cannot extend the waiting time for a lease offer

[garrik]

I am troubleshooting an issue where sometimes the DHCP server does not respond with a lease offer within 5 seconds, so dhcpcd selects the fallback profile. I am trying to increase the waiting time, so I set timeout in the dhcpcd.conf or via command line dhcpcd -B -d -w -4 -t 0 enp10s0 but it does not work. Am I doing something wrong?

Here is the dhcpcd.conf

timeout 0

profile static_enp10s0
static ip_address=192.168.157.2
static routers=192.168.157.1
static domain_name_servers=192.168.157.1

interface enp10s0
fallback static_enp10s0

and the log

fallback_time seconds Start fallback after seconds. The default is 5 seconds.

[garrik]

Thank you for the timely response. However, I’m getting an error: unknown option: fallback_time. I’m currently using version 9.5.2.

[perkelix]

Correct. The option was added sometimes during branch 10.

@garrik Does the above issue still affect you using newer dhcpcd releases?
