`Server Dialog`:index:
|
|
**********************
|
|
|
|
Use the *Server* dialog to describe a connection to a server. Note: you must
|
|
ensure that the pg_hba.conf file of the server from which you are connecting
|
|
allows connections from the host of the client.
|

|
|
:align: center
|
|
|
|
Use the fields in the *General* tab to identify the server:
|
|
|
|
* Use the *Name* field to add a descriptive name for the server; the name
|
|
specified will be displayed in the *Browser* tree control.
|
|
* Use the drop-down list box in the *Server group* field to select the parent
|
|
node for the server; the server will be displayed in the *Browser* tree
|
|
control within the specified group.
|
|
* Use the color-picker in the *Background* field to specify the background
|
|
color for the server.
|
|
* Use the color-picker in the *Foreground* field to specify the foreground
|
|
color for the server.
|
|
* If the *Connect now?* checkbox is checked, the client will attempt a
|
|
connection to the server upon completion of the dialog; this is the default
|
|
* Provide a comment about the server in the *Comments* field.
|
|
|
|
Click the *Connection* tab to continue.

|
|
Use the fields in the *Connection* tab to configure a connection:
|
|
|
|
* Specify the IP address of the server host, or the fully qualified domain
|
|
name in the *Host name/address* field. If you provide a unix domain socket,
|
|
the directory name must begin with a "/".
|
|
* Enter the listener port number of the server host in the *Port* field. The
|
|
default is *5432*.
|
|
* Use the *Maintenance database* field to specify the name of the initial
|
|
database to which the client will connect. If you will be using pgAgent or
|
|
adminpack objects, the pgAgent schema and adminpack objects should be
|
|
installed on that database.
|
|
* Use the *Username* field to specify the name of a role that will be used when
|
|
authenticating with the server.
|
|
* Use the *Password* field to provide a password that will be supplied when
|
|
authenticating with the server.
|
|
* Check the box next to *Save password?* to instruct pgAdmin to save the
|
|
password for future use. Use
|
|
:ref:`Clear Saved Password <clear_saved_passwords>` to remove the saved
|
|
password.
|
|
* Use the *Role* field to specify the name of a role that has privileges that
|
|
will be conveyed to the client after authentication with the server. This
|
|
selection allows you to connect as one role, and then assume the permissions
|
|
of this specified role after the connection is established. Note that the
|
|
connecting role must be a member of the role specified.
|
|
* Use the *Service* field to specify the service name. For more information,
|
|
see
|
|
`Section 33.16 of the Postgres documentation <https://www.postgresql.org/docs/current/libpq-pgservice.html>`_.
|
|
|
|
Click the *SSL* tab to continue.
|
|
|
|
.. image:: images/server_ssl.png
|
|
:alt: Server dialog ssl tab
|
|
:align: center
|
|
|
|
Use the fields in the *SSL* tab to configure SSL:
|
|
|
|
* Use the drop-down list box in the *SSL* field to select the type of SSL
|
|
connection the server should use. For more information about using SSL
|
|
encryption, see
|
|
`Section 33.18 of the Postgres documentation <https://www.postgresql.org/docs/current/libpq-ssl.html>`_.
|
|
|
|
If pgAdmin is installed in Server mode (the default mode), you can use the
|
|
platform-specific File manager dialog to upload files that support SSL
|
|
encryption to the server. To access the File manager dialog, click the
|
|
icon that is located to the right of each of the following fields.
|
|
|
|
* Use the *Client certificate* field to specify the file containing the client
|
|
SSL certificate. This file will replace the default
|
|
*~/.postgresql/postgresql.crt* if pgAdmin is installed in Desktop mode, and
|
|
*<STORAGE_DIR>/<USERNAME>/.postgresql/postgresql.crt* if pgAdmin is installed
|
|
in Web mode. This parameter is ignored if an SSL connection is not made.
|
|
* Use the *Client certificate key* field to specify the file containing the
|
|
secret key used for the client certificate. This file will replace the
|
|
default *~/.postgresql/postgresql.key* if pgAdmin is installed in Desktop
|
|
mode, and *<STORAGE_DIR>/<USERNAME>/.postgresql/postgresql.key* if pgAdmin
|
|
is installed in Web mode. This parameter is ignored if an SSL connection is
|
|
not made.
|
|
* Use the *Root certificate* field to specify the file containing the SSL
|
|
certificate authority. This file will replace the default
|
|
*~/.postgresql/root.crt*. This parameter is ignored if an SSL connection is
|
|
not made.
|
|
* Use the *Certificate revocation list* field to specify the file containing
|
|
the SSL certificate revocation list. This list will replace the default list,
|
|
found in *~/.postgresql/root.crl*. This parameter is ignored if an SSL
|
|
connection is not made.
|
|
* When *SSL compression?* is set to *True*, data sent over SSL connections will
|
|
be compressed. The default value is *False* (compression is disabled). This
|
|
parameter is ignored if an SSL connection is not made.
|
|
|
|
.. warning:: In Server mode, certificates, private keys, and the revocation list
|
|
are stored in the per-user file storage area on the server, which is owned
|
|
by the user account under which the pgAdmin server process is run. This
|
|
means that administrators of the server may be able to access those files;
|
|
appropriate caution should be taken before choosing to use this feature.
|
|
|
|
Click the *SSH Tunnel* tab to continue.
|
|
|
|
.. image:: images/server_ssh_tunnel.png
|
|
:alt: Server dialog ssh tunnel tab
|
|
:align: center
|
|
|
|
Use the fields in the *SSH Tunnel* tab to configure SSH Tunneling:
|
|
|
|
You can use the "SSH Tunnel" tab to connect pgAdmin (through an intermediary
|
|
proxy host) to a server that resides on a network to which the client may
|
|
not be able to connect directly.
|
|
|
|
* Set "Use SSH tunneling" to *Yes* to specify that pgAdmin should use an SSH
|
|
tunnel when connecting to the specified server.
|
|
* Specify the name or IP address of the SSH host (through which client
|
|
connections will be forwarded) in the *Tunnel host* field.
|
|
* Specify the port of the SSH host (through which client connections will be
|
|
forwarded) in the *Tunnel port* field.
|
|
* Specify the name of a user with login privileges for the SSH host in the
|
|
*Username* field.
|
|
* Specify the type of authentication that will be used when connecting to the
|
|
SSH host in the *Authentication* field:
|
|
|
|
* Select the *Password* option to specify that pgAdmin will use a password
|
|
for authentication to the SSH host. This is the default.
|
|
* Select the *Identity file* to specify that pgAdmin will use a private key
|
|
file when connecting.
|
|
|
|
* If the SSH host is expecting a private key file for authentication, use the
|
|
*Identity file* field to specify the location of the key file.
|
|
* If the SSH host is expecting a password of the user name or an identity file
|
|
if being used, use the *Password* field to specify the password.
|
|
* Check the box next to *Save password?* to instruct pgAdmin to save the
|
|
password for future use. Use
|
|
:ref:`Clear SSH Tunnel Password <clear_saved_passwords>` to remove the saved
|
|
password.
|
|
|
|
|
|
Click the *Advanced* tab to continue.
|
|
|
|
.. image:: images/server_advanced.png
|
|
:alt: Server dialog advanced tab
|
|
:align: center
|
|
|
|
Use the fields in the *Advanced* tab to configure a connection:
|
|
|
|
* Specify the IP address of the server host in the *Host address* field. Using
|
|
this field to specify the host IP address may save time by avoiding a DNS
|
|
lookup on connection, but it may be useful to specify both a host name and
|
|
address when using Kerberos, GSSAPI, or SSPI authentication methods, as well
|
|
as for verify-full SSL certificate verification.
|
|
* Use the *DB restriction* field to provide a SQL restriction that will be used
|
|
against the pg_database table to limit the databases that you see. For
|
|
example, you might enter: *live_db test_db* so that only live_db and test_db
|
|
are shown in the pgAdmin browser. Separate entries with a comma or tab as you
|
|
type.
|
|
* Use the *Password File* field to specify the location of a password file
|
|
(.pgpass). A .pgpass file allows a user to login without providing a password
|
|
when they connect. For more information, see
|
|
`Section 33.15 of the Postgres documentation <https://www.postgresql.org/docs/current/libpq-pgpass.html>`_.
|
|
* Use the *Connection timeout* field to specify the maximum wait for connection,
|
|
in seconds. Zero or not specified means wait indefinitely. It is not
|
|
recommended to use a timeout of less than 2 seconds. By default it is set to
|
|
10 seconds.
|
|
|
|
.. note:: The password file option is only supported when pgAdmin is using libpq
|
|
v10.0 or later to connect to the server.
|
|
|
|
* Click the *Save* button to save your work.
|
|
* Click the *Cancel* button to exit without saving your work.
|
|
* Click the *Reset* button to return the values specified on the Server dialog
|
|
to their original condition.
