Rsync error while generating SSH key for IOS remote build

I am trying to generate my SSH key for IOS remote building without much luck. I have OSX Yosemite in a virtual machine(VirtualBox 4.3.20). I installed DeltaCopy on my window’s host and I am able to SSH in manually. When I generate my keys using the “Generate SSH Key” button in project settings. I am using engine 4.8.2, the stable release on github, built from source.

the error(s) I am getting is on the last step:
0 [main] ssh 15292 fhandler_base::dup: dup(some disk file) failed, handle 194, Win32 error 50
dup() in/out/err failed
rsync: connection unexpectedly closed (0 bytes received so far) [receiver]
rsync error: unexplained error (code 255) at /home/lapo/packaging/rsync-3.0.4-1/ src/rsync-3.0.4/io.c(632) [receiver=3.0.4]

the full output from the MakeAndInstallSSHKey batch is:

Any help would be appreciated

Did you set up the remote server in your project’s iOS settings to be your remote Mac? It looks like it is trying to use one of Epic’s remote Macs which won’t be available to you.


yes, it is pointing to my remote mac. I had used the name “a1011” out of desperation haha. If i set bUseRSync in DefaultEngine.ini to false, it is able to connect just fine, but UnrealRemoteTool keeps stopping while copying the files.

I have tried setting up rsync to run as a daemon with no luck(may or may not be due to my inexperience with rsync and the tedious nature of setting it up in osx) , but I do know the RemoteToolChainPrivate.key is created in the .ssh folder on the mac.

I am having a similar issue. I’m getting failures trying to creats the ssh key
