Preparing to take the RHCSA and RHCE Certification exams, I'm touching up while reading along to RHCSA/RHCE Study Guide by Michael Jang.
I have a host with three VMs using qemu. On this host, there are two virtual networks
virb0 which is 192.168.122.0/24 and virb1 which is 192.168.100.0/24
Now, 192.168.122 has two VMs in the virtual network, server1 and tester1. 192.168.100 has one VM, outsider1.
Setting up TCP_Wrappers (using /etc/hosts.allow and hosts.deny), anything I put in there seems ignored... I couldn't figure it out until I saw that last login stamp from outsider1 to server1 (server 1 had ALL:192.168.100. in /etc/hosts.deny). The last login happened from 192.168.122.1. I don't know why/how this is happening because when I do a traceroute from outsider1 to server1 I don't even go through 192.168.122.1...
Help please. I need to get this squared away before going off to take the RHCSA/RHCE exams.
