Project

Description

Information about the project is now available in the project description.

You can find a small Java class for a password dialog or a connection dialog here. The Java example from the lecture is available here.

Database Clients

To access the database you can either use the web interface as described below, a graphical frontend (like pgadmin) or you can use a local client (psql). How to obtain such a local client depends on the operating system:

• Linux:
  If psql is not available on your linux system, tell the administrator or use the package manager to install it. Make sure it is able to connect to the server (which runs 8.3).
• Mac OS X
  You can download the full PostgreSQL package from PostgreSQL.org. Note that this gives you both the server and the client. You might want to switch off the server if you are using the course's remote server.
• Windows:
  There is a client-only package available from PostgreSQL Frontend for Windows.
  Alternatively, you can download the full PostgreSQL package from PostgreSQL.org. Note that this gives you both the server and the client. You might want to switch off the server if you are using the course's remote server.

Access to the Database

Accounts for the database server have been distributed during today's exercise. If you do not have an account yet, please contact me as soon as possible. You should be able to access your account from the IMADA terminal room or the IMADA notebook network using a local client (e.g. psql -h 10.110.4.210 -U dbusername dbusername) and the address 10.110.4.210. The administration interface is available at http://10.110.4.210/phppgadmin/.

The server is not directly accessible from outside IMADA, but you can use an SSH tunnel:

ssh -L 5432:10.110.4.210:5432 loginname@logon4.imada.sdu.dk

Then you can access the database server with a local client (e.g. psql -U dbusername dbusername) as localhost.

If you need to access the administrative web server, just type:

ssh -L 8080:10.110.4.210:80 loginnname@logon4.imada.sdu.dk

Then you can access the web server as http://localhost:8080/phppgadmin/.

You can also have it more comfortable by putting the following lines into ~/.ssh/config:

Host puma-db
User loginname
HostName logon3.imada.sdu.dk
LocalForward 5432 10.110.4.210:5432

Host puma-web
User loginname
HostName logon3.imada.sdu.dk
LocalForward 8080 10.110.4.210:80

In case you are using Windows, you can use the program plink to set up the tunnels:

plink.exe -L 5432:10.110.4.210:5432 loginname@logon4.imada.sdu.dk
plink.exe -L 8080:10.110.4.210:80 loginnname@logon4.imada.sdu.dk
