Flattr this!

One of the (not so) fun things about China is that almost everything needs to be licenced.
As part of the China bureaucracy plan, all forms of wheeled transport in Shanghai require a licence (yes, even bicycles!).

Riding motorized transport without one is not recommended, as this can lead to fines, deportation, and jail in worst case scenario’s.
This has been documented enough times by those unfortunate enough to knowingly break the law.

Electric Bikes/ Scooters are not exempt from requiring a licence, despite what the nice man at the shop selling you the bike, or others might say.

To be street legal in Shanghai, you need a plate.

1) Only bikes purchased in Shanghai can get a Shanghai plate.
Keep your official receipt (fapiao) when you buy the bike, as it needs to be used to get your licence.

2) As of a law passed in April 2008, Shanghai Electric bikes have to be:

* Under 40kg.
* Not capable of speeds faster than 20km/hr.
Effectively this means only bikes < 36v. * Listed in the allowed vehicle database for Shanghai. Legal bikes have a 15 digit unicode (like a car VIN) which is unique. Manufacturers have to apply for a production licence for this, and not all have done so. A list of licenced manufacturers is available here: http://www.shbicycle.com/Article/ShowArticle.asp?ArticleID=6230

If you own a bike that is older than that date that does not conform to the above, and you had a legal licence at that time, then it can be renewed each year, and its still legal.

3) To licence an electric bike/scooter/moped you need to visit the police station for your district.

You will need to bring:

* – The fapiao for the bike
* – Valid form of ID (Passport for foreigners)
* – The bike
* – Money to pay for the licence (11rmb currently)

FAQ’s:

Can I use a legal plate from another province?
eg Jiangsu…
Possibly No, with some caveats –
It is not legal to ride with an out of town plate unless it is a weekend, or public holiday. You can be fined 200RMB if caught riding outside of these times, although this is unlikely. This is a grey area though, so police attitude to this may vary/change. While having a plate is better than not having a plate, it may not help if you have an accident.

Can I carry a passenger?
According to the law, no.

Is is illegal to drive without a plate?
Yes. Being a foreigner does not exclude you from following the law.

Do I need a driving licence for an electric bike/moped/scooter?
No.

Is there an official list of legal bikes?
There are 2 official sites where you can check if a bike is legal – http://www.shbicycle.com and http:/www.shjtaq.com

A current list of legal bikes with photo’s is here:
http://www.shbicycle.com/Photo/ShowClass.asp?ClassID=84

You will need Chinese reading abilities to read either site.

Instructions below for non illiterate:

市民在购买电动自行车时,可以通过上海市自行车行业协会网站上(HTTP://WWW.SHBICYCLE.COM),或上海交通安全信息网(网址: HTTP://WWW.SHJTAQ.COM,点击首页右上方的 “车/牌/证公告”栏目中的“上海电动自行车—上牌备案登记表”)查询该目录。

Are the cool Vespa lookalikes legal?
No.
The Vespa lookalikes / Spicy Motors bikes are not street legal for various reasons – weight, voltage, speed (unless you have a 2008 model licenced prior to 8/2008).
Additionally, they are not listed in the police database of allowed models.

…but XXX / Bike shop / my friend etc says its legal?
In short: They’re lying.

Caveats:
If you are in living a city other than Shanghai this may be ok.
Different cities, different rules.
If the bike is 2nd hand, and has an existing legal Shanghai licence, and it has been renewed each year, then it is also ok (albeit extremely unlikely).
Otherwise, see the short answer.

What about repair / warranty?
By Law, bikes have a “三包” (threefold warranty).

If you have issues within 7 days the seller is legally obligated to give your money back if you so wish.
Within 2 weeks, you are guaranteed a replacement bike.
Within 1 year, if you have more than 2 of the same type of failure, they have to replace, or you can get your money back less depreciation.
Consumables such as lights are not covered by this, nor are collisions..

Parts have the following warranties (by law):
Motor: 2 years
Frame, Fork, Charger, Controller, Battery: 1 year

*For batteries, failure is deemed as holding < 60% of original charge. More details here: http://www.shbicycle.com/news/ShowArticle.asp?ArticleID=43

Note that it is while it is illegal for shops to sell bikes that cannot be licensed, many still do.

Flattr this!

[Update 23/Oct/09: Hotmail has fixed this issue now]

Our logs were showing lots of repeated send failures from Hotmail.
A closer investigation of the issue has revealed that Hotmail has suddenly decided that the mail RFC’s are too good for them to follow.

RFC’s are the standards which define how things work. When people don’t follow the standards, this makes things break.

In this case, it meant that all mail from Hotmail was being rejected, this is a Hotmail is broken issue!
Getting Hotmail to change their broken setup is likely to be non-productive – there are already a few pages of complaints about it on their site, complete with the boilerplate totally useless replies from drones who don’t understand the issue, despite it being helpfully spelled out for them.

See here –
http://windowslivehelp.com/community/p/127432/474962.aspx
http://windowslivehelp.com/community/t/123986.aspx

Unfortunately, while bouncing invalid email content is correct from a technical perspective, our clients need to be able to receive mail from Hotmail.
As an interim solution, I’ve patched qmail to allow for bare linefeeds.

This was fairly easy – a small patch to qmail-smtpd.c, a recompile, then restart qmail-smtpd.

To patch, look for switch(state) in qmail-smtpd.c, and remove the straynewline(); calls, so that barelinefeeds are accepted.
Code to change below:

case 0:
if (ch == '\n') { state = 1; break; }
if (ch == '\r') { state = 4; continue; }
break;
case 1: /* \r\n */
if (ch == '.') { state = 2; continue; }
if (ch == '\r') { state = 4; continue; }
if (ch != '\n') state = 0;
break;
case 2: /* \r\n + . */
if (ch == '\n') return;
if (ch == '\r') { state = 3; continue; }
state = 0;
break;

As the Wiki for fail2ban is a little less than explanatory than it could be (and they reversed my edits which made the instructions clearer), here are my own notes on setting up fail2ban to block pop3 attacks.

Have been seeing sample dictionary attacks on some servers for a while now from random ip addresses – eg

Sep 28 13:01:03 www vpopmail[20410]: vchkpw-pop3: vpopmail user not found www@:24.153.205.71
Sep 28 13:01:03 www vpopmail[20411]: vchkpw-pop3: vpopmail user not found web@:24.153.205.71
Sep 28 13:01:09 www vpopmail[20417]: vchkpw-pop3: vpopmail user not found web@:24.153.205.71
Sep 28 13:01:11 www vpopmail[20420]: vchkpw-pop3: vpopmail user not found web@:24.153.205.71

Annoying, but not realistically going to provide much of a security issue – most of the user names are the generic ones which aren’t actually in use on the servers.

As we already use fail2ban to perform basic service blocks against naughty script kiddie wannabee’s, why not have it block vpopmail attacks also.

Our mail error logs are located in /var/log/mail.log

As you saw above, the logs show the same common text for each failed login –

vchkpw-pop3: vpopmail user not found web@:24.153.205.71

A simple regex to identify that in the logs would look like this (as per the fail2ban wiki)

failregex = vchkpw-pop3: vpopmail user not found .*@:$

First step is to create a filter for fail2ban.

Create /etc/fail2ban/filter.d/vpopmail.conf as below:

# Fail2Ban configuration file for vpopmail
#
# Author: Lawrence Sheed
#
# $Revision: 1.0 $
#

[Definition]

# Option: failregex
# Notes.: regex to match the password failures messages in the logfile.
# Values: TEXT
#
failregex = vchkpw-pop3: vpopmail user not found .*@:$

# Option:  ignoreregex
# Notes.:  regex to ignore. If this regex matches, the line is ignored.
# Values:  TEXT
#
ignoreregex = 

Second step is to add our filter to the fail2ban setup

Add this to the bottom of /etc/fail2ban/jail.conf

[vpopmail]
enabled = true
port    = pop3
filter  = vpopmail  
logpath = /var/log/mail.log
maxretry = 3

logpath should be amended to whatever your mail logs for vpopmail appear.
maxretry should be set to a value that you agree with.

Restart fail2ban with a: /etc/init.d/fail2ban restart
and check that it has added the filter.

tail /var/log/fail2ban.log

You should see a line like this:

2009-10-01 12:36:09,590 fail2ban.jail   : INFO   Jail 'vpopmail' started

If so, you’re all set!


Some additional tips, as I have found some issues subsequently in Fail2ban on some systems:

If you find that fail2ban gives error 200 or 400 on occasion, this is due to a timing issue bug in fail2ban.
There are 2 possible solutions:

Solution 1 – Edit fail2ban

Open /usr/bin/fail2ban-client

Look for

def __processCmd(self, cmd, showRet = True):
beautifier = Beautifier() for c in cmd:

After for c in cmd: add a delay
time.sleep(0.5)

This should look similar to this now –

def __processCmd(self, cmd, showRet = True):
beautifier = Beautifier() for c in cmd:
time.sleep(0.5)

Save, and restart fail2ban. If you still see 200 or 400 issues, increase the delay higher e.g. time.sleep(0.8)

Solution 2 – Use a different block method

Instead of iptables, we can configure fail2ban to use route

Add a config file for this:

pico /etc/fail2ban/action.d/route.conf

Add this into the file and save it.

# Fail2Ban configuration file
[Definition]
actionban = ip route add unreachable 
actionunban = ip route del unreachable 

Open /etc/fail2ban/jail.conf

Look for ban action = … in the [DEFAULT] section, and comment it out with a # at the start of the line
then add
eg

#banaction = iptables
banaction = route

Save the file.
Restart fail2ban

It will now use route to block bad ip’s.
