![]() # For example if you need to get to a machine under a different username # think of it as defaults, you can still change them on the command line. # This section tells SSH how to connect to any machine in physics.ox.ac.uk, If you are using a Physics Department Apple system then you can also add this via the Self Service application. nat, then without, and use whichever works first. nat for servers, or the occasional desktop system which isn't "in the NAT". ![]() Users in AOPP might also need to try .ac.uk ![]() If you know your desktop only by its short name, and attempts to connect to .ac.uk fail, please try using .ac.uk instead before giving up. Please note: Most or all of the desktop client machines have names of the form .ac.uk, and are said to be "in the NAT". Replace shortname with the name of the machine you are trying to connect to. ![]() This example shows how to connect to an example machine called .ac.uk, using an ssh tunnel from a remote unix client to .ac.uk. It is the users' responsibility to make sure files such as keys are backed up, they will also be regularly cleaned to prevent the disk filling up any files over 1 month old will be deleted. There are no backups in place so any files in your home directory there are to be treated as scratch. Warning: The ssh-gateway is only meant to be used as a gateway. ![]() Notices the node attribute for "linux-1" node, we set the port connection on the "SSH Options" at the node level.Log into the SSH gateway server .ac.uk using your physics authentication (without the preceding "PHYSICS\".) You can then log into systems inside our network from there. The goal of this example is that Rundeck connects to the nodes linux-1 and linux-2 through the bastion container (Rundeck cannot see linux-X nodes). Network2: bastion, linux-1 (running on port 2223), linux-2 (running on default port).scp -q -oCiphers=arcfour -oClearAllForwardings=yes -F /tmp/ssh_7xQ2 -i /tmp/ /etc/motd /tmp/motd ssh -q -oCiphers=arcfour -oClearAllForwardings=yes -F /tmp/ssh_config.zTr9j5KK -i /tmp/host1234.ssh-keyfile.4cjnI2qL whoamiīegin copy 18 bytes to node host1234: /etc/motd -> /tmp/motd Using Dry run, you might see output similar to this: - _options="-q -oCiphers=arcfour -oClearAllForwardings=yes" Here is an example that defines ssh_config file. You can define multiple lines using a trailing backslash and an indent on the following line. The Plugin List page will describe the key names to set. You can also modify the project.properties or use the API/CLI to define the plugin configuration. The page has a form with inputs to configure the connection to the bastion host. Use the Simple Conguration tab to see the configuration properties. The plugin can be configured as a default node executor and file copier for a Project. ssh-key-storage-path: Set to location in Rundeck Keystore.If the node is configured with the ssh-key-storage-path attribute, the ssh connection will use that to connect to the remote node. Dry run? If set true, just print the command invocation that would be used but do not execute the command.Consult the reference for ssh_config(5) to learn about posible settings. ssh_config: Specify Prox圜ommand and other flags.You can overwrite this attribute at node level, using ssh-bastion-ssh-config (node-executor) and scp-bastion-ssh-config (file-copier). SSH Options: Extra options to pass to the ssh command invocation.Bastion SSH Key Storage Path: Identity to use for the bastion host connection.This can be useful when defining the configuration properties. You can configure the plugin to just print the invocation string to the console. Use this plugin if you must access remote servers via a jump host. This plugin provides a node-executor and file-copier supporting ssh actions through a bastion host. OpenSSH Bastion Host Node Execution Plugins ![]()
