SFTP repository issues - sftp_run_parent Error: unable to handle sftp

[Chess Norris]

Hello,

I have some issues with setting up a sftp repository on ISE 3.1. I use a synology NAS  as sftp server but I have alo tried to use the  solar winds sftp server on a PC with the same result. Using sftp from my windows machine works to both sftp servers. 

This is what I see in ISE CLI after adding the host key and turned on debug transfer 7

% Error: Repository SFTP-REPO could not be accessed. In case Backup was Restored on different setup, Please reconfigure the repository passwords (expected behaviour) 

Any one know what the problem could be? 

Thanks

I was able to solve it by changing the path from "/volume1/ISE_Backups/" to just "/" Not really sure why, but it works now.

[Arne Bier]

Most likely because the home directory that is assigned to that user account is /volume1/ISE_Backups - many ftp/sftp servers will "jail" the user account to their home directory (for security reasons) - and when you connect to the server, the absolute path no longer makes sense to the server - your root is now / , and not /volume/....

on my case it was the other way around, 

repository myrepository
url sftp: //10.10.10.100/home/backups/
user test password hash XXXXXX

#

ISENODE/admin#show repository myrepository
