You mean that both client and server are running on the same machine?

comment Use IPtables or null route for blacklisting about 1 million IP addresses?
It would help a lot to know why you want to block this many addresses, and wether you want to filter INPUT or FORWARD traffic.

comment Multicast IP Addresses
@Nils, I don't know all Cisco switches to make a reliable statement, but most certainly the answer is No. Multicast IPs and Multicast MACs are separate things, it is the operating system job in hosts and routers to create and assign Multicast MACs to alleviate the load in the link-layer when Multicast IP is being used.

comment My own IPv6 tunnel
"a load of IPv6 addresses" is way too vague. You must at least specify if it is a /64 or bigger allocation. This changes everything.

comment How to copy public private key to linux
@alharaka The point of using passphrase-protected keys is so that if either the key or the passphrase is stolen, it will only result in a partial compromise, which doesn't give the thief access to the system. With the passphrase set, you have time to revoke the key before the attacker has full access to the system. But having a key in a USB stick and plugging it in any computer you may not trust is inherently dangerous practice. You may have an emergency one-time key in a USB stick, that you revoke as soon as you have to use it once.
