    How to fix ssh host key not a multiple of 256

    When using SecureCRT (version 9.2+), part of being FIPS compliant is that the ssh key of the host being connected to, must be a multiple of 256. To be clear, I'm refering to the HOST key on the router itself, not the key used by the client to connect. Out of the box default for Merlin is not the...

    SSH connection stops working after ~12h to Asus RT-AX86U -router

    SSH works as it should for approximately 12h which after the router gives me "kex_exchange_identification: read: Connection reset by peer". When I change any setting in the router via the WebGUI and press apply, SSH works again for 12h. The SSH timeout is set to 0 (disabled). There seems to be...

    reboot instead of halt when using putty

    Hi! When opening a command line / bash with WinSCP and typing in "halt" everything works like a charm: the router stops everything within 10-20 seconds and every LED is finally turned off and the router ready for poweroff. But when I try to achieve the same using Putty, the router always only...

I’ve been running Merlin 386.9 on my RT-AC86U since very shortly after the final version was released — my most stable experience in a long time!! No freezing. No lock files. No nothing. (Additionally, I run...

    Hello everyone, on an Asus Merlin router (I have RT-AC86U), is it possible to upload a saved file of router settings via command line, logged into the router via ssh?

    How do you "remote" edit files on your router in a GUI editor on your Mac/PC?

    So far I have been mainly using vi to edit files on my ASUS router (in an SSH session on the command line), but I would prefer a GUI editor (with syntax highlighting, etc.) on my Mac/PC. Visual Studio Code has support for remotely editing files over SSH, but I don't think my AC86U router...

    Sometimes it just much easier to access and modify some files via SSH. That's how I do on my OpenWRT devices. But on Merlin it is not clear for me where are the configurations stored. For example where can I find the Asus(?) MiniDLNA configuration file and where are the Entware related...
