# WHATPORT(3260)

## NAME

port 3260 — iSCSI target — iSCSI — raw SCSI block storage over TCP, the port every SAN target listens on.

Protocol: TCP  
IANA registry

## DESCRIPTION

TCP 3260 is the IANA-registered iSCSI target port from RFC 7143: initiators open a session, log in with a target IQN and then issue SCSI commands over TCP, treating a remote LUN as a local disk. Every common target implementation defaults here — Linux LIO, tgt, NetApp, Synology and QNAP appliances, and cloud block-storage gateways. On a scan it means someone's disks are on the network, and an unauthenticated target will hand its LUN list to anyone who asks.

## EXPOSURE

**Do not expose.** iSCSI carries block data in cleartext and its CHAP authentication is optional and weak; put it on a dedicated storage VLAN, never on a routed or public interface.

## CHECK

```sh
iscsiadm -m discovery -t sendtargets -p TARGET:3260
```
