Additional testing for ntpq authentication to ensure MD5 still works for
ntpq in archive
NOTE: The shown testing is ntpq(with patch) + openssl from archive. To ensure
all still works.
Testing with ntpq + fips-openssl was also done successfully.
VM-A (ntp server)
1. Edit /etc/ntp.keys to include,
1 SHA1 austintexas
2 MD5 cedarpark
2. Edit /etc/ntp.conf to include.
keys /etc/ntp.keys
trustedkey 2
controlkey 2
requestkey 2
3. restart ntp
sudo service ntp restart
VM-B (ntp client)
$ dpkg -l | grep ntp
ii ntp 1:4.2.8p10+dfsg-5ubuntu7.1+ppa1
amd64 Network Time Protocol daemon and utility programs
1. Edit /etc/ntp.keys to include,
1 SHA1 austintexas
2 MD5 cedarpark
2. Edit /etc/ntp.conf to include,
keys /etc/ntp.keys
server <VM-B ipaddress> key 2
trustedkey 2
controlkey 2
requestkey 2
3. I commented out all the "pool" entries in /etc/ntp.conf
4. restart ntp
sudo service ntp restart
On the client,
$ ntpq -c as
ind assid status conf reach auth condition last_event cnt
===========================================================
1 46728 f014 yes yes ok reject reachable 1
Notice that "auth" is ok.
$ ntpq

Note: issuing "ifstats" requires authentication.
I also tested with SHA1 and it worked as well.
And last test on client,
ntpq -p
