## 📁 Profiles (named remotes)
|
||||
|
||||
BackTunnel supports **profiles** to simplify connections. Instead of typing
|
||||
`user@host -p PORT -l PORT …` every time, you can define defaults and named remotes in:
|
||||
|
||||
📖 Example config: see [docs/profiles.ini.example](docs/profiles.ini.example)
|
||||
|
||||
System-wide default: /etc/backtunnel/profiles.ini (admins can edit)
|
||||
Packaged example: /usr/share/backtunnel/profiles.ini

.SH DESCRIPTION
|
||||
\fBbacktunnel-share\fR starts a reverse SSH tunnel from the local (sharing) machine to a remote, reachable host.
|
||||
The tunnel exposes the local sshd (typically port 22) on a loopback port on the remote host using \fBssh -R\fR.
|
||||
The sharing ends automatically after the given \fIduration\fR via \fBtimeout\fR.

\fBbacktunnel-share\fR starts a reverse SSH tunnel from the local (sharing) machine to a remote,
|
||||
reachable host. The tunnel exposes the local sshd (typically port 22) on a loopback port on the
|
||||
remote host using \fBssh -R\fR. Sharing ends automatically after the given \fIduration\fR via \fBtimeout\fR.
|
||||
Profiles can be used to simplify the remote specification and default options.
|
||||
|
||||
With the \fB--invite\fR option, \fBbacktunnel-share\fR prints a ready-to-copy access command for the remote user,
|
||||
which can be pasted directly into a chat or terminal. The invite can also be rendered as a QR code or written to a file.
|
||||
|
||||
\fBbacktunnel-access\fR mounts the shared folder from the remote side using \fBsshfs\fR by connecting to \fBlocalhost:<port>\fR on the remote host
|
||||
(the port exposed by \fBbacktunnel-share\fR).
