I have added a 4th NIC to my setup, and want to set up wireless. I have stared at the configuration Tom has for the last week, and my eyes are crossing. eth0 "net" goes to my internet connected firewall with a 192.168 address eth1 "loc" goes to my switch connected to local switch also 192.168.x eth2 "work" goes to my office with a 172. address eth3 Trying to

I have a 501 with traditional power and a 301 with PoE. I rightfully assumed that the traditional power from the 501 would work on the 301. How do I get the PoE to work? Do I use the Polycom PoE cable in addition to whatever PoE injection method I use? I have a Cisco PoE injector that works on my Cisco AP350 and my 7960. No combination of this injector, the Polycom cable, and the phone result in

Hi, I have 2 interfaces - one for adsl and other for LAN on my Linux gateway machine. The IP addresses are 10.10.10.3 & 192.168.10.101 respectively. Now my routing tables show this particular entry. What exactly is this? 169.254.0.0/16 dev eth0 scope link Or by traditional route -n, 169.254.0.0 0.0.0.0 255.255.0.0 U 0 0 0 eth0 What exactly is this 169.254.0.0/16

I''ve got a linux router pushing 600-1000 pppoe connections through it. I''m getting a screen error "Neighbor Table Overflow" after this box has been up for between 1 week and 1 month. When this is happening, routing slows to a crawl if at all. Then dies. I''ve added: # Added to stop "neighbor table overflow" messages in the kernel

* sorry for the other schema, it came out a mess. I hope this one is understandable. hi: I have this 2 boxes set up like this: 2020::2/128 2020::254/128 3030::254/128 192.168.0.2/24 192.168.0.254/24 192.168.30.254/24 +-------+ eth0 eth3 +-------+

I''m giving up on an old model Cisco AP350 (it was installed on the internal LAN) and installing a Linksys BEFW1154 v4 "Wireless-B Broadband Router" for my home setup. The settings do not seem intuitive when integrated with Shorewall. It seems to me that someone had done a write-up for this Linksys box, but I can''t seem to find it in the documentation. Is

Hi, I have a linux router with 4 ethernet cards; eth0 through eth3. Basically, all I want to do is route all traffic from eth2 to eth0, and all traffic from eth1 to eth3. I''ve looked through the LARTC how-to, specifically at chapter 4, about multiple providers. However, I am still a bit confused, and not sure how to set up my routing tables, as my scenario differs from the one in the

Hey all, A while ago today I posted about not being able to get my two interface setup working with a router (di 652 wireless/wired). I recieved help from Tom and got everything in the router turned off and set it up as a switch rather then a rouiter, this still never corrected my problems. Use tcpdump I see there is alot of traffic, but as soon as I dhcpcd eth1 (local) I loose all outside access

Hi, I'm building a firewall/router on Centos. I'm using Shorewall but have currently stopped and cleared the firewall rules to isolate the routing problem. My firewall box has 5 interfaces in it but currently only two are involved in the problem. eth1: inet addr:192.168.1.224 Bcast:192.168.1.255 Mask:255.255.255.0 eth3: inet addr:192.168.202.1 Bcast:192.168.202.255

Hi xen users, I''d like xen0 to be the controller and xenU(1) to be a firewall/router with 4 subnets (WAN, LAN, DMZ, TEAM) each with 1 of 4 physical nics attached to it. Using FC4 with xen-3.0.0-7 with linux kernel 2.6.12.6, default make world configurations, box is athlon cpu, 512M, 4 nics. On boot all nics are recognized, lspci shows them to be present. In xenU there are four ifcfg

I have a setup with two Internet providers. One circuit (net0 == eth1) is used primarily for employees and tunnels to other sites. The other (net1 == eth2) is for the production machines that customers access. Everythung works in teh sense that packets get to where they are sent (mostly) but I recently I had a sniffer on the system and noticed a problem I cannot solve. traffic coming in

Hi all I started playing with tcng to generate my tc rules, but I have some difficulty implementing my rules... The script below generates an error: # Device eth0 tc qdisc add dev eth0 ingress beginner.tc:2: don''t know how to build meter for this The script is below, I changed the real IP numbers for XXs and YYs, since it doesn''t really matter what they are. eth0 is the

Hi, In a routed network environment, without the router , we want to use the shorewall as the firewall/router. The ISP has assigned the following set of IP addresses. WAN IP for subnet 1 (DATA) 220.227.202.X/30 ( to be assigned to eth0 of the shorewall) WAN IP for subnet 2 (Voice) 220.227.202.Y/30 ( to be assigned to eth1 of the shorewall) Addresses assigned for Subnet 1 by

I was given the challenge recently of creating a LAN-LAN bridge between two buildings several hundred metres from each other, using only existing Cat 3 wiring and without having to resort to an expensive and finicky 5 Ghz wireless link. I was able to create a 90 megabit link for about $3,000 Cdn with new PC's, CentOS 4.1, and the newly avaliable Black Box VDSL Ethernet Extender, which

Hi, I have a suspicious problem with multiple uplinks configuration. First of all my configuration: 1) kernel 2.6.20.3 2) iptables 1.3.7 3) last iproute (for masked marks) All wan interfaces are bridged (stp disabled) in only one interface (wan0), all lan interfaces are bridged (stp enabled) in only one interface (zlan0). The wan0 bridge is to allow UPnP works. To allow related

Hi all I have about 10 folders in my directory i.e Folder 1 – Folder 10.

Does anyone know about some free (as in beer, and maybe as in speech) software which would implement authentication and authorization of a user prior to issuing a valid dhcp lease? I imagine the following scenario: someone walks into my office building with a laptop (a colleague, a visitor, a guest, whoever), and hooks up onto the local net (wired or wireless). The server detects an unknown

Hi all, I''m having some problems setting up qdiscs on a bridge.The config looks a little like this: ifconfig ifb0 up # Bring up the IFB for this bridge. tc qdisc add dev eth2 ingress tc qdisc add dev eth3 ingress tc qdisc add dev ifb0 root handle 1:0 cbq bandwidth 100Mbit avpkt 1000 cell 8 # Raw qdiscs on each bridge port tc qdisc add dev eth2 root handle 1:0 cbq bandwidth

Hi, I'm on a Dell VEP 1405 running Debian 9.11 and I'm running a few tests with various interfaces given in PCI passthrough to a qemu/KVM Virtual Machine also running Debian 9.11. I noticed that only one of the four I350 network controllers can be used in PCI passthrough. The available interfaces are: *# dpdk-devbind.py --status Network devices using kernel driver

Hi I have come across a problem, with my tdp410 and soekris board (basically pc on a chip amd geode cpu). I am using the box as a firewall/asterisk box.
