ports and services
hello all,
in order for me to close ports and remove services that could be a danger to my system i have edited the /etc/initd.conf file, /etc/system file, and renamed some of the r commands. However i wanted to know if anyone knows how to turn off all services and close ALL known ports, so i can open them as i go forward with my installation of new apps etc, etc.
This is Solaris 8 system on a sparc machine
Thanks for your time in advance

Hi Team,
I am using RHEL 7.3.
I had added few port numbers in
/proc/sys/net/ipv4/ip_local_reserved_ports.
Now how do I verify that kernel does not allow to a service which requests random ports for its services.

services
services(4) File Formats services(4)
NAME
services - Internet services and aliases
SYNOPSIS
/etc/inet/services
/etc/services
DESCRIPTION
The services file is a local source of information regarding each service available through the Internet. The services file can be used in
conjunction with or instead of other services sources, including the NIS maps "services.byname" and the NIS+ table "services." Programs
use the getservbyname(3SOCKET) routines to access this information.
The services file contains an entry for each service. Each entry has the form:
service-name port/protocol aliases
service-name This is the official Internet service name.
port/protocol This field is composed of the port number and protocol through which the service is provided, for instance,
512/tcp.
aliases This is a list of alternate names by which the service might be requested.
Fields can be separated by any number of SPACE and/or TAB characters. A number sign (#) indicates the beginning of a comment; any charac-
ters that follow the comment character up to the end of the line are not interpreted by routines which search the file.
Service names may contain any printable character other than a field delimiter, a NEWLINE, or a comment character.
Any changes to a port assignment do not affect the actual port registration of the service.
FILES
/etc/nsswitch.conf configuration file for name-service switch
SEE ALSO
getservbyname(3SOCKET), inetd.conf(4), nsswitch.conf(4)
NOTES
/etc/inet/services is the official SVR4 name of the services file. The symbolic link /etc/services exists for BSD compatibility.
