1. 如何限制某个用户只能FTP不能TELNET?[zz]
很简单,修改此用户的shell即可。打开/etc/password,查找要修改的用户所对应的记录,如:
          在我的hiweed中,是/etc/passwd
floatboat:x:500:500::/home/floatboat:/bin/bash
  要禁止floatboat用户登录,只需要把此行中的“/bin/bash”改为/usr/bin/passwd即可。这样用户telnet上服务器只能修改密码,而无法直接控制台。
  当然,如果你希望连密码都不允许此用户修改,只要把shell改为“/sbin/nologin”即可。
