Hi all,

I'm trying to login to an EX 2200 via console and i have the correct credentials. 

It appears to accept the login and kick me straight out. 

As you can see below - the password is accepted (it doesnt say Login incorrect)

Telecity-ex2200-T (ttyu0)

login: root
Password:

Telecity-ex2200-T (ttyu0)

login:

Any ideas what causes this? 

I think it maybe related to retry options, however I didnt think this affected console login attempts. 

Thanks

Chris

Hi there,

Do you have this line in the config:

set system ports console insecure 

 If yes then direct root login is not allowed, you have to login as any non-root user and then do:

start shell user root
<give password>
cli

 HTH

Thanks

Hi Alex,

Thanks for the reply.

Forgot to mention the exact same thing happens on a non-root user too.

It accepts the login then kicks you out.

I suppose it's a symptom of the command:

set system ports console disable, right?

Thanks

Chris

That sounds like what would happen if there was another console login elsewhere. Try ssh or telnet via another user then show system users to see if multiple users are loged in and if the console port is also logged into.

Hey guys,

I've kinda resolved this now. Just in case anyone else has the problem.

I booted into single user mode during some scheduled downtime, I was able to grab some logs and change config etc.

Upon a normal reboot, the issue reoccured.

Looks like there's some corruption somewhere. 

JTAC recommend a fresh install.

Regards

Chris
