REGISTERED PORT NUMBERS
The Registered Ports are not controlled by the IANA and on most
systems can be used by ordinary user processes or programs executed by
ordinary users.
Ports are used in the TCP [RFC793] to name the ends of logical
connections which carry long term conversations. For the purpose of
providing services to unknown callers, a service contact port is
defined. This list specifies the port used by the server process as
its contact port. While the IANA can not control uses of these ports
it does register or list uses of these ports as a convienence to the
community.
To the extent possible, these same port assignments are used with the
UDP [RFC768].
The Registered Ports are in the range 1024-65535.

SUN RPC NUMBERS
To obtain SUN Remote Procedure Call (RPC) numbers send an e-mail
request to "rpc@sun.com".
The RPC port management service ('portmap' in SunOS versions less than
5.0 and 'rpcbind' in SunOS versions greater than 5.0) "registers" the
IP port number that is allocated to a particular service when that
service is created. It does not allocate ports on behalf of those
services.
For an exact specification of the semantics refer to the source code
of svcudp_create() and svctcp_create() in the archives. In short
however is that these interfaces, and svc_tli_create their Transport
Independent RPC equivalent, take either a user specified port number
or RPC_ANY (-1) which effectively means "I don't care." In the "I
don't care" case the create code simply calls socket(2) or t_open(3n)
which allocates an IP port based on the rules:
if euid of the requesting process is 0 (i.e., root)
allocate the next available port number in the
reserved port range.
else
allocate the next available port in the non-reserved
range.
Port numbers count up sequentially.
Can a port that is "assigned" can be used when the assignee's service
is not present? Say port 501 is assigned to the "jeans" service. On
a machine that does not have the "jeans" service, nor has any clients
that might be expecting to use it, is port 501 available for other
uses? Any dynamic allocation process, like the portmapper, that
chooses the next unused port might allocate port 501 dynamically to a
process that asked for a "I don't care" port. So any dynamic
allocation scheme may pick an unused port that happened to correspond
to a port number that had been "assigned" but was currently unused.
While it might be desirable, it is impossible to guarantee that any
unused port, even though officially assigned to a service, is not
picked by a dynamic allocator since such an assignment might occur
long after the delivery of the system into a site that doesn't watch
for the latest list.
There is the restriction that only "superuser" on BSD derived systems
such as SunOS can bind to a port number that is less than 1024. So
programs have used this information in the past to identify whether or
not the service they were talking to was started by the superuser on
the remote system. Making this assumption is dangerous because not
all system enforce this restriction.
Sun RPC services use ports that are currently unused. If someone
noted that an RPC service was using port 781, it would be just as
happy using port 891, or 951. The service doesn't care what port it
gets, remote clients will query the portmapper to ask it what port
number was assigned to the service when it was started. The key is
that the port was not currently in use. The only port that ONC/RPC
must have is 111 its assigned port for the portmap service.
The most common complaint comes when people put a new service on their
system. When they configure their systems they put the new service
configuration commands at the end of their system startup scripts.
During startup, several network services may be started. Those
services that are ONC/RPC based just pick the next available port,
those that have pre-assigned ports bind to their pre-assigned port.
Clearly the correct sequence is to have all services that need a
particular port to be started first (or if they are "latent" services
that are started by inetd, to have inetd started). Finally, the RPC
services should be started as they will be assigned unused ports. (In
the BSD networking code (which we use) the algorithm for picking
ports is in the file in_pcb.c, function in_pcbbind().)
Services should be started in this order:
a) Services that will "run" continuously and have an assigned
port. Note that this includes rpcbind (nee portmap) that has
port 111 assigned to it.
b) inetd - which will automatically create sockets for those
services that have reserved ports but only run on demand
(like finger)
c) RPC services - which will automatically pick unused ports and
maximize efficiency of the "IP Port" namespace.
The include file /usr/include/netinet/in.h defines a constant
IPPORT_RESERVED to be 1024. The relevant text is:
/*
* Ports < IPPORT_RESERVED are reserved for
* privileged processes (e.g. root).
* Ports > IPPORT_USERRESERVED are reserved
* for servers, not necessarily privileged.
*/
#define IPPORT_RESERVED 1024
#define IPPORT_USERRESERVED 5000 Portmap does not allocate ports, the kernel allocates ports. The code that does this is part of nearly every UNIX system in the world (and since the BSD code is 'free' it is often the same code). RPC services ask the kernel to allocate them a port by calling the "bind()" system call. The parameter they pass is "INADDR_ANY" which means "allocate me any IP port you want". The kernel does that by looking at all of the ports that are currently in use and picking one that is not currently used. The number picked is either less that 1024 if the process is privledged, or greater than 1024 if the process is not privledged. After the kernel has allocated a port, the service registers this allocation with portmap. The portmapper is merely a registry of previously allocated ports. Note "allocated" here is being used in the sense that they are used by an open socket, not assigned a well known name. The role of /etc/services is to provide an idea to people who are looking at network traffic as to where a packet may have originated from or is headed to. For services like finger that have assigned ports, they can just hard code the port they want into their executable. (it isn't like it will change, and if they read it from /etc/services and someone had mistyped the port number it won't interoperate with clients anyway!) It is not practical to read the /etc/services file into the kernel to prevent it from giving out port numbers that are "pre-assigned", nor is it generally desirable since with the correct ordering of startup it is completely unneccesary.

IP OPTION NUMBERS The Internet Protocol (IP) has provision for optional header fields identified by an option type field. Options 0 and 1 are exactly one octet which is their type field. All other options have their one octet type field, followed by a one octet length field, followed by length-2 octets of option data. The option type field is sub-divided into a one bit copied flag, a two bit class field, and a five bit option number. These taken together form an eight bit value for the option type field. IP options are commonly refered to by this value. Copy Class Number Value Name Reference ---- ----- ------ ----- ------------------------------- --------- 0 0 0 0 EOOL - End of Options List [RFC791,JBP] 0 0 1 1 NOP - No Operation [RFC791,JBP] 1 0 2 130 SEC - Security [RFC1108] 1 0 3 131 LSR - Loose Source Route [RFC791,JBP] 0 2 4 68 TS - Time Stamp [RFC791,JBP] 1 0 5 133 E-SEC - Extended Security [RFC1108] 1 0 6 134 CIPSO - Commercial Security [???] 0 0 7 7 RR - Record Route [RFC791,JBP] 1 0 8 136 SID - Stream ID [RFC791,JBP] 1 0 9 137 SSR - Strict Source Route [RFC791,JBP] 0 0 10 10 ZSU - Experimental Measurement [ZSu] 0 0 11 11 MTUP - MTU Probe [RFC1191] 0 0 12 12 MTUR - MTU Reply [RFC1191] 1 2 13 205 FINN - Experimental Flow Control [Finn] 1 0 14 142 VISA - Expermental Access Control [Estrin] 0 0 15 15 ENCODE - ???

IP TOS PARAMETERS This documents the default Type-of-Service values that are currently recommended for the most important Internet protocols.
TOS Value Description Reference --------- -------------------------- --------- 0000 Default [RFC1349] 0001 Minimize Monetary Cost [RFC1349] 0010 Maximize Reliability [RFC1349] 0100 Maximize Throughput [RFC1349] 1000 Minimize Delay [RFC1349] 1111 Maximize Security [RFC1455] The TOS value is used to indicate "better". Only one TOS value or property can be requested in any one IP datagram. Generally, protocols which are involved in direct interaction with a human should select low delay, while data transfers which may involve large blocks of data are need high throughput. Finally, high reliability is most important for datagram-based Internet management functions. Application protocols not included in these tables should be able to make appropriate choice of low delay (8 decimal, 1000 binary) or high throughput (4 decimal, 0100 binary). The following are recommended values for TOS: ----- Type-of-Service Value ----- Protocol TOS Value TELNET (1) 1000 (minimize delay) FTP Control 1000 (minimize delay) Data (2) 0100 (maximize throughput) TFTP 1000 (minimize delay) SMTP (3) Command phase 1000 (minimize delay) DATA phase 0100 (maximize throughput) Domain Name Service UDP Query 1000 (minimize delay) TCP Query 0000 Zone Transfer 0100 (maximize throughput) NNTP 0001 (minimize monetary cost) ICMP
Errors 0000 Requests 0000 (4) Responses <same as request> (4) Any IGP 0010 (maximize reliability) EGP 0000 SNMP 0010 (maximize reliability) BOOTP 0000 Notes: (1) Includes all interactive user protocols (e.g., rlogin). (2) Includes all bulk data transfer protocols (e.g., rcp). (3) If the implementation does not support changing the TOS during the lifetime of the connection, then the recommended TOS on opening the connection is the default TOS (0000). (4) Although ICMP request messages are normally sent with the default TOS, there are sometimes good reasons why they would be sent with some other TOS value. An ICMP response always uses the same TOS value as was used in the corresponding ICMP request message. An application may (at the request of the user) substitute 0001 (minimize monetary cost) for any of the above values.
