When I try to use scp over IPv6 addresses I get this:

scp -6 osis@::1:/home/osis/test.file ./test.file ssh: Could not resolve hostname : Name or service not known

using ssh osis@::1 i get login into my box without a hitch

With scp all I ever get is ssh: Could not resolve hostname : Name or service not known

You need some brackets in your command:

scp -6 osis@\[::1\]:/home/osis/test.file ./test.file

Otherwise the first ':' symbol is thought to be the separator between the file and the address parts and it thinks you want to ssh to '' blank.

thank you for your answer, this info was somehow missing from man scp;man ssh –  Osis Nov 22 '10 at 14:24
Consider submitting an updated man page, then you can say: I helped. –  Martin Owens -doctormo- Nov 22 '10 at 17:26
When using the -6 flag, you can just type localhost instead of ::1 (which is the IPv6 Address for localhost) to avoid the brackets and therefore any need to escape something on the shell: scp -6 osis@localhost:/home/osis/test.file ./test.file –  freddyb Apr 30 '11 at 16:22
