ftp file prompt when try to remove

[mohdamir]

Hi Gurus,
There are a few files in my directory as below:
# ll
total 3060
-rw-r--r-- 1 cdisime ftponly 1566720 Sep 9 09:32 sudo-1.7.1-ia64-11.23.depot
-rw-r--r-- 1 cdisime ftponly 0 Sep 9 10:14 test123
-rw-r--r-- 1 cdisime ftponly 0 Sep 9 10:14 test456
-rw-rw-rw- 1 root root 0 Sep 9 10:20 test789

I used another user id, then try to remove test789. I can. But when I try to remove ftp file, test123 and test456, it prompt the message below:
rm: remove write-protected regular empty file `test123'?

What should I do to remove these files without the system prompt the message?

TQ
