# Troubleshooting

## Unknown bpf_trace_printk
|
|
|
|
```console
|
|
invalid argument: unknown func bpf_trace_printk
|
|
```
|
|
|
|
Solution:
|
|
|
|
Compile dae with CFLAG `-D__REMOVE_BPF_PRINTK`. See [build-by-yourself](build-by-yourself.md).

## Binding to WAN but no network
|
|
|
|
### Troubleshoot local DNS service
|
|
|
|
If you use `adguardhome`, `mosdns` in `dns` section, refer to [external-dns](external-dns.md).
|
|
|
|
### Troubleshoot firewall
|
|
|
|
If you bind to wan, make sure firewall is stopped or `12345` is allowed by firewall. Don't worry about the security of this port because this port has its own firewall rule.
|
|
|
|
Usual firewalls on Linux:
|
|
|
|
```bash
|
|
ufw
|
|
firewalld
|
|
```
|
|
|
|
### Troubleshoot PPPoE
|
|
|
|
dae does not support PPPoE yet. We are working on it. However, binding to LAN for other machines should work fine.
|
|
|
|
## Binding to LAN but bad DNS in other machines
|
|
|
|
### Troubleshoot config of dae
|
|
|
|
Make sure you have bind to the correct LAN interfaces.
|
|
|
|
For example, if your use the same interface eth1 for WAN and LAN, write it as `wan_interface: eth1` and also in `lan_interface: eth1`. If the LAN interfaces you want to proxy are eth1 and docker0, write them both as `lan_interface: eth1,docker0`.
|
|
|
|
### Troubleshoot DNS
|
|
|
|
To verify on another machine in LAN:
|
|
|
|
```bash
|
|
curl -i 1.1.1.1
|
|
curl -i google.com
|
|
```
|
|
|
|
If the first line has a response and the second line doesn't, check whether port `53` is occupied by others on dae's machine.
|
|
|
|
```bash
|
|
netstat -ulpen|grep 53
|
|
# or
|
|
# lsof -i:53 -n
|
|
```
|
|
|
|
If does, stop the service process or change its listening port from 53 to others. Do not forget to modify `/etc/resolv.conf` to make DNS accessible (for example, with content `nameserver 223.5.5.5`, but do not use `nameserver 127.0.0.1`).
