ASUS RT-AC88U Telnet

[TheLyppardMan]

I have just taken delivery of an ASUS RT-AC88U router and have done most of the configuration. I haven't yet connected it to the Internet, but it seems to be functioning OK so far, using the latest Merlin build. The only strange thing I noticed was when adding devices to the wireless access controls list, the name/details I had assigned to the devices would all change back to "New Device" each time I hit the Apply button, but strangely, each time I added the next device and before I hit the Apply button, all the previous details I had entered returned, as they also did if I just moved away from the page and then back again.

Anyway, I digress - The query I have is how to switch on Telnet access, so that I can set up John's tool. I can't find it anywhere (I'm sure it used to be on the same page as SSH on my last router). Can anyone advice me how to do this please?

 - REMOVED: Telnet server.  Please use SSH for console-based
              management.

you can even easy use Win10-1803 integrated SSH-client, works for me, similar to telnet.
open powershell as admin: ssh your_router_user@10.0.0.1 (replace name and IP)
Sometimes I have to delete file \users\your_Win10_user\.ssh\known_hosts, dont know why but seems to need changed key inside.
First you have to enable SSH on router admin-page.

Just wondering then, how do I use John's tool using SSH as the only instructions I have refer to accessing it via Telnet?

Exactly the same way. They both support command-line terminal sessions. The only difference is the protocol used to send the data over the link (Telnet vs. SSH).

Yes, that is all I have ever used is SSH, and I did use John's tool extensively until the new software that it does NOT support. Be careful, some changes in NVRAM have made John's tool unusable for newer software. From what I understand there are potential issues with changes past version 380, so I have not used it on 382 or 384 firmware. Here is a link.

- As mentioned, the big problem in 380 -> 384 migration is the possibility of exceeding the new nvram length checks. This is something that can be handled, but it needs to be coded as well as adding the length info to the nvram ini file.

OK, thanks for this, but in view of what you say, I'll leave attempting to use John's tool until I know it won't cause problems. I hope it can be fixed because it was a very useful tool.

Just make your own script to set nvram settings the way you want them. It is what I did and only took an afternoon.

And holy crap. When anyone says telnet it makes me vomit a little.
