Megoldva! Ubuntu 22.04-re frissítés után két 22.04 között: no route to host. Wan, más local gépek elérhetők.

Hálózatok általános

Kedves Hozzáértők!

Ubuntu 22.04-re frissítés után két 22.04 között nincs kapcsolat: no route to host.

A 192.168.23.100-ról szeretném elérni a 192.168.23.101-t.

Wan, más local gépek elérhetők.

Tűzfal kikapcsolva.

Mindkét gépen van LXD, Docker, az egyiken KVM is.

Tanácsot kérek!

 

Machine-ID és br0 macaddress változtatása megoldotta.

Mire megyünk a megváltoztatott IP-címekkel?

Azt írtál be, amit sikerült, hozhattál be új hibát, elfedhetted az igazit.

Ez valami paranolya?

Esetleg egy legacy ifonfig kimemete? Az a 'linkdown' engem valamiért az 'offline'-ra emlékeztet.

Én olyat tapasztaltam, hogy egy(!) internetes hostra connection refused jött. Akármit csináltam (suspend, wlan off-on), nem tudtam elérni.

tcpdumppal nézve a WLAN IF-et nem látszott a forgalom, loopback IF-en nem szerepelt ez az IP. Csomagszűrőszabályokról szintén nem tudok, működött, aztán egyszercsak nem. WTF?

Nem jött létre valami hibrid rendszer a systemd által kezelt és a NetwokManager által kezelt hálózati rendszerekből és az kutyul meg valamit?

jo lett volna latni mindket gep adatait, nem csak az egyik oldalt. ezert most csak tippelek egyet:

a br0 MAC cime nem lett veletlenul ugyanaz a 2 gep eseten? nemregiben valtoztattak es az ujabb linuxokban a br0 mar nem az egyik member fizikai port mac cimet orokli (mint regen), hanem valahogy a systemd general neki egy cimet valamibol perzisztensen.

"systemd-networkd assigns a MAC address generated based on the interface name and the machine ID to the bridge."

https://man.archlinux.org/man/machine-id.5

amikor szivtam hasonloval a google csomo talalatot hozott erre hogy foleg klonozott gepek eseten ugyanaz lett a bridge cime, hiaba ter el a fizikai mac cimuk.
