FC15 TFTP open timeout.

[Francis SOUYRI]

Hello,

I do some tests with others version of the tftp server and with tftp 
server from other distrib, with and without tcpwrappers and I have the 
same problem...

tftp server from fc14/15/16
# /usr/sbin/in.tftpd -V
tftp-hpa 0.49, with remap, with tcpwrappers

tftp server from Mandriva
# /tmp/in.tftpd -V
tftp-hpa 5.0, with remap, without tcpwrappers

Is there somebody with the same problem please ?

Best regrads.

Francis
