I just happened to be searching for a new linux surv. software when I found this one today. I downloaded the latest release version(2016-4-8). I ran it with the -core flag.
I then downloaded the Mac OS X Client. I pointed it to the port and specified password (provided by -showpassword). The client gives me the error:
Make sure that server part of Seoma is working on PC with IP address ...:8090
I also tried with the iPhone client. It gives the "No Connection" error.
I tried running the app with a normal user and in "Sudo" mode. Both had the same results.
