Net::POP3 and Firewall

[Mike Ho]

Hi,
I'm trying to use Net:OP3 from behind a firewall and I can't get past
this error
C:/ruby/lib/ruby/1.8/net/protocol.rb:206:in `initialize': Bad file
descriptor - connect(2) (Errno::EBADF)

I had a similar error when trying to access a url via http but I got
around it by using a Net::HTTP:roxy i.e.

host = 'whatever '
path = '/../ etc'

proxy_addr = 'my.proxy.addr'
proxy_port = myProxyPort

response = Net::HTTP:roxy(proxy_addr, proxy_port).get_response(host,
path)
puts response


I've been unable to find anything similar for Net:OP3 ie code like
this

pop = Net:OP3.new(...)

just dies and gives the error at the start of this post.

What do I need to do? Are there some ENV vars that need setting? I've
spent a day Googling etc. but go nowhere!

Thanks

Mike

This code woks on my home PC - i.e. no firewall. Does anyone know what's
needed for it to run from behind a firewall?
###############
require 'net/pop'


pop = Net:OP3.new('pop.mail.yahoo.co.uk', 110, false)
pop.start('myUserName', 'myPwd')
if pop.mails.empty?
puts 'No mail.'
else
i = 0
pop.each_mail do |m|
File.open("inbox/#{i}", 'w') do |f|

f.write m.pop
end


i += 1
end
puts "#{pop.mails.size} mails popped."
end
pop.finish

#################

I'd really appreciate any thoughts or comments.

Thanks

Mike

I don't know of any programmatic way to do this - have you spoken to your
firewall administrator? He will need to allow POP3 traffic out to the=20
Internet (at least from the box hosting your app to the POP3 server it is
trying to contact) and back again.

You could also check out SOCKS, which may enable you to proxy through
the firewall.
