The following code
require 'net/ftp'
ftp = Net::FTP.new('www.ruby-lang.org')
ftp.login
ftp.chdir('pub/ruby/contrib')
files = ftp.list('n*')
Generates
/usr/lib/ruby/1.9/net/ftp.rb:279:in `peeraddr': getnameinfo:
System error (SocketError)
from /usr/lib/ruby/1.9/net/ftp.rb:279:in sendport' from /usr/lib/ruby/1.9/net/ftp.rb:298:inmakeport’

from /usr/lib/ruby/1.9/net/ftp.rb:628:in `list’
from t.rb:8
I’ve tried rebuilding with --with-lookup-order-hack=INET: made no
difference.
Any ideas?
Cheers

No ideas, but here is another data point. I ran the code on my Mac OS X
machine running Panther and saw slightly different results:
/tmp> ./ftp_test.rb

maybe it is not an OSX error?

I’d like to echo your woes and point to my own look into the problem:

It didn’t get any traction at the time of posting, though. Hopefully
yours will do better
