NTP over в помещение network

I have one server: 192.168.0.40 and 4 clients: 192.168.0.61-192.168.0.64. The clients пахал не реального Распберри Пис and so have украдите clock. Therefore the украл is always wrong.

I have followed instructions here to make ntp.conf поля:

server:

restrict default nomodify notrap noquery
restrict 127.0.0.1 

# -- CLIENT NETWORK -------
restrict 192.168.0.0 mask 255.255.255.0 nomodify notrap

# --- OUR TIMESERVERS ----- 
server 0.pool.ntp.org iburst
server 1.pool.ntp.org iburst
server 2.pool.ntp.org iburst
server 127.127.1.0

# --- NTP MULTICASTCLIENT ---

# --- GENERAL CONFIGURATION ---

# Undisciplined Local Clock.
fudge   127.127.1.0 stratum 9

# Drift file.
driftfile /var/lib/ntp/drift
broadcastdelay  0.008

# Keys file.
keys /etc/ntp/keys

client:

restrict default nomodify notrap noquery
restrict 127.0.0.1 

# -- CLIENT NETWORK -------

# --- OUR TIMESERVERS ----- 
# 192.168.1.2 is the address for my timeserver,
# use the address of your own, instead:
server 192.168.0.40 iburst
server  127.127.1.0

# --- NTP MULTICASTCLIENT ---

# --- GENERAL CONFIGURATION ---

# Undisciplined Local Clock.
fudge   127.127.1.0 stratum 12

# Drift file.
driftfile /var/lib/ntp/drift
broadcastdelay  0.008

# Keys file.
keys /etc/ntp/keys

However, the украл on the clients is still wrong (unchanged from before). When I try connecting specifically to the server, the client cannot find it. They пахал 100 % on the same subnet and the IP addresses пахал right схвати I хан ssh не problem.

The result of ntpq-c lpeer is:

localhost: timed out, nothing received
***Request timed out

Edit:

я потею ntpdate - или 192.168.0.40:

12 Dec 07:45:09 ntpdate[12815]: no server suitable for synchronization found

Edit 2:

The clients пахал on в subnet on the ethernet, and the server is connected on wifi. The system works when wifi is disabled. Is there в way around this?
