網路監控系統設計與實作

隨著企業快速的成長，原本單純的企業網路環境已日趨複雜，為求維持企業競爭優勢、強化領先地位，掌握各伺服器資訊、維持企業及客戶間之迅速互動是為目前最重要的工作。但通常企業內IT環境是由各種異質的平台組成，硬體管理不易，且各種網路協定和應用程式愈來愈多，只仰賴系統及網路管理員的人工管理是不夠的，強大的網管系統工具成為迫切需要，目前有許多商業套裝軟體都是用來管理網路監控，但無法滿足每一個企業的需求。因此，本論文使用Linux系統搭配Perl程式語言為主幹的網路管理系統，系統會在指定的時間自動更新監控網路現況並輸出HTML格式的網頁，若有出現問題的伺服器，系統會使用顯目的背景顏色及警示聲音來警告相關人員，網管人員可以透過瀏覽器監視及控制各伺服器的狀況，也可很輕易的修改程式碼，達到符合企業的需求。此系統還搭配OpenVPN、OpenLDAP等Open Source軟體，讓網管人員隨時隨地都可以使用VPN方式，連線回公司，透過LDAP伺服器認證成功後取得相關權限，即可獲取所需資源來達成網路監控管理的目的。

With rapid growth of business enterprises, the originally simple enterprise network environment has been complicated day by day. In order to maintain enterprise’s competitive advantage, it is important to constantly grasp the status of dynamically connected enterprise network’s, and to maintain the interactivities between enterprise and customer. But usually IT environment in enterprises is made up of various kinds of heterogeneous platforms, including various kinds of network protocols and application software, making manual management by system and network administrator difficult. Currently, commercially available software can be used for managing the enterprise network at present, but they are unable to meet every enterprise's requirement. Therefore, we designed an network monitoring and control system using PERL procedure language on the Linux open source system platform to monitor and control enterprise network and output network status in HTML format with automatic renewal at designated time internals. if there is server failure in the enterprise’s network, the system will change the background color on the monitoring webpage and sound alarm to warn relevant personnel, The network management personnel can also control the network easily according to the demand the monitored of enterprise network. This system also use Open Source software , such as OpenVPN, OpenLDAP, etc., to construct the system that enable network management personnel to establish a VPN channel back to enterprise whenever and wherever needed via internet after being successfully authenticated through LDAP, and obtained necessary resources .
