    @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.

    @jrey those pfb_*.sh files are the executables Thanks for clarifying the executables. I do not think that the hardware and table entry size won't be problem as the current configuration provides sufficient computation and memory for its operations. Pfsense is running in different hardware, e.g., Intel Xenon Platinum 8272CL processor and maximum table entries is set to 10 times than the default. pfSense Table Stats ------------------- table-entries hard limit 4000000 Table Usage Count 465931

    @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.

    Anyone else happen to notice that when configuring BFD, if you create a peer and select a profile - after save, re-edit the peer and the Profile is not represented. It appears as "None". You have to check the raw config to determine if the profile was actually assigned to the peer. This is on 2.8.1 (all packages up to date as of the date/time of this post). UPDATE: if re-edit and save (without re-configuring the profile none to what you want) - the save will strip the profile from the peer.

    Hi All, I use HAProxy to redirect to a range of https internal resources, this works really well at the moment through the WAN where I have source limits set up, and I can connect to the internal resources from limited external IP Addresses. Given I have tailscale I would like to basically be able to put custom dns entries in to point these hostnames to my pfsense tailscale IP4 address (100.89.148.118) but I am not having any luck getting this working. At the moment, I am just trying to connect to HAProxy using https://100.89.148.118 but it is getting blocked by the firewall. Sep 11 11:55:58 tailscale0 Default deny rule IPv4 (1000000103) 100.89.148.10:53148 100.89.148.118:443 TCP:S I have tried with and without NAT redirecting internally to 127.0.0.1, and I also have rules set up to allow any traffic to and from my tailnets (defined in an alias) but I still keep getting these connections from my other tailscale machines being blocked on the pfsense machine. Can someone give me some pointers on what I am missing because I can see the requests are coming through to the pfsense machine, and in theory the rules should allow it through but I cant see why they don't. I do have tailscale ACL in place, but clearly that is not an issue as the requests are making it through to the firewall. 0/0 B IPv4+6 TCP/UDP TailNets * TailNets * * none Allow across Tailnets 0/0 B IPv4+6 TCP/UDP * * * 443 (HTTPS) * none Allow Tailscale IP4 I also tried adding a EasyRule but because the tailscale0 interface doesn't exist in pfsense it throws an error and won't let me add that rule. Appreciate any help or tips, Cheers.

    I can't reproduce that in a VM. It installs fine and does not complain. Output from ldd shows that the expected libraries are all present. Something else you have installed must be conflicting. Seriously consider moving to 2.1, otherwise you're in for a bunch of manual shell package cleanup if you hope to fix that. The package itself appears to be fine.

    @gogol: The default in the GUI is to automatically add all locally-attached networks to HOME_NET.  You can defeat this and configure your own HOME_NET, but the process is counterintuitive. If I remember well as an alternative you can define your own HOME_NET also in the "Advanced configuration pass-through" section of the interface settings. The default HOME_NET will be overruled. True, this method will also work. Bill

    @phil.davis: e.g. if your postgreSQL password was "0.0" you would have had a problem getting that through to the conf file! If that was your PostgreSQL password you have bigger problems than getting the value into the .conf file  ;) Thanks for fixing that, it's always annoying to find things in PHP that are quirky with 0. Like $t = "0"; empty($t) being true.

    If it is 30MB then maybe it runs out of space in /var (a memory disk on nanoBSD). These days you can change the size of /var (and /tmp) from the GUI (with reboots…), so you could increase /var just for the install, then put it back after. Alix 256MB are reasonably short on memory, so leaving /var bigger than the default might mean you run out of memory for real processes.

    @abbey: I am having trouble accessing certain sites, specifically ones containing proxy or proxies phrases. I have already added this sites to exception list, deselected proxy from weighted terms and even turned off Weighted phrase mode But i still keep getting access denied Weight phrase: proxies In checking logs i see dansguardian: Error connecting via IPC socket to log: No such file or directory Not sure on your IPC error. However, if you've properly entered the exceptions,  you definitely should be able to get to the sites. What shows in your access.log? You should see an exception logged for every site you've entered into the exception list.

    @Sander88: Thanks! It works now. I have added "classtype:bad-unknown; rev:1;" and the alert shows up now.  :) Quite some time back the Snort VRT folks must have changed the Snort binary such that now it requires a classtype: in a rule or it will segfault and crash when the rule fires.  I think in times past the classtype parameter was optional, but apparently not anymore.  Unfortunately very few if any of the Snort custom rules examples show the inclusion of the classtype parameter  :(

    Snort SID 120:3 with antivirus updates

    Snort keeps a previous log of alerts generated by a host, but doesn't actually act based on them. Let's take an example: host 1.1.1.1 was banned because of rule "I don't like this host because." That was considered a false positive and added to the suppression list (or rule disabled is actually the proper procedure). Snort restarted, host removed from blocked tab. A couple days later, the same host, host 1.1.1.1 gets banned because of rule "I don't like all same numbers in IP." Now the blocked tab will say: 1.1.1.1 "I don't like this host because." and a date/time stamp.             "I don't like all same numbers in IP." and a date/time stamp. The host appears to be blocked because of 2 reasons, but snort's most recent ban is based on the most recent alert generated ("I don't like all same numbers in IP."). The older data (I don't like this host because.") is just there to remind us that a host is really really bad. If a host gets banned again after adding some rule to the suppression list/disabling the rule, then snort's interface was not restarted. Or something else triggered on that host. If neither of those happens, then it's not the expected behaviour. Cisco? Is that a microwave oven maker? Can't remember…...oh, THAT cisco. Yeap, snort is pretty much doomed. After they add the remote update feature. Which is needed for the remote backdoor. For remote support of course. Disclaimer: cisco mentioned in the paragraph above is entirely fictional. Any similarities to an actual company are purely coincidental. cough

    Openvpn ip address conflict ?

    You are correct - the OpenVPN link will not route from work to-from home if both work and home have the same subnet (like 192.168.1.0/24). Packets will never get sent across the link, because the source device will think the (remote) target device is in its local LAN, because the target device has an IP address in the local subnet. Time to choose the easiest network to change, and change it. Or even better, during the holiday season, change both. No-one will notice, they will all be on leave  ;)

    739 MB of RAM is a challenge for Snort with a full rule set.  Snort is a memory hog.  Depending on the number of rules active, RAM usage can quickly grow beyond 2 GB.  If your box begins swapping RAM out to the swap file, then performance will slow to a crawl.  Currently the Dashboard does not indicate any swap usage, so that may not be the problem. You can test Snort as the cause of your slowness issue by simply turning Snort off on the interfaces it is running on.  Just click the green arrow icon on the Snort Interfaces tab and wait for it to turn into a red X.  Snort is then stopped and is not consuming any resources nor doing anything to network traffic.  If things are still slow and you have web browsing issues, then Snort is not at fault and you know to look elsewhere. Now if Snort was blocking a number of web sites, that can also give the appearance of being slow.  What happens is most web sites use advertising, and that advertising is served up by external sources (meaning not from the same web server as the content you went to see is served from).  Sometimes those external sources are either known suspicious sites with poor reputations that are on a Snort block list, or the external site may use some non-standard HTTP encoding that the Snort HTTP_INSPECT preprocessor does not like.  Either way the incoming ad stream is blocked.  Some web pages will pause or simply not load when any of their embedded ads don't completely load.  You may be seeing some of that behavior as well.  Properly configuring a Suppress List will help in this area.

    Solved my own problem (sort of).  When I set up pfSense, I created a new administrator account and made it part of the administrator group and disabled the default admin account.  Apparently, the group privileges for the administrator group are not applying to the new admin account.  If I use the default admin account, everything works.  Strange.

    Proxy Exceptions with Dansguardian

    the default status is off and it never comes on and it makes dansguardian unusable since it cant scan content. GUI notifies that freshclam is running but i know its not. By default freshcalm does not have any permissions to run updates, i had previously activated this and fixed all permission errors, but dansguardian always shows clamav status off I got pretty far but could not find clamd.conf as it didnt exist anywhere. Now i reinstalled everything and starting from square and need some directions. Update: On a side-note i got squid (non-transparent mode) working with dansguardian. Just like i want: all traffic is redirected based on my 1 NAT rule, instead of having rules+multiple exceptions. I made a mistake when testing dansguardian proxy which lead me to believe that proxy wasn't working. All i need is Clamav setup and ll be greatful!!! Update2: Got pretty far after finding a thread with same problem. Now i just need to know how to get blacklist working, DG does not download the specified list..
