bug#50399: TRAMP can't connect to Win 2000 (smb, ftp, telnet)

[Bad Blue Bull]

Hi, I applied patch to tramp-smb.el,

here's tail of debug buffer:

---start---

00:48:03.466290 tramp-process-one-action (5) # Looking for regexp "\(^.*\(Connection \(?:\(?:clo\|refu\)sed\)\|Host key verification failed\.\|Login \(?:[Ii]ncorrect\)\|N\(?:ame or service not known\|o supported authentication methods left to try!\)\|Permission denied\|\(?:Sorry, try again\|Timeout, server not responding\)\.\).*\|^.*\(Received signal [[:digit:]]+\).*\)\'" from remote shell

00:48:03.466435 tramp-process-one-action (5) # Looking for regexp "\(Connection\( to \S-+\)? failed\|Read from server failed, maybe it closed the connection\|Call timed out: server did not respond\|\S-+: command not found\|Server doesn't support UNIX CIFS calls\|\(?:ERR\(?:DOS\|HRD\|SRV\|bad\(?:file\|pw\)\|filexists\|no\(?:access\|mem\|suchshare\)\)\|NT_STATUS_\(?:ACC\(?:ESS_DENIED\|OUNT_LOCKED_OUT\)\|BAD_NETWORK_NAME\|C\(?:ANNOT_DELETE\|ONNECTION_\(?:DISCONNECTED\|RE\(?:FUSED\|SET\)\)\)\|D\(?:IRECTORY_NOT_EMPTY\|UPLICATE_NAME\)\|FILE_IS_A_DIRECTORY\|HOST_UNREACHABLE\|I\(?:MAGE_ALREADY_LOADED\|NVALID_\(?:LEVEL\|PARAMETER\(?:_MIX\)?\)\|O_TIMEOUT\)\|LOGON_FAILURE\|N\(?:ETWORK_ACCESS_DENIED\|O\(?:T_\(?:A_DIRECTORY\|\(?:IMPLEMEN\|SUPPOR\)TED\)\|_\(?:LOGON_SERVERS\|SUCH_\(?:FILE\|USER\)\)\)\)\|OBJECT_\(?:NAME_\(?:COLLISION\|\(?:INVALI\|NOT_FOUN\)D\)\|PATH_SYNTAX_BAD\)\|PASSWORD_MUST_CHANGE\|RE\(?:SOURCE_NAME_NOT_FOUND\|VISION_MISMATCH\)\|SHARING_VIOLATION\|TRUSTED_RELATIONSHIP_FAILURE\|UNSUCCESSFUL\|WRONG_PASSWORD\)\)\)\'" from remote shell

00:48:03.893989 tramp-smb-maybe-open-connection (3) # Opening connection for //nicolas@win2k/C$...failed

---end---

 

here's *tramp/smb nicolas@win2k* content:

---start---

Try "help" to get a list of possible commands.

[?2004hsmb: \>
---end---

 

I guess patch is applied, in tramp-smb.el I see from line 2049:

---start---

        (let* ((coding-system-for-read nil)

           (process-connection-type tramp-process-connection-type)

           (p (let ((default-directory

                  (tramp-compat-temporary-file-directory))

                (process-environment

                 (cons (concat "TERM=" tramp-terminal-type)

                   process-environment)))

            (apply #'start-process

                   (tramp-get-connection-name vec)

                   (tramp-get-connection-buffer vec)

                   (if argument

                   tramp-smb-winexe-program tramp-smb-program)

                   args))))

---end---

this happens when pass file name as argument to Emacs, when browsing with C-x C-f, I don't know, sometimes it's success sometimes fail.

Just right now I tried to open a file, first I got error message(tree connect failed: NT_STATUS_BAD_NETWORK_NAME etc)  suggesting to use tramp-cleanup-connection, then maybe half minute after the file was opened in buffer (I didn't even touch anything).

Debug buffer attached if it can help...

Hi,
 

 I tried emacs --eval '(setq tramp-verbose 6)' /smb:nicolas@win2k:/C$/boot.ini
 debug buffer (very big, 12M this time)
 https://drive.google.com/file/d/1hSgQ2XUaZLGg8NSbb1sI1zluotn4Z4ye/view?usp=sharing

Very strange:

--8<---------------cut here---------------start------------->8---
19:29:40.987633 tramp-smb-maybe-open-connection (6) # smbclient //win2k/C$ -U nicolas -s /dev/null --option client min protocol=NT1
19:29:49.233560 tramp-search-regexp (1) # Quit: "Quit", ""

Try "help" to get a list of possible commands.
^[[?2004hsmb: \>
--8<---------------cut here---------------end--------------->8---

Very strange. There are ANSI ESCAPE sequences prior the "smb: >" prompt,
which are unknown to Tramp. I can reproduce the problem locally.

The appended patch fixes this for me, could you pls test?

Best regards, Michael.
