ECaccess Tools (ECTools) - The ECaccess Tools gives Member States (in the following
"Member States" (MS) includes "Co-operating States") and other ECMWF users batch access to
the ECMWF computing and archiving facilities for the management of files, file transfers
and jobs. Access is available via the Internet as well as via RMDCN.


ECaccess Certificate
Using the ECaccess Tools requires a valid ECaccess Certificate.

The ECaccess Certificate is a standard X509 digital Certificate saved on the user's
computer as a file. It identifies a user to the ECaccess Gateway. The ECaccess
Certification Authority (ECCA) signs each Certificate. Therefore, when a user provides his
Certificate to the gateway, its signature is checked using the ECCA public key for

The ECaccess certificate is by default valid for 7 days for all services.

The ECaccess Tools are also available at ECMWF. As you have already been validated to
enter ECMWF, you will not need a Certificate when using these ECaccess shell commands

Creating a Certificate
The ECaccess Certificate must be stored in the "$HOME/.eccert.crt" file and can be created
with one of the following method (both methods requires an ECMWF user identifier and token

Using the "ecaccess-certificate-create" command:

Please refer to the man page of the command for more details.

Using the Web interface:

Login to the Web server and in the menu click the "Get Certificate" option to download the
new ECaccess Certificate.


When accessing FILEs at ECMWF through the ECtools, the following domains are available:

HOME: the $HOME directory (home:)
SCRATCH: the $SCRATCH directory (scratch:)
ECFS: the ECFS directory (ec:)
ECTMP: the ECTMP directory (ectmp:)
HOST: any server at ECMWF ({host-name}:)

The format of the path is the following: "[domain:][/user-id/]path"

If no user-id is specified then the current user-id is selected by default. The user-id
parameter is not valid with the HOST domain.

If no domain is specified then an absolute path will translate to an absolute path on the
ecgate server and a relative path will translate to a path in the HOME directory of the
current user.

"bin/a.out" a.out file in the $HOME/bin directory of the current user
"home:bin/a.out" a.out file in the $HOME/bin directory of the current user
"/tmp/a.out" a.out file in the /tmp directory on ecgate
"home:/xyz/bin/a.out" a.out file in the $HOME/bin directory of user xyz
"ec:bin/a.out" a.out file in the ECFS bin directory of the current user
"ec:/xyz/bin/a.out" a.out file in the ECFS bin directory of user xyz
"c1a:/c1a/tmp/systems/xyz/a.out" a.out file in the /c1a/tmp/systems/xyz/ directory of c1a

In the DESCRIPTION section you will find the FILEs commands which can be used to manage
the files at ECMWF. Whenever a parameter or an option refer to an ECaccess File then the
"[domain:][/user-id/]path" syntax apply.


ECtrans refers to unattended file transfers initiated from ECMWF.

ECtrans allows transfering files between ECMWF and remote sites. Like the UNIX "rcp"
command, ECtrans requires no password to be specified on the command line for the remote
host: the ECaccess gateway performs the security checking. Unlike standard FTP, ECtrans is
suitable for unattended file transfers in scripts, cron jobs, etc., as it avoids the
problems inherent in storing passwords in text files and sending passwords across

Even if you don't have a local gateway installed, you can benefit from ECtrans by using
the ECMWF ECaccess gateway. Please note that in this case the transfer is not as secured
as when a Member State ECaccess gateway is used.

Target location
Users who wish to transfer files between ECMWF and Member State servers need to declare
one or more remote Member State users (msuser association) for the storage/retrieval of
the remote file. This can be done through the ECaccess Web interface of the target
gateway. For every "msuser" declaration, the hostname and the login username and password
need to be specified.

After the ECaccess gateway installation, the Member State ECaccess system administrator
can customise the access methods for file transfers. These will be displayed through the
ECaccess Web interface. Several schemes can be implemented, such as:

1 - The target directory for a particular destination is a sub-directory of a central
directory configured by the administrator, with the sub-directory name matching the msuser
name. 2 - The target directory for all file transfers to a given destination is a sub-
directory of the msusers home directory. The administrator configures the sub-directory
name. 3 - The target directory for a given destination is configurable by the user. The
administrator determines whether or not the user is allowed to include ".." in the
directory path.

Target directories can be located on:

1 - Member State servers running a standard FTP service accessible from the ECaccess
gateway. This is known as a "genericFtp" destination and is the most convenient way of
getting the files to the system you want, under the specified user ID. 2 - The server
running the ECaccess gateway. This is known as a "genericFile" destination. All users will
share in a common directory the files transferred using this destination. 3 - Member
State servers running a proprietary application. The administrator provides ectrans with
the implementation of the access protocol. The administrator can also use more complex
rules to define special target locations for ECMWF users, Member State users or groups of
Member State users. The command "ectinfo" described in the next section can be used to get
the translated URL of a target location, giving a Member State user identifier and a
destination name (passwords are displayed as ***).

In the DESCRIPTION section you will find the ECtrans Association and Transfer Management
commands which can be used to manage the ECtrans Associations and associated Transfers.


ECMWF maintains some notifications (events) which are linked to ECMWF's operational
activity and offers the service for time-critical jobs. This service is also available to
MS users who maintain their own notifications and can therefore create simple dependencies
between different activities, at ECMWF and remote sites.

In the DESCRIPTION section you will find the Events Management commands which can be used
to manage such Events.


The ECaccess Tools are organized under nine categories covering access to the whole
computing and archiving facilities of ECMWF. Each command is documented with its own man
page which provide explanation as well as examples on how to use it.

The following options are common to all the ECtools:

-help Print a brief help message and exits.

-manual Prints the manual page and exits.

-retry count
Number of SSL connection retries per 5s to ECMWF. This parameter only apply to the
initial SSL connection initiated by the command to the ECMWF server. It does not
apply to all the subsequent requests made afteward as it is mainly targeting
errors that can happen from time to time during the SSL handshake. Default is no

-debug Display the SOAP and SSL messages exchanged.
