Get your binaries from here<\/a>.<\/p>\n\n\n\n

1.On your source host, generate a ssh key pair (private and public) : ssh-keygen<\/strong><\/p>\n\n\n\n

2.Copy your public key on your target host<\/p>\n\n\n\n

3.Add your public key to authorized keys on your target host : cat id_rsa.pub >> .ssh\/authorized_keys<\/strong><\/p>\n\n\n\n

And you should be done (sftp and ssh examples below).<\/p>\n\n\n\n

SFTP from your source to target host using your private key : sftp –ip=192.168.1.126 –username=jeedom –privatekey=%homepath%\\.ssh\\id_rsa –local_filename=readme.md –command=put –debug=true<\/strong><\/p>\n\n\n\n

SSH from your source to target host using your private key : ssh –ip=192.168.1.126 –username=jeedom –privatekey=%homepath%\\.ssh\\id_rsa –debug=true<\/strong><\/p>\n\n\n\n

<\/p>\n\n\n\n

Note1 : libssh2 will accept private keys in both format (RSA PRIVATE KEY or OPENSSH PRIVATE KEY)<\/p>\n\n\n\n

Note2 : libssh2 will accept public keys in OpenSSH format only (but will manage to derive the public key from the private key if you dont provide the public key)<\/p>\n\n\n\n

Note3 : on linux, you can convert a public key generated by OpenSSL (in PEM format) to OpenSSH<\/p>\n\n\n\n

ssh-keygen -i -m PKCS8 -f public.pem > public.pub<\/code><\/pre>\n\n\n\n
Note4:<\/p>\n\n\n\n
You can push your public key like below:<\/p>\n\n\n\n
ssh –ip=192.168.1.126 –username=jeedom –password=Mjeedom96 –put –filename=id_rsa.pub<\/strong><\/p>\n\n\n\n
ssh –ip=192.168.1.126 –username=jeedom –password=Mjeedom96 –delay=250 –command=\u00a0\u00bbcat id_rsa.pub >> .ssh\/authorized_keys\u00a0\u00bb<\/strong><\/p>\n\n\n\n
or (pipe in)<\/p>\n\n\n\n
echo \u00ab\u00a0cat id_rsa.pub >> .ssh\/authorized_keys\u00a0\u00bb | ssh –ip=192.168.1.126 –username=jeedom –password=Mjeedom96<\/strong><\/p>\n\n\n\n
Note5: don’t forget to chmod 700 * in .ssh folder (and check cat \/var\/log\/auth.log in case you get access denied)<\/p>\n\n\n\n
Note6 : if still not working, check your \/etc\/ssh\/sshd_config for the below enabled parameters<\/p>\n\n\n\n
