A default value shall serve the majority. It is a rare case, that there
is no encoding routine on the remote host.

The patch is already committed to the repositories. So you shouldn't
have a problem in the future.

I'm thinking of setting tramp-copy-size-limit to 0 automatically, when
there is no remote encoding routine. But this isn't trivial.

tramp (2.1.15-pre); error on vc-bzr when scp not-exists on server


When trying to save a file on a remote host that uses bzr for version
control, and scp is not installed on the remote host, vc-bzr tries to
grab the dirstate file, but fails.  Left in the *Messages* buffer are
these messages:

    Transferring /scp:192.168.12.107:/var/www/rwanda-pilot/.bzr/checkout/dirstate to /tmp/tramp.28181DNK...
    Tramp: Waiting for prompts from remote shell
    Tramp: Process has died.
    File error: Process died
    Error: (file-error Process died)

Note that the main file is properly saved.

Your remote host returns as `uname -r' "Linux 2.6.18-6-686". I doubt,
that there is no scp installed.

And it isn't a missing remote scp who causes the trouble. In your
traces, I'll see:

> 10:26:59 tramp-do-copy-or-rename-file-out-of-band (6) # scp -p -q
192.168.12.107:/var/www/rwanda-pilot/.bzr/checkout/dirstate /tmp/tramp.28181DNK

> 10:26:59 tramp-process-actions (6) # 
> Connection to 192.168.12.107 closed by remote host.

That means, that the scp command has connected your remote host, but
the remote host was unwilling to speak with you. Maybe you can find
some information about in the remote host's log files. You might run
scp commands as given above in your terminal, plus an additional "-v"
for verbose information.

If you cannot convince scp to cooperate with that remote host, you
could consider ssh as transfer method.

Best regards, Michael.

OK, I'm convinced :-)

tramp (2.0.57); dired and smb: File no longer exists; type `g' to update dired buffer


Enter your bug report in this message, including as much detail as you
possibly can about the problem, what you did to cause it and what the
local and remote machines are.

If you can give a simple set of instructions to make this bug happen
reliably, please include those.  Thank you for helping kill bugs in
TRAMP.

Another useful thing to do is to put (setq tramp-debug-buffer t) in
the ~/.emacs file and to repeat the bug.  Then, include the contents
of the *tramp/foo* buffer and the *debug tramp/foo* buffer in your bug
report.

--bug report follows this line--

I get the dired of a window-server 2003-vmware-session via tramp-smb,
but when I use "f" to open a directory there I get: 

File no longer exists; type `g' to update dired buffer

And when I try to copy a file with "c", I get:
Cannot make local copy of non-existing file `/smb:samba%ARBEITSGRUPPE <at> telefun-demo:/D$/ftmgr.xm'

This was in *Messages*:

tramp: Opening connection for //samba%ARBEITSGRUPPE <at> telefun-demo/D$...
tramp: Started process (smbclient //telefun-demo/D$ -U samba -W ARBEITSGRUPPE)
tramp: Sending password
