It only takes a minute to sign up. I am trying to establish a logical replica of a database on a remote site.

Therefore we established a permanent VPN connection to that site where we are running two machines. One is an Ubuntu The other one is a Debian 9. I get asked to type in the password and then the connection timesout after about a minute.

When I try to connect from our maintenance box everything works fine. Hosts are pingable and ports are open and listening. I don't have any further ideas what else could cause the client to not connect to a postgres server instance. As said, the connection from another box on the remote site is working. That is a networking problem.

The message and the lack of server log entries prove that you didn't reach the database server. Our IPS Ubiqity Firewall identified this particular connection as a threat and disconnected it every time. Why it identified one client as a threat and not also the other one too, we don't actually know. Sign up to join this community. The best answers are voted up and rise to the top.

The working client is psql PostgreSQL What is the precise error message, both on the client, and from the server's log file? Active Oldest Votes. You'll have to use standard network debugging techniques to solve this problem. Laurenz Albe Laurenz Albe We did by using tcpdump See my last EDIT That log can never belong to that error message: the error message says you could not reach the server, the log says you did, but the client disconnected immediately after connecting.

There is no crash whatsoever, the client just disconnected. Finally solved it! Accepting Laurenz Answer as his first intention was oviously right. Sign up or log in Sign up using Google. Sign up using Facebook.With PostgreSQL, this takes one of the following forms:. The host name of the server. Defaults to localhost. To specify an IPv6 address your must enclose the host parameter with square brackets, for example:. The port number the server is listening on. To do this, you use the DriverManager.

These properties may be specified in either the connection URL or an additional Properties object parameter to DriverManager. The following examples illustrate the use of both methods to establish a SSL connection. If a property is specified both in URL and in Properties object, the value from Properties object is ignored.

The value of this property may contain spaces or other special characters, and it should be properly encoded if provided in the connection URL. Connect using SSL. The server must have been compiled with SSL support.

This property does not need a value associated with it. The mere presence of it specifies a SSL connection. However, for compatibility with future versions, the value "true" is preferred. Setting up the certificates and keys for ssl connection can be tricky see The test documentation for detailed examples.

This value is an optional argument to the constructor of the sslfactory class provided above. Default is prefer. Setting these will necessitate storing the server certificate on the client machine see "Configuring the client" for details. Provide the full path for the certificate file. Note: This parameter is ignored when using PKCS keys, since in that case the certificate is also retrieved from the same keyfile.

PKCS key files are only recognized if they have the ". If your key has a password, provide it using the sslpassword connection parameter described below.

Otherwise, you can add the flag -nocrypt to the above command to prevent the driver from requesting a password.

It only takes a minute to sign up. Could this be some sort of PostgreSQL server configuration which limits timeouts and ignores my client settings?

Abort any statement that takes more than the specified number of milliseconds, starting from the time the command arrives at the server from the client. A value of zero the default turns this off. Terminate any session with an open transaction that has been idle for longer than the specified duration in milliseconds. This allows any locks held by that session to be released and the connection slot to be reused; it also allows tuples visible only to this transaction to be vacuumed.

See Section Not out of the box. It would be pretty easy to compile a custom server that ignored your settings, though.

But much more likely is that your connections are being severed by a firewall or gateway that doesn't like idle connections. If you have access to the server's log file, that should give a good clue.

If the client says the server closed the connection unexpectedly, and the server says the client closed the connection unexpectedly, then it is probably something in between the client and the server which is actually severing the connection.

Alternatively, input can be from a file. In addition, it provides a number of meta-commands and various shell-like features to facilitate writing scripts and automating a wide variety of tasks.

Print all nonempty input lines to standard output as they are read. This does not apply to lines read interactively. This is equivalent to setting the variable ECHO to all. Specifies that psql is to execute one command string, commandand then exit. This is useful in shell scripts. Thus you cannot mix SQL and psql meta-commands with this option. This is different from the behavior when the same string is fed to psql 's standard input.

Also, only the result of the last SQL command is returned. Because of these legacy behaviors, putting more than one command in the -c string often has unexpected results. It's better to feed multiple commands to psql 's standard input, either using echo as illustrated above, or via a shell here-document, for example:.

Specifies the name of the database to connect to. This is equivalent to specifying dbname as the first non-option argument on the command line. See Section Copy all SQL commands sent to the server to standard output as well.

This is equivalent to setting the variable ECHO to queries. You can use this to study psql 's internal operations. Use the file filename as the source of commands instead of reading commands interactively. After the file is processed, psql terminates. Note however that Readline is not used in this case much as if -n had been specified. In general, both will do what you expect, but using -f enables some nice features such as error messages with line numbers.

There is also a slight chance that using this option will reduce the start-up overhead. On the other hand, the variant using the shell's input redirection is in theory guaranteed to yield exactly the same output you would have received had you entered everything by hand. Use separator as the field separator for unaligned output. Specifies the host name of the machine on which the server is running.

If the value begins with a slash, it is used as the directory for the Unix-domain socket. Turn on HTML tabular output. List all available databases, then exit.By using our site, you acknowledge that you have read and understand our Cookie PolicyPrivacy Policyand our Terms of Service.

After configuring my environment variables, I now have it where psql logs me on my preferred database and table. However, while I'm exploring several of tables in it, I'd like to have a statement timeout of around a minute. I don't have access to the server configuration nor would I want to change it.

Are there any nice solutions to this problem, or am I always doomed to set the timeout manually for each interactive session? You could use your.
