Re: SSH authentication issues

No configuration changes at all, this happens randomly. This isn't someone going on and changing details, this is the routers randomly becoming inaccessible with previously correct logins. To add to this, I get a very different SSH failure reason. This is an example of what happens when I use an inc...

SSH authentication issues

Hey all, I currently have an issue with SSH on an estate of routers. We have our public keys on them, but every so often, the routers will not accept our logins. When this happens, we can log in to the router with the username "admin" and no password. Any attempt to change the admin password and put...

Re: OSPF Multiple Instances and External Routes/LSAs

I'm not sure if I'll be able to conform to the guidelines of the support instructions (as it says to raise based upon a single system, and this is currently affecting a live deployment of 50 MikroTiks, and another 5 in testing) but I'll email that.

Re: OSPF Multiple Instances and External Routes/LSAs

What do I have to do to get any support on anything? Two topics in a row where the only person replying is myself. I'll be glad to get these things out of my network if this is the level of support I can expect.

OSPF Multiple Instances and External Routes/LSAs

Given my previous topic has been so popular , I decided to try and work around the issue by using multiple instances of OSPF, one based in a VRF. However I now have a new problem. http://i.imgur.com/u2hO1.png Same diagram applies, and I have the following configuration running on the Core routers (w...

Re: MPLS VPN and best path selection

To add further to this, I now have the routers disagreeing with their own routing table: - 07:35:37 route,debug,calc Route to destination 07:35:37 route,debug,calc rd 07:35:37 route,debug,calc type=0 07:35:37 route,debug,calc administrator=65009 07:35:37 route,debug,calc assigned-number=1 07:35:37 r...

MPLS VPN and best path selection

Hi there, We have recently seen a problem where the MPLS L3VPN implementation does not seem to take into account the BGP best path selection algorithm. We have two routers, one with a lower router ID than the other, both putting out routes. The topology is as follows: - http://i.imgur.com/u2hO1.png ...

Re: MPLS EXP bit and matching classification

Not a problem, a quick view of the problem I have http://www.workingfrommyshed.co.uk/guff/network.png The above is an overview of the design I'm looking at. Nothing particularly special, but anyway. The outline is 1) The links between R1 to R2, R2 to R3, and R3 to R4 are leased lines 2) The link bet...

Re: MPLS EXP bit and matching classification

I'll take the views without any reply to mean either no-one knows, or nothing has changed. No worries, I'll just try and find a hack to get round it....

Thanks all!

MPLS EXP bit and matching classification

Hey all, I've seen some forum posts saying that it wasn't possible to match on the MPLS EXP bit when in the middle of a label switched path (so only ingress and egress would ever use it due to the value being copied into the IP header). However these posts are a couple of years old, and I haven't se...

Re: 30-32mbps only

Welcome to the wonderful world of 802.11 and marketing. Basically the 65 mbit is the raw low-level speed, before overhead has been taken into account, and 802.11 has significant overhead. This is why some alternative technologies seem slower, because those technologies quote the actual speed you wi...

Re: Winbox on Linux?

I've had this issue before, but it was on Ubuntu 7.04 I think. I forget where it was, but I think it's a file association. Try open with... and set to open with wine. It was a long time ago, so this may not be relevant for you. Based upon the error shown, it isn't that which is the problem, its tha...

Re: Winbox on Linux?

Open a terminal, and navigate to where the exe file is, then do "sudo chmod 755 winbox.exe", try it after that.
