1.Two NICs, Two networks, secure websites
Hi!
I have a Cisco router (provided by the ISP) that offers 29 usable IP's.
One of the public IP's is set to be the WAN IP of a simple SOHO
Linksys router that then creates a private network 192.168.1.0. There
is a Linux server with Apache on the private network. Port forwarding
on the Linksys router allows SSL access to secure web pages,
unencrypted HTTP, SSH, etc. to the Linux server. This all is working
OK.
I need to have a 2nd SSL site running on the same Linux server. So, I
installed a 2nd NIC and connected it to the Cisco router and used one
of the available public IP's. I cannot connect to the new public IP
(via the new NIC), but can still connect to everything described in the
1st paragraph above.
I can ping out each of the interfaces (e.g. ping -I eth0 yahoo.com and
ping -I eth1 yahoo.com both work). The results of route are:
Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use
Iface
AAA.BBB.CCC.160 * 255.255.255.224 U 0 0 0
eth1

lo
default 192.168.1.1 0.0.0.0 UG 0 0 0

On the server, I can do lynx https://192.168.1.2 and lynx
https://AAA.BBB.CCC.164.
>From outside of the server, https://AAA.BBB.CCC.163 works now, but
https://AAA.BBB.CCC.164 does not. What needs to be done to allow
https://AAA.BBB.CCC.164 to work? And/or, what can I do to troubleshoot
the problem?

2.Forwarding of multicast packets between two subnets with two NICS - Does not work
WHY DO I NOT GET ANY REPLY FROM A DIFFERENT SUBNET? WHY ARENT

ping 192.168.4.1 - works
ping 224.0.0.1 - only get reply from 192.168.1.1 and 192.168.1.111

3.Connecting two networks with two linux boxes.
I have 2 networks each with a linux box as the gateway to the internet.
At the moment they are VPN'd together, but are close enough to get a
cable run and I'd like to connct them like this to make it quicker
so each linux box will have 3 nics in it.
My question is possibly a dumb one! But what should the IP for the 3rd
nic in each box be?
The networks are:
network - linux box internal address
Box 1) 10.0.12.x/24 - 10.0.12.1
Box 2) 192.168.12.x/24 - 192.168.12.1
Should the 3rd NIC in the box 1 be on the 192.168.12.x range, and vice
versa but wouldn't that confuse the other network as it would think that
it is a local IP when it wouldn't be.
Should they both be on a different range althogether? And then set the
routing up on each.
ie 3 NICS in each
Box1
internal 10.0.12.1
public 123.456.78.2
"intranet" 10.0.13.1
Box2
internal 192.168.12.1
public 423.243.123.32
"intranet" 10.0.13.2
If it was 2 networks with one linux box it would be easy, just not sure
how you'd connect the two boxes together....
Any advice appreciated!
Cheers

4.How two bridge two DSL lines
5.Two network connections NICs not activating on Fedora 3 Linux 2.6.11-1.14_FC3
Hi,
Running Fedora kernel 2.6.11-1.14_FC3
This problem has been present since Fedora 2 (kernel 2.6 ?)
I have a generic laptop with built-in UTP LAN socket and a Netgear
802.11b PCMCIA card.
When the laptop boots, the onboard LAN is assigned eth0 and the
PCMCIA Netgear eth1 .
Both appear as Active in the Network Device dialog - even if no UTP
cable is connected to the eth0 port .
When UTP cable is plugged in, the eth0 can get DHCP IP Address from
the router and then connect out to the internet.
However, when there is no UTP cable connected but there is wireless
card that shows steady green light, the device is not connected to the
router. I have to disable BOTH eth0 and eth1 then activate eth1 (the
wireless card) to get a DHCP IP address and then an active network
connection
Is there anyway to get the NetGear wireless card on eth1 active and
usable after boot without going through all of this?
Thanks
Clive
