Bypassing AT&T Fiber/Frontier/AU 802.1X with MikroTik and bridge interfaces

Although I now live primarily in Verizon territory, my family has a second home in Frontier-land at least for a few more months. Frontier in Connecticut inherited AT&T’s 802.1X setup so if you’re not on XGS-PON, you are required to use Frontier’s router, in my case an Arris NVG468MQ. However, if you’re using a MikroTik CCR2004-series router, you can use that connected to the ONT and bridge 802.1X from the Arris. [Read More]

Tech is a cyclical industry: booms and busts are normal

It’s no secret that the tech job market really sucks. Even for me who still has a job, I’m not exactly keen on my department, I have many reservations about my product, I wanted to move on. But even when I tried applying for jobs, why should they hire me instead of someone who’s so desperate they’ll work for less? This just happened to me last week. This made me realize, tech is a cyclical industry. [Read More]

Have an ASN and IPv6 space? Build your own IPv6 tunnel!

For many years, Hurricane Electric was the de-jure IPv6 tunneling platform. If you wanted Netflix, just force Netflix on IPv4. For people without native IPv6, HE.net was truly a godsend. Then HE.net tunnels became more problematic, now we have multiple streaming services and other services blocking HE.net tunnels under the “public proxy” blanket ban. I remember the pre-COVID and the early-COVID era when only Netflix blocked HE.net tunnels when I lacked native IPv6 until summer 2020. [Read More]

Building my own HPE SAS cable from Amazon because HPE won't sell me one

Remember when Reddit /r/sysadmin said HPE support blows? Well it does. I got an open box HPE ProLiant ML110 Gen11 as a NAS. This is my second whereas my first is a compute server. To my surprise, there was no SAS cables in the open box server. When sourcing the official sources, I was in back and forth conversations with HPE and their “part suppliers” to no avail. And no, I did not get the right SAS cable. [Read More]

Running ArchiveTeam Warrior in Podman on Rocky Linux 9

I don’t remember where I heard about ArchiveTeam from, but when I did learn about it I knew I wanted to join in. I have run Tor relays for over a decade now but always wanted to participate in other volunteer-run services as well. I always felt good when my home servers serve more people than just me. I run an I2P node too, but CPU-and-GPU-heavy tasks like Folding@Home are out usually due to excessive power consumption and noise. [Read More]

My High School banned Phones... in 2011!

Today I read that many schools from NYC to LA want to ban smartphones in school. Well, let me tell you that my high school, Somers High School of Somers, NY (an rural-ish but rich NYC exurb) did actually ban phones back in 2011, and when I graduated in 2015 they still did. When it comes to mobile tech, the early-to-mid-2010s were almost like the stone age. Whereas most of my peers had an iPhone on Verizon, my family chose to go with Samsung phones on Sprint.

Taming Noise on HPE ProLiant ML-series Tower Servers

As mentioned earlier, my homelab server is a HPE ProLiant ML110 Gen11 which is a single-socket Intel Sapphire Rapids-based server. One problem with this server is how much noise it generates. I swear, the ML110 Gen10 was much quieter. It’s a big trouble especially since right now I’m “houseless” meaning I’m living with my brother and have my ML110 in a bedroom closet. However, with the default power settings it’s still very noisy especially when running a cluster of Tor relays. [Read More]

Bypassing Frontier Connecticut GPON 802.1X with MikroTik

I’ve made it back eastwards! Yay! While my family looks for NYC hosing, I’m living in Stamford, CT in my brother’s townhouse/condo. The condo has Frontier FiberOptic. But as Connecticut is a former AT&T market, unless you’re on XGS-PON which I’m not, GPON is based off AT&T Fiber with the infamous 802.1X requirement. Initially, I used a Wi-Fi to Ethernet bridge but after having performance issues, I moved the Cat6 drops to near my equipment and “bypassed” the Frontier gateway. [Read More]

Enabling Path MTU Discovery in MikroTik, or why my PPPoE/6rd was slow

For many years, I’ve stuck with OPNsense, first initially since until a couple of years ago I was a die-hard FreeBSD user. But more importantly, by default Linux-based firealls play poorly with CenturyLink’s 6rd. I’ve been wanting to use a MikroTik as my core router instead of OPNsense for many years, but whenever I tried, 6rd browsing was just so slow for some reason. A few days ago, I got myself a MikroTik CCR2004-16G-2S+ and intially went IPv4-only. [Read More]

A MikroTik RouterOS v7 IPv6 BGP Config

As my long-awaited sequel to my MikroTik RouterOS v7 BGP configuration, I will do a RouterOS v7 configuration, but this time with IPv6. The setup will have: R1 with AS1 and R2 with AS2 1::/64 that R1 will advertise 2::/64 that R2 will advertise 3::/64 for the point-to-point link between R1 and R2 3::1 for R1 and 3::2 for R2 The ether1 interface for the R1 and R2 point-to-point links The ether2 interface for the internal, to-be-advertised subnet To setup BGP, first set your IP addresses, on R1: [Read More]
