The following commands are useful for checking your network configuration and activity.
To view the ARP table, enter the following command:
# arp -a
jetsam.v.com (111.0.110.151) at 00:00:0C:07:AC:00 [ether] on eth0
cds17-m1.v.com (111.0.210.170) at 00:30:48:58:5B:A1 [ether] on eth0
cds17-v1.v.com (111.0.210.171) at 00:30:48:31:53:B2 [ether] on eth0
? (111.0.210.175) at 00:30:48:32:0A:5A [ether] on eth0
cds17-s1.v.com (111.0.210.172) at 00:04:23:D8:89:44 [ether] on eth0
cds17-s1.v.com (111.0.210.172) at 00:04:23:D8:89:44 [ether] on eth0
To view the IP routing table, enter the following command:
# netstat -rn
Kernel IP routing table
Destination Gateway Genmask Flags MSS Window irtt Iface
111.0.210.0 0.0.0.0 255.255.255.0 U 0 0 0 eth0

To view the CDS subnet table, enter the following command:
# cat /arroyo/test/SubnetTable
network 111.1.13.1 netmask 255.255.255.240 gateway 111.1.13.1 transport_source_ip 0
Note The local networks and their gateways are specified in the SubnetTable file. For backward compatibility,
the local subnet and gateway in the RoutingTable are still supported and are used if the SubnetTable file
does not exist. The Routing Table can still be used to specify static routes.
To view the CDS routing table, enter the following command:
# cat /arroyo/test/RoutingTable
default gateway 111.1.13.1
network 111.1.13.1 netmask 255.255.255.240 gateway 0.0.0.0
To view the CDS remote server table, enter the following command:
# cat /arroyo/test/RemoteServers
