[The process of the 2016-06-28]dhclient command did not kill, resulting in constant IP access to the DHCP server

# date:2016-06-28

# problem: The configuration file of the host/etc/sysconfig/network-scripts/ifcfg-eth0 has been configured with a static IP.

But every few minutes the host's IP has changed itself ...

Solution

View Log/var/log/messages

Discover that hosts are always getting DHCP-assigned addresses ...

To view a process:

[[Email protected] network-scripts]# PS aux | grep client
Root 4857 0.0 0.0 9116 1008? Ss 08:52 0:00 dhclient eth0
Root 7870 0.0 0.0 103252 840 PTS/7 s+ 10:01 0:00 grep Client

All right ... kill the dead.

[Email protected] network-scripts]# kill-9 4857
