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