This may or may not be a security issue, I just don't know.

I have a Macintosh G4 Mirror Front Tower running OS10.4.8. I'm using a
Linksys (non-wireless) Router. I have no wireless devices on the
computer.

For a week now, when I open the Network icon in the Sidebar I see my
own G4 local icon and a Library Icon. After a few minutes, server icons
from other peoples computer start showing up in the list. These are 4k
aliases and cannot be opened or connected. They also cannot be deleted
because of insufficient privileges. After a restart, the list is clear
and after several minutes, more server icons appear.

My service provider states that without a wireless router this
cannot happen, so it must be an Apple problem.

Any thoughts

Any ports open? Anyone put a AP on the LAN?

I once heard of a manager who brought his own AP to work and plugged it in!

I'm not certain what an "AP" is, but There is only an iMac connected
to the same router. It's been there for over a year without this
happening. Doesn't make a difference is the other computer is turned on
or not. The same thing happens if I bypass the router and go modem
direct to the G4. My service provider stated that this can't happen
without a wireless router. I said OK, but I'm looking at it. He said,
it's not our fault, it's an Apple problem.

AP ::= wireless Access Point

Could there be anything else on your LAN?

I certainly have visibility of 20 or so other users in my locality
connected to the same cable provider. I see a lot of scanning/
broadcasts by smb and mdns - it's just noise, but a ready reminder
that most people in charge of computers connected to the internet
don't know much about security.
