RouterOS 5.0 is out!

Mon Apr 04, 2011 3:02 pm

So is the BGP memory leak fixed?

I'm still running 4.13 that came installed on our RB1100, but it's leaking memory running BGP. We're taking full routes from one peer and just default route from another. So about 350k prefixes. Memory use seems to creep up... And now I'm wondering should I just go to 4.17 or 5.0 here.

(as you can see, we started running BGP mid-week 12)
I've tested 5.0 on a RB1100 with a full BGP feed. CPU is at about 80-100% usage constantly. MT says it has to do with new routecalculation and that it's 'normal'. I'm going to run with three (maybe four) full feeds and will be buying x86 hardware for that.

IMHO, the RB1100 with 5.0 is not suitable for full BGP feeds.

This is correct, that in v5.0 you will see higher CPU usages with BGP. It is due to more frequent nexthop calculations which is made to address several problems where nexthops were not updated correctly. CPU usage depends on how frequently peer receives updates (more frequent updates will cause higher cpu usage).

We are working to improve performance, but until then users who experience too high CPU usage will require faster hardware.

Beccara,

And THAT is how you say a feature that was in testing has been removed from release

Read again my post. We haven't removed anything, you can still choose Nv2 protocol on x86 router.

Mon Apr 04, 2011 3:07 pm

Uldis That will tell about the report nv2 on distances more than 40 km ?

Whether the help in testing is necessary?

Please write to support with that report and include the support output files, we will try to look more detailed.

I resulted schedules above
At what moment to do "support output" communication normally only for not clear reason fades or reconect. Sometimes even wotchdog works thus on nstreme 100 % quality
Why on nv2 more low signal level??
Same the transmitter and receiver characteristic instead of the protocol?

Where and with what heading send files ?

So is the 1100AH enough hardware to throw at a full feed BGP router? I do not want to go to x86 hardware, BGP is the reason I bought a RB1100 in the first place... And if I can get the CPU to handle it, is the memory leak still there?

We are not able to repeat any memory leaks in v5.
In our tests RB1100AH handles two BGP feeds without any problems (max CPU usage during frequent updates is 48%). However Jeeves have peers that sends updates more frequently and his RB1100 is unable to handle it (CPU is fully loaded constantly).

HAS SENT ON MAIL FILES
I can give access and include by turns different protocol

Then for communication write icq or skype

i have a wds link on x86 P3-1000 with 5.0 and nv2.Its online 4 days and seems stable.no disconnects, no freezing.With some rc`s router was freezing with nv2. I have configured watchdog, if freeze will accour, i will have supout files....

Egate · Tue Apr 05, 2011 10:05 am

Virtual Ap seem to still be not working. Is this correct?

Tue Apr 05, 2011 11:09 am

Thank you very much for your reports and comments.
Please, start new topic for specific features discussions and problem reports, otherwise it is too difficult to follow up different issues in current thread.

Beccara · Tue Apr 05, 2011 1:01 pm

Just wanted to say a big congrats to MT on the 5.0 release.

So far in our experiences ROS X.0 releases normally have a major bug or two that take a while to fix or have some big issue that stops us from deploying it on even one production CPE but ROS 5.0 release is the best we've seen out of MT. We've deployed this to RB112 and RB133's running either 2.9.51 or 3.30 because ROS 4.x simply slowed them down too much and made them go funny, upgrading from 2.9.51 even tho it takes a couple of hours to ROS 5.0 gives them a new lease on life, They are fast and responsive and stable.

So congrat's MT this is shaping up to be a bloody good version

Tue Apr 05, 2011 1:11 pm

Thank you Beccara. Sorry that my previous comment upset you.

Also, I guess we can now move the v5 discussions out of the "beta" forum. Please post all v5 related questions in the "General" or other sections.

Beccara · Tue Apr 05, 2011 1:18 pm

It didn't upset me it's just that MT can be lacking in detail sometimes in their answers to questions on here, I've found in my time personally of supporting users that if you tell them why something wont work rather than it just wont work they are happier overall with you

To the general forums!

Xymox · Tue Apr 05, 2011 1:50 pm

So its time then to start a new beta ? hehehehe...

Im still after HDCPv6

Just joking. Yes im sure you guys will be very busy in the upcoming weeks.

Im very happy with 5.0. I got used to all the new features over the months with the RC's, I can imagine someone going from 2.9 or 4.x must be really impressed with all the new things... Even the RC's have been pretty polished. Im used to other companies RC's causing bricks and all sorts of serious issues. None of the RC's caused me any issues. This has been a very clean development overall.

Hi ,

i just upgrade RB433 from 4.11 to v5 and canot ssh to router .
it accept connection but dont accept password.
Same password works over winbox on same router.

Regards

VirtualAP feature isn't made for the Nv2 wireless protocol. For the rest wireless protocols it should be working.

seems like you're using certificate for that user - that way, you cannot connect via ssh with password; use your certificate. or simply remove all ssh keys

/user ssh-keys remove [find]

xezen · Tue Apr 05, 2011 10:19 pm

usermanager giving problems does it work?

ekkas · Tue Apr 05, 2011 10:51 pm

Usermanager works, but not 100%, there are a few issues.
If you want to upgrade from 4.xx then be sure you don't have paid customers that have time/vouchers in use... Don't ask...
Also don't try and do it remotely, you'll need new setups and train the persons using it for the new way of doing things.

vdeluca · Wed Apr 06, 2011 6:28 am

Got problems on 5.0 on RB1000.

The router runs ok for a couple of hours, but after 3 ou 4 hr running OK, it starts the cpu starvation (100%) and all PPPoE tunnels goes down.

Didn't able to downgrade, or even uninstalling a 5.0 package (tried uninstall ipv6 for example).

All tries is followed by:

dec/31/2001 22:00:01 system,error,critical System rebooted because of kernel failu
re

Send the supout and waiting for an emergently answer, because we are unable to downgrade and having heavy troubles at my core network.

adryfia · Wed Apr 06, 2011 8:10 am

I found bugs in userman v.5.0, in profile can't change when voucher start just start now. Once the voucher is made it will be directly active without user login. So mikrotik team please fix this bugs.

Hello,

I have noticed that in webfig ->IP->Firewall->NAT list the Src. Port and Dst.Port columns are empty while in the same time the webfig detailed view of the rule shows correctly.
This is not a major issue, but it is hard to identify the right rule that needs to be changed.

Thank you in advance.

Is there any prevision to fix the OSPF virtual links?
It's not possible to create a multi-area topology without that.

Thanks.

I have updated to 5 version. I have problems with TFTP provisioning.
I receive the "tftp error ERROR code:0 string:permission denied!" and I need to go back downgrading to 4.17 version.
Thank you very much!.

janisk · Thu Apr 07, 2011 1:42 pm

what tftp entries you have? maybe there is something messed up with address part, that will not allow you to read that file? Please check that.

nahuelon · Thu Apr 07, 2011 6:12 pm

The configuration is too simple.
I have a file called "plus.cm" and only one TFTP entry with Req. and Real Filenameentry "plus.cm".
I do not use regex to write the TFTP entry.
The strange is I have a working 4.17 version, I upgrade to 5 and it doesn't work anymore. I downgrade to version 4.17 and start working ok again. Without any configuration changes.
I you need some screenshot let me know because I have to upgrade to 5 and cut the services (because is a produccion device).
Thank you very much.

Did you set any src or dst address at all? In your case both config windows don't show them.
Double click on the rule to see what is actually set. You'll find much more settings not available in the default colums...

Probably some old sovjet style left over software embedded in MT-Ros to spy on users. Next thing Normis comlains about shoes I'm wearing!

I upgraded an RB running 4.16 to 5.0 that had the NV2 package installed and when the router came back up it didn't have any wireless package enabled and lost all the wireless settings. Is there any way around this issue?

I lucked out in this case because it was the local side that I upgraded, but it could have resulted in a frustrating truckroll.
Same problem. RB433 4.16 to 5.0 Upgrade Fail (Disconnect)
NV2 package has been disabled

I had the same problem.

Transferred 5.0 via ftp to two different RB433AH working on 4.17 (bootloader 2.23) with wireless-nv2 enabled and one R52n each: rebooted and then "wireless" package was disabled in both devices, so no "wireless" tab on winbox at all.

Luckily the devices were connected on ethernet as well, so I had the chance to configure both wireless interfaces again (from scratch).

EDIT: Ok, just got the newsletter and seen it's fixed on ROS 5.1. I'll verify on Monday!

Tanker · Fri Apr 08, 2011 2:04 pm

Just a short note to say thank you for ALL the effort which has gone into V5.0 (and the pre-releases!!)

We have wirelessly upgraded all our BSS & BST's and not one single hitch..!!

NV2 is marvelous and - generally - this version has improved the flexibility and control on the network enormously.

thanks again and keep up the good work.

btw - RB1100AH.. sheeeeeesh!!! - fantastic.
