RouterOS v6.25

Is there yet any news about BGP peer status in SNMP so we can monitor BGP sessions?
How about BGP4-MIB?

Hi,

We upgraded our Routerboard CCR1036 with V6.25 from V6.19 (Firmware was also upgraded). Upgrade was done mainly to solve packet discards on the interfaces.

We have, after a few hours, suddenly lost our bridges inside the bridge configuration, but not the bridge ports which are showing 'unknown' as the interface they should be bound too. Subsequently, some firewall rules are now RED since they depend on these bridge interfaces.

Have checked via terminal to see if the config is a winbox issue but bridges also do not show. Also checked output from an 'export file' command with the same result.

Anyone seeing this?

What model routerboard are you using?

We have a few units with 100+ PPPoE, I am worried to experiment with this.

Do you use RADIUS as well?

CCR1036-8G-2S+
I have about 1200~1500 PPPoE sessions on router.
Yes, authorization by the radius.

I think this problem becomes noticeable with a large number of sessions.

Just installed 6.25 in the IPA Area 0.0.0.51 development lab ( Flowood, MS) and seems to be running fine. Boot times do seem to be improved...Thanks MT!

Equipment we have tested in the dev lab (will update the list as we test more):

Hello,
For me, the 6.25 contains a major bug.
I upgraded 2 CCR1036 this afternoon, and bandwith test tool no longer works, it displays 0bps ... After downgrade to 6.24, the tool works.

Same here, on ONE of our two Omnitiks. Wlan interface became "unknown". For an unknown reason, it was changed to "wlan2" on a previous upgrade, and it was reverted to wlan1, thus becoming unknown.

Previously to v6.25, we had installed 6.21.1 a lot of RB450G had problems with dhcp and dns processes, and the CPU take 100%.
After upgrade to v6.25, most of the problems disappeared, but now we have a few RB450G with ssh process take all CPU. We don't have "idle" process in these RB450G, and the CPU is 100% all the time.

What configuration did you have at 6.24? How did you apply it?
We are try to repeat your issue.

taknamecom,
Do you have the particular problem in the previous versions?
Do you have bridge in your setup?

jarda,
more information is required about your problem.
I have upgraded RB751 from 6.24 to 6.25, admin-mac-address stayed on the router.

siscom, thank you very much for the file.
We are working on your problem.

mickaelmonsieur, please provide us with more information, how you were using bandwidth test on your router.

nkourtzis, please contact MikroTik support (support@mikrotik.com) with support output file, when problem is present.

On this unit, requesting a supout takes forever and seems to trigger the watchdog due to very high cpu utilization during the creation of the supout file.

mail remote access to support for your device, it will be fine too,

Hi,

After updating all my SSTP VPN clients with Windows 8 / 8.1 doesn´t work anymore, error 619 appears and I can not fix it like I did in previous Router OS releases, any idea?

Thanks.

THG · Wed Jan 21, 2015 10:42 pm

Are you going to fix this issue? TCP traffic through the Ethernet interface shows over 80 percent more than the VLAN interface. UDP shows the correct speed on both interfaces and the issue appears only in the X86 version of RouterOS.

dynek · Wed Jan 21, 2015 10:58 pm

Just updated RB450G from 6.19 to 6.25 it never rebooted so I helped it reboot and now it seems to boot OK (one beep and abt 30 seconds later two beeps) but I'm not assigned an IP anymore, none of my devices is.
If I try to set an IP manually, it doesn't work either.

I tried to connect to ether1 with ip 192.168.88.2, no luck either.

Last time I updated I had the same issue, don't think I'll update next time if I can't get the device back on the track...

What should I do ? Reset it and upload backup of configuration ?

1st edit:
So I went for the reset using the internal reset pins, it made the "weird" beep and rebooted.
But even like this I can't reach 192.168.88.1 on ether1

2nd edit:
Oh and now each time I boot it does the weird beep to say "I'm resetting everything" - what is going wrong, all of this just for an update... really guys....

3rd edit:
com port is showing, shit:

dynek · Thu Jan 22, 2015 12:55 am

Try Netinstall to recovery device firmware.

I have netinstall working with wine on OS X. Great stuff.
However, even selecting "Apply default config" doesn't give me 192.168.88.1 on ether1.
And the RB450G still makes this "I am resetting everything" sound each time I put power.

dynek · Thu Jan 22, 2015 2:17 am

OK so if that's of interested for you guys @ Mikrotik, I flashed back 6.19 and the router started working again. What a waste of time.

Any explanation as to why 6.19 -> 6.25 breaks everything ?

Finally I flashed each version from 6.20 to 6.25 and it worked. Also I first did a /system routerboard upgrade cause it was running 3.10 and 3.18 was there to be flashed.

Thu Jan 22, 2015 8:37 am

Did you connect by mac address to proove what is wrong? Or how did you "try to set ip manually"?

Thu Jan 22, 2015 8:40 am

Do you have DHCP client on bridge? If so, it might loose administrative mac address so then it could be impossible to get ip from DHCP server, as I realised by update from 6.24 to 6.25.

I can also confirm issue with windows 8.1 sstp vpn clients following upgrade to 6.25. Error 619 reported by windows vpn client when trying to connect.

Immediate downgrade back to 6.24 solved the issue. Windows 7 and server 2008 sstp clients unaffected.

This was on a CCR with Valid Wildcard SSL Certs.

So can I. (comfirm this issue)
Now All I can do is just downgrade the firmware of my RB750GL to 6.24, and it works well as usual.
I checked the log. There is no record about SSTP login.
The client (Windows 8.1) just shows error message "Error 619'

after upgrading to 6.25 on my ccr1016-12g we are seeing higher cpu usage and lower bandwidth consumption.
we have simple queues, dhcp and pppoe running and dns cache. cpu usage hitting 85 to 90%
bandwidth consumption dropped from 700mbps to ~550mbps on the same config as before

has some config changed somewhere that i should look into?
we have 3 mangle rules and about 10 nat rules. firewall only has drop rules and thats about 8 of them.
i'd gladly provide more info when required.

thank you

Major bug!

It is not possible to upgrade devices using "The Dude", we manage all our network through "The Dude", how come ?

Please explain why this now happened and when we can expect it work again ?

Without having the dude doing upgrade work, we are almost dead in water, it will take us forever to sit manually and upgrade devices one by one, we are back to very basic home user type of upgrading like in old days when we had only 3-4 routers out there.

Please come back with a solution on this quickly.....

Thank you very much for your reports and help. At the moment there have been fixes introduced to 6.26rc version, that is available from our download page.

Note the latest rc contains improvements for queues on CCR boards, those who have queues on CCR and testing rc version. We will wait for your feedback on this.

Sergejs can you check this example :

/ip firewall layer7-protocol
add name=tftp regexp="^(\\x01|\\x02)[ -~]*(netascii|octet|mail)"

/ip firewall mangle
add action=mark-packet chain=prerouting comment=\
    "FTP - File Transfer Protocol " dst-address=!192.168.11.200 in-interface=\
    public layer7-protocol=ftp new-packet-mark=qos-5_in-wan1 passthrough=no
add action=mark-packet chain=postrouting dst-address=!192.168.11.200 \
    layer7-protocol=ftp new-packet-mark=qos-5_out-wan1 out-interface=public \
    passthrough=no

/queue tree
add name=WAN1_IN parent=global priority=1 queue=default
add limit-at=1M max-limit=12M name=qos-5_in packet-mark=qos-5_in-wan1 parent=\
    WAN1_IN priority=5 queue=default
add name=WAN1_OUT parent=global priority=1 queue=default
add limit-at=100k max-limit=1M name=qos-5_out packet-mark=qos-5_out-wan1 \
    parent=WAN1_OUT priority=5 queue=default

Explanations:
I trying to setup qos but some thing dont work.
My ftp server (192.168.11.200) is in my public zone and have same gateway like mikrotik 192.168.11.1
Im try to exclude my ftp server from bandwith limit for users behind mikrotik ... which is visible in ip firewall mangle rule , but this is not working ... is this some bug or just im doing something wrong ?
Thanks!

Mon Jan 26, 2015 1:18 pm

This does not have too much relation to the specific version.
I assume it is much better to use port and src/dst-addresses to filter FTP traffic, instead of layer7 rules.

Tested 6.25.
On SXT G-5HPacD works incorrectly automatic start configuration file after the reset configuration. If a file .rsc contains any mention of the wlan interface - configuration is interrupted at the location in the file where it is mentioned about it. If you remove from the file rsc any mention of the wireless interface - configuration updates correctly.
Also on SXT G-5HPacD still does not work tab «Current TX Power» on the wlan interface and don't work spectral scan.

spectral scan/ history doesn't work yet on wireless-fp driver (used by AC).

Are you using these units in a PTP? Any advised ROS version / Wireless settings (If I recall correctly nstreme wasn't useable yet) for a reliable PTP Link with STX AC units?

On ppp server (pptp) using torrent tumbled session (lost pumping).

routeros-mipsbe-6.26rc20 - SSTP client Windows 8.1 update 1 - works OK.

Is there an answer yet to not being able to upgrade units from Dude? Upgrading will be a long painful task without being able to do it from dude now.

I use a script via CRON to periodically SSH into a bunch of MikroTik devices and do "/export compact" to archive device configurations. When there's a change, it email's me the diff.

PROBLEM:
One RB433AH device running RouterOS v6.25 serving DHCP on a LAN (ethernet port) to a group of users keeps reporting configuration changes (via my "/export compact" configuration diff-generator script). First I'll see this as the only change:

-add address=192.168.88.9 always-broadcast=yes comment="Device 7" \
-    mac-address=06:17:F6:E6:DA:41 server=lan_dhcp
+add address=192.168.88.9 comment="Device 7" mac-address=06:17:F6:E6:DA:41 \
+    server=lan_dhcp

Then anywhere from an hour to several hours later:

-add address=192.168.88.9 comment="Device 7" mac-address=06:17:F6:E6:DA:41\
-    server=lan_dhcp
+add address=192.168.88.9 always-broadcast=yes comment="Device 7" \
+    mac-address=06:17:F6:E6:DA:41 server=lan_dhcp

THEN this cycle will repeat again in some random short time period. This will happen 6-12 or so times in each 24-hour period.

Note the ONLY change is the appearance and disappearance of this parameter: always-broadcast=yes

No humans are logging in nor making changes via any mechanism. Therefore it MUST be the device's own behavior changing the configuration spontaneously, possibly in response or triggered by one or more DHCP clients' requests.

OBVIOUSLY THIS IS A BUG - I mean a device should ALWAYS retain a configuration that is identical without some administrative intervention UNLESS there is some WELL-DOCUMENTED feature that automatically changes device configuration in response to network events. In this instance, I see no such documented feature anywhere.

I don't know how to reproduce this bug, however.

ANY SUGGESTIONS?

Thanks!
