Hi there,

Newby question, please. I have installed a headless node on an Ubuntu 16.04
At node start I have 4 errors strings:
"sendto: Operation not permitted
sendto: Operation not permitted
sendto: Operation not permitted
sendto: Operation not permitted"


I have opened UDP port for peering in the firewall with no result:
#nano In/Out
/sbin/iptables -t filter -A OUTPUT -p udp --dport 7075 -j ACCEPT
/sbin/iptables -t filter -A INPUT -p udp --dport 7075 -j ACCEPT

What am I missing? Thank you.

Are you directing packets to a table called filter? Any other rules you have got in place?

Maybe try this instead:

Code:
/sbin/iptables -I INPUT -p udp --dport 7075 -j ACCEPT
/sbin/iptables -I OUTPUT -p udp --dport 7075 -j ACCEPT
