Debian Configuration :: Eth0 Link Down On 6.0.2 When VoIP Phone Is Used?
Jul 20, 2011
I recently set up a Debian-based gateway+router on a remote site. I've installed OpenVPN and made a VPN bridge to another network (that server is also Debian). The main network has all the resources and also a VoIP server (asterisk). Bridge seems to work fine, except that every time a Linksys phone is used to call - after a few seconds I get:
Jul 20 12:16:05 sklad kernel: [403987.817695] eth0: link down
Jul 20 12:16:05 sklad kernel: [403987.817939] br0: port 1(eth0) entering disabled state
Jul 20 12:16:07 sklad kernel: [403990.113701] eth0: link up, 100Mbps, full-duplex, lpa 0x4DE1
[Code]....
So whenever the phone is used, network falls down for a few seconds. And of course this breaks the call. There is also another Linksys box (analog-to-voip) and it works fine most of the time. However sometimes this "eth0 link down" happens too. There is nothing more in syslog to analyze, so I don't know where to dig. Physical device of eth0 is D-link DFE520.

I am looking for a way to use my computer as a regular landline telephone not by VoIP but by actually dialing on my landline to talk. I don't know what software I need. My searches only bring up VoIP stuff leaving me stuck without answers. I am using a new installation of debian 5.0. I think that's all, if you need more details I can add them.

I have installed 2 VoIP programs, skype and xten softphone (X-Lite), skype works well and no problem but on the xten softphone not so lucky, I get to hear the tone before dialing like any phone but can't receive calls and if I call, there's no sound, other side can hear me, but I can't hear a thing.
I need both, skype it's my personal account and xten softphone is for work.

I am wondering if there is free VoIP software which will allow me to make and receive calls to regular phone numbers, such as landlines or cell phones, at no additional charge.

I've bought a Conceptronics CPHONELU (C01-200) VoIP USB phone. I would like to take full advantage of my VoIP phone in Linux. Currently I'm using Sip Communicator as the softphone, but I tried x-lite 3.0 on Windows too. The phone works has like a regular headset, I can hear and speak without a problem. However I cannot take full advantage of the phone, since the phone keyboard only work in Skype through the Skype Portal software that come bundle with the phone (Windows only). Is there a driver that I can use in order to be possible to dial using the phone and display the called ID with a regular softphone?

Today my boss come to me and ask me to get a cote to upgrade our old "Cisco call manager" (2004) now "Cisco Unified Communications Manager". So I was wondering, instead of doing a costly upgrade (over 35 000�), maybe it's time to change... Does anyone of you got some insight with Asterisk in an enterprise environment? Is it reliable? Following you own judgement, what are the + and - ? If Asterix worth it, what argument (apart of the price) could I use to help the management turning on my side? Will the Cisco 7921 VOIP phone will be able to connect to it? (as we do have over 35 of them)
Enterprise environment:
- 3 sites (VPN interconnected)
- ~35 VOIP phones and ~10 landlines phones

I have an adapter eth0 I need one shared folder to exchange files, with another machine configured as 192.168.0.3/255.255.0.0
ping is working fine between both machines, but I think my problem is in routing, or I need to add a shared resource and I am having trouble with that... not sure if maybe I need to mount something as nfs or what?

I installed Debian Squeeze on my system two days ago, using a wired connection to internet (which worked fine). After that, I had to install the non-free wireless package in order to scan wireless networks. It now works fine, and I can connect and get to internet. But with wired connection, i connect via eth0 and none of my applications work. And they're not in offline mode.Also, i already went here: URL,,, and I checked if that was my case. I tryed what they say several times in some different ways, but I still can't connect. Even more, if I change something like they say, I get "unmanaged device" and I can't even connect to the internet. And the wired connection works, I'm using it right now on my ubuntu 10.10.
If you want more information, I just tried to ping sites like google.com or ......com using network preferences and it does work, it gets 100% of the packages back around 50ms later, so the internet appears to work. Also, when I connect via wireless, everything works perfectly.

I noticed that when my server boots up, it's network interface on eth0 is always down and I always must run the 'ifup eth0' command in order to get it to work for some reason. I checked my configuration and it looks legit to me...
# This file describes the network interfaces available on your system # and how to activate them. For more information, see interfaces(5).

Anyone know why my system is booting with out bringing up my eth0 interface? It's very annoying.

I am running : Linux ics385 3.16.0-4-amd64 #1 SMP Debian 3.16.7-ckt11-1+deb8u6 (2015-11-09) x86_64 GNU/Linux
Here's the situation
1. I'm trying to configure a WLAN using a D-Link DLR655 wifi router that is connected to eth1.
2. eth0 is connected to the ISP's DHCP router and has the IP 192.168.0.24
3. I've bridged eth0 to eth1 such that eth1 has the static IP 192.168.8.1
4. I've manually configured the router and it uses the 192.168.8.1 as the WAN address with its subnet on the 192.168.10.* address space.
5. I can connect a laptop to the D-Link using wifi and ping 192.168.8.1 but I can't ssh to it or to anything beyond it from the laptop.
6. If I'm on the server (192.168.0.24) I can ssh into either 192.168.0.24 or 192.168.8.1 but not if I'm on the laptop. I conclude from this that ssh is not the problem but the laptop says ssh: connect to 192.168.8.1 port 22: connection refused.
So, am I conceptually confused or is it that I have to open ssh up to the other sub-net address spaces or something like that?

I am very new to linux.I have a network camera which only has an Ethernet port but no WiFi. Sadly no Ethernet port is available close to the camera.
Therefore I now bought a raspberry pi and installed raspbian to create a bridge into the wireless network, for connecting the camera to the internet.I now played around with the interface- and bridge configuration but I have problems with it.This is how my interfaces file looks like:
(The WiFi is secured with WPA2 Enterprise)
Code: Select all# interfaces(5) file used by ifup(8) and ifdown(8)
# Please note that this file is written to be used with dhcpcd
# For static IP, consult /etc/dhcpcd.conf and 'man dhcpcd.conf'
# Include files from /etc/network/interfaces.d:
source-directory /etc/network/interfaces.d
[code]....
The WiFi is connection works fine and I am in the internet using the WiFi.But I am wondering about eth0. The network parameters I specified are not the same as the parameters ifconfig tells me.Ip, Broadcast, Mask, nothing is as specified.It would be nice to give the camera a static IP that I can access it always with the same IP from the RaspberryPi.The Raspberry Pi itself gets always a new IP from the WiFi network. How do I get the camera into the internet using the existing connection of the Pi?

A few months back I performed a routine aptitude upgrade on a Squeeze installation on a DELL Vostro desktop. My eth0 upload speed is now very bad although download speed is good. I suspect that it could be related to my other problem [URL] which was caused by the OS enabling noveau driver instead of the installed NVIDIA proprietary drivers.
dmesg says:
eth0: Tigon3 [partno(BCM57788) rev 577880001] (PCI Express) MAC address 00:26:2d:23:a0:a5
eth0: attached PHY driver [Broadcom BCM57780] (mii_bus:phy_address=300:01)
eth0: RXcsums[1] LinkChgREG[0] MIrq[0] ASF[0] TSOcap[1]
eth0: dma_rwctrl[76180000] dma_mask[64-bit]
Where do I start to troubleshoot?

My installation has stopped detecting my wired network. Another computer connects fine with the same cable to the same access point. As far as I can tell it is simply behaving as if there was no network available from that cable but obviously there is. It was working a couple of hours ago, and I didn't install or uninstall anything, just shut down and booted up again.
LAN is enabled in the BIOS ifconfig does display eth0 ifup eth0 returns "Ignoring unknown interface eth0=eth0" in the output from dmesg:
"ADDRCONF(NETDEV_UP): eth0: link is not ready"
network appears in lshw and is not listed as disabled

I added an init script numbered just before bind9 starts, which needs to see the ipv6 link-local address on eth0. Sometimes this address is not configured, yet. In all cases it eventually is configured.
I am unable to find any script that is configuring the ipv6 link-local address (which is in part based on the MAC address). Does anyone know if there is some script or program that is supposed to be doing this, or is it an internal kernel function?
One workaround I am considering is making this init script go into a loop around sleep 1 to keep checking for the ipv6 address. But I'm concerned this might cause some problems. Any suggestions? I don't want to let it move on to start bind9 until the configuration this script does (more ipv6 addresses) is done.
This is on Ubuntu 9.10 server (for which there is not a prefix choice).
