           Summary: literal IPv6 addresses not supported in ssh protocol
           Product: rsync
           Version: 2.6.9
          Platform: All
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P3
         Component: core
        AssignedTo: wayned at samba.org
        ReportedBy: david.madore at ens.fr
         QAContact: rsync-qa at samba.org


It seems that literal IPv6 addresses are supported in rsync:// URI's (this was
bug 1675, which is now fixed), but not in ssh.  For example, compare the
following behavior of rsync and scp:

vega david ~ $ rsync -av '[fe80::213:d4ff:fee9:3951%eth1]:./empty' /tmp/
ssh: fe80::213:d4ff:fee9:3951%eth1]: Name or service not known
rsync: connection unexpectedly closed (0 bytes received so far) [receiver]
rsync error: unexplained error (code 255) at io.c(463) [receiver=2.6.8]
vega david ~ $ scp -p '[fe80::213:d4ff:fee9:3951%eth1]:./empty' /tmp/
Password:
empty                                         100%    0     0.0KB/s   00:00
vega david ~ $ ssh fe80::213:d4ff:fee9:3951%eth1
Password:
Linux neptune 2.6.16-2-k7 #1 Sat Jul 15 23:05:41 UTC 2006 i686
<...>

Here I used link-local IPv6 addresses with a scope identifier just to emphasize
(and also because you don't need real IPv6 connectivity or any kind of setup to
test this), but it doesn't work any better with (non-scoped) global addresses:

vega david ~ $ rsync -av '[2001:7a8:7171:37:213:d4ff:fee9:3951]:./empty' /tmp/
ssh: 2001:7a8:7171:37:213:d4ff:fee9:3951]: Name or service not known
rsync: connection unexpectedly closed (0 bytes received so far) [receiver]
rsync error: unexplained error (code 255) at io.c(463) [receiver=2.6.8]
vega david ~ $ scp -p '[2001:7a8:7171:37:213:d4ff:fee9:3951]:./empty' /tmp/
Password:
empty                                         100%    0     0.0KB/s   00:00

This is with rsync version 2.6.8, but I also tried with today's CVS.

I'd be really glad if this were fixed (especially for scoped ll addresses, as
there's no way to register them in DNS, so they *must* be literal, and in some
cases, when DHCP is out of order or something, ll IPv6 is the best kind of
connection one can achieve!).

I emphasize that this is not a dup of bug 1675.

Happy hacking!
