actually you may have been nuked and not known what caused that 'crash'
that
ever so randomly appeared.
Nuking can happen to anyone connected to the web over a SLIP/PPP line.
its not the sending of large amounts of data in an attempt to overload
anything. its more commonly a 'loophole' exploiter. there are certain
devious, yet ingenious methods of packet corruption that can be sent
down your tcp/ip pipeline. remembering that all data sent via the net
is 'packetized', that is your message (email, zipped game...whatever)
is divided into (most commonly) 512 byte snippets, or little data
bundles.
these snippets/packets are then given individual headers. headers are
little guide maps for each packet. they contain routing information for
the packet to arrive at the same place as its brethren. the headers
also contain information needed by the decoding software (eudora,
netscape,
winzip...etc) to reassemble these fragments of the original file/data
into its former glorious self. side note: voice over the net. the
reason its so hard to make games or voice or music sound good over the
net is this packetizing business... the end of a file (song?) can
actually arrive _before_ the beginning, oweing to internet lag.
ever watch the statistics on RealAudio(tm) streaming audio playing
your fav tune? watch the lost packet and out of order stats.
real time and packetizing were never meant to shake hands and be
friends.
onwards. nuking exploits bizarre programming oversights (bugs?) in
the way the original spec. for tcpip headers. imagine sending someone
a file via tcpip, but you maliciously insert into one of the packet's
headers that this particular header is -1 bytes length... (just
an example folks)... well if your machine cant error check for that
weirdness... boom ... random _appearing_ crash... it looks like
netscape just did one of its infamous crashes...
note: this is a very simplistic, sorta technically accurate description.
i fudged a bit to make it easier to absorb this knowledge...
more than enough purely technical, extremely high-brow, white papers
exist in various internet FAQ'
hope this helps
take care --Hawke'
