How to Perform Basic Network Software Checking

1. On the local system, assume the Network Management role or become superuser.

   Roles contain authorizations and privileged commands. For more information about roles, see Configuring RBAC (Task Map) in System Administration Guide: Security Services.

2. Use the netstat command to display network information.

   For syntax and information about the netstat command, refer to Monitoring Network Status With the netstat Command and the netstat(1M) man page.

3. Check the hosts database to ensure that the entries are correct and current.

   For information about the /etc/inet/hosts database, refer to hosts Database and the hosts(4) man page.

4. If you are running the Reverse Address Resolution Protocol (RARP), check the Ethernet addresses in the ethers database to ensure that the entries are correct and current.

5. Try to connect to the local host by using the telnet command.

   For syntax and information about telnet, refer to the telnet(1) man page.

6. Ensure that the network daemon inetd is running.

   # ps -ef | grep inetd

   The following output verifies that the inetd daemon is running:

   root 57 1 0 Apr 04 ? 3:19 /usr/sbin/inetd -s

7. If IPv6 is enabled on your network, verify that the IPv6 daemon in.ndpd is running:

   # ps -ef | grep in.ndpd

   The following output verifies that the in.ndpd daemon is running:

   root 123 1 0 Oct 27 ? 0:03 /usr/lib/inet/in.ndpd
