SSH改善ftp速度

Hostmonster是可以开启SSH的，只是需要传给他们一个身份证明复印件。去他们的帮助搜索了一下SSH，发现有篇文章很有意思。讲的是如果ftp传输很差劲经常卡死在0Kb/s，这样的情况可能是由于严格的firewall规则引起的。这种情况通常发生在某些ISP传输数据的时候有些不必要的数据包转发。这种情况可以通过Secure ftp来解决。里面还推荐了一款免费软件：FileZilla.
回想我在学校里管理bluehost空间的时候就经常发生ftp卡死的情况，很郁闷。很可能就是因为这种情况而导致的，因为在学校上网必须使用校内的透明代理。这下可好了，有了Secure ftp，大概就可以解决这个问题了，而且这样的传输更加安全，避免了“中间人攻击”这种情况。想到这些，立即去照了张护照照片来申请SSH权限。

原文如下：
“To protect our users, our firewall is very restricted. With some Internet Service Providers, data packets are slightly altered in the ISPs routing and our firewall does not recognize it as a valid connection which is why your ftp connection slows down. To eliminate this problem you can use Secure FTP. To use Secure FTP, you must apply for SSH access by submitting a government issued photo id to our support center making sure to include your domain name.

A free ftp client that will handle Secure FTP is Filezilla. You can download it from filezilla.sourceforge.net

Now launch Filezilla and the following will walk you through how to setup a Secure FTP connection

1. First go to File...then Site Manager
2. Then click the New Site button
3. Give your new connection a name and select the Host field on the right and type in your domain name
4. Select the Server type dropdown box
5. Select the SFTP using SSH2 option. Remember that this option is ONLY going to work if you have applied for and received SSH access from our support center.
6. Then select the Normal option for the Logon type
7. Select the User field and type in your ftp username
8. Then click the Connect button
9. Type in your password and then click the OK button
10. It will now let you connect using Secure FTP. Just upload your files like you would as normal. When you need to connect again, just go to the Site Manager in Filezilla and choose the appropiate connection ”
里面详细的讲解了如何使用FileZilla去进行Secure ftp传输。供需要的朋友做参照，也方便我将来回头再看。呵呵
