To create IFF private and public key file of ntp client system, first, user should enter the folder
(e.g. /etc/ntp/) where ntp keys are needed to be generated using cd command and delete all old
ntp autokey files to avoid conflict and confusion with new keys.
Then, give below command to generate ntp client IFF keys.
ntp-keygen
–H –p cryptopasswd
Where, cryptopasswd is the password used to generate the ntp clients keys and same password
should be entered in client ntp.conf file as explained in next step.
After Group Key IFF file is transferred from MTS200 trusted server to NTP clients, user need to
copy this IFF parameter key in ntp clients keys folder (as mentioned in ntp.conf file) and make
links to the transferred group key in ntp client keys folder as follows:
User should now use IFF group key of Trusted Server MTS200 and transfers it to NTP client PC
using either webserver method OR SSH method as described below:
TO TRANSFER GROUP KEY (ntpkey_iffkey_MTS200) USING WEBSERVER:
Open MTS200 webserver and go to “Security Page” and download “
NTP Autokey IFF Group Key”
downloads section in local drive. Now copy this group key in folder where previous keys were
generated. i.e. /etc/ntp folder.
Now, at NTP client side, user should enter in folder where ntp client autokey files are generated.
cd /etc/ntp
and then,
ln
–s /path*/ntpkey_iffkey_MTS200 ntpkey_IFFkey_username*
here, username = is the username of the ntp client unix or linux system
path* = is the path of folder where MTS200 trusted server IFF key is present
e.g.
ln
–s /etc/ntp/ntpkey_iffkey_MTS200 ntpkey_IFFkey_ubuntu
TO TRANSFER GROUP KEY (ntpkey_iffkey_MTS200) USING SSH:
On Remote Host PC:
ssh
Where
,
root = is the default super-user of MTS200,
192.168.100.153 = is the IP address of MTS200 ethernet port
If operator has successfully taken the console session of MTS200, then user can give below
commands to transfer the ntp keys to remote Host PC.
scp /home/root/ntp/ntpkey_iffkey_MTS200
Where
,
user = is the username of remote Host PC where keys are to be transferred,
192.168.100.231 = IP address of remote Host PC where keys are to be transferred
/etc/ntp = it is the destination folder where ntp keys are copied. This can be different
as per remote Host PC ntp client setup
