In redhat7.2, using pxe to netboot a diskless workstation, with dhcpd setup and tftp(enable, server_arg= -s /tftpboot), I put vmlinux made from using mknbi-linux to compile bzImage under /tftpboot. no firewalls, in /etc/hosts.allow write in: in.tftpd: 192.168.0. but after diskless workstation get ip of 192.168.0.5; it appeared "tftp." for a very short while, then went to no response. In server, I take "tail -f" and saw that: "server in.tftpd[2397]:tftp:client does not accept options". So then I edited tftp to change server_arg= /tftpboot(erase -s) then the client appeared: PXE-T02: Access violation PXE-E3C: TFTP Error - Access Violation So how to deal with it? --http://www.eyou.com --Îȶ¨¿É¿¿µÄÃâ·Ñµç×ÓÐÅÏä ÓïÒôÓʼþ Òƶ¯ÊéÇ© ÈÕÀú·þÎñ ÍøÂç´æ´¢...ÒÚÓÊδ¾¡
