Hi Daniel. I re-enabled my eth0 (wired) connection and restarted networking, and am again seeing a steady stream of messages from dhclient every 4 minutes or so.

Still true on Ubuntu 12.04. You get the DHCPDISCOVER log line constantly, until the disconnected interface is taken down.

[Bug 190359] Re: dhclient continually seeks ip address on unconnected interface
Hi Robert, What is the contents of your /etc/network/interfaces? I had the following: allow-hotplug eth0 iface eth0 inet dhcp Which caused this to happen. This is on a Debian system, but I'd be surprised if it's not the same issue. My "fix" was simply to remove these lines and let network-manager handle the interface. I would have expected ifupdown (guessing that's responsible) to be able to do cable sensing and not just keep trying. -- dhclient continually seeks ip address on unconnected interface https://bugs.launchpad.net/bugs/190359 You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to dhcp3 in ubuntu. -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs

[Bug 190359] Re: dhclient continually seeks ip address on unconnected interface
I'm suffering this on 9.10, although I didn't on 9.04 and earlier. I suppose, in fairness, I'm suffering this issue on a connected interface, unlike the original reporter, although I think it's the same issue and it causes problems for me: I connect to a network with a DHCP server and run: sudo dhclient eth0 and all works fine; I have an address and do what I want to do. Then I move to a network without a dhcp server and run: sudo ifconfig eth0 192.168.blah.blah/24 && sudo ip ro add default via 192.168.blah.blah And all works fine again; I'm connected to my new network and do what I want to do. Until a few minutes later when (according to /vat/log/syslog) the address is dropped and dhclient tries to acquire a new one. It fails and I'm left unconnected. Running sudo pkill dhclient solves the problem. I have run this exact setup / procedures on 8.04, 8.10 and 9.04 without suffering this behavior from dhclient. It's particularly annoying! jos...@joseph-work:~$ uname -a Linux joseph-work 2.6.31-14-generic #48-Ubuntu SMP Fri Oct 16 14:04:26 UTC 2009x jos...@joseph-work:~$ cat /etc/network/interfaces auto lo iface lo inet loopback -- dhclient continually seeks ip address on unconnected interface https://bugs.launchpad.net/bugs/190359 You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to dhcp3 in ubuntu. -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs

[Bug 190359] Re: dhclient continually seeks ip address on unconnected interface
I think I have the same issue on 14.04 Server, at least it appears to be the same issue. No network-manager. If the server is configured for DHCP and you later change it to static, the dhcp client daemon still goes out and requests a DHCP address. This impacts DNS for the device. The static IP remains on the interface, but the DNS record changes making it unreachable via hostname. The work around that I found, other than killing the dhclient process, is deleting the dhcp client database and rebooting. rm /var/lib/dhcp/dhclient.* You could probably just kill the related interface files if you wanted to. Based on the way this is behaving, I suspect its the same issue as not having the interface active. -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to dhcp3 in Ubuntu. https://bugs.launchpad.net/bugs/190359 Title: dhclient continually seeks ip address on unconnected interface To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/dhcp3/+bug/190359/+subscriptions -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs

I have a similar or same issue with Ubuntu 14.04.01 on a desktop with a Ethernet connection only that worked with Ubuntu 8.04 since 2006. Since updating, no internet. I decided to upgrade and did a clean install of Ubuntu 14.04.01 trusty and I NEVER had Internet again on this dektop. I am sure (tested) that the cable is OK, the hardware is OK, the internet connection is OK I have tried a lot of things and a long time spent with excellent support form the comunity in Italy via IRC did not solve the issue. uname Linux marco-desktop 3.13.0-32-generic #57-Ubuntu SMP Tue Jul 15 03:51:08 UTC 2014 x86_64 x86_64 x86_64 GNU/Linux dmesg|grep tg3 [1.156680] tg3.c:v3.134 (Sep 16, 2013) [1.230990] tg3 :03:00.0 eth0: Tigon3 [partno(BCM95789) rev 4101] (PCI Express) MAC address 00:0f:ea:4c:4e:1a [1.231000] tg3 :03:00.0 eth0: attached PHY is 5750 (10/100/1000Base-T Ethernet) (WireSpeed[1], EEE[0]) [1.231006] tg3 :03:00.0 eth0: RXcsums[1] LinkChgREG[0] MIirq[0] ASF[0] TSOcap[1] [1.231012] tg3 :03:00.0 eth0: dma_rwctrl[7618] dma_mask[64-bit] ifconfig eth0 eth0 Link encap:Ethernet HWaddr 00:0f:ea:4c:4e:1a 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 collisions:0 txqueuelen:1000 RX bytes:0 (0.0 B) TX bytes:0 (0.0 B) Interrupt:18 interfaces # interfaces(5) file used by ifup(8) and ifdown(8) auto lo iface lo inet loopback lshw -C network *-network description: Ethernet interface product: NetLink BCM5789 Gigabit Ethernet PCI Express vendor: Broadcom Corporation physical id: 0 bus info: pci@:03:00.0 logical name: eth0 version: 11 serial: 00:0f:ea:4c:4e:1a capacity: 1Gbit/s width: 64 bits clock: 33MHz capabilities: pm vpd msi pciexpress bus_master cap_list ethernet physical tp 10bt 10bt-fd 100bt 100bt-fd 1000bt 1000bt-fd autonegotiation configuration: autonegotiation=on broadcast=yes driver=tg3 driverversion=3.134 firmware=5789-v3.29a latency=0 link=no multicast=yes port=twisted pair resources: irq:18 memory:e400-e400 lspci -nnk 00:00.0 Host bridge [0600]: Intel Corporation 82945G/GZ/P/PL Memory Controller Hub [8086:2770] (rev 02) Subsystem: Gigabyte Technology Co., Ltd Device [1458:5000] 00:01.0 PCI bridge [0604]: Intel Corporation 82945G/GZ/P/PL PCI Express Root Port [8086:2771] (rev 02) Kernel driver in use: pcieport 00:1b.0 Audio device [0403]: Intel Corporation NM10/ICH7 Family High Definition Audio Controller [8086:27d8] (rev 01) Subsystem: Gigabyte Technology Co., Ltd GA-8I945PG-RH Mainboard [1458:a102] Kernel driver in use: snd_hda_intel 00:1c.0 PCI bridge [0604]: Intel Corporation NM10/ICH7 Family PCI Express Port 1 [8086:27d0] (rev 01) Kernel driver in use: pcieport 00:1c.2 PCI bridge [0604]: Intel Corporation NM10/ICH7 Family PCI Express Port 3 [8086:27d4] (rev 01) Kernel driver in use: pcieport 00:1d.0 USB controller [0c03]: Intel Corporation NM10/ICH7 Family USB UHCI Controller #1 [8086:27c8] (rev 01) Subsystem: Gigabyte Technology Co., Ltd GA-D525TUD [1458:5004] Kernel driver in use: uhci_hcd 00:1d.1 USB controller [0c03]: Intel Corporation NM10/ICH7 Family USB UHCI Controller #2 [8086:27c9] (rev 01) Subsystem: Gigabyte Technology Co., Ltd GA-D525TUD [1458:5004] Kernel driver in use: uhci_hcd 00:1d.2 USB controller [0c03]: Intel Corporation NM10/ICH7 Family USB UHCI Controller #3 [8086:27ca] (rev 01) Subsystem: Gigabyte Technology Co., Ltd GA-D525TUD [1458:5004] Kernel driver in use: uhci_hcd 00:1d.3 USB controller [0c03]: Intel Corporation NM10/ICH7 Family USB UHCI Controller #4 [8086:27cb] (rev 01) Subsystem: Gigabyte Technology Co., Ltd GA-D525TUD [1458:5004] Kernel driver in use: uhci_hcd 00:1d.7 USB controller [0c03]: Intel Corporation NM10/ICH7 Family USB2 EHCI Controller [8086:27cc] (rev 01) Subsystem: Gigabyte Technology Co., Ltd GA-D525TUD [1458:5006] Kernel driver in use: ehci-pci 00:1e.0 PCI bridge [0604]: Intel Corporation 82801 PCI Bridge [8086:244e] (rev e1) 00:1f.0 ISA bridge [0601]: Intel Corporation 82801GB/GR (ICH7 Family) LPC Interface Bridge [8086:27b8] (rev 01) Subsystem: Gigabyte Technology Co., Ltd Device [1458:5001] Kernel driver in use: lpc_ich 00:1f.2 IDE interface [0101]: Intel Corporation NM10/ICH7 Family SATA Controller [IDE mode] [8086:27c0] (rev 01) Subsystem: Gigabyte Technology Co., Ltd Device [1458:b002] Kernel driver in use: ata_piix 00:1f.3 SMBus [0c05]: Intel Corporation NM10/ICH7 Family SMBus Controller [8086:27da] (rev 01) Subsystem: Gigabyte Technology Co., Ltd GA-8I945PG-RH/GA-D525TUD Mainboard [1458:5001] 01:00.0 VGA compatible controller [0300]: NVIDIA Corpora
