problem while connecting to memcache servers over network

[hemant]

hi,

I am using ruby memcache client,
http://seattlerb.rubyforge.org/memcache-client/ for connecting to
memcache servers.

I am attempting to connect to a memcache server located in another
machine, through internet( so no its not also in same domain and all).
Although I can open telnet prompt from the same machine at port 11211,
but memcache throws error when attempting to make a connection to the
same machine at same port:

/usr/local/lib/ruby/gems/1.8/gems/memcache-client-1.3.0/lib/memcache.rb:539:in
`request_setup': No connection to server (MemCache::MemCacheError)
       from 
/usr/local/lib/ruby/gems/1.8/gems/memcache-client-1.3.0/lib/memcache.rb:199:in
`[]'
       from a.rb:23


My code is:

require "rubygems"
require "memcache"

memcache_options = {
 :c_threshold => 10_000,
 :compression => true,
 :debug => false,
 :namespace => 'bekar_data',
 :readonly => false,
 :urlencode => false
}

CACHE = MemCache.new(memcache_options)
CACHE.servers = "xxx.xxx.xxx.xx:11211"


if ARGV.include?("-d")
 puts "Here"
 CACHE["22120192091291ahae-1"] = "3232"
 puts CACHE["22120192091291ahae-1"]
else
 puts CACHE["22120192091291ahae-1"]
end
