@mihai: in afara cazului ca are ceva setari dubioase pe switchuri, nu
are nicio treaba cu dimensiunea pachetelor. pe centos exista un singur
server care functioneaza din fuleu ( eu folosesc din 2002 exclusiv
pachetul din distributie si nu am avut nicio greata cu vreuna dintre
versiuni ( la trecerile de la centos 3 la urmatoarele ))
@adrian: ruleaza un tcpdump sau wireshark pe server si o sa vezi exact
in ce se impiedica.
la mine configul serverului arata asa:
service tftp
{
disable = no
socket_type = dgram
protocol = udp
wait = yes
user = root
server = /usr/sbin/in.tftpd
server_args = -s /var/lib/tftpboot -v
per_source = 11
cps = 100 2
flags = IPv4
}
