There are several tftp extension that NetBSD folk integrated to their tftpd/tftp recently. IIRC they were 2347 TFTP Option Extension. G. Malkin, A. Harkin. May 1998. (Format: 2348 TFTP Blocksize Option. G. Malkin, A. Harkin. May 1998. (Format: 2349 TFTP Timeout Interval and Transfer Size Options. G. Malkin, A. I know nothing about auth extension yet but the protocol is quite simple (trivial :-)) and if you get a dump of udp session between the router and windows tftp client it would be easy incorporate this one. -- Maxim Konovalov, [EMAIL PROTECTED], [EMAIL PROTECTED] _______________________________________________ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-current To unsubscribe, send any mail to "[EMAIL PROTECTED]"
