PPTPの速度測定(2)

前回の環境で、一日つなぎっぱなしにしておきましたが、問題なくつながっています。

リモートデスクトップ接続を利用してブログを書いています。この記事も、「FreeBSDでRAID1(7)」の記事もPPTP経由のリモートディスクトップで接続し記事を書きました。スクリーンショットの転送や写真の縮小などの操作も含みます。

この原稿のスクリーンショットは、手元のPCで撮り、NetBSDのサーバーに保存したものです。保存するときに待ち時間を感じますが、直接つないでいたときと操作が変わらないので便利です。

■ヤマハRT57iのPPTPに関する情報
RT57iでのPPTP接続の情報です。RT58iでも同様です。

○複数ユーザの接続設定
この設定では、同時に二名まで接続できます。ユーザ登録は沢山できます。
同時接続ユーザ数は、bindするトンネル数で決まります。

[RT57i]> show config pp anonymous
pp bind tunnel3-tunnel4
pp auth request chap-pap
pp auth username Nanigashi *
pp auth username Jyugemu *
pp auth username Mumeinohito *
pp auth username Dareyara *
pp auth username Itsumonohito *
pp auth username TaniyamaRyoji *
ppp ipcp ipaddress on
ppp ipcp msext on
ppp ccp type mppe-any
ip pp remote address pool dhcp
ip pp mtu 1280
pptp service type server
pp enable anonymous
[RT57i]>

○PPTPトンネルの定義
同時二名なので、トンネルは二つ定義しています。

tunnel select 3
tunnel encapsulation pptp
pptp tunnel disconnect time 1800
tunnel enable 3
tunnel select 4
tunnel encapsulation pptp
pptp tunnel disconnect time 1800
tunnel enable 4

○接続ユーザの確認
接続しているユーザごとの情報です。
