Copy the Linux hosts file unchanged to Windows as

C:\Windows\system32\drivers\etc\hosts

and add your IP/hostname to the Linux hosts file

@@@.@@@.@@@.@@@ Mathew-PC.localdomain    Mathew-PC

Seems that you can't reach your machine at all.

Does a ping against its IP address work?

ping 192.168.36.1

I'm rather sure that this won't work either, and if so, please examine the network setup of the Windows machine and your network infrastructure (switches/routers, if any).

Is there any way we can edit this file

gedit /etc/samba/smb.conf


# This is the main Samba configuration file. You should read the
# smb.conf(5) manual page in order to understand the options listed
# here. Samba has a huge number of configurable options (perhaps too
# many!) most of which are not shown in this example
#
# For a step to step guide on installing, configuring and using samba,
# read the Samba-HOWTO-Collection. This may be obtained from:
#  http://www.samba.org/samba/docs/Samba-HOWTO-Collection.pdf
#
# Many working examples of smb.conf files can be found in the
# Samba-Guide which is generated daily and can be downloaded from:
#  http://www.samba.org/samba/docs/Samba-Guide.pdf
#
# Any line which starts with a ; (semi-colon) or a # (hash)
# is a comment and is ignored. In this example we will use a #
# for commentry and a ; for parts of the config file that you
# may wish to enable
#
# NOTE: Whenever you modify this file you should run the command "testparm"
# to check that you have not made any basic syntactic errors.
#
#---------------
# SELINUX NOTES:
#
# If you want to use the useradd/groupadd family of binaries please run:
# setsebool -P samba_domain_controller on
#
# If you want to share home directories via samba please run:
# setsebool -P samba_enable_home_dirs on
#
# If you create a new directory you want to share you should mark it as
# "samba-share_t" so that selinux will let you write into it.
# Make sure not to do that on system directories as they may already have
# been marked with othe SELinux labels.
#
# Use ls -ldZ /path to see which context a directory has
#
# Set labels only on directories you created!
# To set a label use the following: chcon -t samba_share_t /path
#
# If you need to share a system created directory you can use one of the
# following (read-only/read-write):
# setsebool -P samba_export_all_ro on
# or
# setsebool -P samba_export_all_rw on
#
# If you want to run scripts (preexec/root prexec/print command/...) please
# put them into the /var/lib/samba/scripts directory so that smbd will be
# allowed to run them.
# Make sure you COPY them and not MOVE them so that the right SELinux context
# is applied, to check all is ok use restorecon -R -v /var/lib/samba/scripts

Add the Windows IP to "hosts allow" .

If "linux" designates another Samba client add this IP to "hosts allow" too.

If "linux" is the Samba server itself add this IP to "interfaces".

There is already "192.168.12.2/24" in interfaces. Is this a typo ("12.2" instead of "2.12")?

You can also omit both directives to allow all local interfaces and all remote hosts.

Samba determines the local interfaces on its own, so there is generally no need for the "interfaces" directive.

Despite the existence of "hosts allow" access still requires suitable user-level passwords,
so use that directive only if there are elevated security requirements.

do you want me to change the whole address

hosts allow = 127. 192.168.12. 192.168.13.

to

hosts allow =192.168.36.1

"127." allows the whole class A range from 127.0.0.1 to 127.255.255.254
"192.168.12." allows the whole class C range from 192.168.12.1 to 192.168.12.254
"192.168.13." allows the whole class C range from 192.168.13.1 to 192.168.13.254
"192.168.36.1" allows just this host.

The "hosts allow" parameter is a comma, space, or tab delimited set of items, so you can specify as many of them as you like.

It's obviously up to you to decide which hosts you're willing to allow access.

What am I supposed to advise here?

Doesn't gedit (or "sudo gedit" if you aren't root) work for you?

gedit /etc/samba/smb.conf

sudo gedit /etc/samba/smb.conf


"vi" is always available, so

vi /etc/samba/smb.conf

sudo vi /etc/samba/smb.conf

http://www.unix-manuals.com/tutorials/vi/vi-in-10-1.html

By the way, is all this still related to your original question about pinging from Windows to Linux?

Samba is a file sharing option and requires an underlying  functional network.
