Dhcp not updating lease - ver amor bravo capitulo 40 online dating

-G, --dhcp-host=[][,ignore] so the "--dhcp-hostsfile=/var/etc/hosts" option won't give desired results. This can make local DNS resolution to appear to be working when it's really not.This happened to me and then I started to use dig to test dns lookups.

The advantage of storing DHCP host information in this file is that it can be changed without re-starting dnsmasq: the file will be re-read when dnsmasq receives SIGHUP.But still, nothing but nslookup is resolving these hostnames.I haven't rebooted any of the machines since, so is it perhaps a DNS cache issue? I've applied Adam's patch, and I can verify that running /etc/rc.parse-isc-dhcpd does cause the leases to get added to /etc/hosts.For example, if you wanted to set up a separate DHCP zone for handing out addresses to untrusted wireless clients versus trusted clients, or if you wanted to do something more awesome like implement the Upside-Down-Ternet, you’d need something a lot more configurable than the little NAT router’s applications.There are lots of options, but it’s easiest to just pull out the big guns and set up BIND9, the current version of the DNS software that powers the Internet, along with the ISC’s DHCP server.nslookup from local machines works fine, as does ping.

Prior to the patch my /etc/hosts file only contained my static DHCP entries.

This lease file was written by isc-dhcp-V3.0.7lease 192.168.1.25 lease 192.168.1.21 lease 192.168.1.23 lease 192.168.1.19 lease 192.168.1.22 lease 192.168.0.244 lease 192.168.0.41 lease 192.168.0.243 lease 192.168.0.240 lease 192.168.0.238 lease 192.168.0.75 lease 192.168.0.235 lease 192.168.0.234 lease 192.168.0.242 lease 192.168.0.241 lease 192.168.0.233 lease 192.168.0.230 lease 192.168.0.237 lease 192.168.0.236 lease 192.168.0.15 lease 192.168.0.231 lease 192.168.0.232 lease 192.168.0.93 lease 192.168.0.239 lease 192.168.0.82 lease 192.168.1.23 lease 192.168.1.19 lease 192.168.0.93 lease 192.168.0.239 Here is the process still being displayed in ps: root 4356 0.0 0.1 3316 1060 ??

Is 6Jun10 .02 /usr/local/sbin/dhcpleases -l /var/dhcpd/var/db/dhcpd.leases -d adamsnet -p /var/run/dnsmasq.p Sadly I think we may need to reopen this problem for feedback :(.

The DNS Forwarder option "Register DHCP leases in DNS forwarder" does not work. I'm seeing the same as here: can tell you why the leases aren't going in /etc/hosts and have a pretty simple fix (although it's so shallow I'm not even going to post a patch file).

However, now that I'm getting the dynamic leases in the /etc/hosts file, I'm resolving them with nslookup on the lan, but no other network services resolve the host correctly.

If this is inconvenient or confusing to you, we sincerely # apologize. # The format of this file is documented in the dhcpd.leases(5) manual page.
