---|
This configuration will allow access to any host which mounts the same $HOME directory. |
Other Notes
SSH Agent is required
If you have logged in but ssh fails to connect, it may be that your SSH agent is not running.
The Agent can be started and tokens refreshed this way:
Code Block |
---|
|
eval $(ssh-agent -s)
tsh logout
tsh login |
And this will make sure the Agent continues to run in your environment:
Code Block |
---|
|
echo 'eval $(ssh-agent -s)' >> ~/.bash_profile |
SCP, X11, Agent, and Port Forwarding
scp, agent, and port forwarding will work through the Teleport gateway.
Note |
---|
X11 forwarding will work in a couple of months when we have an update from the vendor. |
Legacy Configuration
For OpenSSH clients older than 7.3, the following configuration can be used:
Code Block |
---|
|
# ~/.ssh/config file:
Host ecgate
User ab0
ProxyCommand /usr/bin/ssh -q -W %h:%p ab0@shell.ecmwf.int
|
Difficult client environments
You might not be able to download and run tsh
, or access our web login service, from where you wish to use ssh.
Instead you can use (or copy) the identity file which tsh
stores in $HOME
:
Code Block |
---|
|
# ~/.ssh/config file:
Host ecgate
User ab0
IdentityFile ~/.tsh/keys/shell.ecmwf.int/firstname.lastname@ecmwf.int
ProxyCommand /usr/bin/ssh -q -i ~/.tsh/keys/shell.ecmwf.int/firstname.lastname@ecmwf.int -W %h:%p ab0@shell.ecmwf.int |
This is a good way to access Teleport credentials via a shared file system from any host.
Windows Clients
There are various ways to initiate SSH from Windows 10, so it depends on your system and your preferences.

- Start the Windows SSH Agent Service
- Download tsh (you may need to instruct antivirus software to ignore the file)
- Login using tsh (you will always need to specify the --proxy setting)
- Use an SSH config as below:
Code Block |
---|
| # Windows currently has a bug, you need the full path to ssh or you will get:
# posix_spawn: No such file or directory
Host *.ecmwf.int
User ab0
ProxyCommand C:\Windows\System32\OpenSSH\ssh.exe -q -W %h:%p ab0@shell.ecmwf.int
# this assumes the SSH Agent is running, otherwise add:
# Host shell.ecmwf.int
# IdentityFile ~/.tsh/keys/shell.ecmwf.int/firstname.lastname@ecmwf.int
|
Tip |
---|
The Windows 10 Terminal is a decent tabbed command line interface (albeit with no X support). New sessions can be configured following this example: Code Block |
---|
| {
"guid": "{717406b0-06cb-454c-a0c4-875267fa373d}", # run "[guid]::NewGuid()" in a PowerShell to generate this
"name": "ecGate",
"commandline": "ssh ab0@ecgate.ecmwf.int"
"suppressApplicationTitle": true,
"hidden": false,
"fontSize": 10,
"fontFace": "Fira Code",
"cursorShape": "filledBox",
"cursorColor": "#073642",
"colorScheme": "Solarized Dark",
