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

Summary: if you have C5 guests with dhclient "bad udp checksum" issues then this entry on the host will fix it: iptables -A POSTROUTING -t mangle -p udp --dport bootpc -j CHECKSUM --checksum-fill Detail: If anyone else is seeing this...

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"

Hi, I have CentOS 7 and I am trying to get dhclient hooks working. I have 1) created file /etc/dhcp/dhclient-enp4s0.conf, 2) created directories /etc/dhcp/{dhclient-enter-hooks.d, dhclient-exit-hooks.d}, 3) added line 'DHCLIENTARGS="-nc"' into file ifcfg-enp4s0 and 4) added file /etc/dhcp/dhclient-enter-hooks.d/test with line echo "executed enter-hook", 5) but I was

It seems that the prominent North American Enterprise Linux vendor has decided that dhclient.conf should be ignored, i.e. ifup-eth causes dhclient to be called with "-cf /etc/dhclient-$(DEVICE).conf", and then ifup-eth/ifdown-eth wipes the file out each time. Through the use of "DHCP_HOSTNAME" in ifcfg-eth0 you can specify a host name, but because of the above behavior of

SELinux is preventing 11-dhclient from add_name access on the directory chrony.servers.wlp8s0. ***** Plugin catchall (100. confidence) suggests ************************** If you believe that 11-dhclient should be allowed add_name access on the chrony.servers.wlp8s0 directory by default. Then you should report this as a bug. You can generate a local policy module to allow this access. Do allow

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

Hi all. I recently turned net.inet.udp.log_in_vain on on some of my boxen and have been seeing UDP connection attempts to port 67 on the local host. This initially seemed odd, as the target ip addres was indeed that of a DHCP-configured interface and the source address was that of my DHCP server. However, it turns out this is totally valid, as dhclient(8) does not bind(2) on the bootpc port but

I had tried this approach, to add /etc/dhcp/dhclient-enter-hooks.d/resolved to excludefiles, however it didn't work. As far as I know, this hook is included in the base image and according to [1], the current implementation does not apply excludefiles to the base image.

hello logcheck team, is there a reason why no dhclient patterns are provided in ignore.d.workstation? in ignore.d.server there are all necessery pattern for dhclient, but a workstation typicaly uses dhcp an those messages reported by logcheck are annoying. are there any good reasons not to include dhclient patterns in ignore.d.workstation or are they simply missed? thank you for any feedback!

qemu in SLIRP mode offers DHCP services to the appliance. We don't use them, but use a fixed IP address intead. This changes the appliance to get its IP address using DHCP. Note: This is only used when the network is enabled. dhclient is somewhat slower, but the penalty (a few seconds) is only paid for network users. We could consider using the faster systemd dhcp client instead. ---

I recently reconfigured some CentOS 4.3 systems that were using DHCP to use static IP addresses. At the same time, the systems were moved to a new VLAN. Here is the approximate sequence of events that took place: 1. ifdown eth0 2. edit /etc/sysconfig/network-scripts/ifcfg-eth0 with static IP address 3. wait for network folks to reconfigure switch 4. ifup eth0 I may have

Hello, I have a problem which is that some of my VMs are loosing there IP addresses from time to time. What I saw in the log is when this VM loose its IP address there are DHCPREQUEST send from the VM by dhclient and the server responded only 50 minutes later ! Any help, advise on how to debug would be welcome. Thanks in advance Patrick Here after is an extract from the log July 1st 2016,
