Installation guide

• CD-ROM (compact disc read-only memory) File System (CDFS)
Conforms to the ISO 9660 standard. See cdfs
(4) for more information.
• Virtual File System (VFS) interface and framework
The VFS interface enables transparent access to UFS and NFS file
systems and allows both file systems to run in parallel. Transparent
access is accomplished by retaining the traditional operating system
interfaces on top of the VFS layer. Therefore, the file system types are
not apparent to the user.
• The /proc File System
A debugging file system that is compatible with the System V, Release 4
specification. This file system is a development tool that allows any
process to control and monitor the execution of another unrelated
process. See proc
(4) for more information.
You set up, check, and maintain DIGITAL UNIX file systems in much the
same way that you perform these tasks on ULTRIX systems. For
information about administering file systems, see Section 4.8.
1.2.4 System and Network Administration Tools
System and network administration tasks on a DIGITAL UNIX system are
comparable to those on an ULTRIX system.
You can set up your system so that users can print files on local and remote
printers. Users can also print PostScript files on local or remote PostScript
printers. The remote printing occurs over a Transmission Control
Protocol/Internet Protocol (TCP/IP) network.
The DIGITAL UNIX system includes TCP/IP for use on a local area
network (LAN) or wide area network (WAN). You manage the network
components by using many of the same commands that you use on an
ULTRIX system, such as the arp, ifconfig, and hostid commands. The
system also includes the Simple Network Management Protocol (SNMP)
Agent, which gives information to an SNMP network management station.
The DIGITAL UNIX system includes many of the distributed system
services available on ULTRIX. In particular, it includes the Berkeley
Internet Name Domain (BIND) service and the Network Information
Service (NIS, formerly called YP). For time synchronization, the DIGITAL
UNIX system includes the Network Time Protocol (NTP).
Like the ULTRIX system, the DIGITAL UNIX system uses the sendmail
utility as the general-purpose internet mail router. The system also
includes the uucp utility. You can use uucp to copy files between UNIX
systems and to execute commands on remote UNIX systems.
