Showing my ignorance, but why would this work
address 172.16.1.8
netmask 255.255.254.0
network 172.16.1.0
broadcast 172.16.2.255
[Code]....
Notice the 2 in address. Seems to me it doesn't like the network and wants it to be 172.16.0.0, but I am adding to a network already configured this way.
Someone just erased my HWADDR line from /etc/sysconfig/network-scripts/ifcfg-eth0. How can I obtain my original MAC address?
Code:
ifconfig eth0 does not work (it shows the wrong MAC address) since the HWADDR line from the file I mentioned above was erased. Also there is no ifcfg-eth0.bak backup configuration file.
Just curious, because it seems my wireless connection works regardless of whether or not the MAC address is listed there. I'm just curious why that option is there to add it if it works regardless.

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.

View 3 Replies View RelatedI recently just upgraded from humble Linux user to confused Linux admin of my own virtual Linux server. When I issue the ifconfig command I get following output.
Code:
venet0:0 Link encap:UNSPEC HWaddr 00-00-00-00-00-00-00-00-00-00-00-00-00-00-00-00

UP BROADCAST POINTOPOINT RUNNING NOARP MTU:1500 Metric:1
The WAN IP of the interface is not really 1.2.3.4 I just changed that IP for security reasons.What I am trying to figure out, is it possible to assign a private IP address to the same interface or can I only have one IP address per interface. I understand I have a mask of /32 so I am not going to be able to subnet the address to create any more addresses, so I assume I am stuck with the WAN IP (public IP) that I have, and just need to deal with it.
The reason I ask this is because I have been reading through several DNS/BIND tutorials/walk-throughs, and a lot of them specify setting up a intranet access with 192.168.1.1 address for the local DNS server, but since I am connecting to the sever via SSH I figure I do not need a private IP address.
Version 10.04 LTS. Installed desktop version and network worked but I needed a static IP address and the install configures for a DHCP configured address. I tried changing to static address using the System->Preferences->Network Connections application but was unable to get the system to come up with the network up.
So I manually modified the /etc/network/interfaces and the /etc/resolv.conf files. I restart the system but when I do an ifconfig, I don't see a configured IP address on eth0 (only the loopback address). If I run /sbin/ifup eth0 everything then works fine and ifconfig shows the correct address bound to eth0.
My files are as follows:
how to do a virtual interface under linux. I'm using for example eth0:1 so ifconfig eth0:1 192.168.0.20 netmask 255.255.255.0 for example.
However if i do eth0:1 hw ether 00:11:22:33:44:55 It changes eth0 as well. Where should i look into for creating a separate virtual interface that's simply bridged with one of the existing interfaces that has a separate ip and hw address that the os handles.
I have two network interfaces in my pc eth0 and wlan0 and a virtual one br0.
router <= eth0 (0.0.0.0) => br0 (192.168.1.10) <= wlan0 (0.0.0.0) => other pc.
On startup of my pc (ubuntu 10.04 server x64), samba bind itself only to loopback network interface, as i can see when i do netstat -an , preventing me to enter in my shares from a remote pc.
Here is my configuration regarding samba network:
Code:
interfaces = 127.0.0.0/8 192.168.1.0/24
bind interfaces only = yes
and my /etc/network/interface
Code:
# The loopback network interface
auto lo
iface lo inet loopback
code....
Any idea fo speed up my bridge configuration or to force samba to wait unitl the bridge is ready?
my wireless home network is not recognized by my network card (RealTek RTL8190 mini PCI). The post was as follows: "I am using a new computer with Windows 7 , Athlon quad core 2.60 64 bit, 8GB RAM. Internet conection works fine with ethernet but ubuntu does not see my wireless network. card (RealTek RTL 8190 ID: 10ec:8190). Have searched this forum but unable to come up with a fix. I was looking for windows XP drivers to use Ndiswrapper but could not find a list of .inf files. My network is OK and works perfectly in windows and with my 2 laptops. Can anyone point me in the right direction? Additional info: install was done within Windows using WUBI to a separate partition on my HDD. I am new to this and thouroughly confused as to the procedure for installing the drivers if they are in fact available."
I am very frustrated in that I would like to use Ubuntu 10.04 but it is useless without internet connectability. I am new to linux and do not understand where to get the appropriate drivers or how to install them. I wish someone would answer this post and either give me a clue what to do or just say "give up" and uninstall ubunutu.
I am totally new to Linux and have just installed ubuntu 10.10. After configuring the network interface via dhcp I started getting these messages that come in so frequently I can't configure anything else.
[87.186415] Stack:
Why I am getting this messages and more importantly how do I get rid of them.
The installation is on a VM on Hyper-V.
today 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?
I have a desktop and a laptop connected by ssh (Places>Connect to Server). This works OK for file sharing but the laptop does not recognize the 2 printers attached to the desktop machine. As I understand (??) it, if the 2 printers are set up as 'shared' in CUPS (as they are on the desktop) then they should be recognized by the other machine on the network. But this is not happening. Is this the right way to network printers?

When I create virtual ethernet interface and do a ping -I <v_int> <host> the outgoing address is the one of the physical interface and NOT the virtual interface.Is there no chance that trafic will go out with virtual interface address??Incoming trafic is done well i.e. responds to the virtual interface have the virtual address.
My problem is that I have 2 modems and want to check both default gw behind the modems.
If I do a "normal" ping both are reachable over default route even the modem which is not the default route will not work because ping goes over the working modem.So I have 2 routing tables and want to route the virtual interface to one modem the other to the other modem
I'm having all sorts of problems connecting an access point to my computer, but here is one piece that I hope will get me going, if I can get it solved.My computer has two network interfaces, eth0 and eth1. eth1 connects to the cable modem and thence the world, and works fine. eth0 is supposed to connect to the access point over a private network. Here is the output from route with my IP address blotted out:

How can I force a Wine application (or Wine itself) to use a specific network interface? I have installed hamachi and am trying to play starcraft over virtual LAN. However, when I run Starcraft with hamachi running, it does not work. I have now determined that hamachi creates a network interface called "ham0". How do I force Wine/Starcraft to use the "ham0" network connection? I have looked into forcebindip but it crashes on wine.
