Networking :: Add Routing Now Different NIC Config Setting Shown
Jul 8, 2010
I have encounter strange situation I have set all my network configuration via /etc/sysconfig/network-scripts/ifcfg-eth0 ,eth0.2 ,eth1 etc .... (CentOs 5.5). I have used only once Gnome network manage settings to add routing since then all my network config change although all files mention above showing the same config I have set initially and same for Gnome network Manager.
So my server running FC4 died last night and I decided to go ahead with the long-awaited upgrade to FC10 while I was rebuilding my server. I use my server for a number of things including, but not limited to: router, firewall, web server, mail server... I have a typical configuration process that I have followed since before fedora, and it has worked well for me up through FC4, but my usual config process doesn't work on FC10.
First of all, I don't want SELinux running, I didn't see an option to not install it during the FC10 setup, so how to I properly disable or uninstall it afterwards? Second, I was unable to even configure the server to route traffic from my internal network to the web, here's the process I usually go through for this:
[Code]...
I don't have a static IP from my ISP, so I'm not quite sure how to add the default route. I think I need to do something like "route add default gw xxx.xxx.xxx.xxx eth1" where eth1 is my external NIC, correct?
What else do I need to do to route traffic? I noticed that I wasn't even able to ping my server from the internal network even though they are on the same subnet, my server's internal NIC has an address of 192.168.7.1 and my computer on the network has an address of 192.168.7.2. If I can get this going to I have internet access again at the very least, I can move forward with the web server, email, etc.

I just reinstalled Ubuntu Lucid Lynx and an old problem has come back. For some reason I couldn't fix it even in my previous installation. The problem is the top gnome panel. See the photo below: As you can see, the network icon is not shown properly while the Me menu is being shown twice. I can't even restart or log out or shut down at this situation without pressing the keystroke to turn the power off.
I never upgrade from one release to the other but rather do a completely new install. How can I keep my Gnome settings from the current release and somehow impose them after a new install. I am not sure which files/hidden files I should carry, save, possibly to a USB stick or whatever and a reasonable procedure to copy/impose them after the new install is stable.
I've got a situation where I would normally use NFS, but cannot. So in it's place I need to use a samba share (even though it's linux -> linux). I need it completely open and world writeable as if I had done an rw in an NFS export. I thought I had it as when logged in as a user I can edit delete etc. however the apache user seems to be struggling with creating files.
Here's my smb.conf as it stands. Code: [global] workgroup = WGRP server string = Samba Server Version %v security = user passdb backend = tdbsam unix extensions = no
[sites] comment = Sites Directory path = /var/www/sites public = yes guest ok = no write list = siteusr writeable = yes create mask = 0777 browseable = no security mask = 0777 directory security mask = 0777 note that the drive is mapped as user siteusr

I am trying to set up a permanent resolution in the xorg.conf file. At the moment whenever I reboot the machine the resolution defaults to auto. How I can change that to be constantly at 1600x1200?
Here is my xorg.conf file.

i know exactly what i need to do, im just not familiar enough with command line to do it properly.i have 7 computers.the first 4 are connected to a router via wireless at one end of the house. of the last 3 only 1 will be able to access the router via wireless, so it needs to share it's one wireless connection via ethernet. this computer i'm going to call 'server'server will have two IP'swlan0 192.168.1.6 this connects to the router that has internet access.eth0 i intend to have the following settingsip:192.168.0.1sub: 255.255.0eth0 will connect to a second router, where the cat5 cable goes from the server, into the internet port of the router where i will define the router's static IP:IP: 192.168.0.100sub: 255.255.255.0gateway 192.168.0.1i have then set the router IP for LAN handling as 192.168.27.1 and all ethernet connections will have a 192.168.27.x IP.
so i need to know how to, without a gui application, use the terminal to assign server eth0 a proper IP address, and tell the server to take the connection it has and share it through eth0 to supply internet for the last 2 computers via ethernet.i had it set up in this way with a windows machine being the one that had the wifi access, but i'd rather have it setup for the ubuntu server to do this task. security is imperative for these 3 remaining machines, so just getting 2 more wifi adapters for a connection to the initial router isn't an option.the 2 that connect to server do so through SSH and though server IS connected via wireless it only makes outward connections through
My setup is...I have a wireless access point using laptop as a gateway. The AP is also connected to a switch as is the laptop. So the laptop has two interfaces one wireless and one wired. A third device is using the AP to connect to a server on the internet. The AP sends the packets to my laptop where they are dropped. I've been looking for a solution to this problem without success. Basically is there a way for my laptop to forward all packets it sees from a certain IP address to whatever destination address they have?To clarify, my laptop is just the gateway of the AP and none of the packets are addressed to it at all, it just picks them up using a sniffer or similar tool.
I have a pc with debian 6 (without GUI) installed on it and want to use it as server at home. It has 2 ethernet nics. Now i want to configure the routing process. Searched internet for a long time found something but couldn't get it work.
When setting up an SSH proxy, I know you can configure Firefox to route DNS requests through the proxy. Is this possible from linux directly? I'm trying to use wget through the proxy, including DNS lookups.
I have two subnets which I am interested in connecting.
Some basic network details:
Subnet A:
Subnet B:
I am trying to think of any further relevant details, but that seems to be it to me. If I forgot anything, please tell me.
Ok the question. WHAT do I type? (Explicitly!) And WHERE do I type it? In order to reach ubuntu-01.tec.lan, or ubuntu-02.tec.lan from perpetrator.tec.lan or rapine.tec.lan?
I'm interested in using actuall ROUTES. I can already achieve results similair to this with either a NAT firewall, or with VPN.. but that's not what I am interested in.
From what I have found out so far, I should need something like the following:
I'm newbie to Wireless. Currently I try to implement EAP-TLS but firstly I need to get the hardware work, allow Access Point to Route from Wireless to Wire (LAN DNS server).
I want to use tab networking in my kvm with routing.Can any one guide me how i can do it. i have been reading different guides over the net but not understand any one clearly.I have read this[URL].. One problem is this all my server are remote and no gui is running.I am able to install kvm with ssh console with -nographic and -x "console=ttyS0" option now i want to change from bridging to tap networking with routing.And i have live ip on kvm guest/Virtual machine.
IN LAN default GW box I have a routing rule of 172.17.1.0 192.168.180.100 255.255.255.0 UG 0 0 0 eth3 that sends packets matching 172.17.1.0/24 to eth3 etc. When I ping 172.17.1.50 - it goes correctly when ping is issued in the same box (LAN GW) - falls through to default rule when the ping is done in LAN's boxes i.e. it goes to the LAN GW box and then to Internet incorrectly instead of going to eth3 and 192.168.180.100.
Is there any way of seeing why the packet matches or not the routing rules?
I have a network routing problem that I need to fix using a PC with ubuntu installed.
Here are the details of my problem: - I have two networks. - The first network is an ADSL router with subnet 192.168.1.x. I do not have access to the router nor change any of its configuration. - The second network has a subnet 172.26.x.x and connect via a wireless access point. Some of the devices connected to the network require to have static IPs. - I have a PC with ubuntu installed and two ethernet cards: one connected to the first network and the other connected to the access point. - I need to share the internet connection between the two networks using ubuntu. I already tried before on windows and the sharing worked when both networks were configured to use the same subnet. Once I changed the subnet of the second network, internet sharing stopped working.
Im having a issue with routing internet traffic from my router two different subnets (vlans).
Theres my setup:-
Server:
Both eth0,1 are running dhcp (two scoopes) that works fine!
The output of route -n is:
I have ip_forwarding on aswell, but i can ping the ip on the server running that dhcp scoope ie ping 192.168.4.1 works great but i just cant get the internet on the clients.
I have two linux boxes running RHEL 5.5 with internal ip addresses 10.0.0.114/24 and 10.0.0.118/24, and usual gateway 10.0.0.1. There's an apache listening on both ports 80 and 443 for several websites. This works nice, but the feature for load balancing has to be added. For this, externally, but in the same subnet, a hardware device has been placed for load balancing (we call it "F5"), with internal ip 10.0.0.152 (vrrp for 10.0.0.153 and 10.0.0.154). There's a service address that does NAT via round robin to the servers, 10.0.0.208, managed by the F5 balancer.
If I set as gateway the ip 10.0.0.152 in both nodes, I can use the service address for browsing http and https, *BUT* at a cost that ssh and any other connections, at OS logging level, come from 10.0.0.1, which is innaceptable (i.e., I can' set proper security, regardless the F5 is badly configured), so I have to find another way for this. So, I thought of using iptables mangling capabilities, and my thought is that just changing the default route of the incoming http(s) traffic, everything should be ok. I've done the following:
If I tweak the hosts file in my M$ workstation to test individual access for each server, I can browse the websites with no problem, but if I set the service IP address, I get an error "Document contains no data" in the browser after just a few seconds. Apache logs show nothing in its logs. I can see packets arriving, but seem to go in a loop. I can provide some output, but since surely I'm making some mistake in the process, if I get help with the proper knoweledge about how to fix it, the problem will be solved. But if still someone needs it, I can provide more data.
from the router it split into 2 connection one to my GW (linux debian) and another to a switch which is connected to a web/email server and the gateway.
My gw use x.x.x.27 and x.x.x.26 (everything I use on these ips is ok)
on the web/email server I have x.x.x.28 29 and 30
With this setup it's ok but I want to eliminate the link to the switch and make it pass thru the GW and i can't manage to get it work!
I am sharing my DSL internet connection using a modem+wireless router (single device) to 5 systems. I want all my internet traffic to go through one of the linux boxes in my network.
The problem here is that wireless devices connect directly to the modem+wireless router.
Is such routing of traffic possible??
PS: I am not sure if i could convey my situation clearly...
I'm trying to work out how to route all traffic destined for the internet from all devices connected to eth0 to a wireless router access point via wlan0 on my Slackware box. I also have dhcpd providing ip addresses on the same subnet to any device connected to both eth0 and wlan0.
If I connect to the router/access point via wireless or directly to the Server via a crossover cable I can obtain an ip address from dhcpd, so that works. As far as I can see I just need to how to route between eth0 and wlan0 then I can provide internet access to those devices!
ifconfig:
Code:
eth0 Link encap:Ethernet HWaddr **:**:**:**:**:** inet addr:192.168.2.253 Bcast:192.168.2.255 Mask:255.255.255.0 inet6 addr: fe80::201:2eff:fe27:aea3/64 Scope:Link UP BROADCAST MULTICAST MTU:1500 Metric:1
I've been trying to setup an IPSec connection between two routers, but am having trouble with the actual packet routing.
My setup currently is two local networks (192.168.1.0/24[netLANA] and 192.168.0.0/24[netLANB]) that are connected to their own routers (192.168.1.1 and 192.168.0.1 respectively). The routers are both connected to the 194.26.1.0/24[netWAN] network. I wish to setup an IPSec connection between the two routers, to act in tunnel mode between the two local networks.
The first router is a linux box (on the netLANA network) that I am setting up using the ipsec-tools, and the other is a Netgear ProSafe FVS318G (on the netLANB). I've set them both up to have the same configuration for IPSec. Also, on the linux router I have setup a route like this:
Code: $ route add -net 192.168.1.0/24 wlan0
So that all traffic destined for the netLANB network will be routed to the wlan0 interface (netWAN in this case, and therefore over the tunnel).
My problem is that if I ping from any host on netLANA, I can see the ICMP reply comes back to the linux router, but it doesn't get back to the original host.
From the linux router, here is the tcpdump of the ping:
Code: $ tcpdump -n -S -i any 17:06:26.308353 IP 192.168.0.5 > 192.168.1.4: ICMP echo request, id 1036, seq 1, length 64 17:06:26.308780 IP 194.16.1.6 > 194.16.1.5: ESP(spi=0x0ea08914,seq=0x2f), length 116 17:06:26.316287 IP 194.16.1.5 > 194.16.1.6: ESP(spi=0x0be1036c,seq=0x2f), length 116 17:06:26.316287 IP 192.168.1.4 > 192.168.0.5: ICMP echo reply, id 1036, seq 1, length 64
I have a Pc that has 2 Ethernet and I have also 2 switch. I want the PC to become the router and be connected to 2 switch.How can I setup this one on FEDORA and I want to assigned for eth0 192.168.26.51 and eth1 192.168.22.51 for the IP.
I've setup an XP VM using Red Hat's KVM. The physical Red Hat box has two NICs, a fiber one in use and active and a CAT-5 one that is disabled and with no wire connected. The physical box has br0 active and bridging on the subnet of 192.168.10.0/24. ip route show also displays for virbr0 192.168.0.0/16 My physical box (192.168.10.228)can ping the virbr0 IP of 192.168.122.1, but not the XP VM of 192.168.122.228
I have played around with Window's route command to try and setup some method for the Windows VM to ping the 192.168.10.0 network, but have not had any luck. I've also messed around with the Red Hat netmask and such to work it from the Linux side. But then, as would be expected, I can't talk to other Linux boxes on the physical network.
Does anyone have any ideas how to get the Windows box to communicate with the Red Hat box and the other Linux systems beyond while keeping the two distinct networks of 192.168.10.0 and 192.168.122.0 leaving them both as Class C (255.255.255.0)? I mentioned the unused CAT-5 NIC thinking perhaps it could operate as an internal router even with no cable attached. That was just a random thought and I have not even explored that.
Im trying to configure a GRE over IPSec connection between two subnets. The IPSec tunnel is opened and now I want to add a GRE tunnel over it.So, what I didn't understand is why I can't route my subnet over the tunnel, once the only route I have there says that it should route the tunnel IP over the GRE01 interface. Any hint? Thanks.
