1) In adition to other recommendations - if You use libwrap files
/etc/hosts.{allow,deny} , have You something as
in.tftpd: 192.168.202.
in /etc/hosts.allow (192.168.202.* is client network) at server side?
2) what say logs at server side (/var/log/messages)?
3) tftp connection between F14 and F15 works fine for me, no matter
which distro is client and which server (just verified). But I was
gathered with some weird TFTP clients (mainly PXE), for which was
needed some adjustment at Fedora TFTP server. Namely:
- set "/proc/sys/net/ipv4/ip_no_pmtu_disc" to 1 (e.g. with
net.ipv4.ip_no_pmtu_disc = 1
line in "/etc/sysctl.conf" or quickly with
echo 1 >/proc/sys/net/ipv4/ip_no_pmtu_disc
)
- disable some tftp extension - in "/etc/xinetd.d/tftp" supply "-r blksize":
# server_args = -s /var/lib/tftpboot
server_args = -s /var/lib/tftpboot -r blksize
4) wireshark is very good sort of things for debugging.
