In this guide I just install configure SNMP daemon on Proxmox. SNMP is used to read out the state of the machine, this includes CPU, network (-traffic, -settings,…), memory, … I can suggest LibreNMS, for the monitor. Back to setting SNMP daemon up !
Install the service
apt-get install snmpd
Config the service
I like to backup the original configuration (for documentation) :
mv /etc/snmp/snmpd.conf /etc/snmp/snmpd.conf.ori
Then I create the config file : /etc/snmp/snmpd.conf
# this create a SNMPv1/SNMPv2c community named “my_servers”
# and restricts access to LAN adresses 192.168.0.0/16 (last two 0’s are ranges)
DNS-Over-HTTPS is a protocol for performing DNS lookups via the same protocol you use to browse the web securely: HTTPS.
With standard DNS, requests are sent in plain-text, with no method to detect tampering or misbehaviour. This means that not only can a malicous actor look at all the DNS requests you are making (and therefore what websites you are visiting), they can also tamper with the response and redirect your device to resources in their control (such as a fake login page for internet banking).
DNS-Over-HTTPS prevents this by using standard HTTPS requests to retrieve DNS information. This means that the connection from the device to the DNS server is secure and can not easily be snooped, monitored, tampered with or blocked. It is worth noting however, that the upstream DNS-Over-HTTPS provider will still have this ability.
Here we are downloading the precompiled binary and copying it to the /usr/local/bin/ directory to allow execution by the cloudflared user. Proceed to run the binary with the -v flag to check it is all working.
Proceed to create a configuration file for cloudflared by copying the following in to /etc/default/cloudflared. This file contains the command-line options that get passed to cloudflared on startup.Copied to clipboard
