Networking :: Unable To Set Gateway When Second Network Adapter Fitted
Feb 12, 2010
When a second network adapter is fitted, the boot script fails to configure the default gateway. Here's from /var/log/messages with DEBUG_ETH_UP="yes" configured for the boot script Code: Feb 13 10:22:23 ps1 logger: /etc/rc.d/rc.inet1: /sbin/route add default gw 191.168.1.1 metric 1 Feb 13 10:22:23 ps1 logger: SIOCADDRT: No such process
After boot the same command failed with the same message when done by root logged in via ssh but succeeded when run from the console After removing the second network adapter, the boot script is able to configure the gateway.
EDIT: or not. The problem now seems intermittent Now with only the onboard network adapter the same "SIOCADDRT: No such process" error is logged during boot and the "/sbin/route add default gw 191.168.1.1" command fails at the console too. Am experimenting with disabling the onboard adapter and fitting the NIC.
EDIT 2: definitely intermittent. Just rebooted with no hardware changes; same error during boot and route -n showed no default gateway but "/sbin/route add default gw 191.168.1.1" worked.
I installed openSUSE on one of my work system. The network port wasn't working when I was installing, but works fine now (checked in Windows). But for some reason, I am not able to configure the network. I used both Dynamic and Static IPs (both work fine in Windows) but still no go. I am using Yast Control Center for this purpose. I can't even ping the default gateway when I am using custom settings. When I use dynamic settings, it says Unreachable Network.
Just received network adapter and unable to install. Belkin service was useless. Moved computer, running point to point on the LAN. Searching for a compatible driver and/or means of installation. Poor connection with Clear and modem's on top floor, Belkin's a good option.
I have two network card in my computer. 1. eth0 is set to automatic obtain IP from provider (DHCP) 2. wifi0 is set to static IP (local) 192.168.1.1
My ifcfg-wifi0 is configure in /etc/sysconfig/network-scripts/ifcfg-wifi0 as below # Atheros Communications, Inc. AR5212 802.11abg NIC DEVICE=wifi0 ONBOOT=yes BOOTPROTO=static IPADDR=192.168.1.1 NETMASK=255.255.255.0 HWADDR=00:17:9A:75:48:37
my /etc/sysconfig/network NETWORKING=yes HOSTNAME=pc1.homeserver.in
eth0 IP is connected to broadBand internet service provider device WiMax and IP change time to time from internet service provider. How can I get IP for gateway in /etc/sysconfig/network. I am using Redhat enterprise Linux 4.
I have a network gateway system which runs redhat 7 (2.2.16) Firewall running is ipchains Internal network is eth0 192.168.5.1 External network is eth1 99.99.99.98 (example add)
My problem when I change the static address of the external network from 99.99.99.99 to 99.99.99.98 I am not able to connect to internet. From my preliminary investigation ip is not binded to network card., but I am not sure, is there a way to check binding accurately Below is the ifcfg-eth1 file contents
I could not able to configure the default gateway ip address onto the system. i use the route command (" route add default gw 192.xxx.xxx.xxx eth0 ") to add a default gateway onto the routing table but it is "disappear" in the routing table when i had restart the service network.
My workstation is on a network, let's say 10.100.0.0/24. I'm opening up an openVPN Tunnel to a test environment in my company, receiving a lot of routes to this network (address range 172.xx.yy.0). Everything is working fine so far. In this test environment I placed a number of virtual systems having their own private network (10.99.0.0/24). I have one machine in this virtual cluster which is able to forward incoming IP traffic to the others.
When I login to this gateway system, using the 172.xx.yy.zz address, I can logon to the others using the 10.99.aa.bb addresses. Fine so far. But I have to be able to call these machines with the 10.99.0.0/24 addresses from my laptop. So I tried to add a route like: route add -net 10.99.0.0 netmask 255.255.255.0 gw 172.xx.yy.zz
Unfortunately I received an error messages: SIOCADDRT: No such process
According to the entries in other forum articles (Google helps in most cases), I have to add a host route first: route add -host 172.xx.yy.zz gw 172.well.defined.dest
7.2 Home Network Gateway. Has anyone used this gateway and will it support both desktop and laptop I ask this question because I use my desktop at home and when traveling the laptop. The desktop has Fedora and the laptop has cut my tounge out vista.
I've been struggeling with this for a few hours now, googleing and so on trying to find an easy way to just switch which device I want as primary for internet connections. After long battles I'm at a loss, this is the current automatic routing
Code: Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface 85.225.76.0 0.0.0.0 255.255.252.0 U 1 0 0 eth0 85.225.76.0 0.0.0.0 255.255.252.0 U 2 0 0 wlan0
I have a laptop running OpenSuSE 11.2. I use the Yast menu to set up network settings via "traditional" ifconfig setup (not NetworkManager), because I found NM unusable in prior releases when doing network gymnastics such as router re-flashing, LAN reconfiguration, etc. where I needed control of the IP address, netmask, DHCP, tftp, etc. My laptop works fine with Yast "traditional" ifconfig configuration for eth0 connected to router to Internet. Works fine with Yast ifconfig configuration for USB WiFi as wlan1 to WiFi router to Internet. Also works fine for virtual machines on vmnets NAT-ed to the Internet. Works fine as long as there is only one network connection, that is.
Now, I have a second laptop. I want to network laptop #2 eth0 to laptop #1 eth0 for file transfer and/or Internet access WHILE laptop #1 is is linked to the Internet through wlan1. Unfortunately, I have not figured out how to get Yast/Network Configuration to do that. I have not been able to get Yast/Network Configuration to see both wlan1 and eth0 at the same time--when the Yast utility finishes, I do >ifconfig and >route, and I find that I have lost either eth0 or wlan1. Thus, when I do direct-connect file transfers, I loose the WiFi Internet connection on both machines.
I suspect that it might have something to do with Yast/Network Configuration utility not being able to handle two network interfaces on the host with different IP addresses. how to properly put an OpenSuSE machine on two networks simultaneously? And then how to turn on IP forwarding so that I can use laptop #1's WiFi as an Internet gateway for laptop #2?
A node on a cluster that our lab has had sitting in a dusty room since time forgotten does not seem to want to talk to the rest of the world any more.Following is the information I found was being asked for on other posts for similar questions, transcribed by hand.
Im currently unable to install a wireless USB network adapter because it requires an installation which can only be done with a cd and im not sure how to install the software to run the wireless adapter.
I have just installed Ubuntu 10.10. It is great and all but I am not able to get my wireless adapter working...it is a cheapo one and I have found different tutorials around the internet trying to get it to work...to no avail!
i am using fedora (2.6.35.6-45.fc14.i686), i am not able to configure the usb based wireless adapter, its DWA 125(Dlink) uses ra chipset.

here is the output
Bus 001 Device 002: ID 07d1:3c0d D-Link System DWA-125 Wireless N 150 Adapter(rev.A1) [Ralink RT2870]
i have got the driver loaded with the help of modprobe, still unable able to make it right. when i use system-config-network - wireless - no sign of RT2870.
Basically a few weeks ago I decided to try Linux, in particular Ubuntu. I have it installed in my Windows 7 partition but now I am willing to take the full plunge and switch to it all the way. The only issue is I cannot connect to wireless internet. It states "device not ready". Wireless is turned on on my laptop, I am very near the source, have tried making a manual connection with the network setup. I tried the hardware tester and it found my ethernet and wireless hardware (Broadcom 802.11g Network Adapter). I went to the package thing and looked for Broadcam. I found a package but it was already installed. I tried it manually with:
sudo apt-get install bcmwl-modaliases E: Could not get lock /var/lib/dpkg/lock - open (11: Resource temporarily unavailable) E: Unable to lock the administration directory (/var/lib/dpkg/), is another process using it?
I then heard to try "sudo apt-get install bcm43xx-fwcutter" and did but it couldnt find it.As stated before I am new to linux so I'm probably missing something easy I just beg your patiance as I learn this new operating system.
I have a Belkin N150 USB Wireless Network Adapter and a Belkin N150 Wireless Router. I cannot seem to get NetworkManager to connect to the internet. I have blacklisted the 9.10 staging driver and associated rt files. I have downloaded and built the ralink 2.3.0.0 driver. The light flashes on the usb but I cannot connect to internet.

I am not sure what the ra0 is telling me but what about the Access Point: Not-Associated statement? Does that mean that the network adapter is not connecting to the router?
I'm trying Ubuntu for the first time; it's actually the first time I've messed with Linux at all-- and, well, it's kind of intimidating. One of my hobbies is playing with dead computers, and long story short, I have Ubuntu installed to a partition on an external drive connected to an older Dell desktop with no internal storage to call its own. The only network adapter I have to spare right now is the rather wimpy USB one that came with said desktop. I have the CD with the drivers to it, but I think the Linux drivers on it are for a different distribution. Am I going to need to scrounge up another network card or adapter, or am I going to have to start sheepishly asking ridiculous questions regarding basic operation of the command console?
I used Several Distos, went to school up to Linux 225, but haven't used Linux for years. I have an older (P4, Win xp) laptop I use at the coffee shop. I want to put Linux Mint on it. I use a USB Adapter (Arilink101 AWLL6075) for Wi-Fi. I tried the live CD and, of course, USB Adapter doesn't work. In the half hour I looked at it, I realized I forgot a lot of things. I could not even find the laptop USB. Will tring to get it to work be the typical Linux thing, where you download the drivers, do the install right, and it doesn't work? You compile drivers, set everything up right, and it doesn't work?
I'm unable to use Cisco Linksys Wireless-G USB adapter - Model No. WUSB54GC ver 3.

Tried startup with device connected, no success.
Read some threads which generally correspond to version 2 of the device.
It probably uses Ralink chipset(cmiiw). I neither have Rt73 nor prism2_usb installed, confirmed by lsmod.
I have a crappy cat5 cable that only works at 10BaseT settings on any nic. I have a gigabit nic which I configure using;Quote:ethtool -s eth2 speed 10 autoneg offProblem is that this setting doesn't stick after a reboot. How do I make the change permanent?
I've installed it and it looks great. my problem is that I cant connect to the net since I could not find the driver for my onboard network adapter. it is a Gigabyte GA 945 GCM S2L board. of coarse I searched their site but it says that Linux driver I have to achieve from 3rd party. the adapter's chipset is a Realtek RTL 8111C but I could not find the driver for it. the only one that I've found - doesn't work. I must point out that when I've searched driver for my Nvidia display adapter- I've found it on Nvidia's site and it works great.
I have an HP Pavilion dv5 1002nr laptop running Vista. I decided to install Ubuntu using the windows installer, which did install well, but I decided that it wasn't for me, and uninstalled it. Now, my wireless adapter which is a Atheros AR5007 802.11b/g can see the network, find networks by itself, and is supposedly installed correctly according to Vista, cannot connect to any networks at all despite being able to see them and acquire a signal strength. Up until installing Ubuntu I have never had an issue like this. Other devices have no trouble connecting to this network, and I am currently using a Netgear wireless usb dongle to connect to the very network that my Atheros can not connect to.
Is it possible to create virtual network adapter on the same physical network adapter? or How to give or have multiple MAC Address to the same adpater? I m working on centos 5.3.
On my desktop, I have Windows 7. I just also installed ubuntu on a partition in order to dual-boot. The installation worked fine, however now I cannot use the internet on either os. I have a Realtek PCIe GBE Family Controller On Windows 7, the LAN flashes from "Enabled" -> "Identifying" -> "Network cable unplugged". It does this on a seemingly continuous loop. When I disable it, it will not let me enable it. It says it can't start. Also, I uninstalled and re-installed the driver for my ethernet with no change.On Ubuntu, when I try to do "ifconfig eth0 up" and "dhclient eth0" I get the message "No DHCPOFFERS received. No working leases in persistent database - sleeping."
I can't post messages, I think something is wring with my internet.Anyway, I'm gonna copy paste what I've been trying to say...I just bought the TP-LINK Model No. TL-WN821N. It's an atheros. And I was wondering where can I find the drivers for Linux. It only includes drivers for Windows.
I don't have much experience with networks,I found this website,

I got stuck in the patch section, I don't know what they are trying to say. They are using
