feld··on A Call to Arms: Supporting Matrix
well, end to end crypto for one
feld··on Exercise as a Preventive or Disease-Modifying Treatment for Dementia Brain Aging
Except the increased risk of heart attack and the damage to kidneys and bowels...
feld··on FreeBSD deprecates all r-cmds (rcp, rlogin, etc.)
Netflix gives back major fixes and performance improvements to the community because maintaining their own fork of the OS permanently is a nightmare.
feld··on Tesla Model 3 Hits Production
My friend put 100,000 miles on his Tesla in a year and was never stranded. He drove 30,000 miles on a known faulty motor.

It's not more unreliable than an ICE vehicle. It's significantly more simple in design and for repair. These claims are FUD.

feld··on Explain like I’m 5: Kerberos (2013)
FreeBSD, OpenSSH, Apache mod_kerb2 (and mod_auth_ldap for authorization), Active Directory.

1. install server

2. msktutil tool joins machine to domain (simple tool; no dependencies) and now you have /etc/krb5.keytab file

3. minor configuration for base OS -- LDAP using keytab instead of bind user with static password, etc

4. webservers just need an HTTP principal keytab created (simple msktutil command, then extract it from the /etc/krb5.keytab file into a file apache can read/write)

5. I can ssh to every server without a password after running "kinit" on my macbook

6. it just works and it's reliable, time tested, and secure.

feld··on Kill sticky headers (2013)
Clever. Thanks for sharing.
feld··on Ubuntu Systemd Vulnerability
DNSSEC is dead and useless unless every application is written to understand the error messages and every device runs its own DNS resolver (not forwarding, because it's not really validating then and the responses could be spoofed).

We don't need DNSSEC because it doesn't solve any existing problems. The validation is done at the application protocol level with TLS, and apps that aren't running TLS need to fix this gap.

So as it turns out DNSCrypt is winning the internet even though the standards bodies blocked it. Additionally, OpenDNS has massive deployment of DNSCrypt users and this is being furthered by Cisco Umbrella. Cisco is adding this capability to iPhones now as announced earlier this week.

tl;dr DNSSEC has always been DOA, but DNSCrypt is just getting started.

The one and only application I knew of that added DNSSEC for DANE removed it because it was worthless (irssi, irc client).

feld··on Ubuntu Systemd Vulnerability
This has nothing to do with this conversation. DNS recursors are not being discussed. This is strictly about DNS resolvers.

Reader view on iOS Safari makes the web usable on mobile.
feld··on Explain like I’m 5: Kerberos (2013)
All of our linux/freebsd boxes on our network at work must be hooked up to kerberos. most of the day I don't have to type my password for anything HTTP/SSH unless it's for sudo.
feld··on With New Browser Tech, Apple Preserves Privacy and Google Preserves Trackers
User privacy is literally their business model. You pay Apple up front and they never expose your private information to third parties for any reason whatsoever and try to make sure your devices stay private. The cost of your privacy and future software updates through the life of the device is built in to the sticker price. You get exactly what's on the tin.
feld··on After 3072 hours of manipulating BGP, a Nyancat was drawn on this RIPE interface
RIPE is one of the internet registries.
feld··on Live TV on Plex
PlexPass server features are generally just beta release features and not locked to your user account. If you had the URL to the installer for the PlexPass version (which requires no authentication to download), you could have access to this feature without paying them.

But be a good person and pay for PlexPass.

feld··on [dead]
You have to admit he has better release management than 99% of the open source projects out there right now.
feld··on Sprint, SoftBank Said in Informal Deal Talks With T-Mobile
With Sprint gone #4 will be US Cellular which isn't exactly nationwide, but they're growing leaps and bounds.
feld··on Net neutrality is in jeopardy again
I did not evade the point. You are choosing to to ignore it.

This comment is well within HN guidelines.

feld··on Net neutrality is in jeopardy again
Alright let me replay this conversation:

Post:

> the free market is broken. I have a choice between two providers but one is a slight inconvenience for me to have installed so I refuse to use it.

🆒

feld··on Net neutrality is in jeopardy again
It wasn't a personal jeer. I was commenting on his behavior/attitude, not calling him names. There's a big difference.

alternately:

feld··on New in Debian stable Stretch: nftables
OpenBSD's pf doesn't handle layer2.

(imo) Nothing beats FreeBSD's IPFW when it comes to features, but OpenBSD is still king of syntax/usability.

feld··on Password Sharing with Organizations
I think their website is on github, so open a pull request
feld··on TLS verification vulnerability in LibreSSL 2.5.1-2.5.3
Not currently in the plans because the support window for LibreSSL is significantly shorter than a FreeBSD release support cycle.
feld··on Americans' Access to Strong Encryption Is at Risk, an Open Letter to Congress
Bernstein v. United States
feld··on FBI director Comey backs new Feinstein push for decrypt bill
“I don’t think Congress intended that distinction but what it does do us is in our most important investigations it requires us that if we want to find out the subscriber info to a particular email to go and get an order from a federal judge in Washington as part of the FISA court. An incredibly long and difficult process. And I’m worried about that slowing us down — and I’m also worried about it being a disincentive for our investigators to do it at all.”

Hurdles to protect privacy are important. If it's not an arduous process we have a problem.

feld··on Show HN: Kryptonite – a new home for your SSH private key
They certainly seem to have a marketable product for easy ssh key management. They'll make buckets of money on this I bet.
feld··on PfSense 2.5 and AES-NI
What is your definition of cheap? Don't rule out ARM based solutions.
feld··on PfSense 2.5 and AES-NI
Well, if you care about security AES-NI allegedly prevents a side channel attack.
feld··on Mosh v1.3 Released
X Forwarding and TCP Forwarding is also insecure. Not everyone has the same threat model, but for the average person it's a bad idea to do agent Forwarding unless they fully understand the consequences. This doesn't mean the OpenSSH team should remove it.
feld··on Hacker Leaks Episodes from Netflix Show and Threatens Other Networks
Bad security is bad. Nobody should leave ssh open to the internet at large at this point.
feld··on Building a QNX 7 Desktop
But how do you get "accustomed" to it when every OS Cisco has looks the same but is different enough to drive a man insane?
feld··on Building a QNX 7 Desktop
Wow, I forgot that even existed. Here I was thinking of every switch, firewall, and routing product they've done except this line. I guess it doesn't help that I've never had a reason to touch one as every carrier grade router I've used has been Juniper. I wonder why they went with a whole new platform based on QNX when you don't benefit from a realtime OS if all the packets are moved in hardware? Must be something about the pain of upgrades and reloads on other Cisco product lines and somehow QNX can minimize these outage windows.

I've still yet to meet someone who actually prefers Cisco over Juniper MX. I wonder who is buying these?
