I have 2 systems I work with that are daisy chained. System A is what I have to connect to initially, then I ssh into system B to run commands to view status of services and other things. I work doing field support on these systems and have no way to change the way they work in regards to creating APIs or how we connect to them.
What I want to do is have a ruby script that can get into system B to run some commands and then pass the output from those commands back into my laptop automatically.
I can use ruby gem net/ssh to get into system A and run commands but I cannot figure out how to ssh into system B after I am in system A. This is what I have right now.
Net::SSH.start('123.456.78.9', 'username', password: 'password') do |ssh|
# some how ssh into system b
end
I tried just ssh.exec! "ssh 123.456.78.30" but that does not work. I tried nesting another Net::SSH.start call but that doesn't work either.
Finally, I'd also like to scp files from system B back to a /tmp folder in system A but I can't get that to work either. That's a whole other thing but if anyone has any advice on that I would appreciate it.
Also just a note that the password I put in the script isn't the actual password. When ruby net/ssh runs and it hits the wrong password the shell prompts for a password and I put the actual one in. Maybe I can do that a less hacky way but right now it's not the priority.
