How do i make factions non-hostile?

Currently every faction i know wants to murder me, How do i make them stop.

When they raid you, collect their wounded and patch them up. Then once they are on their feet again, go into the prisoner tab and select the release option. You will get a 15 relationship boost for each released prisoner who leaves the map.

Note that this only works for outlanders and tribes, pirates can't be made friendly.

You can also use the communications console and pay a faction 300 silver. This tends to improve relations by about 14, depending on Social skill.

When you capture one of their colonist, release them. You'll get 15 points towards better relationship. Only works if they are not pirates. Once they are non hostile, you can contact them and pay them for relationship points.

if you can afford this and you have high enough relations already this is probably the best option, but if you check everyone you can from your comms console most of them "hurls some epithets and hangs up" you'll have to resort to what others are talking about.

thanks for the tip by the way, i didn't realize you could repair bad relationships with others at all once they get below the donation threshold.

If you aren't adverse to using mods, try Hospitality - It lets you talk to visitors from other factions and earn a better reputation that way. 

I use it and I love it!

Can you no longer make friends with pirates? Reputation with them doesn't go up when they leave map. It works for tribals.

No, you can't make pirates friendly anymore, only tribals (and outlander towns you've made hostile).
