May 17 19:53:19 brick dhcpcd[12598]: dhcp6_listen: Address already in use
Can I get the full log plz?
See attachment.
Fun fact, I had to rename my computer name to get it past the spamhaus.org filter.
The filter I run on mail.marples.name?
Anyway, "waitip 4" in /etc/dhcpcd.conf also make the problem disappear.
Does dhcpcd signal wicd as soon an IP address (IPv6 in this case), has been received/set?
No, dhcpcd just exits 0
I think wicd checks for an ipv4 address at this point and when none found says it's an error and kills dhcpcd
Does it mean that dhcpcd exits as soon as an ipv6 address has been set and no ipv4 address yet?
By default yes, if the IPv6 provides DNS.
I'm pretty sure wicd doesn't like that.
Anyway, new patch to try and stop the listen error from happening.
This is a little more invasive and should create a core dump on error so
we can see how it's being called.
