Hi,
I'm trying to scp some files between two remote servers. I use a
command like:
scp -i ssh_key root@comp1:/path1/file1 root@comp2:/path2/

This returns the error "Host key verification failed" and then I lose
the connection. Running in verbose mode tells me that the verification
fails for the destination server (comp2).

However, I know that the host key that I specify is correct for both
servers. I can successfully:
ssh -i ssh_key root@comp1
ssh -i ssh_key root@comp2

My ssh key has a passphrase and I use ssh-keychain (an OSX app) to
manage the passphrases for my sessions.

Any ideas what I'm doing wrong?

Cheers,
complext

The "host key" is not the key you're using for client authentication.
Check /etc/ssh/ssh_known_hosts or ~/.ssh/known_hosts for a mismatched key
labelled with the server hostname and/or address.
