Subject RE: [users@httpd] Possible virus via httpd server
Date Wed, 06 Jan 2016 03:49:41 GMT
Problem solved, and it was not a virus.  I have a complex cgi writen in C++.
While DBAN was running, it occured to me that the binary file I was getting
was around the same size as my cgi binary.  After the reinstallation, diff
informed that it was in fact the cgi I was getting, the notwithstanding the
peculiar names.  I reread the cgi documentation and spent some time
trying variations in my config.  I then decided to take a look at
01-cgi.conf,
which is included in httpd.conf . There I read that what it did depended on
the results of 00-mpm.config . I immediately (after wasting 2-3 days)
suspected an order problem in the includes, and sure enough, they were
out of order, which I corrected in under one minute.  It now works with
no problem.
 
Thanks for your efforts and interest.
Mike.

I don't think index.html was changed, but I only took a quick look.
I have it backed up in a tgz file, so when the Linux box comes back up
(maybe tomorrow), I'll take a closer look
 
It is also possible that there was something wrong with httpd.config .
It is quite complex, with numerous RewriteRule, etc.  However, even
when I commented out ALL the virtual hosts, the problem persisted.
But if I left a simple vhost and put a RewiteRule that (for reasons that I
don't
know) it didn't like, then it returned a failure.  When I put it back
together,
I'll build up httpd.config slowly.
 
Thanks,
Mike.

Was the index.html file modified in anyway?  Did it call the executable?
Any rewrites or any other files added to the path index.html resided?

It was not overwritten.  If you looked on the server, it was just fine.
But an executable was delivered instead.  In any case, it is gone
with the wind -- DBAN is now running on the server. Hopefully,
the reinstallation will work better.

Following your suggestion, I made use of my daily backups to install
the httpd.conf from two days ago, when all was well. The problem was
the same.  I tried sublitting a file to sophos, but I would have to
join, and I am not ready for that.  See also my next email.

Still heading toward DBAN.

Thanks,
Mike.
