Sounds like the shell tried to interpret a special character in your provided password. I'll see if I can prevent that.

shawniverson wrote: 09 May 2024 10:59 Your problem is likely SELinux, since you changed the path of the quarantine directory. If you look in /var/log/audit/audit.log you'll likely see a lot of denied operations.

Thank you for this hint, I have corrected the SELinux security context as it was not like on my eFav4 box used in production:

Code: Select all

semanage fcontext -a -t mscan_spool_t /var/spool/MailScanner/quarantine

While checking the default SELinux context I have noted difference between eFav4 (CentOs7) and eFav5 (Rocky Linux 9.x):

eFav4:

Code: Select all

[root@IT1MAILGW1 etc]# matchpathcon -V /var/spool/MailScanner/*
/var/spool/MailScanner/archive verified.
/var/spool/MailScanner/incoming verified.
/var/spool/MailScanner/milterin verified.
/var/spool/MailScanner/milterout verified.
/var/spool/MailScanner/quarantine verified.
/var/spool/MailScanner/ramdisk_store verified.
/var/spool/MailScanner/spamassassin verified.

eFav5:

Code: Select all

[root@it1mailgw5 ~]# matchpathcon -V /var/spool/MailScanner/*
/var/spool/MailScanner/archive verified.
/var/spool/MailScanner/incoming has context system_u:object_r:tmpfs_t:s0, should be system_u:object_r:mscan_spool_t:s0
/var/spool/MailScanner/milterin verified.
/var/spool/MailScanner/milterout verified.
/var/spool/MailScanner/quarantine verified.
/var/spool/MailScanner/ramdisk_store verified.
/var/spool/MailScanner/spamassassin verified.

After correction and reboot the status is always as above, but so far it seems to be no functional problem.

Hi
i can see the same on my eFa4 (CentOS7).

Code: Select all

[root@efa4 ~]# matchpathcon -V /var/spool/MailScanner/*
/var/spool/MailScanner/archive verified.
/var/spool/MailScanner/incoming has context system_u:object_r:tmpfs_t:s0, should be system_u:object_r:mscan_spool_t:s0
/var/spool/MailScanner/milterin verified.
/var/spool/MailScanner/milterout verified.
/var/spool/MailScanner/quarantine verified.
/var/spool/MailScanner/ramdisk_store verified.
/var/spool/MailScanner/spamassassin verified.

Just for Info.

Yours

Same here on both EFA4 and EFA5.

Code: Select all

/var/spool/MailScanner/incoming has context system_u:object_r:tmpfs_t:s0, should be system_u:object_r:mscan_spool_t:s0

But never experienced a problem actually? What should not work? Quarantine of virus contained mails? That is seldom and actually gives me always the same error that I can't remember...

This is not an issue. This directory is on a temp filesystem which is why the discrepancy. The eFa SELinux ruleset already handles it accordingly.

Hello!

I would like to test the new EFA 5 and have a few questions:

- Will it be possible to upgrade directly to the stable version
- What are the system requirements for EFA 5 or are they the same as for EFA4?

Thank you!

Hi
i would like to support testing on AlmaLinux9 or Rocky 9.
Can anybody point me to a kickstart location for information how to start ?

Thx

After installing the test version, when the stable version is released you can switch the repo over to the stable version.

The same.

Hi
thanks for the quick reply.

I got it installed on a AlmaLinux 9.4. No issues to install.

Below you find the first issue. Look like clamd went crazy.

I'm getting the same error while installing on alma linux 8 which supposed to be supported with the efa 4 script?

is there a way around this ( by the way also the mysql error is present in my rollout)

markov wrote: 01 Mar 2024 22:03 Hi,

First, greate news and thanks for EFA v5 beta ...
I don't know where to this topic (no EFA v5 Bugs), so I put it here ...

I successfully install EFA v5 on top of Rocky Linux 9.
After initial configuration I type "OK"

and get this errors:

In Rocky Linux 9 all network profiles are stored in "/etc/NetworkManager/system-connections/" and not in "/etc/sysconfig/network-scripts/"

How to go around this ...

Strange i today installed from a AlmaLinux 9 Minimal without issues.
What is didnt touch is the IP configuration inside of eFa-Configure as this was not showing anything.

The rest worked. Besides the more or less frequent clamd crashes.

Did you use a AlmaLinux 8 MINIMAL ?
And i was using testing for the bash script invokation. Did you use dev ?

Posted: **30 May 2024 16:08**

no I used:

eFa4 can be installed on any system you want as long as it supports CentOS 7, CentOS 8, AlmaLinux 8, or RockyLinux 8 and the system is dedicated to eFa4.

curl -sSL https://install.efa-project.org | bash

Posted: **30 May 2024 19:15**

just installed Alma 9 and used the EFA5 script, installation went fine, config script as well

but afterwards the webinterface was accessible once and then it was not reachable anymore also the efa configure menu freezes up when selecting webmin or fail2ban the others I have not tried yet

increased the memory which fixed it

Hi
on eFA5 i have for some whitelisting actions the following effect.

- i select the email i want to whitelist
- i select: Move selected entries to whitelist
- press sent.
and then i have a blank border see attached picture.

4GB is insufficient. clamd plus all the signatures require a lot of memory, which is why we recommend 8GB.

Thx overlooked this in the requirements.

Interesting. The eFa4 is running on my side with 2 CPU and 4GB without any hickup since years.
But will try to upgrade the mem of the vServer.

Hi
the topic around the oom-killer continued to turn around in my head and i started looking around how to limit mem usage for clamd.
And i found this: https://betatim.github.io/posts/clamav-memory-usage/

This seemed to help but it just limited the frequency . So first step taken.
The i had a look into my VPS and i found that there was no SWAP enabled.
So i added 8GB of swap.

Code: Select all

dd if=/dev/zero of=/swapfile bs=1024 count=8000000
mkswap /swapfile
chmod 0600 /swapfile
swapon /swapfile

And added "/swapfile swap swap defaults 0 0 " to my fstab.

Now lets see if this will solve at least my issue.

Just sharing in case anybody has similar issues.

Just did an install on Alma 9 that went fine.

I enabled it as an outbound relay, and sending went fine.

Incoming does not work. I only created a single account, and email is rejected when I replied to the message from that account.

The maillog messge is: 450 4.1.1 <...> Recipient address rejected: unverified address: No user at this address;

I originally had greylisting enabled. I turned it off because I got impatient.

When greylisting was enabled, there were messages in the log similar to:

451 4.7.1 <...> Recipient address rejected: Intentional policy rejection, please try again later (in reply to RCPT TO command))

I turned greylisting back on to see if that helped. It did not.

I can log in as the user from the website.

From root, I did:

mysql
use mailscanner;
select * from users;

Output shows the user and the admin accounts only.

Probably did something dumb, so I guess I'll reload and try again unless someone has a suggestion.

Try turning recipient verification off to see if that helps using eFa-Configure in the console. It is under Mail Settings.

That worked and allows emails to be received. The downside is allowing email from any random user to be received and then rejected by the main server.

Thoughts on the cause?

EDIT: I wiped and did the install with CentOS 9, and things are working fine. Only had an issue with fail2ban not starting because of a missing log file.

yes, postfix doesn't know how to verify the user.

if you want to use user verification, you have to configure postfix so postfix can know which users are valid.

When i use the small script below i can see fail2ban believes it has blocked but nothing is in the ip tabels nor is something visible with the fiewal-cmd.
