You should have a related file to /etc/services that must have the same services setup in a file called /etc/inetd.conf.
Yours may be different but look for a file with the same service names in it.
These services are turned off in my system in /etc/inetd.conf.
time stream tcp nowait root internal
#time dgram udp nowait root internal
#echo stream tcp nowait root internal
#echo dgram udp nowait root internal
#chargen stream tcp nowait root internal
#chargen dgram udp nowait root internal
daytime stream tcp nowait root internal
daytime dgram udp nowait root internal
discard stream tcp nowait root internal
discard dgram udp nowait root internal
The /etc/services controls the port number that is used and the protocol of the port either tcp or udp.
The /etc/inetd.conf file controls the executable portion of the service by actually executing the service like telnet and ftp.
Regarding the .profile there is a default in /etc/profile and in /etc/skel directory if you have that dir.
