尝试通过 ssh 执行命令，但我没有收到任何回复。服务器 A 是 Solaris 计算机，服务器 B 是带有 OpenBSD sshd 的 SUSE linux。已检查
和其他来源，但无法解决。
我正在尝试的命令是（在 bash 中）：
ssh -v -i .ssh/id_rsa -p1234 user2@abcdefg 'ls -al'
（尝试不带引号和双引号）
编辑：我在 sshd 端启用了 Loglevl 并从 auth 文件中获取了以下内容

答案1
我不确定这是否与您的情况相关，但我能够通过编辑解决 Ubuntu 16.10 上的类似问题.bashrc：
从：
# If not running interactively, don't do anything
case $- in
*i*) ;;
*) exit;;
esac
到：
# If not running interactively, don't do anything
case $- in
*i*) ;;
*) return;;
esac
exit因此，如果您可以在配置文件中的任何位置找到，也许这就是正在执行的操作讨厌的。
只需将其替换为return.
干杯，
