Will there be any solution to the abovementioned diskspace problem on the CCR?
For now I have rolled back to 6.42.1 but will that even solve it in the future?
Or is this installation doomed when no netinstall is done?

The problem is being solved, but definitely it will be solved not in current versions :)

I know that this kind of problem is often caused by the version you are running now, that does the update to the next version.
What I need to know is if there will be a next version that has fixes to undo the problem caused during the update (e.g. delete leftover files).

I find it puzzling that a "check installation" merely returns OK but does not free the space (when doing it in 6.42.3 after the update from 6.42.1).
I think it was announced before that such checks would also check for and remove unexpected files, and that should indeed be possible
as the packages would typically include a list of files and checksums. Apparently "check installation" now still only checks for expected
files and does not find (let alone remove) extra files. What does that mean for its capability to detect worms?

Remember this problem PREVENTS further updates. So when there is to be a workaround, it has to be made available (as a small package)
for current versions or it will be useless. (as it would require a netinstall)
As has been shown by CHR users, it would be probably quite easy to fix when there would be shell access. But even without that, a
simple package that only applies the fix should be easy.

We were trying to establish ptp link of around 80Km with netmetals. Our configuration was cell radius set to 100Km and tdma size to auto. With tdma size auto we can scan and see the other side but we cant connect. After long troubleshooting we decided to change tdma size to 6ms and the link connected and throughput was very good around 90-100Mbps at 20Mhz channel beating other link from another manufacturer which was in operation

the os installed is 6..42.3 so am not sure if this is the bug or by design tdma size set auto will not work with very long links. We have other links of around 40km and tmda set to auto works well. Only we had issue with this 80km link. I have not tested this behaviour with previous os because this link is new and radios had this version installed

There is some issue with firewall rules or maybe they work differently now.I think it started with 42.2 version.
My ICMP rules made on input and/or forward chains are ignored.
They were working just fine in 42.1.
I usually drop ICMP Type 8 Echo Request when i am not playing online games from WAN (BF4 for example requires it otherwise you get kicked).
When this rule was enforced no ping could be seen in BF4 players list , now the ping shows up with the exact same rules :).So what s the problem ?
Why is ICMP going thru even when no rule is allowing it ? :)
Has something changed in relation to firewall rules since 42.2 ?
I have downgraded to 6.42.1 and the ICMP rules on the input chain are picking up traffic again and loging it.So in the 42.3 a simple rule that logs ICMP would not do anything while a ICMP rule on the forward chain would not pick up all ICMP traffic.On 6.42.1 the things seem to be working properly ,same firewall ruleset made from within the winbox interface keep in mind.
It s like ICMP would go around the firewall in 42.3 ,on it s own:)
Try on my CCR1009, with 6.42.3 drop ICMP type 8 working correctly, it also work in raw(prerouting)

Hi all,
I have successfullty set up Mikrotik WAP LTE Kit to work with LTE Provider. Everything works fine, except firmware upgrade process.
I have current firmware 6.42.2 installed. Avaliable firmware for my RouterBOARD wAP R-2nD is 6.42.3.
When I download this firmware and reboot router nothing changes (6.42.2 remains as current firmware). I've tried to use "Download and Install" button and drag'n'drop firmware file to files window. Both approaches does not appty firmware upgrade after reboot.
Also when I schedule to uninstall extra package (for example NTP package) it remains after reboot despite "scheduled to uninstall" status.

System resources:
Memory - 37.5Mb free (out of 64mb)
Free HDD space - 4.5mb free (out of 16Mb)

Log right before and after reboot shows nothing interesting:

I updated all the routers under my control from 6.41.4 to 6.42.3.. The only issues were that i needed to go thru my scripts and make sure they only had read/write/test/reboot and I needed a new Winbox. I used the Winbox "check for updates" and this worked perfectly. I updated CCRs, MIPSBEs like 2011's, a PPC and even a mAP. For my use I know of no issues.

6.42.x breaks sometching quite badly in DHCP server.

I have a setup where a CCR1016 serves several VLANs, with a dedicated DHCP server to each VLAN.

6.41.4 works beautifully without any sort of hiccups.

6.42.x sometimes won't bring the DHCP instances up in the first boot.
If i reboot the CCR, then sometimes the system brings part of the DHCP servers up.
Sometimes all DHCP servers will be up at boot time, but an hour or so later customers start calling and... AHA! --All DHCP servers are RED again :headbang:

i had this happen in two different CCR1016's, they have twin configurations, altough the only unnusual condition in these is the sheer number of DHCP instances(600 and 1200) respectivelly.

I recon you have your reasons!? But to me it sounds like bad design, burdening down the router with 1200 instances of DHCP servers. One server could off course serve many more scopes or you perhaps should rethink your DHCP strategy and relay requests a couple of hops away into a redundant DHCPServer setup else where in your net....
I'm in no position to point fingers, just my thinking when reading your post.

PS. From MT's side of things if RouterOS lets you do the configuration it should work or you shouldn't be able to create more than the OS can handle. But that's another discussion I'm afraid. DS.

I had issue with RB3011UiAS, with USB3 port. After upgrade to 6.42.3 USB ports does not recognized USB Flash memory at all (Kingston Data travellers, one USB2, one USB3, tried one other USB3 too), nothing in section system / Disks. Did downgrade to 6.42.2, USB2 started to appear as before, USB3 still not recognized, same as previous versions - never had working usb3 on this board.

Hello Folks!

Unfortunately the WIFI (802.11N in this case) problems remains in this version.

Connecting to WiFI and Loading the router with some wifi traffic causes CPU go sky high 100% at all time, and traffic goes down from normal 20-30Mbit/s to 0.5Mbit/s and starts to interrupt all the time. Ultimately the router crashes after some time.

An attempt to downgrade to 6.41.3 lead to)
RouterBOOT booter 6.42.3

RouterBoard 411

CPU frequency: 300 MHz
Memory size: 32 MiB
NAND size: 64 MiB

Press any key within 2 seconds to enter setup..

Too many levels of symbolic links

Then the device just sits there forever, next will now be a try using netinstall.

Hello.
In mitigating VPNFilter, I have started upgrading, but now have stopped. I have bricked 3 RB750GL routers.

First one I thought it was my error for not getting all the add on packages. Just downloaded routeros-mipsbe-6.42.3.npk which states it is for RBxxx. Placed file in FILES and rebooted router, it went away and never returned. It is remote, so I have no clue.

Second try, I did the same thing, except also downloaded packages I knew I was running, (seen in PACKAGES) so this router received:
advanced-tools-6.42.3-mipsbe.npk
dhcp-6.42.3-mipsbe.npk
hotspot-6.42.3-mipsbe.npk
mpls-6.42.3-mipsbe.npk
ppp-6.42.3-mipsbe.npk
routeros-mipsbe-6.42.3.npk
routing-6.42.3-mipsbe.npk
security-6.42.3-mipsbe.npk
system-6.42.3-mipsbe.npk
All uploaded to FILES and I rebooted the router. This router rebooted, I was able to logon, I was able to pull up a console and see that it did upgrade from 5.4 to 6.42.3. It ran for about 2 minutes, I was moving on to the next one and my network started acting funky, dropped packets, remote desktops dropping connections. I went back and could not WinBox back into this router. I went to the closet and the router was acting really funky with crazy LED activity on the switch side. I shutdown the router and the network issues cleared up, removed the router to isolate it with just my notebook. It now boots, flashes all 1-5 led's for a split second, then out. A few seconds later all lights then nothing. Activity light on side is also flashing, doesn't seem to be any pattern with either. The router is a brick, not responding to any commands.

Afraid to move on at this point. I have 4 more RB750 HEX lites and a RB750 HEX v3.

Is it that 6.42.3 won't work on RB750GL's?
Is it that I could already have been infected with VPNFilter?

Anyone have suggestions?

.
That's a very large jump in software. I recall 6.29 was a robust early version that might be worth using as an intermediate stepping version. From your brief summary it appears you haven't upgraded to the latest firmware, ( \system\routerboard ) you need to do this with each upgrade.
With your current situation I'd try a Netinstall with your laptop and router both connected to a dumb switch and no other devices.

Unfortunately netinstall did not work either, yet the device appairs in netinstall and you can begin an "install", but the completeness bar does not move and after some time the device goes goes back in ready.

I have had this same issue in the past with 411 boards. But since I removed almost all 4xx, and 7xx boards from my system I don't have that issue. I think these 'old' boards are just not good enough anymore to run the latest ROS. No matter what they say about compatibility. I would start replacing these board for more modern (and thus faster) units and that way also stay out of these issues....
To give you some hope, I'd remember that some boards needed several attempts before they finally took the netinstall upgrade. And do the system package only. Needs less memory.
I had the feeling at those days it was more a memory issue with bad sectors after so many read/writes over the years so the new packages simply couldn't installed properly.

I had the feeling at those days it was more a memory issue with bad sectors after so many read/writes over the years so the new packages simply couldn't installed properly.
Indeed they are aged, we have many of them still in production, we replace them when they fail or when customer experience some issues. But it does not happen to often I must say, so we still need our old RB411 devices. We actually freezed upgrading them some time ago, disabling but not uninstall all unneeded packages and so on to minimize the resource usage.
I think the device in question have problem with ether1, several other RB411 upgraded worked and did not show any signs of problems, but we followed a stepwise upgrade in some cases via latest bug fix. However WiFi 801.11N did not work properly in this release, at least not using RB411 so we are stuck at 6.41.2 and 6.41.3 and I should have stayed on bug fix only on them I guess.

But to me it sounds like bad design, burdening down the router with 1200 instances of DHCP servers.
This approach was actually presented on recent MUM Melbourne where local ISP Tasmanet solved need to do DHCP with static reservations per each customer. They ended up with ton of /32 DHCP servers which each serve exactly one customer. If customer switch their router (come up with different MAC), DHCP will not get confused and customer will get same IP.

Is it that 6.42.3 won't work on RB750GL's?
Is it that I could already have been infected with VPNFilter?

Anyone have suggestions?
.
That's a very large jump in software. I recall 6.29 was a robust early version that might be worth using as an intermediate stepping version. From your brief summary it appears you haven't upgraded to the latest firmware, ( \system\routerboard ) you need to do this with each upgrade.
With your current situation I'd try a Netinstall with your laptop and router both connected to a dumb switch and no other devices.
You are correct, very large jump. Maybe that was it. Maybe I was already infected. Weekend of playing, luckily I had an older 750GL I could use offline to restore my old configs from backups. (I won't use this method again) so that I could export to a file the configuration script. Then I was able to bare metal the bricked 750GLs by using NetInstall and 15 second reset to put them in NetInstall mode. I loaded the new v6.42.3 and manually worked on importing the saved scripts on each. Modifying things that have changed since the old v5 versions of RouterOS.

I did finally get them up again and seem to be functioning just fine. I still did not update firmware, as 1.) the official statement said it did not effect firmware, just RouterOS. 2.) I was already nervous about the whole netinstall (never done that before) and permanently bricking the devices. ;-|

Virtual AP seems to be broken in 6.42.3, I upgraded an AP and a CPE and they did not reconnect. AP shows authentification errors. Moved the config of the virtual AP Interface to the main interface and connection comes up. Protocol is 802.11/WPA2 PSK. Updating the CPE was not the problem. As soon as the AP is upgraded problem started.

Re: v6.42.3 [current]

I just ran into this problem adding virtual interfaces in caps man. Fix for me was to manually change all the virtual mac addresses to unique ones.
Virtual AP seems to be broken in 6.42.3, I upgraded an AP and a CPE and they did not reconnect. AP shows authentification errors. Moved the config of the virtual AP Interface to the main interface and connection comes up. Protocol is 802.11/WPA2 PSK. Updating the CPE was not the problem. As soon as the AP is upgraded problem started.

Re: v6.42.3 [current]

Current version has an important memory leakage.

On my two CRS109-8G-1S-2HnD with 6.42.3 (stable) I am experiencing a continous memory leakage, which leads eventually and invariably in an unusable system.
The device boots-up using 32 MB of RAM, and after five to six days ends up using 128 MB (on board maximum available). When the memory is exhausted static routing and bridging work, but all other services (DHCP, DNS) fail. In this situation it is difficult or impossible to even log into the devices.

Trying to downgrade by just pushing the button on System Packages menu causes reboot but keeps the same version. Should I downgrade by manually downloading the previous packages?

Thank you and best regards,
AV

Current version has an important memory leakage.
Are you certain that you do not have some feature which would consume lot of ram? Logs, packet sniffer, http proxy etc... ? Even if you did not set it up manually, check these things.
If memory leakage is real, then it is definitely worth of sending supout.rif to support@mikrotik.com once you reach some significant usage (100MB etc..). Only they can try to identify the issue behind this. (shouldn't be actually that hard - I am pretty sure there will be list of processes and their allocated memory.)

FW: 6.42.3 (stable) If my Mikrotik router(RB433L) is configured in native Ipv6 mode(without IPV4 address) i cant get package update from mikrotik CDN.
It seems that Mikrotik does not receive AAAA from my DNS, but if I make a request through DIG - my DNS gives AAAA
[romas@ns0 unbound]# dig mikrotik.com AAAA
I don't think it's 6.42.3 specific or a new issue. Perhaps new dedicated thread or feature request could be good.
Management plane implementation on MT routers does not follow RFC6540, this was discussed earlier in MT forum. I would expect any IP-router sold after 2012 support IPv6 in all planes. No full RFC6540 support should mean router is "IPv4 only device with random IPv6 functions". :)

While you can force certain management plane functions use AAAA information, it seems to me package update procedure is hardcoded to IPv4 addresses.
You can verify that creating static AAAA only entries (2a02:610:7501:4000::226 and 2a02:610:7501:1000::196) for download.mikrotik.com. Just flush DNS cache and try "/system package update check-for-updates" in some 10 minutes.
My test results are in attachment.

Update of rb2011 from 6.41.something lead to bootloop. Netinstall was needed. 493ah and rbd52g accepted this version without any problems.
