ssh_dispatch_run_fatal：消息驗證碼不正確
幾天以來，我在 ssh 中連接到我的伺服器時遇到了一個問題，用於代理/隧道使用。
我 - 設置
客戶
這是機器：
iMac:~ 盧卡$ sw_vers
產品名稱：Mac OS X
產品版本：10.11.6
建構版本：15G1108
iMac:~ Luca$ sudo sysctl net.inet.ip.forwarding
net.inet.ip.forwarding: 0
iMac:~ Luca$ sudo sysctl net.inet.ip.fw.enable
net.inet.ip.fw.enable: 1
在三個不同的網路上嘗試過。
瀏覽器
我正在使用 Firefox 50.0.1 瀏覽網際網路，FoxyProxy 擴展配置如下：
主機地址：127.0.0.1
埠：9999
襪子 v5
SSH 命令
我正在使用 Terminal.app 通過 ssh 連接到我的伺服器。
iMac:~ Luca$ ssh -p 53 -D 9999 luca@myIP
伺服器
luca@myServer:~$ ssh -V
OpenSSH_6.7p1 Debian-5+deb8u3，OpenSSL 1.0.1t 2016 年 5 月 3 日
luca@myServer:~$ cat /proc/sys/net/ipv4/ip_forward
1
II - 預期
連接打開後，我可以毫無問題地瀏覽任何網站（我的 IP 是我的伺服器）。
這很好，直到幾天。如果我嘗試，這仍然很好：
- 同一台伺服器 (A)，另一台電腦 (Y)
- 同一台電腦 (X)，另一台伺服器 (B)
從它的外觀來看，它不適用於我的電腦 (X) 和我的伺服器 (A)。
III - 會發生什麼
luca@myServer:~$ ssh_dispatch_run_fatal: 連接到 myIP: 消息驗證碼不正確
然後關閉連接。
此消息隨機出現。但我可以通過代理載入大數據輕鬆重現它：載入多個影片、下載大文件等……
IV - 另一種方式，類似的問題
如果我通過 sftp://（使用 FileZilla）使用相同的登錄名（luca）和相同的埠（53）連接到我的伺服器。然後我嘗試下載一個文件，每 <30 秒我收到以下錯誤：
錯誤：在數據包上收到不正確的 MAC
再一次，這只發生在我的電腦 (X) 和我的伺服器 (A) 上。如果我在同一台電腦 (X) 上嘗試另一台伺服器 (B)：沒問題。如果我在另一台電腦 (Y) 上嘗試相同的伺服器 (A)：沒問題。
V - 我嘗試過的（但沒有解決）
- 重新啟動伺服器和電腦
- 在伺服器和電腦上重新啟動 ssh/sshd
- 刪除電腦上的knowns_hosts文件
- 使用 ssh 命令指定 a
-m和-c-o GSSAPIKeyExchange=no在 ssh 命令中指定 a/etc/ssh/ssh_config取消註釋伺服器或/和電腦上的密碼和/或 MAC 行- 嘗試
-vvvvv使用 ssh 命令查看選項並讀取伺服器/電腦上的日誌，看起來沒有任何關係。任何幫助，將不勝感激。

我已經從 Mac OS El Capitan (10.11) 更新到 Mac OS Sierra (10.12)。
問題不再發生。
我仍然不知道真正的問題是什麼。
通過在 Mac 上乙太網適配器的高級設置（在 Big Sur 下）禁用 AVB/EAV 模式，我解決了這個問題。
