Golang ssh tunnel8/14/2023 ![]() ![]() ![]() ![]() you go by train and have a high latency), you should choose a higher value for ServerAliveCountMax to allow ssh to keep trying to reestablish the connection. If you are more interested in keeping an already established connection (e.g.If you would like to quickly terminate the session as soon as the server does not respond anymore, you should choose a low value for ServerAliveCountMax.To make it persistent write it to /etc/ssh/ssh_config (will apply system-wide) or ~/.ssh/config (will apply user-only): ServerAliveInterval 60Īs dislick correctly pointed out, this might not what you want, depending on your situation: Therefore you should consider to set ssh -o "ServerAliveInterval 60" -o "ServerAliveCountMax 120" 2 hours of trying to keep the connection alive, you can do: The default value of ServerAliveCountMax is 3 (see manpage ssh_config).Įxample: If you set ServerAliveInterval to 60 and leave ServerAliveCountMax as it is, this means the keepalive will only wait for 3 * 60 = 180 seconds = 3 minutes before quiting. This will be done ServerAliveCountMax times if no response is received.The ServerAliveInterval will send a keepalive every x seconds (default is 0, which disables this feature if not set to something else).Defaults to the operating system username.In addition to Mike Pennington's answer, I would like to make you aware of ServerAliveCountMax too. Single executable including both client and server. Useful for auditing operations executed by 3rd party tools. Chisel is a fast TCP/UDP tunnel, transported over HTTP, secured via SSH. With port forwarding, the SSH client creates a secure encrypted tunnel between the client and the server, allowing traffic to be forwarded through the tunnel to access resources on the remote system. user string Specifies the user executing the operation. Port forwarding, also known as SSH tunneling, is a feature of SSH that allows users to securely access network services running on a remote system. stderrthreshold severity logs at or above this threshold go to stderr when writing to files and stderr (no effect when -logtostderr=true or -alsologtostderr=false) (default 2) skip_log_headers If true, avoid headers when opening log files (no effect when -logtostderr=true) you go by train and have a high latency), you should choose a higher value for. skip_headers If true, avoid header prefixes in the log messages sshtun is a Go package that provides a SSH tunnel with port forwarding supporting: TCP and unix socket connections Password authentication Un/encrypted key. If you are more interested in keeping an already established connection (e.g. skip-audit Skip recording the current command in the audit logs. rootless Force to use rootless driver (docker and podman driver only) This can be set to allow having multiple instances of minikube independently. p, -profile string The name of the minikube VM being used. one_output If true, only write logs to their native severity level (vs also writing to each lower severity level no effect when -logtostderr=true) logtostderr log to standard error instead of files If the value is 0, the maximum file size is unlimited. log_file_max_size uint Defines the maximum size a log file can grow to (no effect when -logtostderr=true). log_file string If non-empty, use this log file (no effect when -logtostderr=true) log_dir string If non-empty, write log files in this directory (no effect when -logtostderr=true) log_backtrace_at traceLocation when logging hits line file:N, emit a stack trace (default :0) b, -bootstrapper string The name of the cluster bootstrapper that will set up the Kubernetes cluster. alsologtostderr log to standard error as well as files (no effect when -logtostderr=true) Options inherited from parent commands -add_dir_header If true, adds the file directory to the header of the log messages Useful for the machine drivers when they will not start with 'Waiting for SSH'. Set to 'false' to use the command line 'ssh' command when accessing the docker machine. I will not explain what it is or what it is useful for, if you need more details please check the doc. Options -native-ssh Use native Golang SSH client (default true). This is how to perform a SSH tunnel using Golang.
