Search help

  • Simple searches use one or more words. Separate the words with spaces (cat dog) to search cat,dog or both. Separate the words with plus signs (cat +dog) to search for items that may contain cat but must contain dog.
  • You can further refine your search on the search results page, where you can search by keywords, author, topic. These can be combined with each other. Examples
    • cat dog --matches anything with cat,dog or both
    • cat +dog --searches for cat +dog where dog is a mandatory term
    • cat -dog -- searches for cat excluding any result containing dog
    • [cats] —will restrict your search to results with topic named "cats"
    • [cats] [dogs] —will restrict your search to results with both topics, "cats", and "dogs"

PC to iMac - Remote Build Fails : Failed to run init commands on Output = Permission denied (publickey,password,keyboard-interactive).


I have been trying to remote build from my PC to my iMac for a couple of weeks now, but have hit a brick wall.

I have followed the guides on answer hub and various posts, and seem to have things configured to the book. I have the certificate and mobile provisions setup correctly and working, rsync is setup, so is Deltacopy, unreal remote build settings and ssh key seems to be working ok, I have setup unreal on the mac and pc from source and have double checked permissions etc... Both the PC and Mac can see each other on the network.

However when I try and package my project for ios, it goes the best part of the way through things successfully until it gets to this part in the log when it complains about permissions. I don't know what is happening here, and would really appreciate some help in getting to the bottom of this, so if anyone has come across this error before then please put me out of my misery :-) :

I managed to resolve this issue.

What I needed to do was navigate to the RemoteToolChainPrivate.key file in windows explorer > right click > properties> security (tab) > edit (button) > Add the 'Users' group and assign 'Full Control'.

IMPORTANT - Remove all other users and groups assigned to this file, leaving only the 'Users' group with full control.

What type of users? Just the administrators? What did you define for object names?

Thanks so much for this tip. This did the trick for me, I was stuck for a bit, but once I removed all other groups except "Users" it worked like a charm.

alt text No luck for me on Win10. I removed inheritance so all groups removed bar Users but still getting same error as per screenshot

Ah success! An additional step was required. After changing properties as above, the Project Settings | Found Existing SSH permissions file went blank

(previously autofound key in UnrealBuildTool\SSHKeys\)

Assigned (same) key in the Override existing SSH Permissions file field below and voila, connection made.

To reiterate, you need to open the file's security tab, and delete ALL the users/names/admins listed there. Then Manually add the user group by clicking Advanced->Add->Select a Principle and manually type in 'USERS' here: alt text

Tried setting permissions as suggested and still got the same error.

What eventually worked for me was moving the RemoteToolChainPrivate.key file to a different directory, and then manually choosing it under "Override existing SSH permissions file" in the Project Settings.

In my case I just copied it to the DeltaCopy dir.
