I had to modify the newtork configuration of a solaris 10 host. Below, some commands and files I used/needed. This post is mostly a reminder of bulk list of commands

• Mother of all network related command : ifconfig

• Display the routing table : netstat -nr

• Display open sockets, network connexions : lsof -i -n. This command is not inclueded in a standard installation, but can be obtained from solaris freeware.

• Add/Remove a permanent route : route -p

• Default route : cat /etc/defaultrouter

• Name resolution (aka DNS) :

  • Check /etc/resolv.conf for correct dns addresses.

  • Check that file /etc/nsswitch.conf contains a line with hosts: files dns

• Change an ip address :

  • Check the file /etc/hostname.interface for the hostname

  • Edit /etc/hosts and change the IP address

  • If the IP is subnetted with a weird netmask, add the wanted netmask to /etc/inet/netmasks

  • Restart the network by svcadm restart network/physical

• Configure network interfaces : dladm

  • Display interfaces : dladm show-dev

  • Display links : dladm show-links

  • Display aggregations : dladm show-aggreg

• Firewalling:
  • Status : ipfstatus

  • Display input/output rule set : ipfstatus -i or ipfstatus -o

  • Monitoring firewall in real time : ipmon

• IP Forwarding configuration : routeadm

• List/Configure network services based on inet: inetadm

• Capture and display network traffic : snoop

• Display/Modify network driver parameters : ndd

I had to migrate a running Solaris Zone (let's call it myZone) from host A to host B. The 2 hosts and the zone didn't have the same patches and packages. Making the zone running on host B was quite painfull. Follows how I did proceed (use it at your own risk).

• On the source host (host A) :

  1. Copy the zone filesystem (the zone path) to the host B. Copy the file /etc/zones/myZone.xml to the host B's /tmp folder.

• On the destination host (host B) :

  1. Attach the zone by issuing the command zoneadm attach -F -n /tmp/zoneName.xml 2>&1. This command will return packages and patches not matching the host B. Those lists are preceded by These packages installed on this system were not installed on the source system: for packages and These patches installed on this system were not installed on the source system: for patches.

  2. Add all the patches listed to the file /usr/lib/brand/native/bad_patches. After adding the pataches to the, reissuing the previous command should not complain about the missing pataches.

  3. Edit the file /etc/zones/index and add myZone:configured:zonePath: at the end of the file.

  4. Move the /tmp/zoneName.xml to /etc/zones/myZone.xml.

  5. Attach the zone using zoneadm -z myZone attach -u.

  6. Boot the by zoneadm -z zoneName boot. It should boot. If not, the config (network interface, mount points) should be adopted.
