2. For the service that you are installing, check the ﬁle to see if it has

the appropriate entry. (Each chapter in the remainder of this

manual has this information.) If not, enter the line in the ﬁle using

the “Editing Tips” section, next, as a guideline.

NOTE For more information on FTP, refer to Installing and Managing HP

ARPA File Transfer Protocol Network Manager’s Guide or HP ARPA

File Transfer Protocol User’s Guide.

3. Save the ﬁle and exit the editor program.

Editing Tips

When you are editing the services ﬁle, use the following information to

enter the information correctly.

• If you ﬁnd the line that describes the service you are conﬁguring, but

it has been “commented out” (that is, preceded by a pound sign, #),

the service has not yet been enabled. To enable it, simply delete the

pound sign

and

any spaces that precede the service name.

• If you need to type the line into the ﬁle:

— use only lower case characters

— enter the service name in the ﬁrst column without any leading

spaces

— separate the individual ﬁelds on the line with any number of

blanks or tab characters to improve readability
