OpenSUSE Network :: Ifconfig With 2 Addresses On JeOS?
Sep 13, 2011
I have created my own distribution with susestudio.com , based on jeOS template and it works well But I have some problems with network configuration. I make a default configuration with susestudio ( configuration -> General -> network ) and I put for example 172.16.0.185 address. I also put a script which configures IP address with different informations coming from for example a serial port to make my own IP address. This script make the new address and call the ifconfig system program. For example, the script calls "ifconfig eth0 172.16.0.182". And now, I can ping the two addresses, 172.16.0.185 and 172.16.0.182. Is this normal ? I thought the new command "ifconfig eth0 172.16.0.182" would overwrite the old value ( 172.16.0.185 ). It works as this on other distribs ( like ubuntu ) but not on opensuse.
I know that I can have 2 addresses but using the following syntax : "ifconfig eth0:1 A.B.C.D" (if kernel supports aliases ) , and I don't know if it is normally possible to have 2 address from the same subnet. How can I overwrite the default config , and not to have the first address available ?

I'm on Fedora core 14 linux. and I'm online with the HSPDA modem. My modem is /dev/ttyUSB0 and when it's dialed it creates the interface /dev/ppp0 , My question is when I hit ifcofig it shows two IP addresses in the ppp0 interface.
Code:
[nature@localhost ~]$ ifconfig
eth0 Link encap:Ethernet HWaddr 20:6A:8A:12:CF:53
UP BROADCAST MULTICAST MTU:1500 Metric:1
RX packets:0 errors:0 dropped:0 overruns:0 frame:0
[code]....
when I get the routing table, the gateway is setten to the 10.64.64.64 and when I look my Ip address global I found it's 175.157.64.119.

I cannot seem to create a tun device using ifconfig, even though the module is loaded, and the node tun is present in /dev/net and appears to have correct access permissions, trying to use nstx which requires the tun device. Only thing I can think of is adding an alias, but not sure where, since there is no /etc/modprobe.conf or /etc/modules.conf in SUSE 11.3.

I am using Suse 10 sp2. By running ifconfig I am changing the mac address. Everything is happening successfully, but this is adapter losing the network connection. Even when I give a static IP. I am not able to ping any other IP.

I have been noticing a trend on boxes running 11.4 getting RX dropped packets where prior to 11.4 they did not get them. Basically every box running 11.4 now logs dropped RX packets. Have tried changing cables, and in one case replaced the NIC with a different brand (and driver) nic. Also played with receive buffers and yet the counters still increment. In addition to OpenSUSE, I run several operating systems to include Centos, Scientific Linux, Debian, OpenIndiana, HP-UX, VMS and so forth. So far this anomaly has only shown up on machines running OpenSUSE 11.4. Any one else noticing this on your OS 11.4 machines? If so, were you able to resolve?

The computer and system in question is the laptop from my description and openSUSE 11.3 with a different kernel from this repository :[URL]..free to move this thread if it should reside in the beta/prerelease forums section. The IMHO relevant information about my hardware and system is shown below.
The kernel I'm using :
Code:
grzes@opensuse:~> Linux opensuse.local 2.6.37.2-1-desktop #1 SMP PREEMPT 2011-02-25 19:59:41 +0100 i686 i686 i386 GNU/Linux
The hardware and drivers I'm using :
Code:
02:00.0 Network controller [0280]: Atheros Communications Inc. AR9285 Wireless Network Adapter (PCI-Express) [168c:002b] (rev 01)

I have a laptop running 11.2 with an internal Broadcom-based Wi-Fi card that's working fine. I'm trying to get 802.11n going with the WUSB600N. The USB ID on this device is 1737:0079. I believe this means it's a "V2" with an RT3572 chip.
No driver loads for this device when it's plugged in. If I do a "modprobe rt2870sta", a driver loads, and syslog shows "rtusb init" and "usbcore: registered new interface driver rt2870". But ifconfig -a doesn't show a new network interface. I've also tried building the RT3572 driver from the manufacturer's web site. It builds fine, and modprobe will load it, but I get the same results as the rt2870sta driver.

I want to set multiple IP addresses onto my server and I can then put under an alias.
But is it possible to somehow create a script in perl example that can do this for or is it only possible manually?

How do I assign IPv4 and IPv6 static addresses permanently in OpenSUSE 11.2? Currently I am only able to assign either IPv4 or IPv6 static address not both. I cannot find even the interfaces file(/etc/sysconfig/network/interfaces).

The default installation of 11.3 has ipv6 enabled.When accessing a site using any browser, there was a considerable delay before the page would appear.I disabled ipv6 and things are normal.Is my computer going to explode in a couple of months from all the backed up addresses? Seriously, Is there something wrong with my setup?Why would ip6 be enabled by default if it slows things way down?There are just so many things I don't know.

In SuSE firewall0. I do have a openSuse 11.4 and multiple IP addresses on eth0 interface
I run (trying to/have to) multiple TOMCAT servers.
I am trying to have each tomcat instance listen to on separate IP address for example:
What i am trying to do is to redirect
a) tomcat 1 -
a) tomcat 2 -
And so on.
I know that it has to be possible.
I do have just eth0/
Is is it possible. Do I have to create "vittual interfaces"? eth0:1, .......... and do redirection ?
"Server" has got just single interface - just 1 ethernet calbe goes to that server. I am planning to have 10-15 tomcat's on that server (I have to unfortunatley) and each has to run on port 80
Is it possible to "grant" permissions to normal users to run app on port 80 - that would solve me lots of problems if impossible to redirect.
I tried to setcap 'cap_net_bind_service=+ep' /path/to/tomcat ...... but no luck

I have a problem with the network. Worth two network cards and Ian wan. Do not take the ip. When the system boots not included until you do the command ifconfig eth0 up. The network card is connected to a router, he does not see it. Router working, tested. Network card is working well, tested on Windows. RX RT packages go, withheld support for ipv6 and packages no longer go.

I messed up my Network Connections when I put a different NIC in my computer. Now I just went back to using the old NIC. It shows up in ifconfig, but the GUI Network Connections is blank. When I manually Add the connection back to the GUI Network Connections, the settings are not reflected when doing ifconfig.For example, I change the IP address for eth0 in GUI Network Connections, save the settings,

I have got Ubuntu 10.10 on a Dell Inspiron Laptop. Can't get anywhere with wireless network. Tried a few bits of poking it blindly with a stick:
matthew@ubuntu:~$ lshw -C network
Warning: you should run this program as super-user.
*-network

I reckon *-network DISABLED is a problem, I tried sudo ifconfig wlan0 up but that didn't work. The output of that and lspci are on the ubuntu side of my machine. I have also tried pressing my wireless on/off key (F2) but that doesn't work either.

I like the Jeos 8.04 small footprint but I need a different kernel and adding some extra packages. Id like to know if there's a way to repack the Jeos 8.04 iso with the new stuff. I want to have all in one iso avoiding the post installation kernel replacement and package installation.

I recently installed fedora 12 in my server where I had a page published in my local net by tomcat, and I was looking on the Internet how to set up an static ip address and this is what I did
on /etc/sysconfig/network-scripts/ifcfg-eth0
# Broadcom Corporation NetXtreme BCM5751 Gigabit Ethernet PCI Express
#
# File: ifcfg-eth0
[code]....
then I can access via ssh by two addresses the one I got from dhcp (10.17.148.223) and the static one (10.17.148.26) I put ifconfig and and 10.17.148.223 appear on eth0 I restart my server and I just can access from 10.17.148.223 I have to put
ifdown eth0
ifup eth0
Again...to access by my static ip, y can access my page by its dns on my server, but I cant access from other computer...so, I guess when my static adress appears on ifconfig I would be able to access my page from other computer...

how to get tab completion working with sudo in JeOS (Ubuntu Hardy) 8.04? Assuming I have the command '/usr/bin/svnadmin'. As a normal user I can type:
Code:
svnad + TAB
and it auto-completes as 'svnadmin'. If I type:
Code:
sudo svnad + TAB
nothing happens. My 'echo $SHELL' is '/bin/bash'. I tried enabling the following in '/etc/bash.bashrc':
Code:
if [ -f /etc/bash_completion ]; then
[Code]...
auto-completes as I'd expect. I think I once read that there's some kind of configuration variable for sudo that causes it to use a 'more secure' path rather than the current path in the user's environment. I can't find any info on it though. I'm executing the commands from my home directory.

i 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.

i know this is crazy, but im using a [URL] and have loaded a copy of "red hat linux 7" on the computer. i have no idea what kind of hardware config/spec stuff i should have in my immediate vision, and if i did i'm not sure how i would make sense of it all. linux loaded fine. didnt save drivers. eth0 not showing in ifconfig report, but lo is connecting to network, other host cannot ping linux and vice versus
can mount a cdrom, but not a usb flash dont quite understand how the load methods work involving /mnt/cdrom/"usbutils-0.86tar.gz" eth0 problems and gnome rpm stupidity keeps me from upgrading sys from old version to a newer version, cant even find the cmd to show me that info, sorry. have usb files i want to mount, dont know how to loAD THE CDROM FOLES, SO EVEN THAT ISNT WORKING OUT HAVE DISCS WITH howtos just need to stay focused on steps to get desired end result, while trying to learn too much info for what im currently doing between all the f!@#@ing windows i have open.

I am using DHCP on my home network. There could be as many as 5 computers logged in at any given time. Their IP addresses change depending on the sequence they log in.I want to be able to connect to them from any of them (some wired, some wireless) and share files by issuing a mount command for the appropriate shared drive.My question is how to get the IP of each computer when I only know the names of the computers. Pinging the computer name succeeds, but it does not give the IP.In other words I am looking for a Linux command that will come back with a list of IP's with their corresponding computer names so I can issue the right mount command. I would like to issue this command from a Linux terminal, but would also be happy to issue it from a Windows XP station.

I have four PC's in a home network setup, no server just peer to peer using ssh. I have tended to use wicd to set static IP addresses because Network Manager didn't always perform as I thought it should. Now that I have installed 10.04 I cannot see how to set static addresses using Network Manager so I installed wicd, and disabled Network Manager. After setting the address with wicd it shows that the computer is connected to the internet however I cannot get internet access, though I can network with my other computers. I've uninstalled and reinstalled a few times just to check that I haven't been careless but the results are still the same.

I've got two NICs connected to two different routers, and on different subnets of course. Each is set for static IP. But somehow I must have mixed up the connections at some point, so the NICs don't always have the IP addresses I expect. I think there may also be a mixup with different ways of setting the network addresses. When I click the Network Icon on the Desktop, I see that each NIC has both addresses as options. The /etc/network/interfaces file has some information about eth0, but all commented out, so there must be another place the addresses get set. And I just discovered that eth0 and eth1 aren't physical but virtual. I guess eth0 is the first one that is set.

I'm in the process of setting up a script in perl to make 1,000's of curl calls to my companies application on our test server. Our software does all sorts of tracking of data based on IP addresses using geoIP, so i was wondering if anyone knew of a way to fake these addresses to the server?I know a big issue with the IP faking is the return path but i dont really need this. I also cant do it on the hardware level since the script is going to be picking lots of different IP's at random.Anyone have any idea if this is possible and if so, are there any known libraries i can use for this? I prefer perl but any Linux compatiblie scripting language is fine.
