hangs at the end of the file, and it seems stuck forever.

If the file is small (a few kilobytes), everything goes fine. But for
larger files, when the transfer reaches 100%, the dialog box stays
open forever in SecureCRT and nothing happens. Even if I press
"Cancel" the file gets deleted and the shell isn't responding
afterwards (I have to close the connection and reconnect).

If I give the -qeb options (quiet / escape chars / binary) to lrz, I
get the same behavior. I also tried running lrz with lots of -v to
see what the error was, and all I saw was a timeout error every 10
second at the end of the log. It seems that lrz never gets the ZFIN
command sent by SecureCRT, which it does when the file is smaller.

With the same SecureCRT client and the same lrzsz version on RedHat
(installed with RPM), I never had any problems. Also, the lsz program
(Send ZMODEM) on OpenBSD works fine too, even with large files.

Anyone has an idea about this?

I searched the web a lot, and my problem seems pretty rare. I sure
could use another method for transfering files, but ZMODEM is really
convenient since it is fully integrated with my SSH client...
