[Samba] [EXTERNAL] Could not access a share as a guest

[Neelakantan Kannappa (nkannapp)]

Appreciate your help.

Yes that is true. Those files are created by some other Application(which are shared through samba).

Ran wireshark, captured the packets and filtered for SMB2. Attached SMB2 filtered packets in a plain text format.

I don't know what is happening from the packet tracing.

SMB did create request, create response and immediately close request & close response.  Session logged off.

Even I tried "ea support = no" that also did not help.

Tried other alternative with below smb conf.

#   acl_xattr:ignore hashes = yes
#   acl_xattr:ignore system acls = yes
#   acl_xattr:default acl style = everyone

Things work properly when windows client & samba server(linux) nodes are joined to a domain.

Thanks,
Neelakantan K.

That is not necessarily an error. The file may not have had the DOS attributes stored on it yet, if this is the first time it's being accessed by Samba (on read for example).
