Objective
Describe the procedures for the SSH access set up, considering that the maintenance and upcoming upgrades of OpMon versions after installation will occur by remote access, using the SSH protocol.
Target audience
Intended for administrators of OpMon and IT teams that need to perform the recommended SSH settings by OpServices.
Configuring
The OpServices RECOMMENDS that this access is configured in a DIFFERENT platform of the default port. To proceed with the set up for the SSH server to run in other port, for example, the 54978 port instead of the default 22 port, follow the instructions below:
a) Edit the file /etc/ssh/sshd_config
[root@opmon /]# vim /etc/ssh/sshd_config
b) Look for the Port entries and PermitRootLogin and leave as shown in the example below.
Port 54978 PermitRootLogin no
If you want more than one port responding to SSH, simply duplicate the line with the desired ports.
The entry PermitRootLogin is responsible for allowing the user to root login in the console, if you don’t want that to happen, you can force other user to login for becoming root later (recommended)
c) Once done this procedure, save the file.
d) Restart the sshd service as follows:
root@opmon /]# service sshd restart Stopping sshd: [ OK ] Starting sshd: [ OK ]
