Run commands in Synology

1. Download cloudflareddns.sh from this repository to /usr/local/sbin/cloudflaredns.sh

wget https://raw.githubusercontent.com/joshuaavalon/SynologyCloudflareDDNS/master/cloudflareddns.sh -O /usr/local/sbin/cloudflaredns.sh

If you put the script in other name or path, make sure you use the right path.

2. Give others execute permission

chmod +x /usr/local/sbin/cloudflaredns.sh

3. Add cloudflareddns.sh to Synology

cat >> /etc.defaults/ddns_provider.conf << 'EOF'
[Cloudflare]
        modulepath=/usr/local/sbin/cloudflaredns.sh
        queryurl=https://www.cloudflare.com/
EOF

queryurl does not matter because we are going to use our script but it is needed.

Get Cloudflare parameters

1. Go to your domain overview page and get the Zone ID.
2. Go to your account setting page and get API Key.
3. Get record id using Cloudflare API.

curl -s GET "https://api.cloudflare.com/client/v4/zones/[Zone ID]/dns_records" \
	-H "X-Auth-Email: [Email]" \
	-H "X-Auth-Key: [API Key" \
	-H "Content-Type: application/json" \
	| jq '.result[] | {name, id, zone_id, zone_name, content, type}'

You need to replace with [] with your parameter. Then, you get the id in result which is you Record ID.

1. Enter the parameters to the cloudflareddns.sh.
2. Login to your DSM
3. Go to Control Panel > External Access > DDNS > Add

Till now, there is no official iOS app to add/manage torrent tasks of TransmissionBT. The only working application is iControlbits which is available to Jailbroken iOS users.
So there is not much choice left for non-jailbroken users to manage Tranmission tasks. We can use Safari web browser to view and delete the downloading task but no way to add torrent file as iOS has a very strictly privilege control on file dealing. It is impossible to download a torrent file and upload it via Safari browser.

话说前不久为了在ebay上买一台mint拖地机，新注册了个美国ebay的账号。和其他美国购物网站一样，地址、电话当然写的是转运公司的仓储地址。然后就是绑定已经用了很久很久的paypal付钱，收货。卖家很不错，还给了好评。没想到刚买第二天商品就跌价，发了封站内信给卖家，卖家二话不说就把差价打到我paypal了。非常愉快的购物经历。

过了一周，货还没到转运公司呢，却收到了ebay的邮件，MC999，我的ebay账号因为安全原因被无限制禁止了。 Continue reading “奇葩的ebay”
