lftp ignores ssl key-file when specified in batchfile

[JohnLelii-CMCST]

EXEC:
lftp -f batchfile

You can see the specified keyfile is never attempted with the remote server. Also behaves the same way with an interactive session and providing the same commands in sequence. A workaround is to sym link the ~/.ssh/id_rsa file to the specified keyfile.

Please confirm if this is resolved in a newer version. thanks.

You have to specify the ssh key file in the sftp:connect-program setting like this:
set sftp:connect-program "ssh -x -i key-file"
