Telnet App for Mac

Hello All, 

 

I was wondering what is the best telnet app for Mac (I am running High Sierra) to use to access Aruba switches? I am trying to use Telnet Lite, but it disconnects much too often. 

 

Thanks!!!

I simply use the built in terminal app.  It might be that the mgmt timeout on the switch is set to a low rate.  Check your switch's running config for loginsession timeout.

Rob,

 

Thanks for the reply, but when I try to access the terminal on the switch, I get this message. I don't see anything about being about to connect.

 

Note:
 Please refresh the page to re-connect
 Public key authentication is not supported
 For security purposes, the user needs to re-enter the password

Re: Telnet App for Mac

check /etc/sshd_config

what's the setting for PasswordAuthentication?

mine shows:

PasswordAuthentication yes

 

if you're trying to use pubkeys, you need to check /home/<user>/.ssh/authorized_keys and known_hosts files

if the switch is already in the list, try removing it in case the switch's pubkey changed.

I use iTerm2, and never ever use telnet anymore but Secure Shell (SSH) instead.

 

Try to get away from telnet, as usernames, passwords, configuration are transferred unencrypted. You don't want your switch password being sniffed, or even the config being seen.
