Dhcp not updating lease Free sex dating sites in ghana

14-Nov-2019 09:49

For testing purpose, I had set the lease expiry to minimal time.

so after the quick lease expiry,if at all there is a change in the gateway information on dhcp-server, it gets reflected appropriately on the client's leases file but not in the routing table.

Information The steps in this post shows how to configure the DHCP server to automatically update the DNS records when giving out a new lease to a client computer. Before continuing These steps assumes that you already have a working copy of isc-dhcp-server and bind9 installed.

If you don’t have that I suggest that you first read my two other posts on how to install them: Setting up a DNS for the local network on the Ubuntu 12.04 (Precise Pangolin) server Setting up a DHCP server on Ubuntu 12.04 (Precise Pangolin) server Step by step instructions Apparently the Ubuntu server is installed with an App Armor profile that prevents bind to write to the /etc/bind directory.

It is my understanding that the dhcp client is supposed to renew the lease when half the expiration time has gone by, and several times after that if it needs to.

What do I have to do to get it to renew automatically?

Below log confirms the renewal happens every defined interval, Apr 29 dhclient[12270]: DHCPREQUEST on mgmt1 to 192.168.10.2 port 67 (xid=0x2b10e716)Apr 29 dhclient[12270]: DHCPACK from 192.168.10.2 (xid=0x2b10e716)Apr 29 dhclient[12270]: bound to 192.1 -- renewal in 31 seconds.[[email protected]]# cat /var/lib/dhclient/dhclient-mgmt1.leaseslease Lease file updation happens properly after the defined expiry interval, but the problem is with classless-static-routes, if there is any change with the parameter ("classless-static-routes" new gateway) leases file holds the updated information but not the routing table, can see that from the below table:[[email protected]]# route -n Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface169.254.169.254 255.255.255.255 UGH 0 0 0 mgmt1Leases file hold the updated information but routing table is not aware of the change happened within the existing route.

Questions:should dhcp-client script update the routing table as well if any change that happens with the existing route information? DHCP client version : [[email protected] ~]# dhclient --version to get current and retest afterwards.

option domain-name "home.lan"; option domain-name-servers lan; default-lease-time 600; max-lease-time 7200; # If this DHCP server is the official DHCP server for the local # network, the authoritative directive should be uncommented. 5.1 Remove the general read rights from the configuration files: The dns database files are now being rewritten by the bind service.

Well that's harder to answer with the information presented.

Does the DHCP client ask for the route(s) (at both lease and renewal)?

The default profile suggests that these files should be put in /var/lib/bind.

If you have followed the steps in my previous post you might have your zone database files in /etc/bind/zones.
