arch is x64. Versions: Tor 0.4.2.6 running on Linux with Libevent 2.1.8-stable, OpenSSL 1.1.1d, Zlib 1.2.11, Liblzma 5.2.4, and Libzstd 1.3.8. I'm testing Interactive Brokers' TWS software on Tails OS (just for fun, I see it's not a use case, however, I hope this can help), but I've met a problem launching it: 1583671114 WARNING torsocks[25196]: [syscall] Unsupported syscall number 229. Denying the call (in tsocks_syscall() at syscall.c:605) 1583671115 ERROR torsocks[25196]: Unable to resolve. Status reply: 4 (in socks5_recv_resolve_reply() at socks5.c:677) The application show an error message: Update Failed. Check log file for details: /home/amnesia/Jts/.intall4j/updater.log (see below). ---- Steps to reproduce: 1. Launch Tails 4.3. 2. Download tws-latest-linux-x64.sh or tws-stable-linux-x64.sh from [the official website](https://www.interactivebrokers.com/en/index.php?f=14099#tws-software). 3. Run the installer: for example, ``` ./tws-stable-linux-x64.sh ``` 4. After the installation, launch the application: from the installer or from Terminal: ``` torify "/home/amnesia/Jts/tws" -J-DjtsConfigDir="/home/amnesia/Jts" %U ``` or ``` . torsocks on "/home/amnesia/Jts/tws" -J-DjtsConfigDir="/home/amnesia/Jts" %U ``` 5. You get: ``` 1583672301 WARNING torsocks[26808]: [syscall] Unsupported syscall number 229. Denying the call (in tsocks_syscall() at syscall.c:605) 1583672301 ERROR torsocks[26808]: Unable to resolve.
