could not connect to server: Connection refused Is the server running on host "192.168.1.11" and accepting TCP/IP connections on port 5432?
It's on my network and I know I have to edit pg_hba.config file. 它在我的网络上,我知道我必须编辑pg_hba.config文件。 Everywhere I read, I have to add a line, 我到处阅读,我必须加一行,
host all all ip address/mask md5
My question is, what is the /mask and how/where do I get it? 我的问题是,什么是/ mask?如何/在哪里获得? The IP I'm connecting from is 192.168.1.9. 我连接的IP是192.168.1.9。
Thank you so much for your time, I am using Ubuntu 16.04 and Postgresql 9.4. 非常感谢您的宝贵时间,我使用的是Ubuntu 16.04和Postgresql 9.4。
The number after the /
is actually not a mask, but the CIDR mask length. /
后面的数字实际上不是掩码,而是CIDR掩码长度。
It states how many leading bits must match the IP address preceeding the /
for an incoming address to match the pg_hba.conf
entry. 它指出要与pg_hba.conf
条目匹配的传入地址,必须有多少个前导位必须与/
之前的IP地址匹配。
If you want the line to only work for your host, use 192.168.1.9/32
(all 32 bits must match). 如果您希望该线路仅适用于您的主机,请使用192.168.1.9/32
(所有32位必须匹配)。
To have the line apply to all hosts that start with 192.168.1.

To match all hosts, use 0.0.0.0/0
