  • 2. using lambda, binding happens immediately?
    Note: parts of this message were removed by the gateway to make it a legal Usenet post. I have this code: require 'test/unit' require 'leapyear' class LeapYearTest < Test::Unit::TestCase def setup @ly = LeapYear.new end def LeapYearTest.generate_tests filename = "testdata.dat" file = File.new(filename, "r") file.each_line do |line| year, is_leap = line.split; code = lambda { assert_equal(is_leap.downcase=="true", @ly.isleap?( year.to_i)) } define_method("test_isleap_" + year, code) end file.close end end What I want to know is why when I use define_method("name") {block;} instead of define_method("name", lambda{block}) the binding seems to happen later (after the each_line loop)? Is there a reason behind that? Thanks, Sammy Larbi
  • 3. xml-mapping lib question?
    Hi all, I got a xml looking like this. <VolPoint Strike="10" OptionType="Rr Mkt" Interp="1">-0.015523356673284</VolPoint> I tried to create a ruby class for it which is used by xml-mapping library. class VolPoint include XML::Mapping text_node :Interp, "@Interp", :default_value=>nil text_node :Strike, "@Strike", :default_value=>nil text_node :OptionType, "@OptionType", :default_value=>nil text_node :VolValue, "text()", :default_value=>nil # Does not work here end But this class could not get the text from VolPoint element(last line of code). Could anyone tell me how to get the value out of the VolPoint? Cheers!

cgi/session , deleting old sessions.

Hi,

I am wondering how I would go about deleting files created by
CGI::Session, there is a huge build up of files in /tmp(everytime a new
session is initiated a new one is created) and I can't think of anyway
(beside a crontab) of deleting them, or I could use the .delete method
supplied by cgi/session but this way i need to count on the user logging
out so i can call .delete, not very efficient either.
I looked into using MemoryStore but the eruby instance doesn't last long
enough.

Any help is greatly appreciated,
rob

now i'm noticing that the create of session is not atomic... but that's for

2.Telnet - attempting to initiate a telnet session within an established telnet session

My company builds a product that has a dual slot architecture for
redundancy.  Each slot has 2 significant Ethernet interfaces; one for
network connectivity and one for connectivity between slots.  Only one
of the slots is accessible from the network at a time (the other is
meant to be a backup).  The two slots communicate via a common
Ethernet backplane and each slot has a different IP address (10.0.0.9
and 10.0.0.10).

I am trying to build a script with Ruby that allows me to first telnet
into the active slot using it's network address (easy - mission
accomplished) but then to also telnet into the backup slot over the
Ethernet backplane within the same telnet session.  I want to issue
commands in order to gather data such as uptime, disk usage, etc...

I am getting hung up on the password prompt when trying to connect to
the second slot.  I can't seem to send the password info with carriage
return so I can gain access to the second slot and issue additional
commands.

The code I have written is in the testing phase and is clearly not
perfect.

Here is my code:

require 'net/telnet'

top_node = ARGV[0]

tn = Net::Telnet::new( "Host" => top_node,
                              "Timeout" => 10,
                              "Prompt" => /[$%#>] \z/n)
 tn.login("root", "lab") { |c| print c }
 tn.cmd("date") { |c| print c }
 print ARGV[0]
 print " - "
 tn.cmd("./uptime") { |c| print c }
 test = tn.cmd("ifconfig eth0 | ifconfig eth0 | awk '/inet addr:/
{print $2 }'")

 if test.include?("addr:10.0.0.9")
    tnbackup = "10.0.0.10"
 else
    tnbackup = "10.0.0.9"
 end

 print "\n\nTelnetting to Backup HFM " + "(" + tnbackup + ")\n\n"

 tn.cmd("telnet " + tnbackup + " -l root") { |c| print c }

 tn.waitfor(/Password:\s*/im) { |c| print c }
 tn.puts("lab")
 tn.cmd("ifconfig eth0 | ifconfig eth0 | awk '/inet addr:/ {print
$2 }'") { |c| print c }
 tn.cmd("exit") { |c| print c }
 tn.close

Has anyone successfully telnet into other devices from within an
established telnet session?  Let me know if I am not clear with my
problem and if I need to clarify it more.

Any help is greatly appreciated.

Thanks,

Heath
