[PATCH] Socket forwarding in emacsclient --tramp-prefix example |
|
Date: |
Sat, 21 Oct 2023 16:01:27 +0100 |
Previously, the emacsclient --tramp-prefix documentation suggested
using it in conjunction with a forwarded TCP port. However, OpenSSH
has supported forwarding sockets since version 6.7 (released 2014), so
let’s suggest that instead. Sockets require less manual configuration
than ports, are less likely to clash, and are more secure, so will be
a better choice for the majority of people looking to set up this
facility for the first time.
* doc/emacs/misc.texi (emacsclient Options): Suggest forwarding sockets.

Thanks, I've pushed this to the emacs-29 branch. Closing the bug (again).

You've been quiet for months, so I've assumed you've lost interest.
Best regards, Michael.
