Resolve gz to ip address (from /etc/hosts file):

#host gz

To change the host name to gz:

#hostname gz

To the status of ethernet device en0:

#entstat en0

To list the detailed status of device en0:

#entstat -d en0

To list all net configurable attributes and their values:

#no -a

To change gzwall parameter to its default value:

#no -d gzwall

To make the machine as router in tcpip networks:

#no -o ipforwarding=1

To trace the route to gz:

#traceroute gz

To tcp ping to the machine gz:

#ping gz

To show the status of all network interfaces:

#ifconfig -a

To show the status of en0:

#ifconfig en0

Turns on network card en0:

#ifconfig en0 up

Turns off network card en0:

#ifconfig en0 down

Removes en0 card from the network interface list:

#ifconfig en0 detach

Configure en0 starts immediately:

Temporarily:# ifconfig en0 inet netmask up
Permanently:# chdev -l en0 -a netaddr= -a netmask=0xffffff00

Create alias ip address for en0:

Temporarily:# ifconfig en0 alias netmask
Permanently:# chdev -l en0 -a alias4=,

Remove a permanently added alias:

# chdev -l en0 -a delalias4=,
Via SMIT: # smitty tcpip -> further Configuration -> Network Interfaces -> Network Interface Selection -> Configure Aliases

To make as default gateway for entire network:

Temporarily:#route add 0
Permanently:#chdev -l inet0 -a route=0,

To remove a route:

Temporarily:#route del 0
Permanently:#chdev -l inet0 -a delroute=0,

To make 200.7 as gateway for 300.0 network:

#route add 192.100.300.0

To clear the gateway table:

#route -f

To change the host name to gz permanently:

#chdev -l inet0 -a hostname=gz

To set the MTU to 1500 on en69:

#chdev -l en69 -a mtu=1500

To show the state of all sockets:

#netstat -a

To show the network buffers cache:

#netstat -c

To show the net drops of packets:

#netstat -D

To display interface statistics:

#netstat -i

To show the routing table:

#netstat -r

To show routing table (ip will be given instead of host names)

#netstat -rn

To show the statistics of the protocols

#netstat -s

To show the statistics of respective protocols

#netstat -s -p < tcp/udp/ipv6>
