Yuo can use it just fine for the SSH case, I suppose. But I’m not sure that telnet is a supported protocol – it would be a coincidence if it were.
Fabric is really just a tool to automate the execution of commands over SSH. Note that this article was written in 2009 and that Fabric has moved forward a fair bit since then.

What would the possibility be of using fabric for router config changes using ssh or telnet access ?

The article was written for the 0.1 series of Fabric. What you have installed is a 0.9 series version, which has an overhauled command line interface.

Thanks for the article. I have to tell you that “hab list” doesn’t work for me, it should be “fab –list”.

Hi, I think I’m right in saying this is for the 0.1 version of Fabric not the 0.9 whose release is fairly imminent? Looking for more examples of fabfiles written with the new API! :)

@Alex – you have misinterpreted the interpretation of the GPL – the link you posted refers directly to the JNI or java native interface, a way of binding with machine code libraries through java. That is linking, not running bytecode on an interepter.

For the record – as far as I know Fabric uses paramiko, which is pure python. :)

@Alex G

That’s an interesting question. I don’t think people normally release fabfiles in a way that would otherwise be covered by the GPL, but the answer is no; fabfiles are not covered by the GPL that covers Fabric itself. I consider it an implementation detail that Fabric loads the fabfile into the same interpretor instance.

That is what I intended when I licensed Fabric under the GPL.

If someone more knowledgeable on the legal details insists that Fabric is incompatible with its intended use, then I will handle it by fixing the license, rather than the program.

so here’s what I’m curious about… since fab is GPL and fabfiles are mostly a bunch of “dynamically linked calls” to fab’s methods, does that mean you must release your fabfiles? :)

A consequence is that if you choose to use GPL’d Perl modules or Java classes in your program, you must release the program in a GPL-compatible way, regardless of the license used in the Perl or Java interpreter that the combined Perl or Java program will run on.

perl and java is just an example.
