Hello Dan,

When in your case, the SD opens a socket, it looks for the hostname, and for some reason it did not find it. Are you 100% sure that the DNS resolver is working on your SD machine?  What do you have set for SDCallsClient?  Perhaps for some particular SDCallsClient, the SD does not have everything it needs for filling in the error message. 

Best regards,
Kern

NOTE: this message is not about resolving the permissions error.  It is about [what appears to be] a DNS issue.

Please help me understand which hostname is not being resolved in these messages.  My checks with dig to verify DNS have found no errors.

I have checked:

Client:                 crey-fd
Read Storage:           "bacula-sd-01-file" 
Write Storage:          "tape01" (From Job resource)

I've checked the bacula configuration files, looked for the Address, and run 'dig +short' on the hostname

Then, with the IP address from the previous dig, I do 'dig +short -x'.  I get the original hostname.

Ideas please?
