[alcatel-nsp] Debugging SFTP client on Nokia ISAM 7360 5.5.02

[Philip Olsson]

Hi,

I have been struggling for a while trying to get the SFTP client ( for database backup ) on Nokia ISAM to work with OpenSSH_7.9p1. ( FreeBSD ) on the server side.

After enabling some legacy algorithms in the server I have now gotten to the part where it seems to open the sftp channel but nothing is uploaded. 

If I run this to an older server, it works. 

My daemon logs reveal nothing interesting and if I run in 'sshd -ddd', I see nothing. 

I have looked in the user guide but I'm at a loss on how to debug the ssh/sftp client  on the ISAM itself. Log-id 99 and my efforts so far reveal nothing. 

Do anyone know how to get output from the SFTP/SSH client on the ISAM?

Please see below for some more output.

Best Regards,
Philip


My backup command to start transfer is 
configure software-mngt database backup activate:192.168.1.2:olt/ auto-backup-intvl 1

My user is configured as follows:

config system security ssh 
    sftp-user
      backup
      password encrypted:ab:de:ad:ca:fe:ca:fe

ISAM output:
