# WHATPORT(7007)

## NAME

port 7007 — AFS Basic OverSeer Server (bosserver) — The AFS BOS Server — the process that starts, stops, and restarts every other AFS server daemon.

Protocol: TCP/UDP  
IANA registry

## DESCRIPTION

IANA registers 7007 as afs3-bos, the basic overseer process. bosserver runs on every AFS file and database server, reads BosConfig to know which daemons to keep alive, and answers `bos` commands to start, stop, restart, and salvage them. It is the control plane of an AFS cell: whoever can issue authenticated bos commands controls what runs on the server. Like the rest of AFS it uses Rx over UDP.

## EXPOSURE

**Do not expose.** This is remote process control for the whole cell; restrict it to the AFS server network and rely on Kerberos-authenticated admin principals, never on reachability alone.

## CHECK

```sh
bos status TARGET -noauth
```
