Maglev cli

[KevinR99]

Hi

Has anything changed with DNAC and maglev commands?  I’ve not logged into the cli on our DNAC for some time and we have had several updates since.  We are at the latest version currently.  Yesterday I had an issue and wanted to run a tcpdump.  So I looked at my notes and got the commands

sudo tcpdump ……..

When I tried this it was an unrecognised command.  I’m certain I’ve run tcpdump before from the maglev cli.

Thanks, Kev

 - If possible search for the command with Linux find , it may not be included in the PATH of the current user.

This will be caused by the restricted shell feature that is enabled by default in the later versions of DNA Center 

When you SSH to maglev, you need to enter command '_shell' to enter the bash shell to be able to run commands such as tcpdump.

You can disable and re-enable the restricted shell feature if required

To disable

_shell -c 'sudo magctl ssh shell bash' 

To re-enable

_shell -c 'sudo magctl ssh shell magshell'

I was a little fast and typed only:
_shell

Now DNAC want to know the Challenge / Response Token. How can a clear that state?

$ _shell -c 'sudo magctl ssh shell magshell' 

A challenge is already in progress with state CT_STATE_RESP_WAIT

Please provide the consent token via [_shell -v] command for bash shell-access

Martin, you need to get onto TAC for a token.

Check the admin guide.

Hope that helps.

Regards.

Hey @Martin Grimm , i stumpled about the same issue. Were you able to solve it?

[Martin Grimm]

Hi Cedric, yes you need a TAC Case, for that.

[KevinR99]

Thank you.  That worked.
