ssh 无法连接，我不明白为什么

我正在尝试通过 ssh 从 mac (osx 10.14.4) 连接到 linux 机器 (Ubuntu 18.04.2)。我不是 shh 专家，这是我第一次尝试使用它，但似乎发生的情况是连接正常但在同一时刻停止了。

这是 Mac 上详细 shh 的最后几行

debug1: Authentication succeeded (publickey).
Authenticated to 192.168.1.100 ([192.168.1.100]:22).
debug1: channel 0: new [client-session]

debug1: Sending env LC_TERMINAL = iTerm2
packet_write_wait: Connection to 192.168.1.100 port 22: Broken pipe

这是 Linux 上的 ssh 服务的状态

giu 20 11:11:14 ezabba-Aspire sshd[29891]: pam_unix(sshd:session): session closed for user ezabba

所以我很无知，但我可以看到Accepted publickey和session opened for user之后立即出现session closed for user，但为什么呢？我不明白我做错了什么。

我遇到过类似的问题，并通过将此配置添加到 ssh 配置中解决了它。
