- !!! VIRUS WARNING !!! I do not know if VALIDCHR.COM is virus free !!!
- I think that my system is virus free here because I do not run any games
- or other copied software. I only run Shareware/Freeware etc. from CD-ROMs
- or from registered disks, however I do not use viral scanners because
- I have not registered any (I consider `having no sex' is better than
- `testing for AIDS on a regular basis', if you know what I mean).
-
- This is VALIDCHR, a little DOS program I wrote to create
- an apropriate `valid chars =' config parameter.
- It is freeware and is thought to be distributed freely with Samba.
-
- WARNING:
- Your SMB driver may use another character map as the one VALIDCHR
- sees. The only way you can tell this is that some file names fail.
- Under Win95 everything is fine, though.
-
- Usage:
- c:
- mkdir junk_dir
- cd junk_dir
- a:validchr > a:output.log
- cd ..
- rmdir junk_dir
-
- Siedeffects:
- Files named *.TST may be deleted.
-
- Verification:
- For diagnostic purpose you can run VALIDCHR on a Samba mounted drive.
- Then you can use unix diff to compare the output of the network and
- the hard drive. These two outputs usually differ! However there
- should be few differences. I get following on Win95 (c: visa e:)
- 104c104
- < 152: length 0
- ---
- > 152: 95
- (diff line for `valid chars =' deleted because it's uninteresting)
- You can see, `y diaresis' can be mapped on the network drive while
- it cannot be mapped on the hard drive. Everything else is identical.
- However this gives a hint that one can improve the mapping.
-
- Bugs:
- Yes, probably some.
-
-
- VALIDCHR must be run on the system which character mapping should be probed.
- It must be run on the hard drive for this. VALIDCHR ALTERS THE CURRENT
- DIRECTORY AND REMOVES SOME FILES, SO ALWAYS RUN IT IN A junk DIRECTORY !!!
- You should redirect the output of VALIDCHR. At the end of the output is a
- line like
- valid chars = x:y y:x x:x ... a:b c ...
- which is suitable for your smb.conf file. (you should remove the DOS CR
- character, because DOS uses CRLF while Unix uses LF only.)
-
- Note that some mappings at the beginning of the `valid chars =' line like
- A:B B:A B:B
- might look a little bit strange to you, however sometimes character A
- has to be mapped to character B independently of a default mapping
- to uppercase or lowercase while character B must not be touched. I found
- this out the hard way ... Consider it a crude workaround, because Samba
- lacks the possibility to map characters in one direction only!
-
- VALIDCHR usually issues one warning for character 32.
- You may ignore these and any other warnings.
-
- VALIDCHR does not test for character NUL (this is the directory end marker).
-
- validchr.c is the source code to validchr.com
- You may do anything with the source code (copy, change, sell, burn)
- validchr.com is a Borland C compiled binary.
- Beware, it may contain a virus (if my system contains one).
- nwdos70.out is the output of an VALIDCHR-run under Novell DOS 7.0
- while no codepage (no display.sys) was active.
- msdos70.out is the output of an VALIDCHR-run under MS-DOS 7.0 (Win95 DOS)
- while codepage 850 was active.
-
- I have no other MS-DOS systems at home currently.
- (I have access to MS-DOS 3.0, 3.2, 3.3, 5.0 and 6.22, however I have no time
- to run VALIDCHR there)
-
- Some words to the output
- (for people not fammiliar with programming language C):
-
- probed_char: [text] mapped_char
-
- probed_char is the character probed to be written to disk
- text may be empty or contain:
- open File could not be opened.
- close File could not be closed (should not happen)
- length File name was shortened (usually occurs on SPC)
- unlink File cannot be unlinked (usually when open fails)
- mapped_char is the character which is used by MS-DOS in the directory
- This is usually the uppercase character.
- The mapped character is 0 if something failed (you may say
- that the character is not supported)
-
- The last line in the output is documented in the smb.conf manual page ;)
