Please note that tftp does not take into account any security, ownership or access restrictions when coping files from a system. Steps for success in using TFTP. 1. Decide on a very non-privileged user. ie. no root privileges 2. a. chown /etc/tftpd to that of the user. e.g. chown username /etc/tftpd b. chmod tftpd to set the setuid bit so that tftpd will run as that user e.g. chmod 4755 /etc/tftpd 3. Create a /tftp spool directory owned by same user. *NOTE* - Step 3 is a requirement for tftp puts e.g. tftp -p xxx 4. Modify /etc/inetd.conf so that the user column on the tftp line is the username selected. IMPORTANT NOTE: Please examine the syntax examples in the man pages for tftp very carefully. The examples are not straightforward and require some studying. Bob "The Renegade" Spear spear_r@apollo.hp.com "Anything worth knowing, cannot be understood" Woody Alan
