APIBAN now supports Cisco and Juniper formats

We recently made some dramatic enhancements to the APIBAN infrastructure. As I joked on Mastodon, I must be getting older as these improvements were made well before an emergency. If you’re not familiar, APIBAN helps prevent unwanted SIP traffic by identifying addresses of known bad actors before they attack your system. Bad actors are collected through globally deployed honeypots and curated by LOD. You can access this data via API or automatically block the traffic with our open source client....

Sangoma Still Doesnt Get Open Source

Disclaimer: The views expressed in this post are solely my personal views and opinions. These do not necessarily represent the views and opinions of any company or project that I am (or have been) associated with. Back in 2019 (around 3.5 years from this post), I blogged that Sangoma Doesn’t Get Open Source. The post generated a decent amount of discussion and later that year, Dan Jenkins and I sat with Bill Wignall and made commitments about future conferences, handling “open source,” and stopping FUD....

Thanksgiving Message 2022

Another year, another quiet Thanksgiving in Gainesville. Later on this week, we’ll be celebrating my daughter’s 4th birthday. Still coming to terms with how quickly the time passes. Choosing to stay local and not visit family is a choice made for one reason: my daughter loves birthday celebrations at her home. She’s been planning what she wants for months now. When it comes down to it, choosing to make her birthday special is an easy choice....

I Have Left Twitter

I’ve learned a few things from Michael White throughout the time we’ve been friends. The most important being to make a mantra of Happy Wife. Happy Life. When I first joined twitter in 2008, it was a fun way to socialize with people from all over the globe. Twitter was gaining popularity within the open source telecom world and many of us would share posts, opinions, photos, whatever. The length of the tweet was perfect for sharing short thoughts and back then, there weren’t a ton of people on the platform....

Git Repo with Custom SSH Key

I love git. Love it. I’ll save my love for Gitea for another day (TL;DR: Gitea is awesome). Anyway, a lot of git repositories allow you to use ssh keys as authentication. This is a great thing, but of course, sometimes can be difficult to manage if lets say one repo for work uses one key and one that you use for a side project uses a different ssh key....

Opening Compressed PCAPs with SNGREP

The wonders of troubleshooting SIP never cease. Ever try to open a pcap with sngrep only to get the following error? Couldn't open pcap file XYZ.pcap: unknown file format And then, even though you hate looking at SIP on wireshark, you are left wondering… Why does this file open in Wireshark, but not in sngrep? Well, most of the time, this is because the pcap file is actually compressed. Easy fix....

ITEXPO 2022

Well, ITEXPO 2022 has come and gone. I think there were perhaps 2-3 other people at the conference who wore a mask. This said, I did return home without covid… The presentation was interrupted by a fire alarm. Apparently some idiot decided it would be fun to smoke in the bathroom. Wasn’t cool in the 80s, still isn’t cool today. Anyway… Unfortunately, coordination was very lacking at the event and no information regarding extending time made it to any of the presenters/attendees in our room....

For My Security

When the bakery closed during Covid, one reason was Bank of America’s delays in handling of our emergency loan (PPP) request. That’s a different story for another time, but the bottom line is that I moved from Bank of America to a credit union (for both business and personal banking). Recently, the credit union attempted to update their online banking. It’s a disaster and customers have been without access to transfers, bill pay, balances, etc for over 2 weeks....
