[gentoo-user] lots of wierd traffic with smb mounted share

[Iain Buchanan]

I have autofs mounting a windows share on my network, 's'.  This is the
line from the automount file:
s -fstype=smbfs,defaults,gid=mounter,dmask=770,fmask=660,credentials=<file>  ://server1/public

However, I noticed recently there was quite a bit of traffic (5k/s)
whenever this share was mounted, when I'm not copying anything.  When I
look at ethereal, I see this sort of pattern repeated continuously:

No.     Time        Source                Destination           Protocol Info

     74 3.008458    172.16.0.1            172.16.0.52           SMB      Trans2 Response, QUERY_PATH_INFO[Unreassembled Packet]
     75 3.008525    172.16.0.52           172.16.0.1            SMB      Trans2 Request, QUERY_PATH_INFO, Query File All Info, Path: \
     76 3.008853    172.16.0.1            172.16.0.52           SMB      Trans2 Response, QUERY_PATH_INFO[Unreassembled Packet]

I have no idea what a "Query Information Disk Request" is, so any info
would be appreciated!  I tried with and without iptables activated, and
the result is the same.

Thanks.
