Remote Desktop in Centos

I am trying to connect from Centos server to another Centos Server using RDP, VNC,SSH but it does not seem to work as expected.
I can ping from /to both servers

RDP :

VNC:

SSH:

Any help ?

Thanks

Try disabling the firewall on the destination CentOS server (for testing). Can you connect now? If so you need to change firewall settings on the destination CentOS server.

Steven Vona

One the destination CentOS machine type the following command to flush iptables:

iptables -F

Then try it again.

I have run this command but did not help.
iptables -F

I posted the Firewall Gui page, it does not look like ssh is blocked.

@Gerwin Jansen, I agree, I just thought it would be helpful to explain how to do it and why iptables wasn't working.

[root@localhost liveuser]# systemctl stop firewalld
[root@localhost liveuser]# ssh root@192.168.80.139
ssh: connect to host 192.168.80.139 port 22: Connection refused
[root@localhost liveuser]#

AS you can see , I stopped Firewall but still cannot remote using ssh

Steven Vona

You need to stop it on the machine you are trying to connect to (192.168.80.139).

To explain what I have done:
I ran the below command in server1
[root@localhost liveuser]# systemctl stop firewalld

I went to server2 and ran:
ssh root@192.168.80.139

I got the following message:
ssh: connect to host 192.168.80.139 port 22: Connection refused

Steven Vona

Is sshd started on server1?

Post the output of the following command on server:

systemctl status sshd.service

jskfan

ASKER

I wonder if it is not installed

[root@localhost /]# systemctl status sshd.service
sshd.service - OpenSSH server daemon
Loaded: loaded (/usr/lib/systemd/system/sshd.service; disabled)
Active: inactive (dead)

[root@localhost /]#
