# Networking: dhclient: DHCPDISCOVER on eth0 ... No DHCPOFFERS received. No working leases in persistent database - sleeping.

**Code:** `DHCPDISCOVER ... No DHCPOFFERS received` · **Category:** Networking · **Seen on:** Linux, Networking

The client broadcast a DHCP request and no server answered.

## Meaning

Same causes as 169.254 but from the Linux side: no DHCP server on the VLAN, a missing relay, cable/Wi-Fi isolation, MAC filtering, or DHCP snooping blocking offers. Capture with `tcpdump -ni eth0 port 67 or port 68` to see whether the DISCOVER leaves and any OFFER returns.

## Common causes

- No DHCP server reachable on this VLAN
- DHCP relay/ip helper missing
- Switch DHCP snooping or port security blocking
- MAC filtering on the server
- Link flapping at boot

## Quick fix

1. Watch the exchange: `sudo tcpdump -ni eth0 port 67 or port 68`
2. Check the server logs and scope
3. Fix relay/VLAN, or set a static IP temporarily

## Detailed fix by platform

### Linux

1. 

```bash
sudo dhclient -v eth0
sudo tcpdump -ni eth0 port 67 or port 68
```


## How to diagnose

1. **DISCOVER** — Sent?
2. **OFFER** — Received?
3. **Relay/VLAN** — Correct?
