similar to: How To for IPV6

To route a subnet in ipv6 there are two possibilities: - add route commands for the subnet in each computer - or use neighbor proxy in the router server I prefer neighbor proxy. So I have to activate neighbor proxy in the router: sysctl -w net.ipv6.conf.all.proxy_ndp=1 and I have to add entries for each client in the subnet like ip -6 neigh add proxy

Hi! For my network setup I need the following commands: sysctl -w net.ipv6.conf.all.proxy_ndp=1 ip -6 neigh add proxy 1234:5678:9abc:def0::2 dev eth2 The first command goes to /etc/sysctl.conf to enable it after a reboot. But where do I put the "ip -6 neigh add proxy"? Best regards Franz

Hallo, for using the ipv6 neighbor functions, I have to execute commands like ip -6 neigh add proxy 2001::211:d8ff:fe97:3273 dev eth0 to publish the ip of computers in the subnet. To execute them on reboot, I have included these commands in /etc/rc.d/rc.local Also after each restart of the network, I have to execute these commands too. So: how can I always execute /etc/rc.d/rc.local

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 >

Hello, mtx and therefor amanda use generic device /dev/sg<x> for tape changer. These devices change on reboot. How to make them persistent? /dev/sch0 and /dev/sch1 seem to be persistent. /dev/tape/by-id/ shows links from WWID to generic device An UDEV rule could help? I have not found any example. -- Viele Gr??e Helmut Drodofsky Internet XS Service GmbH He?br?hlstra?e 15 70565

our new Server with AMD EPYC and super micro board reboots ramdonly. There is no error message before the reboot in /var/log/messages. we are running 2 Server with VMWare workstation without any problem.

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
