httpプロキシ下で外部サーバーにsshする[Ubuntu18.04から]

Last updated at Posted at 2020-01-10

はじめに

httpプロキシ配下にある環境から外部のサーバーにssh接続したい場面で苦労したので,備忘録の意味も兼ねて記録しておきます.
基本的にはこちらを参考としました.

手順

インストール

// sudo apt-get updateも忘れずに
sudo apt-get install squid3
sudo apt-get install connect-proxy
sudo apt-get install openssh-client

squidの設定

/etc/squid3/squid.confに以下を追記(自分の環境ではsquidでした(3がつかない)).

acl SSL_ports port 22
acl Safe_ports port 22          # ssh

ここでsquidを再起動.

// ここも自分の環境では3がつきませんでした.ここまで起動してなければstart
service squid3 restart

sshの設定

~/.ssh/configを以下のように編集.example.comの部分を対応させて下さい.

Host example.com
        Hostname example.com
        ProxyCommand connect-proxy -H <httpプロキシのurl>:<httpプロキシのport> %h %p

実行

いつも通りにssh.

ssh user@example.com

以上
