Basic Networking
/etc/services
Many inetd services must be mapped to a specific port number: a sample /etc/services file, shown next, defines port numbers for most of the commonly used services:
tcpmux echo echo discard discard systat daytime daytime netstat 1/tcp 7/tcp 7/udp 9/tcp 9/udp 11/tcp 13/tcp 13/udp 15/tcp
sink null sink null users
Checking if a Host Is Up
The easiest way to check if a remote host is accessible is to use the ping command. The following example checks whether the host emu is accessible from the host dingo:
$ ping emu
If emu is accessible, the following output will be generated:
emu is alive
However, if emu is not accessible, an error message similar to the following will be seen:
Request timed out
If you need to determine at what point in the network the connection is failing, you can use the traceroute command to display the path taken by packets between the two hosts as they travel across the network. For example, to observe the route of the path taken by packets from AT&T to Sun s Web server, I would use the following command:
$ traceroute www.sun.com Tracing route to wwwwseast.usec.sun.com [192.9.49.30] over a maximum of 30 hops: 1 184 ms 142 ms 138 ms 202.10.4.131 2 147 ms 144 ms 138 ms 202.10.4.129 3 150 ms 142 ms 144 ms 202.10.1.73 4 150 ms 144 ms 141 ms atm11-0-0-11.ia4.optus.net.au [202.139.32.17] 5 148 ms 143 ms 139 ms 202.139.1.197 6 490 ms 489 ms 474 ms hssi9-0-0.sf1.optus.net.au [192.65.89.246]

If the connection was broken at any point, then * or ! would be displayed in place of the average connection times displayed. An asterisk would also appear if the router concerned was blocking connections for traceroute packets.
Command Reference
The following commands are useful for configuring Solaris networking.
You can check the table of IP address to MAC address mappings by using the arp command:
$ arp a Net to Media Table Device IP Address ------ ---------------------hme0 www.cassowary.net hme0 mail.cassowary.net hme0 ftp.cassowary.net hme0 BASE-ADDRESS.MCAST.NET
Mask Flags Phys Addr --------------- ----- --------------255.255.255.255 00:19:cd:e3:05:a3 255.255.255.255 08:11:92:a4:12:ee 255.255.255.255 SP 08:12:4e:4d:55:a2 240.0.0.0 SM 01:01:4e:00:00:00
Here, the network device is shown with the fully qualified hostname (or IP address), the netmask, any flags, and the MAC address. The flags indicate the status of each interface, including SP for the localhost, where an entry will be published on request, and SM for the localhost, supporting multicast. Alternatively, a specific host can be queried by passing its name on the command line:
