At the moment someone is experimenting with Zabbix as an alternative solution. For monitoring the routers I am also looking at MikroTik's "the Dude", but I am not yet sure if it is useful. In Nagios we have 114 hosts and 297 services being monitored. Rob

Re: [44net] Example of nodes monitoring

by Steve L

Thanks for the info. I had not heard of mutiny before. I have played with Cacti though. A couple years back I tried to nmap all the connected address space to get an idea of what is out there: http://www.qsl.net/kb9mwr/wapr/tcpip/amrprnet-nmap-2014.txt Looking back I feel a bit guilty about doing this as some of the radio links are slower ones. I wish under the gateways tab of the portal there was a check box to signify 1200 baud or hsmm. Of course I wish a lot of things. I had a script grab an encap file and merged that with the 44 BGP list and had a script incrementally nmap each connected subnet.

Example of nodes monitoring

by Jean-Marc Magnier

Hi, For those interested, the following link shows how can be monitored nodes/gateways. http://44.151.178.254/views/index.do?view=cvwg Only hardware is monitored. 73 de F1SCA

split subnet

by Tal Raveh

Hello, I got subnet 44.138.2.0/24 Can I split it to few defrent subnet ( i have few locations) ?ind it in my portal something like: 44.138.2.0/29 (which give me 0-7 ) 44.138.2.8/29 (which give me 8-15) in the portal I can take my full segment. another question, where can I enter dns record ? ( I can't see it in my portal). Best Regards, Tal Raveh 4z7tal

Making Gateways With Home Routers ?

by Rob Janssen

> I'm testing this with Marius...the script is cpu intensive and most > likely not a candidate for a MIPS type processor. I'm testing with a > 1200mhz celeron (old watchguard hardware since cpu) and it goes 100% Ok... is there any obvious reason why this would happen? It did not appear to be all that complicated, and it is scheduled as a repeating job so even when it uses some resources for some time it should be idle most of the time. I have no immediate intention to use it. Marius also suggested the use of metarouter, but of course this does not make things easier for those users who want a simple system. (with 2 different environments to configure and the need to have either binary compiled ampr-ripd or a cross-compilation environment on a PC or similar) After all, the Raspberry Pi may be the simpeler solution :-) Rob

Re: [44net] Making Gateways With Home Routers ?

by Rob Janssen

Sorry for the layout mess in the previous post!! > I saw that Microtik Routers support IPIP by default > Is it possible to make a gateway with home routers ? > If yes how to deal with 300 tunnels lines to the rest of the gateways on the net ? will a home router have enough memory for that ? Look what Marius posted yesterday. He has made a script for MikroTik routers that updates the configuration using the AMPR RIP transmissions! This is a very nice solution because it will receive all current routes automatically without requiring an external computer. MikroTik routers are very versatile. They can run user-written programs (scripts) to do things like this. I have a MikroTik RB2011UiAS-2HnD here, which would classify as a home router. It has 128MB RAM and 128MB flash which is more than enough for this purpose. I paid 125 euro for this nice box. They also exist in rackmount version, and we use these in our digital network. And they have a nice web interface that actually is usable also for advanced things. (contrary to some other manufacturers products where the web interface is only for rudimentary tasks and advanced things are only possible via the command line) I have no experience with the script that Marius posted yet, as I do not run IPIP here at home, I use IPsec VPN from the MikroTik to my Raspberry Pi in a datacenter which does IPIP. Notice that for best results (and less headaches) you need to put this router directly on a public IP, not behind a provider-supplied router that does NAT. Either put the provider router in transparent (bridge) mode or omit it completely. (depending on what connection you have) Rob

RIP broadcast based AMPR gateway script for Mikrotik routers

by Marius Petrescu

Hello, For thos who like experimenting... I managed to implement the complete AMPR gateway tunnelling setup on a Mikrotik router by a scheduled script on the router only. Tested on my RB100AHx2 with ROS 6.34.2 You can find it on http://www.yo2loj.ro/hamprojects/ Direct link: http://www.yo2loj.ro/hamprojects/ampr-gw-1.0.txt Setup details are in the initial comments of the script. Enjoy. Marius, YO2LOJ
