Nagios Support Forum

Thanks for the feedback, issue solved.

Thanks for the feedback I will proceed as recommended.

I use NagiosXI OVA CentOS release 6.7 (Final) and I would like to know if there is a procedure to upgrade CentOS version of this OVA without deploying a new server.

Thanks.

Hi jbrunkow,

this is the OVA I use, in fact I think you missed some commands, because I would like to know exactly what the modifications I need to do in sshd_config and ssh_config in order to use only strong ciphers and avoid the MD5 and CBC configured.

Thanks.

Currently the ssh sessions are being established using weak configurations such as hmac-md5 and CBC ciphers. How can I improve security by disabling this setting on the box and force the use of more secure ciphers such as AES and 3DES? I use the standard Nagios XI OVA based on VMware.
