no match and scp/sftp not working. Is the no match causing my problem? how to resolve
aa
Per subject, I cant scp nor sftp. I have a SuSe 7.2 2.4.4 kernel
with OpenSSH_2.9p1, SSH protocols 1.5/2.0, OpenSSL, and Freebsd
sshd version OpenSSH_2.3.0 gr...@FreeBSD.org 20010321. Please help
me troubleshoot what causes my broken pipe. Thanks in advance.

No.

What is this? It looks like the command "scp" is running "gcc" instead,
or else your .bashrc file is doing it and/or producing output, which it
must not. See:
http://www.snailbook.com/faq/sftp-corruption.auto.html
Slightly different context, but same problem.

no. this is just a debug message.
>debug1: EOF received for stdin.
perhaps scp is not installed on the server, or not
in the default path.

Thank you! Thank you! That cured it, I took out the echo I came in from
.bashrc, this was my debugging printstatment :), and didn't know it
was causing such a big issue for me.
BTW, for the responder who had suggested I need a an scp on the serverside?
I do not know if I have one running on freebsd or not, as I thought
it is part of the sshd which creates a subprocess and subprotocol for file
transfer. Also I can not find a scp client nor scpd (server?) on my freebsd.
For now, I am able to transfer the files between the linux and freebsd.
I wish I know a tool I can verify the transfer is secure (encrypted), likewise
even if I was not using ssh, I wish I have a tool to view/capture and see the
bits going trough in-between. I have heard of protocol analyzers, is there
a cheap one that comes with linux or freebsd? Thanks.

Yes, and it runs scp in that process to talk to the client-side scp.

It's the same program, invoked with the -t or -f options to make receive
or send files as needed. But it must be there, or your file transfers
would not be working.

"tcpdump" -- if it isn't in your FreeBSD installation, you can get the
source and compile it yourself. You can certainly see that the SSH
traffic does not contain plain text as opposed to Telnet, for example, but
it cannot let you verify that it is "secure."
