How to automate secure FTP password

[Steve_615]

Hi,

Does anyone have ideas on how to automate an SFTP login, so that I do not get prompted for a password. We are trying to script this SFTP transfer and it always stops at the prompt for the login password.

Thanks for any of your help

Are you using public key authentication?

If you're public key has been put in the target's ~/.ssh/authorized_keys file, test it out with this syntax. If there is a problem, the verbose output should help with troubleshooting.

sftp -v -o preferredauthentications=publickey hotname

If you haven't setup a key, search the forums for "ssh authorized keys". There are plenty of threads out there to show you how to set it up.

hope this helps,

I've set up the keys and did not put in a passphrase (just hit enter) and I still get prompted for a password. Getting very frustrating.

Can the problem be on the remote server side?? I am SFTP'ing from an HP-UX 11.i server to a Linux 2.6.9 server. Is this something that should work??

All your help has been appreciated.

I may try to test this HP to HP just to see if I can get it working.

What about the ssh_config file??? Can this be the source of the problem?

Thanks,

Steve

Problem could be incorrect permissions on $HOME/.ssh directory and files on the Linux (server) side.

Make sure that directory $HOME/.ssh and all files in it, on the Linux box, are not group/world writable.

Also check /etc/ssh/sshd_config on the Linux side (location of sshd_config could be different depending on your distribution) and make sure the following lines are set correctly.

PubkeyAuthentication yes
AuthorizedKeysFile .ssh/authorized_keys
Subsystem sftp /usr/libexec/openssh/sftp-server

If you modify sshd_config don't forget to restart sshd.
