[Samba] SMB Signature verification failed on incoming packet
My setup is Samba/smbclient version 3.0.1 on linux RedHat 9. \\snapper\dfs is a dfs share on snapper, a Win2k3 Active Directory server. My smb.conf contains: [global] realm = ciswinnet.cis.uab.edu workgroup=CISWINNET security = ADS encrypt passwords = yes password server = snapper.cis.uab.edu client use spnego = yes I am trying to run the following command: smbclient \\\\snapper\\dfs <mypassword> -U Administrator -E -W CISWINNET -D home -d0 -Tqca /tmp/junk.tar & This command starts tarring up the contents of \\snapper\dfs\home until a very predictable point, when it fails with the error "SMB Signature verification failed on incoming packet!" I start the command, and it happily runs for about 3 minutes and then... [2004/01/13 17:39:21, 0] libsmb/clientgen.c:cli_receive_smb(121) SMB Signature verification failed on incoming packet!

I'm don't think Kerberos is coming into play here since I'm providing my authentication on the command line, but that's just a guess. Any pointers as to what's going wrong here? The end goal is to backup our dfs share via the Amanda backup software, and this command that I am running is exactly the one that Amanda is trying to run, and seeing the errors that I've outlined here.

[Samba] SMB Signature verification failed on incoming packet
Since posting this yesterday, I've been googling a great deal and there's almost nothing out there for this particular error message. Does anyone have even a general idea of what type of error messages these are? I'm completely at a loss of what to check - I've never seen it where smbclient works until it hits a certain file (also, to update the error, it died at a different file a little further along last night).
