Hi all need your help here to fix my putty connection issue.

am using windows 10 as host machine and installed vmware work station and inside vm i have installed linux oracle server.

i have provided ip's as VMnet1 : 192.168.1.5 ,255.255.255.0
VMnet8 : 192.168.1.6, 255.255.255.0
linux server ip is : 192.168.1.101

here when i try to ping all the 3 ip's from command prompt in windows 10 machine am getting reply.
but when i try to connect the vm from putty with 192.168.1.101 and port 20 am getting the error as mentioned in subject.

Please suggest me on this issue and let me know if incase need any details if am not clear with this.

The default port for ssh is 22, not 20

ya sorry it was 22 typo error. please suggest

What type of networking in the VM, NAT, bridged, should be bridged.

yeah it in bridged

Is the sshd running in the VM? Do you know how to check that?

VMware default network is:

VMnet0 = bridged
VMnet1 = Host-only
VMnet8 = NAT

If you need two networks they should not be on the same subnet.

Are you actually entering in the PuTTy hostname box 192.168.1.101? You should be using 192.168.1.5

yes for sshd i have run the service in terminal as : service sshd restart
stopping sshd: ok
starting sshd: ok

Am trying with 192.168.1.101 from putty.

In PuTTy's hostname box you need to use the IP address of the linux server ( 192.168.1.5 ) instead of the IP address of Windows.

Thanks to all who tried to sort out the issue and help me. I have fixed my issue and will share the steps soon.
