Modify ProxyCommand to no longer use NetCat for proxied access to tester host #19

Closed mlaruskiaws closed 1 year ago

mlaruskiaws commented 2 years ago

Instructions in README.md require use of NetCat with ProxyCommand ("ProxyCommand ssh bastion nc %h %p") this no longer works on the bastion host and results in an error.

[bash: nc  : command not found kex_exchange_identification: Connection closed by remote host]

Instead, use the -W switch with OpenSSH ("ProxyCommand ssh -W %h:%p bastion").
