Domácí síť. Na Gentoo mi dhcpcd verze 3 funguje bez problémů, ale verze 4 ne. Adresu dostane a vypíše, ale nenastaví:

anaconda linux-2.6.23-gentoo-r8 # dhcpcd eth0 -d
eth0: dhcpcd 4.0.2 starting

Takhle vypadá výpis z tcpdumpu:

V manuálu se mi nepovedlo o tomhle najít ani zmínku, tedy ani návod, jak to vypnout. Nakonec jsem provedl downgrade na verzi 3. Bugzilla pro dhcpcd nefunguje. Netušíte někdo, v čem je problém?

Napada me snad jen porovnat pakety detailne ve Wiresharku. Musi tam byt nejaky rozdil.
