HOWTO: Upgrade layer1 MailScanner

[chirpy]

Hi,

I recently upgraded our MailScanner installations to the latest version (MailScanner-4.32.5-1). The following procedure is for use after having used the http://layer1.cpanel.net mailscanner add-on.

You use the following completely at your own risk. Don't come running to me if it breaks everything!

/scripts/perlinstaller Net::CIDR
/scripts/perlinstaller Archive::Zip
/scripts/perlinstaller Compress::Zlib
/scripts/perlinstaller Convert::BinHex

wget http://www.sng.ecs.soton.ac.uk/mailscanner/files/4/tar/MailScanner-install-4.32.5-1.tar.gz
tar -xzf MailScanner-install-*.tar.gz
rm -Rf /usr/mailscanner.new/
rm -Rf /usr/mailscanner.old/
cd MailScanner-install-*/perl-tar
tar -xzf MailScanner-*.tar.gz
mv -f MailScanner-*/ /usr/mailscanner.new
cd ../..
rm -Rf MailScanner-install-*
cd /usr/mailscanner/etc/
mv -f MailScanner.conf.new MailScanner.conf.old # MailScanner.conf.new may not exist, don't worry about it
cd reports/en
mv -f languages.conf.new languages.conf.old # languages.conf.new may not exist, don't worry about it
cd /usr/mailscanner.new/etc/
mv -f MailScanner.conf MailScanner.conf.new
mv -f virus.scanners.conf virus.scanners.conf.new
cd reports/en
mv -f languages.conf languages.conf.new
cd ../..
cp -Rf /usr/mailscanner/etc/* ./
mv -f virus.scanners.conf.new virus.scanners.conf
cd reports/en/
mv -f languages.conf.new languages.conf
cd /usr/mailscanner.new/
find ./ -type f | xargs replace "/opt/MailScanner/" "/usr/mailscanner/" --
cd etc/
../bin/upgrade_MailScanner_conf MailScanner.conf MailScanner.conf.new >  MailScanner.new
mv -f MailScanner.conf MailScanner.old
mv -f MailScanner.new  MailScanner.conf

At this point you should edit MailScanner.conf and make any modifications that you want to new settings added by the upgrade.

Then:

cd /usr
killall MailScanner
sleep 8  # then wait a few seconds for it to stop
mv -f mailscanner mailscanner.old
mv -f mailscanner.new mailscanner
/usr/mailscanner/bin/check_mailscanner
tail -f /var/log/maillog

That last command is to watch the maillog file for any errors. Then test.

If you have any problems, or would prefer someone with experience to do this for you, we offer a cheap package for this service:

Thanks for the How To. I got this to work with a couple modifications. I had to install:

Net::CIDR
Archive::Zip

Also, this command:

cp -Rf /usr/mailscanner/etc/* ./

overwrote the new virus.scanners.conf file with the old one, which is in the wrong format. I uncrunched the archive again, copied the new version into the new directory and ran this command again:

perl -pi -e "s/\/opt\/MailScanner/\/usr\/mailscanner/g"  /usr/mailscanner.new/etc/virus.scanners.conf

After adding the missing Perl modules and fixing the virus.scanners.conf file the updated MailScanner started right up and seems to be working fine.

Hi FWC,

Thank you for that. I've updated the howto with the steps you've mentioned. Oddly my installation already had both the perl compression libraries (RHE3.0 perl 5.8.1).

I did it on a 7.3 box that didn't have them. I have an RHE one I haven't updated yet. Everything is working fine and I'll be updating them all tonight. Thanks again.

Jonathan,

get the following lines in /maillog..... any ideas what's gone wrong?! ;-)

Looks like you missed out some of this bit:

cd /usr/mailscanner/etc/
mv MailScanner.conf.new MailScanner.conf.old # MailScanner.conf.new may not exist, don't worry about it
cd reports/en
mv languages.conf.new languages.conf.old # languages.conf.new may not exist, don't worry about it
cd /usr/mailscanner.new/etc/
mv MailScanner.conf MailScanner.conf.new
mv virus.scanners.conf virus.scanners.conf.new
cd reports/en
mv languages.conf languages.conf.new
cd ../..
cp -Rf /usr/mailscanner/etc/* ./
mv virus.scanners.conf.new virus.scanners.conf
cd reports/en/
mv languages.conf.new languages.conf

You can recover it by downloading the tar.gz file again, then open it up and go to the directories in this distribution for languages.conf and then virus.scanners.conf and copy those new files over the top of the ones now in your /usr/mailscanner/etc/ directory tree.

Let me know if you want more specific instructions.

ok, fixed that, but now have....

Mar 8 10:55:16 dennis MailScanner[12974]: Can't run commercial checker clamav ("/opt/MailScanner/lib/clamav-wrapper"): No such file or directory

[chirpy]

Need to run this:

perl -pi -e "s/\/opt\/MailScanner/\/usr\/mailscanner/g"  /usr/mailscanner/etc/virus.scanners.conf

[hostseeker]

I got the following errors when I tried to start MailScanner after going through the outlined upgrade process:

Starting Mailscanner...
/usr/mailscanner/bin/check_mailscanner: line 112: cd: Sr/mailscanner/bin: No such file or directory
/usr/mailscanner/bin/check_mailscanner: line 113: MailsScanner: command not found

I repeated the process and got the same error. I had installed MailScanner from layer1 about 1 month ago and it was working fine..

Any ideas?

[chirpy]

It appears that you may have mis-typed the per substitutes or something.

If you edit /usr/mailscanner/check_mailscanner lines 44 to 46 shouls read:

process=MailScanner
msbindir=/usr/mailscanner/bin
config=/usr/mailscanner/etc/MailScanner.conf

What do yours?

[hostseeker]

Mine showed:

process=MailScanner
msbindir=Sr/mailscanner/bin
config=Sr/mailscanner/etc/MailScanner.conf

I corrected them as you stated, however it still isn't working I think the problem has something to do with the very first line of the /usr/mailscanner/bin/MailScanner file.

What should the first line be?

[chirpy]

That should read:

#!/usr/bin/perl -I/usr/mailscanner/lib

It does sound like the search and replace didn't work right for you. You might find more files with similar problems.

[hostseeker]

Yeah, the first line of mine had Sr/ instead of -I/usr

I fixed that, and started Mailscanner and it seemed to start okay.

However, at this point my email system is completely down and has been since I did this MailScanner upgrade. MailScanner is not running but I can't receive any email. I have restarted Exim and Cpop and the restart worked okay, but no email for the last 2 hours!

Can you give me any ideas as to what might have messed it up and how to fix it?

[hostseeker]

okay apparently I mistyped when doing the upgrade and the search and replace changed some paths. My fault!

If someone could share the proper paths for the following files so I can correct my mistake I will be grateful:

In /usr/mailscanner/etc/virus.scanners.conf

the line for clamav I have:

clamav /usr/mailscanner/lib/clamav-wrapper /u/usr/local

is this correct?

The correct lines are:

clamav          /usr/mailscanner/lib/clamav-wrapper     /usr/local
clamavmodule    /bin/false
