Hi all,
I’m using Ruby about 3-4 mounts. Now, i want to make a project about
network devices with SNMP.
But, until this time; i haven’t used rubyonrails yet.
Yesterday (i hope) i’ve installed rubyonrails. And i made some steps
like that:
rails /home/student/new_directory
and i copy a script in it like:
#!/usr/bin/ruby
require ‘snmp’
ifTable_columns =
[“ifIndex”, “ifDescr”, “ifInOctets”, “ifOutOctets”]
SNMP::Manager.open(:Host => ‘localhost’) do |manager|
manager.walk(ifTable_columns) do |row|
row.each { |vb| print “\t#{vb.value}” }
puts
end
end
But it tells me;
`require’: no such file to load – snmp (LoadError)
I tried to fix this but i couldn’t do anything.
So i gave up to do it with rubyonrails; and installed s2nmp
(http://members.at.infoseek.co.jp/m6809/ex_get.html).
This time; i tried to run this script like: Ruby example.rb 10.0.0.2
(i couldn’t find an ip address to make excercises so i tried to use my
adsl router: 10.0.0.2)
Usage: ruby getsysdsc.rb
require ‘socket’
require ‘s2nmp’
host=ARGV.shift
s=SNMP.new(host)
sts=s.get(“public”,[“1.3.6.1.2.1.1.1.0”])
if sts then
p s.vars
else
print “TIMEOUT.”
end
It tells me:
/usr/lib/ruby/1.8/s2nmp.rb:267:in recv': Connection refused - recvfrom(2) (Errno::ECONNREFUSED) from /usr/lib/ruby/1.8/s2nmp.rb:267:in
get’
from example.rb:10
Can you give me any ideas or advices? Plus; i haven’t decide to make it
with s2nmp or rubyonrails.
Best Regards,
Esravan Rolda.
