Log File#

Once you've started using Sauce Connect, a log file will populate in your computer's directory. The log file name depends on whether --tunnel-name was used.

For anonymous tunnels, a log file name would be sc.log, for named tunnels, a log file name would be sc-TUNNEL_NAME.log

The location of the log file will vary, depending on your operating system. For Mac and Linux, the sc.log will use a tmp folder. For Windows, it'll use the current working directory.
