I am running slitaz distro, and would like to completely remove the root password. I have tried giving a blank password to the passwd command, however that did not seem to do the trick. It gave me an error password was too short, ans it still asked me for a password when I ssh-ed in. The password was just hiting the "Enter" key.
我正在运行slitaz发行版，希望完全删除根密码。我尝试过给passwd命令一个空白密码，但是这似乎并没有起到什么作用。它给了我一个错误密码太短，而且当我闪人的时候它还问我要密码。密码就是输入“Enter”键。
UPDATE:
Perhaps it has to do with the fact that slitaz uses dropbear for ssh? Because even with a blank password for root in /etc/shadow, it still prompts for a password.
更新:可能与slitaz使用dropbear作为ssh的事实有关吧?因为即使在/etc/shadow中为root设置了空白密码，它仍然会提示输入密码。

Did you try passwd -d root? Most likely, this will do what you want.
你试过wd -d根吗?很有可能，这将实现您想要的。
You can also manually edit /etc/shadow: (Create a backup copy. Be sure that you can log even if you mess up, for example from a rescue system.) Search for "root". Typically, the root entry looks similar to
您还可以手动编辑/etc/shadow:(创建备份副本。即使你搞砸了，也要确保你能记录下来，比如在救援系统中。搜索“根”。通常，根条目看起来类似于
root:$X$SK5xfLB1ZW:0:0...
There, delete the second field (everything between the first and second colon):
在那里，删除第二个字段(第一个和第二个冒号之间的所有内容):
root::0:0...
Save the file, and try logging in as root. It should skip the password prompt. (Like passwd -d, this is a "no password" solution. If you are really looking for a "blank password", that is "ask for a password, but accept if the user just presses Enter", look at the manpage of mkpasswd, and use mkpasswd to create the second field for the /etc/shadow.)
保存文件，并尝试以root用户身份登录。它应该跳过密码提示。(就像passwd -d一样，这是一个“无密码”解决方案。如果您正在寻找“空白密码”，即“询问密码，但如果用户只是按Enter，则接受”，请查看mkpasswd的manpage，并使用mkpasswd为/etc/shadow创建第二个字段。
