Re: 2GB limit?

[Shane Williams <shanew () shanew net>]

Actually, this isn't a filesystem limit if you're using ext2 or ext3
on RH 7.2

It might be in snort, but from my expereince with tcpdump, I would
suspect the libpcap package.

I compiled my own libpcap because I was running into the same 2G limit
with tcpdump.  The trick is to add "-D_FILE_OFFSET_BITS=64
-D_LARGEFILE_SOURCE" to the "DEFS =" line in your makefile.  After
replacing the RH supplied libpcap with my version, tcpdump will go
much higher (I can't say for sure, but I've got files as large as 12G
now).

I suspect if you do a search for that string you'll more about this
issue, and a better explanation.
