[Snort-users] I need some serious help

thats the problem, snort is setup for tcpdump, i cannot replay the dump
files, it gives an error, reading the files in an editor reveals there are a
number of codered scans, and apparently something in the code prevents the
playback, using the command line
snort -dr snort.log -c c:\extract\snort.conf -l c:\extract\log
snort is restarted daily, creating 0606 at ...6048... 0607 at ...6048..., and
so on, i copy the logs to/from a remote system and play them back to get the
alerts and log structure for parsing and investigation, these particular
files from just this system, when i go to rename them to snort.log for the
extraction process, it says in use, cannot be renamed, and the file then
self-deletes. weird i say.

You need to turn on binary logging.  You can do that in two ways:

  1)  Adding "-b" to the command line
  2)  Adding "output log_tcpdump: snort.log" into your snort.conf file.

Now you've got the packets, what do you want to do with them?  Read/replay
them at your leisure?

	snort -vader <logfile>

Will dump them out to your screen.  Pipe to pager program of your choice and
read from there.

Hope that helps!
