[ntp:questions] No synchronization !

i've got two machines in the system -

one being the classic server/firewall (named sammy.k106, Linux 
kernel-2.4.18 (133MHz, 16MB RAM), 2 eth adapters, ntpd-2.4.0, apache, 
smtp, pop, dhcp, dns, ntp, ftp, ssh, ..., firewall)

and another being the workstation behind the firewall (Linux 
kernel-2.6.7, ntpd-2.4.0)


server ntp.conf:

server 127.127.1.0              # local clock (LCL)
fudge  127.127.1.0 stratum 10   # LCL is unsynchronized

driftfile /etc/ntp.drift        # path for drift file
logfile   /var/log/ntp          # alternate log file

server si.pool.ntp.org
server 0.pool.ntp.org
server 1.pool.ntp.org
server 2.pool.ntp.org
server europe.pool.ntp.org

workstation ntp.conf:

server 127.127.1.0  # local clock (LCL)
fudge 127.127.1.0  stratum 10 # LCL is unsynchronized

driftfile /var/lib/ntp/drift/ntp.drift # path for drift file
logfile /var/log/ntp            # alternate log file

server sammy.k106


Now, while workstation synchronizes within e.g. 10 minutes, the server 
never does:

What is the problem here ?
