SSHサーバーはCentos 7を実行しており、Puttyを介してWindows 10で接続します。
いくつかのVPN設定を見つける必要があるため、複数のSSHトンネル（約2000のアドレス：ポートの組み合わせ）を設定する必要がありました。実際に動作するには、ulimit -n 8192私のプロファイルにコマンドを追加する必要がありました（スクリプトを介して）。/etc/profile.d/
実は私持つ考えられる解決策は、sshdサーバーを手動で起動することです/usr/sbin/sshd（実際にデバッグ用に実行しました-ddd）。問題は、毎回このようなことをしたくないということです。
/usr/sbin/sshd私がやっていることを複製するためににnofiles昇格し、.inを追加してアクティブにして編集してみました。明らかに、このような試みをするたびにサービスを再起動しますが、これまでは運がありませんでした。/etc/security/limits.conf8192UsePAM yes/etc/ssh/sshd_config/etc/pam.d/sshdsession required pam_limits.sosshd
