Hi,

the board I use is BF518F-EZBRD,I want to set a passwords for the telnet so that when I use telnet to login it required check the username and passwords,frist I build the kernal like this:(from docs.blackfin.uclinux.org/doku.php?id=faq&s[]=telnet&s[]=login)

1. In Blackfin uclinux enviroment, use passwd to modify root passwd. and copy the generated etc/passwd file to your uclinux-dist/vendor/AnalogDevices/<board>/passwd, so you know what the root passwd is. You can also add other user names in this file.

2. modify uclinux-dist/vendor/AnalogDevices/<board>/inittab, add one line:

ttyS0::respawn:/bin/getty -L ttyS0 57600 vt100

3. Unselect [Customize Vendor/User Settings] -→ [Core Applications] -→ [enable console shell]. Remove any binary and object files in folder uClinux-dist/user/init/.

4. ~/your-uClinux-dist/> cd user/init

~/your-uClinux-dist/user/init/> make clean

5. Select Customize Vendor/User Settings] -→ [tinylogin] → (login,getty,passwd,su etc.). Build kernel.

6. ~/your-uClinux-dist/> make

7. ~/your-uClinux-dist/> cd romfs/bin

8. ~/your-uClinux-dist/romfs/bin/> ln -s tinylogin getty

9. ~/your-uClinux-dist/romfs/bin/> ln -s tinylogin login

10. ~/your-uClinux-dist/romfs/bin/> ln -s tinylogin passwd

11. ~/your-uClinux-dist/romfs/bin/> cd ../../

~/your-uClinux-dist/> make image

but when I run 'ln -s ',it appears that :

root@ubuntu:/home/uClinux-dist/romfs/bin# ln -s tinylogin getty

ln: creating symbolic link `getty': File exists

root@ubuntu:/home/uClinux-dist/romfs/bin# ln -s tinylogin login

ln: creating symbolic link `login': File exists

root@ubuntu:/home/uClinux-dist/romfs/bin# ln -s tinylogin passwd

ln: creating symbolic link `passwd': File exists

why?how to solve this problem？
