Slow FTP Authentication

[Gary Lubben]

My webserver (Mac OS X Server 10.3.4 – Web, AFP, FTP all on) is really slow for ftp users to login. It takes along time for the server to authentecate the user (30 seconds to a minute). This only happened when I upgraded from Mac OS X Server 10.2.

Any ideas?

One of the things you can do is make a small edit to the /etc/xinetd.c/ftp file:

Change :

server_args = -a

to:

server_args = -aI

The extra I switch will suppress the use of RFC931 (AUTH/ident) to attempt to determine the username on the client and result in a much faster response.

This does not apply to Tiger since the xinetd system has been replaced by Launchd. In Tiger you can do the same by editing the :

/System/Library/LaunchDaemons/ftp.plist

Change:

ProgramArguments

xftpd
-a

to:

ProgramArguments

xftpd
-aI
