[Samba] signing failures during smbclient tar operation: SMB signature check failed
(Samba 3.0.1, RedHat 9, share is a w2k3, security = ADS) Here is a snippet of debug level 3 output of an smbclient tar operation, with error at the end.

[Samba] signing failures during smbclient tar operation: SMB signature check failed
[next time I won't hit send before finishing my thought, sorry] The interesting thing is that: # smbclient \\\\snapper\\dfs <password> -U Administrator -E -W CISWINNET -D home -d3 -Tqca /tmp/test.tar produces.... \home\faculty\bryant\bryantback-brblt\Images\backups\backup20010502.zip of size 15593375 bytes as a tar file backup20010502.zipnread=0 [2004/01/14 15:05:10, 3] client/clitar.c:do_atar(693) nread=65520 [snip] [2004/01/14 15:05:12, 3] client/clitar.c:do_atar(693) nread=11597040 [2004/01/14 15:05:12, 1] libsmb/smb_signing.c:signing_good(205) signing_good: SMB signature check failed on seq 7!

So it's not the particular file that causes it to fail, but perhaps when it hits a certain threshold for total amount of data? Should I be taking this to one of the more technical lists? Thanks, Fran
