I don't know if this is the right place, so please move this post if it isn't. I am very pleased with the recent evolution in Winbox but I would like to report a bug. I still have some routers running RouterOS 4.17 and, after Winbox v3.0rc12, when I access those routers, I cannot view the PPP menu i...

My existing netflow collectors are based on fprobe running on Linux sending to pmacct, which works for me so far.

Hi, could you post the fprobe configuration necessary to collect netflow from Mikrotik? I wish to use it to send to nmapng without having to pay for nprobe.

Thanks in advance!

I have been waiting a long time for:

*) new RouterBOOT firmware for Metal 2SHPn to improve wireless stability;

I am going to test this right away... please can anyone with wireless problems in 2SHPn report here too?

Thanks!

parrini

Really great post Sob, but the feature request to Mikrotik still stands, right?

parrini

Use different pc users: each users has is own address list... I am sorry but I don't understand... are you suggesting to create one windows user (with all the folder structures behind it) per routers group and switch windows users to alternate between them? I know each user have a different winbox....

parrini

Our networks have grown -a lot-, and nothing beats Winbox when it comes to speed and lightness... Compared to Winbox, a browser is an elephant. I bet you guys use Winbox there on Mikrotik Headquarters, :) A simple command-line parameter allowing to open winbox.cfg from a different place would suffic...

parrini

Same problem here, Metal 2.4, version 6.10, up to 3 wireless freezes per day, only reboot to bring back.

parrini

That is REALLY similar to our setup.

I'm gonna make some upgrades and report back here.

Thanks!

I don't understand the line "At the same time ..."Is it good, better now with 5.8? Yes ... much better. Those marginal signals CPEs for instance, sometimes I need to gain access to them to trimm one parameter or another (e.g. change CPE speed algorithm from EWMA to conservative on UBNTs C...

Hi all. Recently I have been following 2 threads, one (http://forum.mikrotik.com/viewtopic.php?f=7&t=31426) states that ROS 3.23 release is the best performing until now for Point-to-Multipoint with mixed clients, hidden stations, environment. This makes some sense because 3.23 reenabled CTS res...

parrini

Another guy said that 3.23 was the best ROS version he's ever used with mixed bag of clients lol - what a difference in opinion... You guys should compare notes. Scott :lol: it makes sense because of the RTS/CTS revival, especially in a mixed environment. Anyone else with a mixed environment, point...

Hi People.. I Have a really disturbing problem , i have a 3.15 Mikrotik RouterOs Working on a P4 2GBRAM 160SATA H.D PC its works good and all interface are read...the only problem that i have is it keeps on freezing on me after running for a while i have like 15 users only and its just goes dead .....

parrini

I'm going to add that it appears that MT ros3.23-MT Ros 3.23 seems to work fine.
The problem is isolated to MT-UBNT, .*

Having any progress with this issue? I agree that this maybe related to the return of RTS/CTS responses, how are your UBNT configurations for RTS/CTS?

This scheduler bug has been around for most of v3! see: http://forum.mikrotik.com/viewtopic.php?f=9&t=22675 it can have a snowball effect if your 24hr or even 48hr timed scripts call other scripts in their runtime - you will end up with the same script running twice concurrently and on some occ...

may MT confirm the HCI fix is inside the 3.15?

Sorry to "hear" that.

I am using in 2 different machines with SMP enabled. No problems so far.

parrini

I dont think there will be any backports to 2.x series anymore because the versions are too different. But, bug is the same. The problem is that, fixing bugs in two releases, duplicates the work and defeats the purpose of releasing a new version. It's true that the release system of MikroTik could ...

parrini

5 days, no crash.

But this is only my experience, YMMV. I don't know if everybody that is having this issue have a similar hardware setup.

Since RouterOS is bound to the disk only, worth a try...

parrini

What about 2.9.52 ?

I dont think there will be any backports to 2.x series anymore because the versions are too different.

parrini

I had a similar problem here and, as a last desperate resource, exchanged hardware for a more powerful x86 platform (from Athlon64 to C2Duo) and the problem just disappeared. I just couldn't believe since the Athlon was running only about 20% of CPU, now the C2Duo is using SMP and running about 1-5%...

Anyone tested this (USB or Sata+CF) on ICH9 against 3.14? It's getting really hard to find older motherboards and I am reluctant to buy new ones...

parrini

1480 MTU and MRU. For ICMP you have to choose what you want to pass and take into consideration the direction of the packet. I think your selection is ok, Type 3 Code 4 should take care of fragmentation. Maybe you should also consider Type 30 (Traceroute).

parrini

More than changelog...

parrini

Well, I have asked this before here, without success. I use 1480 on the PPPoE server profile. Apparently everything is working fine.

parrini

Yep... missing a segment...

parrini

Anybody knows if this has been fixed in the final 3.14 release? The changelog says nothing about it.

parrini

Is there anyway to help?

parrini

Wow! This is a huge accomplishment!

Congratulations MT guys, hci for the teamwork!

Normis, do you have any idea of when this fix will be rolled out?

parrini

It has nothing to do with that. Drivers that are not digital signed is a matter of Micro$oft wants money for signing drivers and a lot of of vendors doesn't want to pay them for that. I think it's related to a bug in the new release (new linux kernel) /Henrik Sorry, I did not said that I came to co...

Does anybody knows anything else that can replace PPPoE in Vista, just like RASPPPOE does to 98/2K/XP?

parrini

Be careful. MAC can be **easily** cloned.

Don't you have to go to Mangle, mark connection in prerouting, then mark packet in prerouting, then drop in Forward?

That´s the way I am doing, am I missing something?

I am running a PPPoE server on RouterOS, my PPPoE clients are mostly Windows machines. Here's my doubt: I know that PPP has an overhead so I must adapt the MTU/MRU but, this adjustment must be done in the PPPoE server running on RouterOS (eg. lowering MTU/MRU from 1500 to, say, 1480) or I must leave...

parrini

Thanks man! I'll give it a shot, looks like Vista's PPPoE is pretty bad.

Anybody else experiencing PPPoE problems with Vista?

parrini

It's the Vista's built-in PPPoE.

Are you familiar with this PPPoE over WPA problem?

Do you recommend those third-party PPPoE?

parrini

*** BUMP ***

Anybody?

parrini

OMG! But If I were you I wouldn't rely on finding a board with so many PCIs for much long. If you find a supplier try to buy as many as you can for backup because it seems PCI isn't going to stay for much longer. I just hope MikroTik starts to sell PCI-Express NICs soon.

parrini

Maybe invert the queue order? I have a similar setup here but I enable/disable the smaller speed queue depending on daytime. I put the smaller speed queue first and the biggest speed queue after. Apparently it works fine but after your post Ill check everything =)

Look, on my first post the first link was wrong. I edited and it is correct now.

anyone who can give full remote access to your router (with missing queue problem - where queue is shown, but not working for the specific customer), please contact support and we will look !

Please, if someone could do this it would be of great help!

parrini

Ops, maybe we are being misled to believe the clients are using the extra bandwidth without actually using it?

parrini

Can anyone confirm this?

parrini

Looks like we are going to know in a few days if the problem with the queues (not limiting bandwidth some times) is fixed by 3.13, there are a few people testing it right now.

Oh, and another quick suggestion: As a Sys Admin like all of you I don't have time to check this forum so often.

The group key is used to do broadcasts in the wireless network. Without it, it wouldn't be possible to talk to all stations at once since each have a different dinamic key.

parrini

You cannot adjust the power output on a prism card. Use a long jumper...
What you mean with "long jumper ...." ?

I think he means to use an extra long cable (jumper) to connect the antenna to obtain signal attenuation trough cable loss which is usually known and well documented.
