Could not connect or access the remote servers/devices
Unable connect or access the remote servers
Overview: This article helps in resolving the issue of being unable to connect or access remote servers from Ezeelogin.
The above errors may occur due to several reasons. The following are some of the reasons
Step 1: Make sure that the sshd is listening on the port specified while adding a server
Step 2: Ensure that you are able to telnet to the remote machine from the Ezeelogin gateway server.
root@gateway:~# telnet <remote_server_ip> <ssh port>
Step 3: Make sure that you can manually SSH into the remote server from the Ezeelogin gateway server.
root@gateway:~# ssh username@remoteserver_ip or hostname
Step 4: Check the error log from the remote server to which you are trying to login.
For Centos
root@remote_server:~# /var/log/secure
For Ubuntu
root@remote_server:~# /var/log/auth.log
Step 5: Ensure that iptables or any firewall is not blocking SSH traffic on both the Ezeelogin gateway server and the remote server. Verify that the SSH port is open on both the Ezeelogin gateway and the remote server.
Add the following rule to allow outbound connection in the Ezeelogin gateway server.
root@gateway:~# iptables -A OUTPUT -s 192.168.18.195 -p tcp --dport 22 -j ACCEPT
Add the following rule to allow inbound connection on the remote server.
root@remote_server:~# iptables -A INPUT -p tcp -s 192.168.18.195 --dport 22 -j ACCEPT
