Use self adhesive fiberglass mesh tape over the cracks.

If you have alot of spider web cracks, you can apply large 'webs' or large sheets of mesh over the areas.
Purchase Durabond compound mix. H.D. carries it. Get the 90 minute kind. Mix it according to directions to a plaster-like consistency. Apply it over the mesh tape as you would normal joint compound over drywall. If you have a large area to repair, then skim coat it over the mesh.
Allow it to dry, then scrape any lumps, or lines down with a trowel or 6" taping knife. Apply an additional skim coat over that.
When that coat dries, if it needs another coat - use redimix light weight compound to skim coat again. Make sure that each coat you do is 'thinner' in it's thickness, and wider than the previous coat. Last, sand it as you would normal drywall.....
If the areas are worse off, you can refer to this information:

...no problem, that is good news = less repair work to do for you...
