Just started getting this. I tried the following by adding it to my etc/sysctl.conf: net.ipv4.neigh.default.gc_thresh1 = 4096 net.ipv4.neigh.default.gc_thresh2 = 8192 net.ipv4.neigh.default.gc_thresh3 = 8192 net.ipv4.neigh.default.base_reachable_time = 86400 net.ipv4.neigh.default.gc_stale_time = 86400 That pretty much locked things up. Then I tried another googled solution: echo 256 > /p...

OK please try the following patch [PATCH] neighbour: fix a race in neigh_destroy() There is a race in neighbour code, because neigh_destroy() uses skb_queue_purge(&neigh->arp_queue) without holding neighbour lock, while other parts of the code assume neighbour rwlock is what protects arp_queue Convert all skb_queue_purge() calls to the...

Dear Dr. Bivand and R-users, I have a 5 by 5 grid, say, location[1:5,1:5], and I want to know the indices of 8 neighbours of each cell. For example, for location[2,2], its neighbour coordinates are [1,1:3], [2,1], [2,3] and [3,1:3]. Sometimes I also need to remove edge effects (torus = TRUE). I have tried "cell2nb" function in your spdep package. Here's my example: > neigh <- cell2nb(5,5,t...

Hello, I know that there are devices which are not working with arp. For example, the loopback device. I was wondering whether it is possible to create neighbours in a NUD_NOARP state; so that "ip neigh show" will show such neighbours where their state is NUD_ARP. I made some tests with the loopback device , but could not find such a way to cause it to appear as NUD_NOARP. Also if I ping a (nonexisting) multicast address (like 224.0.0.0) I don...

Hi guys, Sorry if this is a little offtopic, but I was wandering what can one do to prevent/stop arp flooding ? Thanks, Alex -- This message has been scanned for viruses and dangerous content by LG-Network(http://www.lgnet.ro), and is believed to be clean.

Hi, all When use Centos 6.5,kernel version 2.6.431, I have continuous messages of "Neighbour table overflow" in messages. I have modified the gc_thresh1(512) , gc_thresh2 (2048) gc_thresh3 (4096) in /proc/sys/net.. path, But the messages occurs occasionally. some forum saied: They are probably realted to a kernel bug where the thresholds are in fact only half of the value that i...

Hi, I try to set up - A centos 6 firewall - With proxy-arp (I know: arp is not supported in ipv6) with ipv6. Arp does not exist for ipv6. So I have added: sysctl -w net.ipv6.conf.default.proxy_ndp=1 To use the neighbor proxy facility. How to activate ipv6 forwarding? As far as I have found, this changed in RHEL6 from 6.1 (/etc/sysconfig/network) to 6.2 (/etc/sysctl.conf). CentOS 6? So I have used sysctl -w net.ipv6.conf.all.forwarding=1 as in RHEL 6.2 As in ipv4 I would prefer to proxy the...

Hi, I have a P4 @ 3Ghz router running Debian. It shapes traffic ( about 500-600 classes ), about 1000 iptables rules, and it does BGP too, so i get about 1300+ routes in the routing table. The problem is the load is too high on this system. I found a solution to my problem, turning off the route cache, but i dont know how to implement it, I was wondering if anyone found a way to disable the
