To create an ssh key pair for NagiosQL:
=======================================
Remote system:
1. Create an user (like nagiosql_usr)
Local system
2. Create a path for the ssh keys
# mkdir /etc/nagiosql/ssh
2. Create a key pair (only rsa is supported!)
# ssh-keygen -t rsa -b 4096
Generating public/private rsa key pair.
Enter file in which to save the key (/root/.ssh/id_rsa): /etc/nagiosql/ssh/id_rsa
-> empty passphrase!
3. Copy the key on the remote system
# ssh-copy-id -i /etc/nagiosql/ssh/id_rsa/id_rsa.pub nagiosql_usr@remote-system
4. Check the permissions (read access for apache user)
# chown wwwrun /etc/nagiosql/ssh/id_rsa
5. Check the login on the remote system:
# ssh -i /etc/nagiosql/ssh/id_rsa nagiosql_usr@remote-system
-> Login without a password should be possible!
6. In NagiosQL GUI - go to Administration -> Domain and edit the domain data of your remote system:
6.1. Select SSH/SFTP as Method
6.2. Fill in nagiosql_usr as User
6.3. Fill in /etc/nagiosql/ssh/ as Directory of the key pair (without id_rsa)!
Using passwort authentication (not recommended)
===============================================
If you are using ssh2 with user/password - you have to enable PasswordAuthentication in your sshd_config:
PasswordAuthentication yes
Installing SSH2 Module for PHP
==============================
1. Install pecl extension from distribution (probably part of php5-devel)
2. Install libssh2 devel from distribution
3. # pecl install ssh2
or
# pecl install ssh2-beta
(Use predefined values -> return)
4. Add ssh2.so to your php.ini:
extension=ssh2.so
