Hi,

I'm running into a problem with scp on both my Fedora 2 and RedHat
Enterprise Linux 3 machines. I have found this problem discussed here
previously but it was never clearly resolved.

When I try to copy files to/from my redhat machines to a server running
3.2.0 SSH Secure Shell (non-commercial) I get the following error:

scp: warning: Executing scp1.
scp: FATAL: Executing ssh1 in compatibility mode failed (Check that scp1
is in your PATH).

However, ssh to the same remote machine works. Also I can scp to other
linux machines. The verbose output from the functional and non-functional
scp sessions are attached below.

Any help will be greatly appreciated.

Thanks,

MikeX

Additional information:

These are the ssh packages which are installed:
[mikeg@nyasa mikeg]$ rpm -qa | grep ssh
openssh-clients-3.6.1p2-33.30.1
openssh-server-3.6.1p2-33.30.1
openssh-askpass-gnome-3.6.1p2-33.30.1
openssh-3.6.1p2-33.30.1
openssh-askpass-3.6.1p2-33.30.1

This is output from whereis:
[mikeg@nyasa mikeg]$ whereis scp1
scp1:
[mikeg@nyasa mikeg]$ whereis scp2
scp2:
[mikeg@nyasa mikeg]$ whereis scp
scp: /usr/bin/scp /usr/share/man/man1/scp.1.gz

Here is the debug info:
