The previous entry must be present in the conﬁguration ﬁle for Prestoserve

to operate properly.

Certain Prestoserve hardware implementations require an additional entry

in the system conﬁguration ﬁle. For information on the Prestoserve

hardware and its supporting software, see the Guide to Prestoserve.

5.6.7.4 Terminal Service

The pty conﬁguration ﬁle entry speciﬁes the number of available

pseudo-ttys (used for incoming network logins and for windows). Deﬁne

this entry according to the maximum number of ptys supported by your

conﬁguration. You can set the value to any number greater than 16 and

less than or equal to 3162. The number of logins (users) is not the same as

the number of pseudo-ttys.

There are two implementations of ptys available: STREAMS-based and

clist-based. The default is STREAMS-based and is speciﬁed with the

RPTY keyword. You set the number of psuedo-ttys in the

/etc/sysconfigtab ﬁle as follows:

pts:

nptys = 512

The default is 255.

Note that you must also have the LDTTY option deﬁned for

STREAMS-based ptys.

You deﬁne the clist-based implementation as follows:

pseudo-device pty 255

You may use either the RPTY option or the pty psuedodevice, but not both.

UNIX system mechanism for data storage, data retrieval, and data

protection.

_______________________ Note _______________________

The Logical Volume Manager was retired in Tru64 UNIX Version

4.0. To continue using enhanced disk management software, you

must migrate to the Logical Storage Manager (LSM) software.
