Cisco Router config: ip wccp web-cache ! interface Loopback0 ip address 30.0.0.1 255.255.255.0 ip ospf 1 area 0 ! interface FastEthernet1/0 description ++ TO WEBCACHE ++ ip address 10.111.1.1 255.255.255.252 duplex auto speed auto ! interface FastEthernet1/1 description ++ TO INTERNAL […]
I’m currently preparing to move from an old Nagiosto a new Icinga installation and therefore I wrote another check script. There’s already a plugin available with lots of checks but it fails to monitor devices where HSRP load balancing is enabled so I decided to write my own script. Here’s my sourcecode, you can copy […]
