 * 讓 Pootle 中文翻譯網站可以同時支援 80 跟 8080 port
   * [源起] 由於 pootle 是使用 Python 撰寫的 PO 翻譯網頁介面,雖然可以直接用 --port=80 的方式強制執行, 但如果加在 /etc/default/pootle 的 POOTLE_OPTIONS 中, 卻會遇到權限的問題.
   * [參考] 
   * 安裝 libapache2-mod-proxy-html
{{{
# apt-get install libapache2-mod-proxy-html
}}}
   * 鏈結 proxy.conf , proxy.load, proxy_http.load
{{{
# cd /etc/apache2/mods-enabled/
/etc/apache2/mods-enabled# ln -s ../mods-available/proxy.conf
/etc/apache2/mods-enabled# ln -s ../mods-available/proxy.load
/etc/apache2/mods-enabled# ln -s ../mods-available/proxy_http.load
}}}
   * 修改 /etc/apache2/mods-enabled/proxy.conf

 * ssh port forwarding
   * [源起] 許多機器往往因為網路環境的緣故(Ex: 在防火牆背後 或 浮動位址)而無法直接存取 SSH port. 此時可以採用
{{{
GatewayPorts
    Specifies whether remote hosts are allowed to connect to ports
             forwarded for the client.  By default, sshd binds remote port
             forwardings to the loopback address.  This prevents other remote
             hosts from connecting to forwarded ports.  GatewayPorts can be
             used to specify that sshd should allow remote port forwardings to
             bind to non-loopback addresses, thus allowing other hosts to con‐
             nect.  The argument may be “no” to force remote port forwardings
             to be available to the local host only, “yes” to force remote
             port forwardings to bind to the wildcard address, or
             “clientspecified” to allow the client to select the address to
             which the forwarding is bound.  The default is “no”.
