随分昔からインターリンクの MyIP サービスにはお世話になっていますが、2013/11/12 から突如接続できなくなりました。
FreeBSD 5.3 mpd3.18 で今までつなげていました。
ログが出力されなくなっていたので、mpd をフォアグラウンドで実行させて様子を見てみました。
ログは最後に載せますが、どうやらインターリンク側が「AUTHPROTO CHAP MSOFTv2 は断る」と言ってきて、「でも AUTHPROTO CHAP MSOFTv2 でお願い♡」「だが断る」で10回押し問答してブチ切れているらしい。
２週間ほど何もできずにいたんですが、試しにこんな設定を追加してみたら解決してしまいました。
/usr/local/etc/mpd/mpd.conf
set link disable CHAP MSOFTv2
やっと繋がって自宅メールサーバが復活した…
セカンダリメールサーバを VPS とかで作っておいたほうが良さそうです。
以下繋がらなかった時のログです。
