[HP-UX] ftp無法登陸

HP Unix ftp無法登陸，檢視/etc/inetd.conf檔案.

[root@xxxxxx:/xxxxx#] more /etc/inetd.conf
ftp          stream tcp6 nowait root /usr/lbin/ftpd     ftpd -l -a
login        stream tcp6 nowait root /usr/lbin/rlogind  rlogind
telnet       stream tcp6 nowait root /usr/lbin/telnetd  telnetd -b /etc/issue

ftpd 這行有個-a的選項時,則ftp時會呼叫/etc/ftpd/下的配置檔案ftpusers.
[root@xxxxxx:/etc/ftpd#] ls -l  #裡面的資料夾都是空的.
total 0
dr-xr-xr-x   2 bin        bin             96 Oct 2  2013 ftp-exec
dr-xr--r--   2 bin        bin              96 Oct 2  2013 pids

將/etc/inetd.conf的ftp行的 -a選項去掉後重啟 inetd 服務後正常
[root@xxxxxx:/xxxxx#] more /etc/inetd.conf
ftp          stream tcp6 nowait root /usr/lbin/ftpd     ftpd -l
login        stream tcp6 nowait root /usr/lbin/rlogind  rlogind
telnet       stream tcp6 nowait root /usr/lbin/telnetd  telnetd -b /etc/issue
[root@xxxxxx:/xxxxx#] /sbin/init.d/inetd stop
Internet Services stopped
[root@xxxxxx:/xxxxx#] /sbin/init.d/inetd start
Internet Services started
