Schwab Web Site Doesn’t Like Arm / Linux Firefox

How very odd.

It used to work. Now it doesn’t.

Trying to log onto https://www.schwab.com from my Raspberry Pi or Odroid XU4 fails to even open a window. Just hangs with a blank screen.

I have no idea why.

It does work with FireFox on the Mac, but it is running an older FireFox as it can’t take updates anymore. I don’t have other browsers on the Linux boxes, well, at least none that I’d say works… so can’t really debug it more than that. I’ve also logged on via the tablet in the past, so it does work with Android browsers and on an ARM based CPU.

Why would it suddenly stop working? (Well, really, stopped about 2 months ago, but I figured the next update would “fix” it. It didn’t.)

The Mac is running through the same routers and all, so not a network thing. It’s got to be something specific to Firefox on Linux (or on these particular flavors of Linux. One Devuan the other Armbian).

I suppose sometime “later” I’ll try booting up an old Ubuntu or Red Hat Pi image and see if they work. I don’t really want to swap platforms for that one use, but I can easily have a “dedicated Schwab trading chip”.

I do wonder about the timing as it is right in sync with the FireFox “upgrades” to deal with Meltdown and Specter bugs. I did notice some familiar pages loading and running a bit slower on the XU4 than prior to the “fix”.

Ah well.

FWIW, the Birthday Bash brought to me 2 more SBCs. My cluster is now made up of 2 x Pi M2, 2 x Pi M3, 2 x Orange Pi One, and an Odroid C1. (I’ve moved the XU4 over to desktop useage, but it can join the cluster if desired). I’ve spent the last couple of days rearranging the desk and getting the cluster bits all together. I still need to clean up the network a bit. Found my old Netgear 8 port switch, but not the power brick. It’s in a box… somewhere… so eventually I’ll have that 100 Mb switch in place. For now, I stuck an old hub on the Netgear Router as a port addition.

So that’s basically 16 cores of Pi, 8 of Orange, and 4 of Odroid (with an additional 8 if desired). Total of 28 in the basic config and 36 “all up”.

I presently have most of it warming up on Boinc, but the two newest boards are not playing well with it yet. I’ve consulted my old Boinc posting, but there’s still something not quite right. They all communicate, but the Boinc Manager isn’t talking to them. Most likely one of those config / permissions settings things. I also need to finish the install / configure of “distcc” on the new members, then try some big build on it.

At this point, I have more computes than I’m presently able to effectively use. Guess it’s time to get back at that parallel FORTRAN and Models project ;-) and that learning Julia… I’d use them to mine crypto-coins but their small core size makes it kind of silly and I’m just not really “into” the whole digital currency thing anyway. Besides, the whole field has moved off to dedicated ASIC / hardware land. I’d be mining with a teaspoon while everyone else was using power shovels and blasters.

Well, that’s the status update on the cluster stuff for now. Back to debugging, configuring, and testing things.

    At first I thought the timing on that sounds like it matches up with when Firefox dropped support for Java. Looking at the link below, that appears to have happened in march of 2017 so a bit longer but might be something similar.

    https://www.cso.com.au/article/615493/firefox-52-drops-java-plugin-support-expands-http-secure-warnings/

    What version fire fox are you running?

    https://news.slashdot.org/story/18/02/02/156222/firefox-59-will-stop-websites-snooping-on-where-youve-just-been

    If it is that tracking block this link has a fix

    https://support.mozilla.org/en-US/questions/1201834

  2. For me, on an old Ubuntu box where the Firefox is over a year old, the page loads but keeps on loading “getting data from p.ispot.tv”, so could be the setting is to not show until you’ve got all the data. Or maybe that .tv link is buggering things anyway.

  3. E.M.Smith says:

    Well, got Boinc running on the two new boards. It was the “let stations manage me” setting. To quote myself:

    “HOWEVER, until the IP number of the management station was put in the remote_hosts.cfg file on the headless nodes, it would not allow the connection…”

    chiefio@PiM3RedBox:~ $ cat /etc/boinc-client/remote_hosts.cfg 
    # This file contains a list of hostnames or IP addresses (one per line)
    # of remote hosts, that are allowed to connect and to control the local
    # BOINC core client via GUI RPCs.
    # Lines beginning with a # or a ; are treated like comments and will be
    # ignored.
    #
    #host.example.com
    #192.168.0.180
    10.1.1.123
    192.1.1.123
    

    Since the “floater” might be on either network, I’ve put both numbers in the list.

    The boinc daemon seems to be still crashing on the headend box, so something is still amiss with it. Oddly, it has the management station on it and that is still working fine.

    But I’ve proven all the nodes can see each other and be managed. Now to just put more interesting things on them ;-)

    @Larry:

    52.5.0 32 bit Firefox ESR / ARMv7

    So more likely the Java plug in. I know it’s 48? or some such on the Mac. Given that it takes some fair time for things like FireFox updates to make it from FireFox to The Linux Community to Debian to ARM to Devuan… it likely just got to me recently…

    It’s a place to start looking, anyway.

    @Simon:

    Well, I did a DNS lookup on that site and it was found, so my DNS isn’t blocking it. As it loads on the Mac, it isn’t causing any issues there either.

    Maybe I need to find what other “real” browsers are available on the Pi / Devuan / Debian family…

    Or maybe this is why it just showed up:

    https://www.cso.com.au/article/615493/firefox-52-drops-java-plugin-support-expands-http-secure-warnings/

    “Firefox ESR continues to support Silverlight and Java and will do so until early 2018 to help users who need the plugins. ”

    It’s now “early 2018″…

    I’d expect the Schwab web site to work with all the OTHER browsers that already dumped java API support; but it may be they had / have some kind of “sniff it’s butt and if it’s ESR keep using Java” and there’s just not enough of us to show up on their support call board…

    I’ll try a chip swap to an older Firefox later tonight and see if that’s enlightening…

    I wonder if there’s a way to tell FireFox to spoof the identity string and claim it’s not ESR…

    Yup:

    https://www.howtogeek.com/113439/how-to-change-your-browsers-user-agent-without-installing-any-extensions/

    UPDATE: Well, tried several from Mozilla 5.0 to FireFox–Mac to FireFox to Internet Explore 10 and Safari… whatever. Nothing changed.

    Might try palemoon it is a firefox fork – they have a linux port

    There used to be a bunch of websites that would not work with my Ubuntu Linux including Citicards.

    Over the years I see fewer problems so that now Bank of America gives me an error message “Unsupported Browser” but works perfectly!

  8. beng135 says:

    I just used Firefox 49.0 on puppy linux & it worked on the Schwab site.

  9. E.M.Smith says:

    @Beng135:

    Thanks! That tends to confirm that it’s something in the 52 and newer that’s changed. I remembered it working on this computer in the not that distant past…

    One of the advantages of a bunch of cheap computers. You just slide over one keyboard and keep on going…

  10. beng135 says:

    Just as an aside, I notice using precise puppy 5.7.1 that the video sharpness is VERY good — noticeably better than win10. I can especially see it on sat views in google maps. Display hardware info says the openGL renderer is “Gallium 0.4 on AMD RV710”, ver 2.1 Mesa 8.0.4

  11. E.M.Smith says:

    I always liked Puppy ;-)

  12. Larry Ledwick says:

    Another possibility for sudden loss of access to some features might be this DRM content control stuff.

    https://support.mozilla.org/en-US/kb/enable-drm?as=u&utm_source=inproduct

  13. E.M.Smith says:

    Interesting idea, but I don’t think that’s it. The Schwab page doesn’t load At All, not just some video failing to play. It’s just the top page advert / identity page with login. So I think it’s something else than DRM stuff. In any case, not real worried about it. I have other platforms that work fine.

    I had similar problems. This page helped:

    Specifically try, preferences -> Privacy -> Use custom settings for history -> cookies: “Show cookies”
    Then delete all cookies that start with the name, “Schwab”.
