linux ruby ssh

VMware上のCentOSでsshに自分のアカウントでログインした場合

[takeshi@localhost ~]$ ssh takeshi@localhost

Net::SSHの場合

[takeshi@localhost ~]$ irb
irb(main):001:0> require 'rubygems'
require 'net/ssh'
Net::SSH.start('localhost', 'takeshi', :password => 'password') do |session|
  puts session.exec('env | sort')

これ同じマシンで動かした結果だぜ。

あー、本当によく分からん。/etc/ssh/sshd_configとか/etc/ssh/ssh_configとかも調べたけど、ローカルから環境変数を設定したい訳じゃないから、AcceptEnvとか特別なことをやるべきじゃないと思うんだけど、何か必要なのかなー。
