Linkstation ls-hgl にSquidをインストールしてプロキシサーバにしよう
タイトルの通りです。外部からアクセスできるサーバにしたい場合は、モデムやルータからls-hglへのポートを解放しておく必要があります。
※以下の作業は、すべてsshでログインしたls-hgl上で、ネイティブ開発環境で行います。
※現時点の最新版は3.2.5です。
squidのソースをダウンロードし、展開します。

プロキシサーバの設定ファイルです。
/usr/local/develop/etc/squid.conf を編集します。以下設定例です。

# Deny CONNECT to other than secure SSL ports
#http_access deny CONNECT !SSL_ports
# We strongly recommend the following be uncommented to protect innocent
# web applications running on the proxy server who think the only

# INSERT YOUR OWN RULE(S) HERE TO ALLOW ACCESS FROM YOUR CLIENTS

auth_param basic program /usr/local/develop/libexec/basic_pam_auth ←linuxのアカウントで認証する
acl password proxy_auth REQUIRED ←linuxのアカウントで認証する

# Example rule allowing access from your local networks.
# Adapt localnet in the ACL section to list your (internal) IP networks
# from where browsing should be allowed
http_access allow localnet
http_access allow localhost
# And finally deny all other access to this proxy
#http_access deny all ←全ポート中継します
# Squid normally listens to port 3128
http_port 8888 ←ポート番号
# Uncomment and adjust the following to add a disk cache directory.

ls-hglのアカウントを使用して、proxyサーバにログインするためsquidからpamライブラリを使用できるように設定します。
/etc/pam.d/squid というファイルを作成します。内容は以下の通りです。
auth required /lib/security/pam_unix.so
account required /lib/security/pam_unix.so
/etc/init.d/squid.sh というファイルを作成します。 内容は以下の通りです。
#! /bin/sh
#
# Start/stop the Squid daemons.
#
#
start_squid()
{
/usr/local/develop/sbin/squid -z
/usr/local/develop/sbin/squid
}
#
# Start the Squid server processes.
#
start()
{
echo $"Starting Squid services: "
killall "squid" > /dev/null 2>&1
start_squid
}
#
# Stop the Squid server processes.
#
stop()
{
echo 'Stop servecies: squid'
/usr/local/develop/sbin/squid -k kill
sleep 2
}
#
# Usage statement.
