monitor custom TCP port dalam nagios

Harini ada sorang kawan tanya cam mane nak monitor custom port di nagios. tujuan dia nak monitor custom port sebab ssh port dia dah di "listen" pada port lain ( port 2020). So caranya mudah je.

depend pada cara korang setup nagios, korang kene carik nagis commands.cfg file. mcm aku nyer terletak di /etc/nagis/commands.cfg . ( ade gak orang yg setup di /usr/local/nagios/etc/objects)

gunakan command berikut

vi /etc/commands.cfg

paste seperti di bawah :-

define command{
    command_name check_tcp_2020
    command_line $USER1$/check_tcp -h $HOSTADDRESS$ -p 2020 -4
}

pastu korang kene create service baru untuk host yang nak dimonitor.

vi /etc/nagios/hosts.cfg

kemudian paste bende ni

define host{
    use generic-host ;type generic server kalau linux guna linux-host
    host_name matahari ; nama server kawan aku
    alias server ssh   ; diskripsi server
    address 192,168,1,1 ; server IP
}

pastu paste bawah ni kat services.cfg

define service{
    use generic-service                        
    host_name matahari                          
    service_description 'check ssh port2020/tcp' 
    check_command check_tcp_2020                
}

Verify config betul ke idak

# nagios3 -v /etc/nagios3/nagios.cfg

mcm kawan aku dia kene guna cmd ni

# /usr/local/nagios/bin/nagios -v /usr/local/nagios/etc/nagios.cfg

pastu korang akan dapat cam ni

Kalau semua nya ok, boleh la restart nagios.

# /etc/init.d/nagios restart

settle.

cool website

hari ni selesai sudah mengsetup netbook rufleen :D . terjumpa website menarik http://ninite.com/
secara am, website ni membolehkan kebanyakkan software yang diperlukan selepas kita selesai "clean install". menariknya kita tidak perlu download program2 tersebut secara individu. melalui website ini, segalanya boleh di download sekali gus. memang best :D

Null Route

In computer networking, a null route (blackhole route) is a network route (routing table entry) that goes nowhere. Matching packets are dropped (ignored) rather than forwarded, acting as a kind of very limited firewall. The act of using null routes is often called blackhole filtering. The rest of this article deals with null routing in the Internet Protocol (IP).

Null routes are typically configured with a special route flag, but can also be implemented by forwarding packets to an illegal IP address such as 0.0.0.0, or the loopback address.

Null routing has an advantage over classical firewalls since it is available on every potential network router (including all modern operating systems), and adds virtually no performance impact. Due to the nature of high-bandwidth routers, null routing can often sustain higher throughput than conventional firewalls. For this reason, null routes are often used on high-performance core routers to mitigate large-scale denial-of-service attacks before the packets reach a bottleneck, thus avoiding collateral damage from DDoS attacks — although the target of the attack will be inaccessible to anyone. Blackhole filtering can also be abused by malicious attackers on compromised routers to filter out traffic destined to a certain address.

However, routing typically only works on the Internet Protocol layer and is very limited in packet classification. It is bound to be stateless due to the nature of IP routers. Typically, classification is limited to the destination IP address prefix, source IP address and incoming network interface.

Nullrouting with iproute2 on Linux:

$ ip route add blackhole 192.168.32.128/32[1]

Nullrouting with 'route' on Solaris and BSD:

$ route add -host 10.10.0.1 127.0.0.1 -blackhole
$ route add -net 10.10.64.0/18 127.0.0.1 -blackhole


Routing to the Null0 interface on Cisco IOS:

ip route 192.168.0.0 255.255.0.0 Null0[2]

Windows XP/Vista does not support reject or blackhole arguments via route, thus an unused IP address (e.g. 192.168.32.254) must be used as the target gateway:

route -p ADD 192.168.32.128 MASK 255.255.255.255 192.168.32.254
