Ok, I had a look at both captures. The main difference (as Shirish pointed out earlier) is that the server is requesting share mode security in some cases and user mode in another. It does this early on, during the NEGOTIATE PROTOCOL phase, so the user you're authenticating as and the actual tree you're connecting to probably don't matter here. What does matter is the info that the client is sending in the NEGOTIATE PROTOCOL request. There's some key difference here that's causing the server to behave differently. The main differences I can see are: 1/ The older client (slackware) doesn't set the NT error codes bit in flags2. 2/ The older client sends a smaller list of dialects than the newer one ...and that's really it as far as I can tell. What might be interesting is a test patch that makes the negprot request from the newer client look like the older one. Either way, this is almost certainly a server bug and it's doubtful we can reasonably fix this from the client side. -- Jeff Layton <jlayton@xxxxxxxxx> -- To unsubscribe from this list: send the line "unsubscribe linux-cifs" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
