pub.client.ftp:login
WmPublic. Connects to a remote FTP server and logs in with a specified user name and password.
Input Parameters
serverhost
String Name or IP address of the FTP server (for example, ftp.netscape.com).
serverport
String Port number on which the FTP server listens for requests (for example, 4566).
The default is 21.
dataport
String Optional. Listener port number of the data transfer channel (for example, 3345).
If you do not specify dataport, the Integration Server will choose the listener port number. This value is used only when the transfertype value is active.
username
String Valid FTP user on the remote FTP server (for example, anonymous).
password
String Optional. Valid password for the FTP user specified in username (for example, someone@somewhere).
account
String Optional. The user name for an account on the FTP server. Specify account if your FTP host requires account information. The account is defined in the FTP protocol to further identify the user that is identified by the username and password input variables.
transfertype
String Type of the FTP data transfer mode (passive or active). The default is active.
encoding
String Optional. Default character set for encoding data transferred during this session. Specify an IANA-registered character set (for example, ISO-8859-1).
If you do not set encoding, the default JVM encoding is used.
serverencoding
String Optional. Specifies the encoding this service uses to convert the incoming FTP command string to encoded bytes that are supported by IANA and the FTP server. If the parameter is null, the service uses the 'UTF-8' character set to encode the FTP command String to bytes.
timeout
String Optional. Time (measured in seconds) to wait for a response from the FTP server before timing out and terminating the request. The default is to wait forever.
secure
Document Indicates whether the FTP session is with a secure FTP server.
Note: Integration Server does not support FTPS (FTP over SSL) requests through FTP proxy.
Key
Description
auth
String The kind of authentication mechanism to use: None, SSL, TLS, or TLS-P.
None specifies that the FTP session is with a non-secure FTP server. This is the default. If the value of auth is None, the securedata variable is ignored.
TLS-P is a shortcut that is equivalent to the sequence AUTH TLS, PBSZ 0, and PROT P. If the value of auth is TLS-P, the securedata variable is ignored.
securedata
String Use the value false for a client sending PROT C (Data Channel Protection Level Clear).
Use the value true for a client sending PROT P (Data Channel Protection Level Private).
Note: If you do not set a value, the default is false.
useJSSE
String Optional. Whether to enable the use of the Java Secure Socket Extension (JSSE) library for creating outbound FTPS connections. Set to:
*yes if the connection requires the use of TLS 1.1 or TLS 1.2. When set to yes, Integration Server creates the connection using the Java Secure Socket Extension (JSSE) library.
*no if the connection does not require support for TLS 1.1 or TLS 1.2. When set to no, the connection supports only SSL 3.0 and TLS 1.0 and Entrust IAIK library is used to create the outbound FTPS connection.
When the value of useJSSE is not specified, Integration Server uses the value set for the watt.net.ssl.client.ftps.useJSSE server configuration parameter.
*A value of yes or no for the useJSSE input parameter overrides the value of the watt.net.ssl.client.ftps.useJSSE server configuration parameter.
*To control the cipher suites used on JSSE sockets that are used while making outbound FTPS requests, set the server configuration property watt.net.jsse.client.enabledCipherSuiteList. For more information, see webMethods Integration Server Administrator’s Guide.
*When using this service to set up an FTPS connection over JSSE with an FTPS server, you must ensure that the FTPS port on the destination Integration Server is configured with the Use JSSE parameter set to Yes. For more information about configuring the FTPS port, see webMethods Integration Server Administrator’s Guide.
newSession
String Optional. Flag indicating whether a a new FTP session will be created for this FTP operation. Set to:
*yes to create a new session for this FTP operation.
*no to use the current session, if one is available, for this FTP operation. This is the default.
clientTimeout
String Optional. Specifies the idle time-out, measured in seconds, for this FTP session. If clientTimeout is set to 0 (zero), the session will never time out. The default is 600 seconds (10 minutes).
proxyAlias
String Optional. Name of the proxy alias for the proxy server through which Integration Server routes the FTP request.
If you do not specify a proxyAlias, Integration Server routes the FTP request through the proxy server specified in the default FTP proxy alias. If there is no default FTP proxy alias, the action taken by Integration Server depends on the value specified for the watt.net.proxy.useNonDefaultProxies parameter.
*If the watt.net.proxy.useNonDefaultProxies parameter is set to true, Integration Server routes the FTP request through the proxy server in any configured FTP proxy alias. If the Integration Server does not have any defined FTP proxy aliases, Integration Server sends the FTP request directly to the FTP server or throws an exception depending on the settings specified for the watt.net.proxy.fallbackToDirectConnection parameter.
*If the watt.net.proxy.useNonDefaultProxies parameter is set to false, Integration Server sends the request to the remote server using a direct connection.
For more information about proxy server usage, refer to webMethods Integration Server Administrator’s Guide.
Output Parameters
sessionkey
String Unique key for the current FTP session. This session key must be provided to execute most other services in pub.client.ftp.
returncode
String Standard FTP protocol return code.
returnmsg
String Standard FTP protocol return message.
logmsg
String FTP log messages for the entire user session.
Usage Notes
If you set the auth variable in the secure parameter to SSL, TLS, or TLS-P, pub.client.ftp:login automatically sends the following sequence of FTP commands prior to sending the USER command:
AUTH <SSL | TLS | TLS-P> PBSZ 0 PROT <P | C>
The client FTP services will not negotiate for less security than you have specified with the auth parameter. However, if you set the auth variable to None, the client FTP services can operate (in a non-secure mode) with any FTP server.
The FTP services will always connect to a secure FTP server using a non-secure (SSL) socket. After getting a valid reply from the AUTH command, the FTP services will convert the connected socket to an SSL socket and initiate SSL handshaking.
