Matthias Radestock cf9c479727 check that the go stdlib was built with the required options 
AFAICT, go build tags are a compile-time only construct, so there is
no way to query whether a certain package was built with a specific
tag. However, the 'netgo' tag triggers conditional compilation of the
cgo_stubs.go file, and that file name ends up in the executable. (we
could have looked for specific symbols in the 'net.a' library instead,
but that requires locating it first, which is more hassle than it is
worth)

Matthias Radestock 7b02365de8 make dns resolution work in weave container 
by using go's internal DNS resolver.

NB: this relies on go's std library having been compiled with the
netgo build tag, e.g.

   sudo go install -tags netgo -a std

David Wragg c4c06a2dc0 Don't use /tmp for big files 
/tmp is on tmpfs on some systems, so it's better to use /var/tmp
for large files.

David Wragg 89fa310c00 Provide a way to bypass the use of sudo 
It's not necessary to be root to run "docker" commands, if your
user is in the "docker" group.

Matthias Radestock e7e7de2173 check whether a container has died with docker rather than ps 
since that means one less dependency on running 'weave' in the same
namespace as docker

David Wragg cb0541078a Route multicast packets across the weave network 
Add a route to send multicast packets to ethwe and so across the weave
network.

Without that, multicast packets get sent to the default route, i.e.
to docker's eth0 interface, rather than across the weave network.
So IP multicast doesn't work between containers on different hosts,
even though weaver supports it.

Bryan Boreham c48ae19c55 Tidy up messages; ensure errors to to stderr 2014-09-18 11:47:47 +01:00
Bryan Boreham a75a0d8709 If and only if network setup because the container died, say so. 
This involves capturing stderr output from all the 'ip' commands so we
can hide that output if we see the process died, or show it to the user
if the process didn't die, in which case we don't know why we failed.

Bryan Boreham bfd5007339 Don't test if symlink exists before 'rm -f' 
When the symlink's target doesn't exist, '[ -f' is false, so the symlink doesn't get removed.
Since we do always want it to be removed, just call 'rm -f' anyway, which won't complain
if the file doesn't exist.
