Ping Failure on DNS lookup

Remember that ping often uses gethostbyname system/kernel call where traceroute often uses the actual DNS lookup. You can also easily test whether the entries are indeed in DNS by using nslookup or dig

NAME
vmxnet - vmware kernel module SYNOPSIS
modprobe vmxnet DESCRIPTION
This is a Linux kernel device driver module that drives VMware's fast networking device. As it is backed by real (virtual) hardware, it should be automatically loaded by hotplug or udev as needed. For best performance, it is recommended to enable TSO on all interfaces driven by vmxnet using ethtool. The shell code to do this might look like this: if which ethtool >/dev/null 2>&1; then for ethif in `ifconfig -a | grep ^eth | cut -d' ' -f1`; do ethtool -K $ethif tso on >/dev/null 2>&1 done fi The VMware backend may present the fast networking device as an AMD vlance device instead of the actual vmxnet device.
