I've had a /29 provisioned on a network port for a server and am trying to at least configure the machine so I can ssh into it. It's Centos 6.2 x64 with the Basic Server install. Currently not able to ping gateway or any address for that matter.

For reference:

Default Interface: em2
Network ID: 66.*.*.0/29
Gateway: 66.*.*.1
Broadcast: 66.*.*.7

Please see my following configs:

/etc/sysconfig/network-scripts/ifcfg-em2

DEVICE=em2
NM_CONTROLLED=yes
ONBOOT=yes
HWADDR=Not Important
TYPE=Ethernet
BOOTPROTO=none
IPADDR=66.*.*.2
PREFIX=29
DNS1=8.8.8.8
DNS2=8.8.4.4
DEFROUTE=yes
IPV4_FAILURE_FATAL=yes
IPV6INIT=no
NAME="System em2"
NETMASK=255.255.255.248
USERCTL=no

$: route -n
Destination // Gateway // Genmask // Flags // Metric // Ref // Use // Iface
66.*.*.0       0.0.0.0    255.255.255.248   U   0   0     0  em2
169.254.0.0    0.0.0.0    255.255.0.0       U   0   1003  0  em2
0.0.0.0        66.*.*.1   0.0.0.0           UG  0   0     0  em2

$: route
Destination // Gateway // Genmask // Flags // Metric // Ref // Use // Iface
66.*.*.0       *          255.255.255.248   U   0   0     0  em2
link-local     *          255.255.0.0       U   0   1003  0  em2
default        66.*.*.1   0.0.0.0           UG  0   0     0  em2

$: cat /etc/sysconfig/network
NETWORKING=yes
HOSTNAME=excalibur.domain.com
GATEWAY=66.*.*.1

Keep in mind that I cannot even currently ping the gateway which is quite confusing for me. My /etc/hosts are configured correctly with the *.2 address. I'm not concerned with getting all of the addresses on the /29 up and running yet, just one so I can at least ssh in.

Thanks!

Edit: Adding in ifconfig.

$: ifconfig
