Recently, I love studying Slitaz and make it as powerful as normal linux distro. This mini-howto shows the simple steps on using Slitaz to build a proxy server. It just offers very basic function, please go to the official site http://www.squid-cache.org for more details. Install Sliatz, please kindly RTFM Install squid tazpkg get-install squid tazpkg [...] 近日對 Slitaz 既興趣越來越高, 但係原來佢都係有唔完美缺點既. 佢既優點當然係容量小, 電腦硬件要求低. 正正因為容量小, 軟件包支援亦相對少, 而且就算有支援亦並非代表可以有功能上既擴展. 例如, 沒有 mod_security 軟件包提供, 要各位努力 compile. 雖然 modsecurity 有完善既說明文件, 但在 Slitaz 身上卻變成有點困難. 下文會先列出必須既軟件, 最後才將安裝步驟簡單列出. 在 Slitaz, 先安裝套件: slitaz-toolchain, gcc, apache-dev, apr-dev, lua-dev, curl-dev, apr-util-dev, pcre-dev, libxml2-dev, expat-dev 用 modsecurity 網站所提及既步驟便可: 1. 先解壓 source; 2. cd ./apache2; 3. 執行 ./configure; 4. 執行 make; 5. 執行 make test; [...] 近日因為自己部 server 又唔生性咁 down 咗, 唯有又由頭安裝過. 不過始終都想找到一個較簡單既方案, 所以從網上找一些輕量既 linux distro. 雖然一般既 linux distro 功能好強, 但輕量的 linux distro 對硬件要求較低, 所以對要求低既用戶 (我 ) 仍有發展空間. Slitaz 係其中一個輕量既 linux distro 而又提供 server application. 不過發現佢個 cooking version 因為 ssl cert 有問題, 所以啟動 apache 時會有 error. 要解決依個問題就要自己動手做一張 ssl cert. 過程如下: 1. Go to /etc/ssl/misc 2. Type ./CA.sh -newca 3. Fill-in proper [...] 今日試用 Ulteo 感覺幾滿意, 但要解決遇到既問題就比較難, 不過只要肯上網搵就無乜問題. 當安裝完整個系統後, 係 ubuntu 8.04 平台在 apt-get update 後會出現 hal error Errors were encountered while processing: hal 只要執行下列指令再重新啟動電腦就可以解決問題: sudo chroot /opt/ulteo chown root:polkituser /usr/lib/policykit/* chmod 2755 /usr/lib/policykit/polkit-*-helper chmod 4754 /usr/lib/policykit/polkit-grant-helper-pam exit 參考網址: http://www.ulteo.com/main/forums/viewtopic.php?t=1343 [...] 近日見到一個由 Ulteo 提供既免費 virtual desktop 既 solution, 所以就試裝一下. 不過當中遇到了一點小問題, 當進行 apt-get update 時, 出現 error message: W: GPG error: http://archive.ulteo.com ovd-polaris Release: The following signatures couldn’t be verified because the public key is not available: NO_PUBKEY 924B005D78BFFB01 W: You may want to run apt-get update to correct these problems 找尋後發現原來缺少了 Ulteo 既 PUBKEY, 解決方法原來去簡單, 只要下載以下連結並安裝便可解決問題. [...] At Backblaze, we provide unlimited storage to our customers for only $5 per month, so we had to figure out how to store hundreds of petabytes of customer data in a reliable, scalable way—and keep our costs low. After looking at several overpriced commercial solutions, we decided to build our own custom Backblaze [...] Imagine storage that didn’t cost much more than bare drives. High density storage with RAID 6 – double-fault – protection, reasonable bandwidth and web-friendly HTTPS access. And really, really cheap. Not your enterprise’s RAID array Raw disk cost is only 5-10% of an enterprise RAID system’s cost. The rest goes for corporate jets, sales commissions, [...] 近日發現 snort 出現了一句 warning message: (http_inspect) IIS UNICODE CODEPOINT ENCODING. 找了很久才找到了簡單既解決方法. 這句錯誤其實是因為 snort 在設定網站語系 (language encoding) 時出錯. 要解決這個問題最好不要直接將該 module 停止, 因為這樣有機會出現安全漏洞, 所以只建議直接收改設定去改善這個問題. 到 snort 設定檔 /etc/snort/snort.conf 找尋 iis_unicode_map 原句為: preprocessor http_inspect: global iis_unicode_map unicode.map 1252, 將最後的數字更改為適當語系便可. 以 UTF-8 為例, 全句應為preprocessor http_inspect: global iis_unicode_map unicode.map 65001 * unicode map 可在同一個設定目錄裡尋找, 檔名為 unicode.map 參考網址: http://it.toolbox.com/blogs/locutus/snort-out-your-unicode-encoding-log-entries-21981 有需要可直接參考 snort manual: [...] 最近幫朋友用 win2008 起了個伺服器, 但部份 ASP 網頁未能成功通過 SMTP server 傳遞信息. 翻查錯誤信息, 原來係因為 unable to relay. 只要在 SMTP server 增加相應既 relay host IP 便可解決問題. 進入管理工具 –> IIS 6 –> SMTP 右按鼠鍵進入內容 在存取頁, 按下 Relay button 在相應畫面加入所需既 IP address 如果開啟 SMTP loggin, 設定成功後便可在 logging 那邊查看到 smtpsvc 服務成功運行. 如有需要可留言討論. 官方做法: 安裝 update-manager-core 修改 /etc/update-manager/release-upgrades, 將 Prompt=lts 轉為 Prompt=normal 執行 do-release-upgrade 經過一輪下載後, 升級程式便會啟動. 只要按照指示便可進行升級. [...] 以下方法雖然係引用其他師兄既, 但係小弟就過真係有效, 所以同大家分享一下. By: Daniel Petri Warning! This document contains instructions for editing the registry.
