We've started having a problem with a CentOS 7 server. It looses its IPv6 address, if I understand this issue correctly. We can get in, if we do ssh -4, though. In the logs, I'm seeing this about twice an hour: <warn> (pid 98466) unhandled DHCP event for interface ens3f0 Now, in googling, I get very few hits putting quotes around "unhanded dhcp exception" - in fact, the

Hi, The use-case is deploying C7 VMs with a pre-set machine-id and default-duid based on the machine-id to facilitate static DHCP with IPv6. The default-duid is found in dhclient6-<value>-eth0.lease and IPv6 DHCP uses default-duid like IPv4 DHCP uses MAC addresses for static DHCP. How does one convert /etc/machine-id to a default-duid (in bash)? 1) /etc/machine-id -> DUID: <read

Hello, I''m using shorewall-4.5.16 with centos5. The dhclient stores the lease information on the /var/lib/dhclient/dhclient-<DEVICE>.leases file. The /var/lib/shorewall/firewall script has the function detect_dynamic_gateway that detects the gateway based on the leases file. The code in the function is: detect_dynamic_gateway() { # $1 = interface local interface

NM tends to log fairly verbose information. It sounds like

While troubleshooting my MultiISP box, I suspect I might have found either a bug or an incompatibility with CentOS 5.2. In prog.header (function detect_dynamic_gateway), Shorewall tries to look for: /var/lib/dhcp/dhclient-${1}.lease However (at least under CentOS 5 - unknown about other OSes), this should be: /var/lib/dhclient/dhclient-${1}.leases (different path, and "leases"

Hello! I want to SSH from host to specific guest using hostname, e.g. ssh <user>@<guest> or ssh test@vm02-fai ssh to guest using IP works w/o issues. I found Wiki article for "NSS module" (http://wiki.libvirt.org/page/NSS_module), but there are no results for the following commands: ld4004:/home # virsh net-dhcp-leases default Expiry Time MAC address

Hi all :-) on centos 6 I need keep the hostname from a dhcp server: cat /etc/sysconfig/network-scripts/ifcfg-eth0 DEVICE=eth0 HWADDR=00:50:56:27:0E:C8 TYPE=Ethernet UUID=20924b21-e92a-4944-a054-06d1967155c1 ONBOOT=yes NM_CONTROLLED=yes BOOTPROTO=dhcp PEERDNS=yes with this config, centos keep only ip from dhcp server (not gw, not dns) where is dhclient.conf? I need to create it? If yes,

Hi all, I am having an issue where my hme0 interface is always turning up and down with dhclient requesting a lease. I am thinking this could be the same issue described by Jeremy Chadwick on June 9th: http://lists.freebsd.org/pipermail/freebsd-stable/2013-June/073711.html Everything was fine on 8.2-STABLE and older versions. It was then upgraded directly to 9.0-STABLE

Hello Is there a way for the dhcp client to send the current host name of the machine when requesting a lease ? Currently I have to include a line like DHCP_HOSTNAME=appserver2 in my /etc/sysconfig/network-scripts/ifcfg-eth0, but I would like to tell the dhcp client to just 'also send the hostname' and then the client to get the current hostname itself, instead of having the name

Hi, Summary of problem: Local mail on the firewall stopped working after installing shorewall Background yesterday I installed shorewall, based on the debian package from www.backports.org (which seems to be a 2.0.3 package) on an otherwise virgin debian woody set up. Configuration was done based on the two-interface setup. Kernel is 2.6.8.1 unpatched. A 2.4.23 kernel, with

Hello All, I'm installing some DIY routers, composed of Intel nuc's ,Linksys usb-ethernet adapters and Centos7 On most machines I just plug in the usb device, install Centos7 and everything works.
