i often compile LEDE/openwrt by myself. with lede-trunk from yesterday horst has errors.
error messages are here: https://plan.leipzig.freifunk.net/issues/373

thanks for your great work，i am now using this tool. my question is "when will this tool support the 802.11ac?".because more and more 802.11ac ap in use

The problem

If horst is configured to filter out all but BEACON packets (-f BEACON), also ACTION packets get printed. This is because ACTION frames are not mapped to any packet type and because all non-mapped types are always included.

Adding a packet type filter always adds the generic frame type filter too (https://github.com/br101/horst/blob/master/conf_options.c#L251) and all packets belonging to generic group are always included (https://github.com/br101/horst/blob/master/main.c#L257) in the results.

So in other words, in this case, all packets with pkt_types == PKT_TYPE_MGMT get included in the results because -f BEACON not only adds PKT_TYPE_BEACON to the filter but also PKT_TYPE_MGMT. This rule matches all action frames because they are not mapped to any packet types, they only belong to the generic management frame group.

Expected behavior

If horst is configured to use inclusive packet type filtering it should filter out all except packets matching the given packet types.

In my opinion, the current behavior is wrong: unmapped frames should not get included in the result set, the filter is inclusive by definition so all non-matching packets should be excluded.

Conclusions

This specific problem could be fixed by adding PKT_TYPE_ACTION and mapping all action frames to it, but I think the problem is more generic and it should be fixed by filtering out (in filter_packet()) all packets which do not have any subtype flags set. Opinions?

@br101 Could you bump libuwifi to the version with the fixed radiotap link? Currently git clone git://github.com/br101/horst.git --recursive is broken (and this breaks building horst in OpenWrt). Thanks!

Tried both the master and stable branch, not seeing any QDATA traffic showing in the 'packet statistics' view.

No QDATA showing on Packet Statistics view

QDATA is seen on default view

Please consider adding installation instructions and what config files are used, in the README.md file.

I cloned the repository and did the suggested make from the readme guide. Here is my output -- any idea what I'm doing wrong?

Hello,

I have a general question about the compilation and dependencies of horst.

Can you explain what is the difference between using libnl, libpcap and libuwifi ?
I'm a bit confused regarding the difference of each library ? (advandatage/disadvantage)

I also don't understand the comment in the "README.md"
"To experimentally build using libpcap (note that libpcap on Linux is not necessary and not recommended) use (Broken right now!):"

What is broken with libpcap?

Is there more than one way to capture the Wifi packet in horst ?
What is the recommended library in horst ?
Can I use two capture libraries at the same time with horst ? (ex: make PCAP=1 ... does it compile with PCAP=1 and LIBNL=1 ?)

thanks for your comments.

I cloned master branch on raspberry pi using
git clone --recursive https://github.com/br101/horst
but the build fails with the error:

pi@rpi-inam:~/horst_master $ make

P.S. I am able to enable monitor mode in Raspberry Pi 3 using nexmon. When I install horst from the stable branch, it gets installed, but exits with "Floating point exception error" after running for a while.

Please consider installing the man files using a make install. Also add how to install the files manually.

The horst man file has the wrong name. To install correctly use something like:

# Note wrong name here, referring to wrong manual page of 1 instead of 8.
cp horst.1 horst.8
gzip horst.8
sudo cp horst.8.gz /usr/share/man/man8/horst.8.gz
gzip horst.conf.5
sudo cp horst.conf.5 /usr/share/man/man5/horst.conf.5.gz

For whats is the rio.conf file, and how to use upload_interval and upload_server options?

horst.sh brings Interfaces up before using them. horst should also be able to do so, in order to fully replace horst.sh after #14 has been implemented.

How to start horst to change channels automatic?
I try

horst -x channel_auto=1 -i mon0 -f NULL -f PROBE -f ASSOC without success.

horst throw error, long time ago it works with this
I have no idea what went wrong

sudo iw wlan0 interface add mon0 type monitor; sudo horst -i mon0
horst: Could not set promisc mode for mon0: Name not unique on network

Currently it's not possible to select a channel like 108 becaus the field for manual channel-input is only 2 chars width.

Hi,
I installed Horst on Raspberry Pi 3 B Jessie OS. Running the program is fine except the Signal output is 99 dB for every ESSID. When the Horst is used on my Openwrt OS I receive what I presume to be accurate signal levels.

• The Horst version on Opnewrt is a little out date. Therefore I believe the problem is with the new version*

Ive looked and can not figure out how to display all ssids in the terminal interface. In the attached image there was over 3x the amount shown in history and output logs. If this is not a current feature, an option to scroll down so all are visible in live capture would be awesome.

I try to compile on OSX 10.10, but can't work.

Seems I miss some header file, any suggestion?

Hi,
I am running horst version 5.1-pre built on raspbian (PI Zero). I run horst as a server and connect to it with a custom Java client.

If I run Horst as horst -i wlan0 -N -p 4260 everything is fine. I get the the data over the network as expected and the user interfaces shows the data as well.

However, if I try quiet mode (both horst -i wlan0 -N -p 4260 -q and horst -i wlan0 -q) I get the following errors before exit:

Try to set max channel width HT40
nl80211 message failed: Object busy
ERROR: Failed to set CH 6 (2437 MHz) HT40+ center 2447
nl80211 message failed: Object busy
ERROR: Failed to set CH 6 (2437 MHz) HT40- center 2427
horst: failed to change the initial channel number: No such device

Is this expected?

I have not tried with the stable version or a new build, as I want some feedback before initiating a new build on a raspberry pi.

Thank you

Sometimes i saw to channel usage larger than 100%, is that normal, any links point to how the channel usage is calculated?

And the bps looks smaller than expected, is that due to the 802.11 capturing in poor performance? The usage is around 100%, but the bps is near 1~ 2 mbps.

Hi! I am using & learning horst recently.But I found that the main display window never delete PR after timeout, I enable WIFI on my phone, then disable WIFI when I see it on display window, and wait for 60 sec, my phone mac address is still there.
I dig into the code and found something. It will delete node info using the code:
// node.c node_timeout() if (n->last_seen < (the_time.tv_sec - conf.node_timeout)) { //... }
last_seen is timestamp of the node:
// node.c copy_nodeinfo() n->last_seen = time(NULL);
the_time is current time:
clock_gettime(CLOCK_MONOTONIC, &the_time);
But, the_time.tv_sec is always smaller then n->last_seen, so it will not delete node info.

When I change
clock_gettime(CLOCK_MONOTONIC, &the_time);
to
clock_gettime(CLOCK_REALTIME, &the_time);
everything is OK.

Is there something wrong or just my misunderstanding of horst?
Thanks!

Would it be possible for you to implement OLSR2 support?

I have HORST running on a RPi 2 with a USB RTL8812AU 802.11a/b/g/n/ac connected.

Hi, Im running horst every few minutes, to capture some data over a Router with openwrt.
My router have some stations connected via wifi, and (almost) every time horst is killed, the stations are disconected.

Im using this command to run horst (run horst, save content, kill after 55 seconds):
(horst -i mon0 -t 60 -f NULL -f QDATA -f PROBE -f ASSOC -o /tmp/capture.csv -q ) & sleep 55 ; kill $!;

and in logread I have this:

How I can prevent the horst left promiscuous mode?

When in the main interface of host, i hit 'c' to get to the Channel menu, and i then press 'm' to set a channel manually, it only allows me to enter a 2 digit channel. I cannot type in for example channel 104. However if i set the 'automatically channel change' option i do see it goes to these channel.

Can the code be updated to allow for channels to be manually set to allow for 3 digit channels? Basically can't manually set to channel 100-165

Hi!

Horst currently uses a tagging scheme like version-X.Y. this makes GitHub generate a tarball (and its content) that is weirdly named:

$ tar zft ../version-5.0.tar.gz  | head -1
horst-version-5.0/

If you would use the more conventional vX.Y or simply X.Y as a naming scheme, Github would strip away that v letter an create a more reasonable tarball:

$ tar zft ../build-area/horst-5.0.tar.gz  | head -1
horst-5.0/

This would be useful for the Debian package I am maintaining as it would make it possible to reproducibly rebuild the original tarball from the Git source more easily.

Thanks!

Provoking an error, by starting horst on an interface which is down, results in the following output:

Set 'interface' = 'wlp2s0'
Can't activate pcap: -9
horst: Couldn't open packet socket: Success

This could be done better :)

• Use pcap_perror() or similar to get a meaningful PCAP error message.
• Stop horst after the first error (There shouldn't be any further error messages). Forgot to check a return value?
• The classical "Error: Success" in the last line also indicates an inpropper return value or errno handling.

(Perhaps I find time to fix this by my self, but not in the near feature)

System: Raspberry Pi 2 with latest(as of 1-2-17) Raspian install. Horst compiled and running
from latest source.
Date stamps in output log file are always 1970, even though system clock/time date etc are all correct.

Hi,

I've encountered a segfault which seems to be introduced by commit 8345a13 (I found out this using git bisect).

The command I use is the following: horst -i mon0 -q -o /tmp/stream -f PROBRQ where /tmp/stream is a named pipe. The command starts correctly and after a few seconds it segfaults. Notice that sometimes it doesn't segfault but it's just frozen and output nothing. Debug log doesn't bring much interesting information...

Let me know if you need more informations, I'm also working on it.

If you issue the following command:

git clone git://github.com/br101/horst.git horst --recursive

it will fail to clone the libuwifi submodule and produce the following error:

fatal: reference is not a tree: 013ba18f9f2589d9478009a3b4abebfb09065054
Unable to checkout '013ba18f9f2589d9478009a3b4abebfb09065054' in submodule path 'libuwifi'

It is easy to see why this occurs if you go to https://github.com/br101/horst and click on the link to the libuwifi submodule (https://github.com/br101/libuwifi/tree/013ba18f9f2589d9478009a3b4abebfb09065054)

I was able to manually clone libuwifi using:

git clone git://github.com/br101/libuwifi libuwifi --recursive

However, when I tried to checkout the commit (013ba18f9f2589d9478009a3b4abebfb09065054) with:

git checkout 013ba18f9f2589d9478009a3b4abebfb09065054

it reproduces the error:

fatal: reference is not a tree: 013ba18f9f2589d9478009a3b4abebfb09065054

I think the problem may be that this particular commit of libuwifi has not been pushed to Github. This means the parent module (horst) is referencing a commit that doesn't exist on Github yet.

Hallo all,

I was trying the latest (Unstable) version of horst using libuwifi. I am getting some linking error with libuwifi.so.1

`./horst: error while loading shared libraries: libuwifi.so.1: cannot open shared object file: No such file or directory

Should I need to set the path to the libuwifi build folder(thats the plan) or whether makefile should be modified into such way that, it is copied into default linux location?

I think the libuwifi.so.1 should be copied into /usr/lib64/ ..and should I modify the makefile ??

Thanks

Everything working fine ,
I use alfa network , AWUS036H
but I don’t get any info about IP/Meash and
if I set “Automatially change channel ”
I get ERROR ,

When scanning you can't turn off the red channels switch data, which is not useful data and just
makes the display difficult to read.

The site says that the latest versions from Git can be compiled on Mac, but attempting to do so fails. Can some compile instructions be provided?

Hi, I'm running Horst on a Raspberry Pi/touchscreen and this menu system. The Horst button triggers a script that includes the following code:

iw wlan2 interface add mon0 type monitor horst -i mon0 -f probrq -o "horst.$(date +%F_%R).log"

When Horst runs, the console window appears with no activity. If I use a keyboard to select 'f' and 'p' to only show probe requests, I get activity. Is the above command incorrect? Is there a command that can run Horst only showing/logging probe requests?

Thank you

Hello,
Is there any way you could support adding location information to each record, every x seconds (or something similar)? I'd love to use GPSd to keep location and time records with my data. Thoughts?

I would love to see babel support in horst:

https://tools.ietf.org/html/rfc6126
https://tools.ietf.org/html/rfc7557
https://tools.ietf.org/html/rfc7298

Thanks in advance, and keep up the nice work!

on OpenWrt trunk/r47244 with horst Version 4.2 (build date Oct 27 2015 10:12:38) in
hybrid mode (ap+adhoc) i can see my own packets:

18: wlan0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc prio state UP qlen 1000
    link/ether f8:d1:11:a9:ce:c8 brd ff:ff:ff:ff:ff:ff
    inet 10.10.5.1/8 brd 10.255.255.255 scope global wlan0
       valid_lft forever preferred_lft forever
    inet6 fe80::fad1:11ff:fea9:cec8/64 scope link 
       valid_lft forever preferred_lft forever
19: wlan0-1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc prio state UP qlen 1000
    link/ether fa:d1:11:a9:ce:c8 brd ff:ff:ff:ff:ff:ff
    inet 10.10.5.2/27 brd 10.10.5.31 scope global wlan0-1
       valid_lft forever preferred_lft forever
    inet6 fe80::f8d1:11ff:fea9:cec8/64 scope link 
       valid_lft forever preferred_lft forever

horst shows e.g. beacons from 'f8:d1:11:a9:ce:c8' (=wlan0) when invoked via:

iw phy phy0 interface add MON type monitor
horst -i MON

Please consider also adding a --version or -v switch to the horst binary. (The only package available for Raspberry Pi is way outdated, and version can only be checked by using apt/dpkg info.)

I'm trying to build cd49bed (of July 29) on a Mac OS X 10.11.6 machine. This causes a build error, see below. Let me know if I can try and help debug the problem, or if there is any additional information about the build environment that you need.
