unable to detect camera on ubuntu

[DigitalRowlet]

HI!
After installing the precompiled packages of tiscamera, I attempted to launch the tcam-capture program, only to find a blank window when selecting a device. By the way, I can use the camera normally on the Windows system of the same device. I tried some commands in the terminal with the following results:

cam-ctrl --version
Versions: 
    Tcam:    1.1.1_master/ee45fcf7_rev_4142
    Aravis:    0.8_version_e977fa4
    Modules:    gst_aravis_arvu3v_v4l2_libusb_tools_doc_tests

tcam-gigetool list
No cameras found.

gst-launch-1.0 tcambin ! videoconvert ! ximagesink
WARNING: erroneous pipeline: no element "tcambin"

gst-inspect-1-0 tcambin
gst-inspect-1-0: command not found

Could you kindly provide assistance regarding this issue? Thank you in advance for your help.

computer used (please complete the following information):

• OS: Ubuntu 20.04.6 LTS
• Architecture/Platform: amd64
• Camera : 33GX264

Hello

Did you configure the camera' and network controller's IP addresses correctly? Please have a look at

and

Thank you for your response, but it seems that it didn't work. I tried the commands from the wiki:

sudo sysctl -w net.ipv4.conf.enp2s0.rpfilters=0
sudo sysctl -w net.ipv4.conf.enp7s1.rpfilters=0
sysctl: cannot stat /proc/sys/net/ipv4/conf/enp2s0/rpfilters: No such file or directory

Then I attempted to modify the '/etc/sysctl.conf' file:

No cameras found.

However, even after these steps, the camera still couldn't be detected. Did I miss something?

Hello

"enp2s0" and "enp7s1" are names of network connections. These are samples, as they are on your computer. Your ifconfig output shows, your networks have different names: "enp0s31f6" and "wlp0s20f3". I would guess, the camera is connected to "enp0s31f6", but this controller uses an IV v6 not v4 address.

Is the camera powered? Do your use

• an external power supply or
• a 1GB PoE Injector or
• a 1GBs ethernet switch ?
  Do the LEDs light on the camera's RJ45 jack, as mentioned in the linked knowledbase?

The camera is indeed connected to "enp0s31f6", and I've already modified its properties as follows:

(base) wk@wk-HP-ZBook-Fury-17-3-inch-G8-Mobile-Workstation-PC:~$ sysctl net.ipv4.conf.enp0s31f6.rp_filter
net.ipv4.conf.enp0s31f6.rp_filter = 0

Regarding the connection setup, the camera is connected directly to the Ethernet port of my laptop. Both LEDs on the camera's RJ45 jack and on the laptop are lit correctly. Furthermore, when I switch the laptop's operating system to Windows, the camera works perfectly fine.

Could you please advise on the specific steps I should take next?

Hello

"enp0s31f6" must support IPv4 protocol. Your ipconfig output says, it has IP v6 only. Thus, please change or add this configuration on your Linux.
