Typically, the authentication protocol is set by the monitored device. For SNMPv3, you can test the device's SNMP response with something like this: snmpbulkwalk -v 3 -u [USER] -l authPriv -n [CONTEXT_IF_USED] -a [AUTH_PROTO] -A [AUTH_PASS] -x [CRIPT_PROTO] -X [CRIPT_PASS] -On [MONITORED_HOST]...

The error indicates that the application is already installed. Sorry, I forgot to mention that you should remove the Zabbix Agent in addition to the configuration files. Then try again.

Hi @bigAboo When you list the active parameters from the agent's configuration file, we see that the Include parameter is active and points to the /etc/zabbix_agentd.conf.d directory. However, the error message indicates that it does not exist. The Include parameter allows you to add additional...

Indeed, it may not be the best user script to add a cron task. I think I got it from this Merlin's wiki. init-start works for me, but you could probably use something else like services-start, nat-start or ddns-start.

After failing to create a custom Inadyn DDNS configuration for deSEC.io that would update both IPv4 and IPv6, I've created a script that updates my deSEC domain IP. It is a simple yet effective script that updates a deSEC.io domain name with the latest WAN IPv4 and IPv6 addresses. It uses...

I see. Thanks for the tip. Indeed, DNS Director is the one to blame. When I switch to global "no redirection", the rule is unset and all requests to port 853 work properly. However, when global redirection is enabled, packets for port 853 from different hosts are rejected instead of...

While testing out an AdGuard Home instance on a Docker container, it failed to reach upstream TLS servers. Upon closer inspection, I traced the packets back to the AX86U router IPTables. There is a chain called "DNSFILTER_DOT" that is blocking any packet on port 853 that is not destined for...

I guess so. I think that, for any surge to reach the WAN port, it would have to go through the UPS, which should have protections, the modem, and finally the router. I find this odd because the WAN port is connected to the modem and it did not suffer any loss. I'll check that with the owner...

Recently my RT-AX86U router failed to connect to the Internet. My setup has an ISP cable modem connected in bridge mode to the Asus router. After some possible lightning in the area, it seems that the WAN and 2.5G ports have completely stopped working. The device boots up and I'm able to connect...

Zabbix template for AdGuard Home If you're using Zabbix to monitor your network and want to collect statistics from your AdGuard Home instance, I've created a Zabbix template that provides some useful monitoring items. The monitoring is agentless via a "REST-ish" API, since AdGuard Home offers...

So, buildno= current version (is this equal to productid?) webs_state_info= new version webs_state_flag= after check, indicates there is a new version Is that correct?

I see. Nevertheless, when a check is performed does it store the new value in the NVRAM? Do these NVRAM parameters actually store the current and new versions?

I'm using a RT-AX86U and it has a "Scheduled check for new firmware availability" feature. I see that whenever a new update is available, a flashing bell appears at the top of the webpage. Regarding this schedule, how often does it run? Is the schedule configurable? I see that there are a...

Great guys. It's getting even better. Dig was so much cleaner... I vote to add it to the base firmware. 🖐️ But you're right. Next time I reset the router, I may forget to install it. I could try something like this with Nslookup: NEWIP=$(nslookup $DDNSNAME 127.0.0.1 | awk 'NR==5 { print $3 }) I...

I think the IPTables Replace command should suffice. # Set up the domain, ip and port DDNSNAME=$1 EXTPORT=$2 NEWIP=$(dig +short @127.0.0.1 $DDNSNAME) # Considering the chain rule number is unknown, I need to filter it LINENUM=$(iptables --line-numbers -n -t nat -L VSERVER | grep...
