■debian stretchでスピードテストを行うツールを検討してみる。 $ lsb_release -d Description: Debian GNU/Linux 10 (buster) ■今回試すspeedtestは7つ。 fastパッケージは見つからず、検索結果が多くなるので除外。 NetSpeedも検索結果にはあるが、GUIなので除外。 視点を変えてみるのも面白いが、現状として、結果的にはwget/curlで十分。 Monitoring Network Bandwidth and Speed in Linux https://itsfoss.com/network-speed-monitor-linux/ $ echo -e "NetSpeed\nspeedtest-cli\nnethogs\n^nload\n^cbm\n^iperf\nvnstat\niftop" | \ awk '{a=index($1,"^")+1;print "echo \042["NR-1,substr($1,a)"]\042;apt-cache search "$1}' | sh [0 NetSpeed] cairo-dock-netspeed-plug-in - Netspeed plug-in for Cairo-dock gnome-applets - Various applets for the GNOME panel - binary files mate-applets - Various applets for the MATE panel mate-applets-common - Various applets for the MATE panel (common files) [1 speedtest-cli] speedtest-cli - Command line interface for testing internet bandwidth using speedtest.net [2 nethogs] nethogs - Net top tool grouping bandwidth per process [3 nload] nload - realtime console network usage monitor [4 cbm] cbm - display in real time the network traffic speed cbmc - bounded model checker for C and C++ programs [5 iperf] iperf - Internet Protocol bandwidth measuring tool iperf3 - Internet Protocol bandwidth measuring tool [6 vnstat] vnstat - console-based network traffic monitor vnstati - image output support for vnStat [7 iftop] iftop - displays bandwidth usage information on an network interface ■1 speedtest-cli Webサービスもあるものの、基本的にはソケットテスト。 プロキシを通過しないし、IPv6での接続を試みるなど、FW等でブロックされる私の環境には向かないツール。 SPEEDTEST https://www.speedtest.net/ $ sudo apt-get install -y speedtest-cli $ speedtest --version 2.0.2 ■計測出来なかったので、何をしているか見たときのコマンド。 $ strace speedtest-cli --simple --secure | tee -a speedtest-cli.log ■ヘッダが無いので付けてみる。 ※距離は使用する環境によって異なる。 $ speedtest --list | awk 'BEGIN{print " ID) 組織名(市町村区, 国名) [距離 km]"}/Japan/{print $0}' ID) 組織名(市町村区, 国名) [距離 km] 14623) IPA CyberLab (Bunkyo, Japan) [20.54 km] 24333) Rakuten Mobile , Inc (Tokyo, Japan) [24.93 km] 15047) OPEN Project (via 20G SINET) (Tokyo, Japan) [24.93 km] 32907) KFNET (Tokyo, Japan) [24.93 km] 33558) Gnehc LLC (Tokyo, Japan) [24.93 km] 7139) SoftEther Corporation (Tsukuba, Japan) [29.60 km] 6087) Allied Telesis Capital Corporation (Fussa-shi, Japan) [44.67 km] 8407) Allied Telesis Capital Corporation (Sagamihara, Japan) [51.65 km] 6766) JAIST(ino-lab) (Nomi, Japan) [297.74 km] 24774) Local24 Inc., (Kyoto, Japan) [377.08 km] 6405) Allied Telesis Capital Corporation (Misawa, Japan) [550.41 km] 18709) extride inc (Hitoyoshi, Japan) [926.32 km] 6581) haza (Haebaru, Japan) [1573.40 km] 21118) GLBB Japan (Naha, Japan) [1575.13 km] 30230) Lequios (Naha City, Japan) [1575.13 km] 31181) Allied Telesis Capital Corp.
