Files and their sizes is a layer 7 thing, and depends entirely on the application protocol used to transfer them (SMB, CIFS, NFS, FTP, HTTP, SSH, etc.). So the short answer is no, you can't select packages based on file sizes, it doesn't make any sense. But you obviously can select IP packages based on their size (match "length"). However, remember that MTU in normal layer 2 networks, typically ethernet, have a value of 1500 bytes, so I think in normal conditions you will not see any packages larger than that (except if you use jumboframes, FR or the like). -- Jose Luis Domingo Lopez Linux Registered User #189436 Debian Linux Sid (Linux 2.6.0-test9-mm1) _______________________________________________ LARTC mailing list / LARTC@xxxxxxxxxxxxxxx http://mailman.ds9a.nl/mailman/listinfo/lartc HOWTO: http://lartc.org/
