upgrade:
Start mbsetup and exit. If you have a clamd running on some
server (or bbs machine), you can switch to use stream
scanning. See the manual for details.
mbselib.h:
Added file virscan function.
Added stream scanning for ClamAV, scanning is 10 times faster

A new feature is stream scanning. In this setup you need a virus scanner loaded as a daemon and it
must listen to a TCP/IP port to receive commands and data to scan. Currently this is only implemented
for ClamAV, but F-Prot may follow. First you need a machine where <b>clamd</b> is running, this
can be a remote machine but of course also the bbs machine itself. ClamAV needs to be configured
so that it listens to a TCP/IP port, and depending on other things on the local socket too.
Recent versions of ClamAV can do both together. Change your <code>/etc/clamav/clamd.conf</code> to
contain the following lines:
<pre>
# Path to a local socket file the daemon will listen on.
# Default: disabled (must be specified by a user)
LocalSocket /var/run/clamav/clamd
# Remove stale socket after unclean shutdown.
# Default: no
#FixStaleSocket yes
# TCP port address.
# Default: no
TCPSocket 3310
# TCP address.
# By default we bind to INADDR_ANY, probably not wise.
# Enable the following to provide some degree of protection
# from the outside world.
# Default: no
#TCPAddr 127.0.0.1
</pre>
I left the comment for the TCPaddr, but it's up to you to protect the clamd server. After you
restart <b>clamd</b> test the connection with <code>telnet host.where.clamd.runs 3310</code>,
type VERSION followed by a return and you should see the ClamAV version. If that works, you can enable
the ClamAV stream scanner in mbsetup and disable the old commandline scanner.<BR>
So why would you use this. It's about 10 times faster then the commandline scanner.
