Hi,
I was using the net/ssh library in my code ro ssh to a particular
machine.
But I found that the ssh library goes directly to the shell prompt and
executes the commands. net/ssh uses the ssh2 protocol internally, I also
tried using ssh1
but with no success.
Initially the prompt that appears should have been something like ">>>>"
but
in my case after running the script it goes directly to the shell prompt
"$" by-passing the cli prompt.
a. Why does this behaviour take place??
b. Is there a way to go to the initial cli prompt ??
-P

From `ri Net::SSH`
Net::SSH.start("host", "user", :password => "password") do |ssh|
result = ssh.exec!("ls -l")
puts result
end
Sample of my own stuff...
require 'rubygems'
require 'net/ssh'
server = "acid"
user = "jayeola"
Net::SSH.start(server, user) do |x|
cmd2 = x.exec!("test -d /proc && echo \"OK\"").strip
p cmd2
if cmd2 != "OK"
p "no proc found"
else
p "got proc"
end
cmd3 = x.exec!("test -f /proc/partitions && echo \"OK\"")
cmd4 = x.exec!("test -f /proc/diskstats && echo \"OK\"")
end
I'm using this library and it doesn't give me a prompt at all but runs
the code as required. How are you using it?

Hi John,
I am using it the same way as you are using. The problem lies
when the initial prompt that is needed gets by-passed when I use the
net/ssh module. I have been usng the net/telnet module initially, where
I get the appropriate prompt on logging in. ie. ">>>". and the shell
prompt is "$" which arises when i do a "!" on the initial prompt.
Telnet works fine, but i am exercising the usage of connecting to the
box thru ssh. So here it by-passes the initial prompt which telnet
module does not.
As telnet looks for a given prompt while logging in, does ssh have such
a prompt?
Also I guess the net/ssh module in ruby creates a instance of the shell
and executed the commands to be executed on that shell rather than
connecting to the actual machine.

session.exec!("some command") runs that command on the remote server. You'll have to use another method to gain a shell session. Have a look at `ri Net::SSH` or use `gem_server` and fire up a browser with localhost:8808, (geddit ?). There __is__ a way to get a shell but I've forgotten what it is. Perhaps the gem termios?
