The last version of dhcpcd which is working is: 3.0.16-r1. Any newer version is not able to get an IP adress at the company network. At home it's working with the same laptop, but at the company I have this problem. I have no control over the company network, and I have no idea about the dhcp server, my guess it's some kind of Windows. All Windows clients are working fine.

1) Please post your `emerge --info' too. 2) What brand/model/vendor etc DHCP server does your company network run?
Did you emerge dhcpcd-4 with the compat USE flag? If not you need to explicitly enable duid to get the same behaviour as dhcpcd-3. man dhcpcd or dhcpcd.conf to see how to do this.
The compat flag was enabled.

Could you attach wireshark dumps of dhcpcd-3 working and dhcpcd-4 failing please?
I put duid to the /etc/dhcpcd.conf, and nothing changed. Still not working. I don't know what kind of dhcp server the company have, and it's not easy to find out, because none of the IT guys in this site know about it. It's administered from another city, the burocracy is really big here, so probably I have to go through a lot of phone calls to get to someone who has any idea.
Created attachment 170072 [details] working 3.0 capture file
Created attachment 170074 [details] not working 4.0 capture file
(In reply to comment #7) > Created an attachment (id=170074) [edit] > not working 4.0 capture file The working one is sending a MAC address, the non working one not. Remove /etc/dhcpcd.duid and try again. If fails, please attach new failure.
Created attachment 170121 [details] 2nd not working 4.0 capture file I emerged 4.0.2, with compat use flag. The duid config option is in the dhcpd.conf. I deleted /etc/dhcpcd.duid, this file is recreated every time. Still not working. The capture file is attached.
Remove /etc/dhcpcd.conf, /etc/dhcpcd.duid and try again please.
Thanks! Now it's works. After I removed both it worked. Then I copied back the dhcpcd.conf (the original one, without duid) and it worked too.
