Fonera – Client Mode config as backup WAN

25 December 2020 by Ing. Lele

Start from factory default: Admin > Factory Defaults > Yes > Save

Note: if La Fonera lose connectivity or IP, connect via 169.254.255.1

Main changes to perform:

Setup > Basic Settings

Internet Connection Type: Automatic Configuration – DHCP.
Local IP: 192.168.Z.Y, where Z is any number between 1 and 255 that IS NOT the same as X in the host router settings. I used 192.168.3.1 for my tests.
Subnet: 255.255.255.0, or whatever is identical to the same setting in the host router.
Gateway & Local DNS: Leave these blank or the same as your host router’s Local IP.

Wireless > Basic Settings

Before altering the following, change Wireless Channel to an identical setting to the host router’s Wireless Channel. In my tests I used 11 (2.426 GHz). Hit save settings and continue with the guide. This setting will be unavailable after changing to Client mode.

Wireless Mode: Client.
Wireless Network Mode: Mixed. A setting identical to the host router is all that has been tested. Either using mixed on the La Fonera, or a separate setting that is identical to the same Wireless Network Mode used on the host router, will probably work.
“G-Only” on host OR both host & fon will not work – freonchill
Wireless Network Name (SSID): Identical to the same SSID in the host router.

Wireless > Wireless Security

Change the Security Mode for the Physical Interface to the same settings used on the host router.

At this point, if all settings are correct and the Fonera has connected as a client to the host router, the Fonera should now have gained an IP address from the host router.

Main guide is at DD-WRT forum: LaFonera Software Client-Mode

UniFi USG + Switch + AP – How to configure WAN Failover

25 December 2020 by Ing. Lele

UniFi Secirty Gateway (USG) WAN failover capability is not working using configuration UI. Here is step by step on how to have it working correctly.

Below you can find content of config.gateway.json to upload via WinSCP.

If you don’t have CloudKey, the correct path inside PC is “C:\Users\<username>\Ubiquiti UniFi\data\sites\default“

{
     "load-balance": {
         "group": {
             "wan_failover": {
                 "flush-on-active": "enable"
             }
         }
     }
 }

Milestone XProtect Mobile Server – SSL Certificate configuration

18 December 2019 by Ing. Lele

Install XProtect PowerShell module to manage Mobile Server as reported in the video above:

Install-Module Posh-XProtectMobile

Follow this article: MileStone XProtect 2019 R2 – How to generated trusted certificate on how to get certificate via MyCertWeb and free top level domain from http://My.dot.tk

Once installed in the system, Powershell will help to configure the certificate automatically:

Get-Help Set-MobileServerCertificate -examples

Sets the sslcert binding for Milestone XProtect Mobile Server when provided with a certificate, an object with a Thumbprint property, or when the -Thumbprint parameter is explicitly provided.

The Thumbprint must represent a publicly signed and trusted certificate located in Cert:\LocalMachine\My where the private key is present.

Set-MobileServerCertificate [-X509Certificate ] [[-Thumbprint] ]

You can get X509 certificate object using this command:

PS C:\WINDOWS\system32> $MyCert = gci Cert:\LocalMachine\My | ? Subject -eq 'CN=my.domain.tk'
PS C:\WINDOWS\system32> $MyCert

 Thumbprint Subject
---------- -------
<GUID> CN=my.domain.tk

Once you have verified the certificate is correct, you can push configuration to Mobile Server with this:

Set-MobileServerCertificate -X509Certificate $MyCert

Set-MobileServerCertificate -Thumbprint <GUID>

To remove certificate at IIS level and check IIS configuration, use these:

netsh http delete sslcert ipport=0.0.0.0:8082

netsh http show sslcert ipport=0.0.0.0:8082

XMR on Azure – RandomX fork

10 December 2019 by Ing. Lele

https://cryptomining-blog.com/wp-content/uploads/2019/09/monero-xmr-randomx-fork.jpg

Monero network upgrade to new RandomX fork was scheduled on 11/30 and new xmr-stak version dropped support for Monero, so new steps to setup xmrig v5.1.0.

All Azure batch configuration remain the same as reported in original article and uses startup script save in Azure Storage Account

Configuration wizard allows to generate config.json file needed:

{
    "autosave": true,
    "donate-level": 5,
	"randomx": {
        "init": -1,
        "mode": "auto",
        "1gb-pages": true,
        "wrmsr": 6,
        "numa": true
    },
    "cpu": {
	    "enabled": true,
        "huge-pages": true,
        "hw-aes": null,
        "priority": null,
        "memory-pool": false,
        "yield": true,
        "max-threads-hint": 100,
        "asm": true,
        "argon2-impl": null,
        "cn/0": false,
        "cn-lite/0": false
    },
    "opencl": false,
    "cuda": false,
	"log-file": "xmrig.log",
    "pools": [
        {
            "url": "ca.minexmr.com:443",
            "user": "your_wallet_here",
            "keepalive": true,
            "tls": true
        }
    ],
    "print-time": 60,
    "health-print-time": 60,
	"retries": 5,
    "retry-pause": 5
}

Upload config.json to your Azure Storage Account as it will be used inside VM. You can create a custom CPU configuration and optimize for RandomX

Ubuntu build, Huge Page optimization and command line to start miner is:

sudo ./xmrig -c=config.json

The new setup_xmr_f16_v6.sh file used as startup script in Azure Batch is like this:

sudo apt-get --assume-yes update
sudo apt-get --assume-yes install git build-essential cmake libuv1-dev libssl-dev libhwloc-dev
git clone https://github.com/xmrig/xmrig.git
mkdir xmrig/build
cd xmrig/build
cmake ..
make -j$(nproc)
wget https://your_storage_account.blob.core.windows.net/miner/f16/config.json
sudo sysctl -w vm.nr_hugepages=1280
sudo bash -c "echo 3 > /sys/devices/system/node/node0/hugepages/hugepages-1048576kB/nr_hugepages"
screen -dmS monero sudo ./xmrig -c=config.json

To monitor xmrig miner =

tail -s 5 -n 100 -f /mnt/batch/tasks/startup/wd/xmrig/build/xmrig.log
sudo hscreen -r -S monero

For troubleshooting, review these folders:

# Azure Batch startup script location
cd /mnt/batch/tasks/startup/wd/

# xmrig build folder
cd /mnt/batch/tasks/startup/wd/xmrig/build/

MileStone XProtect 2019 R2 – How to generated trusted certificate

7 July 2019 by Ing. Lele

MileStone Essential+ is great video surveillance software which support 8 cams for free and it’s design to expand to more with paid versions.

I use it at home with 4 cameras and new version 2019 R2 enforce a new level of security to use trusted certificates and deprecate old self-signed certificate which most mobile OSes refuse to verify.

Easiest way to generate it is via CertifyTheWeb which will generate a free SSL certificate for 3 months and you can renew it for free.

I used Azure DNS validation to confirm I own the website and publish it automatically on my local ISS website.

To get a public website, you can use my.dot.tk

PNB – Themes & Variations

30 May 2019 by Ing. Lele

The season’s final mixed bill promises intriguing variety. Balanchine’s resplendent Theme and Variations represents the height of classical purity and elegance, while his zesty Tarantella pas de deux dazzles with virtuoso fun. In Jose Limon’s masterpiece, The Moor’s Pavane—a reduction of Shakespeare’s Othello—riveting characterizations cast a powerful spell. The line-up is joined by the return of our own Price Suddarth’s electric Signature.
