This is also seen in 1-nofprintPass.log, where the password prompt apüpears shortly after the finferprint reader prompt: --8<---------------cut here---------------start------------->8--- 16:42:33.376427 tramp-accept-process-output (10) # *tramp/sudo root@archlinux* run t Place your finger on the fingerprint reader 16:42:33.377212 tramp-process-one-action (5) # Looking for regexp "\(\(?:Place your \(?:\(?:finger o\(?:n the reader agai\)?\|\(?:left \(?:index finger\|little finger\|middle finger\|ring finger\|thumb\)\|right \(?:index finger\|little finger\|middle finger\|ring finger\|thumb\)\) o\)n\)\|Remove your finger, and try swiping your finger again\|Swipe \(?:was too short, try again\|your \(?:finger a\(?:cross\|gain\)\|\(?:left \(?:index finger\|little finger\|middle finger\|ring finger\|thumb\)\|right \(?:index finger\|little finger\|middle finger\|ring finger\|thumb\)\) across\)\)\|Your finger was not centred, try swiping your finger again\).*[ ]*\)\'" from remote shell 16:42:33.377342 tramp-process-one-action (5) # Call ‘tramp-action-fingerprint’ 16:42:34.377959 tramp-accept-process-output (10) # *tramp/sudo root@archlinux* run nil Place your finger on the fingerprint reader Password: --8<---------------cut here---------------end--------------->8--- The regexp was detected, tramp-action-fingerprint was called, it interrupted the process, and the password prompt appeared. This was within 1 second, caused by the (sit-for 1 'nodisp) call I've added for sanity.

Otherwise, tramp-action-fingerprint wasn't called. So let's look at the other use cases. First, 1-fprintUsed.log: --8<---------------cut here---------------start------------->8--- 16:16:30.712125 tramp-accept-process-output (10) # *tramp/sudo root@archlinux* run t Place your finger on the fingerprint reader 16:16:30.712488 tramp-process-one-action (5) # Looking for regexp "\(\(?:Place your \(?:\(?:finger o\(?:n the reader agai\)?\|\(?:left \(?:index finger\|little finger\|middle finger\|ring finger\|thumb\)\|right \(?:index finger\|little finger\|middle finger\|ring finger\|thumb\)\) o\)n\)\|Remove your finger, and try swiping your finger again\|Swipe \(?:was too short, try again\|your \(?:finger a\(?:cross\|gain\)\|\(?:left \(?:index finger\|little finger\|middle finger\|ring finger\|thumb\)\|right \(?:index finger\|little finger\|middle finger\|ring finger\|thumb\)\) across\)\)\|Your finger was not centred, try swiping your finger again\).*[ 16:16:30.712552 tramp-process-one-action (5) # Call ‘tramp-action-fingerprint’ 16:16:30.712571 tramp-action-show-message (6) # Place your finger on the fingerprint reader 16:16:34.069284 tramp-process-one-action (5) # Looking for regexp "\(\(?:^\|\)[^] #-%>]*#?[]#-%>][[:blank:]]*\)\'" from remote shell 16:16:34.069358 tramp-process-one-action (5) # Call ‘tramp-action-succeed’ 16:16:34.069412 tramp-process-actions (6) # Place your finger on the fingerprint reader #$ --8<---------------cut here---------------end--------------->8--- It looks proper. First, the string "Place your finger on the fingerprint reader" was detected by the regexp. tramp-action-fingerprint was called, which has invoked tramp-action-show-message, which should have shown the message in the echo area. Did it? Some few seconds later, you have authorized with your finger, and we see the shell prompt "#$". This is detected, and the call of tramp-action-succeed finishes the initial conversation. Now the third case, 1-fprintTimeoutPass.log: --8<---------------cut here---------------start------------->8--- 16:35:02.288110 tramp-accept-process-output (10) # *tramp/sudo root@archlinux* run t Place your finger on the fingerprint reader 16:35:02.288499 tramp-process-one-action (5) # Looking for regexp "\(\(?:Place your \(?:\(?:finger o\(?:n the reader agai\)?\|\(?:left \(?:index finger\|little finger\|middle finger\|ring finger\|thumb\)\|right \(?:index finger\|little finger\|middle finger\|ring finger\|thumb\)\) o\)n\)\|Remove your finger, and try swiping your finger again\|Swipe \(?:was too short, try again\|your \(?:finger a\(?:cross\|gain\)\|\(?:left \(?:index finger\|little finger\|middle finger\|ring finger\|thumb\)\|right \(?:index finger\|little finger\|middle finger\|ring finger\|thumb\)\) across\)\)\|Your finger was not centred, try swiping your finger again\).*[ 16:35:02.288560 tramp-process-one-action (5) # Call ‘tramp-action-fingerprint’ 16:35:02.288577 tramp-action-show-message (6) # Place your finger on the fingerprint reader 16:35:32.352399 tramp-accept-process-output (10) # *tramp/sudo root@archlinux* run t Verification timed out Password: 16:35:32.352883 tramp-process-one-action (5) # Looking for regexp "\(\(?:^.*\(\(?:adgangskode\|contrase\(?:\(?:ny\|ñ\)a\)\|decryption key\|encryption key\|geslo\|h\(?:\(?:asł\|esl\)o\)\|iphasiwedi\|jelszó\|l\(?:ozinka\|ösenord\)\|m\(?:ot de passe\|ật khẩu\)\|p\(?:a\(?:rola\|s\(?:ahitza\|s\(?: phrase\|code\|ord\|phrase\|wor[dt]\)\|vorto\)\)\|in\)\|s\(?:alasana\|enha\|laptažodis\)\|wachtwoord\|лозинка\|пароль\|ססמה\|كلمة السر\|गुप्तशब्द\|शब्दकूट\|গুপ্তশব্দ\|পাসওয়ার্ড\|ਪਾਸਵਰਡ\|પાસવર્ડ\|ପ୍ରବେଶ ସଙ୍କେତ\|கடவுச்சொல்\|సంకేతపదము\|ಗುಪ್ತಪದ\|അടയാളവാക്ക്\|රහස්පදය\|ពាក្យសម្ងាត់\|パスワード\|密[码碼]\|암호\)\).*[:៖︓﹕：]?[[:blank:]]*\)\)\'" from remote shell 16:35:32.353044 tramp-process-one-action (5) # Call ‘tramp-action-password’ 16:35:32.353247 tramp-action-password (3) # Sending Password 16:35:38.499189 tramp-process-one-action (5) # Call ‘tramp-action-succeed’ 16:35:38.499212 tramp-get-connection-property (7) # process-buffer nil; cache used: t 16:35:38.499231 tramp-process-actions (6) # Place your finger on the fingerprint reader Verification timed out Password: #$ --8<---------------cut here---------------end--------------->8--- This looks also OK. Tramp has detected the string "Place your finger on the fingerprint reader" at 16:35:02, and via tramp-action-fingerprint / tramp-action-show-message it should have shown you the message. Nothing happens, and at 16:35:32 the message "Verification timed out" has appeared, following by a password request. Tramp has detected this, and sent the password. At 16:35:38, the shell prompt did appear (don't know why it took 6 seconds, perhaps manual typing of the password. So everything looks fine to me. The question remains: Did you see the fingerprint prompt in the echo area in case 2 and 3? > Best regards, Neri. Best regards, Michael.
