I am an intermediate user, and I am trying to get everything set up so that I may connect to my home desktop remotely via SSH. Since I am given a DHCP address by my ISP, I was going to use IPv6 (along with the '-6' flag) to connect because it appears to be based on my MAC address.

My problem is that when I try to connect via SSH with a command like:

ssh -l user -6 IPv6_address

or:

ssh -6 user@IPv6_address
(where user is my username on the remote machine, and IPv6_address is the remote machines IPv6 address)
I get the following error message:

ssh: connect to host IPv6_address port 22: Invalid argument


Thus I have decided that I must not understand what parts of the address mean what. I cannot even begin to convey how much I would appreciate it.

Thanks.


P.S. I used ifconfig to find my IPv6 address.

1. The IPv6 based on your MAC address is link-local. You have zero chance to have it visible from anywhere not on the same Ethernet segment.
2. As far as I understand, you have no other IPv6 addresses by default. That means that your provider doesn't provide you global IPv6 connectivity. For what you want to do you need global IPv6 connectivity.
3. If you have 2 systems without external (globally routable) IPv4 addresses any solution requires an external party that will help you with data transfer. There are some so-called "tunnel brokers", who let you connect to them, give you an IPv6 address and allow you get and send the data over IPv6 in encapsulated form via the tunnel.
4. I can name at least go6.net (Hexago is the company providing this service) and http://broker.aarnet.net.au/ as two services I have used successfully.
5. Additionally, you would better know that sometimes IPv6 addresses have tp be enclosed in [ ] for distinguishing : in address from port separator.
6. Try using some free DNS service, like freedns.afraid.org, to write symbolical names in commands, not random hex data

Though disappointed, I am quite thankful for the help, so thanks.

Here's a very good IPv6 overview and deployment guide:

A quick five-minute solution that will get you up and running with a IPv6 address is to register with Hurricane Electric's IPv6 tunnelbroker service.

You will receive a /64 to run on your local network along with a /64 for the link back to Hurricane Electric. The setup for Linux is very simple:
Just use the IP's provided by the web site. Once that's done you are up and running.

Enjoy!
