Nemuzu prijit na to, na zaklade ceho se to stalo, protoze pro rozhrani eth2 pochopitelne nemam DHCP ani konfigurovane, ani pustene.

Povedlo se mi to potlacit editaci souboru /etc/dnmasq.conf, kde jsem pridal except-interface=eth2.

Nicmene radeji pokladam tento dotaz, cim vyresit pricinu a ne dusledek.

Zřejmě máte k eth2 připojené nějaké zařízení, co se dožaduje DHCP serveru.

eth2 je preci wan, ne?

Na Turrisu 1.0 a 1.1 je WAN na eth2, ale na Turris Omnia je WAN na eth1.

Vsak ja mam Turris v1.x :wink:

Tak nejspíš sdílíte WAN segment s nějakým zařízením, které marně hledá DHCP server. Není to nic, co by vás mělo znepokojovat, nejspíš to ani nejste schopen ovlivnit.

Takze pouze zakazat, jak jsem provedl pres except-interface=eth2 a dale neresit?

Ano, případně jen zprávy ignorovat.

A máte v /etc/config/dhcp sekci

config dhcp 'wan'
       option interface 'wan'
       option ignore '1'

já to tam po nějakém svém ručním hraní neměl a taky jsem zjistil, že se mi v logu toto vypisuje.

Praveze toto tam mam.
