I have a static IPv4 address from CenturyLink (x.y.z.198). To find my corresponding IPv6 6rd address I need to convert my IPv4 address to hex and append CenturyLink’s 6rd prefix.
My ipv4 address: x.y.z.198
My IPv6 6rd address: XX:YY:ZZ:C6
where XX (in hex)=x (in decimal)
Prepending CenturyLink’s IPv6 6rd prefix (2602::/24) to my 6rd address leaves me with 2602:00XX:YYZZ:C600::
Today, Ubuntu 12.04.1 (GNOME Classic) was giving me this error when unmounting and SSHFS drive: “mount disagrees with the fstab.”
The SSHFS syntax has changed a bit recently. I modified my fstab to the syntax below and all is well.
USER@SERVER:/path/to/project /mnt/server fuse.sshfs user,noauto,transform_symlinks,idmap=user 0 0
I turned up a 7Mbps DSL connection with CenturyLink this evening. Here’s the configuration I used to get the circuit working. The ‘debug ppp authentication command’ helped a lot, too.
Note: To get the username and password I had to call CenturyLink technical support. The CenturyLink provisioned modems must have some mechanism to get the necessary information automatically.
