View 2 Replies View RelatedHardware :: New Network Card Not Mapping To Ethernet Interface?
Feb 21, 2011I've added a 2nd ethernet network card into my linux box. After I installed it the box recognized the new card and mapped it to eth1, as I expect. I then configured the addresses and routing for my eth0 and eth1 interface. Since then I had shutdown my box.When I next started my linux box up only eth0 was present.`ifconfig -a` only displays eth0, but `lspci` lists both cards. How can i permanently map the new pci card to eth1?
Code:
scattaneo@unthread:~$ ifconfig -a
eth0 Link encap:Ethernet HWaddr 00:1a:a0:8c:61:49
inet addr:192.168.2.108 Bcast:192.168.2.255 Mask:255.255.255.0

Security :: Mount 2 Network Interface Card (NIC) And Make A Bridge
Apr 1, 2010Actually i'm doing an ingenior training in SAGEM company, well i'm trying to develop an application which is able ti disturb the IP Network,my idea was is to mount 2 Network Interface Card (NIC) and make a bridge to pass the IP flow and to exploit the firewall Netfilter using iptables command.The application has to import a text file containing a binary array like this one:
0 1 0 : 0 corresponds to iptables -p ip ACCEPT
1 1 1 : 1 corresponds to iptables -p ip DROP
0 0 1
==> So the expected result is to have 5 ip datagrams dropped
My idea was: if 0 --> iptables -A FORWARD -p ip -m limit --limit-burst 1 -j ACCEPT
if 1 --> iptables -A FORWARD -p ip -m limit --limit-burst 1 -j DROP
The problem was: After executing the application and parsing the text file,
with iptables -L -v: i have
Code:
-A FORWARD -p ip -m limit --limit-burst 1 -j ACCEPT
-A FORWARD -p ip -m limit --limit-burst 1 -j DROP
-A FORWARD -p ip -m limit --limit-burst 1 -j ACCEPT
which is logic, but when i sniff with wireshark i find more packets are dropped(6,7 or 8 are dropped), like i had put more DROP rules. and sometimes i found the exact value(usually 5 dropped).
Fedora Installation :: "Error Configuring Network Interface" Halts F13 Upgrade With Atheros Card
Jun 6, 2010After an online upgrade from f11 to f13, on rebooting the setup attempts to configure the wireless connection and fails with a not very illuminating "error configuring your network interface" notice, offering no option but to go back and try again, which of course fails again with the same error.
Wireless card is a D-link that works fine with the ath5k driver in f11.
how I can get out of this vicious cycle and proceed with booting the upgrade?
General :: Assign Port Numbers Against Interface (LAN Card)
Apr 22, 2010I am using RHEL 5. In my Linux Box I have two Lan cards (eth0 and eth1). "eth0" is connected with network 192.168.10.0 and "eth1" is connected with network 192.168.11.0. Both Network are inter connected via routing. Now I want a situation where, I want to dedicatedly assign some port numbers against a lan card. Like eth0 will be assigned for ssh (22) and eth1 is assigned for telnet (23). So that, when a user connect to 22 port then he/she is connected to the server through eth0 , and when a user connect 23 port then he/she is connected to the server through eth1. Is it possible to do using iptables or other?

View 2 Replies View RelatedNetworking :: Displaying Network Usage Stats
Jul 13, 2010A small "mom and pop" WISP would like to provide account usage information to customers.Basically, when a person connecting to the WISP's web site is a customer with an IP address from within the WISP's subnets, a link would appear on the web page where customers could read total bandwidth usage (daily, weekly, monthly, and yearly totals and averages) and public IP address. Information could include the top five bandwidth URLs visited; graphs or charts of usage; and usage during specific periods, such as business hours (8AM-5PM), evening hours (5PM-10PM), night (10PM-8AM), and weekends (10PM Friday-8AM Monday).
The WISP has installed cricket (http://cricket.sourceforge.net) and rrdtool (http://oss.oetiker.ch/rrdtool). The next trick is to grab and format the data for customers.I'm not looking for answers like "look at xyz package." Helpful responses will include a rudimentary outline to solve the problem. That is, "xyz package" might indeed be what the WISP needs, but some guidance how to use xyz is needed to move down the road.I have no experience with this type of thing. I appreciate responses from people who are experienced.

Networking :: Configure A Network Route To A Host For Testing Network Interface?
Aug 30, 2010today I tried to configure a network route to a host for testing my network interface. Code: route add 192.168.1.15 eth0 As I have to eth interfaces and both interface got their IP from DHCP (192.168.1.11 and 192.168.1.12) and are in the same subnet, I shut the other interface down:
Code: ifconfig eth1 down Then I tried to test the interface by doing a ping to 192.168.1.15.
Problem: When I unplug the cable from eth0 (and eth1 is still plugged) the ping still works. Somehow my linux (it's debian) powers up again eth0 and pings over this port.
How can I stop my linux doing this. I just want to have the route added only on the one interface - not the other. Is it maybe some case of a default-gateway?

Networking :: Cannot Ping Virtual Interface On WAN Card
Feb 1, 2010I have an ubuntu server that I am using as a gateway router. I have 2 nics in the machine and am using iptables to run the NAT.I now have a need to provide several machines on the inside of the network with their own public IP. So I created a virtual interface on the the WAN card and attempted a 1:1 nat across it, but it's not working. The virtual interface isn't even responding to pings. If I ping the ip of the virtual interface from the outside, it doesn't work. If I run a tcpdump on the interface, I can see ICMP request packets but no replies. Watching the same dump while pinging the non-virtual interface IP results in both request and reply packets. What's stranger the inbound ICMP request packets on the virtual interface seem to be hit or miss. Sometimes when I ping it, I can see the request packets hitting the interface, sometimes I get nothing.

Aug 14, 2011i recently started sockets programming. In the process i began to look for relevant network information about my computer and realized that ifconfig wasn't displaying the same information that resides in my /etc/network/interfaces file. On the interfaces file my IP address is 192.168.1.109 for interface eth0 but ifconfig displays 192.168.1.101. I was under the impression that ifconfig got its information from the interfaces file but clearly doesn't. I tried re configuring the device with ifconfig and then disabling and re enabling the device with ifdown and ifup so that the device updated its information but it didn't.

Ubuntu :: Wireless Card Won't Stay Connected - Iwconfig Says Wlan0 Is Interface
Jun 11, 2010having trouble with my asus 1000 rt2860 wireless n card and WPA/PSK/WPA2 connections. Funky thing is it worked in the 2.26.32-21 kernel (iwconfig shows ra0 as the wireless interface), but when the kernel was updated and pushed through in the ubuntu updates to 2.26.32-22 the wireless card won't stay connected and iwconfig says wlan0 is the interface. I checked the proprietary drivers and they said that the driver for my card was active, but not in use. How do I use the ra0 instead of wlan0?
how do i use the driver that's listed as not being used? I'm having to boot up lucid with the older kernel now, it's annoying, lots of programs aren't running as expected as a result. I've tried manually installing the driver from the RaLink website as detailed in many other posts concerning this wireless card. It seems to work for some people, but not with me.
