I'm using lftp to send files to an SFTP server, but I don't how to connect with key and passphrase.
So in sftp
, I can do this:
sftp -i .ssh/id_rsa.mykey [email protected]
Enter passphrase for key '.ssh/id_rsa.mykey': my passphrase here
So, how can I use lftp with this connection method?
An answer based off Jean-Luc Boss's and wiak's, but a bit more explicit:
To connect to a server, lftp
uses an ssh
command, by default ssh -a -x
. It doesn't have an explicit option for changing the keyfile to use, but as you note, ssh
does, so we just need to set lftp
to connect using ssh -a -x -i <keyfile>
before it connects.
You can do this in a few ways:
If you're using lftp's interactive command line, run the following command before you connect:
set sftp:connect-program "ssh -a -x -i <keyfile>"
If you're specifying a bunch of commands to lftp
using -c
, just add that set command to the start of your command sequence:
lftp -c 'set sftp:connect-program "ssh -a -x -i <keyfile>"; connect sftp://[email protected]; mirror -eR files; ...'
If you always going to want to use the same key, just add that set ...
line from the first bullet to your ~/.lftprc
file (or one of the other configuration file options listed in man lftp
).
