Just want to share this very short code snippet that helped me to Convert Linux /proc/net/tcp (currently active tcp connections) from hex to human readable format - IPs with ports, helps with troubleshooting :)

cat /proc/net/tcp | awk '{x=strtonum("0x"substr($3,index($3,":")-2,2)); for (i=5; i>0; i-=2) x = x"."strtonum("0x"substr($3,i,2))}{print x":"strtonum("0x"substr($3,index($3,":")+1,4))}' | uniq
