Now - after you have added it, try to write:
passwd user
to change the users password.
After that try to login as "user" with your new password, using ssh - and if that works, ftp should work as well.
Yes, it works fine, but only till next reboot - my /etc/passwd returns always to its original after reboot - I tried flashfs save/commit/enable but with no success. How can I save the /etc/passwd file so that it is permanently modified? (Oleg firmware WL500gx-1.9.2.7-7b)
Thanks in advance
