I need scp to authenticate via the .shosts in my root directory. So far I have ssh working to authenticate but scp for some reason requests a passphrase. This is a copy of the output from scp -v to the machine I want to authenticate with... # scp -v somefile somewhere:/tmp > errors.txt Executing: host somewhere, user (unspecified), command scp -v -t /tmp SSH Version 1.2.27 [i586-unknown-linux], protocol version 1.5. Compiled with RSAREF. : Reading configuration data /root/.ssh/config : ssh_connect: getuid 0 geteuid 0 anon 0 : Connecting to somewhere [*.*.*.*] port 22. : Allocated local port 1022. : Connection established. : Remote protocol version 1.99, remote software version OpenSSH_2.5.2p2 : Waiting for server public key. : Received server public key (768 bits) and host key (1024 bits). : Host 'somewhere' is known and matches the host key. : Initializing random; seed file /root/.ssh/random_seed : IDEA not supported, using 3des instead. : Encryption type: 3des : Sent encrypted session key. : Installing crc compensation attack detector. : Received encrypted confirmation. : No agent. : Trying RSA authentication with key 'root@----' : Received RSA challenge from server.
