The following tasks show how to check the status of the network by using well-known networking commands.
You can control the output of the netstat and ifconfig commands to display IPv4 information only, or both IPv4 and IPv6 information.
To display IPv4 information only:
DEFAULT_IP=IP_VERSION4
To display both IPv4 and IPv6 information:
DEFAULT_IP=BOTH
Or
DEFAULT_IP=IP_VERSION6
For more information about the inet_type file, see the inet_type(4) man page.
Note - The -4 and -6 flags in the ifconfig command override the values set in the inet_type file. The -f flag in the netstat command also overrides the values set in the inet_type file.
Example 8-14 Controlling Output to Select IPv4 and IPv6 Information
When you specify the DEFAULT_IP=BOTH or DEFAULT_IP=IP_VERSION6 variable in the inet_type file, you should have the following output:
% ifconfig -a lo0: flags=1000849 mtu 8232 index 1 inet 10.10.0.1 netmask ff000000 qfe0: flags=1000843 mtu 1500 index 2 inet 10.46.86.54 netmask ffffff00 broadcast 10.46.86.255 ether 8:0:20:56:a8 lo0: flags=2000849 mtu 8252 index 1 inet6 ::1/128 qfe0: flags=2000841 mtu 1500 index 2 ether 8:0:20:56:a8 inet6 fe80::a00:fe73:56a8/10 qfe0:1: flags=2080841 mtu 1500 index 2 inet6 2001:db8:3c4d:5:a00:fe73:56a8/64
When you specify the DEFAULT_IP=IP_VERSION4 variable in the inet_type file, you should have the following output:
% ifconfig -a lo0: flags=849 mtu 8232 inet 10.10.0.1 netmask ff000000 qfe0: flags=843 mtu 1500 inet 10.46.86.54 netmask ffffff00 broadcast 10.46.86.255 ether 8:0:20:56:a8
If you suspect a malfunction of routed, the IPv4 routing daemon, you can start a log that traces the daemon's activity. The log includes all packet transfers when you start the routed daemon.
The Primary Administrator role includes the Primary Administrator profile. To create the role and assign the role to a user, see Chapter 2, Working With the Solaris Management Console (Tasks), in System Administration Guide: Basic Administration.
# /usr/sbin/in.routed /var/log-file-name
![]() | Caution - On a busy network, this command can generate almost continuous output. |
Example 8-15 Network Log for the in.routed Daemon
The following example shows the beginning of the log that is created by the procedure How to Log Actions of the IPv4 Routing Daemon.
-- 2003/11/18 16:47:00.000000 -- Tracing actions started RCVBUF=61440 Add interface lo0 #1 127.0.0.1 -->127.0.0.1/32 <UP|LOOPBACK|RUNNING|MULTICAST|IPv4> <PASSIVE> Add interface hme0 #2 10.10.48.112 -->10.10.48.0/25 <UP|BROADCAST|RUNNING|MULTICAST|IPv4> turn on RIP Add 10.0.0.0 -->10.10.48.112 metric=0 hme0 <NET_SYN> Add 10.10.48.85/25 -->10.10.48.112 metric=0 hme0 <IF|NOPROP>
If you suspect a malfunction of the IPv6 in.ndpd daemon, you can start a log that traces the daemon's activity. This trace is displayed on the standard output until terminated. This trace includes all packet transfers when you start the in.ndpd daemon.
The Primary Administrator role includes the Primary Administrator profile. To create the role and assign the role to a user, see Chapter 2, Working With the Solaris Management Console (Tasks), in System Administration Guide: Basic Administration.
# /usr/lib/inet/in.ndpd -t
Example 8-16 Trace of the in.ndpd Daemon
The following output shows the beginning of a trace of in.ndpd.
