Adding a Specific Logical Interface with the Solaris 10

By Julien Gabel on Tuesday 13 March 2007, 19:21 - Solaris

Under Solaris 10, there is no /etc/init.d/inetsvc network script anymore. You must use the new SMF to manage your network services, even special initialization ones. In order to plumb and up a new logical interface, you can now use the service instance named svc:/network/physical:default.

Here is quick example on how to use it:

# ifconfig -au4
lo0: flags=2001000849<UP,LOOPBACK,RUNNING,MULTICAST,IPv4,VIRTUAL> mtu 8232 index 1
        inet 127.0.0.1 netmask ff000000 
nge0: flags=201004843<UP,BROADCAST,RUNNING,MULTICAST,DHCP,IPv4,CoS> mtu 1500 index 2
        inet 192.168.1.101 netmask ffffff00 broadcast 192.168.1.255
        ether 0:e0:81:58:88:ae 
# 
# cat /etc/hostname.nge0:1
192.168.1.50
# 
# svcadm restart network/physical
#
# ifconfig -au4
lo0: flags=2001000849<UP,LOOPBACK,RUNNING,MULTICAST,IPv4,VIRTUAL> mtu 8232 index 1
        inet 127.0.0.1 netmask ff000000 
nge0: flags=201004843<UP,BROADCAST,RUNNING,MULTICAST,DHCP,IPv4,CoS> mtu 1500 index 2
        inet 192.168.1.101 netmask ffffff00 broadcast 192.168.1.255
        ether 0:e0:81:58:88:ae 
nge0:1: flags=201000843<UP,BROADCAST,RUNNING,MULTICAST,IPv4,CoS> mtu 1500 index 2
        inet 192.168.1.50 netmask ffffff00 broadcast 192.168.1.255
# 
# ifconfig nge0:1 down unplumb
#
# ifconfig -a4
lo0: flags=2001000849<UP,LOOPBACK,RUNNING,MULTICAST,IPv4,VIRTUAL> mtu 8232 index 1
        inet 127.0.0.1 netmask ff000000 
nge0: flags=201004843<UP,BROADCAST,RUNNING,MULTICAST,DHCP,IPv4,CoS> mtu 1500 index 2
        inet 192.168.1.101 netmask ffffff00 broadcast 192.168.1.255
        ether 0:e0:81:58:88:ae

Remote X11 Display Using the Secure By Default Network Profile

By Julien Gabel on Tuesday 2 January 2007, 22:43 - Solaris

Although already present for months in the Sun's OpenSolaris distribution, the new Secure By Default Network Profile feature is now available with the 11/06 update of the official Solaris release.

If you didn't get it through a fresh install, you can turn it on using the provided shell script (as /usr/sbin/netservices). It all works well, except in our case (at work) we want to be able to do remote display on X11. So, we use this quickly-written script in order to be able to do so easily:

# cat /tmp/svc.netservices
#!/usr/bin/env sh

echo "Setting the limited SMF configuration..."
netservices limited

echo "Setting the open form of x11-server..."
svccfg -s x11-server setprop options/tcp_listen = boolean: true

echo "Setting the open form of cde-login..."
svccfg -s cde-login setprop dtlogin/args = "\"\""
echo "Refresh the cde-login SMF service..."
svcadm refresh cde-login

echo "Restarting the SMF services..."
svcadm restart cde-login

exit 0

Hope this help... at least, it will be an online-memo for us!
