CML 2.0 & Breakout tool won't display ports over telnet session using TERMIUS program

[Tony C.]

Hi there, this is more FYI.

I've faced a strange problem on my CML2.0 installation. I've it installed on a ESXi server version 6.5. 

I've spun up a lab with 6 IOSv nodes and use breakout tool to connect to devices via telnet since I run it on a remote server.

Although, if I run a "show run" command from the telnet session, the interfaces won't show up. But via the web console it will be fine.

I was connecting via OS X using a telnet client called "Termius" (available on windows as well).

Once I tried over a linux VM and the breakout tool it worked fine.

After installing telnet in OS X (Catalina, so I went via Homebrew) that was fine as well. Looks like this tool is not the best option for the Apple platform.

Looks like termius is cutting the configuration after the 1st page. Like you've pressed 'q' following show run, check the paging settings perhaps.

Thanks! You're right.

Termius sends an "^@" each time you type "enter" which breaks the text continuation. Same problem found on the windows version I just tested.

But this app terminal options are pretty much scarse compared to PuTTY or MobaXterm on Windows so I couldn't change any parameter related to that.

Anyhow I'll use telnet client from the OS X terminal. Just wanted a more friendly way to connect to my labs without having to type in each device ip/port and have them from a single tabbed telnet client app (and yes a shell script may be an option).

I have the same issue with royal TSX (had the same problem with terminus when trying to rule out royal TSX).  Oddly enough, if I add an external connector and enable telnet on the VTY ports, the issue disappears.  It seems to be specific to the breakout tool. Hopefully can find a resolution soon.
