Sorry, I don't know enough about tramp to diagnose this. Maybe it would help if you would say exactly what commands you gave. And does the problem occur if you start with 'emacs -Q'?

All I'm trying to do is open a single file on the remote host. I'm entering "//fqhn:/home/<myuid>/.bash_profile". I get different behavior using "emacs -Q". I don't get a timeout error, but I also don't think it even attempted to connect to the remote box. The editor view just opens with the given name, but it's empty (it shouldn't be). The "*Messages*" buffer doesn't indicate that it ever tried to make a connection. It also says "Use M-x make-directory RET RET to create the directory and its parents". The other frustrating issue with my full Emacs configuration is that when I enter the second forward slash, key response vastly, and I mean vastly, slows down. I've gone through the tramp FAQ looking for potential performance issues, but nothing has helped. -- Problem reports: http://cygwin.com/problems.html FAQ: http://cygwin.com/faq/ Documentation: http://cygwin.com/docs.html Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple ^ permalink raw reply [flat|nested] 6+ messages in thread

Sorry if I confused you by saying "commands". > I'm entering "//fqhn:/home/<myuid>/.bash_profile". I'm not aware of any valid Tramp syntax that starts with a double slash. [On Cygwin, I think file names starting with a double slash refer to network files, but I don't think this should cause Emacs to invoke Tramp.] See the section "Remote Files" in the Emacs manual. You might find this easier than the Tramp manual. In particular, I suggest you try something like /ssh:fqhn:/home/<myuid>/.bash_profile or /ssh:<user>@fqhn:/home/<myuid>/.bash_profile You can omit "ssh:' in emacs-25, but this won't be allowed in emacs-26, so you might as well get used to using it. I'm away from home at the moment and can't easily test that I've got all this exactly right. > I get different behavior using "emacs -Q".

The file you specified with the double slash syntax doesn't exist. > The "*Messages*" buffer doesn't indicate > that it ever tried to make a connection. It also says "Use M-x > make-directory RET RET to create the directory and its parents". So you must have some customization that's changing the behavior. You might have to bisect your .emacs file to find it.

If not, then add to the file the following line: (setq tramp-verbose 6) In '*debug tramp/scp remote_host_name*' buffer you'll see all interactions between tramp, ssh and your remote host. Good luck!

Well, that's odd. I decided to get back to this, and now I see that this is working perfectly fine. The only thing I've changed is setting this verbose variable to 6. However, I then changed it back to 1 and retested, and it's still working fine.
