unable to detect camera on ubuntu about tiscamera

[TIS-Stefan]

Hello

Did you configure the camera' and network controller's IP addresses correctly? Please have a look at
https://wiki.theimagingsource.com/index.php/Configure_GigE_Camera_IP_Addresses_in_Linux
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:

(base) wk@wk-HP-ZBook-Fury-17-3-inch-G8-Mobile-Workstation-PC:~$ tcam-gigetool list

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.
