Hello, apologizes up front if this has been asked before - Google's EE site search turned up nothing after 14 pages of looking! Ugg. Also, first post here (be gentle)...
I am new to Linux but I was a beginner UNIX admin type about 4 years ago - a bit rusty.
I have a Home network that looks like this:
Internet --> Cable Modem --> LinkSys Wireless Access Point Router with 4-Port Switch (Model BEFW11S4) --> 3 desktop machines
Currently all 3 machines are _wired_ to the hub, so the wireless part is out of the picture. The three machines are:
192.168.1.101 - P4 2.4 GHz running WinXP
192.168.1.102 - P1 133Mhz running RedHat Linux 8 - vanilla install from CD
192.168.1.103 - Pentium Celeron 500 running WinXP
All three machines are getting IP addresses via DHCP and when I log into the router (192.168.1.1) it shows them all in the DHCP table.
I am running Linux in line (server) mode.
I have configured apache to run on the Linux box Listening to Port 80 (http) and 443 (https) and from that same box I can telent to port 80 and type GET / HTTP1/1.1 (or what ever the command is) and it pipes out the index.html contents to my screen.
From the WinXP machines using IE I cannot browse to http://192.168.1.102
I can ping the Linux box using its IP address from both WinXP machines. Telnet is not running on the Linux box so I cannot telnet to it from the WinXP machines. Tonight I will start telnetd and see if I can get to port 80 via "telnet 192.168.1.102 80" and see if that works. I will add comments then.
In the mean time....
If I can telnet to port 80 and get a response from "GET /" but still cannot browse to port 80, what should I be looking at? The browser settings??
If I cannot get any response from telnet from another box what should I look at? Router firewall? Linux Firewall? I did not see ipfilter running by looking at the output from "netstat -r" - but I am not exactly sure what I'm looking for.....
Also, what should be in the /etc/hosts file? I want to get this to work locally first, but will eventually open port 80 on the router and use DynDNS to point to my Linux box to serve up a domain name that I own....
Any clues or debugging steps would be greatly appreciated...
