我正在使用who命令登录用户进入我的系统我发现的是非常令人惊讶的用户名为unknown
命令结果：
myuser pts/1 Aug 6 20:27 (localhost) (unknown) :0 Aug 5 16:25 (:0) myuser pts/0 Aug 6 00:48 (localhost.localdomain)
但是,当我尝试运行w时,结果会有所不同：
20:46:53 up 1 day,23:11,3 users,load average: 1.00,1.01,1.05 USER TTY FROM LOGIN@ IDLE JCPU PCPU WHAT myuser pts/1 localhost 20:27 5.00s 0.20s 0.03s w myuser pts/0 localhost.locald 00:48 19:57m 0.08s 1.71s python2 -m guake.main
我无法在我的机器上找到任何名为unknown的用户.在尝试sudo su unknown /“(unknown)”
我试过运行最后它显示未知用户仍然登录

知道怎么样？
不久前我在Fedora主机上遇到过类似的问题.
在我的例子中,我发现是X系统在/ var / run / utmp中创建了一个错误的条目.
这里是link到页面.
也许您没有使用Fedora,但我建议尝试禁用X并检查您是否仍有(未知)用户登录.
希望这可以帮助.
