maximum links from site to site on same server

[capsmaster]

Hello guys first post here. Let me first say that I have found your forum to be very useful for the short time that I have been reading. Now for the question. How many different websites can link to eachother on one server before google gives me a penalty? I have about 30 urls that I would like to use and get good seo results but need to know how many different servers I am going to have to get for this project. Any good guesses would be appreciated.
Thanks

Have no idea on the maximum figure, if all the url's is on seperate ip's for each domain, you will probably be fine, if they are all on 1 domain, and there is no other domains on that ip except yours, i think there is quite a big chance you will get some kind of penalisation.

I also have no idea of the maximum figure, but I have also about 30 URLS which are linked, but not every page contains a link to every other page. There are about 5 links on every page, which point to 5 other domains.
Can't see why this shoud be penalised. For me it is working fine but again: don't carry it to excess. Massive cross linking will receive a penalty for sure!

If each of these urls contain unique content and you have a good mix of incoming links from other sources you should be fine.
