Hello Edward, Wednesday, February 20, 2002, 4:41:54 AM, you textually orated:
ED> Just something that's always evaded my comprehension. ED> I always use the 192.168.0.0 - 192.168.255.255 range for internal networks. ED> Usually the first 9 reserved for servers (.1-.10) and the rest clients. From ED> all the documentation I've read this is a Class B network (16 bit), and to ED> use it I should netmask 255.255.0.0. Any documentation that states this is a class B network is wrong. It is a class C. Here is the breakdown... Class Netmask Network Addresses A 255.0.0.0 0.0.0.0 - 127.255.255.255 B 255.255.0.0 128.0.0.0 - 191.255.255.255 C 255.255.255.0 192.0.0.0 - 223.255.255.255 These are the defaults. ED> I was at a customer's the other day who uses the 192.168.1.x range. I put a ED> pre-prepared Linux box (RH7.2 if it matters) down there, with my usual ED> 192.168.0.1 ip set-up, but the clients just would not connect to it. Not ED> even ping it. The client's netmask WAS set to 255.255.0.0, so my question is ED> this: ED> Can a client at let's say 192.168.1.x with netmask 255.255.0.0 connect to a ED> server at 192.168.0.1 with netmask 255.255.0.0? Yes. But there is usually an extra step to override the defaults. ED> I've never pondered this before because as I said, I normally use the ED> 192.168.0 range only, but in this case, I had to change the server to ED> 192.168.1 range to make it work, when, from what I understand, I shouldn't ED> have had to. In the end it's all good and works, but why not with the ED> 192.168.0 range? I realise it's a different sub-net, but the mask should ED> take care of that no? I believe that you need to change the default network boundaries to get it to route properly. Something like... route add -net 192.168.0.0 netmask 255.255.0.0 eth0 It may also be required to have ip-fowarding enabled as well. Have fun, -- _________________________________________________________________ Brian Ashe CTO [EMAIL PROTECTED] Dee-Web Software Services, LLC. http://www.dee-web.com/ ----------------------------------------------------------------- _______________________________________________ Redhat-list mailing list [EMAIL PROTECTED] https://listman.redhat.com/mailman/listinfo/redhat-list
