Error running remote control

juanramb · November 13, 2020, 11:37am

What is the problem you are having with rclone?

Cannot run a remote control rc command against a rclone server. I am trying a simple ls command against rclone container local files

What is your rclone version (output from `rclone version`)

1.53.2

Which OS you are using and how many bits (eg Windows 7, 64 bit)

Linux 64bit docker

Which cloud storage system are you using? (eg Google Drive)

Local files

The command you were trying to run (eg `rclone copy /tmp remote:tmp`)

Server:

hello and welcome to the forum,

not an expert in docket.
perhaps use quotes to surround the command
command="ls -a /.cache/"

piscator · November 13, 2020, 3:06pm

I think @asdffdsa is right: you need the quotes.

I am also using docker and have a few tips.

If you start the container with docker run --name=rclone <your-settings>, you can play around with rclone commands in a prompt with docker exec -it rclone /bin/sh. Makes playing a lot easier.
For the 2nd command you run, it might be more practical to use docker exec instead of docker run (exec uses an existing container and run starts a new container). So, the port 5572 is local (and not in another container). It is also faster and uses less resources.

juanramb · November 13, 2020, 3:25pm

Yes, running exec inside rclone server it works as expected. But I need to launch remote control from a different container

juanramb · November 13, 2020, 3:28pm

@asdffdsa In this case it is rc syntax you have to use command=yourcommand and -a commandparams, as it is in the documentation https://rclone.org/rc/#core-command

Came across to test core/command today, but it failed. My rclone is native, not with a docker container. Other than that, everything seems pretty much the same as @juanramb.

Here are the results when I run example commands in doc.

$ rclone rc core/command command=ls -a myremote:/ -o max-depth=1 --rc-addr=127.0.0.1:5599 -vv

Different representation with command/arg/opt gets the same result.

rclone rc core/command -a ls -a myremote:/ -o max-depth=1 --rc-addr=127.0.0.1:5599

According to debug log, it seems nothing to do with quotes as args are successfully parsed.

Could someone test and give working examples? Thanks!

Still experiencing the same failure in v1.53.3.

spicypixel · December 26, 2020, 1:36pm

Experiencing the same issue when trying to use the official docker image and using rclone to rc to it to execute commands.

wiserain · January 10, 2021, 7:58am

Issue is filed and fixing now? https://github.com/rclone/rclone/issues/4914
