I have the latest i2cssh installed

dmanna-a01:Downloads dmanna$ brew info i2cssh i2cssh: stable 1.3, HEAD https://github.com/djui/i2cssh /usr/local/Cellar/i2cssh/1.3 (5 files, 6.5KB) * Built from source on 2018-06-04 at 16:11:43 From: /usr/local/opt/i2cssh/.brew/i2cssh.rb ==> Options --HEAD Install HEAD version

But whenever I try to ssh to multiple machines like below:-

i2cssh -Xi=/tmp1/vnera-infra-ec2.pem -l support -b -d row -m ",,"

This does not seem to work and just opens the multiple terminals without the ssh prompt

enter image description here

The above command worked perfectly in Mac Sierra.


  • Iterm2 - 3.1.6
  • Mac OS - 10.13.4

Can someone let me know what is going wrong?

    Welcome to Ask Different. Can you ssh into one host? With or without the i2c prepended ?

    If I just do ssh support@ip it is working fine. The above i2cssh command used to work fine in Sierra.

    I was hoping to get you to simplify this like i2cssh -Xi=/tmp1/vnera-infra-ec2.pem -l support -b -d row -m "" but that's fine - it's your question to ask. You'lllikely be getting either a RTFM on debugging certificates and i2cssh or perhaps someone has a workaround that's undocumented or can point to the changes.
