Hi Michael, I am happy to write to you again, and for a start I would like to tell you big BIG THANK YOU! For providing this excellent tramp module which I and thousands of emacs users are using worldwide! I am software developer and DevOps and this exact feature makes my life so much better!
Nice to meet you again, btw I have seen your youtube videos, it was nice to see you in live mode in video :-) https://www.youtube.com/watch?v=qu97wa8YTrU&t=1697s Both my problems are not urgent, but it makese sense to fix them earlier or later. OK, so switching to actual problems: One problem is this (easy to reproduce) --------------------------------------- 1. As example I am taking remote server 'hosting' where 2 facts are true: - I have root@hosting account - There is *no* ubuntu@ account on that host 2. Assume I forget that I have to login to root@ directly, and trying to do it via 'ubuntu' account first: Trying to open: /ssh:ubuntu@hosting|sudo:root@hosting: leads to: Tramp: Opening connection for root@hosting using sudo... Tramp: Sending command ‘exec ssh -l ubuntu -e none hosting’ Tramp: Waiting for prompts from remote shell... Tramp: Sending password 3. Now, I see this prompt for password, I realize that I should be logging there directly. I try to do it, now directly: /ssh:root@hosting: Tramp: Waiting for prompts from remote shell... Tramp: Sending password Tramp: Waiting for prompts from remote shell...failed Tramp: Opening connection for root@hosting using ssh...failed .. so the problem is that despite the fact that now I am specifying /ssh:root@hosting: directly, it still tries to invoke ssh:ubuntu@ first. tramp-cleanup-all-connections does not help. 2nd problem ----------- I have 2nd problem, and I am not sure if this is reflection 1st or something else. Sometimes, I can have several paths to connect to remote host. For example: This paths allows me to use custom defined 'docker' tramp method which I use to connect to docker container in privileged mode on hosting server: /ssh:root@hosting|docker:some.site.name: But then, I might connect to the same site using direct 'ssh' when container has ssh access: /ssh:client@docker:some.site.name#port: I am not sure if different #port here is causing this but it still tries to connect to previous host using root ->docker path. Again, this does not help: M-x tramp-cleanup-all-buffers M-x tramp-cleanup-all-connections and so in such case I have to restart emacs completely to get to host correctly. Would be great if you advice me what to do or find out how to fix those issues. JFYI as a DevOps I find it very useful to be able to connect into Docker, Openshift and Kubernetes containers with a great tool which Emacs is (not only editor, but org-mode and other things makes it easy to execute/filter results etc). Here are my custom connectors (up to you may me makes sense to include some of them into official support): ;; Problem with su: often many system accounts are hidden under /sbin/nologin due to reasons explained here: ;; https://unix.stackexchange.com/questions/155139/does-usr-sbin-nologin-as-a-login-shell-serve-a-security-purpose ;; ... as result 'su' won't work, but with lisp it is easy to define 'sush' which will do -s /bin/sh (push (cons "sush" '((tramp-login-program "su") (tramp-login-args (("-") ("%u") ("-s" "/bin/sh"))) (tramp-remote-shell "/bin/sh") (tramp-remote-shell-login ("-l")) (tramp-remote-shell-args ("-c")) (tramp-connection-timeout 10))) tramp-methods) ;; ;; from https://emacs.stackexchange.com/questions/17543/tramp-mode-is-much-slower-than-using-terminal-to-ssh (setq remote-file-name-inhibit-cache nil) (setq vc-ignore-dir-regexp (format "%s\\|%s" vc-ignore-dir-regexp tramp-file-name-regexp)) (setq tramp-verbose 1) (push (cons "ocrsh" '((tramp-login-program "oc") (tramp-login-args (("rsh") ("%h") ("/bin/sh"))) (tramp-remote-shell "/bin/sh") (tramp-remote-shell-args ("-i")))) tramp-methods) (push (cons "kube" '((tramp-login-program "kubectl") (tramp-login-args (("exec") ("%h") ("-it") ("/bin/sh"))) (tramp-remote-shell "/bin/sh") (tramp-remote-shell-args ("-i")))) tramp-methods) WBR, and again thank you!
