it shouldnt take long at all - u must have something up with your networking config.
are u using a gigabit switch to connect the two? or a router? perhaps your router settings are incorrect, or you are using a 10/100 router.
if u are having such problems just redownload it directly on the g4 from the source u originally downloaded it from. the mdd definately has gigabit ethernet of course.
i thought id shared files from snow leopard or Leopard/Tiger to mac so 9 before
i forget how to do it lol because i use my nas4free server which has netatalk AFP
and it works beautifully
when all else fails .. just use FTP.. set up the g5 as a ftp server with system preferences and connect from the os9 machine with an ftp client
thats what i would do if i didnt have a fileserver
which osx is on your g5?
if its tiger u can try this:
http://www.hornware.com/sharepoints/might work in panther? ok they have diff version of sharepoints for each osx revision.
SharePoints is an application or a preference pane that makes it easy to add and delete share points like in the old Finder. In Mac OS X, by default, you are limited to sharing only what is in your public folder in your home directory. This program makes it easy to share any folder.
In addition SharePoints also brings back users and groups management to Mac OS X as well as easy configuration of AppleFileServer (AFS) and Samba (SMB) Server properties.
i just tested the above from os 9.2.2 to tiger 10.4.11 and it works 100%
u can connect to the share from os9 by going to apple menu > chooser
and typing the ip (Which u can observe on the g5 in the system preferences > network) and it will prompt u for username/pass to connect as, and then display the shares that u have access permissions for.
just make sure to enable the shares "AFS" applefileserver pulldown menu from disabled to enabled in sharepoints... u hit browse to select the folder u want to share in sharepoints and it it does all the hardwork for u when u hit "update share"
