1. Introduction

   Most people will say: "A virus scanner? For UN*X? Why? Viruses do not
   work in a UNIX environment." On the first glance they are right (even
   if there are at least two viruses which run under Linux - well,
   actually they are Trojan Horses)
   
   On the second view though, imagine a heterogene network environment
   with both UN*X and DOS / Windows / Macintosh workstations. Now think
   of an UN*X server that serves Windows and/or Macintosh workstations
   via a POP3 service. Would it not be nice to ensure attachments coming
   via email are scanned for viruses before they reach a system they are
   able to infect? Well - that is what this package is for. It resides on
   the server that handles your incoming mails. When a mail arrives,
   instead of being delivered via procmail directly, is parsed through a
   script that extracts all attachments from the mail, unpacks (if
   needed) and scannes them using a professional virus scanner program.
   
  Please note:
  
   This document mainly describes the function and implementation in a
   [53]Linux environment, but it should be portable to any UN*X available
   within the limitations outlined in this document ( currently only
   Linux tested by the authors). Successful installation has also be
   reported running on SUN Solaris, *BSD, AIX and HP-UX (some with minor
   modification to the package). Links to software packages point mainly
   point to source code which should compile under different UN*X
   systems.

    2.3.1 metamail
    
   most recent version of metamail is available at:
   [89]ftp://ftp.funet.fi/pub/Linux/PEOPLE/Linus/net-source/mail/tools/.
   We do not recommend to use it anymore, as it seems not to be
   maintained and metamail can not handle MIME multipart/alternative
   messages. Please use reformime out of the maildrop package instead
   (see below). See also: README.metamail
   
    2.3.2 reformime
    
   reformime is part of the
   [90]http://www.flounder.net/~mrsam/maildrop/maildrop package.
   Please have a look at README.reformime, too.
   
  2.4 Decompressors
  
    2.4.1 uudecode
    
   Note: GNU uuencode/uudecode 1.0 distribution has been merged into GNU
   shar utilities 4.2 distribution. Look for sharutils-*.*.tar.gz
   available at: [91]ftp://ftp.gnu.org/gnu/sharutils/
   
    2.4.2 compress
    
      From the compress (4.1) manpage:
      
   Compress reduces the size of the named files using adaptive Lempel-Ziv
   coding. Whenever possible, each file is replaced by one with the
   extension .Z, while keeping the same ownership modes, access and
   modification times.
   
   Note: (un)compress is not needed as [92]gunzip is also able to
   uncompress .Z files.
   
   Source code for compress is available at:
   [93]ftp://sunsite.unc.edu/pub/Linux/utils/compress/compress.tar.Z
   
    2.4.3 gunzip
    
      From the gzip-1.2.4L.lsm file:
      
   gzip (GNU zip) is a compression utility designed to be a replacement
   for compress. Its main advantages over compress are much better
   compression and freedom from patented algorithms.
   
   Source code for gunzip is available at:
   [94]ftp://sunsite.unc.edu/pub/Linux/utils/compress/gzip-1.2.4L.tar.gz
   (also available as special [95]Pentium optimized binary version)
   
    2.4.4 unzip
    
      From the unzip-5.31.lsm file:
      
   UnZip 5.31 is a free unarchiver compatible with PKZIP archives
   (zipfiles) but not a clone of PKUNZIP. This version improves
   performance somewhat and adds a new "timestamp" function for very fast
   dating of multiple archives, but most of its new features have to do
   with better cross-platform support and/or new ports. Multi-part
   archive support is *not* yet supported (sorry!). Work on that is
   already underway, however.
   
   Source code is available at:
   [96]ftp://sunsite.unc.edu/pub/Linux/utils/compress/
   
   A tool named "zipsecure" comes with AMaViS. This program reads a zip
   file from stdin, removes any pathes of a contained file and changes
   the name of the file to a new file name. The new name starts with a
   "z" followed by the process ID and a sequence number. If any extension
   in the original name was present, it is also appended to the new name.
   
   The provided tool "securetar does similar to tar-files.
   
    2.4.5 unarj
    
      From the unarj241a.lsm file:
      
   Standard unarj un-archiver, provided with the capability of creating
   directory hierarchies.
   
   Source code is available at:
   [97]ftp://sunsite.unc.edu/pub/Linux/utils/compress/
   
    2.4.6 unrar
    
      From the unrar-2.04.1.lsm file:
      
   The unRAR utility is a freeware program, distributed with source code
   and developed for extracting, testing and viewing the contents of
   archives created with the RAR archiver version 1.50 and above.
   
   Source code is available at:
   [98]ftp://sunsite.unc.edu/pub/Linux/utils/compress/
   
    2.4.7 xbin
    
   xbin is available as:
   [99]ftp://sunsite.unc.edu/pub/packages/TeX/tools/xbin/xbinunix.c
   
    2.4.8 LHArc
    
   latest seems to be [100]version 1.14g but there is a version 1.15 at
   [101]http://shibuya.cool.ne.jp/lha/.
   
    2.4.9 bunzip2
    
   Have a look at the bzip2 homepage at:
   [102]http://sources.redhat.com/bzip2/
   
    2.4.9 zoo
    
   primary site: [103]ftp://metalab.unc.edu/pub/Linux/utils/compress/
   
    2.4.10 arc

3. Installation Instructions

  3.1 Installing the Software
  
   Installation and operation is described here only for sendmail as
   SMTP-server. (See also the [111]Future Outlook section of this
   document)
   QMail users please read README.qmail, Postfix users please read
   README.postfix and Exim users please read README.exim.
     * [112]Get the package,
     * untar contents into a temporary directory,
     * read the instructions
     * be sure all required programs have been installed
     * run ./configure
     * run make
     * run make install
     * [113]modify your /etc/sendmail.cf
     * send a SIGHUP to your SMTP server ("killall -HUP sendmail")
     * [114]test your installation
       
  3.2 Modifying /etc/sendmail.cf
  
    3.2.1 Modifying /etc/sendmail.cf manually
    
   In your sendmail configuration file (usually /etc/sendmail.cf) the
   local mail delivery agent needs to be changed (typically this is one
   of procmail, deliver or mail)
   Find the line that begins with Mlocal and change the call for the
   program which resides after the "P=" directive. This has also to be
   changed after the "A=" directive:
   For example:
   
     Mlocal, P=/usr/bin/procmail, F=lsDFMAw5:/|@SPfhn, S=10/30, R=20/40,
     T=DNS/RFC822/X-Unix,
     A=procmail -Y -a $h -d $u
     
   changes to:
   
     #Mlocal, P=/usr/bin/procmail, F=lsDFMAw5:/|@SPfhn, S=10/30,
     R=20/40,
     # T=DNS/RFC822/X-Unix,
     # A=procmail -Y -a $h -d $u
     Mlocal, P=/usr/sbin/scanmails, F=lsDFMAw5:/|@SPfhn, S=10/30,
     R=20/40,
     T=DNS/RFC822/X-Unix,
     A=scanmails -Y -a $h -d $u
     
   Please have a look at the FAQ or BUGS if this leads to a malfunction.
   Note: If you prefer the m4 technique to configure sendmail, please
   read below.
   
    3.2.2 Modifying sendmail.cf via M4 macros
    
   Add the following to you .mc file, i.e. linux.mc, just before the
   MAILER definitions:
   
     dnl change Mlocal to use AMaViS
     define(`LOCAL_MAILER_PATH', `/usr/sbin/scanmails')dnl
     define(`LOCAL_MAILER_ARGS', `scanmails -Y -a $h -d $u')dnl
     
   Note: On some systems, i.e. SuSE Linux, procmail is not suid for
   security reasons (see BUGS). So, if you're using sendmail 8.10.x or
   above, you may add
   
     dnl for security reasons on some systems procmail is not suid.
     dnl so we have to add the "o" flag and remove the "S"-flag
     dnl see BUGS for details on this issue
     MODIFY_MAILER_FLAGS(`LOCAL', `+o')dnl
     MODIFY_MAILER_FLAGS(`LOCAL', `-S')dnl
     
  3.3 Test Installation
  
   So, how do you test if your installation has been successful? Don't
   ask me to send a wild virus ;-). Instead, create a file called
   eicar.com with the following contents:
   
   X5O!P%@AP[4\PZX54(P^)7CC)7}$EICAR-STANDARD-ANTIVIRUS-TEST-FILE!$H+H*
   (The file should end up being 69 bytes long). As an alternative, feel
   free to download the file at:
   [115]http://www.eicar.org/download/eicar.com
   This should be recognized as a test pattern. It is NOT a virus, just a
   test pattern that triggers the alert. Use this file in your mail. Try
   sending it as binhex, tar'ed, gzip'ed, uuencoded, etc.
   For more information visit [116]the Eicar Anti-Virus test file webpage

   Please include information about the system you are using (eg. Linux,
   Solaris,...), the OS or distribution release (eg. RedHat 5.2, SuSE
   6.0, SUN Solaris 2.6, ...) and anything that might be useful to trace
   a bug or shortcoming (like exerpts from your logfile which ususally is
   /var/log/scanmails/logfile and/or /var/log/maillog)...
   
7. Disclaimer

   The software is provided as is. Please bear in mind that we have done
   this in our spare time. While it is as accurate as we could make it
   there is a reasonable chance that there are mistakes somewhere in
   here. If you email [120]us and tell us about them we will be happy to
   fix them but we can't take responsibility for your system. Basically
   use this at your own risk.
