Chapter 42 Working With Remote Systems (Overview)

This section includes information on working with remote files.

What Is the FTP Server?

The FTP Server is based on wu-ftpd. Originally developed by Washington University in Saint Louis, wu-ftpd is widely used for distribution of bulk data over the Internet and is the preferred standard for large FTP sites. For information on the licensing terms, refer to the materials that are incorporated at /var/sadm/pkg/SUNWftpu/install/copyright.

What Is a Remote System?

For the purpose of this chapter, a remote system is a workstation or server that is connected to the local system with any type of physical network and configured for TCP/IP communication.

On systems running the Solaris 9 release, TCP/IP configuration is established automatically during startup. For more information, see System Administration Guide: IP Services.

What's New for the Solaris 9 FTP Server?

The FTP Server is compatible with Solaris 8 FTP software, yet offers new capability with improved performance for Solaris 9 users.

Note –

The Solaris 8 /etc/default/ftpd is not supported in the Solaris 9 release. During upgrade, BANNER and UMASK entries are converted to their wu-ftpd equivalents. However, the system administrator might need to manually convert some BANNER lines for the equivalent ftpaccess greeting capability. For further information, see ftpaccess(4).

Note –

The sublogin feature that is provided by the Solaris 8 FTP Server is not supported by the Solaris 9 FTP Server.
