I'm trying to set up an ntp server, and I can't query it. Whenever I try, I get this message:

 6 Mar 18:57:01 ntpdate[27050]: no server suitable for synchronization found

Here is my ntpd.conf file

# For more information about this file, see the man pages
# ntp.conf(5), ntp_acc(5), ntp_auth(5), ntp_clock(5), ntp_misc(5), ntp_mon(5).

driftfile /var/lib/ntp/drift

# Permit time synchronization with our time source, but do not
# permit the source to query or modify the service on this system.
restrict default nomodify notrap nopeer noquery

# Permit all access over the loopback interface.  This could
# be tightened as well, but to do so would effect some of
# the administrative functions.
restrict ::1

# Hosts on local network are less restricted.
restrict mask nomodify notrap

# Use public servers from the pool.ntp.org project.
# Please consider joining the pool (http://www.pool.ntp.org/join.html).

# Disable the monitoring facility to prevent amplification attacks using ntpdc

////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////// This was my first post, so I don't know how solutions are usually posted, so I'll just put it here. So, it turns out my teacher who's server I was connecting to via ssh had a firewall up that was blocking ntp. He was using firewalld, and to solve this, I used these commands:

firewall-cmd --add-service=ntp --permanent firewall-cmd --reload

Check the status of your ntp server: systemctl status ntpd

If it's down: start the server up: service ntpd start

  • That seems a somewhat out-of-date config, but should mostly work. Include the output of ntpq -npc rv and it should show that @MichaelHampton is right and you have no Internet connectivity. – Paul Gear Mar 7 '19 at 9:48
  • Thank you for the help. I am connected on my end. I'm using putty to ssh into my teacher's server and he's in control of everything from that end. I just pinged google to ensure that he's connected, and it worked so I'm not sure what the issue is. – Nate Powe Mar 7 '19 at 16:10
