Folks,

does somebody have a short explanation on some services in /SYS/NET/SERVICES
(aka /etc/services) which are configured per default ? Especially why they are
needed ?

Background: within an audit, CyberCop detected these services on the HP3000 and
valued them as  a
"low risk".

The services CyperCop put into question are
TCP Port  Service        Description               Needed ?
7         echo
9         discard
13        daytime
19        chargen
21        ftp       File Transport Protocol        YES
23        telnet         Telnet                    NOT REALLY ...
25        smtp      Sendmail/iX               YES
37        time
80        www       Web Services (Apache/iX)  YES
987       unknown   SQL distributed access         YES

Interesting enough: CyperCop didn't detect
53        domain         Domain Name Service
67        bootps         Bootstrap Protocol Server
68        bootpc         "                  "                Client
110       pop3      POP3 email                YES
137       nmbp      Samba/iX             YES
139       smbp      Samba/iX             YES
514       shell          remote command
514       syslog         Syslog/iX            YES
