I am relatively new to UNIX. From the UNIX machine is there anyway of finding out to what and all other machines is the firewall open.
We usually do telnet <machine_name> <port> to fidn out if the firewall is open. Is there anyway i can get an entire list.
Below is what i did to open the firewall port on
# sudo firewall-cmd --zone=public --add-port=27012/tcp --permanent
Warning: ALREADY_ENABLED: 27012:tcp
success
# sudo firewall-cmd --reload
success
# firewall-cmd --list-all
public
target: default
icmp-block-inversion: no

Alright... this question comes from the fact that I'm trying to setup postfix to relay messages to Office 365 SMTP but its giving me connection refused... I read that if you have doubts if your port is open or not you should telnet to them so thats what I did.

Hi,
So that potential responders will have an idea of what they're dealing with let me say that while I am a UNIX newbie I have been in IT for over 10 years.

fwbuilder(1) Firewall Builder fwbuilder(1)NAME
fwbuilder - Multiplatform firewall configuration tool
SYNOPSIS
/usr/bin/fwbuilder [-ffile.fwb] [-d] [-h] [-ofile] [-Pobject_name] [-r] [-v]
DESCRIPTION
fwbuilder is the Graphic User Interface (GUI) component of Firewall Builder.
Firewall Builder consists of a GUI and set of policy compilers for various firewall platforms. It helps users maintain a database of
objects and allows policy editing using simple drag-and-drop operations. GUI generates firewall description in the form of XML file, which
compilers then interpret and generate platform-specific code. Several algorithms are provided for automated network objects discovery and
bulk import of data. The GUI and policy compilers are completely independent, this provides for a consistent abstract model and the same
GUI for different firewall platforms.
Firewall Builder supports firewalls based on iptables (Linux kernel 2.4.x and 2.6.x, see fwb_ipt(1)), ipfilter (variety of platforms
including *BSD, Solaris and others, see fwb_ipf(1)), pf (OpenBSD and FreeBSD, see fwb_pf(1)), ipfw (FreeBSD and others), Cisco PIX (v6.x
and 7.x) and Cisco IOS extended access lists.
OPTIONS -f FILE
Specify the name of the file to be loaded when program starts.
-r When this command line option is given in combination with -f file, the program automatically opens RCS head revision of the file if
file is in RCS. If file is not in RCS, this option does nothing and the file is opened as usual.
-d Turns on debug mode. Note that in this mode the program generates lots of output on standard error. This is used for debugging.
-h Prints brief help message
-o file
Specify the name of the file for the print output, see option "-P".
-P object_name
Print rules and objects for the firewall object "object_name" and immediately exit. The program does not go into interactive mode.
Print output will be placed in the file specified with "-o" option. If file name is not given with option "-o", print output is
stored in the file "print.pdf" in the current directory.
