Description Dmitry Karasik 2008-07-03 15:13:36 UTC 
Ever since I upgraded to dhcpcd-4.0.0_beta7 it has been letting the IP lease expire without renewing it, which causes services to stop working as my host name is unregistered from the DNS server.

In previous versions I would see entries in the log similar to the following every day:

Jun 10 20:18:44 wsdkarasik2 dhcpcd[1630]: eth0: renewing lease of x.x.198.85
Jun 10 20:18:44 wsdkarasik2 dhcpcd[1630]: eth0: leased x.x.198.85 for 86400 seconds
Jun 10 20:18:44 wsdkarasik2 dhcpcd[1630]: eth0: no renewal time supplied, assuming 43200 seconds
Jun 10 20:18:44 wsdkarasik2 dhcpcd[1630]: eth0: no rebind time supplied, assuming 75600 seconds


However with 4.0.0_beta7 I see a startup message:
Jun 20 09:22:10 wsdkarasik2 dhcpcd[32414]: eth0: dhcpcd 4.0.0-beta7 starting
Jun 20 09:22:10 wsdkarasik2 dhcpcd[32414]: eth0: hardware address = 00:0c:76:82:b0:64

Jun 20 09:22:10 wsdkarasik2 dhcpcd[32414]: eth0: broadcasting for a lease
Jun 20 09:22:15 wsdkarasik2 dhcpcd[32414]: eth0: offered x.x.198.85 from x.x.196.37
Jun 20 09:22:15 wsdkarasik2 dhcpcd[32414]: eth0: lease of x.x.198.85 acknowledged
Jun 20 09:22:19 wsdkarasik2 dhcpcd[32414]: eth0: leased x.x.198.85 for 86400 seconds
Jun 20 09:22:19 wsdkarasik2 dhcpcd[32414]: eth0: no renewal time supplied, assuming 43200 seconds
Jun 20 09:22:19 wsdkarasik2 dhcpcd[32414]: eth0: no rebind time supplied, assuming 75600 seconds


No subsequent renewal messages are logged.

I think I already have this fixed.
Could you test this snapshot please?

You can force a renew like so

dhcpcd -n eth0

beta8 is now out, where this should be fixed :)

If you can get a packet capture to match the log, that would be useful
Comment 6 Dmitry Karasik 2008-07-08 13:03:10 UTC 
beta8 fixes the problem for me.
