# The netmasks file associates Internet Protocol (IP) address
# masks with IP network numbers.
#
# network-number netmask
#
# The term network-number refers to a number obtained from the Internet Network
# Information Center
#
# Both the network-number and the netmasks are specified in
# "decimal dot" notation, e.g:
#
# 128.32.0.0 255.255.255.0
#
3.158.24.0 255.255.252.0

# The networks file associates Internet Protocol (IP) network numbers
# with network names. The format of this file is:

Commands
Ifconfig – can configure all network interface operations
Ifconfig –a – status of all network interfaces; lo0 is loopback address
lo0: flags=2001000849<UP,LOOPBACK,RUNNING,MULTICAST,IPv4,VIRTUAL> mtu 8232 index 1
inet 127.0.0.1 netmask ff000000
eri0: flags=1000843<UP,BROADCAST,RUNNING,MULTICAST,IPv4> mtu 1500 index 2
inet 3.120.191.100 netmask fffffc00 broadcast 3.120.91.255
eri0:1: flags=1000842<BROADCAST,RUNNING,MULTICAST,IPv4> mtu 1500 index 2
inet 0.0.0.0 netmask 0
Ifconfig eri0 down - disable the interface
Ifconfig eri0 up - enable the interface
Ifconfig eri0 3.58.24.55 up – set IP address and enable the interface
Ifconfig eri0 netmask 255.255.252.0 broadcast + up - set netmask and broadcast value
Ifconfig eri0 broadcast + up - set broadcast based on netmask
Ifconfig eri0 unplumb – close the interface
Ifconfig eri0 plumb - opens the interface
Ifconfig eri0 recb0001 netmask+broadcast+up
ifconfig hme0 ip-addr netmask 255.255.255.0 broadcast + up
You can combine two commands in one shot
Ifconfig eri0 down && ifconfig -a
Down an interface and show the status
Ifconfig eri0 router – Enable IP forwarding
Ifconfig eri0 –router - Disable IP forwarding
Ifconfig eri0 broadcase + reset broadcast address
hostname
DR0001
ping <hostname>
is alive should come
Conditions:
- The interface must be plumbed, which is automatically carried during boot by /lib/svc/method/net-physical script
2. The interface must be configured
3. The interface must be up
4. The interface must be physically connected
5. The interface must have valid routes configured
Steps to change IP address in Solaris 10
- edit /etc/hosts file
- edit /etc/inet/ipnodes
- edit /etc/netmasks
- edit /etc/defaultrouter if set in a new location
- restart the network/physical service
svcadm restart network/physical
Steps to create virtual IP in Solaris
1. create /etc/hostname.eri0:1 or hostname:hme0:1 file with hostname of Server
2. edit /etc/hosts with IP address and hostname
3. plumb the new Interface
ifconfig eri0:1 plumb
up the interface with IP address and netmask
ifconfig eri0:1 3.158.24.55 netmask 255.255.252.0 broadcast + up
