![]() ![]() ![]() $ sudo chmod a+rw /dev/vmnet*Īfter changing access permission, you need to restart VMware Workstation or Player to make the change effective. To allow all users (instead of a specific user) to set the virtual adapter to promiscuous mode, run the following command on host machine. Update the group ownership and access permission of /dev/vmnet* $ sudo chgrp promiscuous /dev/vmnet* ![]() To give a specific Linux user access permission to use promiscuous mode, do the following on host machine.įirst, create a new Linux group which has permission to use promiscuous mode, and add yourself to the group. Change Permission on /dev/vmnet* Temporarily Method One You need to give yourself (i.e., your Linux user ID) permission to access /dev/vmnet* in order to be able to use promiscuous mode in guest VMs. Therefore, if you are running VMware software as a non-root regular user under this setting, virtual Ethernet adapters of guest VMs cannot enter promiscuous mode. The reason for promiscuous mode not working is that VMware Workstation or Player does not allow the virtual Ethernet adapter of a guest VM to go into promiscuous mode unless VMware software has read-write access permission on /dev/vmnet* on host machine.īy default, the permission settings on /dev/vmnet* are as following, where only the root has read-write access to /dev/vmnet* $ ls -al /dev/vmnet*Ĭrw- 1 root root 119, 0 May 22 09:06 /dev/vmnet0Ĭrw- 1 root root 119, 1 May 22 09:06 /dev/vmnet1Ĭrw- 1 root root 119, 8 May 22 09:06 /dev/vmnet8 #HOW TO ENABLE PROMISCUOUS MODE WIRESHARK HOW TO#In this post, I will describe how to enable promiscuous mode on virtual Ethernet adapters created by VMware. In VMs created by VMware Workstation or Player, however, you may encounter a situation where promiscuous mode does not work on virtual Ethernet interfaces. In Linux, you can easily enable promiscuous mode by using ifconfig command. When an Ethernet adapter is turned into promiscuous mode, all packets on the connected network are received by the interface. How to use virtual Ethernet adapters in promiscuous mode on VMware ![]()
