Description of problem: Mimedefang doesn't autodetect virus scanner Version-Release number of selected component (if applicable): mimedefang-2.64-1.fc7 How reproducible: Always Steps to Reproduce: 1. Install clamav (yum install clamav) 2. Install mimedefang (yum install mimedefang) 3. Try to get mimedefang to check for viruses Actual results: No virus checking Expected results: Virus checking Additional info: In /usr/bin/mimedefang.pl at line 124 onwards, all of the auto-detecting code for the virus scanners is disabled: $Features{'Virus:AVP'} = ('/bin/false' ne '/bin/false' ? '/bin/false' : 0); $Features{'Virus:AVP5'} = ('/bin/false' ne '/bin/false' ? '/bin/false' : 0); $Features{'Virus:KAVSCANNER'} = ('/bin/false' ne '/bin/false' ? '/bin/false' : 0); ...etc.. This is a compile-time issue, as the mimedefang configure process fills in the scanners it finds: $Features{'Virus:CLAMAV'} = ('/usr/bin/clamscan' ne '/bin/false' ? '/usr/bin/clamscan' : 0); $Features{'Virus:CLAMD'} = ('/usr/sbin/clamd' ne '/bin/false' ? '/usr/sbin/clamd' : 0); Seems redundant to me to check for virus scanners at compile time AND run time. I suspect this is an easy fix! :-)
Whoops, I didn't think that one through. The code I copied+pasted doesn't actually check anything, it could have been replaced with a constant. There is code later that checks to make sure the selected antivirus program is running, but the code I pasted above will enable or disable those checks. It should really be something like: $Features{'Virus:CLAMD'} = (-e '/usr/sbin/clamd' ? '/usr/sbin/clamd' : 0);
Penelope, thanks for your report. Unfortunately, I only can set the paths for a few less virus scanners delivered with Fedora, because the path can vary for the commercial ones heavily. I'm not using a virus scanner within MIMEDefang, but AFAIK you can simply set $Features{'Virus:CLAMAV'} = "/usr/bin/clamscan"; $Features{'Virus:CLAMD'} = "/usr/sbin/clamd"; in your mimedefang-filter (the configuration file).
This message is a reminder that Fedora 7 is nearing the end of life. Approximately 30 (thirty) days from now Fedora will stop maintaining and issuing updates for Fedora 7. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as WONTFIX if it remains open with a Fedora 'version' of '7'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version prior to Fedora 7's end of life. Bug Reporter: Thank you for reporting this issue and we are sorry that we may not be able to fix it before Fedora 7 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora please change the 'version' of this bug. If you are unable to change the version, please add a comment here and someone will do it for you. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete. If possible, it is recommended that you try the newest available Fedora distribution to see if your bug still exists. Please read the Release Notes for the newest Fedora distribution to make sure it will meet your needs: http://docs.fedoraproject.org/release-notes/ The process we are following is described here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping
Penelope, ping?
Penelope, can you please have a look to comment #2 whether it solves your issue or not?
Hi.. sorry for the long delay. I changed the lines to say $Features{'Virus:CLAMAV'} = ('/usr/bin/clamscan' ne '/bin/false' ? '/usr/bin/clamscan' : 0); $Features{'Virus:CLAMD'} = ('/usr/sbin/clamd' ne '/bin/false' ? '/usr/sbin/clamd' : 0); and it worked.
It's a production machine, so I'm unable to test putting those lines into /etc/mail/mimedefang-filter in case it doesn't work. Thanks

Fedora 8 changed to end-of-life (EOL) status on 2009-01-07. Fedora 8 is no longer maintained, which means that it will not receive any further security or bug fix updates. As a result we are closing this bug. If you can reproduce this bug against a currently maintained version of Fedora please feel free to reopen this bug against that version. Thank you for reporting this bug and we are sorry it could not be fixed.
