Can you outline the sequence of events from booting a machine, connection to the ISP, browser failure. This problem is with a plain old telephone modem on a PCI card -- right? You should be able to boot and not have the modem dial or connect. You should be able to connect to localhost. if apache is installed you will get the default page at http://localhost.localdomain We should inspect the output of: ifconfig netstat -r dig redhat.com cat /etc/resolv.conf cat /etc/hosts cat /etc/networks # should be absent just checking... locate ifcfg- hostname domainname cat /selinux/enforce grep SELINUX /etc/sysconfig/selinux Next you should dial and connect to the ISP. BE specific which tool you use and place the dial tool in debug/verbose mode if you can and report how you set it up. DHCP should assign an IP address and a name for that link. It is a good thing to place markers in the system logs thus: logger ReadyReadyReadyReadyReadyReadReady logger DialingDialingDialingDialingDialing logger ConnectingConnectingConnectingConnecting logger ConectEDConectEDConectEDConectEDConectED logger StartMozillaStartMozillaStartMozillaStartMozilla logger EndTestEndTestEndTestEndTestEndTest Share with the group all the /var/log/messages stuff from "Ready*" to "EndTest*" and prune all the other stuff out. ifconfig should change to show the connection netstat -r should show a new route via the modem. dig redhat.com resolv.conf should be updated. hostname should reflect the connection domainname might change. locate ifcfg- Do check the broadcast address and netmask. Some subnet stuff is easy to get wrong. When the broadcast address or net mask is broken lots of stuff can break. -- T o m M i t c h e l l /dev/null the ultimate in secure storage.
