    I am new to using Snort in a Netgate router with pfSense. In the Snort settings under alerts I am seeing notice like this: 2025-09-08 16:34:17 1 UDP Attempted User Privilege Gain 37.60.141.158 47167 195.252.###.### 9034 1:58853 SERVER-OTHER RealTek UDPServer command injection attempt Does this mean that someone from 37.60.141.158 tried to login to my router or is trying to log in to my router? Does SNORT block this attempt? or How do I block this attempt? There is nothing showing up in my BLOCKED list. Will snort ONLY block these IP's if I have "Block Offenders" checked? If yes, should I use legacy mode or inline mode? My understanding is that if I use legacy mode all rules will be enabled and any alerts will be automatically blocked right? If I use inline mode, then NO rules will be automatically blocked and I would have to enable the action for that rule for it to be blocked, right? If I use inline mode, how do I enable a rule? Right now I just have a yellow triangle under the action for this rule. How do I know which rules is snort using? Under WAN Categories, If I choose balance, NONE of the rulesets (Categories) shown at the bottom are checked? Here is another alert that I m wondering about: 2025-09-08 08:38:21 3 Generic Protocol Command Decode 97.78.###.### 24.172.###.### 123:8 (spp_frag3) Fragmentation overlap The source IP 97.78.###.### is my main office IP address and the Destination IP 24.172.###.### is my branch office. I'm not sure what this is and I definitely don't want this data being blocked by SNORT, so would this be a good reason to NOT use legacy mode in the Blocked Offenders section?

    @Antibiotic No it’s not possible with NtopNG as it is not a Netflow collector. You need nProbe for that which will “translate” recieved netflows into flows that NtopNG understands and can visualize (with very very little detail might I add as Netflows has no additonal information apart from sender/reciever and volume). The NtopNG package and the product in general is more geared towards visualising and recording traffic details from actual packet captures. This contains MUCH more metadata about the sessions than netflows (DNS names, protocol information and myriads of other things). But pffSense Plus has a builtin Netflow exporter if you have an external netflow collector on hand.

    @BiloxiGeek said in DNSBL and IPv6: Does it just follow the IPv4 address that is listed above that? In my case it would end up being ::10.0.0.86 Yes. In this specific context that's the notation being used. (Full IPv6 web server address, for reference then, would be: http://[0000:0000:0000:0000:0010:0000:0000:0086]) Nota bene: I use 0.0.0.0 which renders the DNSBL webserver useless and inaccessible, but otherwise returns 0.0.0.0 or ::/NOERROR answers to all blocked lookups.

    @jhg said in NUT fails to start after 2.7.2 -> 2.8.0 upgrade: Interesting. I would have thought the initial reboot, which occurred as part of the upgrade, would have done the trick, but it took a second reboot, just now, to get things working. Glad you have it sorted. There was no difference in the output of usbconfig show_ifdrv at any point -- before or after unplugging/replugging the USB cable, nor after rebooting. ... Question: What would tell me whether or not a driver was loaded? If there were an attached driver, it should have shown up with the show_ifdrv command. If you use the command and look at the other usb devices, I think they will show attached drivers. I don't expect to see a driver attached to the ups, because there is a quirk that tells the OS to ignore that device (and not attach a driver). Look for idVendor and idProduct in the above output. The Vendor ID for your device is 0764, which corresponds to Cyber Power Systems, and the Product ID for your device is 0601, which is registered as "PR1500LCDRT2U UPS" (don't sweat an exact match for the name). You can see the quirk with the following command: [25.07-RC][root@fw]/root: usbconfig dump_device_quirks | grep 0764 VID=0x0764 PID=0x0005 REVLO=0x0000 REVHI=0xffff QUIRK=UQ_HID_IGNORE VID=0x0764 PID=0x0501 REVLO=0x0000 REVHI=0xffff QUIRK=UQ_HID_IGNORE VID=0x0764 PID=0x0601 REVLO=0x0000 REVHI=0xffff QUIRK=UQ_HID_IGNORE [25.07-RC][root@fw]/root: Your device is third on the list. The HID_IGNORE quirk says to ignore the device and not attach a driver. @jhg said in NUT fails to start after 2.7.2 -> 2.8.0 upgrade: You might consider adding this resolution to the release notes for 2.8. LOL... sorry, I don't have input to the release notes (I don't work here). While I wrote and maintain various packages, including NUT, I'm still just a volunteer. Most packages are actually written by volunteers.

    Thanks guys for your replies. Just to clarify so pfSense allow users to have two interfaces (LAN and WAN ) on SNORT so users are able to choose whether to set SNORT on LAN/ WAN or both depending on where does pfSense is install (public facing servers or not?) and how do the user want to protect their network ?

    Apparently these packages are all screwed up in 2.2. Getting nothing but TCP_Miss/503 and other similar errors with Squid3 all by itself. I'm not even touching dansguardian now and these are the issues that I am getting. So frustrated with this.

    There have been a few reports of this - something happens to php-fpm. It does not happen [often/for many people] and so the root cause and the fix have not been found. If you have any interesting observations about our system, and anything interesting in logs then please post. Sorry to not be of any direct help!

    @power_matz: Thank you for your answer. Here are the facts: Filesystem          Size    Used  Avail Capacity  Mounted on /dev/ufs/pfsense0    1.8G    295M    1.4G    17%    / devfs                1.0K    1.0K      0B  100%    /dev /dev/ufs/cf          49M    1.4M    44M    3%    /cf /dev/md0              38M    680K    35M    2%    /tmp /dev/md1              58M    18M    35M    34%    /var devfs                1.0K    1.0K      0B  100%    /var/dhcpd/dev It should be sufficient, or? No, your /tmp and /var partitions are probably too small depending on the exact number of rules you have.  You want at least 100 MB available and you are showing only 35 MB available. Bill

    [bump] last call for help before I just nuke and pave. Update 28/02 for anyone who encounters a similar problem: Backed up configuration, nuked, paved, restored config. Issue was resolved. My guess is that an update failed in the middle of writing files or something similar and borked some download functions.

    @enivre1717: Because my boss want to know what is the pros and cons of using barnyard in SNORT. I can't find any from google. https://github.com/firnsy/barnyard2 Read the description part. Basically you use barnyard2 to send alert and other data to a SQL database and then use something like Snorby (https://snorby.org/) to view that data. This isn't really something that you can make a pros/cons list off. It's something you need or don't.

    The "old" squidGuard package for 2.x didn't work. Not even for 2.x. However the -squid3 variant works for both 3.x and 2.x now, so I combined them back into one package. The current "squidGuard" is the same as the old "squidGuard-squid3" – only difference is the name. :-)

    @jflsakfja: Don't care about real time lookups, but a per minute lookup would be nice to stick into a variable. Just saying… ;) Can't pfsense's existing setup be used for that? Since the majority will be doing their realtime lookups through unbound, it should be pretty fast, even when used in realtime, with regards to keeping up with traffic. Not talking about a 10Gbps snort (don't even know if it can push up to that)/suricata looking up a billion IPv6 addresses. Talking about sticking an alias to suricata, having it look up a single (or few) hosts to allow for a VPN for example to be tightened down. Used with an allow only VPN access from this host suricata rule, for example. Yes that can be done with normal pfsense rules, but it's an example.  :D Sorry for taking over the thread Mr. Jingles, but I fixed it near the end  ;D I have considered perhaps leveraging the filterdns daemon and its alias tables within pfSense to allow some small level of FQDN support for pass list entries.  It would take some significant mods to the way the old Spoink output plugin for Snort has been engineered.  Today it reads a simple text file of IP addresses and stores them in a linked list in memory once at startup.  Whenever a "block or no block" decision is required, that in-memory IP list is scanned to see if the source IP, destination IP or both are in the list.  If true, the block is not inserted into the <snort2c>alias table in pf.  Of course the "which IP to block" setting is also part of the logic.
