71街

前阵子忽然发现在国外假设的vpn在家无法访问https网站了，检查了路由什么的都正常，遂怀疑是小区宽带的防火墙作祟，不了了之。

今儿晚上又仔细分析了下，会不会是前阵子换了无线路由器的原因呢？以前也遇到过nat功能没打开导致vpn无法连接的问题，于是登陆到路由器管理平台，发现有个转发规则栏目，进入后，打开“特殊应用程序”，有如下文字提示：

某些程序需要多条连接，如Internet游戏，视频会议，网络电话等。由于防火墙的存在，这些程序无法在简单的NAT 路由下工作。特殊应用程序使得某些这样的应用程序能够在NAT路由下工作。

看来很大可能就是它的问题了，添加一个条目：

其中1723是pptp协议要使用的端口。

断开电脑网络，重新连接，发现问题得到解决。

后来重启了电脑，发现又不行了，捯饬了半天，原来是路由器MTU数的问题，改成1490，重启路由，搞定。

不知道不觉中，本站使用的VPS已经三年多了，这三年不管从服务还是稳定性都比较满意。前文(http://www.71j.cn/archives/250)已经做过推荐了，忍不住再推荐下：

前文介绍了针对Cisco AnyConnect VPN在win8和mac系统下的连接方法，但有朋友反馈说在mac系统下的软件安装后无法使用。遂奉上@virtman 大师的linux通用方法。

首先安装openconnect

$ sudo yum install openconnect   (在Fedora上，会顺带安装：vpnc-script.noarch，这个包会被openconnect用到)

$ sudo openconnect –script /etc/vpnc/vpnc-script https://your-vpn-server.com

Attempting to connect to 121.0.29.22:443

Got CONNECT response: HTTP/1.1 200 OK
CSTP connected. DPD 30, Keepalive 20
Connected tun0 as 10.1.25.155, using SSL

至此，连接成功。ctrl+z然后bg置入后台运行即可。

在godaddy上续费域名，发现居然有支付宝的支付方式，很开心的选择了他，却不不幸的失败了，本以为可能有延迟，等一会儿订单就会被确认，结果等了一天也不行。遂给godaddy提ticket，回复如下:
Thank you for your response. I see you need assistance with an order placed through Alipay.

When you place an order with us using international payment options, they can take up to 30 days to provide payment confirmation (though it’s typically less than 24 hours). While we wait for payment confirmation, we track it as a Pending Order. This means products you order are not immediately available. However, when we receive payment confirmation, we attempt to fulfill the products and services in your Pending Order.

Domain names and other services are not registered or fulfilled until we receive payment confirmation. In the interim, someone else can register domain names in your Pending Order, causing your registration to fail and that portion of your order to be canceled. However, we will fulfill and charge you for any other services from your Pending Order.

意思就是让我等，最多可能要30天。这太不靠谱了，于是又回复他们，让快点确认，他们回复说不行，只能等，我说等不了，退款吧，他们说不行，等30天后才能退。我勒个去，就这样来回邮件了9天，依然没动静。我终于忍不了了，于是取消了pending的订单，结果钱没退我。只好再发他们邮件:
I called Alipay again, they said the fund is still on your account. If you are not going to give my money back, they will help me take the judicial process to prosecute you.

I don’t believe Godaddy is so irresponsibility. Please just have a check to see how many times I have contacted you for this order. You really disappointed me.

Additionally, if the order is canceled, your funds should be once again available in AliPay. However, please note that we cannot cancel a pending order, and we apologize for any inconvenience this may cause you.
