DOS errorlevel not working?

DOS errorlevel not working?

[Greg Conway]

Hi all,

I've just found DOSEMU yesterday, when I discovered I needed X windows to
run WINE!

I am trying to get the Norton Anti-Virus Scanner NAVDX.EXE working under
Linux. This is all fine, I've managed to get the
thing working, and mount the folder I wish to scan as my D: drive (has taken
me some time but there was documentation for all this on the web!!)

However, I'm having trouble with the errorlevel command, and returning the
result to Linux. Consider the following DOS program:

@echo off
c:\navdx\navdx.exe c:\virusfolder /s+ /doallfiles /zips /delete
if errorlevel 13 echo "virus"
if errorlevel 0 echo "clear"


simple stuff. Under Win2K, this program does the decent thing and returns
"virus" and "clear", as expected (DOS errorlevel command reports >= rather
then = if I remember correctly!), if I drop the EICAR test files into the
directory c:\virusfolder.

However, under DOSEMU (I'm running the binaries with FreeDOS) it returns
errorlevel 0 every time.

Any ideas what could be going wrong here? I'm pulling my hair out over this,
and have been scouring the web for examples all day with no success!!

Once I have this sorted, my final problem will be to return the errorlevel
to Linux, where I've called DOSEMU from a shell
script, so if anybody has any ideas on this as well they'd be gratefully
received - the best I've found is a posting so far
that says "how does it work? exitemu 1 doesn't do the job"!!)

Many thanks for any help received.

Regards,

Greg Conway.

Hi Harry,

Thanks for this, it looks interesting. Might well be where the rest of my
night goes.... :)

But - the reason I have arrived at this juncture, is as follows...

I have been happily setting up Linux Servers using something called Inflex
(a Linux mail scanner), using F-PROT, a free (for non-commercial use and
cheap for commercial use!) Linux virus scanner.

All was going well, until last week one of my sites was infected by a new
virus!

This appeared to be down to the date of the updates. Using Symantec NAV2002,
new definitions are released daily, and in four years of using NAV for
Windows, I've not been caught by a virus whilst NAV was installed and
enabled!!

So, putting two and two together, and allowing for the fact that Symantec
don't produce NAV for Linux, I decided to put together a scanner out of the
DOS versions of NAV... which explains where I am now!

So, whilst F-PROT and now it appears Panda are free in some cases, there is
obviously a price to pay for this... this appearing to be the rate new
defintions are released at!

So, like I said, I'll examine Panda, and I'll also continue to use F-PROT,
but what I'd like to do is add my trusted NAV into the equation.... all
working under Linux, just not returning the correct errorlevel!

So, many thanks, but my quest continues - if anybody has any further ideas
they'd be much appreciated!

Regards,

Greg.

Greg,

As you probably already know, the VirusScan dat files from McAfee (Nai) 
are updated weekly.  Hopefully I was not too confusing.  I was speaking 
of 2 different products.
