CentOS - Oct 2015 - CentOS 7 & dhclient hooks

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 not getting any output after executing ifdown enp4s0 && ifup
enp4s0.

However, I was able to do this with NetworkManagers dispather scripts,
but I prefer old school dhclient hooks. :-)


sincerely
Tero M

Did you check the log files /var/log/daemonlog, /var/log/messages
journalctl ...
