Hi,

Im trying to make the backup from Cisco Callmanager to FreeNas server, but i have some version wonking, and other dont. I dont understand why?
If i use my pc using freeftpd it works, but if i configure the Disaster Recovery to go to FreeNas its not working?
Does anyone knows this issue?

Best Regards,

This is the usual confusion between SFTP and FTP. SFTP is a variant of SSH, and uses the SSH service on FreeNAS, NOT the FTP service.

Look in /var/log/auth.log to see where the cipher mismatch is happening.

I am not sure how to apply that to the sshd_config in FreeNAS, but here is what I use for SSH servers that will act as backup devices for a Cisco Linux appliance.
Code:
KexAlgorithms +diffie-hellman-group1-sha1
KexAlgorithms +diffie-hellman-group-exchange-sha1

Ciphers +aes128-cbc
Ciphers +3des-cbc

Those values are the ones I use for fairly current versions of CM. Older versions may need this as well in the sshd_config.
Code:
Ciphers +blowfish-cbc

Yes, all these values go in Services -> SSH -> Edit -> Extra options.

Hi,

I have 99% of my cucm bck resolved with your tips. I just put the ciphers that you mentioned in Extra Option in SSH service.

Many thanks, for this.

But now im having another strange issue. I have one cucm with presence, the cucm makes the backup but the presence fails an it gives this message "109-Unable to transfer the tar file over SFTP channel as currently configured SFTP server does not support output stream "

Do you any ideas?

Is it possible one of the VM's is low on space? "show status" from the CLI. If that doesn't show you anything with low space then try "show tech runtime disk". If nothing is there then you will have to look at the trace files to see why it is unhappy.
