After restarting the network service FreeBSD startet responding to the network... In above log i logged in to the system, ROOT LOGIN (root) ON ttyv1 and i can see same messages of kernel arp in my messages, means machine was on network (cause i have arp logs of the time when machine was not responding)..... Any idea? Thanks & Regards Anuj Singh
