Any hints why I'm getting the following message: dhclient: Internet Systems Consortium DHCP Client 4.1.1-P1 dhclient: Copyright 2004-2010 Internet Systems Consortium. dhclient: All rights reserved.

I have a dynamic Internet connection. My eth0 is configured to DHCP client. I need to rum one personalized command all time the dhclient renew the lease. I have a program that update the /etc/hosts with the new IP and I need to run this command when dhclient receive one lease update.

When I try to initialize classes (using the variable type and the variable, followed by the class's arguments [three unsigned 8-bit integers] in parentheses) and try to compile the Vala code to C code what I tried to AVOID doing, as I really wanted to create a shared object file, but now I know I have to use C code as a middleman, the compiler tells me it expects a semicolon between the class variable name and its members.
What?! A semicolon in a bad place, that's for sure! Why would I want to put a semicolon *BETWEEN* the class initialization and its members? Isn't the whole point of a class to *HAVE* different members? Here is my class:

My network configuration is in a weird situation, that I always need to run dhclient manually each time after a network connection is established. When my computer connects to a router, sometimes it won't get a valid IP, and it uses an automatically generated fake Internet IP. In this situation, it won't connect to the Internet at all. Sometimes it get a valid local network IP, but still cannot connect to WAN, and could only connect to my router's address (both through ping and through router's management webpage). In both situation, it can be solved by a simple dhclient run.
This is my /etc/network/interfaces file:
Code: Select all# 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

# The primary network interface

View 1 Replies View RelatedMy laptop only has a 100Mbit ethernet port, so I bought two external USB gigabit ethernet dongles in the hope of getting faster ethernet speeds. I have never had trouble with Linux supporting ethernet before, but neither of these devices are working. One is an ASIX AX88179 (by TrendNet) and the other is a Realtek RT8153 (by Anker). When I plug these devices in, I get network devices called enx00e04ca82300 or enxd8eb97b61e4d (instead of eth0/eth1 as I would expect).
I can manually set an IP address with "ifconfig enx00e04ca82300 x.x.x.x up" and manually add a route and my network connection works at gigabit speeds. However, the long enx... network device name does not appear to be valid in some sense: tools like dhclient or iptraf or network-manager fail with messages like "no such device" (well, network-manager just hangs). I don't know if it's because the name is so long or because they are not fully registered inside the kernel.
I have vmware workstation installed, and it does some strange things with network devices (setting up bridges for everything). I have disabled its services and see the same behaviour. This looks like a kernel bug to me but it's possible it is a vmware issue. vmware works fine with my wireless and 100Mbit ethernet (eth0 and wlan0).
Realtek device
Some dmesg for the Realtek device:

The Realtek device often crashes after just a few gigabytes have been transferred, with dmesg like this:

I have not investigated the ASIX device as much. However, my original 100Mbit ethernet has an ASIX chipset (AX88772) and that works perfectly. I have not observed the ASIX device crashing yet so I am using that for now (haven't used it for long yet though). But as before the device name appears to be invalid and I cannot run tools like dhclient. why two gigabit adapters with completely different chipsets would show up with long device names and support low-level stuff like ARP, ping, and static IPs, but fail with dhclient & network-manager? And the Realtek device seems to like crashing too.
I have a script generating some containing multiple lines. But I want to merge all lines using comma separated.

Looking at syslog (below), if its a hardware (network card) problem or a software bug?
syslog file:

I have a hard wired ethernet connection on a Desktop PC with a static IP address (there are a number of devices in the house) and it has been running 100% for months and months. Why suddenly do I have to enter this command to get connection? When I switch on I get a connection in that when I click on the Top Panel icon and right click Connection Information it tells me I have an active connection to my router on the normal IP address. I cannot ping the router and Firefox says Server not found.

I utilize the dhcp server in Debian to hand out IP adressing for around 2500 clients. It works flawlessly except that the lease tables dont seem to release expired leases. I have tried setting shorter lease times with no luck. I can manually delete expired leases.
View 4 Replies View RelatedI 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.
Freshly installed Lenny system. Edited /etc/network/interfaces to use a static IP:

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...

View 1 Replies View RelatedI 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 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?
how do i stop eth0 from starting up when i boot/login ??
View 4 Replies View RelatedA 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.

I have defoptions=quiet in my menu.list file and it keeps printing
ignoring bad line 1 'powernow-k8' across the screen during boot. The thing is that I have removed that line from /etc/modprobe.d/options, so why do I keep getting the warning?
I wanted to be able to have a boot option to just use a command line with no X running at all. What I did was remove the gdm3 link in rc5.d . Then in /boot/grub/grug.cfg I made a new menuentry that is exactly the same as the default but I changed this line:
linux /boot/vmlinuz-2.6.32-5-686 root=UUID=3e926e70-cb92-4847-997c-37aabda532ff ro quiet to this line: linux /boot/vmlinuz-2.6.32-5-686 root=UUID=3e926e70-cb92-4847-997c-37aabda532ff ro 5
This worked. It gave me a command line interface with no X running.
My question is is this the recommended way in Debian? If not what is?
I have been using Linux for a very long time but I used mostly Slackware. I tried Redhat for awhile but really hated bluecruve, shows how long I have been using Linux. I have played with other distros but I always went back to Slack. But I really dislike KDE4 so Slack is no longer an option. KDE4 reminds me of a 12 year old girl that got a big box of makeup and had to use every bit of it. I now am using Debian on my laptop. And as aside I gave my 16 year old daughter a laptop for her birthday. She used the included version of windows 7 for awhile but then asked me what would be a good Linux distro for her. I showed her distrowatch and told her to look at the top distros. She then asked me to help her put on Debian. She loves it. She is a very good musician and song righter, She actually gets paid for doing that at 16, and really likes the programs in Linux to work with sound files. She also does MIDI stuff with our Yamaha Clavinova.
Now we are trying to do things the Debian way and it is a little different then other distros. So did I do the command line thing they way it's recommended in Debian. I have looked on line but all I could find was working in a shell and that is not what I was looking for.
On my machine (Desktop PC) I have 2 network card : wireless (rt61 802.11) and a wired card (BCM44). When I install debian 5.
The wired card is detected and logical name eth0 is assigned, while wireless is not assigned I install firmeware* software to configure the card. It is done in some way ( I used mnetwork from mepis, it works fine).
Now the problem: eth0 disapears, and no eth0 inteface found? ifconfig gives just wlan0.
Question: Why there is no eth0, it was before configuration of wlan0 ?
How to active again eth0, or ho to create the logical eth0?

View 2 Replies View RelatedI've upgraded a server on our LAN from fully functioning Wheezy to Jessie. All seems fine except remote administering using Putty from my windows workstation when issuing reboot from command line, it goes down and reboots but stops at login prompt asking for username and password and does not come back on the LAN network. This server does not normally have a monitor or keyboard so my ability to remote admin this server in effect is disabled.
If I log on, it will come back on the LAN network. I've checked the logs but can't see any errors. Is it in the configuration of Jessie somewhere or perhaps a Grub issue. I have 5 other production Wheezy servers that I intend to update to Jessie once I understand how to deal with this problem.
