[Samba] smbclient 4.0.7 resolves host name to IP address for SMB2 but not NT1

[Tompkins, Michael]

This is still a lingering problem  with SMB2. It uses 2 different functions to send the Tree Connect Andx Request for NT1 and Tree Connect Request for SMB2. The both call internal_resolve_name to resolve the hostname, but for NT1 is passes the hostname through and for SMB2 it uses the IP address. This is the issue we're trying to address:

I'm sure other people had this issue and resolved it. Either the client has to be told to send the hostname for SMB2, or something on the server has to be configured differently so it can accept IP addresses for these configurations.

You posted:

Is there a way to turn off resolving the hostname in either the smb.conf file or as a command line option to smbclient using SMB2/3 ?

Using '-I' is a command line option that turns off using the hostname.

If this is not what you require, then please be a bit more specific!
