RE: [squid-users] Re: Client can't connect but No log

If you bypass squid (turn off the squid, change your firewall to allow HTTP
through, and reconfigure and restart Internet explorer) maybe on one PC,
does the Internet work again?

I ask because I had the similar problems on my network with Windows XP.

It turns out that on my DHCP server, it was giving dead DNS server addresses
to clients (Windows gets its DNS information from the DHCP server). If you
have a Linux server look in /etc/resolv.conf, on a Windows server look in
Control Panel/Network. Then try to PING DNS server that's listed there. If
the ping dies, then the DNS server is dead.

Another way to test this is to take one Windows 98 client where the Internet
does not work.
Go into Control Panel, Network and assign a STATIC IP address (for example
192.168.1.180) and a STATIC DNS server, and your firewall server as the
gateway (may be 192.168.1.1). Now test out the Internet. Does it work? If it
works now, then you need to fix your DNS pointers on your server.

Good luck.

Thank for advice.
 Our user use windows98se and Internet Explorer 6.0 sp1.
 Because Company policy, We use win98se.
 After setting, IE and squid work good.
 After some hours or days, suddenly IE can't connect Internet via squid.
 Message is "Can't found page. DNS error or not found"
 squid is not transparent proxy.
 and set the crontab below

0 23 * * * /usr/local/squid/sbin/squid -k rotate
10 23 * * * /usr/local/sarg/sarg #use sarg for log report

Internet explorer does not require a DNS server to "internet"

Netscape, Mozilla, firebird, and firefox require a DNS server even if the
proxy settings are set.

Please specify which browser you are using and if the proxy settings are
correct.

Note : Internet explorer needs to be restarted for proxy settings to take
effect.
