TFTP Service

Implementation Differences

The implementation of tftpd on the HP 3000 differs from tftpd on the

HP 9000 in three ways:

• On HP-UX, tftpd is usually run as root. On MPE/iX, it is usually

run as USER.TFTP.

• On HP-UX, tftpd checks if the user tftp can write to or read the

ﬁle. On MPE, tftpd checks if the user speciﬁed in its conﬁguration

ﬁle can write to or read the ﬁle. If you conﬁgure tftpd as

recommended in this chapter, USER.TFTP will be speciﬁed in the

conﬁguration ﬁle and tftpd will check the same user.

• On MPE/iX, the tftp user is conﬁgurable and it is not on HP-UX. As

a result, on MPE/iX tftpd looks at the ﬁle relative to the home

directory of whichever user is speciﬁed in the inetd conﬁguration

ﬁle. On HP-UX, inetd always looks at the ﬁle relative to the home

directory of the tftp user.
