v7.4 [stable] is released!

[joaopedroalbernaz]

It bricked my 951ui-2hnd. The router seems to be working fine but when I connect via WinBox I get only blank screens (For example if I go to interfaces it doesn’t show any interfaces). and WinBox drops me every 20 seconds. Totally not “STABLE”

[pe1chl]

But what about other ftp client that connect without issue? This problem appeared after upgrade to version 7.3.1

Please paste exactly what a commandline ftp client shows when you logon to that server.

[pe1chl]

Every upgrade went well from 7.1.0 through 7.1.5 and I just can’t seem to get it to reliably play ball beyond it, I also lose logging to syslog hosts when upgrading, even though the host is configured and I can SSH from said host to the router.

Thoughts?

When you have it running in a 7.x release, do a /export show-sensitive file=name and download the .rsc file. Also make a .backup file just in case.
Then netinstall version 7.4. connect from winbox via MAC address, upload the .rsc file and reset the config to completely blank (no defaults) and /import the .rsc file with option verbose
Should it stop halfway, use the command again with option from-line to start past the offending line.
When finished, make a new /export and use a text compare tool to compare the files to see if you did not miss something.

Maybe you should clear WinBox session in WinBox folder as it could be WinBox problem, not 7.4 upgrade.

this does NOT work any more
why change something which worked before ???

how to match UEFI from now ?

[npeca75]

as MT DEVs could see

UEFI client asked for IP and totally wrong answer came from MKT
lpxelinux.0 instead of grubnetx64.efi.signed

clearly, Class-Id = “PXEClient:Arch:00007:UNDI:003000” does not match in DHCP server

bravo !!!

Upgraded my RB5009 from 7.2.3 to 7.4 and looks like it’s bricked. Can’t even get it to show up in Netinstall.

Have you ever netinstalled the device before, or is it the first try?
I’ve searched the forum for “rb5009” netinstall.

So:

1. I used a switch to connect RB5009. I used ETH1 as port.
2. I set the address for BOOTP server (setting in netinstall) to 192.168.88.199
3. On the windows machine, i set the IP to 192.168.88.2
4. Open windows firewall ( windows asked me to do that)

http://forum.mikrotik.com/t/bricked-rb5009-trying-7-1rc6/153245/1

Yes, I have. But what I’ve observed in the past, is that the RB5009 (or RB4011, my previous) would show certain activity via the LEDs when powered on, and getting into Netboot via the RESET button, the activity changes.
My RB5009 simply powers on, shows the Blue LED, and the Eth2 LED (faintly), and nothing changes. This is whether powered on “normally”, powered on with RESET held, or holding RESET immediately after power on.

I believe I’ve seen posts online saying that the faint LED on Eth2 is more than likely an indicator of a hardware failure.

[osc86]

if it looks like that, it’s probably dead. I had to rma my RB5009, just 4 days after I got it. Died during fw update.

[Zacharias]

@osc86 how about trying to netinstall the device ?

Updated without incident the following router:

When that " The local time is" line indeed has a CR/LF in front of it, this certainlu is a fault of the FTP server!
There should be “230-” in front of that line, just like the “230-Welcome user” line.
So try to find why it outputs that line and how it can be removed or corrected.

Why did it not fail in previous RouterOS? Likely, someone reported that the FTP client did not handle errors properly,
e.g. when the user/password was refused it would not notice that, and now the FTP client does proper parsing of those
3-digit numbers on each line (which are error/status codes). It now fails because your FTP server sends garbage.

Thank you BartoszP, I have tried it but unfortunately did not help, also tried getting the latest WinBox off MT’s website. I did figure that login via MAC locally works fine but login via IP is having the disconnection problem every 20 seconds. Strange is, the connection via IP has been working for the last 3 years without any issues and just now got bricked with the 7.4 release

[osc86]

@Zacharias netinstall didn’t work. RMA center confirmed that the device is broken.

That’s exactly what mine looks like.

I don’t think that’s right:

@https://datatracker.ietf.org/doc/html/rfc959

Thus the format for multi-line replies is that the first line will begin with the exact required reply code, followed immediately by a Hyphen, “-” (also known as Minus), followed by text. The last line will begin with the same code, followed immediately by Space , optionally some text, and the Telnet end-of-line code.

For example:

123-First line
Second line
234 A line beginning with numbers (<-- quote ate the space at the beginning of this line)
123 The last line

The user-process then simply needs to search for the second occurrence of the same reply code, followed by (Space), at the beginning of a line, and ignore all intermediary lines. If an intermediary line begins with a 3-digit number, the Server must pad the front to avoid confusion.

[pe1chl]

Ok I apparently assumed to easily that the line format for FTP would be the same as for SMTP, where certainly it is as I described.
I seem to remember that FTP servers sending large banners always formatted them with those continuation reply codes in front of every line, but maybe that was just the safest thing to do.
At the moment, it is difficult to confirm that as FTP has been phased out by most sites by now.

Edit: this is what I meant:

Connected to ftp.nluug.nl.
220-Welcome to the FTP archive of 
220-The Netherlands Unix Users Group (NLUUG).
220-
220-This server is located in The Netherlands, Europe.
220-If you are abroad, please find an ftp site near you.
220-Most information on this site is mirrored.

220-If you don't like this, disconnect now.

220-Problems?  Mail ftp-admin @ nluug.nl
220-
220-You may login as "ftp" or "anonymous".

But then indeed it appears that the changes in v7.4 do not conform to the RFC959 standard and need more work to handle the format as described in the RFC.
Well, well…

For obscurus: note that likely nothing further will happen unless you make a ticket about this (either by mailing it or by directly creating the ticket in the support system). Bugs reported in the release topics are usually not picked up by MikroTik staff, unless a developer of a particular piece of code sees it and creates the ticket himself.

[dalami]

I have a pair of hAP lites that I upgraded to 7.2rc4 a few months ago - I don’t remember using Netinstall but maybe I just suppressed the memory. I just purchased another one, running 6.47.9, and it appears there isn’t enough free disk space to upload the package via Winbox. The /files area is empty - but I don’t have 8M available. Is the only upgrade option a Netinstall?

[Tporlapt]

The problem with Simple Queues with cake (only cake) locking the router so far appears to be fixed in 7.4

[nichky]

can anyone confirm whether vpn 4 works on v7?
i got feeling that Mikrotik is hidesign that info,correct me if i’m wrong
