Description
Although our best practice advises end users to not run other software on the same machine as their Couchbase instances, there's a number of reasonable valid use cases such as monitoring agents and backup utilities which are colliding with our port numbers.
Search for a Couchbase default network port such as 8091 on IANA - http://www.iana.org/assignments/service-names-port-numbers/service-names-port-numbers.xhtml?search=8091 and you'll see we're using network ports registered to other services.

| Port Number | Registered | Colliding | Couchbase Description |
| 8091 | Yes | Yes | Used by the Couchbase Web Console for REST/HTTP traffic. |
| 8092 | No | No | Used to access views, run queries, XDCR and update design documents. |
| 8093 | No | No | Used by query services for REST/HTTP traffic. |
| 8094 | No | No | External HTTP port for the Search service |
| 9100 | Yes | Yes | Internal index admin port (-adminPort). |
| 9101 | Yes | Yes | Internal index scan port (-scanPort). |
| 9102 | Yes | Yes | Internal index HTTP port (-httpPort). |
| 9103 | Yes | Yes | Internal index build port (-streamInitPort). |
| 9104 | Yes | Yes | Internal index build port (-streamCatchupPort ). |
| 9105 | Yes | Yes | Internal index maintenance port (-streamMaintPort). |
| 9998 | Yes | Yes | Internal REST port. |
| 9999 | Yes | Yes | Internal GSI port used by the internal administrators. |
| 11207 | No | No | Used by smart client libraries to access data nodes using SSL. This is a memcached SSL port. |
| 11209 | No | No | Internal Bucket Port. |
| 11210 | No | No | Used by smart client libraries or Moxi to directly connect to the data nodes. The XDCR client uses this port as well as the SDKs. This is a memcached port. |
| 11211 | Yes | No | Used by pre-existing Couchbase Server and memcached (non-smart) client libraries (such as Moxi). |
| 11214 | No | No | Used for SSL XDCR data encryption. |
| 11215 | No | No | Used for SSL XDCR data encryption. |
| 18091 | No | No | Used by the Couchbase Web Console for REST/HTTP traffic with SSL. |
| 18092 | No | No | Used to access views, run queries, XDCR and update design documents with SSL. |
| 18093 | No | No | N1QL SSL port |
| 4369 | Yes | No | Erlang Port Mapper ( epmd ) |
| 21100 to 21299 (inclusive) | No | No | Node data exchange. |
| 6060 | No | No | Used internally on the local host. Not used for communication between cluster nodes |
| 11213 | No | No | Used internally on the local host. Not used for communication between cluster nodes |
Anything which is not registered and not colliding we should register with IANA, anything that is already colliding we should look to move the port to an unused space and register it for our use.
I will make sub-tasks for this for each Couchbase component which is affected.
