autosshでsshを永続化(?)

Last updated at Posted at 2014-07-19

fuseモジュールが必要のため、OpenVZでは使えません。

rpm

mac

brew install autossh
autossh -M 0 -f \
 -NL 8080:localhost:8080 remotesrv
  • -f : バックグラウンド
  • -M : モニタポート(理解していないが0指定)
  • 後はいつもの。

動作テスト

  1. PCをネットから切断。
  2. sshが絶対に切れたと思う時間だけ待って再度ネットに接続。
  3. 10秒後位にsshがつながっていることを確認。

終了方法

killall autossh

便利に使うために

autoconnect.sh
#!/bin/sh

killall -9 autossh
killall -9 ssh
AUTOSSH="autossh -M 0 -f -o Compression=yes"

# alminium
$AUTOSSH -NL 8081:localhost:8081 remotesrv
# rdp1
$AUTOSSH -NL 3391:192.168.11.11:3389 remotesrv
# rdp2
$AUTOSSH -NL 3392:192.168.11.12:3389 remotesrv
# icinga
$AUTOSSH -NL 8082:localhost:80 remotesrv2

open -a "Google Chrome.app" $HOME/autoconnect.html
autoconnect.html
<style>
* {
  line-height: 2em;
}
</style>
<ul>
  <li><a href="http://localhost:8081/projects/myproject/issues?per_page=100">8081: remotesrv alminium</a>
  <li><a href="http://localhost:8081/jenkins/">8081: remotesrv jenkins</a>
  <li><a href="http://localhost:8082/cgi-bin/icinga/status.cgi">8082: icinga remotesrv2</a>
  <li>3391: rdp1</a>
  <li>3392: rdp2</a>
  • autoconnect.sh を実行。

モバイル環境で使ってみた

autosshが勝手に再接続してくれない(?)ので手動で./autoconnect.shを実行しています。
複数のportfowardingをやってくれる点で便利。
