Hi:
I can log in the target ftp server with any user/password after I
included the ftp server component from tornado, but can't log in any
more after I include the ftp server security component. I wonder if
someone could tell me how to config the ftp server, so i could log in
with a specific user and password, and with limited rights.
Thank you!
Hi:
If you turn on security ( ), then you've asked ftpLib to use loginLib
to verify users. It has it's own user/password validation mechanism,
or you can add your own for customer features by replacing their login
validation function.
LC
-> loginUserAdd "peter", "RRdRd9Qbyz"
value = 0 = 0x0
-> loginUserAdd "robin", "bSzyydqbSb"
value = 0 = 0x0
-> loginUserShow
User Name
=========
peter
robin
value = 0 = 0x0

Hi:
Thank you!
But how to set the user rights? If everyone login my ftp has the
rights to delete, it's a disaster.
Hi:
I don't think there is a way to use the loginLib to alter "rights" for
ftp. You can write your own user verify functions using loginLib and
ftp will use that to verify, but I don't see how you'd return "rights"
unless you modified both loginLib and ftp. You normally don't get
source for either of those.
You may want to consider alternate means of protecing critical files -
maybe a separate flash partition protected with jumper or locking
sectors, etc.
I think most of the protection that FTP affords is provided by the file
system, not FTP directly. You can try something like (in the shell)
attrib "iot.dat","+RS"
[cpu0]->ll
-r-xr-xrSx 1 0 0 2266407 Jan 1 1980 iot.dat
-rwxrwxrwx 1 0 0 30720000 Apr 18 2006 iot1.dat
-rwxrwxrwx 1 0 0 81920000 Apr 18 2006 iot2.dat
But that will affect all users. I don't thing the dosFs file system
supports the definition of ownership that you are looking for. Might
work if you restrict shell access.
Good luck,
lc
Thank you every much!
