inetadm p
Note - The Internet daemon inetd provides services for many network protocols, including the Telnet and File Transfer Protocol FTP protocols. You can enable the trace option for each inetd-managed service to send messages to the syslogd daemon. Use the inetadm command to modify the settings of the service to enable TCP tracing. When you enable the trace option, it uses the daemon.notice to log the client's IP address and TCP port number, and the name of the service. To enable tracing TCP...
The swapfs File System
When the kernel runs a process, swap space for any private data or stack space for the process must be reserved. The reservation occurs in case the stack information or private data might need to be paged out of physical memory, for example, if there are multiple processes contending for limited memory space. Because of the virtual swap space provided by the swapfs file system in the Solaris 10 OS, there is less need for physical swap space on systems with a large available memory. The...
Configuring the DNS Client During Installation
During the system identification phase of a Solaris 10 OS installation, you use several windows to configure the name service. You use function keys or the Escape key to continue through the different windows, depending on the type of installation. For this demonstration, the Escape keys are used. Note - Text in these screens has been edited for readability, and to fit on the page. To configure the system to use DNS, complete the following steps 1. In the Name Service window, select DNS as the...
Starting RPC Services on Demand
Some rpcbind services start only on demand. The port numbers are registered with the rpcbind process during boot. Figure 2-7 shows the steps involved in requesting an RPC port address. When a client application requests a service, the rpcbind process returns the port number of the service to the client machine. The client machine generates a new request using the port number that it just received for the requested service. spray 1 rpc.sprayd rpc.sprayd portnnnnn spray 1 rpc.sprayd rpc.sprayd...
Constructing the sysidcfg File
The sysidcfg file lets you specify many different identification items. Entries in the sysidcfg file must conform to the following rules Independent keywords can be listed in any order. Keywords are not case sensitive. Keyword values can be optionally enclosed in single ' or double quotation marks. Dependent keyword values must be enclosed in curly braces to tie them to their associated independent keyword. Only the first instance of a keyword is valid. If a keyword is specified more than once,...

Swap Slices
The primary swap space on the system is a disk slice. In the Solaris 10 OS, the default location for the primary swap space is slice 1 of the boot disk, which by default, starts at cylinder 0. You can change the default location during a custom installation. Each time you reboot the system, an entry in the etc vfstab file determines the configuration of the swap partition. As additional swap space becomes necessary, you can configure additional swap slices. Plan your swap slice location...
The mountd Daemon
The mountd daemon handles NFS file system mount requests from remote systems and provides access control. The mountd daemon checks the etc dfs sharetab file to determine whether a particular file or directory is being shared and whether the requesting client has permission to access the shared resource. When an NFS client issues an NFS mount request, the mount command on the client contacts the mountd daemon on the server. The mountd daemon provides a file handle to the client.File handles are...
