The following command works perfectly to start DHCP:
# dhcpcd -p eth0
DHCP cannot be stopped once it is started. The following command does not work:
# dhcpcd -k eth0
It returns the following:
dhcpcd[4700]: sending signal 1 to pid 4086
dhcpcd[4700]: dhcpcd not running
dhcpcd[4700]: kill: Bad file number
Could anyone offer a tip on how to kill DHCP?
A way to dynamically get the PID of the dhcp process, and kill it altogether, would be to run:
su
var=$(ps | grep dhcp)
kill $(echo -n $var | cut -d " " -f 0)
Specifically:
ps (which lists the active processes), filtered by grep with the keyword dhcp, to the variable var;kill to terminate the value contained in the first field (-f 0) of the variable var, by telling cut to separate the fields with a whitespace (-d " "). Not coincidentally, the mentioned value corresponds to the PID of the process dhcpcd.Q & A
