MikroTik

What to do with used MikroTik equipment?.. . We have about 250kg of used MikroTik (and others) WISP equipment, About 300 CPEs and other stuff... mostly we have upgraded our clients to better faster technology because they want to watch IPTV 24/7 etc... This kit, it's all a bit too good to scrap... ...

I need to make a simple foolproof solution to configure multiple routers. While flashfig is a useful tool it requires time, minor skills and some attention... Starting a windows PC, getting the right file etc. A quicker simpler one touch/hands-off solution is needed in my case. My idea is to substit...

Nick Kett

Hi, I too want to do this... but from the DHCP/TFTP services on another mikrotik router. IE, I want to be able to send the rsc file from a mikrotik "server" via flashfig when I plug-in new routers. I can get the file transfer via bootp, but don't know how to compress the file beforehand. D...

Thanks Normis,
An Answer like I was hoping for.
I can see many use cases where it will necessary to run AP and Mesh in 60 GHz campus backhaul type solutions.
You will sell more quantity for sure.
60G... "its wifi, but not as we know it captin!"

We have been testing a pair of Wireless Wire devices, very nice they are too. It is posible to observe the beam Forming antennas in operation. Change the angle of one of the antennas, you will see the signal drop, then in a few seconds recover, as the automatic beam forming re focuses the signal. My...

Thoughts on Bandwidth testing and Mikrotik. Using mikrotik you can get two very different results depending on if you use TCP or UDP... basically: UDP will give faster result because it ignores any smaller packet loss and just keep stuffing packets down the link until it is full.. Not a very useful ...

Nick Kett

Hmmm
I beginning to think the "cloud" in cloud core refers to the smoke they emit.

Nick Kett

Over the past two years we have deployed 6 CCR1036 devices. To date we have had 50% of them fail... they either just go dead, or into terminal reboot cycling. On investigation the problems have been. One unit with failed power supply. One with melted heatsink cover and CPU fail. One with blown on-...

Nick Kett

Maybe I'm missing something, but I cant find "MAC cookie feature " in ROS Ver V 5.25 (mibpsbe).
Is it available yet? reading the wiki it should be an option in hotspot user profile.
Anyone seen-using it?

Nick Kett

Dude has not been updated for years, and is not support on Cloud Core.
Can we all assume Dude is Dead... No more development?

Nick Kett

Now Dude support for new releases is terminated. Looks like the Dude is going to die. Not supported on cloud core routers? I would have thought Cloud core would have made a good platform for Dude. What a shame.... I can't pin the dates down from the change log (good logs have dates), but I think th...

Nick Kett

Will dude ever branch to run on Tile CCR Architecture?

Nick Kett

Yes I want it.
Encription is not an issue, there are already many solutions in MT.. even good old RT tunnel should work

In a previous life I engineered data links to oil production platforms in the uk north sea. The problem is this, on a calm day the sea is a good reflector, and you get two signals hitting your receiver, one direct and one via reflection. This causes two problems: 1) Delay spread, because the reflect...

Nick Kett

In simple terms a PON is an optical network, where upstream and downstream data paths are combined/split using optical spliters. For a better understanding read: http://en.wikipedia.org/wiki/Passive_optical_network . Whilst ITU standards already exist for the implementation of PoNs, G.938 and succes...

Befor I splash out to buy some surplus Dell PowerEdge 1850 with 2 x 146GB SCSI Hard Drives and Integrated Raid (PERC4) with 256mb Cache, does anyone know if ROS is likley to see the drives?

Also if the GigEther drivers will allow L2MTUs greater than 1500 ?

Nick Kett

My configuration scripts (that I use to load a standard configuration)that were running fine in 5.2 (and for a long time before) are failing at multiple points in 5.4... Before I get down to the nuts and bolts of it, has something more material changed with the OS that I should understand ?

Nick Kett

Problem with Queues. We upgraded a core router from 4.x to 5.4.. The router (HP ML310) has some simple queues to smooth trafic flows. Soon after the upgrade we had a number of reports of specific web sites being offline or very slow loading, for example http://www.monarch.co.uk After some investigat...

I can see how to use the system note.
system note set note="blahblahblah"
But please anyone know how I can escape a caridge return (CR) in the text .

The modification is a "drainage" hole. The SXT already has two sets of "breathing" holes by design. The front of the enclosure simply clips on without any seal or gasket the total length of which is 42cm. The Cable entry cover also has no seal or gasket the edge or which is 17cm ...

Nick Kett

Come on... We are talking Micro electronics here... PCB tracks with 0.1mm clearance, Sub miniature components with sub mm dimensions. Up to 27VDC (boy does DC track!) There should not be any water or condensation in the same enclosure as a routerboard. Anyone want to disagree with that? Breathing Ho...

Nick Kett

Also we use a simple wall bracket, like you may use for a Nano, a TV antenna, Satellite dish, etc... (most brackets/poles are vertical did you notice?). But If we want to use vertical pol (most 802.11a systems are vertical), then we have to mount the SXT 5HnD's on a Horizontal bracket/pole, that's n...

Nick Kett

From the STX Manual: "If you want to overcome certain obstacles or interference by using only one polarization in 802.11a mode, you can switch off chain1 of the wireless device. When chain0 is used, the device is horizontally polarized when mounted as indicated in the Mounting section of this d...

If you are thinking of designing a pcb/kit how about integration for a GSM module. Such as http://www.mikrovlny.cz/en/product/44 ... KIT_en.pdf would add full out-of-band site alarms and re-boot facilities via SMS/GSM. As an "add-on" PCB it could be linked-out if not required. Maybe it wou...

Nick Kett

Nice one Adrian. There are not many commercial products out there that address our needs. will you be producing a PCB? Thought I would take the opportunity to proffer our solution. We are currently using a somewhat more expensive, but very simple solution, which relies on two basic principles. 1) It...

Yes Asterisk works with Mikrotik.

We have used the balanced rr (round robin) mode, but it has problems. If there is any differance in latency between the links (or maybe bigger and smaller packets at some point) then packets become disorded at egress from the routers. This we noticed causes two main problems. 1) Many voip providers ...

Same problem here with HP prolient ML110 G4 server Dual Xeon processor. Runs OK until the router is stressed in some way, running the bandwidth test tool for example. CPU usage goes high and stays there, even without any load. Clock starts jumping several seconds per tick All statistics are wrong by...

OK, This project was on a new server,,, when we upgraded the server (Hardware only) I also upgraded from Dude 2.1 to Dude 3Beta6...

Spent a lot of time seting up Dude (50 hours)....
My server had a power outage, all the config files are gone...c:\programe files\dude\data\files all are reset to new installation defaults... discovery isn't smatrt enoughf fo my network... I'm running 1.0rc7. what to do?

Nick Kett

The PNG export function is useful, but If dude had an auto-export configuration that could write to file a png of any map of X,Y dimensions at defined time gaps (or maybe change of status) then the map could be used on a web server to show current system status.

Skype will try to use random ports >1000 first, then port 80 (http), then port 443(https). I know of no firewall rule that will match skype traffic, not even P2P-all works. So here is another way. 1.

But Operators own the network...not the end user, QoS, capacity, billing, and technical standards are the operators responsibility, control of the networ stops at your modem!

Nick Kett

Is anyone blocking Skype on packet length ?

Nick Kett

you could try allot's bandwidth shaper the "NetEnforcer".. we are currently using it and it can detect P2P applications as well as every other protocol on the network and you can set those to DENY.. I'm not sure if it detects skype but they continually update the software for new protocol...

Nick Kett

Truth is the vast majority of the customers only want WEB and e-mail, and yes it isn't just Skype, it is all the others you mentioned and then some. Satellite backhaul, and We block all outgoing ports exept, SMTP, https, PoP3, ftp and http is via proxy. Skype we limmit by only allowing 30 second bur...

Nick Kett

What do you connect your wireless to if you are more than a few 10's of miles from the nearest internet POP? In very rural areas, the only viable access is via satellite, many people are 100s if not 1000s of miles from fiber.. And fibre is only cheap in well connected locations i.e. more than one pr...

Nick Kett

Almost Back on topic at last! Yes billing by the GB is also an option, but there is also a question of QoS. Satellite bandwidth is typically very asymmetric. The in-routes (traffic coming back to the internet) are usually a small 20% of the out-route size (download). Sometimes this may be just 64 or...

Nick Kett

I could block skype on ports 80 and 443, if I could set firewall rules to only allow http or https on these ports. Anyone know how to match only these protocols on firewall ? Another way to stop Skype would be on packet length,(skype packets are unusual lengths). I can do this with Cisco, but the fu...

Nick Kett

You can use a convertor outside the box for 3GHz.

Nick Kett

Thats an easy one to answer. Cost of providing an Internet connection via satellite is up to $10,000 per month for 1Mbps. If everyone on that link uses skype then you will need 10 times this. Now imagine you are in Africa and satellite is the only connection available, and you can only just find the...
