Once found, I checked the x-refs for this value to find the Register Function table. To do so, I popped DayZServer_圆4 open in Binary Ninja and looked for the string “OpenFile”.
#Arma 3 sync failed to retrieve file code#
I am not going to write a ton more code just to bypass this, and I am definitely not going to use a Symlink between the $profile: and $CurrentDir: directories. Just don’t let the user write to executable files.Īnyway, we need to find a way around this. Instead of checking what path the server is writing to, I would recommend they limit writing by file extension. Imagine if someone managed to write binary data! In reality, I think they handicapped their own system. I would imagine Bohemia’s goal here was to increase the security of their game. We can’t open files in the root directory with WRITE. It seems that we can only use FileMode.WRITE (and FileMode.APPEND) in the $saves: and $profile: directories.

We can’t open our ban.txt file! After a bit of debugging, I learned that we can open the ban.txt file, but only with FileMode.READ. But the end result is that, in typical Bohemia fashion, OpenFile is returning NULL. So here, we pull my bans from my API, open a handle to our ban.txt file in the root directory, and write our bans to disk. Let me show some of the code I came up with to do that: I would send a web request to my API, retrieve my ban list, and write that to the ban.txt file in the server root. I imagined this would be the perfect solution. We can read and write to disk, and we can easily send and get results from Web Requests. DayZ does have two systems that Arma does not. So we can’t directly interact with server commands. Sadly, the technology just isn’t there yet for DayZ. Another solution could be using functionality similar to Arma 3’s serverCommand. While this would be cool, it’d be impractical to maintain. So the solution infiSTAR and Fini came up with, using an extension to write to this file, won’t work for us without creating an extension system ourselves. Unlike in Arma 3, Extensions are not supported. In order to sync bans, I opted to follow the same method infiSTAR and Fini use for their Arma 3 anticheat solutions by writing directly to the ban.txt file on the server. The idea is all server bans will be aggregated into a database and synced between all of my official servers. So my recent work on DayZ BR has lead to me creating my own ban management system.
