小米 sells a small little wifi camera which works quite painlessly.
I’ve bought several over the last few years.

My recent ones don’t work oversea’s though (which is where I install them).
Its extremely bogus selling equipment that is limited to a country, especially when they don’t tell you about it.

Annoying, as my older models aren’t “region locked”, but the newer ones are.

There is a fix for it, although it will likely get more difficult to patch at xiaomi’s whim.
If so, I’ll probably stop buying the camera’s. Lovely how vendors want to mess with customers…

First up, enable telnet on the camera.
Get an SD card or take the card out of the camera.

Create a folder named test on the card.
Create a plain text file called equip_test.sh in that folder, and add the following bash script:


#!/bin/sh
# Telnet
if [ ! -f "/etc/init.d/S88telnet" ]; then
echo "#!/bin/sh" > /etc/init.d/S88telnet
echo "telnetd &" >> /etc/init.d/S88telnet
chmod 755 /etc/init.d/S88telnet
fi
dr=`dirname $0`
# fix bootcycle
mv $dr/equip_test.sh $dr/equip_test.sh.moved
reboot

The script will enable telnet on the camera, and then rename the script so it doesn’t run again on the next boot.

Stick the prepared card into the camera, power on, and it should reboot (twice).
If you check the open ports on the camera ip you should now see port 23 (telnet) is open.

Login with the default user/pass (as below) via telnet

User: root
Password: 1234qwer

Once telnet’d in, enter the following, line by line –

Find and kill the watchdog process

killall watch_process

Find and kill /home/cloud process so we can edit it without the watchdog watch_process restarting it

killall cloud

Change the check within /home/cloud executable to query a fake domain so it never returns a failure, then reboot.


sed -i 's|api.xiaoyi.com/v4/ipc/check_did|api.xiaoyi.foo/v4/ipc/check_did|g' /home/cloud
reboot

Notes – The camera checks for the country by running an executable called /home/cloud
This calls an api at api.xiaoyi.com which does a ip check, then returns a true or false value if it thinks you’re in China or not. We change the /home/cloud executable ip check call to a bad url, which means it can’t perform its check.

Worked on my camera’s running version 1.8.6.1Q_201607271501

We are currently seeing some issues sending TLS encrypted mails to Outlook.com hosted email addresses.
This appears to only be affecting some of the Outlook.com hosted server ip addresses intermittently
213.199.154.87 / mail-db34087.inbound.protection.outlook.com
213.199.154.23 / mail-am14023.inbound.protection.outlook.com

If messages fail to be delivered, you will receive a bounce message similar to the following:

TLS connect failed: timed out; connected to 213.199.154.87.
I’m not going to try again; this message has been in the queue too long.

In the interim we have disabled TLS encryption to the affected addresses.
We are currently unsure if this is a Microsoft issue, or a China Firewall Issue, so this may or may not resolve the issue.

We will update this post when we have further information.

SSL Updates

Flattr this!

The SSL certificate for the all servers have been updated to use a wildcard certificate.

We *finally* changed over to use a wildcard cert, as pricing has come down enough to not warrant having separate certificates per server.
Our new wildcard certificate is valid until 2019.

What does this mean for you?

The bad news
Really old browsers won’t be able to open our site
If you are an XP user running IE6, you won’t be able to load our encrypted sites anymore. We strongly suggest you upgrade though if you fall into that category!
Same goes for those running Android 2.x (which is equally ancient in computer terms).

The good news
Email is now encrypted point to point using AES256 SHA encryption where possible, and webmail is SHA256 encrypted from server to your browser.
Mail servers that support it (i.e. all of ours, plus the major providers like Google, Yahoo etc, will send encrypted mail to our servers).
Mail Headers will include things like the below if encryption is supported –
Received: from usa4.computersolutions.cn (162.210.36.26) by mail.computersolutions.cn with AES256-SHA encrypted SMTP;

Lastly – our new cert gets us a test rating of A at the SSL Labs site.

Despite having friends that have broken limbs skateboarding, I decided to buy myself an Electronic Longboard.
I’m still a kid at heart, despite my ongoing age…

Screen Shot 2015-09-18 at 10.11.00 AM

The board I chose to buy is what looks like a copy of the Boosted Board. The design is different though, but its close enough to look like a copy of sorts. Mine is from a company called BenchWheel out of Hangzhou, and although mildly expensive, isn’t too bad in Electric Skateboard pricing terms, especially in comparison to the similarly specced Boosted board at $1499.

I was originally planning to get the Stary board, as its made in Shanghai, and I was watching their Kickstarter, but sadly they don’t seem to want to sell it locally.
So, I scanned Taobao for similar products, and decided on the BenchWheel, as it looked reasonable quality-wise compared to the other options.

BenchWheel is currently available on Taobao for 2899RMB (about 450$USD odd at this moment in time)

They have 2 models for sale – the B board, which is a standard longboard, and the C board, which is a skinnier board at the ends.

Screen Shot 2015-09-18 at 10.11.45 AM

I bought my BenchWheel on Monday, had it delivered on Wednesday (the magic of Taobao), and have been riding it for a whole 2 days now. I’ve never ridden a skateboard or longboard before, and I’m finding it very easy to ride. I’m already comfortable using it on the road for short trips in light traffic here in Shanghai. Took me about 5 minutes to find my balance, and after about an hour riding around my compound avoiding pedestrians and small rodent sized dogs I felt comfortable enough to take it outside on the street with the bigger traffic.

So far I’m quite happy with it. Top speed is faster than I want to go still, and the battery life is quite decent @ +-20km. The entire bottom length of the board is essentially battery.

Having played with most of the things available here, from e-scooters to airwheel’s, I think a Longboard is the most fun/ practical in daily use, especially for last mile from metro -> home.

All in all, it feels like a decent quality item. The parts are solidly built, and it doesn’t feel like cheap crap.
I haven’t tried a Boosted board or other US brand boards though, so can’t compare to those, but I do know what cheap crap feels like, and this isn’t that.

Some notes on using it
The BenchWheel has a carry handle, but I think there needs to be something smoother around the handle as the sandpaper gets rough.
Its light enough to carry short distances, which is good.

Remote control feels comfortable to use. The speed acceleration is good – its not crazy from stopped, it feels like they ramp up in a curve rather than giving you full throttle immediately. Braking on the other hand feels like they give you too much – you need to be more careful braking as its almost too fast on the controller.

Controller could do with some labelling, there are way too many leds that show different colors (red or green).
The bottom 3 show board battery status. The top two are speed allegedly, although they do flash when the board isn’t sync’d.
The remote and the board time out if not used and left on. The lights stay on, but the remote does nothing. Turning both off then on again resolves that. Looks like it does that when left 3-5 minutes unused. I’ve already hit that once or twice tonight talking to people about the board and not using it for a few minutes, then it doesn’t want to work.

My manual is in Chinese, and the instructions are not very clear – I had initial issues syncing the remote with the board despite reading the instructions, and repeating the steps a couple of times.
Their online support was good (aliwang), and I resolved it, but the manual needs to be much clearer.

I’ve actually had a go at making a better english manual here – http://computersolutions.cn/downloads/benchwheel/

I’ll re-iterate, this is really fun to ride. I’m actually excited to go out and ride around, which is good.
I’ve also been quite lucky in that I haven’t fallen yet. Having a brake and not going too fast helps a lot, as you can just jump off if you feel like falling.

Some tech details

Batteries in a 6S 4P (22.2V nominal @ 6 x 3.7V/ 25V peak/ 20v get off the board before you kill the batteries 😉 ) config using 18650’s @ 8800MAH / 210WH
Wheels are 80x45mm 78A hardness
Board is 920x240x15mm

Whats missing
It feels like a strong version 1.0
That said this is whats missing:

    • Lighting – they need to add underlighting to the board (they actually came out with some the day after I bought mine, grr!, so will be adding mine when it arrives in my next taobao shopping order).
      Carrying handle – great idea, but the board sandpaper surface chafes, so it needs some smoother tape around the handle area.
      Design – There are tons of cool skateboard designs. BenchWheel have completely ignored that and gone with a horridly bad logo font choice and rather basic and bland black board color. This totally needs some work. Luckily you can buy cool stuff on taobao, so thats a fairly easy remedy.
      Packaging – Very white box. Mine actually came slightly damaged, although the board was fine. They need to work on that.
      Battery indicator – The Marbel board has a battery indicator on the board. They need to add something either on the top of the board, or underneath the board with a bar for charge value like you get on electric mopeds and scooters. I might mod mine to add that, as thats fairly easy to do. There is a battery indicator on the remote, but its not too accurate / useful.
      Manual – the existing one isn’t so clear on a few things, even in the Chinese manual.

    Some of our clients are experiencing delivery issues to some domains that use Gmail/Google for their email.

    I previously covered that here – http://www.computersolutions.cn/blog/2015/04/gmail-and-other-google-hosted-mail-delivery-issues/

    The issue is that China is still blocking Gmail/ Google hosted mail, and the recipient domain hasn’t setup their MX records correctly.

    This is fine for servers outside of China, where all of googles mail servers (should) work, but breaks things for those inside China, where only a few servers are reachable.

    Google hosted mail settings are here: https://support.google.com/a/answer/33915?hl=en

    You’ll note that there are 5 different email servers that are listed in priority order.

    Priority Mail Server
    1 ASPMX.L.GOOGLE.COM.
    5 ALT1.ASPMX.L.GOOGLE.COM.
    5 ALT2.ASPMX.L.GOOGLE.COM.
    10 ALT3.ASPMX.L.GOOGLE.COM.
    10 ALT4.ASPMX.L.GOOGLE.COM.

    For mail servers, the higher number is more important, so a priority of 1 will be the first server tried, then the next highest number, and so on.

    If I try to connect to the servers from China.

    telnet ASPMX.L.GOOGLE.COM 25
    Trying 74.125.200.27…
    (times out)

    telnet ALT1.ASPMX.L.GOOGLE.COM 25
    Trying 173.194.72.26…
    (times out)

    telnet ALT2.ASPMX.L.GOOGLE.COM 25
    Trying 74.125.25.26…
    (times out)

    telnet ALT3.ASPMX.L.GOOGLE.COM 25
    Trying 64.233.169.26…
    Connected to ALT3.ASPMX.L.GOOGLE.COM.
    Escape character is ‘^]’.
    (yay, we have a winner!)

    telnet ALT4.ASPMX.L.GOOGLE.COM 25
    Trying 74.125.70.27…
    Connected to ALT4.ASPMX.L.GOOGLE.COM.
    Escape character is ‘^]’.
    (yay, we have a winner!)

    So, we can see that alt3, alt4 work, but none of the others do (as of 9th September 2015 from Shanghai)

    So, some rudimentary testing shows that some servers work, and some do not.
    How does that apply to real world examples.

    Lets look at a non-working domain – ihg.com

    dig mx ihg.com

    ;; ANSWER SECTION:
    ihg.com. 600 IN MX 100 aspmx3.googlemail.com.
    ihg.com. 600 IN MX 50 alt1.aspmx.l.google.com.
    ihg.com. 600 IN MX 50 alt2.aspmx.l.google.com.
    ihg.com. 600 IN MX 100 aspmx2.googlemail.com.
    ihg.com. 600 IN MX 10 aspmx.l.google.com.

    You should easily be able to see 2 things.
    1 – that the MX records are not as per Google settings.
    2 – that the 2 working MX records are not listed.

    This means that while their MX records probably work oversea’s, they will not be deliverable from China. They need to amend their MX records to Googles recommended settings.

    Lets look at another example.

    dig mx rsms-west.com

    ;; ANSWER SECTION:
    rsms-west.com. 6238 IN MX 30 alt2.aspmx.l.google.com.
    rsms-west.com. 6238 IN MX 10 aspmx.l.google.com.
    rsms-west.com. 6238 IN MX 40 aspmx2.googlemail.com.
    rsms-west.com. 6238 IN MX 50 aspmx3.googlemail.com.
    rsms-west.com. 6238 IN MX 20 alt1.aspmx.l.google.com.

    Once again, we can see that the alt3, and alt4 servers are missing, and unfortunately none of the other listed servers are connectable from China.

    Lastly, lets look at a working server

    dig mx teamsequel.com

    teamsequel.com. 12878 IN MX 1 ASPMX.L.GOOGLE.com.
    teamsequel.com. 12878 IN MX 5 ALT1.ASPMX.L.GOOGLE.com.
    teamsequel.com. 12878 IN MX 5 ALT2.ASPMX.L.GOOGLE.com.
    teamsequel.com. 12878 IN MX 10 ALT3.ASPMX.L.GOOGLE.com.
    teamsequel.com. 12878 IN MX 10 ALT4.ASPMX.L.GOOGLE.com.

    You can see that they have the correct Gmail settings as per Gmail / Google settings page, and mail to them is deliverable (as alt3, alt4 are currently not being blocked by the beneficent government of China).

    Unfortunately as this is an issue that is out of our control (MX records are incorrect, and China is being difficult), we cannot mitigate against it. The affected domains will need to amend their MX records appropriately as per the page here- https://support.google.com/a/answer/33915?hl=en.

    I have a couple of older Mac Pro desktops that I tend to.
    As my machines usually get upgraded to the max, they’re still pretty darn useful.
    Currently they’re all Dual Quad Core 3Ghz / 16G Ram 1,1->2,1 flashed, which is more than enough for dev purposes.

    Sadly though, they still have the original graphics cards – rather crappy 7300GT’s.

    One of the issues with the Mac Pro 1,1 is that in Yosemite* the original graphics cards aren’t really supported.

    *Sure Yosemite isn’t really supported either, but it does work after a bit of EFI boot mangling.

    You can work around things, by having a newer NVidia card (i.e. anything 6XX and above), but then you lose boot graphics till the OS loads drivers.

    As I sort of quite need boot graphics due to the bootloader side of things getting borked on occasion, I thought I’d source myself a compatible card.

    There aren’t really that many options unfortunately for vintage equipment, its mostly 8800GT’s that are at least 5 years+, and priced at silly money.

    There are other options though – certain PC graphics cards are usable.

    As a Mac Pro 1,1 (2,1), it needs a card that:
    #1 – Shipped on a Mac Pro 1,1 or 2,1 (so that AMD created an _EBC_ based Mac BIOS).
    #2 – Has a flashable BIOS. This rules out most of the NVidia’s of that era, so its a select number of ATI cards.

    Netkas.org is a good source of reading for that sort of thing.

    ATI 4870 appears to be flashable, and wasn’t too “$$ bills yo!” on Taobao

    So, sourced myself a 4870 1G card (235RMB w/shipping), and set to work.

    There is a wealth of information out there about flashing, but unfortunately all the links appear to be pretty dead.

    The general consensus is to dump the original firmware, then patch it yourself. There are tools for this, but they don’t really work. Cindori’s Zeus et al..

    I tried to do this inside the Mac Pro itself, but it wasn’t having any of it, and didn’t like the perfectly fine DOS USB key(s) I made. Luckily I also had a Windows box available to dump / flash.

    Fun and games with PSU connectors later, I booted off a DOS boot disk, used ATIFlash to dump my original rom, then shutdown again.

    IMG_0068

    Stuck the USB key back in my laptop, used a ROM I found inside Zeus (show package contents, copy the 4870EFI.ROM out) + patch that with my dumped rom using fixrom.py from here – http://forum.netkas.org/index.php/topic,692.0.html and the patch instructions here – http://forums.macrumors.com/threads/race-to-dump-the-4870-rom-whos-first.661681/page-14#post-7297669

    Copied the patched rom back onto the USB, rebooted off again into the DOS boot disk on my Window box, and flashed the new patched EBC rom bios.

    IMG_0069

    A few minutes of recabling later on the Mac, I got a nice boot screen off the card.

    Works fine in OSX too (sleep etc appear to be fine).
    IMG_0070

    As this was a royal pain in the ass, I have the pre-patched rom here – ROM

    Its specifically for the 4870 card I have, so don’t randomly flash to your 4870 card, unless the part number matches. My P/N is below.

    Radeon HD4870 1G Dual DVI
    PN 288-20E85-230AC

    Update

    Google has added another MX (mail server) for Google Hosted mail – alt4.gmail-smtp-in.l.google.com.

    This does not currently appear to be blocked (unlike their other 4 MX servers), so we have removed the forwarding, and mail is transiting normally.


    China has completely blocked gmail hosted mail as of today [28th April 2015]

    This means that all mails heading to google’s servers is now blocked from Chinese ISP’s like ourselves.

    Symptoms will include bounce messages where our server has given up retrying to send out the mail, as the remote server is not accessible over the Chinese internet.

    EG –

    Hi. This is the qmail-send program at mail.computersolutions.cn.
    I’m afraid I wasn’t able to deliver your message to the following addresses.
    This is a permanent error; I’ve given up. Sorry it didn’t work out.

    :
    Sorry, I wasn’t able to establish an SMTP connection. (#4.4.1)
    I’m not going to try again; this message has been in the queue too long.

    In the interim, we have added forwarding for all gmail addressed mail to transit through our oversea’s mail servers in the USA.

    This should solve email delivery issues for gmail addresses – essentially anything addressed to someone @gmail.com

    We are looking at solutions for resolving delivery to other google hosted mail clients, this will take some time to come up with a usable solution. In the interim, we can manually add routes on a server by server basis.

    Be aware that this specific issue is out of our control, and we can only mitigate against it.

    The Mercury MAC1200R (TPLINK WR6300) is one of the cheapest AC based routers on the planet, as I have a few AC devices I thought I’d buy one to try out. They’re available for under RMB120 or so online.

    Mercury hardware is TPLink hardware, albeit using a different name. Same stuff, same factory, different casing.

    The router has 64M ram, and 8M flash. CPU / Wifi AR9344 / QCA9882

    OpenWRT says it has support, so I had a quick go at taking a look at flashing one.

    First steps:

    Open up the unit (remove the 2 screws underneath, then use a spare credit card or similar to jam open the plastic case).

    The serial headers are to the right of the SoC.
    You’ll need a rs232 to ttl or usb to ttl adaptor.

    pl2303

    gnd, tx, rx

    Pin 1 is GND
    Pin 2 is TX (connect to rx)
    Pin 3 is RX (connect to tx)
    Pin 4 is VCC (don’t connect).

    Port speeds are 115200,8,n,1

    Connect up, and you should see a flurry of activity on boot.

    To get into the bootloader (uBoot), you’ll need to type tpl
    May take a few tries, so prepare to pull power and retry again, and again till you get in.

    uboot

    You’ll need a TFTPD server running on 192.168.1.100 to push files over. My Mac no haz ethernet (and Thunderbolt to Ethernet is crud), so I use my venerable X40 and tftpd software.

    It should boot into OpenWRT, you can flash from there.

    I highly recommend replacing the bootloader with an unlocked one.
    i.e. this one – https://github.com/pepe2k/u-boot_mod

    Bootloader sits at 0x9f000000 and is 64kb in size.
    Suggest load in ram at 0x80060000 like they do, and flash from there.

    eg from the bootloader –

    tfpboot 0x80060000 uboot.bin
    erase 0x9f000000 +0x20000
    cp.b 0x80060000 0x9f000000 0x20000

    Pray that it didn’t mess up (or you need an spi flasher…), and reboot!

    Other bits n bobs –

    You’ll need to adjust the opkg.conf file

    ssh into the router @ 192.168.1.1 / root / root

    mv /etc/opkg.conf /etc/opkg.conf.orig

    echo 'dest root /
    dest ram /tmp
    lists_dir ext /var/opkg-lists
    option overlay_root /overlay

    …and install Luci (the openwrt webui)

    opkg update
    opkg install luci

    You should be able to visit http://192.168.1.1 and start changing settings.

    Flattr this!

    While it is the season to be jolly, its also apparently the season for us to move datacenters!

    Our network provider has told us (on rather short notice!) that we need to vacate our current datacentre, and move to a newer larger centre. Its not all bad news though, as it means a chance to refresh equipment, and upgrade services.

    We’ll be moving equipment to a newer Shanghai Telecom datacenter in Waigaoqiao on Saturday 27th December. Most of the work has already been done as we’ve setup new equipment for servers, and tested migrating some clients already.

    Moving servers does mean we will incur some downtime for some clients on Saturday though.
    We will need to change DNS records for you to point to the new location, and migrate some data to new servers.

    We anticipate this taking a few hours.

    Please bear with us while we migrate services on Saturday 27th December.
