I have a Mandrake system that I use to connect to one of my customers. I
generated keys using "ssh-keygen -t dsa" on my mandrake box. I then
sftp'd into my customer's and transferred the id_dsa.pub file renaming
it authorized_keys. I then exited out and retried the sftp. Everything
works great. I get in immediately without being asked any passwords.
When I try to use "scp" to transfer a file into my customer's machine,
it always asks me for the password for the use on the customer's
machine. After entering the password, I'm in. But I would like to
execute the scp command from a script without being asked to enter
anything.
Why does sftp get in and scp does not? Here is the output of a "scp
-vvv" command into the customer's machine:
Executing: program /usr/bin/ssh host sftp.example.com, user XXXXX,
command scp -v -t spool
