bandwagonhost vps,  我装了个扶墙,  默认SSH port,
后来商家发email ，说将我SSH port  改成另外的万位数值port。
xshell 上去  ,   SSH port  我改成千位数值port，正常使用.

vps的速度，设成 千位数值SSH port 是不是比  万位数值SSH port  要快？

应该没关系

foxconndmd

和端口有什么关系，除非有按端口做QOS。

SSH 单线程  太慢了 还是 SS快

cmse

根本没关系。只与网络有关

简单的方法就是查看日志：cat /var/log/auth.log
以下的日志是不是表示有坏人198.x.x.6 在频繁扫描我的vps ssh port?

没有关系 改端口是为了防止批量扫描这是用单车和自行车的区别
