點對點網路測速軟體 iPerf3
文章目錄
需求
需要一個測試點對點網路速度的軟體, 要有以下幾項功能
- 免費
- 支援 Windows 和 Linux
- 只測網路, 不測 I/O
- 有簡易報表
找了一下, iPerf3 算是符合需求
安裝方法 (Server 和 Client 是同一個程式)
- 連線到 https://iperf.fr/iperf-download.php, 選擇需要的作業系統
- 如果是 Windows, 直接下載 iperf-3..-win64.zip 即可, 免安裝, server/client 是同一個執行檔
- 以 Ubuntu 為例, 理論上是執行這個指令就可以了
1sudo apt-get install iperf3 - 若是無法安裝, 可能是缺了某些 library, 可參考官網指示, 如下 (這是我執行時候的範本, 請參考官網看最新的指令)
1sudo apt remove iperf3 libiperf0 2sudo apt install libsctp1 3wget https://iperf.fr/download/ubuntu/libiperf0_3.9-1_amd64.deb 4wget https://iperf.fr/download/ubuntu/iperf3_3.9-1_amd64.deb 5sudo dpkg -i libiperf0_3.9-1_amd64.deb iperf3_3.9-1_amd64.deb 6rm libiperf0_3.9-1_amd64.deb iperf3_3.9-1_amd64.deb
測試 (Server 端)
- 不論 Windows 或是 Ubuntu, 指令都是一樣的簡單, 加上 -s 就可以了. 有需要的話, 可以加上 -p 指定 port
1$ iperf3 -s -p 5201 2----------------------------------------------------------- 3Server listening on 5201 4-----------------------------------------------------------
測試 (Client 端)
- 執行時指定 server 的 IP, port, 還有測試的時間長度就好, 他會顯示每秒的測速結果還有最後的平均值

後記
- iPerf3 預設是測試 upload 的速度, 若要測試 download, 請記得加上 -R 參數
- 有個不錯的地方是, 他的 server 端也會有 log, 如下, 這樣很方便.
