Is it worth building a host attribute table when you only have the
operating system? Basically, is it worth the hassle? Let’s say I only have
the OS for about 100 machines on 3 class B subnets. Most of them are Windows
XP, 2k8 or win7 boxes. There are about 20-30 that are SunOS, linux, or DRAC.




If all you are using the HAT for is to define OS, then it’s probably easier
to setup a new stream5, and frag3 policy and define the IPs there.



My stream5 is setup like this.



preprocessor stream5_global: max_tcp 1048576, memcap 1073741824, track_tcp
yes, track_udp no

preprocessor stream5_tcp: policy windows, use_static_footprint_sizes,
dont_store_large_packets, ports client 21 22 23 25 42 53 79 80 109 110 111
113 119 135 136 137 139 143 110 111 161 445 513 514 691 1433 1521 2100 2301
3128 3306 6665 6666 6667 6668 6669 7000 8000 8080 8180 8888 32770 32771
32772 32773 32774 32775 32776 32777 32778 32779, ports both 443 465 563 636
989 992 993 994 995 7801 7702 7900 7901 7902 7903 7904 7905 7906 6907 7908
7909 7910 7911 7912 7913 7914 7915 7916 7917 7918 7919 7920



So with that said, it seems like it’d be pointless to set it up for
anything that’s a Windows machine, right?



Depends on if you’re going to use the HAT to also define ports, services,
applications… if you are running services on non-standard ports, I say by
all means, add in the Windows boxes so that you get coverage via the
metadata service tags in rules, otherwise you’re going to be missing a bit
of data. (bit is relative here, in my environment, I would miss a lot).


The HAT can also be reloaded without restart.



Thanks,
