[pdm-devel] [PATCH pve-xtermjs 1/2] xtermjs: add support for remote node shells via PDM

[Fabian Grünbichler]

if a remote name and type is specified, adapt the API endpoint base url
accordingly, and do not send the authentication line, since there is no PDM
termproxy that handles it. instead, PDM will generate and inject the
authentication line when proxying the websocket connection to the termproxy on
the remote.
