Hi all, Anyone using some linux software to monitor a network? I want something that prints stuff out in text on a web interfaces. at least the most stuff i would be grateful. Want to install that on a raspberry pi to see what the network devices are doing. so support for snmp and other protocols would be nice. anyone has an idea?

Hi. Been a while since I tried. Will be watching this thread. I tried NtopNG briefly. This produces stats and info you can look at in a webpage. It requires a paid for plugin to work with netflow if I recall. I need to have a look it again actually. Not sure I configured with SNMP. There's also cacti which can collect SNMP data, display graphs and stats in a web interface. There are quite a few for SNMP collection actually. Active analisys. I'm sure you know but if using sniffing, AKA traffic analysis, it's important where you place the sniffing system. My NtopNG was a VM on a virtual network between some VM hosts and a virtual upstream router. SO snaffling up all traffic that traversed the link.

Try tshark via a Linux terminal. You can filter the output to show just the protocols or addresses of interest - see the documentation for details. It is a while since I've needed it, but I have successfully used it. -----Original Message----- From: Blind-sysadmins [mailto:blind-sysadmins-bounces@lists.hodgsonfamily.org] On Behalf Of Chris Turner via Blind-sysadmins Sent: Friday, September 1, 2017 7:58 AM To: Blind sysadmins list Cc: Chris Turner Subject: Re: [Blind-sysadmins] network monitoring Hi.

Hi, Thanks for that as well. I am also on search of a network monitoring system that can check health of computers, servers and different services. anyone has a tip? thanks. Greetings, Simon Am 01.09.2017 um 21:19 schrieb Jason White via Blind-sysadmins:

I think that's a different class of network monitoring. One approach would be to write a script for it that pings hosts, attempts to connect to services, etc. -----Original Message----- From: Blind-sysadmins [mailto:blind-sysadmins-bounces@lists.hodgsonfamily.org] On Behalf Of Simon Eigeldinger via Blind-sysadmins Sent: Friday, September 1, 2017 4:06 PM To: blind-sysadmins@lists.hodgsonfamily.org Cc: Simon Eigeldinger Subject: Re: [Blind-sysadmins] network monitoring Hi, Thanks for that as well.

11:05 a.m.

I wrote a reasonably large application to do all of this but I abandoned it because It requires a minimum of Windows 2012 to get the right information out of WMI. If someone wants to take this on and expand it I'd be happy to open source it. Contact me off list and we'll discuss it. It's written using c# using .net 4.6. It uses WCF for communication between the agents on servers and desktops back to the bridge then wCF again from the bridge to the installable monitoring client that can be used on administrator PC's. Data is shown in both text and graph form. For ease of use, a key combination is built in to speak the contents of the graph and to quickly report if there's anything that needs attention. It's a brilliant project if I do say so myself but the more I tried to do with it while staying within the confines of .net and WMI, the more I needed to target newer versions of windows. It became impractical for my needs as I have machines here using everything from Windows 2003 to Windows 2016.

Hi Guys,

I use Pandora FMS which is a decent free solution. PRTG is another free one up to 100 devices if I am not mistaken.

I think that's a different class of network monitoring. One approach would be to write a script for it that pings hosts, attempts to connect to services, etc.

Try tshark via a Linux terminal. You can filter the output to show just the protocols or addresses of interest - see the documentation for details. It is a while since I've needed it, but I have successfully used it.

Hi.

Been a while since I tried. Will be watching this thread.

I tried NtopNG briefly. This produces stats and info you can look at in a webpage. It requires a paid for plugin to work with netflow if I recall. I need to have a look it again actually. Not sure I configured with SNMP.

There's also cacti which can collect SNMP data, display graphs and stats in a web interface.

There are quite a few for SNMP collection actually.

Active analisys. I'm sure you know but if using sniffing, AKA traffic analysis, it's important where you place the sniffing system. My NtopNG was a VM on a virtual network between some VM hosts and a virtual upstream router. SO snaffling up all traffic that traversed the link.

Hi all,

Anyone using some linux software to monitor a network? I want something that prints stuff out in text on a web interfaces. at least the most stuff i would be grateful.

Want to install that on a raspberry pi to see what the network devices are doing. so support for snmp and other protocols would be nice.

anyone has an idea?

Greetings, Simon

I'll have to dig it up, and I was right, if not me, my friend wants some more .NET opportunities, so I think we've got something. I suppose I'll set up a repo at: https://github.com/stormlighttech If you look there, you'll find that the rest of the group's done quite a bit of work on several projects; one of them was recently tossed out by its original authors as well. -----Original Message----- From: Blind-sysadmins [mailto:blind-sysadmins-bounces@lists.hodgsonfamily.org] On Behalf Of Darragh Ó Héiligh Sent: Thursday, September 07, 2017 6:47 AM To: Blind sysadmins list Subject: Re: [Blind-sysadmins] network monitoring Please see the first message I wrote for details of the languages and technologies used.

I use Pandora FMS which is a decent free solution. PRTG is another free one up to 100 devices if I am not mistaken.

I think that's a different class of network monitoring. One approach would be to write a script for it that pings hosts, attempts to connect to services, etc.

Try tshark via a Linux terminal. You can filter the output to show just the protocols or addresses of interest - see the documentation for details. It is a while since I've needed it, but I have successfully used it.

Hi.

Been a while since I tried. Will be watching this thread.

I tried NtopNG briefly. This produces stats and info you can look at in a webpage. It requires a paid for plugin to work with netflow if I recall. I need to have a look it again actually. Not sure I configured with SNMP.

There's also cacti which can collect SNMP data, display graphs and stats in a web interface.

There are quite a few for SNMP collection actually.

Active analisys. I'm sure you know but if using sniffing, AKA traffic analysis, it's important where you place the sniffing system. My NtopNG was a VM on a virtual network between some VM hosts and a virtual upstream router. SO snaffling up all traffic that traversed the link.

There's also cacti which can collect SNMP data, display graphs and stats in a web interface.

There are quite a few for SNMP collection actually.

Active analisys. I'm sure you know but if using sniffing, AKA traffic analysis, it's important where you place the sniffing system. My NtopNG was a VM on a virtual network between some VM hosts and a virtual upstream router. SO snaffling up all traffic that traversed the link.

Hi all,

Anyone using some linux software to monitor a network? I want something that prints stuff out in text on a web interfaces. at least the most stuff i would be grateful. Want to install that on a raspberry pi to see what the network devices are doing. so support for snmp and other protocols would be nice.

anyone has an idea?

Greetings, Simon

Hi, I guess nagios or ikinga or munin does that? Greetings, Simon Am 02.09.2017 um 18:45 schrieb Jason White:

I think that's a different class of network monitoring. One approach would be to write a script for it that pings hosts, attempts to connect to services, etc.

Hi,

Thanks for that as well. I am also on search of a network monitoring system that can check health of computers, servers and different services. anyone has a tip? thanks.

Try tshark via a Linux terminal. You can filter the output to show just the protocols or addresses of interest - see the documentation for details. It is a while since I've needed it, but I have successfully used it.

Yep Tshark and Tcpdump are both good. They use the Berkley Packet Filter sintax. Using with grep, awk and sort can narrow down what you're interested in. Again, you need to have them on a promiscious interface at a suitable place on the network to capture packets off the wire, assuming we're talking ethernet not wireless. I actually bought an old dum layer hub for this a while ago though not used it much. Otherwise you could put your sniffing system on a mirror / span port on a switch. Regards.

In tshark, you can perform the filtering internally with its own filter syntax. I can't remember the details - I always have to look up the manual page. -----Original Message----- From: Chris Turner [mailto:ultimatethesecond@googlemail.com] Sent: Friday, September 1, 2017 6:22 PM To: Jason White ; 'Blind sysadmins list' Cc: 'Chris Turner' Subject: Re: [Blind-sysadmins] network monitoring Yep Tshark and Tcpdump are both good.
