[resolved] Error With tFTP component

Anonymous — Sat, 16 Nov 2024 12:48:31 GMT

Hi all !
I have an issue with FTP components. I can connect to my FTP with the tFTPConnection, and when I want to do anything with an other component (like tFTPFileList, tPut, ...) I have this issue :
Exception in component tFTPFileList_1
com.jcraft.jsch.JSchException: failed to send channel request
at com.jcraft.jsch.Request.write(Request.java:65)
at com.jcraft.jsch.RequestSftp.request(RequestSftp.java:47)

at gouvernance.testestest_0_1.testestest.runJobInTOS(testestest.java:691)
at gouvernance.testestest_0_1.testestest.main(testestest.java:565)
I run my job on 3 servers :
- 2 are ok and I can connect and put my files on ;
- 1 which generate this issue ;
I didn't find a lot of post with this issue so anyone can help me or give me some informations ?
Thanks a lot !

Hi
The SFTP support is checked, What's the authentication method?
Best regards

Hi Shong !
The authentication method is SFTP with public key.
You can find a job which throw the exception in Upload slots.
Thanks for your help !

Hi
Maybe you don't the private key or it is a invalid key on the problematic server? You use an existing connection on tFTPFileList, right?

We use the same key on the 3 servers, it's the good one because I can access the directory with WinSCP.
Yes I use the existing connection in my tFTPFileList.
Thanks !

Hi !
We just have to restart the Service to get the modifications of ssh we ask, now everything is good !
We can access the directory.
Thanks !
