Net/ssh telnet set port 119 (nntp)

Ruby
#1

Following the API at:

http://rubydoc.info/gems/net-ssh-telnet/0.0.2/frames

I want to login to leafnode with something like:

s = Net::SSH::Telnet.new(:host => localhost,:port => 119)

here’s what I have so far, though:

[email protected]:~/ruby/telnet$
[email protected]:~/ruby/telnet$ ruby telnet.rb
hello
telnet.rb:8:in `’: uninitialized constant Net::SSH::Telnet

[email protected]:~/ruby/telnet$ nl telnet.rb
1 require “rubygems”
2 require “net/ssh”

 3  puts "hello"


 4  s = Net::SSH::Telnet.new(
 5          "Dump_log" => "/dev/stdout",
 6          "Host" => "127.0.0.1:119",
 7  )

 8  puts "Logged in"
 9  puts s.cmd("echo hello")

10  put "started"

I’ve tried various ways of setting the port, but can’t figure it out.
How do you set the port?

thanks,

Ruby cookbook to the rescue, 14.9 “being a telnet client”:

 5  webserver.cmd("GET / HTTP/1.1\nHost: www.oreilly.com\n") do |c|

just need to login to leafnode now :slight_smile:

Because you’re not using the sample code?

4 s = Net::SSH::Telnet.new(
5 “Dump_log” => “/dev/stdout”,
6 “Session” => ssh
7 )

Where have you defined the ‘ssh’ for “Session”? Go back and look at
the gem’s sample code.

Pardon, I don’t understand:

http://rubydoc.info/gems/net-ssh-telnet/0.0.2/frames

example 1:

s = Net::SSH::Telnet.new(
“Dump_log” => “/dev/stdout”,
“Session” => ssh
)
puts “Logged in”
p s.cmd(“echo hello”)

That’s not my code, that’s the sample code. What I’m asking is why the
sample code, when copied, pasted, gives errors as so:

ah, ok. I thought I’d tried that, but apparently not. There’s no
login,
I just would like to pass some commands to leafnode and get the
response.

Am I not getting the output correctly?

Really? Here’s what I see in Example 1 –

Example 1 - pass existing Net::SSH::Session object

ssh = Net::SSH.start(“127.0.0.1”,
:username=>“test123”,
:password=>“pass456”
)
s = Net::SSH::Telnet.new(
“Dump_log” => “/dev/stdout”,
“Session” => ssh
)
puts “Logged in”
p s.cmd(“echo hello”)

What I’m asking is why the
sample code, when copied, pasted, gives errors as so:

ssh.rb:10:in <main>': undefined local variable or methodssh’

Because you didn’t copy all of it, and the variable ‘ssh’ in your broken
abbreviated test isn’t defined.

Just what the error message says, unsurprisingly :slight_smile:

you’re right, when I read that last night I was a bit tired.

I’m trying to look at the corresponding API for “non-ssh” telnet, to
figure out how to login to leafnode and get the output printed to the
screen. I just get timeouts so far:

In fact, it doesn’t even seem to be “logging in” since that put never
executes. Am I using the right API? If so, how do I get the response
which “telnet localhost nntp” brings up in the terminal?

thanks,
