This post have the exact same title of an old one, but unfortunately the previous solution does not work for me. Have installed CentOS minimum installation in a Parallels VM, running Parallels 11.1.2 and MAC OSX 10.11.3. However, I cannot connect to the Parallels VM from OSX. I have installed Oracle XE database on the CentOS instance and would like to be able to connect to that. I have even tried to create a small python program that create a simple TCP listener, trying to narrow the search for a solution. The situation is that I could connect to oracle or to my simple program using telnet locally (on CentOS) but not from my MAC terminal. Note that by "locally" I mean a ssh session, which indicate that my Linux VM is reachable from my MAC OS network. I had already tried: Disable MAC firewall at all; Configure my VM as "Shared Network" and as "Host-only network"; The result is always the same: ssh works smoothly and oracle or my simple listener does not. I would appreciate any help or ideas to try.
I don't think so, although I could be missing something. [sergio@CentOS ~]$ sudo service iptables stop Redirecting to /bin/systemctl stop iptables.service Failed to stop iptables.service: Unit iptables.service not loaded.
If you are using centos 7, then it could be firewalld: # systemctl stop firewalld I'm not a linux guy, but could it be that selinux blocks the socket? Try to disable selinux also: # echo 0 > /selinux/enforce
