Question 1

How do I install i2cssh on my Mac?

Accepted Answer

Install via Homebrew: `brew install wouterdebie/repo/i2cssh`. Then, enable the Python API in iTerm2 under Preferences -> General -> Magic to allow the tool to interact with iTerm2 properly.

Question 2

i2cssh or csshX: which should I use for multi-SSH?

Accepted Answer

i2cssh is better if you use iTerm2 on macOS, as it integrates natively with split panes and is faster due to the Python API. csshX is more cross-platform but relies on older methods like separate windows and AppleScript.

Question 3

How to send a command to all servers in i2cssh?

Accepted Answer

After sessions are open, use iTerm2's built-in feature by pressing ⌘-shift-I to enable broadcast input. You can also start with broadcast enabled using the -b flag in i2cssh or set it in the config file.

Question 4

Can I use i2cssh with Kubernetes pods?

Accepted Answer

Yes, via the -x option for custom commands, such as `-x "kubectl exec -it {host} -- /bin/bash"`, allowing you to manage Kubernetes pods similarly to SSH sessions, as mentioned in the SSH options.

Question 5

What's the difference between -t and -T options in i2cssh?

Accepted Answer

-t groups hosts into one tab per argument group, while -T puts each host in a separate tab without grouping. This affects tab organization for better management of multiple clusters or hosts.

Question 6

i2cssh configuration file example for multiple clusters.

Accepted Answer

Create a YAML file at ~/.i2csshrc with clusters defined; e.g., specify hosts, optional parameters like login and profile, and use include_from for reuse. Refer to the README for syntax details and precedence rules.
