Unable to SSH into brand new Centos VM

Post by skb007 » 2020/06/26 04:45:33

I have a laptop running windows 10 and I have installed VMWare WorkStation 15.
I have installed Centos7 on Vmware Workstation guest.
SELinux has been diabled.
Firewall has been tuened off.
SSHD is running.
IP address of Centos7 has been statically assigned as 192.168.1.222 Mask 255.255.255.0 and gateway as 192.168.1.1.
Centos7 is able to ping the gateway as well Vmware host machine and it is able to access internet.
IP address of Vmware Host is 192.168.1.200 Mask 255.255.255.0 Gateway 192.168.1.1.

But i am unable to ping/scp/ssh/ftp/sftp into the centos7 from the Vmware host machine.

Any help would be much appreciated.

Does it work if you use DHCP? I seem to remember that vmware blocks traffic from static ip addresses that it thinks are part of its DHCP pool. Also check your vmware network settings as it will need to be in the equivalent of what KVM calls bridged mode.

No, it does not work with DHCP. That is how it was to begin with then I decided to give it a static IP.
Network adapter is configured in "Bridged" mode for the VM. I tried to change it to NAT but that did not help either.

Vmware host does not even see the MAC (arp) address of the guest.
I have tried to run tcpdump/wireshark on Centos7 to see if there is any attempt of ssh request coming in but nothing.
There is no sign of any anomaly in /var/log/messages or /var/log/secure.

I am stumped.
