Turn Tramp off

Turn Tramp off

[Perry Smith]

Hi,

I'm current rlogin'ed to a site I can't ssh to and I don't need tramp right now.  Is there a quick easy way to just turn it off?

Thanks,
pedz

Setting tramp-mode to nil is said to disable it, but if I remember
correctly I couldn't get that to work when I didn't want tramp.

Yea.  I found that via google but apropos doesn't even mention that.  I later found tramp-unload-tramp.  This causes ange-ftp to be used -- which is ok I suppose.  Still is wasting time on a feature that I don't want right now.  Its a super cool feature when you want it but right now its just bogging me down.

Alternatively, can't yhou setup a tramp method that uses ftp to connect
to that host? IIRC, the 'default' method is ssh/scp, but if you define a
specific method for a host it will use that.

Yea, I'm sure you can.  I have just not had the time to learn tramp well enough.  I was hot on a debugging path and just needed it out of the way.

More often than not, I'm not interested in its features.  I need to learn how to set the defaults so it is off and then enable it when I want to use it.

I want to do rlogin or telnet inside emacs so I have a complete history of what happens.  But that kicks off tramp and (often) I'm not interested in it.  And, I don't do this very often so I haven't taken the time to learn the neat way of doing things.

Can you try removing the two tramp entries in file-name-handler-alist?
Personally I think tramp should not be invoked automatically unless a
user set it up to.

If you tell us in which way you find it to be active, that would help.

each time I cd to a directory, it kicks in and tries to ssh to the site.  If I unload it then ange-ftp does the same thing (tries to log in except using ftp in this case).

Sounds like a problem that should be either fixed in Tramp, or should be
easier to squash for the user.  Please M-x report-emacs-bug.

Hi,

I'm using ido and I wasn't able to switch off tramp by setting
tramp-mode to nil until I set ido-enable-tramp-completion to nil too.

I don't understand your scenario. Tramp is invoked for special file
names. How does this corelate with rlogin and cd?

Could you, please, show your use case, starting with 'emacs -Q'?

Thanks, and best regards, Michael.

You are correct.  Sorry about that.  If I do it with -Q, tramp doesn't get involved when I do a simple rlogin followed by cd.  In fact, without -Q, I can't even get past the rlogin without tramp getting involved.

One place it gets invoked is because I have ido-mode set.  But even if I turn that off, it still gets loaded somehow.

How do I track down why its getting loaded?  I've grep'ed all my files in .emacs.d and its not there.  It must be some other package I'm using which is loading it.

Thank you for your help,
Perry

Maybe by using this little piece of code:

	(defadvice load (before debug-log activate)
	  (message "(Tipp von Kai G) Loading now: %s" (ad-get-arg 0)))

Very cool.  I've heard but never played with advice.  This will give me a chance to learn lots of stuff.

Of course, that reminds me of the plague in my counselor's office:

"Take my advice,
I'm not using it"

Thanks again,

Eval after Emacs' startup

  (setq debug-on-quit t)

When Tramp asks you for the password, enter "^G". This should produce a
backtrace, which might tell us the reason why Tramp is invoked.

Sigh!  Finally.  If anyone is interested:

I tried the "advice" but for some reason, the advice didn't trigger when Tramp is loaded.  I assume that is because it is getting autoloaded which doesn't use load?  The ^G didn't give much of a clue.  The stack I got was:

But why was tramp loaded in the first place?  So, I ended up removing the rlogin.elc and the tramp.elc and added

(debug-on-entry 'tramp-register-file-name-handlers)

just after it was defined.  I didn't that a couple of different ways and got the same stack (below).  The stack seems like it left off the initial N frames.

But I finally figured out that it was because rlogin-directory-tracking-mode was set.  I found that set in one of my older init files.  So, I cleared that.  That solved the initial problem of starting emacs and immediately doing the rlogin.  But I also have ido set and I was sure that it called tramp too.  So, I triggered ido to load tramp and found that there is ido-enable-tramp-completion.  I think I'm not tramp-less :-)

Thanks guys.

Disabling rlogin-directory-tracking-mode and ido-enable-tramp-completion
has solved your problem? Well, I'll add it to the Tramp documentation.
