--00000000000091fd6a0627868760 Content-Type: text/plain; charset="UTF-8" Hello. I'm trying to connect to my mobile phone using adb over wifi using the Linuxulator because I want to install a specific java application that requires Linux to work. I have already used Linux virtualized with bhyve and it worked. But I prefer to save some memory by trying to use the Linuxulator instead of starting a vm,if possible. I've already tried to run the app using java installed natively on FreeBSD,but it fails because it wasn't designed for this. So : [root@noble /]==> adb connect 192.168.1.2:5555 * daemon not running. starting it now on port 5037 * cannot bind 'tcp:5037' ADB server didn't ACK * failed to start daemon * error: cannot connect to daemon that's the error that I get. I'm not sure if I can use some trick or if there is anything that I can do because the Linuxulator does not support that in any way. Instead,if I launch it directly in FreeBSD,it works : [root@marietto /home/marietto]==> adb connect 192.168.1.2:5555 * daemon not running; starting now at tcp:5037 * daemon started successfully connected to 192.168.1.2:5555 The problem is that the java app does not recognizes that the adb server is working : [root@noble /home/marietto/Desktop/Files/OS/Linux/Tools/DeskDockServer_1.3.0]==> java -jar DeskDockServer_1.3.0.jar Program: DeskDockServer 1.3.0 System: Linux 5.15.0, amd64 JRE: 21.0.5+11-Ubuntu-1ubuntu124.04 AdbLocator: Found ADB in env PATH class com.floriandraschbacher.deskdockserver.Main: Using ADB from /usr/bin/adb ab@3f95b479: Error getting devices: ADB server didn't ACK q$b@31524dfb: Error getting ADB devices: java.io.IOException: java.io.IOException: ADB server didn't ACK but it is working : [root@noble /home/marietto/Desktop/Files/OS/Linux/Tools/DeskDockServer_1.3.0]==> ps ax PID TTY STAT TIME COMMAND 6089 pts/0 R+ 0:00 ps ax 5979 pts/0 S 0:00 adb -P 5037 fork-server server 5952 pts/0 S 0:00 /bin/zsh According with this thread : https://forums.freebsd.org/threads/make-jail-available-to-bind-only-certain-ports.85609/ I want to create a Jail with a public IP address. But as we have an IPv4 address shortage. I want to only make the jail able to bind to a range of ports (say 700 to 750).
