You can use either a demo version (which, based on our experience, has an insufficient set of features), or a full license (by paying £200 for each year). All the reports that are generated by analyzing the event log can be presented in the form of diagrams and graphs, clearly demonstrating the vulnerable aspects of the LAN. You can also obtain information about the technical specifications of all equipment currently connected to the network. Thanks to its well-designed user interface, this software provides sysadmins with a ton of configuration options, from IP ranges for auto-discovery to SNMP protocol settings needed to start collecting network information. This solution integrates with hardware from Cisco, Windows, Linux, HP, Juniper, Dell, FreeBSD, Brocade, Netscaler, NetApp, and other vendors. Observium is an application that operates using the SNMP protocol and allows not only to examine the state of a network of any scale in real time, but also to analyze its performance. If you have a small network, then you won’t even need to buy a license: the program will work in free mode. All network activity will be monitored in the activity log and special reports. Each chain element can be edited at any time and will immediately apply to all devices assigned to the scenario. You can use it to organize monitoring schemes of virtually any complexity in order to accurately identify problems and malfunctions, as well as automate the process of eliminating them.Ī scenario is a kind of a workflow based on a sensor, and from it you can construct logic chains, which will, depending on the success of a check, generate different notifications and actions aimed at addressing the problems. The main feature here is the scenario builder, which allows to escape from configuring just primitive checks, that don’t take certain circumstances of device operation into account. I allowed the router to send UDP packets to 224.0.0.251 / port 5353.Network Olympus operates as a service and has a web-based interface, which makes for greater flexibility and convenience. I allowed the router to listen to its interfaces on UDP port 5353. In the firewall, I even allowed both zones to fully communicate in both direction. but HP Smart and Naps2 still didn't see the scanner. With Avahi the HTTP printer interface was accessible using an address like m425dn.local. I tried Avahi and mDNS without any success. That's probably due to the fact there're located in different subnets. my prefered solution : scanning with the naps2 open-source application which is compatible with both WIA and TWAIN.īoth HP Smart and Naps2 don't "see" my printer/scanner.scanning with the HP Smart application,.However, I do have a problem for scanning from that device. I opened the ports to the printer on the Openwrt router and in Windows I defined the printer by entering its IP address. The computers, located in their own zones / subnets, can print. It's an HP Laserjet M425dn, which can print and scan and is connected to my network using an ethernet cable. I was ready to install the devices but I realized there's a problem with my network multifunction printer. Some weeks ago I configured my home network and installed Openwrt on a router and several managed switches.
