Alright, every time I boot or shutdown my routing box, it hangs at configuring and deconfiguring network interfaces. Below is my interfaces file. I see no errors or warnings in my log and I am running a pure kernel, not tainted with proprietary drivers. All of my hardware is 100% supported.
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?
I have a netgear wg111t that is running with ndiswrapper. It has an atheros chipset, but calling it ath0 didn't work.
Heres /etc/network/interface :
# This file describes the network interfaces available on your system # and how to activate them. For more information, see interfaces(5). # The loopback network interface auto lo
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.
I was just wondering if there's any point having both auto and allow-hotplug against the same interface in network/interfaces as allow-hotplug seems to bring an interface up at boot on its own.
I have a Dell PowerEdge SC430, Squeeze 6.0.2 box, Broadcom NetXtreme NIC which works fine DHCP. The network-manager package is not installed. I have now reconfigured /etc/network/interfaces for a static IP:
auto eth0 iface eth0 inet static address 192.168.1.2
What is the maximum number of virtual network interfaces possible?I would like to create around 300 or so. This is needed to simulate a 300 node network.
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?
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've been following this guide for squeeze: [URL] After getting the wireless-tools and firmware-ralink packages installed with no internet, I managed to installthe driver using modprobe rt2870sta (the 4th step). With the module loaded and the device plugged in (a RangePlusWireless Network USB Adapter with the WUSB100v2 chipset), iwconfig returned something like
[code]....
and then ifconfig wlan0 up returned ERROR while getting interface flags: no available device
I have two physical NICs (eth2 & eth3) with eth2 connecting to the home router/dhcp server and eth3 connecting to another machine which needs access to the internet. I'm trying to create a bridge so that the second machine on eth3 can be connected on the lan. I've tried the following, however it hangs when attempting to get an IP address from the router. Likewise, attempting to give it a static route doesn't seem to work either.
$ sudo aptitude install bridge-utils $ sudo ifconfig eth2 down $ sudo ifconfig eth3 down $ sudo brctl addbr br0 $ sudo brctl addif br0 eth2 eth3 $ sudo dhclient br0 # this hangs and fails to get a dhcp address
I've tried to ensure my routing table mimics what it looks like when using eth2 normally, I cannot hit the gateway at all.
$ route -n Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface 192.168.0.0 0.0.0.0 255.255.255.0 U 2 0 0 br0 0.0.0.0 192.168.0.1 0.0.0.0 UG 0 0 0 br0
I attempted an 'arping' to the MAC address of the router while I had eth2/3 bridged, but it failed to obtain it's IP address as well. One interesting thing I noticed was that attempting to bring down the bridge & reactivate my internet on eth2, I was having trouble pinging the gateway. It turned out 'ipmasq' had been installed and was running causing odd problems. When I stopped the ipmasq service, my internet started working properly again. I removed the 'ipmasq' package entirely and tried bridging the NICs again thinking it may have been causing problems, but it still failed.
I use a static compiled kernel and a fully encrypted disk apart from a boot partition. I have recompiled and installed kernels many times. When I tried with the latest kernel from Testing, 4.2.6, the system will not boot. Not only that but the previous kernel now does not boot. However, a stock modular kernel does boot. The static kernel hangs at:
Code: Select allVolume group "dk" not found Cannot process volume group dk /run/lvm/lvmetad.socket: connect failed: No such file or directory WARNING: Failed to connect to lvmetad. Falling back to internal scanning. Reading all physical volumes. This may take a while... /run/lvm/lvmetad.socket: connect failed: No such file or directory
[Code] ....
And after giving the password the boot continues successfully. How to diagnose it further?
I have a weird problem with my /etc/network/interfaces configuration. I have the most simple static setup possible: Code: # cat /etc/network/interfaces
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?
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.
I have two interfaces, gprs0 and gprs1, both connected to the Internet from the same HW device, but through two different access points I just read another blog entry with a guy who had two network cards, using one as a back up - I guess this is a little similar, but should be much easier I am guessing - I am just lost Using ifconfig (IP address given by the network) and route to setup the connection,
ifconfig gprs0 10.20.30.40 up route add default dev gprs0 ping 66.102.7.99 works fine afterwards
[code]....
There is data being transmitted and received to device again, I guess the kernel just doesn't know where the incoming data should go without the correct routing tables? Or what exactly is going on?The question I have is how do I configure the device to do the correct routing, using only the ifconfig and route commands? Maybe too trivial for you guys, but I am getting tired of goofing around not knowing what is up and down anymore
If I try to add a new interface (eth1) to /etc/network/interfaces, I get
Code: * Reconfiguring network interfaces... SIOCSIFADDR: No such device eth1: ERROR while getting interface flags: No such device SIOCSIFNETMASK: No such device
[Code]...
How do I add 2 interfaces and get anyone of them to work, as available ?
I just did an apt upgrade and for the most part everything is looking good. However when I boot up I have no network connection. Here is the result of trying to ping google: connect: Network is unreachable
I can fix it easily with a simple sudo dhclient eth0 but I was hoping someone would be able to suggest a more correct and less annoying solution. I have uninstalled network manager. This is a desktop computer with an ethernet connection and DHCP. I do not need anything fancy.
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:
I can't seem to get this to work without having to physically create connections as root. The "Available to all users" in the nm settings box remains uncheckable, despite completing the following tasks:
I'd like configuring NTP service on my Lenny Debian client to retrieve time from my local NTP server, so I thought to configure /etc/ntp.conf and to insert into crontab this command 'ntpd -qg', which is indicated in man. Can I run ntpd service to synchronize time for my client, avoiding to listen on port 123, beacuse my scope is to alignment time on client and to not give service to others, for this scope there is ntp server !
Today I decided to include again Debian Volatile and discovered that it doesn't exist anymore and that I can get the same packages using this line: deb [url] squeeze-updates main
And the first question is: is this the same than debian-security?
Then, I decided to use [url] to make things less confused, and this was the output:
The first line is Ok. The second line, I guest it's the same than my second line. But, the third, is something different. So, the main question is: what is the difference between squeeze-proposed-updates and squeeze-updates? Are those repos completely separated from squeeze/updates (in security.debian.org)? And, what else should I add to have an always up-to-date and secure system?
How do Linux identify the eth0, eth1, eth2 interfaces. For instance I plug in a network cable in to an interface. How do Linux recognize the plug in interface is eth0 or eth1?
I'm having trouble with my keyboard functions on my netbook (eeePC 1005HA running squeeze/sid - specific build being the one available on December 23rd 2009 - hasn't been updated since installation) - specifically, some of the function keys seem to be off - i.e. when pressing Fn+key, only some actually work. The specific ones I'm having trouble with are: Fn+F10 (mute)Fn+F11 (vol. down)Fn+F12 (vol. up)
As far as I can remember, they've never worked; at first I thought it wouldn't be an issue for me, having the volume panel, but the more time goes on, the more annoying it's becoming. Also, as it was a M$ machine at purchase, it has a Windoze key on it, which I'd like to configure to actually do something useful - preferably to open the main menu, if possible - but have so far failed to find any guides on how to do it. (Have Googled on multiple occasions, to no avail.)
First off I am aware ureadahead isn't in the repos, but thought this forum would fit the best regardless. I installed upstart, then the deb package on packages.ubuntu.com and rebooted. The /var/lib/ureadahead folder exists but there are no .pack files in that folder. I tried running "service ureadahead start" but it said "Service failed to start". Anyone used ureadahead on Debian?
I had some trouble with the netinst CD and I had to install lenny with the 6DVDs instead. My internet connection only works after I edit the interfaces and resolv.conf files manually. So my question is: can I do that from the netinst CD before it actually needs the connection to install everything? (otherwise I'll just need to use the DVDs.
This time I'm attempting to get Xorg up, and running. I've done a minimal Debian install from a network install disc. I used aptitude the install the following, with the dependencies configured automatically I assume:
- xorg - openbox - xserver-xorg-video-n (Where n is your graphics card family)
I've rebooted, and no X. I've typed in 'xstart', with no result. I've even typed in 'Xorg' at the CLI where it loads to a black screen, and hangs. I had to power off the PC by holding down the power button.Is there something I'm missing to configure/run it for the first time?
