[net.unix-wizards] Ultrix Network Services

hagan%UPenn-DCCS%upenn.csnet@CSNET-RELAY.ARPA (11/07/85)

I have DEC's Ultrix which is (for the most part) just bsd4.2 Unix.  However,
my /etc/services reads as following:

#
# Network services, Internet style
#
echo		7/udp
discard		9/udp		sink null
systat		11/tcp
daytime		13/tcp
netstat		15/tcp
ftp		21/tcp
telnet		23/tcp
smtp		25/tcp		mail
time		37/tcp		timserver
name		42/tcp		nameserver
whois		43/tcp		nicname
mtp		57/tcp				# deprecated
hostnames	101/tcp		hostname	# usually from sri-nic
#
# Host specific functions
#
tftp		69/udp
rje		77/tcp
finger		79/tcp
link		87/tcp		ttylink
supdup		95/tcp
ingreslock	1524/tcp
#
# UNIX specific services
#
exec		512/tcp
login		513/tcp
shell		514/tcp		cmd		# no passwords used
printer		515/tcp		spooler		# experimental
efs		520/tcp				# for LucasFilm
courier		530/tcp		rpc		# experimental
biff		512/udp		comsat
who		513/udp		whod
syslog		514/udp
talk		517/udp
route		520/udp		router routed	# 521 also
new-rwho	550/udp		new-who		# experimental
rmonitor	560/udp		rmonitord	# experimental
monitor		561/udp				# experimental

Althought I have some of these services in the form of startable background
daemons, I cannot seem to find any information on most of the "Network
Services, Internet Style".  For example: I have SMTP and FTP, but lack:

echo, discard (both upd)
systat, daytime, netstat, time, name, whois, mtp, hostnames
rje, finger, link, supdup, and ingreslock.

Do you know where I can find most or all of these?  Or could you tell me who
to contact?

Thanks in advance,

--Kid.

P.S.  I am not a supscriber to Unix-WIZARDS, so please respond directly to
      me: Hagan@UPenn.CSNET

Don't worry about it, most of the entries are informative so you
don't accidently use one of those service ports for your own applications
and (for example) find someone else's machine bothering you and getting
confused, also if you eventually install the service you will need
that port free and the entry in place. Consider it a harmless convenience.
For example, we run our own finger software here (and time) at the
specified port numbers, so they do exist at some sites. Some will
probably never exist, but one has to really understand the issues
to re-use them.

Think of them like reserved vectors in a unibus address space for
devices you don't own.

     However, a certain amount of suspicion about servers that run as root
is always a good idea.
