### <a name="troubleshooting"></a>Troubleshooting
|
|
|
|
The command:
|
|
|
|
weave status
|
|
|
|
reports on the current status of various Weave Net components, including
|
|
DNS:
|
|
|
|
```
|
|
...
|
|
Service: dns
|
|
Domain: weave.local.
|
|
Upstream: 8.8.8.8, 8.8.4.4
|
|
TTL: 1
|
|
Entries: 9
|
|
...
|
|
```
|
|
|
|
The first section covers the router; see the [troubleshooting
|
|
guide](/site/troubleshooting.md#weave-status) for more details.
|
|
|
|
The 'Service: dns' section is pertinent to weaveDNS, and includes:
|
|
|
|
* The local domain suffix which is being served
|
|
* The list of upstream servers used for resolving names not in the local domain
|
|
* The response ttl
|
|
* The total number of entries
|
|
|
|
You may also use `weave status dns` to obtain a [complete
|
|
dump](/site/troubleshooting.md#weave-status-dns) of all DNS registrations.
|
|
|
|
Information on the processing of queries, and the general operation of
|
|
weaveDNS, can be obtained from the container logs with
|
|
|
|
docker logs weave
|
|
|
|
### <a name="limitations"></a>Present Limitations
|
|
|
|
* The server will not know about restarted containers, but if you
|
|
re-attach a restarted container to the weave network, it will be
|
|
re-registered with weaveDNS.
|
|
* The server may give unreachable IPs as answers, since it doesn't
|
|
try to filter by reachability. If you use subnets, align your
|
|
hostnames with the subnets.
