Snort



  • Snort fails to start with pfsense now after the last up date 1.26.



  • works here



  • ~~Same here,
    Does not start for me after 1.26 update (from 1.25)

    Log Error:
    snort[11812]: FATAL ERROR: parser.c(5161) Could not stat dynamic module path "/usr/local/lib/snort/dynamicrules/": No such file or directory.

    OP: just a friendly suggestion… i would change your title of the Thread to something like
    "Snort: won't start after 1.26 upgrade"
    Also, what do you have in your logs?

    You might want to list your PF version also to help JamesDean and others.

    My Box:
    PF 1.2.3 Full~~

    CDX304: Update your rule and try to start Snort.

    I forgot to do this after the install…After Rule update...all is good.
    :)



  • It does not matter i did the update twice and still not start with reboot .



  • @cdx304:

    It does not matter i did the update twice and still not start with reboot .

    Did you try to re-save you interface settings. That will rebuild your missing files.

    James



  • Yes sir i did re-save the settings .



  • What is in the system log?
    Any Errors?

  • If i restart pfsense …..I have to manually start snort it will not otherwise .



  • This may or may not be in the same related problem-field but I've found that with mine I have to disable any 'Emerging' categories and then save.  I'll get the same or similar error (no pattern really) of conf not found.

    Then enable the emerging threats one at a time until I find one that causes an error so I just leave that one out.

    It has happened a few times now, but by the next rule update that particular category (changes which one each time) is fixed - though another might have a problem.

    Might try that if you have the problem again and other solutions don't work.  IF you use those categories :)



  • I tried that and it does not work .

    Version 1.25 worked fine but the updates  would not work .



  • Have you even seen if the file or directory truely exists? If the directory exits but not the file have you tried " touch /usr/local/etc/snort/snort_9698_fxp0/snort.conf" in the shell?

    g4m3c4ck has a good idea.

    I have a few hours this morning to work on this issue.
    I'm going to add code to create missing files when a save is executed.
