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 >

Hi, I am getting below error on mailgw. it has 2 ethernets. eth0 is connected to internet, while eth1 is connected to LAN where there are about 300 PCs.

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 is set.

Hey guys, I have several Linux routers in place at high-usage locations (student apartment complexes). I''m having trouble with some of the routers which use 6Mbit DSL lines as their Internet feed. The routers use PPPoE and perform NAT. During peak usage periods, the routers are dropping alot of packets. I''m lead to believe this is because there are too many active

I''ve got a linux router pushing 600-1000 pppoe connections through it. I''m getting a screen error "Neighbor Table Overflow" after this box has been up for between 1 week and 1 month. When this is happening, routing slows to a crawl if at all. Then dies. I''ve added: # Added to stop "neighbor table overflow" messages in the kernel

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

Hey guys, I am planning to buy some components for a Linux router that will handle the Internet access of 200 computers (includes tc shaping) and some inter sub-network routing (at least 100MBps per eth - and there are 3 eth cards). I was thinking of a: Pentium 4 - 3GHz 256 or 512MB RAM Network Cards. Now - I wonder what is more important: the processor speed or the amount of RAM. And can you

Hi, I regularly have errors (kernel: dst cache overflow) and crash of a firewall under Linux 2.6.17 and the route patch from Julian Anastasov. With rtstat I see that the route cache size increases regularly without never decreasing. I have this parameters: fw:/proc/sys/net/ipv4/route# grep . * error_burst:1250 error_cost:250 gc_elasticity:15 gc_interval:60 gc_min_interval:0

what is the limit on the arp cache entires ?! Does someone have very big LANs with linux-routers ? How big ? (i mean flat L2 network, not segmented) I want to know how much can my net can scale ? thanx _______________________________________________ LARTC mailing list / LARTC@mailman.ds9a.nl http://mailman.ds9a.nl/mailman/listinfo/lartc HOWTO: http://lartc.org/

May I ask whether it would be possible to create a wine list for fundamental problems of wine, leaving out all problems related to war, game, and so on, software? If I were interested in I would have taken Windows, while such e-mails are really flooding. There are people interested to run a few scientific applications that are not yet available on linux or other unix OS (while expecting that

Hi all, I need to provide shell hosting for about 40 users, and few days ago I found the wondershaper script, so Im trying to know if this script could help me to improve interactive ssh/telnet connections. Wondershaper could help me or its only efective on OUTGOINGS requests? Ok, any comment and feedback will be welcome. Sorry for my bad english and THANKS in advance.

Sir, Kindly excuse me. I am a newbie to LARTC.. I am a small ISP in rural India distributing 1 MB link to 200 people. I have been using rshaper by Alessandro Rubini for shaping. http://freshmeat.net/projects/rshaper/ My kernel is Linux version 2.4.22-1.2115.nptl( Fedora Core 1) Rshaper is very good in controlling incoming bandwidth (from LAN) I use Squid also on this Linux Box.. Right

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

hi all, i am getting a lot of neighbour table overflow in my syslog file... we use slavkware8.1 with kernel2.4.19 squid2.5s1 iptables1.2.7a & iproite-ss020116.. there are two providers & this box has 5 ethernet and i havent seen it handle going less that 2.5mb traffic even at off peak hours !.. the kernel was _NOT_ configured with arp daemon support..

Guys Considering the festive season is upon us, thanks to everyone contributing to the list and helping all the readers with your great input! I don''t want to mention names, I''ll most certainly leave someone out. With this mail I''d like to test some theory on bandwidth management, with my own successes and failures during the past year. Sharing a link between 200

Hi, I'm new to this list but not to Samba. I've recently been having problems with Samba that I have not encountered (ever). I cannot determine what the cause is but an hour or so into my dialup connection, my machine starts flooding the first dns server in /etc/resolv.conf with dns requests. I know it's samba responsible for the flooding because as soon as I kill both smbd and nmbd

The problem is that I have only 2 ethernet adapters in my linux router, one of this adapter pluged to the LAN and the other is pluged to a HUB who have 2 routers DSL. Each DSL routers have an static ip and the solution that I found was creating an eth0 and eth0:1 but with this option I have any way to use the eth0:1 adapte... Any one knows a solution for this ? Regards.

Guys Reading through my lartc mail, and thinking on how to tackle my next shaping solution, gave me an idea. I''d like to propose this idea for scrutiny and if it sounds viable I''ll definitely need to start developing in due time. For me in my day to day work with developing network application specifically geared for middle-tier ISP''s, and reading on other peoples
