Debian Configuration :: New Router, Now "no DHCPOFFERS Received"?
Oct 22, 2010I'm getting some odd behavior from a new router (netgear wg614 i believe). It appears that it won't assign an IP address to any machine running linux, but it WILL assign an IP address just fine to windows machines. my laptop is running debian lenny, but it isn't just my laptop - other linux (or linux based) machines can't get an IP address from it, either (including my wii). yet my old windows desktop gets an IP address just fine, as do my friend's windows laptops. i did not have this problem with my old router. nor do i have this problem when i bring my laptop other places. i have this problem ONLY with this new router.
the workaround is to assign a static IP address to my laptop and my wii, which is fine, but... i still want to get to the bottom of it. my laptop is definitely associated with the router (iwconfig output confirms this), so it's not a problem with the card or the driver (right?). i can log into the router administration from my laptop. the router just won't give it an IP address. how can this be? considering:-the only thing that has changed is the router-the problem occurs with all non-windows machines-my laptop and wii both worked fine with my old router (and others), and the settings have not changed.so, is there something fundamentally different about how linux and windows request an IP address from a DHCP server? My knowledge of both linux and DHCP are "medium", and they don't overlap enough for me to figure this out, i guess.
Ubuntu Networking :: No DHCP Offers Received After Modem Change?
Jul 5, 2011I used to connect to the internet via a Linksys router using the following terminal commands (Network Manager has never worked for me on any Ubuntu install):
Code:
sudo ifconfig wlan0 down
sudo dhclient -r wlan0
sudo ifconfig wlan0 up
[code]....
However, I recently changed the old modem + router for a new wireless modem (a Thomson TG585v8 ). Now, the result of that last command is this:
Code:
amosupremo@amosupremo:~$ sudo dhclient wlan0
Internet Systems Consortium DHCP Client V3.1.3
[code]....
No working leases in persistent database-sleeping. I've tried to connect in Natty(both Ubuntu and Kubuntu) and it's not working either.I also purged Network Manager and installed wicd and I managed to get an intermittent, slow connection.
1 ) Machine Brand and Model (PC/Laptop): No brand. I built it with the following specs:
AMD Athlon II X4 2.6GHz
2 HD: 100GB Sata (Ubuntu and XP64 install) / 80GB IDE (XP)
4GB RAM
Gigabyte Motherboard
2 ) Wireless Brand, Model and Wireless Chipset:
Code:
amosupremo@amosupremo:~$ lsusb

3 ) check interface:
Code:
amosupremo@amosupremo:~$ ifconfig wlan0
wlan0 Link encap:Ethernet HWaddr 00:02:72:04:d0:04
[code]...
I am also attaching the wicd log. It contains a session where I got the intermittent connection. I stopped that connection and restarted it (with the same results) two times.
CentOS 5 Networking :: Error: No Dhcp Offers Received - Using Systemimager To Autoinstall System Images On Pc's Connected In Lan
Mar 10, 2009i want to resolve the above error. I'm using systemimager to autoinstall system images on pc's connected in lan. while doing this i got the error No DHCPOFFERS received. Also at the time of booting my pc it shows the message No dhcp and/or proxyDHCP offers recieved. But i've started the dhcpd deamon on my pc. Also the systemimager rsync deamon is running. The two pc's are also connected in lan properly.
Still while autoinstalling the image on client it fails showing the error message... No DHCPOFFERS recieved. what do i do in order to make my autoinstall work properly? How do i come to know whether the dhcp server is running or not? What will be the exact problem in autoinstalling?
Networking :: Connect Using An Ethernet Card Using Dhcp ?
Feb 15, 2010My ISP finished some 'upgrades' on its infrastructure. The result is that I am having great difficulty in connecting to the internet.
I have 3 operating systems on my box - XP, Fedora 8 and Feota 12.
I connect using an ethernet card, using dhcp. In fedora 12, the ethernet card is controlled be networkmanager. After the ISP completed their upgrades, I was not able to connect. I tried to connect manually using
Code:
There was an error message -
Code:
I read the advice here: [url], and removed all but the important lines.
But even after that neither ifup eth0 or dhclient eth0 works.
In fedora 8, the ethernet card is activated by ifup eth0 in /etc/rc.local. I was able to connect on a couple of occasions, but that too stopped working. I tried both ifup eth0, dhclient eth0, and tried to use the gui( which fires the dhclient command), but none worked.
When I use windows, it takes about 2 minutes to get an ip (earlier it was immediate). Sometimes that doesnt work and I have to click on "repair" whereupon it starts working.
Ubuntu Networking :: Configure Second Ethernet Card For A Dhcp/dns Server?

Ubuntu Networking :: TORK: TOR Stopped Talking To Us?
Mar 19, 2010I'm using Ubuntu Hardy x64 and when pressing "Play" in TORK, I get the following Message:
*TOR Stopped Talking To Us!!*Message: Did Something Happen To Me?
*This Means: Try Starting TORK Again. TOR Starts up in the background. and I have also tried killing TOR and then restarting it with Vidalia and verifying that TOR is running. I've also tried using the Wizard to configure TORK to no avail. It also does'nt seem to be able to write to the "torrc" file. Also, when I select Tools>Browse TOR Network Status, I get the following message:
*Could not launch the browser:*Could not find service "kfmclient." I suppose this could mean that I need to install some elements of KDE, but I have several KDE applications running on my installation, such as Amarok, with no complications.
Ubuntu Networking :: Wireless - 2 Puters Not Talking / Get Them To Work?
Feb 18, 2011I have installed MM 10.10 on a desktop (also running XP home) and a laptop (vista home prem).
Both have good access wirelessly to www using an orange livebox, via linux and windows.
But I can't get them to talk to each other for file sharing etc.
I'm pretty sure there's a simple solution but, as a novice to linux, it's beyond me at the moment.
Networking :: Iwl4965 Stops Talking Without Disconnect From D-Link Router
May 12, 2010I have laptops with intel 4965/AGN wireless hardware and ubuntu jaunty. My wireless access point, router, gateway is a D-Link DIR-655. The D-Link is directly connected to my cable modem. The connection does not drop, but They suddenly quit talking with each other. After a brief time lapse, they start talking again without intervention on my part. When I say "stop talking" this is behavior where a browser will return "page or server not found" errors or "DNS timeout". Has anyone seen this sort of network behavior and have some idea about corrective actions?
My attempts to get some help from D-Link have not been successful. Since there are not hundreds of folks reporting troubles, they don't [want to?] understand one poor souls problems.I've tried to ask about this several times and several places.
Ubuntu Networking :: DHCP Server No Longer Responses To DHCP Requests - Can't Ping Gateway
Oct 22, 2010Back in April I set up a Ubuntu DHCP server and a multiple VLAN network [URL] to migrate our various servers, workstations, etc off the 192.168.1.1 /24 network that everything was on because we where running out of address space. I built out the new network and everything worked great except our AD server would never get an IP address from the DHCP server (static reservation) and even if I set the IP statically on the AD server it couldn't ping the gateway and noone could log in. After several attempts to resolve this, including bringing in outside help, we where never able to figure out what the problem was.
Now 6 months later I have time to revisit the issue without effecting the live network. I used Acronis and imaged the AD server last Friday, cloned it on to another box with the same hardware, and put it up on the new network that's been sitting unused for the last 6 months. Today when I statically set the IP on the AD server (which is what I want) it connects and I can ping it's gateway 192.168.1.1 and all the way across vlans to a test sales agent workstation at 192.168.8.xxx on vlan 800 but only if I statically assign the agents station an IP address. When I try to get an IP address via DHCP it fails as destination unreachable. Nothing has changed in the last 6 months on the DHCP server but now it for some reason can't ping its default gateway 192.168.1.1. All of the config files are the same as they where left from the post linked above aside from the vlan id's used where changed from 1's to 100's (i.e. vlan 3 is now vlan 300) /etc/network/interfaces
Code:
auto lo
iface lo inet loopback
auto vlan100
iface vlan100 inet static
[code]....
why it can't reach the gateway, when I do a tcpdump I can see the DHCP requests come in on eth0 but the server never responds and I'm pretty sure its because it isn't "seeing" them since it thinks there isn't a network connection but I don't know how to trouble shoot to find out where the problem lies.

Ubuntu Networking :: If DHCP Not Available - Fallback And Start DHCP Server?
Mar 8, 2010Currently I have my eth0 interface getting a DHCP address but at times the DHCP server will not be reachable. Sooo what I would like my server to do is if it cannot find a DHCP server assign a static address to eth0. Then start the DHCP service so it can then dish out some addresses.How can I do this? Surely it is possible

Mar 25, 2010I am puzzled with trying to configure a linux (openSUSE) client to dhcp to eBox DHCP server. I am using dhclient to lease an IP address with dhclient eth0 -s 10.45.48.108 and get a response
openSUSE11232CL1 dhclient: DHCPDISCOVER on eth0 to 10.45.48.108 port 67 interval 4
openSUSE11232CL1 dhclient: DHCPOFFER from 10.45.48.108
openSUSE11232CL1 dhclient: DHCPREQUEST on eth0 to 10.45.48.108 port 67
openSUSE11232CL1 dhclient: send_packet: Network is unreachable
openSUSE11232CL1 dhclient: send_packet: please consult README file regarding broadcast address.
The server reports eBox141 dhcpd: DHCPDISCOVER from 00:0c:29:3e:57:a3 (openSUSE11232CL1.domain.net) via eth0
eBox141 dhcpd: DHCPOFFER on 10.45.200.2 to 00:0c:29:3e:57:a3 (openSUSE11232CL1.domain.net) via eth0
I interpret this as the server receives the request and the client accepting it but the lease does not last long and the connection breaks. what this could be and why the connection breaks? Or my undestanding is totally wrong on how it works and should work? And BTW, where is that README file that's referenced in the message I receive on the client?
Ubuntu Multimedia :: NVidia 8500GT Card Stuck In 640x480?
Jan 14, 2010I have just installed Ubuntu 9.10 Karmic on my HTPC, and it detected my TV (connected via DVI, so is a monitor effectively) OK, and displayed the proper resolution of 1360 x 768. I want to use the proper nVidia drivers which I've enabled using the restricted drivers tool in Ubuntu. On doing this, it has set the resolution to 640 x 480, and the nVidia configuration tool will not let me set it any higher.
1. The contents of xorg.conf are now irrelevant as of the last few versions of X?
2. The nVidia software is not reading the EDID information from my TV properly?

Oct 5, 2010This has been bugging me for quite a long time. I need to have a pptp connection to my university. I have tried to locate the error, but this has been a real trouble.
A little bit of history: My girlfriend had a laptop with M$ vista on it with a working PPTP connection. I had a laptop with Ubuntu, with which I couldn't get the PPTP working.
When my laptop crashed, I bought a new one on which I run a dual boot XP SP3 and Ubuntu. I also own a desktop (Dual M$ Win 7 / Ubuntu standard Karmic) and my girfriend also upgraded to Win 7.
Currently, the XP version is the only one on which I can get a connection. Both Ubuntu and the Win 7's give me a GRE proc 47 not received error. I know our router (a DAVOLINK DV2020) is notorious for not sending through GRE proc 47, but this either shouldn't be the case or it shouldn't matter, since I can make a perfect connection through the XP OS.
This is quite a handicap, since we both study at the university for which we require working VPN PPTP connections.

View 2 Replies View RelatedUbuntu Networking :: IP Address - No Responses Received For Pings
Aug 6, 2010I am having (seemingly) random trouble with my wired network ever since I installed Lucid. I have no problem getting an ip address from dhcp. However, randomly the computer will boot and although I have an ip address I do not receive any responses for pings on the network nor can I browse the web. If I sudo /etc/init.d/networking restart a few times (or reboot) it will start working. However, restarting the networking services (as mentioned above) again will cause me to no longer receive responses for pings or browse the web.
Furthermore, I have never been able to successfully ping if I manually set an ip address. I have un-installed network manager and I am using /etc/network/interfaces to configure the network. Using Lucid Lynx 64bit on a Dell Precision. I have pasted below the output of a few working commands. When I switch between static ip and dhcp I am commenting/uncommenting the lines shown in /etc/network/interfaces.

Ubuntu :: Laptop Refresh Rate Stuck At 50hz With Intel 965gm Graphic Card?
Feb 28, 2011I had an old thinkpad x61s laptop running ubuntu 10.10 with an intel gm965 graphics card. When i checked the monitor today it says the refreshing rate is 50hz and there is no other option available. I vaguely remember it used to be working at 60hz when I was running xp, so I googled and searched the forum for answers but came with no luck. Some people reported a similar problem with their nvidia graphic card and they seems to be able to modify a xorg.conf file to manually solve the issue (sadly I don't know how).

Networking :: Directly Access Received Packets In Buffer?
Mar 29, 2011where packets are stored when they're received. After some googling, I think perhaps libpcap with mmap would be the solution. Does libpcap 1.0 and above support mmap?From my understanding, mmap would allow me to directly access the buffer without having to explicitly copy the packet to another buffer for me to do processing. I would also appreciate it if someone can let me know where I can find examples of such applications, as many examples of mmap I've found involves mapping a buffer for file operations, rather than integrating it with pcap functions like pcap_loop, pcap_next_ex etc.

Networking :: Route All Traffic Received By An Interface To Another And Vice Versa?
Mar 2, 2011The task I am trying to complete is the virtualization of an IPv6 router created using two fedora machines. Here is the physical setup I have now...
PC1:eth0 <------> network
PC1:eth1 <------> PC2:eth0
PC1:eth2 <------> PC2:eth1
PC1 runs radvd to provide router advertisements to the network and a DHCPv6 server for stateful addresses.Each interface is configured on a separate subnet. PC2 runs a DNS server on eth0. PC2:eth1 is used as an IPv6 client for testing purposes. The connections from PC1 to PC2 are just crossover cables.I've created virtual machines of both PCs and have created 4 virtual adapters on the host machine for each of the local-only interfaces.Now I have this:
PC1:eth0 = HOST eth0
PC1:eth1 = HOST vboxnet0
PC1:eth2 = HOST vboxnet1
