When starting the host (with `upterm host`) you get the url for web connexion, and the command for ssh connexion.
|
|
|
|
# Connecting to a session
|
|
ssh does not support rsa by default now
|
|
|
|
# Advanced Usage
|
|
|
|
## command at startup
|
|
|
|
- run command at startup : pass it as argument
|
|
- `upterm host -- tmux new -t pair-programming` (new tmux session)
|
|
- force every new connexion to run a command : `--force-command` parameter
|
|
- `upterm host --force-command 'tmux attach -t pair-programming'` (connect everyone to a tmux session)
|
|
|
|
> [!example] Example : tmux setup for remote pair programming
|
|
> - the host creates a new session, `remote`
|
|
> - Every client creates a new session attached to the host sesstion, `remote`
|
|
> - [p] That allows everyone to see the same session, but to be able to switch between panes and tabs independently.
|
|
> ```bash
|
|
> $> upterm host --force-command 'tmux new -t remote' -- tmux new -t remote
|
|
> ```

# The problem with ssh and rsa
|
|
- ssh doesn't support rsa algorithm anymore
|
|
- that means upterm won't work
|
|
|
|
Workaround :
|
|
- Add the public key of the person that wants to connect to the `.ssh/authorized_hosts`
|
|
- generate with `ssh-keygen`
|
|
- Use these arguments (to connect) :
|
|
- `ssh <the_hostname>@uptermd.upterm.dev -o "PubkeyAcceptedKeyTypes +ssh-rsa" -o "HostKeyAlgorithms +ssh-rsa"`
|
|
- `<the_hostname>` is given by `upterm host`
