Switch to manual configuration

To disable automatic procedures to take back your changes you have to enable the manual configuration mode.

# netadm enable –p ncp defaultfixed

Nodename

# svccfg -s svc:/system/identity:node setprop config/nodename = astring: camponotus
# svcadm refresh svc:/system/identity:node
# svcadm restart svc:/system/identity:node

Initial setup

# ipadm create-ip net1 
# ipadm create-addr -T static -a local=192.168.5.101/24 net1/v4mailcluster1

Set one interface to standby:

# ipadm set-ifprop -p standby=on -m ip net2
# ipmpstat -i
INTERFACE   ACTIVE  GROUP       FLAGS     LINK      PROBE     STATE
net3        yes     ipmp0       --mbM--   up        ok        ok
net2        no      ipmp0       is-----   up        ok        ok
# ipmpstat -g
GROUP       GROUPNAME   STATE     FDT       INTERFACES
ipmp0       ipmp0       ok        10.00s    net3 (net2)

Change address

1. Create new interface:

# ipadm create-addr -T static -a 192.168.5.111/24 ipmp0/v4mailcluster1

2. Login to new IP.

3. Delete the old interface:

# ipadm delete-addr ipmp0/v4mailcluster0

DNS

Client

# svccfg -s svc:/network/dns/client setprop config/nameserver = net_address: "( 0.0.0.0 192.168.1.1 )"
# svccfg -s svc:/network/dns/client setprop config/search = astring: "timmann.de blindhuhn.de"
# svcadm refresh svc:/network/dns/client:default
# svcadm restart svc:/network/dns/client:default

Activate dns in nameservice switch (nsswitch.conf):

# perl -pi -e "s/^hosts:\s+files$/hosts: files dns/g" /etc/nsswitch.conf
# nscfg import -f svc:/system/name-service/switch:default
# svcadm refresh name-service/switch
# svcprop -p config/host svc:/system/name-service/switch:default
files\ dns

Server

# groupadd -g 53 dns
# useradd -u 53 -g dns -d /var/named -m dns
# usermod -A solaris.smf.manage.bind dns
# svccfg -s svc:network/dns/server:default setprop start/group = dns
# svccfg -s svc:network/dns/server:default setprop start/user  = dns
# svccfg -s svc:network/dns/server:default setprop options/ip_interfaces = IPv4
# svccfg -s svc:network/dns/server:default setprop options/configuration_file = /etc/named.conf
# svcadm refresh svc:network/dns/server:default
# svcadm enable  svc:network/dns/server:default

Set tcp/udp parameter (formerly ndd)

# ipadm show-prop -p smallest_anon_port tcp
PROTO PROPERTY            PERM CURRENT      PERSISTENT   DEFAULT      POSSIBLE
tcp   smallest_anon_port  rw   1024         --           1024         1024-65535

# ipadm set-prop -p smallest_anon_port=9000 tcp
# ipadm set-prop -p smallest_anon_port=9000 udp
# ipadm set-prop -p largest_anon_port=65500 tcp
# ipadm set-prop -p largest_anon_port=65500 udp

Jumbo Frames

The MTU of an ipadm-interface can never be greater than its underlying dladm-interface. To change the dladm-interface the ipadm-interface has to be disabled (DOWNTIME!? BE CAREFUL!).

# ipadm disable-if -t iscsi0
# dladm set-linkprop -p mtu=9000  iscsi0
# ipadm enable-if -t iscsi0
# ipadm set-ifprop -m ipv4 -p mtu=9000 iscsi0
