<para>At times, users see a few <quote>watchdog timeout</quote> errors.
The first thing to do here is to check your network cable. Many cards require
a PCI slot which supports the Bus Mastering. On some old motherboards, only
one PCI slot allows it (most of time slot 0). Check the network card and
a PCI slot which supports Bus Mastering. On some old motherboards, only
one PCI slot allows it (usually slot 0). Check the network card and
the motherboard documentation to determine if that may be the problem.</para>
<para>No route to host messages occur if the network is either not set up
properly, or if the cable is not plugged in. Its rare when this is the
cards fault.</para>
<para><quote>No route to host</quote> messages occur if the
system is unable to route a packet to the destination host.
This can happen if no default route is specified, or if a
cable is unplugged. Check the output of <command>netstat
-rn</command> and make sure there is a valid route to the host
you are trying to reach. If there is not, read on to <xref

<para>If you see a <quote>ping: sendto: Permission denied</quote> error,
then its possible your firewall is misconfigured. Read the firewalls

<para><quote>ping: sendto: Permission denied</quote> error
messages are often caused by a misconfigured firewall. If
<command>ipfw</command> is enabled in the kernel but no rules
have been defined, then the default policy is to deny all
traffic, even ping requests! Read on to <xref
