tftp-сервер

[handler]

Здравствуйте!

SuSE 11.2 tftp - все из коробки

/etc/xinetd.d/tftp

service tftp

{

socket_type = dgram

protocol = udp

wait = yes

flags = IPv6 IPv4

user = root

server = /usr/sbin/in.tftpd

server_args = -s /tftpboot/dsl

disable = no

}

/tftpboot/dsl - содержит все файлы для РХЕ-загрузки

service xinetd restart

netstat -a|grep ftp

tcp 0 0 *:ftp *:* LISTEN

tcp 0 0 *:ftp *:* LISTEN

udp 0 0 *:tftp *:*

dhcpd.conf

ddns-update-style none;

authoritative;

option domain-name-servers 192.168.0.20;

allow bootp;

allow booting;

subnet 192.168.0.0 netmask 255.255.255.0 {

option routers 192.168.0.21;

group {

next-server 192.168.0.21;

filename "pxelinux.0";

host comp01 {

hardware ethernet 00:13:d4:42:34:51;

fixed-address 192.168.0.1;

}

}

}

Далее запускаем машину с адресом 192.168.0.1.

Она получает адрес а от тфтп-сервера ответа нет

1. Может, прежде pxe имеет смысл проверить работу сервера с обычного tftp клиента?

2. Для PXE чаще используют tftpd-hpa сервер. Во всяком случае, у меня с ним проблем не было.
