David,
I just found out that you're a writer! This home network problem is really, really frustrating for me. I bet you could write an article for boneheads like me that would sell in a millisecond. Or write a _short_ home networking book and have O'Rilley publish it...I would already own that book if it existed. I imagine there are lots of M$ users who want to be Linux users, but who are frustrated (or defeated) by simple things like their home network.
What you wrote me below is THE ONLY mention in any of the articles, books or newsgroups I've read that the "IPs on different subnets" are supposed to be _different_. In fact, both of the Linux books I have don't address networking hardly at all. They tell you to use the wizards (which no one needs instructions for) and they assume that everything works out perfectly. One of the books even has a quaint metaphor about the mailman delivering your mail, as though that's what you need to understand in order to get your network to work.
There are so many different terms and different settings involved that I am just completely confused.
If you were to write about this, I'd suggest defining what all these terms mean, and how they relate to each other:
SSID bridge Hosts (which have an IP, a name, and an alias - who knows why) DNS Hostname (which seems to have something to do with DNS) network name Domain name Gateway DHCP IP Address TCP/IP Subnet Mask subnet
All of these can be set differently througout the network (desktop, router, and laptop), and I have no clue as to how they are supposed to fit together - even though you have kindly sent me three emails already, which I'm sure would make perfect sense to someone more experienced than me.
The number of possible configurations seems endless, and no matter what I do, Konqueror gives me the "Cannont connect to host localhost" error message. I have run all the wizards over and over trying to get the machines to do the work themselves, but to no avail.
I would make one other suggestion for this hypothetical handbook: teach us how to do all of this from the command line, because one of my books describes linuxconf, which I don't have, and the other one assumes that KDE is always flawless. I like working from the command line - I want to lean how to do everything from the command line.
I really appreciate your time, David - I hope that someday I can start helping people here, rather than just asking for help!
Peace,
Tom

Not the info I needed.
Unless your router had the Desktop and Laptop (Wireless) interfaces bridged, you need different subnets on those two interfaces.
------------ | Internet | ------------ | ------------ | Router | ------------ ______________|A |B | | ---------- | ---------- | Desktop | ------| Laptop | ----------- ----------
OK, let's assume your router connection (eth0) to the Internet is good. Then you have Interface A (eth1) connected to your desktop. You have Interface B (wlan0 or eth2) connected to your laptop.
A and B, unless you are running a bridge, must have IPs on different subnets: A: 192.168.0.1 with Destop 192.168.0.2 B: 192.168.1.1 with Laptop 192.168.1.2 each address above uses netmask 255.255.255.0 w/ broadcast at xxx.xxx.xxx.255
This also makes masquerading (SNAT) to the Internet easy: iptables -t nat -A POSTROUTING -s 192.168.0.0/23 -o eth0 -j SNAT --to-source xxx.xxx.xxx.xxx
This help?
David,
Thank you again!
I found more about the router: Channel = 6 WEP encryption disabled
Not relevant
The laptop:
In the Network Configuration tool the DNS tab contains this info: Hostname = wireless Primary DNS 192.168.2.1 Secondary DNS = [blank] Tertiary DNS = [blank]
worry about DNS later. Get basic networking working first.
In the KDE Control Center, Network > LAN Browsing settings: LISa daemon Scan these addresses 192.168.2.2/255.255.255.0 Trusted addresses 192.168.2.2/255.255.255.0 Broadcast network addresses 192.168.2.2/255.255.255.0 ResLISa daemon Trusted addresses 192.168.2.2/255.255.255.0
