SFTP setup

[Michael Murphy_2]

Hello - in the past when setting up on-way sftp to a remote servers we always exchanged keys. What is the minimal that is required for a one-way send to a remote machine - do i generate a key and send to them to put in authorized_keys - or vice-versa - or both? Do both sides need a .ssh dir? thanks

The key need to be generated in your own site then append it to the remote site (authorized_keys). You can send or receive files from your site to remote one.

Hi,

Note keys are required only for password less authentication. If it is normal sftp keys are not required.

You need to generate the public using ssh-keygen and append it on remote server $HOME/.ssh/autherized_keys file.

One way is enough. If you want to achieve password less login from both do the vice-versa also.

>>Do both sides need a .ssh dir<<<

yes. when you generate the key on source server this dir will be created. On remote server also you need this dir to put the authorized_keys file
