you already can install icinga2 via FreeBSD ports. the configuration will be done per cli only until now but it works very well

it's nearly the same to configure a satellite or a agent node. personally i don't need the satellite feature on my OPNsense. i am fine with the basic agent functionality

if you want to create a satellite you have to define a new satellite zone.

1. put your choosen zone name in constants.conf

Code: [Select]

...
const ZoneName = "<MY-SATELLITE-ZONE>"
...

2. zones.conf didn't need any changes

Code: [Select]

/*
 * Generated by Icinga 2 node setup commands
 * on 2017-11-17 18:56:55 +0100
 */

object Endpoint "<MASTER-FQDN>" {
        host = "<MASTER-IP>"
        port = "5665"
}

object Zone "master" {
        endpoints = [ "<MASTER-FQDN>" ]
}

object Zone "global-templates" {
        global = true
}

object Endpoint NodeName {
}

object Zone ZoneName {
        endpoints = [ NodeName ]
        parent = "master"
}

on your master you have to define the agent node as endpoint object in your choosen satellite zone. there you have to store the config in /etc/icinga2/zones.d/<MY-SATELLITE-ZONE>/endpoints.conf

Code: [Select]

object Endpoint "<AGENT-NODE-FQDN>" {
    host = "<AGENT-NODE-IP>"
    log_duration = 0s
}

object Zone "<AGENT-NODE-FQDN>" {
    parent = "<MY-SATELLITE-ZONE>"
    endpoints = [ "<AGENT-NODE-FQDN>" ]
}

if the key exchange for the encrypted connection was successfully the master will sync the satellite specific configuration to the satellite node. you can check the receipt of objects under /var/lib/icinga2/api/zones/*.


3. disable the include of local config objects in icinga2.conf to avoid the deployment of double objects

Code: [Select]

...
#include_recursive "conf.d"
...

sorry, i've forgot to mention the need of the package called monitoring-plugins (net-mgmt/monitoring-plugins). it contains all of the common check plugins for local and remote checks.

all right. here is a example config for a agent node scenario:

const PluginDir = "/usr/lib/nagios/plugins"

const ManubulonPluginDir = "/usr/lib/nagios/plugins"

const PluginContribDir = "/usr/lib/nagios/plugins"

/* Our local instance name. By default this is the server's hostname as returned by `hostname --fqdn`.

as mentioned above the port is called net-mgmt/icinga2. withit you can setup a icinga2 master instance (server), a satellite instance or basically an agent node. the agent node is useful to run local checks, for example checking the hardware-environment, special squid checks, local filesystem checks etc.

what did you exactly mean with config? do you need a example icinga2 config or a kind of config to build the package? excuse me this question, i'm not really familar with building a package from source.

i would also like to see a icinga2 package. unfortunately i had no luck to compile the source code myself

Mit dem heutigen Update ist die Funktion nun enthalten Backups in der eigenen Nextcloud abzulegen. Was für ein Kennwort wird denn für die Verschlüsselung der Konfigurationsdatei benutzt?

Danke für Deine Hilfe pingus

Ich bin Deinen Anweisungen gefolgt und konnte zuerst den HAProxy Dienst nicht starten. Der Fehler hierbei war, das ich bei der Frontend Listen Address das "*:443" zu wörtlich genommen habe. Hier muss scheinbar neben dem Port eine vollständige Adresse eingetragen werden. Ich habe nun "127.0.0.1:443" eingetragen und per NAT-Regel 443/TCP auf den lokalen Port 443, auf dem der HAProxy lauscht (siehe sockstat-Ausgabe), umgeleitet.

NAT-Regel

Code: [Select]

WAN TCP * * WAN address 443 (HTTPS) 127.0.0.1 443 (HTTPS)   

FW-Regel

Code: [Select]

IPv4 TCP * * 127.0.0.1 443 (HTTPS) * NAT   

Code: [Select]

sockstat | grep haproxy
www      haproxy    17125 4  dgram  -> /var/run/log
www      haproxy    17125 5  stream /var/run/configd.socket
www      haproxy    17125 6  stream /var/run/configd.socket
www      haproxy    17125 9  stream /var/run/haproxy.socket.16847.tmp
www      haproxy    17125 10 tcp4   127.0.0.1:80          *:*
www      haproxy    17125 11 dgram  (not connected)
www      haproxy    17125 12 tcp4   127.0.0.1:443         *:*
root     syslogd    22806 6  dgram  /var/haproxy/var/run/log

Der HAProxy läuft nun aber meine Seite (Nextcloud-Installation) ist von außen nicht erreichbar. Nach ca. 30 Sekunden gibt es einen Timeout/Reject. Im Firewall Log tauchen keine Meldungen auf, im HAProxy Log hingegen schon. Dort sehe ich mehrmals die Zeile:

Code: [Select]

German - Deutsch / Reverse Proxy mit HAProxy-Plugin

« on: April 29, 2017, 02:46:47 pm »

Hallo Forum,

ich versuche mich gerade daran OPNsense für mein privates Netzwerk einzurichten und komme auch ziemlich gut voran. Interfaces, VLANs, DNS, DHCP, OpenVPN, Squid und das LetsEncrypt-Plugin konnte ich konfigurieren - das funktioniert soweit

Was mir aktuell noch fehlt ist ein Reverse Proxy. Laut den Hinweisen/Empfehlungen hier im Forum soll man hierfür das HAProxy-Plugin verwenden. Leider scheitere ich aufgrund der umfangreichen Konfigurationsmöglichkeiten daran das Plugin für mich richtig einzustellen.

Kann mir bitte jemand unter die Arme greifen und grob die Schritte nennen die auszuführen sind um folgende Anforderung umzusetzen?

Ich möchte das alle eingehenden WAN-Anfragen betreffend HTTP/HTTPS an den Reverse Proxy umgeleitet werden. Der Proxy soll dann, wie bei den Squid Peer Mappings, anhand der aufgerufenen URL die Anfragen an einen bestimmten Webserver im LAN weiterleiten.

Danke & Gruß,
vita
