# Port in use (connman)
|
||
|
|
|
||
|
|
## Problem
|
||
|
|
|
||
|
|
When trying to run DNS thing, `connman` is already using port 53.
|
||
|
|
|
||
|
|
```bash
|
||
|
|
docker compose up --detach --build --remove-orphans
|
||
|
|
[+] Running 0/1
|
||
|
|
⠿ Container pihole Starting 0.2s
|
||
|
|
Error response from daemon: driver failed programming external connectivity on endpoint pihole (bc535387671f0d471f11f8ade5eedc4771126c057e2099931e8ef49461111149): Error starting userland proxy: listen tcp4 0.0.0.0:53: bind: address already in use
|
||
|
|
```
|
||
|
|
|
||
|
|
## Solution
|
||
|
|
|
||
|
|
- Find the `connman.service` file:
|
||
|
|
|
||
|
|
```bash
|
||
|
|
grep -Ril "connman" /etc/systemd/
|
||
|
|
```
|
||
|
|
|
||
|
|
- Add `--nodnsproxy` to the `ExecStart` line:
|
||
|
|
|
||
|
|
```bash
|
||
|
|
ExecStart=/usr/sbin/connmand -n --nodnsproxy
|
||
|
|
```
|
||
|
|
|
||
|
|
- Reload and restart stuff:
|
||
|
|
|
||
|
|
```bash
|
||
|
|
systemctl daemon-reload
|
||
|
|
systemctl restart connman.service
|
||
|
|
```
|
||
|
|
|
||
|
|
- Try your thing again. For example:
|
||
|
|
|
||
|
|
```bash
|
||
|
|
docker compose up -d --remove-orphans
|
||
|
|
```
