※ 引述《"cindy" <[email protected]>, 看板: FreeBSD》之銘言：
: 如何更改設定, 才能讓 adduser username 超過 16 個字元呢?
: 因為如果直接 #vipw 去更改帳號 , 更改 /etc/group 的帳號, 以及 /home/帳號.
: 但使用 passwd 帳號 , 就沒法更改密碼.
: thank you.
man adduser
username
Login name. The user name is restricted to whatever pw(8) will
accept. Generally this means it may contain only lowercase char-
acters or digits. Maximum length is 16 characters. The reasons
for this limit are historical. Given that people have tradition-
ally wanted to break this limit for aesthetic reasons, it has
never been of great importance to break such a basic fundamental
parameter in UNIX. You can change UT_NAMESIZE in <utmp.h> and
recompile the world; people have done this and it works, but you
will have problems with any precompiled programs, or source that
assumes the 8-character name limit and NIS. The NIS protocol
mandates an 8-character username. If you need a longer login
name for e-mail addresses, you can define an alias in
/etc/mail/aliases.
