I have just changed my gateway address,now I can access internet with my browser but unable to run add/remove software as it says no network connection available,system updates are not working as well. What should I do make these working?
when I do "route -n", I got:
Code:
Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
192.168.1.0 0.0.0.0 255.255.255.0 U 0 0 0 eth0
169.254.0.0 0.0.0.0 255.255.0.0 U 0 0 0 eth0
127.0.0.0 0.0.0.0 255.0.0.0 U 0 0 0 lo
0.0.0.0 192.168.1.1 0.0.0.0 UG 0 0 0 eth0
I need to change the static configuration, like I 169.254.0.0, I don't know how it got there also I want to delete 192.168.1.1 from a static gateway. How can I do this?
I have a requirement of switch between wireless network with a single wireless device. First it should be switched to adhoc mode and then after sometime switch to infrastructure mode to establish internet connection. Everything works fine except the gateway settings.
I have used:
system("route add default gw x.x.x.x dev wlan0") to set the gateway, where x.x.x.x is gatewayip address.
I have used this whenever switching happens in addition to ifconfig command to set the ip address and netmask. But this is not setting the gateway ip address. How to set gateway IP address?

Im trying to achieve the multiple uplinks/provider found on LARTC.org. I have to get the IP addresses from my interfaces (EF1 and EF2) by using a script, but i dont know where to look at for the default gateway from each interface which got their ip address from my ISP.

As you can see, I am directly connected to router 192.168.25.1, and so my ip address is 192.168.25.101. I want my ip address to be 192.168.13.101, and make router 192.168.13.1 my gateway router. Is this possible under the current physical layout (I do not want to have to connect directly into 192.168.13.1, but keep my computer where it is at)?
When I run tracepath, it shows 192.168.13.1 is one hop away.
What I've tried:
The problem is under this manual setup, I cannot ping 192.168.13.1 and running command netstat -rn returns the following:
Some people may need to change the mac address of their ethernet network cards. This can be easily done with fedora with command line. Just follow the steps below:
1. Log as root on a textual console (ctrl+F2) or through "su -" command in your console
2. Print your network configuration with ifconfig
[root@localhost ~]# ifconfig
eth0 Link encap:Ethernet HWaddr 00:23:8B:6A:7E:9E
inet addr:10.1.128.244 Bcast:10.1.255.255 Mask:255.255.0.0
inet6 addr: fe80::218:8bff:fedb:7e9e/64 Scope:Link
[code].....
Here, eth0 is the ethernet interface of your system. The mac address is put in red.
3. Change your mac address using the following syntax
ifconfig eth0 hw ether 00:18:8BA:7E:90
The new value (in green) must be hexadecimal
4. if you have a dhcp server that distributes the adresses automatically, then request a new adress for your eth0 interface
[root@localhost ~]# dhclient eth0
5. Now, your interface is up and have a new mac and IP addresses. This feature may be useful if the network administrator ban you according to the mac adress, for example .........

I've just reinstalled F14 with KDE rather than Gnome and I'm finding that I'm unable to assign a static IP address to my wired connection.
KDE automatically connects via DHCP, but when I go into KDE's network manager, the eth0 connection isn't listed. In fact, no wired connection is listed. If I manually add one with the correct settings (including a static IP), it switches back to DHCP upon rebooting.
How can I get around this? Should I install the networkmanager-gnome package?
I couldnt find something for changing mac address for wireless. how to do that....

and please check my sample IP configuration !!!
interface : eth1 (ISP IP)just for example
IP :192.168.0.2
gateway:192.168.0.1
dns:202.56.230.5
dns:202.56.230.6
Interface : eth0 (my local lan )
192.168.1.1
255.255.255.0
IP address of xp clients ranges form 192.168.1.2 to 192.168.1.16 with default 255.255.255.0
my question is that which gateway address and dns i have to give to my clients for accessing internet ?...
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

you know ,we can get a Iface's MAC Address,IP Address,NetMask by function ioctl(), But how Can I get a Iface's Gateway by ioctl or other funciton!
View 5 Replies View RelatedAs I try to change my if0 MAC address either from /etc/networking/interface, or from GUI application, when I try to reconnect (through GUI) the application automatically creates some sort of alias interface with the default MAC every time, and leaves the one with the changed MAC aside.

I purchased a Dell Notebook n4030, that came with the wireless adapter from Broadcom BCM4313. It's been a while since I've been battling with the Broadcom driver to make it work perfectly. I did it!
But some servers I work with wireless in my town and I need to always be changing the MAC Address of my wireless adapter. Whenever I make the change, which is in the Linux distribution is already using it, when I enter the command:

Then I give an UP interface, but after that the adapter does not get the IP address of the network.
I am coming across a strange error with my gateway. When I do a "ping", this is what I get below:

View 2 Replies View RelatedI have followed some instructions to change to a static ip address and have now lost my connection to my router. The mistake I made was not copying the original "interfaces" file before making changes.The file originally had: auto wlan0 iface wlan0 inet (something - I thought it was loopback but didn't work when I added it).
The instruction told me to put:
auto eth0
iface eth0 inet static
address 192.168.1.100
netmask 255.255.255.0
network 192.168.1.0
broadcast 192.168.1.255
gateway 192.168.1.1
Which I did, using my own ip numbers, except for "broadcast". I didn't add that in because I didn't have a clue what to put there. When it didn't work, I tried putting it back to what I originally had except I can't rememebr that last bit. I added dhcp instead of what I thought it was but this didn't work either.
Now I'm not too clued up about networking and IP addresses. However, I know that I have an IP address for my router (which is dynamic) and then all of my machines have internal address e.g.
192.168.0.2
192.168.0.3
etc...
My server, had the internal address of 192.168.0.4 but now has changed to 192.168.0.7 what causes this to happen? I have to change my port forwarding on my router to allow access to my server from outside my network.
My laptop has an internal Broadcom wireless adaptor. It works fine for basic Internet access, but I cannot change the MAC address with ifconfig. I would like to be able to change my MAC address. Since this is a laptop, the only option for me to do this is a USB wireless adaptor. But compatibility is very hit-or-miss. I've already tried two USB adaptors that had been stated to be compatible with Linux, and while both worked for basic functionality, neither allowed me to change the MAC address.
For whatever reason, this information seems very, very difficult to find. I have spent upwards of ten hours cumulatively searching forums (including this one) and other resources, and have found only vague, outdated, or outright false information regarding USB adaptors that support this. I believe I will be doing a great service to other users like myself by getting this question directly and conclusively answered for once, and the more responses, the better.
Questions:
Do you have (or know of) a USB wireless adaptor that actually allows you to change the MAC address?
If so, what is the specific brand and model number, and what steps were necessary to install the drivers?
Can't change from dhcp to static ip address.I've installed Oracle's version of Linux Redhat 5, but I'm having no success changing from dhcp to a static IP address. My machine is plugged directly into a Belkin router which has the IP address: 192.168.2.1.If I use the gui: /usr/bin/system-config-network and set the network device to dhcp,it works fine. But if I set the IP address manually, I get no internet traffic, and if I ping an internet website, "network unreachable".The installation instructions for Oracle say that they want a full domainname. I've tried gateway.2wire.net. This worked in the last place I did a successful installation.It was the address of my ATT router. If I plunked that into a browser, I got the router configuration.

View 6 Replies View Relatedchange my WLAN0 MAC address in my Kubuntu Natty 64 bit at every boot. I have done quite a bit of searching and found some procedures that appear to have worked back in 9.04 and before days but I have been unable to get anything to work for me in my 11.04 install. I have tried adding a script to if.pre-up.d and also tried adding a bootmisc.sh and either I did them wrong or they are not working. I want to make sure that every time I bring the wireless up in Kubuntu that I have the changed MAC address. I usually keep wireless disabled and turn it on just when I need it.
Background so you don't think I am doing something nefarious... I am going on a cruise soon. The cruise line sells wireless internet subscriptions for the duration of the cruise but they tie it to a MAC address. I am bringing my CDMA android phone that unless I use VOIP will be unable to call at all or at least with very high charges. But I also want to be able to browse the internet with my laptop. I figure it will be easier to spoof my phones MAC with the PC than the other way around. I just need to turn one device off if I am using the other. I need the MAC address to be semi permanent so I don't turn it on by mistake and have forgotten to change the MAC.
I have a script that will change my desktop image to display all of my network IP address. I need to call this script whenever a change in the network occurs. Example, if I disconnect from one network and then connect to another network and get a new IP address.
