Fix "connect: No buffer spaces available"

When i use traceroute, something shell display "connect: No buffer spaces available".
Edit kernel parameters to fix:
echo 200000 > /proc/sys/net/netfilter/nf_conntrack_max (most important)

echo 8000 > /proc/sys/net/core/somaxconn

echo 8000 > /proc/sys/net/core/netdev_max_backlog

echo "10000 65000" > /proc/sys/net/ipv4/ip_local_port_range

echo 1024 > /proc/sys/net/ipv4/neigh/default/gc_thresh1

echo 2048 > /proc/sys/net/ipv4/neigh/default/gc_thresh2

 echo 4096 > /proc/sys/net/ipv4/neigh/default/gc_thresh3
