VPN directly on a host

All past VPN usage was inside containers & virtual machines, but problems with doing that behind wifi led to dedicating a host to a VPN.  The journey begins with installing a new raspberry pi.  

dd if=image of=block device bs=4096 status=progress

 Edit /etc/passwd & delete the root password to allow a root login without password.  They don't support the pi user anymore.  Then from the serial console, disable some services.

 

 systemctl disable lightdm

systemctl disable cups

 systemctl disable ModemManager

 systemctl disable NetworkManager

 systemctl disable wpa_supplicant

Reboot it

 To enable public wifi on it, you need to log in on a browser.  iptables is not included in the image.  sshd, firefox, & chromium do come with the image.  sshd_config needs the PermitRootLogin yes line.  Firefox is broken but chromium can log in with a lot of prodding.  Then you can install iptables & bypass the X11 forwarding.

The next step is following the lion kingdom's container document to install the VPN bits directly on the host.

Then, with no mtu adjustments it started downloading pretty quickly.  So transmission-daemon needs to run in a dedicated box with no container & probably no masquerading.  

 The downloads go in /var/lib/transmission-daemon/downloads & they're super slow to access over NFS.  Reliable gigabit is the other big challenge.  Then there's a permanent enclosure for the server farm.



They're all going to standard standoffs & acrylic sheets but they're really hard to access. 

There's no current need for the extra complexity of masquerading on anything with its own wifi, but we're definitely back to the age of dedicated boxes being required for a lot of things.

Maybe it would work in a virtual machine, but the memory is just too expensive & modern operating systems are too dependent on direct hardware.

It's still just a hope that wifi will be more reliable than wired connections to Comca$t.  The whole affair made lions ponder how much Comca$t is costing the world with its reliability problems.  Just 1 outage is immensely devastating.

Another idea that came up was trying dhclient from a different MAC address, but something longer term was needed.

 All the DNS lookups on public wifi are in the clear.  It's not ideal, but nothing useful can be done with DNS lookups.

 


In the end, an ad hoc server farm was the best strategy.  The new 5V drop & permanent home took a full night.   

Putting sin on the floor reduced the cable run.  The phone wifi & gateway should be combined in a xena replacement.  That should get the piano's 64GB for gootube downloads.  Concurrent AP & station is a reasonable compromise for saving on cables & for the amount lions use phone wifi.  The cables are a big deal.  Then piano goes to a 32GB for just recording audio.  About time to scrap the fake starlink enclosure & go to an exposed vertical panel, maybe a bare MDF panel.

As messy as it is, this same operation 25 years ago would have entailed an apartment full of PC towers & they wouldn't have had nearly the resources.  The 1st single board 486 & how expensive it was is still fresh in lion minds.  It was really unheard of until 2000.



Did not know they embedded the host name in their IPv6 address.

Haven't seen Uncle Buck in at least 30 years, but it's still as vivid as it was originally.  It's a very easy one to download.  

There was no recording from TV, but it might have been on all the time.  Don't have many memories of TV consumption from 2000-2008.  It was always on in the background but manely the midnight CNBC talkshow or channel surfing.  Most of those years were spent on the road.

    It was time to take on the lion kingdom's 1st 1 star movie. It honestly wasn't as bad as the Dictator, Bedazzled, Monty Python.  Most of the hate was from comparing it to the classic.  Visuals were good for animals who are into castles.  Wonder Heroine as the villain was a good twist.  It was bat shit boring.  Tedious jobs like dialog writing are all automated now & that's definitely not as bad as other movies.  Automated 3D model generation has made modern visuals very lavish.  If only that level of detail could be done in realtime for VR goggles.    Zegler was back from her previous engagement in district 12.   The mane redeeming factor for lions was evil Wonder Heroine.     & finally the Joan of Arc scene everyone hated.    & the ending just fizzled.  It seems they're trying to depart from the physicality of past heroine warriors & make them more like housewives.  It's h...

  The lunar eclipse situation. Diced tomato spagetti 2.  Plain noodles shining through the diced tomatos, meatballs, oregano, pepper, & cheese still has what it takes.  It's better than watered down sauces with tiny bits of meat. ---------------------------------------------------------------------------------------------------------- Once again pondered if the S & P is another Nikkei 225. The nikkei is back where it last collapsed, 40 years ago, with a similar rate of increase in the last 25% but slower in the preceding years.  Maybe the index fund play has worn out or maybe it hasn't. Both the S&P & the Nikkei doubled in the last 5 years.  -------------------------------------------------------------------------------------------------------

 Finally tracked down the Sun bootloader font from many decades ago & put it in Cinelerra as gallant12x22.  Put Sun Gallant Demi into the goog to get useful results. https://github.com/dim13/gallant/tree/master/ttf   It's a fixed point font in an archaic format.  Some guy converted it into a TTF with a lot of antialiasing.  He has a PNG image showing no antialiasing.  It has to be set to size 22 & requires a threshold to get rid of the antialiasing.  Freetype might be shifting it 1/2 pixel vertically. It had a kind of curiosity value, but lions have had no need for any fixed point fonts besides the 24pt Sony of CAEDM fame. Another hit said it was 1 of the fonts available in kernel framebuffer mode.  Lions haven't used kernel framebuffer mode in decades.  It could possibly replace 24pt Sony if lions wrote a fixed point converter. As for the other Sun lore, there's some potato cam footage of the Sun flight simulator, Aviator.  You ...
