By default, Core Tunnel uses configuration files in its own container folder:
# known_hosts ~/Library/Group Containers/E78WKS7W4U.io.coressh.ssh/.ssh/known_hosts # ssh_config ~/Library/Group Containers/E78WKS7W4U.io.coressh.ssh/.ssh/config
This works very well in most of cases. But if you have a lengthy
/etc/ssh/ssh_config, or have StrictHostKeyChecking set to
yes and use
/etc/ssh/ssh_known_hosts as the only source data trusted host keys, you may want to use system default configuration files instead.
You just need a few steps to enable system default configuration files:
1. Change locations to System
- Open Preferences… window, then click Locations.
- Change Known Hosts and / or Configuration to System.
2. Install Helper Tool
Core Tunnel may prompts you install a Helper tool, click Visit Website… to download and install the tool.
Consult the discussion in this thread if you are curious why a Helper is required:
After install the Helper tool, reenable the options in 1st step again.
4. The End
Now Core Tunnel should read and use your configuration files in following sources:
- User’s configuration file (
- System-wide configuration file (
- Global host key database (
- User host key database (
