Issue with python version on zTurn outdated:

Potential solution: https://mattermost.web.cern.ch/atlas-itkstrips/pl/p4o5ku419fbrxmpgc49q7oyiec

"""

We have the Zturn attached to an Alma linux PC where we configured forwarding of the network packages between the lab network and the Zturn. I am not yet very happy with this solution, but it works. I am actually not sure if this prevents the Zturn to be found by scans, but so far we did not receive complaints.

sudo iptables -t nat -A POSTROUTING -o enp0s20f0u1 -j MASQUERADE sudo iptables -A FORWARD -i enp0s20f0u1 -o enp0s20f0u3 -j ACCEPT sudo iptables -A FORWARD -i enp0s20f0u3 -o enp0s20f0u1 -m state --state RELATED,ESTABLISHED -j ACCEPT

enp0s20f0u3 is the interface connected to Zturn, enp0s20f0u1 is the interface connected to the internet on the PC. I tried setting this up properly with the firewall but did not succeed so far. Another problem we noticed is that the system clock of the Zturn needs to be well synchronized to UTC for the ITKDB access from the GUI to work properly. The time is not synchronized automatically and we do this by calling this regularly from the connecting PC: sshpass -p<ROOTPASSWORD> ssh -t root@192.168.1.2 "date --set \"`date +"%Y-%m-%d %H:%M:%S" -u`\"", where 192.168.1.2 is the zturn iP
