Network settings and security

[LispWarez]

is there a standard for network settings and security atm? u cant just have randon IP addresses for each access point (and i mean like 192.168.x.x or 10.x.x.x) surely u gotta stay in one class for them all to link up. and the security aspect to all this?? u dont want every single user on the network to have access to ur PCs? if there is no standard atm maybe we should set one...

ideas?

The only public IP address is the 192.168.x.x range. All other IP addresses are registered IPs from the internet.

you can split a network by using the subnet address, this is quite advanced and you'll need routers. Subnet calculations will also need to be done. Im not 100% sure on this point.

If you dont want people to access your PC, the best solution is a firewall.
Wifi security can be done by using the WPA or WEP encryptions

Well if I do understand u correctly the network we use to work on was a slash 30
IP 10.0.11.2/30
SUB 255.255.255.252
G 10.0.11.1

So the next IP will be
IP 10.0.11.6
Sub 255.255.255.252
G 10.0.11.5

There's private IP address subnets in each network class:
10.0.0.0/8
172.16.0.0/12
192.168.0.0/16

(Just worked it out with windows calculator, die CIDR parts may be wrong).

Our wireless network is currently running on the class C addresses (192.168.x.x). But it wouldn't be difficult to interconnect networks rather using class A and B addressing schemes.

The only no-no is IP duplication, stay within the allocated private IP ranges, and try not to use another wireless network which you intend to connect to at a later stage's, IP address.

Can I suggest we start up a registry with IP ranges that people intend using as part of the mesh?

This would make planning new systems a lot easier as well as getting existing systems running more efficiently.

Just an idea...

There is a whole range of private IP's u can use. I wouldnt worry about that. :p As solar sort of pointed out all you have to worry about is not duplicating a IP. From a security point of view it would be best to start off with a /26 which will give u 62 addresses that u are able to assign. Too many IP's = 2 many routes = havoc for the guys who are not to sure bout TCP/IP %-6

It all depends on what you want to do. Do you just want to connect to your friends to play games and swap files? Or do you want to build a free wireless network covering the Cape Town area? If the former than I agree with you - there are lots of IP's to go around. If the latter than we need to be a lot more carefull about how we do this.

[MuffenMan]

I would opt for a free wireless network covering the whole Cape Town. If we do so, couldn?t we maybe use a DHCP server (or do i have the wrong idea going)

Or even maybe start a IP section on this web page?

Why don't we have a page like Jawug with all the IP allocations?
On the Jawug page i see they have allocated a ip-range for cape town
