rcinet(8) System Manager's Manual rcinet(8)
NAME
rcinet - Restarts, starts, or stops Internet network services on the system
SYNOPSIS
/usr/sbin/rcinet option
OPTIONS
You must specify one of the following options with the rcinet command: Restarts the network on the system. Starts the network on the sys-
tem. Stops the network on the system.
You can restrict the restart, start, or stop operation to either IPv4 or IPv6 networks by specifying inet or inet6, respectively, as the
second parameter. By default, the script assumes both IPv4 and IPv6.
DESCRIPTION
The rcinet script allows system administrators to restart, start, or stop the Internet network services on the system while it is running
in multiuser mode by using one of the options.
RESTRICTIONS
Superuser privilege is required.
Warn users that the system is being removed from the network.
File systems that were not mounted using the /etc/fstab file or the automount command must be unmounted with the umount command. You must
remount these file systems using the mount command after the network is started on your system.
ERRORS
The rcinet script prints an error message to stderr if the network is not configured on the system.
FILES
The network shell scripts are located in /sbin/init.d with symbolic links in /sbin/rc0.d and /sbin/rc3.d.
