ok, this is really pissing me off

I have one ubuntu 8.04 instance running on vmware (esx) which decided after a reboot to stop resolving dns requests, I also cant connect to it using ssh although I can ping the server and its really that server (when I shutdown the server the ping also stops)

stuff I tried: - reboot again :) - nslookup - serverip - setting networking to dhcp - offering some cute kittens to lucifer - removing the virtual nic and adding another (to get a different mac) - migrating the instance to another esx host - drinking 20 cups of espresso - stopped all services - running dnsmasq on another server and connecting to that dns - tcpdumping - disabling ip6

symptoms:

  • cant resolve anything
  • nslookup just says "no servers found..." although I can ping the servers
  • traceroute to gateway doesnt work (even with traceroute -4 -n gatewayip)
  • collegues laughing at me

any thoughts
