Witam,
w koncu udalo mi sie znalesc w sieci jakies informacje + ksiazka i ruszylo,
podzialalo i przestalo, i tak sobie od rana snifuje, pakiety Hello wysylaja
od routery, jeden nawet reaguje zmiana Hello 44 na Hello 48.
Za nic nie moge dojsc o co chodzi, moze jest jakis soft do symulacji
routera w celu testowania ? Poki co wracam do ksiazki,
wszelkie pomysly bardzo mile widziane.
Pozdrawiam
PS przestalo po zmianie adresu IP nazwijmy to drugiego routera,
ale zmiany uwzglednilem w konfiguracji, moze quagga ma gdzies
pliki cache ktore cos mi utrudniaja ? nie wiem

iptables -A OUTPUT -o eth1 -j ACCEPT
iptables -A OUTPUT -o eth1 -p ospf -j ACCEPT
iptables -A OUTPUT -o eth1 -p igmp -j ACCEPT
iptables -A INPUT -p ospf -j ACCEPT -m state --state ESTABLISHED

moze cos jeszcze potrzeba ? np 0/1 do /proc/sys/net* ?
SOLVED
po drugie wystarczy mniej wpisow w iptables (dokladalem i dokladalem, sadzilem ze moze toto)
po trzecie (przy okazji) u mnie nie dziala najnowsza quagga tylko 0.98.6-r1
a po pierwsze, to MT (i niby specjalny/dedykowany na router  ), swinia nie stosuje
calej konfiguracji, z winbox, dostalem sie z konsoli, powklepywalem i ruszylo, obciach
Pozdrowienia

szczegol... moje gentoo (jak sadze to ono) wysyla jedna trase w eter, ktora jest
identyfikowana jako bledna przez inne routery, oto wypis z innego routerka:
| Code: |
# DST-ADDRESS PREF-SRC G GATEWAY DISTANCE INTERFACE

| Code: |
! osfp
hostname trinity

log file /var/log/quagga/ospf.log
!
interface eth1
ip ospf priority 254
ip ospf authentication-key oj

jeden wątek o ospf IMO wystarczy. Nie ma potrzeby zasypywania forum kolejnymi informacjami o ospf.
