Hello I have open a bug quite a while ago https://bugzilla.samba.org/show_bug.cgi?id=9477 and don't have any news. I am using sec=krb5i, but have the same problem with ntlmv2... The problem is the same with a centos 6 computer. Perhaps the problem is in the Windows Server ... Do I have to change AllowLegacySrvCall as described in http://support.microsoft.com/kb/957441 ? Perhaps I have to put a more recent driver in my server: It is a Dell T610 server with a NetExtreme II gigabitE (version 5.2.14 17/12/2009) ? Please help , as the problems continue ... Thanks Serge Conrad Hello ... in the messages, you could see an SMB unexpected signature (21 Jan 16:13:16) In the dump file , the trame no 470 is at the same time (16:13:16) The environnement is the same as described in https://bugzilla.samba.org/show_bug.cgi?id=9477 Regards, Serge > Message du 25/01/13 16:15 > De : "Steve French" > A : "sergio. conrad" > Copie à : > Objet : Re: CIFS VFS: Unexpected SMB signature ...NULL inode in lookup > > You could send the trace to me directly > On Jan 25, 2013 8:42 AM, "sergio.conrad" wrote: > > > Hello > > I do have a network trace for > > https://bugzilla.samba.org/show_bug.cgi?id=9477 > > But there is the public adress ip of the server in the trace.
