Hi, it seems that "ip address delete" will delete all addresses of the same class on an interface if it is ordered to only delete the first one: # ip a f eth0 # ip a l eth0 3: eth0: <BROADCAST,MULTICAST,UP> mtu 1500 qdisc pfifo_fast qlen 1000 link/ether xx:xx:xx:xx:xx:xx # ip a a 192.168.a.b brd + dev eth0 # ip a a 192.168.c.d brd + dev eth0 # ip a d 192.168.a.b brd + dev

Greetings, all: OS: CentOS 6.4 x86_64 Kernel: 2.6.32-358.14.1 I could use some assistance with setting up pulse to load balance my dns servers. I've configured tcp and udp port 53 with the piranha gui, set up arptable rules on the real servers and added the virtual ip to the bond0 interface on the real servers, but I'm still having no luck in getting things going. A dig against the

...Something else? Hi, on CentOS 7 you probably want to take advantage of the ability to put multiple config files in /etc/sysctl.d. For example this is what /etc/sysctl.d/50-network.conf looks like on one of my routers: # cat /etc/sysctl.d/50-network.conf net.ipv4.ip_forward = 1 net.ipv4.conf.eth1.promote_secondaries = 1 The other thing i would recommend is to replace the iptables script with the iptables-service package. That package uses iptables-restore to load the iptables rules from /etc/sysconfig/iptables on boot and you can use iptables-save to store the iptables rules there when you make changes. Th...

Hi, I just migrated my office's server from Slackware64 14.1 to CentOS 7. So far everything's running fine, I just have a few minor details to work out.
