Is the Diffie Hellman algorithm safe?
The sharing of the secret key is safe. The algorithm can not be sued for any asymmetric key exchange. Similarly, it can not be used for signing digital signatures. Since it doesn't authenticate any party in the transmission, the Diffie Hellman key exchange is susceptible to a man-in-the-middle attack.
What is Diffie-Hellman key agreement?
This key Agreement can be in the form of Diffie-Hellman. Secure Remote Password Protocol is a good example that is based on this technique. Forward Secrecy: Forward secrecy-based protocols can generate new key pairs for each new session, and they can automatically discard them when the session is finished.
How to disable non-elliptic-curve Diffie-Hellman?
If you want to continue to support non-elliptic-curve Diffie-Hellman, at the very least, you should disable Group 1 support, by removing the diffie-hellman-group1-sha1 Key Exchange. It is fine to leave diffie-hellman-group14-sha1, which uses a 2048-bit prime. It is also an option to generate new Diffie-Hellman groups:

What is the Diffie-Hellman key exchange method?
Traditionally, secure encrypted communication between two parties required that they first exchange keys by some secure physical channel, such as paper key lists transported by a trusted courier. The Diffie–Hellman key exchange method allows two parties that have no prior knowledge of each other to jointly establish…
What is ephemeral Diffie Hellman (EDH)?
Because Diffie-Hellman always uses new random values for each session, (therefore generating new keys for each session) it is called Ephemeral Diffie Hellman (EDH or DHE). Many cipher suites use this to achieve perfect forward secrecy.
