我正在安装 OrangePi（比 Rasp 更强大）。在仅使用默认 root 用户安装系统后，我想添加一个新用户并从 ssh 连接
adduser foobar
我已创建所有文件/home/foobar
但我无法切换用户
# su foobar
#
当我尝试从 ssh 连接时
ssh foobar@ip
连接随即关闭。
如果我ssh -v -v -v foobar@ip
OpenSSH_6.9p1, LibreSSL 2.1.8

我创建了两个不同的用户只是为了尝试，但都失败了/etc/passwd
gil:x:1002:1006:Gil,,,:/home/gil:/bin/zsh
toto:x:1000:1004:,,,:/home/toto:/bin/bash
和
/var/log/auth.log' returns
'Dec 27 08:25:26 orangepi su[2877]: Successful su for gil by root

Dec 27 08:25:26 orangepi su[2877]: pam_unix(su:session): session closed for user gil
任何想法 ？
答案1
抱歉，我回答了，但没有评论。您显示的情况是因为用户foobar没有默认 shell 而发生的。
要检查它，请尝试以su以下方式运行：su -s /bin/bash foobar以 root 身份运行。
如果foobar@pi出现美元符号那么我的答案就是正确的。
