Hi breda
i found this about the snort settings in http://seclists.org/snort/2014/q3/944:
... [show rest of quote]
so he changed the preprocessor_stream5_ctp and increased the mex_queued_* values. (<a href="http://manual-snort-org.s3-website-us-east-1.amazonaws.com/node17.html#SECTION00322000000000000000 for documentation">Snort manual - 2.2.2 Session)
You could play with these settings but I lack the insight how one setting effects another as I am not too familiar with snort fine tuning.
No more: Shield Pro v1, Chaos Calmer, FW 1.51 SP1

Ok, let's triple it to 3 megs for the queue:
prune_log_max 2097152 max_queued_bytes 3137628 I would also disable unused preprocessors. Hans wrote a script to run which makes it really easy: http://itus.accessinnov.com/Bridge-mode-bugfix-and-performance-improvement-tp561p593.html

Hi, user8446 I'm Sorry it took so long for me to get back to you I updated the size
but only getting DOWNLOAD 48.98Mb/s also on would also disable unused preprocessors. Hans wrote a script to run which makes it really easy I see few files can you tell me the one should use and would I WinSCP them and run them via SSH? prune_log_max 2097152 max_queued_bytes 3137628 Sat Aug 20 12:17:25 2016 daemon.notice snort[12543]: S5: Session exceeded configured max bytes to queue 3137628 using 3138244 bytes (server queue). 66.234.209.81 62630 --> 208.69.40.37 8080 (0) : LWstate 0xf LWFlags 0x6007 |

just copy the file to the temp folder /tmp on the shield with the WinSCP program and then run it via SSH? The script run very fast and you should see the words "moved files" job done snort_preproc_move.sh roadrunnere42 |

type the following
cd /tmp (then press enter) this will take you to the tmp folder, as the shield is based on linux you have to tell the shield that the script in actually in the folder you are in, this is done by put ./ in front for the script name so i normally do sh ./(name of script) roadrunnere42 |
