## Troubleshooting
### See What BATMAN Thinks Is On The Mesh
Use `batctl dc` to view the distributed ARP table. This is a quick way to confirm which nodes/clients are currently visible on the mesh, along with their IPs and “last seen” time (and, after hostname propagation, their hostnames):
```sh
root@manet01:~# batctl dc
[B.A.T.M.A.N. adv 2024.3-openwrt-6, MainIF/MAC: wlan0/2c:c6:82:8a:2b:ca (bat0/9a:c2:84:47:71:98 BATMAN_V)]
Distributed ARP Table (bat0):
IPv4 MAC VID last-seen
* 10.41.0.1 manet01_br-ahwlan -1 0:09
* 10.41.88.231 manet02_br-ahwlan -1 1:54
* 10.41.0.111 0e:12:80:92:f7:dc -1 0:39
* 10.41.254.229 manet03_br-ahwlan -1 0:38
```
In the output above, entries ending in `_br-ahwlan` are mesh nodes; entries shown as raw MAC addresses are typically end user devices behind a node.
### Browse mDNS Services
Use `avahi-browse -a` to see mDNS-advertised hostnames and services currently visible on the mesh:
```sh
root@manet01:~# avahi-browse -a
+ br-ahwlan IPv6 manet02 _ssh._tcp local
+ br-ahwlan IPv4 manet03 _ssh._tcp local
+ br-ahwlan IPv4 manet02 _ssh._tcp local
+ br-ahwlan IPv6 manet02 _http._tcp local
+ br-ahwlan IPv4 manet03 _http._tcp local
+ br-ahwlan IPv4 manet02 _http._tcp local
+ br-ahwlan IPv6 manet02 [c6:2a:60:bd:a5:6e] _workstation._tcp local
+ br-ahwlan IPv4 manet03 [b2:95:f1:69:d9:0a] _workstation._tcp local
+ br-ahwlan IPv4 manet03 [b8:27:eb:6c:45:ac] _workstation._tcp local
+ br-ahwlan IPv4 manet02 [c6:2a:60:bd:a5:6e] _workstation._tcp local
+ br-ahwlan IPv6 MacBook Air (3) _companion-link._tcp local
+ br-ahwlan IPv4 MacBook Air (3) _companion-link._tcp local
+ br-ahwlan IPv6 7A55CB537445@MacBook Air (3) _raop._tcp local
+ br-ahwlan IPv4 7A55CB537445@MacBook Air (3) _raop._tcp local
+ br-ahwlan IPv6 MacBook Air (3) _airplay._tcp local
+ br-ahwlan IPv4 MacBook Air (3) _airplay._tcp local
```
