/etc

The /etc directory contains host-specific system files and programs used for administration and configuration.

These files include:

/etc/acl.conf
Specifies permitted operations on a defined SNMP context. See /etc/acl.conf in the Utilities Reference.
/etc/autoconnect
Automatic TCP/IP connection-configuration script. See /etc/autoconnect in the Utilities Reference.
/etc/bootptab
Network boot protocol server configuration file. See /etc/bootptab in the Utilities Reference.
/etc/config/
A directory that contains system-configuration files, such as the ttys file that tinit uses to configure terminal devices.
/etc/context.conf
Context definitions for SNMP v2. See /etc/context.conf in the Utilities Reference.
/etc/default/
A directory that contains default configuration files, primarily for TCP/IP facilities.
/etc/dhcpd.conf
Dynamic Host Configuration Protocol configuration; see /etc/dhcpd.conf in the Utilities Reference.
/etc/ftpd.conf
Specifies configuration options for ftpd that apply once you've authenticated your connection. See ../../com.qnx.doc.neutrino.utilities/topic/f/ftpd.conf.html in the Utilities Reference.
/etc/ftpusers
Defines users who may access the machine via the File Transfer Protocol. See /etc/ftpusers in the Utilities Reference.
/etc/group
User account group definitions; see Managing User Accounts.
/etc/hosts
Network hostname lookup database; see also /etc/nsswitch.conf and /etc/resolv.conf, below. See /etc/hosts in the Utilities Reference.
/etc/inetd.conf
Internet super-server configuration file that defines Internet services that inetd starts and stops dynamically as needed.
Note: The descriptions in the default version of this file are commented out; uncomment the ones that you want to use. See /etc/inetd.conf in the Utilities Reference.
/etc/mib.txt
Defines the format for specifying variable names for SNMP utilities; see /etc/mib.txt in the Utilities Reference.
/etc/motd
Contains an ASCII message of the day that may be displayed when users log in, as long as /etc/profile is configured to display it.

The default /etc/profile displays this file only if the /etc/motd file is more recent than the time you last logged in to the system, as determined by the time your $HOME/.lastlogin file was last modified. For more information, see the description of /etc/profile in Configuring Your Environment.

/etc/networks
Network name database file. For more information, see /etc/networks in the Utilities Reference.
/etc/nsswitch.conf
Name-service switch configuration file. For more information, see /etc/nsswitch.conf in the Utilities Reference.
/etc/opasswd
Backup of /etc/passwd file before its last change via the passwd utility. See the Managing User Accounts chapter.
/etc/oshadow
Backup of /etc/shadow file before its last change via the passwd utility. See Managing User Accounts.
/etc/party.conf
Configuration file for SNMP v2 party definitions. See /etc/party.conf in the Utilities Reference for more details.
/etc/passwd
This file defines login accounts. See the chapter Logging In, Logging Out, and Shutting Down, as well as Managing User Accounts for more details; also see passwd, login in the Utilities Reference.
/etc/profile
The startup profile script executed by the shell when you log in; it's executed before $HOME/.profile. See Configuring Your Environment.
/etc/profile.d/
A directory where the default /etc/profile script looks for scripts to run when any user logs in. The /etc/profile script runs each script in this directory that matches *.$(SHELL##*/}. For example, if the value of the SHELL environment variable is /bin/sh, the script runs the scripts that match *.sh.
/etc/rc.d/
A directory where you usually keep local system-initialization files. For more information, see the description of /etc/system/sysinit in Controlling How Neutrino Starts.
/etc/resolv.conf
Resolver configuration file; see also /etc/hosts, above. See /etc/resolv.conf in the Utilities Reference.
/etc/skel/
A directory that holds the default version of .profile. When you add a new user to the system, this file is copied to the user's home directory. For more information, see the description of /etc/default/passwd in the documentation for passwd, and the description of .profile in Configuring Your Environment.
/etc/system/
A directory that includes files and directories used when you boot the system, including:
