<p>條件是</p>
<ul>
<li>Linux</li>
<li>UTM</li>
<li>VMware ready</li>
<li>SMP multi processor support</li>
<li>IPSec (Site to  Site VPN返公司)</li>
<li>PPTP</li>
</ul>
<p>Wiki 了一會，再用了Google找找。最後選擇了Astaro。<br />
<a href="http://www.astaro.com/landingpages/en-worldwide-homeuse">http://www.astaro.com/landingpages/en-worldwide-homeuse</a></p>
<h3>安裝</h3>
<p>安裝之前，先在Astaro網頁request了一套home license （後來發現無license也能下載，並且有30日試用）</p>
<p>下載完一個556MB ISO後就準備安裝</p>
<p>在ESXi內，先開一個VM，<br />
CPU : Single socket 2 Core<br />
RAM : 2GB ﹣4GB  (今次開了3GB試試)<br />
HDD : 10GB (無10GB 不肯安裝)<br />
Network : 3xE1000 (LAN,WAN1,WAN2)</p>
<p>再Mount起ISO直接INSTALL。安裝完REBOOT一次就問LAN IP ADDRESS 就完成了。</p>
<p>第一次入WEB界面會有Wizard幫助，問了十個問題左右就完成。</p>
<p>Main Screen 選項分類不太難用，Dashboard 比pfSense 詳細。</p>
<p><img class="alignnone size-medium wp-image-1049" title="Astaro Main Screen" src="http://www.stephenyeong.idv.hk/wp/wp-content/uploads/2012/02/Astaro-Main-Screen-300x228.png" alt="" width="300" height="228" /></p>
<h3>Free Home License</h3>
<p>進入Management -&gt; Licensing 就能上載伸請來的Free Home License。<br />
Free Home 只是沒有HA 以及限際 50個LAN IP使用，IPS、Antivirus、Anti-spam 提供三年免費更新。</p>
<p><a href="http://www.stephenyeong.idv.hk/wp/wp-content/uploads/2012/02/Astaro-Home-License.png" rel="lightbox[1047]" title="Astaro Home License"><img class="alignnone  wp-image-1050" title="Astaro Home License" src="http://www.stephenyeong.idv.hk/wp/wp-content/uploads/2012/02/Astaro-Home-License.png" alt="" width="464" height="458" /></a></p>
<p><a href="http://www.stephenyeong.idv.hk/wp/wp-content/uploads/2012/02/Astaro-License-Usage.png" rel="lightbox[1047]" title="Astaro License Usage"><img class="alignnone  wp-image-1051" title="Astaro License Usage" src="http://www.stephenyeong.idv.hk/wp/wp-content/uploads/2012/02/Astaro-License-Usage.png" alt="" width="464" height="343" /></a></p>
<h3>IPSec (Site to Site VPN)</h3>
<p>設定上遇到了問題，原來Astaro是不支援Agressive mode IKE，只有Main Mode IKE 可用。沒了Agressive Mode 只好修改公司ROUTER 個設定，用dyndns host name 為peer identity。</p>
<h3>PPTP</h3>
<p>設定比較簡單，因為預設了IP Address range。只需設定USER就完成。用IPAD測試過可以用。</p>
<h3>Speed test &#8211; Speedtest.net</h3>
<p>由於Astaro有IPS及WEB PROXY，SPEEDTEST.NET只能到200Mbps左右。</p>
<p><img class="alignnone" src="http://www.speedtest.net/result/1767969119.png" alt="" width="300" height="135" /></p>
<h3>Speed test &#8211; iperf</h3>
<p>但用iperf 返公司電腦 WAN／VPN (BB100)分別有90Mbps及60Mbps</p>
<p>CPU使用方面，<br />
90Mbps NAT時使用了15%<br />
60Mbps IPSec Tunnel 時使用了25%</p>
<p>NAT test, JPerf to Office WAN<br />
<a href="http://www.stephenyeong.idv.hk/wp/wp-content/uploads/2012/02/iperf-to-HKBN-100Mbps.png" rel="lightbox[1047]" title="iperf to HKBN 100Mbps"><img class="alignnone size-full wp-image-1052" title="iperf to HKBN 100Mbps" src="http://www.stephenyeong.idv.hk/wp/wp-content/uploads/2012/02/iperf-to-HKBN-100Mbps.png" alt="" width="531" height="491" /></a><a href="http://www.stephenyeong.idv.hk/wp/wp-content/uploads/2012/02/iperf-to-HKBN-100Mbps-CPU-loading.png" rel="lightbox[1047]" title="iperf to HKBN 100Mbps CPU loading"><img class="alignnone size-full wp-image-1055" title="iperf to HKBN 100Mbps CPU loading" src="http://www.stephenyeong.idv.hk/wp/wp-content/uploads/2012/02/iperf-to-HKBN-100Mbps-CPU-loading.png" alt="" width="731" height="353" /></a></p>
<p>VPN test, Jperf to Office LAN through 3DES-SHA1 Tunnel<a href="http://www.stephenyeong.idv.hk/wp/wp-content/uploads/2012/02/iperf-to-VPN.png" rel="lightbox[1047]" title="iperf to VPN"><img class="alignnone  wp-image-1053" title="iperf to VPN" src="http://www.stephenyeong.idv.hk/wp/wp-content/uploads/2012/02/iperf-to-VPN.png" alt="" width="740" height="500" /><br />
</a><a href="http://www.stephenyeong.idv.hk/wp/wp-content/uploads/2012/02/iperf-to-VPN-cpu-loading.png" rel="lightbox[1047]" title="iperf to VPN cpu loading"><img class="alignnone size-full wp-image-1056" title="iperf to VPN cpu loading" src="http://www.stephenyeong.idv.hk/wp/wp-content/uploads/2012/02/iperf-to-VPN-cpu-loading.png" alt="" width="695" height="337" /></a></p>
<h3>Speed test &#8211; FTP</h3>
<p>再測試用filezilla由ftp.cuhk.edu.hk下載檔2個檔案</p>
<p>Fedora-16-x86_64-Live-Desktop.iso (633339904 bytes)<br />
Fedora-16-x86_64-Live-KDE.iso (729808896 bytes)</p>
<p><img class="alignnone size-full wp-image-1069" title="Screen Shot 2012-02-12 at 5.26.23 PM" src="http://www.stephenyeong.idv.hk/wp/wp-content/uploads/2012/02/Screen-Shot-2012-02-12-at-5.26.23-PM1.png" alt="" width="710" height="135" /><br />
最後共用了45秒完成。即是1.3GB/45 = 28.8MB/s (~230Mbps)<br />
<a href="http://www.stephenyeong.idv.hk/wp/wp-content/uploads/2012/02/Screen-Shot-2012-02-12-at-5.26.52-PM1.png" rel="lightbox[1047]" title="Screen Shot 2012-02-12 at 5.26.52 PM"><img class="alignnone size-full wp-image-1070" title="Screen Shot 2012-02-12 at 5.26.52 PM" src="http://www.stephenyeong.idv.hk/wp/wp-content/uploads/2012/02/Screen-Shot-2012-02-12-at-5.26.52-PM1.png" alt="" width="469" height="59" /></a></p>
<h3>Speed test &#8211; BitTorrent</h3>
<p>試用BitTorrent下載幾個大檔案</p>
<p>ubuntu-11.10-server-i386.iso + ubuntu-11.10-server-amd64.iso + ubuntu-11.10-desktop-i386.iso + ubuntu-11.10-desktop-amd64.iso</p>
<p>同時下載4個六百幾MB檔案，尖峰可達12MB/s</p>
<p><a href="http://www.stephenyeong.idv.hk/wp/wp-content/uploads/2012/02/BT-test.png" rel="lightbox[1047]" title="BT test"><img class="alignnone size-medium wp-image-1080" title="BT test" src="http://www.stephenyeong.idv.hk/wp/wp-content/uploads/2012/02/BT-test-300x88.png" alt="" width="300" height="88" /></a></p>
<p>預告，下一回寫Performance Tuning.</p>

<li>MAC OSX reinstall / upgrade 比Windows 好</li>
<li>要製作MAC OSX的開機/安裝碟最好用返MAC OS</li>

<p>啟動Virtual Machine 後，如網絡環境的IP不是192.168.1.1/24，可以在Console 輸入以下command修改IP</p>

<p>作為AP，LAN的DHCP應該停用。<br />
Network-&gt;Interface-&gt;LAN-&gt;DHCP Server, Disable DHCP for this interface</p>
<p><strong>Packages</strong><br />
可以REMOVE iptables 因為bridge 沒用</p>
<p>Install packages</p>
<ul>
<li>wpad-mini (WPA-PSK 必需)</li>
<li>kmod-ath9k (Wireless LAN driver，視乎用什麼卡)</li>
</ul>
<p>reboot  一次再設定Wireless Lan card</p>
<p><strong>Wireless Lan</strong></p>
<p>最基本只需要設定ESSID及Wireless Security。並且將Network 加入到 lan (bridge with LAN)</p>
<p><img class="alignnone  wp-image-977" title="Interface Config ESSID bridge LAN" src="http://www.stephenyeong.idv.hk/wp/wp-content/uploads/2012/01/Interface-Config-ESSID-bridge-LAN.png" alt="" width="589" height="187" /></p>

<p><strong>vSwitch Security</strong></p>
<p>最後一步，就是設定vmware 的vSwitch Security頁內的Promiscuous Mode 一定要設定為Accept，否則wireless client不能Bridge 到LAN zone，全部OpenWrt MAC以外的packet會被 drop.</p>

<p>1. 先從價格入手，到www.price.com.hk 找 $5000 以下的相機。由於想質素比較好，所以只在 “DSLR 數碼單鏡反光相機” 內找。<br />
原來這個價位最熱門的頭五位，全部是可換鏡無反相機 （無反當單反？？）。</p>
<p>2. 走去對比Review，Google 到一個很好的網站可以提供更多深入比對。<br />

<p>這個Website 有好多平時覺得重要但沒有在產品規格上清楚列名的資訊。</p>
<p>例如Shutter lag, battery life, image quality</p>
<p>而這個Website Image quality 分數以 <a title="While other websites publish information about JPEG image quality, only DxO Labs provides the first publicly-accessible database of objective and in-depth RAW sensor image quality measurements." href="http://www.dxomark.com/" rel="nofollow">DXOMark</a> 為基楚。</p>
<p><a title="While other websites publish information about JPEG image quality, only DxO Labs provides the first publicly-accessible database of objective and in-depth RAW sensor image quality measurements." href="http://www.dxomark.com/" rel="nofollow">DXOMark</a> - <a href="http://www.dxomark.com/index.php/About/In-depth-measurements/Measurements">http://www.dxomark.com/index.php/About/In-depth-measurements/Measurements</a></p>
<p>DXOMark 基於3個因素</p>
<ol>
<li>Portrait Score (color depth)</li>
<li>Landscape Score (dynamic range)</li>
<li>Sports Score (low-light ISO)</li>
</ol>
<blockquote><p>The Sensor Overall Score is an average of the <a href="http://www.dxomark.com/index.php/About/Sensor-scores/Use-Case-Scores#Portrait" target="_self">Portrait Score</a> based on color depth, the <a href="http://www.dxomark.com/index.php/About/Sensor-scores/Use-Case-Scores#Landscape" target="_self">Landscape Score</a> based on dynamic range, and the <a href="http://www.dxomark.com/index.php/About/Sensor-scores/Use-Case-Scores#Sports" target="_self">Sports Score</a> based on low-light ISO</p></blockquote>
<p>其中 Sports Score 是最高可用ISO值。定議最高能提供 30dB SNR的ISO。30dB SNR 足夠提供 9 EV Steps 及 18bit 的色深。</p>
<blockquote><p>Thus low-light ISO is the highest ISO setting for a camera that allows it to achieve an SNR of 30dB while keeping a good dynamic range of 9 EVs and a color depth of 18bits.</p></blockquote>
<p>以下是將 price.com.hk 找到$5000 以下最熱門 DSLR 中的頭3位在DxOMark.com中對比的結果。<a href="http://www.dxomark.com/index.php/Cameras/Compare-Camera-Sensors/Compare-cameras-side-by-side/(appareil1)/724|0/(brand)/Olympus/(appareil2)/763|0/(brand2)/Panasonic/(appareil3)/715|0/(brand3)/Sony">LINK</a></p>

<p>很明顯是APS-C片幅的SONY NEX-C3 在所有測試中表現最出衆，最後當然選擇了 SONY NEX-C3.</p>
