[Ninux-Calabria] ptp brodo

[Giuseppe De Marco]

Ragazzi ieri Luca e Musk sono venuti a salutarci al CeSMMA e musk ne
ha approfittato per agganciare brodo al nuovo ptp

MA

i ragazzi di brodo mi hanno contattato per il tunnel rotto e ho
allineato il gateway a 172.17.87.5 ma niente. sia il 3 che il 5 mi
funzionano a l2 ma se


A l2 vedo cose che credo debbano essere un pò riordinate

ad esempio non mi aspetto di avere a l2 il 5 sia su eth1.7 che su
eth1.8, pare che abbiamo creato un link circolare (vedasi l2 lato
alfgenfeac).

meno un
root a Brodolini:~# ip -s -s neigh flush all

e ottengo
root a Brodolini:~# ip neigh show

ma se faccio arp -n sempre il 5 su eth1.8

e daje con
root a Brodolini:~# ip -s neigh del 172.17.87.5 dev eth1.8

va bene, mando già eth1.8 ed trovo i probes su eth1.5
172.17.87.5      0x1         0x0         00:00:00:00:00:00     *        eth1.5

mando giù anche eth1.5 e i probes vanno su eth0.9 !
Qui capisco che il kernel sta dando i numeri, prima di flushare tutto
e rischiare di brikarmi da remoto ho fatto il classico

reboot

e ripensando ai tempi del windows 98 vi saluto calorosamente
