All the previous and above plus. Check /etc/xinetd.d/tftp, /etc/hosts.allow, /etc/hosts.deny Then check the ipfilter and security setting. TFTP is at a different port than FTP. If you are using the GUI Security Level Configuration tool you will have to enable TFTP under "Other ports". If ip filtering is blocking packets into the server 'verbose' flags will have nothing to be verbose about. The quick test is to disable filtering and test. ftp 21/tcp ftp 21/udp fsp fspd tftp 69/tcp tftp 69/udp sftp 115/tcp sftp 115/udp Both ftp and tftp get used by bad boys out on the Internet so watch the ownership, permissions, settings and logs. Most system admins will want to restrict TFTP access to your local hosts/networks. For the network programmers interested in historic bugs out there give this a quick read. http://en.wikipedia.org/wiki/Sorcerer's_Apprentice_Syndrome Later, mitch -- T o m M i t c h e l l Found me a new place to hang my hat :-) Now it got bought. _______________________________________________ Beowulf mailing list, Beowulf@beowulf.org To change your subscription (digest mode or unsubscribe) visit http://www.beowulf.org/mailman/listinfo/beowulf
