How to make scp to use ipv6 addresses?
By David Jones •
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 knownWith scp all I ever get is
ssh: Could not resolve hostname : Name or service not knownusing this I get a login into my box without a hitch

scp requires some special syntax. The IPv6 address must be enclosed in brackets, which must then be escaped. So in your example it would look like this:
scp -6 osis@\[2001:db8:0:1\]:/home/osis/test.file ./test.fileOtherwise the first colon ':' is thought to be the separator between the file and the address parts which would result in
ssh: Could not resolve hostname 2001: Address family for hostname not supportedIn your example with the ip ::1 it is interpreted as if you want to ssh to the host '' (blank).
The above command didn't work for me, the error I got was due to v6 address was allowed taking for path.
No need to use back slash "\" . As per the above example below command will work.
scp -6 osis@[2001:db8:0:1]:/home/osis/test.file ./test.file
