Hej p� er,
h�r �r mitt problem:
box1 (openbsd 2.5) ip: 192.168.1.1 netmask 255.255.255.0
box2 (slackware 4.0) ip : 192.168.1.2 netmask 255.255.255.0
box1 fungerar perfekt men det g�r inte box2, jag har satt upp alla n�t.
kortet och det fungerar. men jag kan inte ansluta fr�n box2 --> box1
den svarar inte heller p� ICMP requests, det konstiga �r att om jag k�r
windows p� box2 s� kan jag ansluta till box1. Jag har redan tagit upp
detta p� en openbsd mailing lista, men eftersom problemet ligger p�
linux burken s� �r det nog b�ttre jag tar upp det h�r:
jag skickar med lite routeing tabeller och tcpdump m.m.
