i have the following problem with ubuntu server 10.04:
from time to time the server drops the connection to the internet. i can ping and connect to others in the local network, but i can't ping external domains or make an apt update. the dns entries in resolv.conf are the right ones. another crazy thing is, if internet works and i start calendarserver (have removed it right now), the internet connection drops as well. when i restart it works again!
any advice? maybe some dns issue?
thanks in advance!
