Cannot SSH into openwrt on new install

Installing and Using OpenWrt
1

Just installed OpenWrt 19.07.3 r11063-85e04e9f46 / LuCI openwrt-19.07 branch git-20.229.71287-57456a7 on my TP-Link Archer A7 v5. I have access to LuCI however I have no ability to SSH. I have enabled SSH access in the Administration section and I can reach the router from my machine, however I am getting issues with ash and it looks like ash cannot find a program called tic. I do not know if telnet is disabled by default but I cannot telnet into the machine either.

✗ ssh root@192.168.1.1

The syslog shows:

@pard, welcome to the community!

What other changes did you make to the OpenWrt?

SSH to the router from LAN is enabled by default on a fresh OpenWrt install Also, there's no password by default. So your issue is very unclear.

That's normal.

This is what I did, wasn't aware that SSH was enabled by default, I've always done this as my first step :smiley:

Ummmm...your response didn't help, not did it answer all inquires. All I can suggest is to reset OpenWrt to defaults and try again.

I think I've previously had issues trying to specify an interface for SSH (particularly to a bridged VLAN); but I cannot find the thread at this time. Nonetheless, the firewall only permits input to the router (including SSH) - from LAN by default. I suggest leaving it set to "unspecified".

:warning: You will need to remove the old SSH key from the client when you reset the router - you can safely ignore the security warning, follow its instruction to remove the old key and re-consent yes to the new key.

Sorry my post wasn't clear, the only thing I did was go into Admin -> SSH and change the settings shown.

I just reset my openwrt and...

❯ ssh root@192.168.1.1

So the same thing, must be an issue with the image I guess.

Reset/fix your SSH configuration and/or shell profile.

Download a fresh copy of Putty and ssh to the device.

That did it. I must have security requirements in place that busybox/dropbear is unable to fulfill. This did the trick, thanks.
