pptp always ignoring localip on Ubuntu

Posted on by

I don’t know how the other various linux distros handle this but I found this by accident:

Nov 17 12:04:25 ukweb pppd[4943]: Using interface ppp0
Nov 17 12:04:25 ukweb pppd[4943]: Connect: ppp0 <--> /dev/pts/0

Nov 17 12:05:28 ukweb systemd-networkd[592]: ppp0: Link DOWN
Nov 17 12:05:28 ukweb systemd-networkd[592]: ppp0: Lost carrier

With the emphasis on “local IP address 192.168.0.1”. Which is *NOT* in my config. I went as far as adding a bridge to satisfy the proxy arp! Netplan is some yaml thing and yeah not a big fan.

    ethernets:
        eth0:
            addresses:
            - PUBLICIP/24
            gateway4: GATEWAY
            match:
                macaddress: AA:BB:CC:00:00:01
            nameservers:
                addresses:
                - 1.1.1.1
                - 8.8.8.8
    bridges:
      br0:
        dhcp4: no
        addresses: [192.168.23.1/24]
    version: 2

my /etc/ppp/pptpd.conf had the options set, but no matter what it *ALWAYS* went to 192.168.0.1

option /etc/ppp/pptpd-options
logwtmp
localip 192.168.24.1
remoteip 192.168.23.30-250

And then I found it after doing what i should have done, and grep around to find out that pptpd.conf should actually live in /etc

Yeah that’s right, there is 2 of them although they should be the same. A symlink and a restart later, and now I get this:

Nov 17 12:19:56 ukweb kernel: [  112.718861] PPP MPPE Compression module registered
Nov 17 12:19:56 ukweb pppd[1002]: MPPE 128-bit stateless compression enabled
Nov 17 12:19:58 ukweb systemd-networkd[599]: ppp0: Link UP
Nov 17 12:19:58 ukweb systemd-networkd[599]: ppp0: Gained carrier
Nov 17 12:19:58 ukweb pppd[1002]: found interface br0 for proxy arp
Nov 17 12:19:58 ukweb pppd[1002]: local  IP address 192.168.23.1
Nov 17 12:19:58 ukweb pppd[1002]: remote IP address 192.168.23.10

MUCH much better. I don’t know if this is anything worth wriging about, but if I can save someone else an hour of wondering why the config isn’t working and why their pptp is always defaulting to 192.168.0.1 and why it’s wreaking havoc with any default home router, where here it is.

Ruffle the Flash feathers!

The End of the World!

So it’s the END OF THE WORLD, and sadly that means that all the old media of the 1st gen ‘rich’ web experence is all gone with the long end of Adobe flash. At one point Flash was not only ubiquitious but all sponsored a C/C++ compiler but that stuff sadly won’t work.

So yeah, sad. However, check out ruffle! Naturally it’s a chromium extension, but everything is chrome now so it’ll work fine. It plays many of the early flash type stuff with little to no issues!

Currently Ruffle only supports games written in ActionScript 1 and 2. This includes all games before 2006 and only some games released later.

Unfortunately, your content was using Actionscript 3, which Ruffle does not yet support.

From the FAQ

It’s hard to think it’s been over 20 years since the whole ‘eStudio‘ thing, but it’s cute to keep it going. Although we are at the point where you can run Windows 2000 in javascript so there is that brute force path…

So sure it’s not perfect but what is? Kitty Cat Dance, Dancing Colin, Maiyahi, it’s a MAD WORLD!!

Web Rendering Proxy (WRP) 4.5.2

Posted on by

(This is a guest post by Antoni Sawicki aka Tenox)

Pleased to announce WRP version 4.5.2. This is just a bug fix release however it also contains two frequently requested features:

UI customization via HTML template file. This has been requested by many users and it makes total sense. To use it download wrp.html from github, place in the same directory as wrp binary and edit to your liking. WRP will load built-in version if file is not present.

This should enable easy development of more modern UI for never browsers. Potentially with JS and CSS. Please send PR if you make something!

Second most frequently asked feature – re-capture (retake?) of a screenshot without page reload. For example if the page did not capture correctly or if something is changing on the page.

I have also updated Docker Hub and gcr.io repos.

Sun IPX using WRP at VCF West

As usual please test and report bugs!

The next update will focus on issues with page size, viewport and rendering full length pages (h=0) which is currently very broken.

How not to write a web scraping engine

Seriously, the sad thing is that they wasted all their time, and bandwidth. The good thing is that PHP7 is far better at this, than PHP5. I know it’s not hipster neaveaux but PHP7 is really awesome stuff.

I didn’t wake up to a million messages about being down, rather a look at what was going on showed me this:

Obviously something is up.

I checked Cloudflare:

All those hits, and no change in user traffic. So I’m not popular.

And it’s all from the United States. Going back to WordPress I can see it’s mostly from one user!

A look through the 30MB log, and it’s a broken site scrape

This is just terrible you are quoting the link to the link, having slashes going every which way. What the heck!? Don’t be a jerk, pace the thing, why are you trying to DOS it? While my hosting is clearly not robust, why can’t you wait a few seconds between each query? Also look at the output and URL’s it’s sending it’ll never work!

Oh and speaking of WTF:

There is no comment on that page. There never was. Look I know it sucks he’s dead, but there is nothing you or me can do about it.

Digital.com purges DIGITAL

Posted on by

while finally getting around to renaming aux to aux_ for my AltaVista based search engine, I noticed that the product link, http://www.altavista.software.digital.com/search/index.htm, is suddenly not found.

Well isn’t that a shame.

Ironically in a twist of fate, I found this article, “AltaVista Search Engine History Lesson For Internet Nerds“, with a nice overview of the amazing rise, and tragic neglectful decline of AltaVista. Then what struck me was this line:

Digital was the original owner of the domain that you’re reading now; www.digital.com. 

Wait!? What?!

Did digital.com just purge DIGITAL’s history?

Now I feel like an idiot for not having archived the archive. Always in motion is the past, it’s a shame that DEC’s pages had to be destroyed. History in digital form, especially Digital’s is always in motion and subject to $CURRENT_YEAR.

Sad.

Web Rendering Proxy – Full Page Scrolling

Posted on by

(This is a guest post by Antoni Sawicki aka Tenox)

Due to a popular demand I have added an option of generating full page height screenshot and allowing client browser to do the scrolling.

This makes the browsing experience much smoother, you have resources for it. Beware, a full page screenshot can be several MB in size encoded as gif/png and much more as a decoded raw bitmap on the client. I managed to crash Mosaic and OmniWeb a few times. Fortunately typical Wikipedia page is under 1 MB so for most part is should be fine. To activate just put 0 in page Height.

I have drafted a pre-release on github for testing. Please let me know any feedback. I’m also thinking whether enable this by default, or not.

December 14th, the end of Yahoo! groups

Oddly enough these things have been going on since 2001, and have been curated gardens instead of the mess that is usenet (which is still operational!), or private mailing lists.

The 2 that Im on are the Hercules 390 group which moved to group.io. While other groups like H390-music (MUSIC/SP the Canadian mainframe OS with internet hooks) that sadly died along with it’s author, is probably going to be purged from the internet.

Along with other things like pdos, or even the board game Supremacy.

I don’t know what the answer is, other than to always have downloadable mailing list archives, and never trust a single place. So much stuff is deleted to save trivial amounts of space, and neither corporations nor government institutions can be trusted to maintain anything.

Thankfully there is archive.org, but who backs them up?

Confessions of a paranoid DEC Engineer: Robert Supnik talks about the great Dungeon heist!

What an incredible adventure!

Apparently this was all recorded in 2017, and just now released.

It’s very long, but I would still highly recommend watching the full thing.

Bob goes into detail about the rise of the integrated circuit versions of the PDP-11 & VAX processors, the challenges of how Digital was spiraling out of control, and how he was the one that not only championed the Alpha, but had to make the difficult decisions that if the Alpha succeeded that many people were now out of a job, and many directions had to be closed off.

He goes into great detail how the Alpha was basically out maneuvered politically and how the PC business had not only dragged them down by management not embracing the Alpha but how trying to pull a quick one on Intel led to their demise.

Also of interest was his time in research witnessing the untapped possibilities of AltaVista, and how Compaq had bogged it down, and ceded the market to the upstart Google, the inability to launch a portable MP3 player (Although to be fair the iPod wasn’t first to market by a long shot, it was the best user experience by far).

What was also interesting was his last job, working at Unisys and getting them out of the legacy mainframe hardware business and into emulation on x86, along with the lesson that if you can run your engine in primary CPU cache it’s insanely fast (in GCC land -Os is better than -O9).

The most significant part towards the end of course is where he ‘rewinds’ his story to go into his interest in simulations, and of course how he started SIMH when he had some idle time in the early 90’s. SIMH of course has done an incredible amount of work to preserve computing history of many early computers. He also touches on working with the Warren’s TUHS to get Unix v0 up and running on a simulated PDP-7 and what would have been a challenge in the day using an obscure Burroughs disk & controller modified from the PDP-9.

Yes it’s 6 hours long! But really it’s great!

WRP 4.0 Preview

Posted on by

(This is a guest post from Antoni Sawicki aka Tenox)

Welcome a completely new and absolutely insane mode of Web Rendering Proxy. ISMAP on steroids!

While v3.0 was largely just a port from Python/Webkit to GoLang/Chromedp, the new version is a whole new game. Previously WRP worked by walking the DOM and making a clickable imagemap out of <A HREF> nodes. Version 4.0 works by using x,y coordinates obtained from ISMAP to perform a simulated mouse click in Chrome browser. This way you can click on any element of the page. From annoying cookie warnings, to various drop down menus and even play some online games. Also pagination has been replaced with a clickable scroll bar.

Enough talking, you can watch this video:

Or download the new version and try it yourself!

Please report bugs on github.com. Thank you!
