    An Arris modem replaced the Xfinity modem. The Mac on the Wifi returns web pages (i.e. internet is working). The Mac is also able to ping the Honeywell thermostat: ping -c 3 192.168.8.121 I noticed two services that seem to fail: * Thermostat display normally reports outside temperature...

    Immediately forcing DDNS update

    DDNS indicates "Unable to connect to the Internet": leaving me to wonder why? @ColinTaylor: Thank you for the reply. Router replies "Done." to Terminal command. ISSUE: nslookup does not return the WAN IP in the photo. I suspect this is because of the "Unable to connect to the internet"...

    DDNS: WAN IP

    A customer has asked to create a sub LAN with an Asus Merlin router. The DSL modem assigned the 192.168.1.84 to the Merline router: The goal is to have the DSL modem forward inbound SSH to XYZ.asuscomm.com to the Asus router. The DSL modem has been configured to do this, however...

    DNS Troubleshooting

    All wifi devices were working prior to resetting the router's NVRAM. After the reset, Wifi service was restored and the OSX / IOS wifi devices are running well. DNS-based Filtering (Quad9 Global Filter Mode) was turned on and seems to cause a problem DNS resolution problem on in the Ubuntu...

    DHCP Clients are not returned

    I maintain several routers and should keep a log for each one. That said, this router was upgraded from an older Merlin version, that was working perfectly (this is where the log would be handy). I have tried rebuilding the NVRAM with the procedure: ** Power off the router ** Hold the...

    DHCP Clients are not returned

    An RT-AC68U is outfitted with 384.13 performs as expected, except DHCP clients do not populate the client list: What diagnostics steps can be taken to determine root-cause and corrective action?

    The goal is to enable Firefox (on Ubuntu 16.04) to remotely ssh-tunnel and administer the Merline home router. The command: ssh -D localhost:3000 user@myfqdn.asuscomm.com connects a BASH terminal to the SSH server (on the router). Firefox network settings was configured per...

    configuring optware services to start at boot

    Optware is installed on an Asus RT-N16 Firmware:374.43_2-39L3j9527 I understand that Optware is now superseded by Entware, but have my reasons for not migrating (yet). Goal: configure openssh-sftp-server to start at boot. What are the steps? Ideally these steps would be extensible to other...

    Mounting USB drive

    An attempt to standup an RT-N16 on K3.X DD-WRT was abandoned in favor of John's Merlin-fork. Firmware:374.43_2-39L3j9527 The flash drive was accessible from DD-WRT and was reformatted to EXT4. The screenshot show that the router recognizes the Sandisk USB drive, but it is umounted. What...

    Add DHCP static leases from CLI

    It is convenient to be able to add a list DHCP reservations from the CLI (Telnet / SSH). The NVRAM variable: dhcp_staticlist stores dhcp static leases: <MAC_Addresses> LAN_IPs>hostnames< for example: <B8:27:EB:F6:55:55>192.168.8.6>rapsberrypi< nvram show dhcp_staticlist An example for...

    Firmware Model Validation

    "Asus is now enforcing stricter model validation on the RT-AC68U series at flash time." From: https://www.snbforums.com/threads/the-tm-ac1900-is-not-supported.48056/ I am trying to understand in the quote: is 'Asus' referring to the CFE firmware or is there some other force performing a...

    Uploading IOT data via scripts

    A thermostat device returns JSON like data from the command line: curl -s http://192.168.X.Y/tstat/humidity {"humidity":51.00} A cron job wass configured to execute a .sh UNIX script to save data to a USB memory stick. The next step in the pedagogical exercise is to upload data to a...

    VPNFilter Malware

    I think we are in agreement here. Vaccines \ antibiotics address a limited spectrum (scope) of pathogen-variants, which regularly mutate to seemingly counter vaccines in a 'cat and mouse' game (Influenza comes to mind). I think that VPNFilter is a specific pathogen strain (maybe this is not...

    Asus RT-AC66U DNS hacking

    Is it possible to replace the suspect router with a new device? It would be interesting to see if you experience the same symptoms. I would expect that there will be a VPNFilter - router test in the future, which could be applied to the suspect device.

    VPNFilter Malware

    The operating mechanisms of the malware are known: is it not possible to build new firmware and configure user & network settings that will defend against the attack? If not, why?
