Re: How to suppress ftp code '230 (username) logged on'

[rob@xxxxxxxxx]

Two points to this.  Read both.

First,  I goofed.  Instead of changing message TCP11AF in message file 
QTCP/QTCPMSGF (and any other NLS libraries you may have loaded) from '230 
&1 logged on.' to '230 User logged on.', I accidentally dropped the 230 
part.  This locked all users out of ftp.  The 230 is required by the RFC's 
etc.

Second point.  If you want to cause major grief for any client accessing 
ftp instead of one you created you can go ahead and make a change like the 
above.  Then in your custom written client you can violate this RFC and 
make this perfectly acceptable.  Maybe even change the 230 to a 530. 
Granted it is a little like 'security by obscurity'.  Personally, I think 
the exit points are a better way to handle security.  But enforcing your 
client may help in those cases in which you want to ensure a certain 
action is performed in a certain sequence.
