routeros 7.3.1 - ip ssh not working

OlofL · Fri Jun 10, 2022 5:18 pm

after upgrading to 7.3.1
ip ssh is not working...

I tried:
[*] change any options and press apply
[*] press "regenerate host key"
[*] import ssh pubkey to user
[*] upgrade to 7.4beta, downgrade again
[*] export ssh-host-key
[*] export host priv+pub files from another mikrotik and import to this one

I get these errors
Couldn't perform action - feature is not implemented (2)
or
error - contact MikroTik support and send a supout file (2)
or
#error exporting /ip/ssh

I am also seeing the same issue. Mine is a Hex Lite, RB 750r2. Also on 7.3.1.

Exporting the key gives the same error.

Also, no SSH access at this point.

I can confirm that this issue exists also with RBLtAP-2HnD (LtAP LTE6 kit) (mmips) and RouterOS 7.3.1

I just created support ticket (/w supout.rif, screenshots) from our testing unit.

Waiting for MikroTik support to respond.

Same for RB760iGS (hEX S) on 7.3 and 7.3.1 - raised a ticket 3 days ago but no success yet...

I seem to have the same problem on RB5009 and 7.3.1.

Brand new RB5009, came with 7.1.x, upgraded to 7.3.1, did most of the configuration in Wnbox and Wnbox Terminal. Only encountered this error when configuring /ip/ssh.

/ip/ssh print results in "error - contact MikroTik support and send a supout file (2)"

Found the problem. Here's how to replicate it.
(from "/system/reset-configuration no-defaults=yes")
1. /ip/ssh/set strong-crypto=yes
2. /ip/ssh/regenerate-host-key
3. reply n
(seems fine if Y to regenerate-host-key)

FYI

I've tested a debug/development firmware for mmips devices that fixes SSH service issues.

Mikrotik Support has informed me, that their proposed fix will be included in the upcoming releases:

Great, glad to hear that. We will finish up the fix and will include it in the upcoming RouterOS releases.

So, help is coming. We'll just have to wait a little while

soonwai · Thu Jun 16, 2022 11:26 am

^^^ Same here. Test version fixes the problem.

Mon Jun 20, 2022 2:05 pm

This problem should be resolved in v7.4beta4. Please test and see if the fix is working properly for you.

MIPSBE version was also affected. Upgrading to the now-current v7.4rc2 solved the problem.

MIPSBE version was also affected. Upgrading to the now-current v7.4rc2 solved the problem.

Since a few days ago, now current is 7.4 (release version).
