1. Note ngnms user has sudo privileges so you may do anything you like with the system after initial installation is done It is good idea to install your favorite VM tools and drivers at this time The operating system is generic Ubuntu 14 04 LTS so everything you know about it will work Please follow your hypervisor system documentation to complete these tasks Optional configuration steps Adding SNMP MIBS NG NetMS needs SNMP for automatic recognition of the devices and for processing of the incoming SNMP Alarms The MIBs could be located at NGREADY mibs directory Just download the necessary MIBs and place the unzipped files there Make sure that all required dependencies are resolved The system will start using new MIBs automatically after the manual reload of the collectors or after system restart Note in the case if Try Ubunty method was selected the downloaded MIBs will disappear after system reboot Adding SSH Add OpenSSH server with apt get utility sudo apt get install openssh server Post Install Settings for the managed environment Network IP Addressing NG NetMS supports only IPv4 addresses at this time You will need routable IPv4 network through which the devices could be reached by NG NetMS host This tool relies on ISIS or OSPF topologies for network discovery Telnet or SSH access to the network devices is mandatory Also the tool needs internet connectivity with unrestricted web access for u2. and interface DNS names and IP addresses In the case of OSPF networks the tool may work without DNS but use of DNS is recommended For ISIS networks the hostname or the router should point to its Router ID IPv4 address otherwise the NG NetMS would not be able to discover such devices Typically the Loopback 0 interface may be used for this purpose Login settings NG NetMS supports Telnet access method out of the box SSHv1 and SSHv2 are also available out of the box but require manual creation in order to be used See more on this is in User Guide Syslog redirection All managed devices should be configured to send the syslog to the remote host i e directrly routable IP address of NG NetMS Use of NAT devices and Application Level Gateways ALG firewalls between the managed network and NG NetMS is not recommended due to necessity of special firewall and NAT policies Redirection of syslog may be achieved with one of the following commands Juniper routers and switches JUNOS gt show configuration system syslog archive size 500k files 5 host 192 168 3 110 any info host L92 IGS Sho LILA i Guay ENEO source address 192 168 255 1 Cisco routers IOS logging trap informational logging source interface Loopback0 Hioxerepave ILE 2 5 IMGs 5S LIL 7 logging on SNMP settings and redirection All managed devices should be configured to send the SNMP Alarms to the remote host i e directrly routable IP

11. se of the cloud analytics and access to security patches and other resources IMPORTANT By default NG NetMS is secure enough to be placed on public internet as long as login passwords for root and ngnms accounts are changed by the user from default values Please adhere to your organization s security standards and policies Opt Net can not be held liable for any security incidents which derive from improper configuration of the user accounts and access policies We recommend to place NG NetMS behind the firewall with strict access restrictions Direct access from the Internet should be disallowed Guard it as the rest of your infrastructure NG NetMS may be used in private VPN and private Cloud network configurations but use of NAT between managed devices and the tool is not recommended In the case if there are firewalls NAT devices or application gateways in between the managed devices and NG NetMS tool the special policies will be required to permit telnet ssh and SNMP GET requests towards devices and reverse policies In particular special care should be taken to allow asynchronous and unsolicited syslog and SNMP alarms from managed network to reach NG NetMS tool Ideal placement for NG NetMS tool is on Operations and Maintenance network OAM inside of the managed network DNS Settings The managed network should have proper configuration for direct and reverse DNS resolution NG NetMS relies on proper DNS mappings between router
