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.

Telnet works fine, but i am exercising the usage of connecting to the
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?
