Debian Configuration :: Ifconfig Wasn't Displaying The Same Information That Resides In /etc/network/interfaces File

Aug 14, 2011

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.

Debian Configuration :: /sbin/ifconfig: No Such File Or Directory

Aug 2, 2010

I am using Debian Lenny as my server to host multiple databases.

Whenever, I used to add a new database, I used to add an IP address like eth0:test in the /etc/network/interfaces file.

Today when I tried to do the same, I got an error when I tried to start the interface by typing "#ifup eth0:test". I also tried to do in this way "#ifconfig eth0:test up" but both of then yielded the same error saying "/sbin/ifconfig: no such file or directory".

The path is valid and the files are also present there. There are ifup, ifdown, if and ifconfig files in the /sbin directory. I also checked the permissions which is root:root. But still I cannot find the problem.

Debian Configuration :: /etc/network/interfaces: Ra0 Or Wlan0?

Mar 30, 2010

I had one of those random system deaths, so reinstalled squeeze (daily netinst image I think...) on my eee 1000, which uses an rt2860 wireless chip. The new install only installed 2.6.32, which I had been avoiding using because of a few problems, including it dealing with networking slightly differently. I couldn't get it to work - even without encryption - using wicd. Having had a read of [URL]... , I had a look at /etc/network/interfaces, which read; This file describes the network interfaces available on your system and how to activate them. For more information, see interfaces(5).

[code]...

ra0 is now called wlan0, as far as I'm aware. I've read in several places that it is best to expunge this file of all references to wifi, so I removed the bottom section (after '# The primary network interface'). I still got nothing. However, if I go ahead and change the 'ra0's to 'wlan0's, it seems to work - wicd connects. Not very familiar with Debian (spent more time on SUSE. Drop your tomatoes - I like it. Any idea what is happening? Is what I'm doing wrong? Conversely, is the file wrong? Should it be reported? Against which package? Including any particular files?

Debian Configuration :: Multiple Network Interfaces With VirtualBox?

Mar 29, 2010

I have a rather urgent problem with my network, I got two virtual network interfaces one internal and one external. The problem is; I can't get connection to internet. The external NIC is set as a NAT and the internal is... internal.

/etc/network/interfaces
auto eth1
iface eth1 inet static
address 192.168.1.200
netmask 255.255.255.0

Running with this configuration makes my internet connect go away, however if I remove the configuration for eth1 everything is working fine.

Debian Configuration :: Network / Interfaces Allow-hotplug And Auto?

Jan 10, 2011

Networking :: Make A Network Interfaces Configuration Immutable?

Mar 24, 2011

Similar to the linux command "chattr +i filename", I would sure like to set my eth0 interface immutable. so once I assign the eth0 interface's IP and gateway, make it stay set until I say otherwise.

this way, I can run dhclient or Networkmanager on another interface without having to fret that it may alter this interface. is there something out there that can do this?

Debian Configuration :: Atheros Ar542x Hard Blocked After Ifconfig Down And Up

Aug 20, 2015

I am having some troubles with my networking. I have a fresh install of Debian 4.0.4-1. My problem is: I boot up and everything is great.

Code: Select all~# ifconfig
eth0      Link encap:Ethernet  HWaddr 00:1e:68:46:4b:ae 
         
     UP BROADCAST MULTICAST  MTU:1500  Metric:1
     RX packets:0 errors:0 dropped:0 overruns:0 frame:0
        TX packets:0 errors:0 dropped:0 overruns:0 carrier:0
         
[Code] ...

I try to switch the hardware switch on and off with no avail. The only way to fix it is to reboot. But then when I ifconfig down and up I'm stuck in airplane mode again.

Debian Configuration :: How To Modify Traffic Between Two Interfaces In Linux

Aug 8, 2015

I have a laptop connected to internet via wlan0. I also have eth0 interface and with it I share internet. I want to modify/filter all the traffic passing by the first laptop, something like this:

Code: Select all                    *---------------------------*
                    |        LAPTOP 1           |      *--------------* ?
                    |-----*    *------*    *----*      |              |
    INTERNET<------>|wlan0|<-->|MY_APP|<-->|eth0|<---->|ANOTHER LAPTOP|
                    |-----*    *------*    *----|      |              |
                    *---------------------------*      *--------------*

I know that in FreeBSD it is possible to use ipfw for that purpose, because it build-in into kernel. We set for example rule Code: Select allipfw add divert 2000 ip from any to 1.0.1.1

and we can use our own application to process those packets, reinject them forward etc. It will work also fast, because as I said, it build into kernel.

Is there any standart Linux-based solution to do the same? I found some info about netmap-ipfw. Is this a correct solution? Or I have to use for example IP-aliases and iptables to do that?

I need to process all the IP-packets, not only TCP/UDP/etc-protocol. Solution also must be very fast.

Debian Configuration :: Bringing Up Wireless Interfaces At Boot Also

May 11, 2010

My new Squeeze machine detects all of my hardware including the LAN and WLAN cards, but only brings up the LAN card. There isn't even an entry for it in /etc/network/interfaces for me to modify. I tried adding the info manually but then the entire network wouldn't start. I had it configured as a static IP and I know the commands were correct due to them working on the LAN card. I believe that the name "wlan0" was causing the problem, but how else can I bring it up at boot?

OpenSUSE :: 11.4 KDE - Information Displaying On Screen

Jul 22, 2011

I am new to linux go easy please. I have about 200 machines with opensuse11.4 KDE on them, I would like certain information to stick to the background kinda like a widget type of thing that cannot be removed by a user (no admin rights) and it has to start on machine boot up and also these pcs are continually moving to different spots in our building but on the same network so idk if that changes anything with configuring the ip address.... the only things that need to be visible are as follows:

Host name
User name
IP address
domain

So basically widgets are useless to me, unless somebody knows how to configure these the way I need them or maybe there is something better then widgets. I came here to get the right answer from all you geniuses out there instead of trying to hop around on google and whatnot. Let me know what my options are and how I can roll this out on 200 PC efficiently.

Ubuntu Networking :: Set The IP In The /etc/network/interfaces File And Reboot?

Jan 20, 2010

DSL modem is a Speedstream 6520 router. All computers work fine via dhcp. I'm trying to setup a small server (print server, ssh & ftp servers). I understand enough of the software part of things to get it going, my problem is setting a static IP on the server box. Every time I set the IP in the /etc/network/interfaces file and reboot, I have no network connection. I can talk to the modem through the browser, but nothing beyond that, not even local computers.

/etc/network/interfaces
auto lo
iface lo inet loopback
auto eth0
iface eth0 inet static
address 192.168.254.202
network 192.168.254.0
netmask 255.255.255.0
gateway 192.168.254.254

ifconfig shows the .202 address, but box can't get to the outside world, and can't ssh into the box from a computer sitting next to it. If I let it dhcp, then I can ssh into it, and have access to the internet. In the modem, I have dmz set for that address. Wan address is static. I can ssh into it if I let it do dhcp, so I know it can work that far. But if I set static ip, I might as well pull the network cable. I've been beating my head on this for over a week, and I'm lost why I can't get it to work. I even changed the dhcp range on the modem, so the .202 is not in that range. There is no dhcp client installed that I can find. I'm using WattOS beta3, which is a light distro based on 9.04. The computer is an old Dell GX150, integrated nic. I have done ifdown and ifup eth0, still no happiness. Doesn't seem like it should be that hard, but I'm stumped. DMZ should let everything pass, so don't need to mess with port forwarding and such. I know it works using dhcp.

Debian :: Still Can't Reload Network Interfaces?

Mar 24, 2011

So I've always asked this in the past when I get on a Debian system. This makes no sense to me but I just don't see how I restart network interfaces (i.e. eth0) on a standard Debian install. If I change the static I.P. address listed in /etc/network/interfaces from x.x.x.100 to x.x.x.101, I then assume I can simply do any of the following:

- /etc/init.d/networking stop | start
- ifdown eth0
- ifup eth0
- service networking stop
- service networking start

All the commands above do nothing. My only solution I know that works and implements the changes I've made is a complete system reboot which to me in Linux, is ridiculous. I've struggled with this over and over and nothing I do correctly assigns the new I.P. in the 'interfaces' file to the actual adapter. This isn't my single isolated Debian machine but every Debian machine I can get my hands on. Servers, workstations, VM's, any release, etc etc etc. Below is my interfaces configuration file:

Code:
auto lo
iface lo inet loopback
