Make sure your current TTL isn't 24hrs at least 24hrs ahead of time... I've seen so many disorganized migrations have to get delayed due to the lack of forethought.

Nice job, all! We have over 1,000 subscribers. Remember, this is a community, so the more submissions/posts, the more content!
As the CentOS Stream community grows and the enterprise software world tackles new dynamics, we want to sharpen our focus on CentOS Stream as the backbone of enterprise Linux innovation. We are continuing our investment in and increasing our commitment to CentOS Stream. CentOS Stream will now be the...
In a 2018 lawsuit, an ex-employee said he warned OceanGate about a lack of testing and was fired for raising concerns, claiming paying customers were left in the dark.
Oooof. Experimental, unregulated, unclassified vessel to take me to the Titanic? Sign me up!
If I had a niche in networking that I specialize in, it would be 'border security.' It makes me laugh that everyone in security markets zero trust and CASB and says networks are 'borderless' - it's just not true. I am constantly dealing with borders between 'fabrics' and locations. Maybe I'm just a dullard, but I see the niche I am working in only become more important as we move to the cloud and distributed networking and security paradigms.
I've been watching For All Mankind and it got me thinking about networking in space... TTLs, 64k packets, transmission mediums, etc. As a 'network generalist,' I find more and more niches to deep dive into... If you specialize in a certain networking niche, what is it? Would you consider networking in space?

KillNet, Anonymous Sudan, and Pinchy Spider (a.k.a. REvil) reportedly announced a large-scale attack aimed against European and US financial institutions due to be launched on 16 June 2023. The announcement was made in a video distributed through the official Telegram channel of Anonymous Sudan.
The first target will allegedly be the SWIFT payment system with the intention to “paralyze it.” This campaign appears to be a collaboration between the three known threat groups. While Killnet actors are known for their DDoS attacks, Killmilk, the group’s leader, stated this will not be a DDoS attack. Anonymous Sudan is not known for advanced attacks of this magnitude; however, Pinchy Spider, the group behind REvil ransomware, is a quite advanced actor.
Killnet stated “Nothing will save you, and this is not a warning – I’m just informing you. You have not encountered such problems yet.” and “This is not a DDoS attack, games are over. “No money – no weapons – no Kyiv regime” – this formula will work.” An Anonymous Sudan spokesperson added “Many European banks will be targeted and we will hit without mercy.”
These attacks appear to be in protest of the West’s financial and military support to Ukraine.
Depends on use case. 10Gbps between switches (core, distribution, and access) is fairly commonplace and cheap. Per access to the host... only new access switches have multi-Gig ports (1,2.5,5,10Gbps). Those are expensive and are reserved for wireless APs, IME, as they service more than just a host.
Before the APIs are shut down, if you want to wipe your reddit account, I found JavaScript-based account wiper to work quite well and is aligned with security best practices called 'PowerDelete Suite.'
Once logged into your reddit account, drag the red button to your bookmark bar and click it. That initiates the script that will work on your reddit account.
You have options to overwrite your comments before deleting them, just deleting them, downloading your data, etc. Very thorough.
Boot Script Code
javascript:
(
function()
{
window.bookmarkver = '1.4';
var isReddit = document.location.hostname.split('.').slice(-2).join('.') === 'reddit.com';
var isOverview = !! document.location.href.match(/\/overview\b/i);
if (isReddit && isOverview)
{
var cachBustUrl = 'https://raw.githubusercontent.com/j0be/PowerDeleteSuite/master/powerdeletesuite.js?' + (new Date().getDate());
fetch(cachBustUrl).then
(
function(response)
{
return response.text();
}
).then
(
function(data)
{
var script = document.createElement('script');
script.id = 'pd-script'; script.innerHTML = data;
document.getElementsByTagName('head')[0].appendChild(script);
}
).catch
(
function(){alert('Error retreiving PowerDeleteSuite from github');}
);
}
else if (confirm('This script can only be run from your own user profile on reddit. Would you like to go there now?'))
{
document.location = 'https://old.reddit.com/u/me/overview';
}
else
{
alert('Please go to your reddit profile before running this script');
}
}
)
();

Ya know, it's sorta funny that this kind of connectivity is what started 'workgroup' networks... ThickNet, ThinNet, etc. Ring topology is a good idea until you mix people and their computers in!
Funneling the herd into the slaughterhouse.
Ha! At home I run a Ubiquiti stack with my lab hung off it (switches, ASA, FortiGate).
I read 'The Iliad,' 'The Oddysey,' and 'Beowulf' when I was in high school. Followed by parts of 'Inferno' and 'Cantebury Tales.' In college when studying Japanese, I read 'The Tale of Genji.'
The long form of 'sagas,' whether in poetic or prose form, pull me in. What are some long-form myths and tales you enjoy?
What's the 'freakiest' event or situation you've experienced in production?
Looked down at my ThinkPad dock to plug in a USB device and saw a 10 next to it. USB.org has specs on a 10Gbps serial bus.
Time to trash the network. I'm getting a 10Gbps 24-port USB hub. :D
Conceptualizing time and the spiritual realm has always been made easier for me with visuals. 'The Evolutionary Tree of Religion (Faith, Myths, & Mysticism) v2' by Simon E. Davies is probably my favorite way to explore how humans perceive the supernatural.
Do you have a preferred vendor for your network gear?
I'll go first:
- Firewalls: Fortinet, ASA, Palo Alto
- Route/Switch: Cisco, HPE/Aruba
- Wireless: Aruba, Cisco, Meraki
- Auth: NPS, ISE, ClearPass
- Monitoring: SolarWinds, Auvik, PRTG
- Automation: Ansible
- SDWAN: PA Prisma SDWAN, Fortinet, Velocloud
Enterprise network and security is where I spend most of my time and thought there may be others out there who want to commiserate with me.
