Question

Connection Timed Out: SSH with Custom Image (CentOS 6.5)

Posted February 15, 2021 44 views
CentOS

I was following through a tutorial in setting up firewall rules in this article: (https://www.vultr.com/docs/setup-iptables-firewall-on-centos-6)
I also did copy ssh keys into DigitalOcean security.

SSH services are ok and running but we cannot connect to it via putty nor ssh command. Can anyone help?

Hi @jgabadilla,

Most probably you denied access to port 22. What I would recommend is to allow connections to port 22 only for your IP address rather than the whole world.

To do so, use the DigitalOcean WebConsole and type in the following command once you are inside:

iptables -A INPUT -s XXX.XXX.XXX.XXX -p tcp --dport 22 -j ACCEPT

Please note you’ll need to change XXX.XXX.XXX.XXX with your actual IP adress from which you are connecting to your droplet.

Regards,
KFSys
