Hi,

I am trying to edit a remote file using Tramp. I have my ssh connection
setup and it works great. But when I do a

C-x C-f /ace:~/app-defaults/Emacs

I get a message

tramp-send-command-and-check: Couldn't find exit status of `ls -d /'

after a series of other messages. I have attached my debug buffers at the
end. I do have ls aliased. But I see a --norc flag in the bash command sent
out by tramp. So I don't think that that is a problem. And I also didn't
try to press TAB for completion.

Local machine is a RedHat 7.3 and the remote machine is a Solaris 2.7
server. FWIW, I am able to connect to the remote machine and spawn
remote-compile using the ssh route. Here is what I use for that and it
works:

(setq remote-shell-program      "ssh"
      remote-compile-host       "ace"
      remote-compile-user       "kitty"
      remote-compile-run-before ". $HOME/.profile > /dev/null 2>&1"
      compile-command           "make -j4"
      )
