Chapter 6 Solving Problems 93
• See if there are any problems with directory services, and if the directory services
server is operating and connected to the network. For help with directory services,
see the Open Directory administration guide.
• Verify that IP filter service is configured to allow access to the appropriate ports. If
clients still can’t connect, see if the client is using FTP passive mode and turn it off.
Passive mode causes the FTP server to open a connection to the client on a
dynamically determined port, which could conflict with port filters set up in IP filter
service.
• Check the /Library/FTPServer/Messages/error.txt file for clues as to what the problem
might be.
Clients Can’t Connect to the FTP Server
• See if the client is using FTP passive mode, and turn it off. Passive mode causes the
FTP server to open a connection on a dynamically determined port to the client,
which could conflict with port filters set up in IP filter service.
Anonymous FTP Users Can’t Connect
• Verify that anonymous access is turned on.
• See if the maximum number of anonymous user connections has been reached. To
do this, open Server Admin and click FTP in the Computers & Services list.
