Security

Be aware of the security implications of running this node. Behind the scenes javascript is executing the lftp binary. The lftp binary can execute other processes on the host system indirectly. Only run this if you are sure of your environment and understand the implications.

node-red-contrib-lftp's Issues

Error: spawn lftp ENOENT

Running Node-RED version: v0.20.5, Node.js version: v10.23.1, Linux 4.14.138 arm LE
This embedded so I don't have control over the versions.
Manually installed lftp and it's dependencies.
Getting Error: spawn lftp ENOENT on any command.

Support "site quota" or abitrary command execution

I have a ftp server where some stuff is automatically uploaded to.
I started to use node-red-contrib-lftp and it is working great so far.
Now I want to monitor if the ftp server is getting full.
The server I am using supports the "site quota" command.

ftp> site
(arguments to SITE command) quota
200 Available: 0 (0MiB) Limit: 30737596416 (29314MiB)
ftp> 221 Goodbye.

I was under the impression that I can just set msg.operation to "site quota", but apparently this does not work - only the already supported commands can be sent.

Two solutions come to my mind:

1. Implement "site quota" as a native command.
2. Implement a mechanism that allows it to pass-through arbitrary commands to the ftp server and feed back the result to node-red.

What do you think?
