Forum: Ruby ruby-snmp annoying problem :(

Simple script (Should set Integer=1 into device)

#!/usr/local/bin/ruby
require 'rubygems'
require 'snmp'
include SNMP

manager = Manager.new(:Host => '10.20.9.53')
varbind = VarBind.new("1.3.6.1.2.1.69.1.1.3.0", Integer(1))
manager.set(varbind)
manager.close

Result:
warbird soaftp # ./lo.rb
[cut crap]
/usr/local/lib/ruby/gems/1.8/gems/snmp-0.5.1/lib/snmp/manager.rb:264:in
`set': host 10.20.9.53 not responding (SNMP::RequestTimeout)
        from ./lo.rb:8

This looks like lie to me :
warbird soaftp # ping 10.20.9.53
10.20.9.53 is alive
warbird soaftp #
Using snmpset from net-snmp package I'm able to set this value..

Get is OK but I'm not able to create working version of set :(

Help please :)

Can anybody help me what is the issue?

Thanks in advance

Looks like line 28 is passing a number somewhere rather than a string.

As this is a mailing list, I have no idea what "above" is.

Pay attention to the above error. It says that what you are applying
the method `encode` to is a Fixnum, a number.

All the rest of the stacktrace is probably unnecessary to post.

try:

varbind = VarBind.new("1.3.6.1.2.1.69.1.1.3.0", Integer.new(1))
