networking five macs with osx

Submitted by rummelAIO on February 10, 2006 - 4:56pm. Unix and Mac OS X

ok, here we go...first note is that i have only done very minimal networking, ie: three macs sharing one internet connection through a router.

the story goes: in my studio, there are two ibooks(no wireless yet), one powerbook(airport), two digital audios g4s(wired). i have the two g4s and the powerbook linked to the router, and share the internet connection. what i want to do is, have just the two g4s and the powerbook continue to share the internet as well as share a networked hard drive. the part i dont know how to do is let the two ibooks share the hard drive but have absolutly no access to the internet.

should i do two differnt routers, or is there a network setting that can allow this. all five need to share the hard drive, but the ibooks must not access the internet.

any help would be awesome.

peace and love
ande

im not completely sure how to

im not completely sure how to physically hook them up, i'd say hook all up to one router, then on the 2 ibooks make a user for each (aside from the administrator) that have access to the hard drive, but not to the internet.
hopefully this makes sense

DHCP

Submitted by makillik on February 10, 2006 - 6:43pm.

One thought process is to give the 2 iBooks static IP's and the others DHCP addresses

Example
if the router is 192.168.0.1
and assigns IP addresses in the 192.168.0.100-192.168.0.200 range
set the iBooks to have an ip address of 192.168.0.2 and 192.168.0.3

good luck Eye-wink

That should do the trick; the main thing is to keep the iBooks from knowing where to find a DNS server and router. So when you set up the static IP's for those two just leave the DNS and router fields blank. Without those two pieces, they can still access everything on the local network (within the same subnet) but can't find their way outside of it.

got it

Submitted by rummelAIO on February 10, 2006 - 8:39pm.

ok, i did tghe static versus dhcp. the powerbooks and g4 are within the routers IP range and the ibooks are far out of that range. result= all comp locate aechother and only the three can play on the internet. i am so glad you guys knew this. i knew there was a way to do it just had no clue how.

after i set the topic, i went rumaging through the router, found a setting for filtering certain IP address. i tried that and that did block the internet but also made the system sluggish. but the static v. dhcp worked out great.

thenks

One last thing...

Submitted by ax0n on February 11, 2006 - 8:18am.

Keep in mind that if your intent is to keep users of those iBooks off the internet, you'll need to lock the preferences, because anyone (especially kids) with a little know-how can either assign a DNS and router address manually, or switch it to use DHCP.

Voila. Instant interweb access for the iBooks.

If it's just because the iBooks are used for non-internet tasks and you don't want them "phoning home" or accessing the internet without your knowledge, it's not as big of a deal. It's just that there's a big difference between "making the computer not access the internet" and "making sure a user of the computer can't access the internet".

Computers operate on rules set by humans. As long as no other humans are changing the rules for that computer, you should be okay.

good point

Submitted by rummelAIO on February 13, 2006 - 2:33pm.

not that i think the sales ladies will have any knowlwdge to change the settings, but i will make note of it.

but the main reason is so the software used for the studio does not "phone home".
