Hi ,

i´m having a small big problem 🙂

I´m using net-ssh lib to authenticate, and execute commands remotely  
in a rails application.

The problem is that i´m getting the exception  
“could not settle on kex algorithm” when try to open a session, this  
happens  
when i execute the code in the rails context.

When i execute the code by command line, it runs well.

My environment has:  
net-ssh (1.1.0)  
rails (1.2.1)  
ruby 1.8.4

I believe that i have all the lib/bindings installed for ruby.  
Can anyone help!?

Thanks,  
André
