How to Mock Net::SSH Authentication Scheme

[Tiago Cardoso]

I'm having some problems setting my tests up to test an ssh client connection. Basically I'm setting a kind of "SSH Server" on another process, binding it to a port, and telling my connection client to connect to that port. The client uses Net::SSH. Problem is, when it binds, it expects the whole SSH authentication protocol messages back and forth (SSH Version, key exchange, bla bla bla...). I would like either to replicate that behaviour on my server (quite difficult, haven't seen that anywhere) or at least mock the Net::SSH authentication scheme so that it bypasses it and uses an unencrypted channel (just for testing purposes, as stated).

I know this is not the best channel to discuss this, but I haven't found any net-ssh discussion group, and since capistrano does use Net::SSH extensively and tests its code, I would like to know if somebody has ever stumbled on this issue, maybe there is a best solution for this.

Hi Tiago,

I can't imagine why you aren't just using SSH normally. I can't say I've ever had the problem. In cases where I've needed to test something, I have started opensshd in another process in a chroot jail, and examined the filesystem changes from outside.

Using SSH without authentication isn't really using SSH.
