  • 1. add route pass traffic
    Hello All, I have 2 servers, server A and B and I would like to add a route to serverA that will pass all traffic from serverB to one if serverA's interfaces ? Not sure of the syntax though...Any suggestions please... Thanks,
  • 2. IPv6 Questions
    I am trying to figure out which way the industry is going with regard to configuration of hosts. Are DHCPv6 and SLPv2 alternatives or are they complementary? If they are alternatives in doing the same thing, which one is more commonly used? Also, under IPv6 is the BOOTP protocol the preferred way to net-boot? I don't see an option under DHCPv6 to provide the name or address of a boot server. thanks, Paul
  • 3. How to ping from a wlan client to another wlan client
    Hello, I have a asus wl-600g router (linux os inside). All is working fine (each client see the router and can reach the web) but from a client on the wlan I can't reach others clients in the wlan, so the router doesn't route. This is the network: CLIENT 1 -------> ROUTER - Ping ok ROUTER --------> CLIENT 1 - Ping ok CLIENT 2 -------> ROUTER - Ping ok ROUTER --------> CLIENT 2 - Ping ok BUT CLIENT 1 <----------> CLIENT 2 - Ping doesn't reach Lan config: default gw: 192.168.1.1 mask: 255.255.255.0 route table on the router: Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface 213.205.24.97 * 255.255.255.255 UH 0 0 0 ppp_8_35_1 192.168.1.0 * 255.255.255.0 U 0 0 0 br0 default 213.205.24.97 0.0.0.0 UG 0 0 0 ppp_8_35_1 LEGEND: br0=lan and wlan ppp_8_35_1=wan What should I do to allow each client to see other wlan clients on the lan?

    Hi, Any one tried to set packet filtering on the ethernet interface driver ? what i'm trying to set the source address filtering not by netfilter, just on the ethernet interface drivers. thanks in advance. Cheers.

two dsl connections, two routers, dual nics on linux box , want to run two websites

Postby laitkor » Mon, 21 Jun 2004 03:58:19 GMT 

Hello,

I have two dsl connections, with one public ip on each. I have a linux
box with two nic cards.

xx.xx.xx.xx(WAN)---ROUTER(LAN23.123.45.110) ---- MYLINUX
(23.123.45.107) eth1
yy.yy.yy.yy(WAN)---ROUTER(LAN192.182.1.1)   ---- MYLINUX
(192.168.1.100) eth0

I have apache listening on both interfaces. 

Problem:

1. How do I make the packets route back to the gateway from which they
originate.

Currently the gateway marked as "default" is able to serve content
from the apache. The other one cannot.

I tried adding static routes, but that didn't work.

Any help is appreciated.

Thanks
Jay

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:

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
IGMP/MULTICAST PACKETS BEING FORWARDED THROUGH THE LINUX BOX?

Here is my setup:

                               Linux Box with two NICS
PC1         router          NIC(eth0)---NIC(eth1)          router
 PC2
192.168.1.100 192.168.1.1 192.168.1.111 192.168.4.114 192.168.4.1
192.168.4.100


Linux Box:
---------
/proc/sys/net/ipv4/ip_forward


PC1
----
ping 192.168.4.1 - works
ping 224.0.0.1 - only get reply from 192.168.1.1 and 192.168.1.111


PC2
----
ping 192.168.4.1 - works
ping 224.0.0.1 - only get reply from 192.168.4.1 and 192.168.1.114

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

Mark

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
