Re: Problem with the conection

Also may want to set 255.255.255.255/0 trust and then test access. I
found that this seems to allow access from anywhere and then maybe tie
it down.

Subject: Re: [ADMIN] Problem with the conection

try adding these few lines:
host database user 161.0.0.0/8 md5
host database user 161.0.0.0/8 trust
# "local" is for Unix domain socket connections only
local all all trust

make sure other "public" 161.x.x.x ip cannot access your server because
i don't think 161.x.x.x is a private subnet.

I have problem with the conection to my database postgres.
I have no problem with the conection in my server (150.xxx.xxx.xxx) and
in
the computers with ip near my server. For example if my server
ip is 150.111.111.111 I can connect with 150.111.111.222 or
150.111.111.113

I connect using the following code:
try{
Class.forName("org.postgresql.Driver").newInstance();
return
DriverManager.getConnection("jdbc:postgresql://150.xxx.xxx.xxx/database?
charSet=LATIN1",
user,password);
}
catch(ClassNotFoundException e){
}

The problem happens when I try to connect with the java program to my
server in a computer with 161.x.x.x ip.
In the log file I find this message.

In the computer with ip 161.xxx.xxx.xxx they open port 5432 (for using
postgres) and I include this lines in the pg_hba.conf file

host database user 150.111.111.111 255.255.255.255
trust
host database user 150.111.111.222 255.255.255.255
trust
host database user 161.xxx.xxx.xxx 255.255.255.255
trust

Can someone help me with this problem?
Thanks.
