tFTP + Socket Is Not Established

Tim_Ouimet — Fri, 15 Nov 2024 21:48:01 GMT

Hello - a bit stumped on this one.

On development box - job performs correctly as designed.

On Production box - job throws error.

"Exception in component tFTPConnection_1 (OraclePunchDeliveryErrors)

com.jcraft.jsch.JSchException: timeout: socket is not established

at com.jcraft.jsch.Util.createSocket(Util.java:394)"

The FTP connection on the same box using WINScp or Filezilla - with the same private key(s) - connects using all the same connection details. Not sure what else may be afoot.

Any insights - if you've run into this in the past - would love to know.

Thanks!

Hello @Tim Ouimet ,

Regarding to the error log, seems it can not connect to the sftp server due to network issue.

Could you please check the firewall rule of sftp server to whitelist the ip of the production box machine?

Best regards

@Aiming Chen Ended up finding a resolution to this.

The issue seems to have been with the JSCH version between our environments. I included a tloadLibrary for JSCH 0.1.55 - and low and behold it was resolved.
