Nice @srosen. I've been wondering about the exact same setup where I wanted to spotlight a particular building @ ~1km with something high gain.

Hi Mrz, Certainly excellent news. I look forward to seeing the improvements. Regarding issue 1, a single common RD is certainly a valid config and the overwhelming number of examples on the internet (including Mikrotik's documentation) use the same RD across all PE's for the same customer/VPN. Many ...

Hey all, Can I confirm with you guys that this is the same issue(s) I've been trying to debug recently with duplicate prefix adverts into a VPN. Scenario (lab) - simple 3 PE node MPLS network, and for the most part, working as expected. 2 CE's, each connected to one of the PE's. Both CE's injecting ...

richinuk

You could use a variation on port knocking but using icmp and various packet sizes.

Then the client can use the ping command with size set to execute the knock

Hope that helps
Nick

Ooh, I like that. ICMP packet sizes are also pretty obscure to someone sniffing the wire.

richinuk

There is no point purchasing a licence as you will never be able to activate it without internet access.
You might as well use the free one.

Ok, I may have over-emphasised the "never" bit. I can give it internet during the setup and configuration, but once it goes live it's offline.

richinuk

Nice job on the 60G stuff. Any datasheets? Antenna/radio specs etc so we can do our own link calculations?

richinuk

It works. I'm using on VMware and as long as you set the MTU on the VNIC to, say, 9000 then you can use large MTU's on the CHR guest.

richinuk

Did you see this thread: http://forum.mikrotik.com/viewtopic.php ... 00#p559990

This would be an excellent product.

You would clean up from the fibre and cable companies in high density urban deployments. Virtually no interference and an AP every ~500m.

Hey Normis,

Thanks for the update. It was Feb 2015 that I asked the question, so obviously plans change. Any idea on when the OmniTik AC will be coming?

Hi MT,

I couldn't find if this had been discussed already, but does the CHR fix the issue with large L2MTU? I know we had issues before CHR when using x86 RouterOS on ESX and MTU's above 1500. If so, what is the max MTU for CHR?

FWIW, I've been using the PSC-60B-C on smaller systems (9ahr) and it is working well (~4 months now). Not the 110+ah you're asking about, but just thought I'd mention that I've tried the PSC range with success.

richinuk

Which wireless protocol? NV2. In fact I saw a couple of issues. One as explained above - when a new station associates it starts at the lowest rate. All is fine until the new station starts transmitting. It will then draw down the AP to it's level until it finishes training to a higher rate. Second...

richinuk

If you're confident the link will never drop to very low speeds, you can disable the lower data rates so that it only ever "starts" at something reasonable. The problem I've found with starting at 6mbps is that the "newly associated client" will slow the whole AP down until it &q...

Yes, true. NV2 will schedule packets based on the EXP bit. But there's little control that can be done here, and NV2 only handles scheduling, not throttling. What MT said, which I agree with, is that any throttling has to be done on the ingress to the VPLS interface, because once the packet is encap...

richinuk

I believe he means that you can't shape / qos once the traffic has been labelled and is being switched through the network. Filtering / shaping / qos etc should be done as the traffic enters / exits the VPLS tunnel (for example, as you say, on the VPLS interface itself).

Hi Normis, I also want to use this type of setup, and I see there has been other threads discussing about USB power injectors on 411's. I'm unsure which routerboards need power injectors and which don't, as I'd prefer to avoid using them if possible. Which RB should I buy? And do I need a powered US...

Hi Myron in router-a i can ping 10.13.0.2 but if im in router b it wont ping 10.13.0.1 using laptap connected to 10.14.0.0/24 If you're trying via a laptop connected to router b, then also check that your laptop has either a default route via 10.14.0.1 or has a route to 10.13.0.0/24 via 10.14.0.1. &...

Thanks Sergejs. For some reason searching the wiki for "user manager" didn't find this.

Hi All,

Can someone point me at the changelog for User Manager 4 please. Can't seem to find it referenced anywhere.

Does each chain (or antenna port) using .11n use a seperate 20Mhz channel or do they all share the same 20Mhz and transmit at the same time and recieve at the same time? I've not found any good documentation to explain that. they all share those 20mhz and transmit and receive at the same time. Hi U...

Glad it worked for you Tom.

Actually, do you mind emailing me on rich (at) goode.me.uk. I wanted to discuss something offline with you (and PM's are disabled on the forum).

Will MetaRouter run on x86 hardware, or just routerboard? I'm using x86 based servers in a co-host facility.

Is there any feature difference with Xen and MetaRouter?

richinuk

Thanks for posting that hush. I was about to upgrade my 3.22 Xen machines :) I think I'll hold off for now. Whilst Xen is very useful (particularly if you're trying to save on datacentre hosting fees), it is still a bit buggy, and I believe MT are openly stating that Xen is in an "alpha" s...

richinuk

Hmmm... this does seem a little odd. How much RAM does the machine have anyway? I'm a bit suspect that your "main" MT is still showing over 300mb of memory when you've set the limit at 128mb. When I first started playing with Xen I had a number of very similar issues - ie: VM fails to star...

Hi Tom, Just looking at what you quoted: /system resource> print <...> free-memory: 321336kB total-memory: 353040kB <...> /xen global-settings set memory-for-main=128MiB You have the main memory at 128mb, but your /system resource print is showing 345mb. Have you rebooted the box since applying the ...

Hey Trydon, What you're trying to do should be possible. I have an almost identical setup - PC with 80gb HDD running MT3.23. My Xen VM's have two images (two virtual drives each) one being 20gb and the other 30gb. I didn't try loading with SCP, but used FTP instead and worked fine - just took a long...

richinuk

For what it's worth, I had the same problem on a recent version (don't recall the version, could have been 3.23). I removed my walled garden rules and re-added them and they started to work fine.

Hi all, I keep coming across this problem / bug whereby OpenVPN stops responding. I have it all setup fine and working, but it is in an experimental stage. From time to time I'm changing something like the certificate, or possibly moving from port 1194 to port 443. I find that often when I make a ch...

Hi guys, Just posting this incase someone else has the same problem. I'm running MT 3.19 on an x86 server with 512mb running with 1 256mb Xen instance. The Xen is running the CentOS 5.1 distribution that MT prepared and is linked from the wiki page. The Xen has a static virtual ethernet running priv...

Actually, as I'd finished writing the above, I found the fix, but thought I'd post it anyway incase it is useful to others. In the Centos image supplied, the /etc/modprobe.conf needs to be modified to use the xennet driver. So, as supplied with the image, /etc/modprobe.conf looks like this: alias et...

Hi All, Anyone got an answer to this problem. I'm running 3.19 and have a VM configured and running successfully using the Centos image posted on the Wiki. However, I'm having problems with the ethernet config. It all appears to be configured as per the wiki instructions, but the vif never goes to a...

Hi all,

Hopefully an easy one I'm overlooking... how do I see ethernet error statistics?

Thanks,

Hi Webor / All, I don't have a solution to offer, but wanted to chip in that I am having an almost identical issue. My setup is fairly typical... WinXP SP3 -> NAT/PAT DSL -> Internet -> MT Server (no natting - direct on the internet) However, what I can see from my debugging is that it seems that L2...

Hi Sky, There was a tiktube on this topic from Concourse Communications. See http://www.tiktube.com/?video=119.

Thanks for the replies guys. My first "guess" was to budget to replace hardware every 2 years due to failure... seems I may have been a bit over zelous - works wonders for my budgets of course

Thanks again.

Depends a lot on weather. How much lightning a year? Mostly radio card that have problems. Also depends on where installed. So weather wise I need to consider typical English weather. So, say, from 0c up to 30c with a lot of rain, and occasional lightening. The units will be installed below roof li...

Hi all, Does anyone have any figures (either factual or estimates) on the MTBF of RouterBoard hardware? I'm costing up a hotspot rollout and I need to include a contingent in my budget for replacing failed hardware. For example, should I expect a board to fail after 3 years of service and therefore ...

Hi Mplsguy,

I'm also interested in this exact setup, so thanks for posting the config.

Tprice, I just tried this out on a network of 5 vmware based MT 3.10 machines and worked straight up. Maybe you have something missing in your config?

Hi guys, I've noticed a behaviour change between 2.9 and 3.x with OSPF. I have my OSPF setup with varying interface metrics that I tweak from time to time depending on link performance. Under 2.9 I could change an interface cost with no problem, but under 3.2 whenever I change an interface cost, OSP...

I've not used ESX, but have MT 2.9 and 3.1 successfully running under VMWare workstation running about 8 instances simultaneously. 1. Create the VMWare machine using the wizard 2. When finished, select "Edit virtual machine settings" 3. Remove the hard drive that it created 4. Add a new ha...
