This just swaps the order that frags are sent out in -f frag scans. This was alluded to by the comment in the send_small_fragz source: /* Lets save this and send it AFTER we send the second one, just to be cute ;) */ As I recall earlier versions of the linux kernel didn't let you do this. Turns out that 2.0.36 and 2.2.5 do in fact let you do this. Patch is pretty much just proof-of-concept. It should probably be implimented with a commandline flag that lets you select if you want reverse frags or not. Also, a time delay in between sending out the two frags might be a good thing. -- Lamont Granquist lamontg () genome washington edu Dept. of Molecular Biotechnology (206)616-5735 fax: (206)685-7344 Box 352145 / University of Washington / Seattle, WA 98195 PGP pubkey: finger lamontg () raven genome washington edu | pgp -fka
