I've just completed updating to High Sierra. I've also successfully installed GNS3 (Network Simulator for Cisco studies) on High Sierra. I get the following message in the console while trying to access the CLI for the network devices with iTerm. 

sh-3.2$ exec telnet 192.168.56.101 5000
sh: exec: telnet: not found

The following message shows up when I try and use Terminal.

-bash: telnet: command not found
logout
Saving session...
...copying shared history...
...saving history...truncating history files...
...completed.

[Process completed]

Any help would be appreciated.

  • Thanks Tetsujin. The reply to that post asks for compiling yourself. I have no idea how to do that. – user257093 Sep 26 '17 at 08:51
  • The second part says it's available ready-packaged from homebrew. Either way, it's gone from native macOS since HS. – Tetsujin Sep 26 '17 at 08:53
  • Thank you Tetsujin. I've done what you suggested. I'm able to now access the CLI using Terminal. However I still get this message while trying to access the router CLI with Iterm. Any idea what I should be doing to get it working in Iterm?

    sh-3.2$ exec telnet 192.168.56.101 5000 sh: exec: telnet: not found sh-3.2$

  • So If I go into the bash and try and telnet, it works.

    MacBook-Pro:~ RP$ telnet 192.168.56.101 5000 Trying 192.168.56.101... Connected to 192.168.56.101. Escape character is '^]'.

    IOU1# IOU1# IOU1#

    However, when I click router icon to bring up the CLI in iterm, the prompt is a non root shell.

    sh-3.2$ exec telnet 192.168.56.101 5001 sh: exec: telnet: not found sh-3.2$

    I wonder if the prompt not being root shell could be causing the issue?

  • If you installed telnet with Homebrew and it is working from the prompt but not from your tool, I would guess some path issue. Try getting the path for telnet by executing which telnet from the prompt and using the full path in your tool, instead of only telnet. – lpacheco Sep 27 '17 at 05:03
  • Thanks Ipacheco!

    This is what I get when I type in which telnet in terminal

    "/usr/local/bin/telnet"

    I cannot find any option in the preferences for iTerm that can be used to specify the above path. What command should I run in iTerm to change the path to "/usr/local/bin/telnet"?

  • NVM! I got it. Thank you! Had to make the change in GNS3. – user257093 Sep 27 '17 at 08:28
