I have had great success with the following packages. You do need to know about your network and some linux basics to get everything logged. You will need to log traffic for the ips on your network using the firewall to be able to get graphs for each of them.

Try, spiceworks it's a web based 'free' network monitoring solution, i've used it before, it's quite good for some small business scenario.

Munin is a great tool for graphing system resources including the network, it does not do all the things that you are asking for but it will get you a pretty good idea of the system load. Munin is available in FreeBSD ports both the server and client

You didn't say what distribution you're using, but on Debian derivatives (Ubuntu, etc.) you can specify scripts to be called at various points in the setup/teardown of an interface in its config stanza in /etc/network/interfaces. You can specify scripts to be called at each of these points: pre-up up post-up down pre-down post-down You can also drop ...

Ahhhh....it doesn't really work that way. As long as the first nameserver is running and active all bind requests will go to it. The only way that you get to the second nameserver is if the previous nameserver in the list has died and after a LONG timeout. To fix your problem, I'm guessing that you might have to build a local caching DNS server ...

I think you can set your "search domain" right in Network Manager. Right-click on nm-applet Select Edit Connections Click on auto eth0 and select Edit click on the ipv4 Settings tab, and fill in the search domsins line (may have to select automatic (DHCP) addresses only from the dropdown list.) Hope that helps.

I think you should be looking at iwconfig and wpa_supplicant. You should be able to use those appropriately within /etc/network/interfaces (on ubuntu or debian at least) to do said config. Some googling for 'system wide wireless network config' turns up that "Fedora 10 still provides the older system-config-network tools for easy system-wide configuration ...

Well, I don't know how to do this with NetworkManager. However, I would like to point you out to my favorite network client - Wicd. Install it, there is CentOS 6 RPM available. Then start its wicd-ncurses interface and you can set it up once and forget about it. When you are done, disable your NetworkManager service and enable the wicd one. No need to touch ...

You should have nmcli in that version nmcli con list That will list connections you have setup. Find the VPN one nmcli con up uuid <uuid>

Just disable the NetworkManager service if you're working with server systems. It is not installed on the production systems I deploy because of its ill interaction with normal services. It has no place in a server deployment mainly because it is for enabling interfaces during interactive user sessions.

I recomend trying the ManageEngine product line. There are full featured free version that cover small networks.

This works for me: http://www.softwarepassion.com/solving-dns-problems-with-openvpn-on-ubuntu-box/ The important step is adding following two lines of configuration into your client openvpn config file: up /etc/openvpn/update-resolv-conf down /etc/openvpn/update-resolv-conf It works with openvpn client service or command. However, the Ubuntu Network ...

We run Cacti on a Windows XP machine.(virtual) It works great, and we haven't had much problems with it. Screenshot of our main internet connection.

I like IPMonitor, it's cheap and you can monitor servers, switches, SMTP, any service or event and you can build dependancies so you won't get alerted by a hundred servers if it's just a switch that is down between your server with IPMonitor and the other servers.

One of the best I've used is PRTG from Paessler. It is relatively cheap for a small number of servers. They charge based on the number of things being monitored (ping, free disk, cpu load etc). It's completely web-based and no agents are required. It comes with a load of predefined WMI queries and of course you can define your own (they supply templates you ...

I'm a fan of Hyperic HQ - the agent is Java based so it runs on many different platforms. The server runs on Windows with a MySQL database.

Microsoft Network Monitor is a free download. Try http://www.microsoft.com/downloads/details.aspx?displaylang=en&FamilyID=983b941d-06cb-4658-b7f6-3088333d062f JR

You could try "The Dude" It'll auto discover all your devices and monitor them as well. http://www.mikrotik.com/thedude.php It's just the name ...

You can still use NetworkManager! Set up your wireless using NetworkManager. Then right-click the NetworkManager applet, choose "Edit Connections...", find your wireless connection under the Wireless tab, choose "Edit", and select the "Available to all users" checkbox. Once your settings have been saved, NetworkManager should bring the connection up on boot ...

One thing to be aware of, is that three years after Vista and two years after Server 2008 came out, many system admin programs, including network monitors, don't work properly under the new security environment introduced by both OS's. This is known as the "Session 0 Problem" and it afflicts Windows programs that run as a service (many, many admin ...

Darkstat is a very simple but powerful network traffic monitoring program that displays information about network traffic moving over an interface via HTTP. It will do 90% of what you need with none of the hassle of using a more feature rich but complicated solution like Naigos.

If you add the proper parameters to your dhclient.conf, they will get put into the resolv.conf when it is rewritten supersede domain-name "mydomain.com" might be what you're looking for. Check the man page or online documentation for dhclient for more details.

We ran into a conflict between NetworkManager and network service on a recent install of CentOS 6.4 64-bit. "NetInstall"ed CentOS as a server (with additional packages), which created a system with both NetworkManager and network service managing eth0 (primary network card). System had a fixed IP address obtained from central DHCP service. No apparent ...

Working on this question in Fedora 20. Have quick diagram of the files involved, as it might be useful to anyone who comes along.

The relevant configuration is in /etc/sysconfig/network/config. When NetworkManager is enabled (NETWORKMANAGER="yes"), as it seems to be in your case, the default DNS update policy NETCONFIG_DNS_POLICY="auto" translates to NETCONFIG_DNS_POLICY="STATIC_FALLBACK NetworkManager" as outlined in the netconfig(8) man page. This means the static DNS ...

OpenVPN is currently unable to push DNS settings. You will have to manually change /etc/resolv.conf to match your (secured) DNS server. I just run a BIND9 service on the same machine as my Access Server and point to that via tunnel. Use your local IP adress of that machine eg 192.168.1.110 Good luck! Jasper

Ha - I've been trying to figure this out for hours, but just realized the NetworkManager daemon is running, which apparently is blocking when the network interfaces are set to not use the NetworkManager. Simply running service NetworkManager stop And then restarting fixed everything. Hopefully this will help other people out - I saw a bunch of similar ...

I currently have a similar problem on Ubuntu 10.4 LTS. This is my home Desktop system, but I also use it with KVM & libvirt. This is some sort of conflict between regular network interfaces (eth0) and interfaces for Virtualization (Bridged interfaces like br0, VirtualBox's interface like vboxnet0). It seems that Ubuntu's Network Manager doesn't play ...
