写入:对端重置连接

当我打开我的电脑(Ubuntu 19.04)并尝试第一次登录我的ssh服务器(Raspbian buster)时,我得到write: connection reset by peer

trp@trp-pc:~$ ssh -vvv [email protected]
OpenSSH_7.9p1 Ubuntu-10, OpenSSL 1.1.1b  26 Feb 2019

write: Connection reset by peer

但如果我ping尝试ssh两次,我就能连接上,一切都很顺利(没有断开连接等),而且我可以与服务器进行多次 ssh 会话。如果我重新启动 PC,问题会再次出现(第一次登录尝试)。

更新#1: 我检查了日志(auth.log),但即使LogLevel DEBUG3登录尝试失败也不存在。

更新#2: 我尝试指定 Mac、Kex 和 Key,但没有任何变化()ssh -o KexAlgorithms=diffie-hellman-group16-sha512 -o [email protected] -o HostbasedKeyTypes=ssh-rsa -c aes192-ctr

答案1

问题出在我的路由器/调制解调器上。我将地址池改回默认值(从 .2 改为 .254),删除了服务器的静态 IP(已在路由器/调制解调器设置中设置),连接到服务器并设置静态 IP。现在一切都运行顺利。
