Restricting TFTPD Access to a Speciﬁed Directory

To restrict TFTPD ﬁle access to a speciﬁc directory, insert the appropriate line for

your operating system in the /etc/inetd.conf ﬁle.

The examples in Table 2-4 restrict access to the /tftpboot directory. You can

substitute any directory you want.

Creating Links

You must create a symbolic link for every pathname you specify in the bootptab

file. For example, to set up the symbolic links for the /tftpboot path, use the

following procedure:

1. Log in to your UNIX workstation as

root

Table 2-3. Providing TFTPD Access to Root and All Subdirectories

Operating System Sample Line to Insert in /etc/inetd.conf Directory

SunOS tftp dgram udp wait root /usr/etc/in.tftpd in.tftpd -s /

Solaris tftp dgram udp wait root /usr/sbin/in.tftpd in.tftpd -s /

HP-UX tftp dgram udp wait root /etc/tftp tftp

AIX Use the System Management Interface Tool (SMIT) to conﬁgure TFTP. For

instructions, refer to the IBM guides on TCP/IP daemons and the TFTP protocol.

Operating System Sample Line to Insert in /etc/inetd.conf Directory

SunOS tftp dgram udp wait root /usr/etc/in.tftpd in.tftpd -s /tftpboot

Solaris tftp dgram udp wait root /usr/sbin/in.tftpd in.tftpd -s /tftpboot

HP-UX tftp dgram udp wait root /etc/tftp tftp -s /tftpboot
