Q. How do I get an account on the ECMWF computer system?

A. All OpenIFS users will be given full access to this website. Access to other ECMWF systems may not always be required and your needs should be discussed with the OpenIFS team or User Support. Member state users should always apply for an account via their national Met Service representative. A contact list can be found here: http://www.ecmwf.int/services/computing/help/reps/index.html. If you want to contact ECMWF prior to applying to your national Met Service then please see this list for the appropriate ECMWF User Support contact to ask: http://www.ecmwf.int/services/computing/help/User_Support_Contact_Points.html

If you are a user from a non ECMWF member state you should contact openifs-support@ecmwf.int to discuss your needs.

Q. I can't retrieve files from the ECMWF ftp server. I get an error: ftp:bind: Address already in use.

A. This is usually caused by a firewall at the user site blocking ftp connections. There are two types of ftp connections, so-called 'active' and 'passive'. The essential difference is that 'active' mode tries to open multiple connections to the ECMWF ftp server. This behaviour is undesirable for sites running firewalls and is usually blocked. Although passive mode ftp is usually the default, if you see this error try using the '-p' option 'ftp -p' or, if it's available the command 'pftp' which invokes a passive mode only ftp.
