If you are running a FreeBSD or OpenBSD virtual machine (VM) in the KVM (Kernel-based Virtual Machine) hypervisor and are unable to establish FTP connections from the VM, there are a few things you can try to troubleshoot the issue:
Check the network configuration of the VM: Make sure that the VM is properly configured with a network interface and that it has the correct IP address and network settings.
Check the firewall rules: Verify that the PF firewall on the VM is not blocking the FTP connections. You can use the pfctl command to view and modify the firewall rules.
Check the host firewall: If you are running a firewall on the host system (the system where KVM is running), make sure that it is not blocking the FTP traffic.
Check the network connectivity: Make sure that the VM has network connectivity and that it can communicate with other systems on the network. You can use the ping command to test connectivity.
Check the FTP server configuration: Make sure that the FTP server is configured to listen on the correct IP address and port number, and that it is running properly.
Check for network issues: If none of the above steps help, there may be an issue with the network itself. You can try using other network tools, such as traceroute, to identify any issues or bottlenecks in the network.
