I have created a bonding bond1 interface with 6 Eth , mode=4. Recently i have changed my old ipv6 to new one and tried to restart as well as reload network service. Post which i can see old as well as changed ipv6 in ifconfig command output.
You haven't said which system you use but from the output format i suppose it is some Linux-derivate.
It is common to configure network interfaces in via scripts/scriptlets in /etc/sysconfig/... but i suppose (part of) your configuration (the old part) is/was also duplicated in some other part of the system initialisation, probably in some rc-script somewhere in /etc/rc.d. Perhaps this didn't show p because the two competing configurations were effectively the same. Now that you have changed one of them they create two different configurations.
If this is the case you should simply remove that other configuration and rely on /etc/sysconfig and the procedures using it.
Hi gurus,
In a few month, we must enable IPv6 on our Linux Server!
Should we reinstall the Linux machine to enable IPv6 or could we just make some change in configuration's files?
Could Linux run simultaneous IPv4 and IPv6?
Thanks in advance for our help our ideas?
Best regards,

Hi, anyone has had experience in a static setting an IPv6 interface?, I'm trying accordance with the admin guide (ipv6 network configuration tasks), configure one interface in the server, actually i can do ping to my default gateway and access the Internet in IPv6, the specific point is however,...

Hi,
Apologies if this is the wrong forum or this question has been answered already.
I'm using the ISC dhcpd server on Centos 6.0, and can happily assign a single IPV6 address to a client with entries like this:
subnet6 fd01:0:0:5::/64

option dhcp6.name-servers fd01:0:0:5::226;... (0 Replies)
Hi,
Can any one please help me increase the arp stale time of an ipv6 interface on linux platform ?
I have tried increasing the variable gc_stale_time but that doesnt work.

Hello all,
I am trying to receive (tcp/udp/sctp) traffic from all IPs and, eventually, all ports of an IPv6 address block using as few sockets as possible short of implementing my own network stack.
One possible solution was to associate an IP block to an interface then bind to that... (6 Replies)
HI all,
First post on the forum, and my first proper project on the Paspberry Pi, so sorry if this is in the wrong place.
I am trying to turn my Pi in to a 3G/4G Bonding router. I have been researching and trying this for a week or so now. The basic plan is to have up to 6 ZTE MF823 USB... (0 Replies)
Hello Dears ,
please I need your support I have Oracle Solaris 10 X86 server please if you can advise how can I add IP v6 on my server and if IPv6 was disabled how can i enable it also how can i add two IP (v4 and v6) on the same interface or I have to add another interface .
Thanks in... (1 Reply)
I'm running a Linux OS that uses Debian as it's base. A commercial vpn is installed that uses OpenVPN. For some reason, I can't get ipv6 to tunnel properly .... and Ipleak.net shows that my location is being unmasked by ipv6.
I've tried kernel commands at boot, I've tried sysctl.conf commands.... (2 Replies)

ifsysctl
IFSYSCTL(5) Network configuration IFSYSCTL(5)NAME
ifsysctl[-<interface name>] - per network interface sysctl settings
SYNOPSIS
/etc/sysconfig/network/ifsysctl
/etc/sysconfig/network/ifsysctl-<interface name>
DESCRIPTION
These files are intended to contain sysctl settings, that should be applied when a network interface is created. This are usually interface
specific settings, like:
net.ipv6.conf.eth0.use_tempaddr = 1
or
net.ipv4.conf.eth0.rp_filter = 0
The settings are applied by the /etc/sysconfig/network/scripts/ifup-sysctl script executed via /etc/udev/rules.d/77-network.rules rule (see
udev(7)), after the creation and after the rename of the interface name to its persistent name (when applicable), but before the ifup
<interface name> -o hotplug may be executed to configure the interface.
The settings are not applied by default when the NetworkManager is active (NETWORKMANAGER=yes), except when the IFSYSCTL_NETWORKMANAGER=yes
variable is set in the /etc/sysconfig/network/config file.
Settings from the ifsysctl- file are applied every time an interface has been created.
Settings from the ifsysctl-interface name file are applied when the interface with the corresponding interface name has been created.
SYNTAX
The sysctl(8) utility is required to apply the settings. It supports two separator characters for sysctl keywords: a "." in default format
and a "/" in the alternate format. Therefore the syntax is basically same to the /etc/sysctl.conf file.
Interface names may contain a ".". In the default sysctl format using a "." as separator, that is any "." in the interface name of the key-
word, has to be replaced with a "/". In the alternate sysctl format with "/" as separator, normal interface names can be used.
Optionally, the ifsysctl files may contain also the $INTERFACE and the $SYSCTL_IF variables, that are automatically replaced with the cur-
rent interface name usable in the alternate format and with the sysctl-quoted interface name for the default format, before the settings
are passed to the sysctl utility.
Note also, that settings with variables in the ifsysctl (without the -<interface name> suffix), will be applied for every interface!
Further, files with variables are not compatible to the /etc/sysctl.conf file.
EXAMPLES
Settings for "eth0" and "eth0.1" interfaces
# using "." as separator:
net.ipv6.conf.eth0.use_tempaddr = 1
net.ipv6.conf.eth0/1.use_tempaddr = 1
# using "/" as separator:
net/ipv6/conf/eth0/use_tempaddr = 1
net/ipv6/conf/eth0.0/use_tempaddr = 1
Settings with variables:
# using "." as separator:
net.ipv6.conf.$SYSCTL_IF.use_tempaddr = 1
# using "/" as separator:
net/ipv6/conf/$INTERFACE/use_tempaddr = 1
To test your ifsysctl-eth0 or ifsysctl file, use:
/etc/sysconfig/network/scripts/ifup-sysctl eth0 -o debug
