Freeswan og x.509 certificate patch
Fra : Søren Emig


Dato : 01-03-02 20:56

Hej Linux folk!

Jeg er ved at rode med noget IPsec (freeswan) og x.509 certificate road
warrior VPN. Har downloadet den nyeste Freeswan, patchet med x.509, patchet
kernen og kompilreret det hele.

Problemet! Jeg forsøger at logge på med IPsec klienten (w2k), men der sker
ikke noget som helst. Har prøvet at sætte debug til all..... ingen ting
ekstra i loggen under forsøg på at kalde op. Havde ellers håbet på en fejl
eller noget i den stil.

Freeswan er ret nyt for mig....så en god ting er "ipsec barf". Jeg bliver
utrolig glad, hvis en erfaren linux/Ipsec/freewan admin kunne lede mig på
rette vej.

Her kommer det så ;)
