Problem I am having

The librenms + oxidized integration works without any problem. Everything is being backed up, and I have a local copy and a copy on azure git. Beautiful!

My problem is when I try to use oxs.

When the device has telnet enabled, with this command I can pull the config: oxs 'sh run'

But I got the following error every time I try to do the same command on devices that has only ssh enable or when I change the configuration only to use ssh:

/var/lib/gems/3.0.0/gems/oxidized-script-0.6.0/lib/oxidized/script/script.rb:113:in connect': unable to connect (Oxidized::Script::NoConnection)

from /usr/local/bin/oxs:25:in <main>'

And to be fair, I want to make ssh work because is way more secure.

Does anyone have a similar problem? Is there a fix for it?

Thank you

I am having the exact same issue, any help or guidance how we can fix this will be much appreciated.

For people having this issue:

I had same problem, after debugging, looks like the problem is the version of the slop dependency is mismatching with what installed from oxidized.

To workaround this:

1. Uninstall current oxidized script and also the oxidized 0.26 it installed.
2. git clone the current master branch.
3. under the root folder, do "gem build" it will creates FILENAME..gem file to install.
4. do gem install FILENAME.gem

That should fix the issue until there is a new oxidized-script version release.
