Comment 13 for bug 1884265

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

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
