I don't see how this will solve a bandwidth issue, but this is the answer to your question:
The 'ip' command will allow you to set multiple IP addresses on a single interface, whereas the 'ifconfig' command will replace an existing IP address with a specified new address.
So to add multiple address to an interface, use:
Code:
ip address add 192.168.1.1/24 dev eth0
ip address add 4.2.2.2/28 dev eth0
And don't forget to bring the link up:
Code:
ip link set eth0 up
To delete an IP address from the interface, replace "add" with "delete".

Hi everyone,
I have a quick/newb question:
I know that a public key is used to encrypt data and a private key is used to decrypt data but who keeps the public/private keys??
Does the Web Server hold both?
Does the Web Server have the public key and does the client have the private key? ... (3 Replies)
Hi All,
I have a query....say on server A, I have generated the Private and Public keys and shared the public key with server B.

Hi,
What tool is used to generate public and private keys for SCP?
Do you have an example script that generates these keys, puts them in files and then another example script that references them from SCP?
Thanks, (9 Replies)
Hi All,
I have a requirement where i need to check if an rsa public key corresponds to a private key and hence return success or failure. Currently i am using the command

ifndp-proxy
IFNDP-PROXY(5) Network configuration IFNDP-PROXY(5)NAME
ifndp-proxy[-<interface name>] - IPv6 NDP and IPv4 ARP proxy entries
SYNOPSIS
/etc/sysconfig/network/ifndp-proxy
/etc/sysconfig/network/ifndp-proxy-<interface name>
DESCRIPTION
These files contain IPv6 NDP and IPv4 ARP proxy settings, that should be applied using the ip neigh add proxy command documented in the
ip(8) manual page that provides a common interface for IPv4 and IPv6.
The NDP/ARP proxy is required, e.g. when IP addresses from the same subnet have to be used on the interface of the host as well as on
interfaces behind a (tunnel) interface and using a bridge is not an option.
Don't forget to enable forwarding and the NDP/ARP proxy by setting
net.ipv6.conf.<all|default|interface name>.proxy_ndp = 1
net.ipv6.conf.<all|default|interface name>.forwarding = 1
and/or
net.ipv4.conf.<all|default|interface name>.proxy_arp = 1
net.ipv4.conf.<all|default|interface name>.forwarding = 1
or
net.ipv4.ip_forward = 1
either as global all setting in the /etc/sysctl.conf file or using the ifsysctl(5) files, that allow per-interface setup.
Forwarding can be also enabled in the /etc/sysconfig/sysctl file using the IP_FORWARD and IPV6_FORWARD variables.
The proxy entries are added and deleted using the if-{up|down}.d/ndp-proxy script, every time after an involved interface has been set
up or down.
SYNTAX
The format of the ifndp-proxy file is:
<address> <address interface> <proxy interface list>
The format of the ifndp-proxy-<address interface> file is same to above, but allows also to omit the address interface by using a "-" as
placeholder inside of the file, because it is already available in the file name:
<address> <address interface | -> <proxy interface list>
Lines beginning with # and blank lines are ignored.
Each line defines to add a proxy NDP/ARP entry with the address of or behind address interface to all interfaces in the proxy interface
list.
EXAMPLES
Let's assume, your machine is connected via eth0 to a switch with the networks 2001:db8:abba::/64 and 192.168.100.1/24 and is using the IP
address 1 itself. You'd like to use the addresses 11 and 12 e.g. for virtual machines behind the tap1 and tap2 interface, that is:
2001:db8:abba::1/64 -- local eth0 address
2001:db8:abba::11/64 -- address behind tap1
2001:db8:abba::12/64 -- address behind tap2
192.168.100.1/24 -- local eth0 address
192.168.100.11/24 -- address behind tap1
192.168.100.12/24 -- address behind tap2
then set up the following entries in the ifndp-proxy file:
2001:db8:abba::1 eth0 tap1 tap2
2001:db8:abba::11 tap1 eth0 tap2
2001:db8:abba::12 tap2 eth0 tap1
192.168.100.1 eth0 tap1 tap2
192.168.100.11 tap1 eth0 tap2
192.168.100.12 tap2 eth0 tap1
additionally to the routing entries in the routes or ifroute-<interface name> files.
