Hi
IIB Version 10.0.0.13
Windows 2016 Server Standard
I can connect successfully to an external sftp server using WinSCP from our production server. The server breaks out of our network through a firewall.
I've create the logon credentials for the IIBNode (using a private key file) as follows:
mqsisetdbparms IIBNode -n sftp::SFTPLogin_ELRVRE -u ELRVRE -i rsa_live
The connections sometimes succeeds via the broker but often fails as per the logs below:

2021-11-25 20:14:22.321716 5536 Error BIP3380E: File node ''FTP/RMB/From - PROD - ELRVRE'' in message flow ''ISOPain.MSF_ISOPain_AutomaticClearingBureau_FTP_Transfer'' could not connect to remote ''SFTP'' server ''196.00.000.00''. Reason: ''timeout(20000): Session.connect: java.net.SocketTimeoutException: Read timed out'.'
The FileInput or FileOutput node failed to open a connection to a remote server. Possible reasons for this failure are that the server could not be contacted, the initial FTP protocol was not observed, or an error situation exists at the server. The reason text is from the detected connection failure.
Ensure that:
- The server address is correct and is locally resolved to a valid IP address.
- The server port is correctly specified (the default port for FTP is 21, and for SFTP it is port 22).
- A firewall does not block access to the remote server.
If you adjust an FtpServer configurable service definition, restart the integration node to pick up the new settings. For more information, see the "FtpServer configurable service properties" topic in the IBM Integration Bus information center.

Could the timeout of 20000 perhaps be the problem? If so, how do I increase the timeout for sftp::SFTPLogin_ELRVRE or for the IIBNode?

Thank you in advance for any assistance.

hi...assuming you are using the 'FTP server' config service you can use 'timeoutSec' to change the default 20sec timeout value.
https://www.ibm.com/docs/en/integration-bus/10.0?topic=properties-ftpserver-configurable-service
Before changing the timeout value it is worth getting the FTP server team to investigate why the connect attempts are taking this long...we had a similar scenario where the server had multiple copies of our public certificates saved to their truststore which was delaying the connection attempts...so it is worth tracing the connection and see. |
