| | 1 | DNS SRV record support in apt |
| | 2 | ============================= |
| | 3 | |
| | 4 | Apt supports a subset of the DNS SRV server records protocol as |
| | 5 | described in RFC 2782 for service discovery. |
| | 6 | |
| | 7 | Before connecting to the requested server APT will send a SRV |
| | 8 | record request of the form "_$protocol._tcp._$host", e.g. |
| | 9 | "_http._tcp.ftp.debian.org" or "_http._tcp.security.debian.org". |
| | 10 | |
| | 11 | If the server sends SRV records |
| | 12 | as a reply APT will use those to connect to the server(s) in |
| | 13 | this reply. It will honor the "priority" field in the reply. |
| | 14 | |
| | 15 | However it does not implement the "weight" alogrithm as described |
| | 16 | in RFC 2782. It will use an equal weight for each server of the |
| | 17 | same priority. |
| | 18 | |
| | 19 | If connecting to a server fails APT will retry with the next one |
| | 20 | and remove the server from the list of valid servers for this |
| | 21 | session. |
