Short: V1.54 Check for Archives/Packers/Viruses
Author: stoecker@amigaworld.com (Dirk Stoecker)
Uploader: stoecker@amigaworld.com (Dirk Stoecker)
Type: util/arc
Requires: util/arc/xadmaster.lha
util/pack/xfdmaster.lha
util/virus/xvsLibrary.lha
util/pack/xpk_User.lha
Version: 1.54
This program uses xfdmaster.library (see util/pack/xfdmaster.lha) and
xvs.library (util/virus/xvsLibrary.lha) for packer and virus scanning.
The xadmaster.library (see util/arc/xadmaster.lha) is used to dearchive
file and disk archives.
NOTE: xadmaster.library is Shareware, so think about registering when
using this utility together with that library (and without it's nearly
useless). See conditions in xadmaster.library distribution.
The xfdmaster.library is needed to run the utility. The xvs.library and
xadmaster.library are recommended! The xpkmaster.library is needed with
ASKPWD password only (and to decrunch XPKF files).
CheckX unpacks archives and packed files as deep as possible:
- you can unarchive a crunched archive as well
- multiple crunched files can be decrunched
- multiple archives can be extracted
- multiple disk archives can be extracted
- linked and crunched and archived files are no problem
This all depends mainly on your memory size! If have around 50MB and have
only little problems with really large archives.
Call CheckX with a ? and you get following argument list:
FROM,LOG,SAVE/K,ALL/S,ASKPWD/S,AUTOMOUNT/S,PRINTALL/S,PRINTEXEC/S,
NODECRUNCH/S,NOUNLINK/S,NOUNARCHIVE/S,NOUNTRACK/S,NOTRACKCUT/S,NOSTRIP/S,
NOVIRUS/S
Enter a ? again and you get a short doc:
FROM source file or directory - may contain patterns
LOG log file name
SAVE directory, where decrunched files are saved
ALL scan deep into directories
ASKPWD ask for password when needed (needs xpkmaster.library)
PRINTALL print all filenames
PRINTEXEC print names of all executable files
AUTOMOUNT automatically mount RDx: device when needed
NODECRUNCH do not decrunch files with xfdmaster
NOUNLINK do not unlink files with xfdmaster
NOUNARCHIVE do not call archiver for unarchiving file archives
NOUNTRACK do not call archiver for unarchiving track archives
NOTRACKCUT do not call archiver for partially track archives
NOSTRIP do not strip useless hunks
NOVIRUS do not scan with xvs.library for viruses
A bit more explanation:
LOG The output is written to a file as well as to the standard
output stream. The main purpose CheckX was written for is
to scan for crunched files and to test the decrunch
routines. So the logging may take some more time, but is
very stable, as the last log-entry is always the file which
possibly crashed the machine.
The logfile can be accessed by other progress for read and write
the whole time CheckX works (and surely after that). But writing
is not recommended, as this may produce a corrupted file.
SAVE If this keyword is given, all uncrunched/unlinked/stripped
files will be saved in the directory given with that keyword.
The directory must already exist! Sub directories are created
automatically.
If files are unlinked, they get saved with .1, .2, ...
extensions. Address crunched files are not saved. Use
xfdDecrunchAddr or xfdDecrunch to do so.
AUTOMOUNT To unarchive disk archives (DMS, Zoom) a destination device
is needed. These devices are called RD0: to RDn: and for high
density disks RH0: to RHn:. CheckX can automatically mount
these or you may mount them before calling the program.
The number n depends on the archiver depth, so normally RD1:
should be the highest one really needed. High density disks
(RHn:) are not supported yet, as DMS seems to have problems
here.
NOTRACKCUT This prevents unarchiving of cutted (DMS) archives. Splitted
DMS-Archives may produce strange errors, but can be checked
correctly, when the two parts are directly after another (e.g.
no other track archive is between them). In this case the first
file shows some XPKCERR_READWRITE and the second one the
correct stuff. I checked EuroScene1 CD which has a lot cutted
archives and newest xfdmaster.library had no problems, so
probably this option is not needed anymore.
CheckX cannot scan files, which are read-protected. You get CheckX error 4
as result in that case. Unprotect files and scan again when you want. For
files contained in archives, the protection bits are ignored.
CheckX is completely reentrant and may work fine twice or more times
parallel (You can set the pure file protection bit and make it resident),
with one exception: Destination Disks (RDn: or RHn:) can be accessed only
by one tool! So when source path contains disk archives, start only one
copy of CheckX or use NOUNTRACK!!! It is not recommended to call it multiple
times as CheckX normally needs lots of memory.
This is a batch tool, so drink a coffee or two or three during its work.
Check the logfile afterwards. Use a text-editor and scan case sensitive
for "-Virus" and you get lines which a related to viruses (and mostly
only the important lines). A scan with "XFD", "XAD" or "CheckX" brings
lines which produced errors.
The complete number of found viruses is logged at the file end (If the
scan found some of them). Also the scan time is logged.
If the permanent file scrolling slows down your computer try setting the
output stream to a raw mode display using following redirect command:
">RAW:0/11/640/50/CheckX-Output/AUTO/CLOSE/WAIT".
To get CheckX really silent either use LOG option and call CheckX with
">NIL:" or redirect normal output into logfile with ">filename".
CheckX detects all the viruses found by xvs.library, which contains the
complete antivirus knowledge of VirusZ utility by Georg Hörmann. CheckX
cannot detect viruses in memory or remove detected viruses. You still
need antivirus software like VirusZ, VT or Virus_Checker. I always run
VirusZ in the background to check for viruses.
CheckX also scans disk archive information texts for packers and viruses.
At the moment CheckX does not scan bootsectors of dearchived disks. This
will be implemented soon.
If there are serious errors, please report them, but CheckX has a long
way of development and I hope it is really stable now (as well as
xfdmaster.library is now).
Send me files, which cause the system to bring Enforcer/MungWall/PatchWork
Hits or crash the computer. If the files are larger, please contact me
first.
Stuff which becomes obsolete soon:
As xadmaster.library is still in development some important archivers are
still missing, so internal routines detect LhA, LhASFX, Zip, Zoo and Arc
archives. The corresponding programs are called to dearchive these files.
Especially in UNARCHIVE mode this tool may need lots of memory (when T: is
assigned to ram disk). Keep that in mind! Every checked file is completely
loaded into memory! If you have low memory I would suggest assigning T: to
harddisk to get better results. Note this is no longer necessary, when
xadmaster.library includes all the missing clients, so I will not create
a TEMPDIR argument or something like that.
The program works fine with following archivers:
Arc 0.23 50328 bytes
LhA 1.98 52348 bytes
UnZip 5.32 92992 bytes
Zoo 2.1 Beta 3 54608 bytes
This program is Freeware. Use it as you want, but WITHOUT ANY WARRANTY!
