エラー sh_dispatch_run_fatal: Connection to ***.**.***.*** port **: message authentication code incorrect lost connection

Posted at

リモートサーバーからscpでファイルをダウンロードしていたらタイトルのエラーが発生しました。

解決策

scpのときに-lオプションで帯域制限 (通信につかう通信量を制限) しました。

scp -l 5000 *** ***

原因

Linuxはネットワーク越しにファイル転送を行うとベストエフォートで動いて回線に負荷をかけるらしいので,帯域制限をしました。

環境:
Ubuntu 20.04LTS (WSL)
OpenSSH_8.2p1 Ubuntu-4
OpenSSL 1.1.1f 31 Mar 2020
