Hi, I am using cent os as my TFTP server. I have created a file in /etc/xinetd.d/tftp6.The content of the file is follows.
service tftp
{
socket_type = dgram
protocol = udp
wait = yes
user = root
server = /usr/local/v6/sbin/in.tftpd
server_args = /tftpboot
disable = yes
per_source = 11
cps = 100 2
flags = IPv6
bind = 3456::12:34:45
}
When I start the TFTP service(service xinetd restart),I am able to download
file with default block size -512 bytes. But in my first TFTP packet (Read Request) I am sending blksize size as 1448 bytes. So I am expecting a option ACK from server and from next data packet the blocksize can be 1448.But from server no Option ACK I'm receiving(in TFTP IPv4 I am getting Option ACK) and the first packet from
server is a DATA packet(with 512 bytes of data). So can any one suggest me
how I can enable blksize negotiation in server side for TFTP ipv6.
