[AC] client vtun

[Sławomir Sędyka]

Próbuję zestawić tunel i klient mi nie działa.
(Raz jeden udało mi się uruchomić wczoraj, ale sytuacja już się nie 
powtórzyła)

Serwer działa.
W akcie desperacji nawet odwróciłem role komputerów i sytacja dalej taka 
sama: server działa, client - nie.

Oto client:

# rpm -q dev vtun
dev-2.9.0-8
vtun-2.6-2

w logach ląduje taki błąd:
