Hello everyone, my firewall iptables Red Hat 5.7 is show me the follow bellow message when I run a ping to a IP address 172.16.30.2 connect: No buffer space available so... I've just add this network ( 172.16.30.0/30 ) on my firewall in the NIC Interface eth7. the error only accurs when I run a ping from this Interface( eth7 ) or to ip address 172.16.30.2. ( eth7 has ip 172.16.30.1 ) is very strange because when I run a ping to any other ip address all it's work. I have changed the follow values but does't work. # sysctl -w net.ipv4.neigh.default.gc_thresh1=512 # sysctl -w net.ipv4.neigh.default.gc_thresh2=1024 # sysctl -w net.ipv4.neigh.default.gc_thresh3=2048 before I changed this values was 128, 512 and 1024. maybe I have reboot my firewall ? there is other way I solve the problem without reboot ?? I thought it was full arp table but it is with 350 average. thanks -- To unsubscribe from this list: send the line "unsubscribe netfilter" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
