Regards, Eric Are you using a proxy for Internet connection? Because, this kind of issues I've seen on it. 1- I think that you have to check your /etc/resolv.conf which are the entries that you have there. 2- The second advice that I give you is to analyze your network connection (rates, bandwidth, etc). You can use tcpdump - sar(included on the systat package http://pagesperso-orange.fr/sebastien.godard/) for all kind of statistics. For the network stats, you can use sar -n DEV | more - netstat: only focused on the network statistics a example: netstat --statistics --raw - traceroute: this is very useful for tracking down the cause of disappearing packages a example: traceroute host_name 3- You have to check the /etc/nsswitch.conf, which is the main responsible of the name resolution in Solaris and Linux. You will check too the nscd daemon I hope that's can help you On 07/04/2011 09:56 AM, Eric Tanguy wrote: > Since few days now i have a name resolution problem.
