Clamd::ERROR:: UNKNOWN CLAMD RETURN ./lstat() failed: Permission denied. ERROR :: /var/spool/MailScanner/incoming

Is anyone seeing this error in the /var/log/maillog. It's obviously a permissions error, but I can not figure out how to get rid of it.

the /var/spool/MailScanner/ is created by postfix. I tried adding clamav to the postfix group as well as www and wheel the error still occurs.

marcelloc

clamd should be running with postfix user.

Try to apply maiscanner config and check in /usr/local/etc/clamd.conf what user is configured.

Multiple installs all installed

postfix->mailscanner->dansguardian

I check them all all have

Run as another user (clamd must be started by root for this option to work)

Default: don't drop privileges

User clamav

Tried save mailscanner configuration and enabling and disabling the daemon. It appears that the program is not updating the clamd.conf at all.

Did a new clean install -postfix-mailscanner-dansguardian. Saved the mailscanner config and checked the clamd.conf "clamav" was still the user.

Manually edited the clamd.conf and changed the user from "clamav" to "postfix" reboot and everthing is working properly.

@mschiek01:

I'll check again the code and include a force config file option. On my install it's working with user postfix without any manual edit.

I have a problem with Mailscanner, mailscanner installed today so it should be uptodate.
Working with postfix and mailscanner-dev: http://forum.pfsense.org/index.php/topic,40201.0.html

Mailscanner do exit every second or two. with this in the log:
mailscanner: Process did not exit cleanly, returned 1 with signal 0

I also get this in the log:
ClamAV Module ERROR:: Could not load databases from /var/db/clamav

So i tried to do as suggested here and tried to run this:
/usr/local/bin/freshclam

but then i got this error:
ERROR: Can not open /var/log/clamav/freshclam.log in append mode (check permissions!)
ERROR: Problem with internal logger (UpdateLogFile = /var/log/clamav/freshclam.log)

When i check the folder /var/log/clamav it is emty!!
Same thing with /var/log/db emty!!

Running freshclam –version
Gives ClamAV 0.97.3

and did run this one(/usr/local/bin/sa-update ) too and that did run with no output.

So is mailscanner restarting every second because clamav has no db??

EDIT: Might have been a bit quick posting here.

Manually created the log file: /var/log/clamav/freshclam.log and changed permisions so any thing could log to it.
then tried to updated and then it complained it could not create tem folder in /var/db/clamav so i changed the permisions on that folder so it could update and create the temp folder.

And now i am stuck on this error when trying to update clamav:

WARNING: Clamd was NOT Notified: Can't connect to clamd through /var/run/clamav/clamd.sock
connect(): No such file or directory ???

The folder var/run/clamav/ is emty? Should it be?
And now mailscanner is veining me this in the log
mailscanner: Process did not exit cleanly, returned 0 with signal 9
And i get alot of this: kernel: swap_pager_getswapspace(4): failed until i get this: kernel: pid 8874 (perl5.12.4), uid 125, was killed: out of swap space
And then it continues with: swap_pager_getswapspace(5): failed

Sorry for noob questions. ::)

marcelloc

Did you configured the mailscanner on gui? Checked and save options on all tabs?

Unubtanium

jupp i did.
I did go through all of the to make sure they saved and did write the config files to stop this error:
MailScanner[15521]: Syntax error in line 145, value "" for allowscripttags is not one of allowed values "yes","disarm","no"

that did not fix it so i had to change allowscripttags from disarm to no..

looks like the swap_pager_getswapspace problem is gone after a reboot.. strange???

Looks like thing are working as they should now, and did not do anything else then describe in previous post except reboot.

But anyway would still like to know more about this error:
WARNING: Clamd was NOT Notified: Can't connect to clamd through /var/run/clamav/clamd.sock
connect(): No such file or directory

check this file /usr/local/etc/clamd.conf

scroll down to the following line and make sure that this is who clam is running under:

Run as another user (clamd must be started by root for this option to work)

Default: don't drop privileges

User postfix

If not change the user then you will need to reboot the box.

Unubtanium

Thanks for that mschiek01, the user was set to clamav so just changed it(Nice recap with the VI editor too :) ) and now it is rebooting.

So now more playing with subject word blacklisting. ;D

Just a question, did you checked VirusScanning(yes) and Virus scanner =clamd on mailscanner antivirus tab?

I've checked the code and it looks for user clamav on clamd.conf file


#check virus_scanner options
$libexec_dir="/usr/local/libexec/MailScanner/";
if ($virus_scanning == "yes"){
	if ($antivirus['virus_scanner'] =="none"){
		unlink_if_exists($libexec_dir.'clamav-autoupdate');
		unlink_if_exists($libexec_dir.'clamav-wrapper');
	}
else{
.
.
.
#clamd conf file
$cconf="/usr/local/etc/clamd.conf";
if (file_exists($conf)){
	$cconf_file=file_get_contents($cconf);
	if (preg_match('/User clamav/',$cconf_file)){
		$cconf_file=preg_replace("/User clamav/","User postfix",$cconf_file);
		file_put_contents($cconf, $cconf_file, LOCK_EX);
		}

All my boxes had virus scanner = auto. Maybe that is why I always have to configure it manually?

Maybe you should default it in your package to clamd instead of auto?

@marcelloc:

I just checked an it was set to:
VirusScanning(yes) ~~Do not even know how to change this or turn on any options that have (no)Guess i have to modify some config files or something. Google will answer me i hope. ;D~~ Aha ()=default and if it is selected it is on right?

Virus scanner was set to auto

So what is recommended i do?
Change user back to clamav and set it to use clameav?
And should i be able to see in the logs that any emails is scanned and passes the scan?
Reason for asking is that i can not see anything like that in the log files in regards to avscan of emails..
This is what i see in the log for an incoming email:

@mschiek01:

The php code checks for virus_scanning == "yes" and 'virus_scanner' != none

so auto or clamd will result on the same config check.

Leave the user as postfix or it will not work.

in /var/log/maillog you should see something like this on accepted mail.

First though you need to configure postfix to hold the mail in the que so it can be scanned with something like this.

in the gui for postfix
click the access lists tab
and put something like this "/^from:/ HOLD"

You also need to configure the recipients tab as well as the antispam tab

If you look to the botom of the antispam page:

Check use third party anti spam
I use message hold mode "manual mode using acls"
mailscanner+spam assassin + clamav

The package works great once you get it set up.

Marcelloc helped me a lot. Just trying to return the favor.

Just any FYI. If you are going to use active directory to extract your valid recipients. You need to make sure you install p5-perl-ldap.

Your help is highly appreciated, and if i can help any1 i will do the same. ITs what it is all about. Love sharing knowledge.
Thanks for heads up on the ldap. This will be something i will be using on a late time when i have get enough know how on this packages.
