Losing access to websites?
« on: September 18, 2010, 07:48:51 PM »
Over the last couple of days we are progressively lossing access to certain websites. The issue may have started with the lastest update.
 
When I access http://www.newegg.com the bowser times out with:
 
•Internet connectivity has been lost.
•The website is temporarily unavailable.
•The Domain Name Server (DNS) is not reachable.
•The Domain Name Server (DNS) does not have a listing for the website's domain.
•There might be a typing error in the address.
 
The list of unaccessible websites is growing with time.
 
If I connect to the network exteral to SME it works fine. The SME server is configured with a dedicated static IP and no specific DNS server was entered.
 
The issue is there whether or not squid is enabled.
 
 
Here are the logs:
 
code:
 
echo "" > /var/log/messages
sv d /service/squid
sleep 35
echo "" > /var/spool/squid/swap.state
sv u /service/squid

That's a silly thing to do. You just lost the content of your messages logfile. Why did you do that?

Yes .... what I did not show you was that I copied it first. I just wanted a "clean" log.

There are easier ways to read the more recent part of a long file, for instance using tail.

You will have lost any log messages which were created in the time between your copying of the log file and you emptying the log.
