How to clear /.ssh/known_hosts for chrome extension.

[vps...@gmail.com]

Actually one of my server is formatted. After that server is not accessible from my chrome. Need to remove the entry from /.ssh/known_hosts. I am familiar with this but I am not getting the exact location of this file in my PC. I am using windows 7 professional. If it was Linux box then easily I can. Tell me where it is exactly located.

Thanks in advance.. :D

I have the same requiremtn but cannot find answer. could you share your answer ?

[jrpdu...@gmail.com]

From https://github.com/libapps/libapps-mirror/blob/master/nassh/doc/faq.txt#L460:

  If you know the index of the offending host entry (it's usually reported
  by ssh if the connection fails) you can open the JavaScript console and

  type...

     term_.command.removeKnownHostByIndex(index)


  Replace index with the numeric, one-based host index.



  If you don't know the index, or you'd like to clear all known hosts,

  type...

     term_.command.removeAllKnownHosts()

And how do you "Open the JavaScript console?"

Control-Shift-J (or on OS X, I think it is Command-Option-J)

[davecc...@gmail.com]

CTRL-SHIFT-I seemed to work for me (developer tools), then just choose the Console tab.

by the way, to use a command like:

term_.command.removeAllKnownHosts()

it must be done in the same browser window as the terminal is running in - it won't work in just any browser window (not global or whatever).

when done in the browser session i was having the key issue, it worked perfectly:

> term_.command.removeAllKnownHosts()

> true

and then i could connect, getting the authenticity prompt i was hoping for.

I have opened the terminal in the same window as the secure shell. When I run term_.command.removeAllKnownHosts() I get error:

VM300:1 Uncaught ReferenceError: term_ is not defined(…)

Sorry, what am I missing? This has worked in the past for me. 

[Robert Ginda]

The JS Console is associated with the window it was opened from, so you need to opened it from a Secure Shell window in order to see the Secure Shell term_ variable.

You need to initiate the connection and get the error message about hostkey. That is when you open the console and run the command. (If you open console from the connection selection screen it won't work)

Thanks for your help. Yes, this is exactly what I'm going. I wait until I get the error then I Ctrl + Shift + J to open up the console and still get Uncaught ReferenceError: term_ is not defined(…) error :-(

This is really frustrating, I really want to use SSH terminal but without anyway to clear the keys it's impractical since I develop using lots of different Raspberry Pi's on the  same network / IP

you don't need to connect.  simply load the console when at the connection screen.  i just tried it and it worked for me.

if term_ is undefined, try loading a second window, or refreshing the current one (ctrl+r).

For some reason I was getting "term_ is undefined" no matter what I tried, but when I went to the connection screen and did a ctrl-r I was suddenly able to access term_. Thanks!

[yeu...@gmail.com]

i have the exact same issue. this used to work for me but does not work anymore. super frustrating like you said!

[halto...@intel.com]

Same here, I'm not sure how many times open/close inspector, but finally term_ is there and I am able to remove know hosts.

[dcrobe...@gmail.com]

Hi - old thread, but if anyone else comes across it and is having problems - if you have set your SSH client to open in a window, you might not be able to open the Javascript console for that window. You need to right click the icon in the application launcher thingie and uncheck the 'Open as window' option. Then it will open in a browser window and give access to the console.

:-)

This is an old thread but I just noticed something new (to me)...

Right in the SSH app in Chrome, use Ctrl/Cmd + Right Click your mouse to a context menu. You will see several choices there, including one that will let you clear known hosts.

To be clear - that's CTRL on a Linux or Windows PC and CMD on a Mac.

Thanks!

Thank you!!!

[omka...@gmail.com]

Many Thanks!

[green...@gmail.com]

Wow, so simple. Thanks. Now I don't have to go into the Javascript interface.

[Marc Bernard Schauber]

Any update on this?  It no longer works... throwing the following error:

VM244:1 Uncaught ReferenceError: term_ is not defined

    at <anonymous>:1:1

[Pobega]

@Marc, the known hosts file is now exposed under 'Options -> SSH Files' on the left column.

[Marc Bernard Schauber]

Thank you.  It's nice to see it has been moved to an easy to edit location.
