Wireshark · Ethereal-dev: [Ethereal-dev] ringbuffer limits...

["Neulinger, Nathan" <nneul@xxxxxxx>]

We had a small discussion about this a while ago, but never applied any
patch...

I have this ugly hack in my local checkout:

but something better should ideally be used... Perhaps something using
sysconf, or just hardwire something seemingly reasonably like 1024. (If
the user tries to exceed it, who cares, it'll error out.)

I'd like to see something applied though, cause right now on the linux
boxes, it arbitrarily limits max_num_files to 10 (FOPEN_MAX is 16 I
think). Either 10 or 16 would both be nuts when I the actual limit is
1024 on my box by default.
