[edit] Purpose

This HOWTO is designed for people on Red Hat based systems (Fedora, CentOS, RHEL) who need to edit the Nagios cfg (config) files (commonly found in /etc/nagios) from a Microsoft Windows computer using a Windows-friendly editor, such as Notepad++. This is made possible by mapping a networking drive (z: in our case) to a NetBIOS share we make on the /etc/nagios folder on our Nagios system via Samba.

(This is a very awkward workaround. Ideally such changes would be made via ssh via a text editor such as emac or VI.)

[edit] Samba

[edit] Install

yum install samba samba-client

optional

yum install vim-enhanced

[edit] smb.conf

edit the main Samba config file

vim /etc/samba/smb.conf

# workgroup = NT-Domain-Name or Workgroup-Name
#   workgroup = MYGROUP
   workgroup = NAGIOS
   netbios name = nagios
   security = SHARE
   load printers = No
   default service = global
   path = /etc/nagios/
   available = Yes
   encrypt passwords = yes

[share]
   writeable = yes
   admin users = nagios
   path = /etc/nagios/
   force user = root
   valid users = nagios
   public = yes
   available = yes

# server string is the equivalent of the NT Description field
#   server string = Samba Server
server string = Nagios Server

Allow inbound traffic in smb.conf file.

(Class A requres one octet; class B, two; and class C, three.)

;   hosts allow = 192.168.1. 192.168.2. 127.
   hosts allow = 192.168. 10.

allow Nagios user to also be Samba user

smbpasswd -a nagios
(password)

bounce Samba service and force start upon reboot:

/etc/init.d/smb start
chkconfig --add smb

[edit] iptables (if applicable)

Opening up NetBIOS ports 135 and 137 on IPtables.

vim /etc/sysconfig/iptables

(assuming a fairly default CentOS install)

# Firewall configuration written by system-config-securitylevel
# Manual customization of this file is not recommended.
*filter

:FORWARD ACCEPT [0:0]
:OUTPUT ACCEPT [0:0]

-A RH-Firewall-1-INPUT -j REJECT --reject-with icmp-host-prohibited
COMMIT

bounce IPtables service (to apply changes in iptables script)

/etc/init.d/iptables restart

[edit] Windows Workstation

from start->run->cmd

net use z: \\192.168.1.13\share /user:nagios 

And when you'd like to kill that drive

net use z: /delete

Once you edit these files in Windows, you must restart the Nagios service via ssh (e.g. PuTTY).

/etc/init.d/nagios restart

If that does not work, then try troubleshooting your Nagios cfg file changes

nagios -v /etc/nagios/nagios.cfg

[edit] Notepad++

Open up Notepad++, open up z:, edit your files!
