Thanks for this. However, I don't believe we shall document this instead of server ports. Better would be to document both variants. The reason is, that sockets don't exists on every platform, see the "#ifdef SOCKETS_IN_FILE_SYSTEM" directive in emacsclient.c. Furthermore, people might run older sshd servers on remote systems, which don't support socket forwarding. It must be also at least OpenSSH 6.7, like the client on the local side. Think about routers, NAS systems, and alike, which aren't upgraded over years. As Tramp maintainer I know what I'm speaking about. The %TOKEN percent expansion (your %r and %i tokens) exists since OpenSSH 8.2 only. Best regards, Michael.

You¢re right about these kinds of systems, of course, but the old example already left a lot as an exercise for the reader: it assumes that you¢d suitably configured server-port and server-use-tcp, then somehow made ~/.emacs.d/server/server accessible to the client. Deciding on a suitable ssh -R argument for TCP forwarding doesn¢t seem like the hardest part. So, I¢m not certain that one and a half examples is better than one complete example, but, anyway, here¢s an updated patch. -- Peter Oliver ---1463811583-926039267-1697914409=:4090 Content-Type:

Otherwise, it is fine. Eli, can we still install it in the emacs-29 branch? And another question. You have already contributed to Emacs. That contribution, and your proposed changes here and in bug#66598 bring you close to the limit of changes (~15 lines), which are accepted without formal paperwork.

It would, sure, but you can’t in general tell from the local side whether the remote side has /run, nor what your UID is there. You’d need an extra round trip, for which you need ssh’s ControlPersist option to make performant. This is too complicated for a simple example. > If the socket fie is in /tmp every other user can read it, using /run/user is > more secure. No, the socket will have permissions 0700, so other users won’t be able to read it. The risk is that other users will be able to cause a nuisance by creating a file of the same name in its place. Perhaps it’s better to suggest putting the socket in the user’s home directory (which I originally discounted in case of shared NFS home directories)? -- Peter Oliver ---1463811583-835658128-1697994546=:4056-- From debbugs-submit-bounces@debbugs.gnu.org Sun Oct 22 15:42:13 2023 Received: (at control) by debbugs.gnu.org; 22 Oct 2023 19:42:13 +0000 Received: from localhost ([127.0.0.1]:48153 helo=debbugs.gnu.org) by debbugs.gnu.org with esmtp (Exim 4.84_2) (envelope-from ) id 1queKz-0003hY-H7 for submit@debbugs.gnu.org; Sun, 22 Oct 2023 15:42:13 -0400 Received: from mail-lj1-x232.google.com ([2a00:1450:4864:20::232]:50356) by debbugs.gnu.org with esmtp (Exim 4.84_2) (envelope-from ) id 1queKx-0003h7-F9 for control@debbugs.gnu.org; Sun, 22 Oct 2023 15:42:12 -0400 Received: by mail-lj1-x232.google.com with SMTP id 38308e7fff4ca-2c5629fdbf8so30542551fa.0 for ; Sun, 22 Oct 2023 12:41:42 -0700 (PDT) DKIM-Signature: v=1; a=rsa-sha256; c=relaxed/relaxed; d=gmail.com; s=20230601; t=1698003697; x=1698608497; darn=debbugs.gnu.org; h=to:subject:message-id:date:mime-version:from:from:to:cc:subject :date:message-id:reply-to; bh=X+7DH2yjIAewcBwEEaD2QqT7pvEp/MtSLKUmcX7LW/k=; b=Ii0tUZAmTMl0c1DfGConHiqzMnQDijLRIZ3DUldWoyIfplzsDR4Dz9scqiPGw2E46K /WaIq3NtcSsk7y3Pxz+vnGpyPoKZMFbr3g+zLgvsBrUdqmStlW7LOAxvyksT87ynWRHs wdg6VCaCVKCmrhtcGLny6NACu/twcpnBbCpLoU2MNgzhLXbuIZl0qin1wX33hHr2ZtT/ 5CDS5Y1lCp7SE7BVyJ5SIwz/7Rmu5t/5TKlG+7qe7erMRlsbQ07l2JkPKDL+PIyqq/fg eQpufY8vjSS8GPuca6dafL3SIlk7a1voaOKR6TzYGFHlborCh4NkvSC4qmccLKV4X1wl lUVQ== X-Google-DKIM-Signature: v=1; a=rsa-sha256; c=relaxed/relaxed; d=1e100.net; s=20230601; t=1698003697; x=1698608497; h=to:subject:message-id:date:mime-version:from:x-gm-message-state :from:to:cc:subject:date:message-id:reply-to; bh=X+7DH2yjIAewcBwEEaD2QqT7pvEp/MtSLKUmcX7LW/k=; b=fJW8r/lkvSf1e0w1yTGGirG78E0gxZbT+Mu3+S+e3+H0wRmM3W5sEFOnRqOJdWeAnQ uON68czA/5Tx+VZ56+ipHqB+StuTAPaGPIc5XExPh2WSyX10zIaKxRnDgctBK83FASON sOOqgJPMmysB0tTKTJrtEGnVW7vADmIFw2gFol7Qq96ApMQB9KTRxzA17EenWR5Vsgpd R1Xg+g5RmleeFWRX1o8Cm0N1l+igG97TX75wMFObrU+faTpNiySP9/+m7kmT9PjCrMLi U0yWWZZe7+V6K1GQaMFBmmWAdUnPcFV4KQ47Ryxuhdm50Kss672eVlZekHgy8e3xl3tj 69Fw== X-Gm-Message-State: AOJu0YwVGyZXtBQEFUzS+VJdtGfVYzs3UqOM0hll9hv0LsOF2Tt2yjAh 1CsnkpyJEhWdo0dOlEGmtWYVthEy6zZoHwcdXj29fbZeSOM= X-Google-Smtp-Source: AGHT+IHfDv9sYhBcskx1BEr3Kx/uD7LbBrxa6l3dVRiZy4X0wWmzkYdsKIOV1mTi8M3idoV6ANrILtVcJoCR17TTIfA= X-Received: by 2002:a2e:854c:0:b0:2c5:1eb6:bd18 with SMTP id u12-20020a2e854c000000b002c51eb6bd18mr4830172ljj.53.1698003696848; Sun, 22 Oct 2023 12:41:36 -0700 (PDT) Received: from 753933720722 named unknown by gmailapi.google.com with HTTPREST; Sun, 22 Oct 2023 12:41:36 -0700 From: Stefan Kangas MIME-Version: 1.0 Date: Sun, 22 Oct 2023 12:41:36 -0700 Message-ID: Subject: control message for bug #66667 To: control@debbugs.gnu.org Content-Type: text/plain; charset="UTF-8" X-Spam-Score: 0.0 (/) X-Debbugs-Envelope-To: control X-BeenThere: debbugs-submit@debbugs.gnu.org X-Mailman-Version: 2.1.18 Precedence: list List-Id: List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , Errors-To: debbugs-submit-bounces@debbugs.gnu.org Sender: "Debbugs-submit" X-Spam-Score: -1.0 (-) severity 66667 wishlist quit From unknown Sun Jun 22 00:26:35 2025 MIME-Version: 1.0 X-Mailer: MIME-tools 5.505 (Entity 5.505) X-Loop: help-debbugs@gnu.org From: help-debbugs@gnu.org (GNU bug Tracking System) To: p.d.oliver@mavit.org.uk Subject: bug#66667: closed (Re: bug#66667: [PATCH] Socket forwarding in emacsclient --tramp-prefix example) Message-ID: References: <87ttnl8pgp.fsf@gmx.de> <20231021150127.66683-1-git@mavit.org.uk> X-Gnu-PR-Message: they-closed 66667 X-Gnu-PR-Package: emacs X-Gnu-PR-Keywords: patch Reply-To: 66667@debbugs.gnu.org Date: Wed, 10 Jan 2024 10:16:02 +0000 Content-Type: multipart/mixed; boundary="----------=_1704881762-24857-1" This is a multi-part message in MIME format... ------------=_1704881762-24857-1 Content-Disposition: inline Content-Transfer-Encoding: quoted-printable Content-Type: text/plain; charset="utf-8" Your bug report #66667: [PATCH] Socket forwarding in emacsclient --tramp-prefix example which was filed against the emacs package, has been closed.

However, OpenSSH has supported forwarding sockets since version 6.7 (released 2014), so let’s suggest that instead.

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. --- doc/emacs/misc.texi | 18 ++++++++---------- 1 file changed, 8 insertions(+), 10 deletions(-) diff --git a/doc/emacs/misc.texi b/doc/emacs/misc.texi index a05b7f6c6ea..93771832ff5 100644 --- a/doc/emacs/misc.texi +++ b/doc/emacs/misc.texi @@ -2158,8 +2158,9 @@ emacsclient Options Set the prefix to add to filenames for Emacs to locate files on remote machines (@pxref{Remote Files}) using TRAMP (@pxref{Top, The Tramp Manual,, tramp, The Tramp Manual}).
