撤掉防火墙改为直连，WINDOWS的IP改为 172.16.110.70/24 没有任何问题。故判断是防火墙的问题。
防火墙策略全开 允许UNTRUNT 到TRUNT ANY 结果还是不行。

XPath OR operator for different nodes
...
Logical operators (OR, XOR, AND) are the same in every programming language but natural language interprets them slightly different. It's best to remove ambiguity when discussing issues related to them. Furthermore, with XPath it's best not to thin...
Best practices for overriding isEqual: and hash
...
A simple XOR over the hash values of critical properties is sufficient
99% of the time.
For example:
- (NSUInteger)hash
{
return [self.name hash] ^ [self.data hash];
}

What is the fastest way to compare two sets in Java?
...like that? Well if the set hashcode was:
zero for an empty set, and
the XOR of all of the element hashcodes for a non-empty set,
then you could cheaply update the set's cached hashcode each time you added or removed an element. In both cases, you simply XOR the element's hashcode with the curr...
