Since the update I have a problem with my Firewall. I need to set "Allow all incoming connections" under "Server => Firewall" in order to connect over FTP with TLS (explicit). This was working before the update without allowing all incoming connections. How to fix this in the Plesk panel?
View 2 RepliesWhen I deny all other traffic for the "System policy for incoming traffic" to secure the server by only allowing the explicit ports I've requested to open, my server stops operating correctly.
It appears when I set the "System policy for incoming traffic" to deny, it appears to be disrupting various functions such as web traffic over ports 80/443, FTP, SSH, they either work extremely slow or don't work at all.
I brought this up with my Plesk license provider and they stated that the Plesk firewall doesn't add any tracking for ephemeral ports, therefore if you set the policy to drop for incoming/outgoing, it's not going to allow proper TCP communication since the return socket can't be opened. Also that the firewall is an explicit deny system rather than explicit allow based system.
Am I doing something wrong? All I want to do is to block all ports other than the ones I've set to allow. Is this how it is supposed to work?
I wonder if there is any chance to change the domain that is being shown as the incoming/outgoing mail server to users of the Plesk Panel, when clicking on the "Info"-Icon near an e-mail-account in the mail list (see screenshot).
We only have a SSL certificate for one domain and want our customers to use this domain in their mail client settings, so that the client trusts the domain.

Any method for copying the Firewall (extension) rules from one server to another.
On my plesk server, i have several emails account. These email addresses should receive only emails send by a specific server. But for now, they can receive any email, including spam.
So, i would like to block all emails that are not coming from the allowed server.
How can i do this in plesk ? As i am not a very good server admin, can you tell me exactly what i need to do in plesk?
I am having trouble connecting to my ssh server. It responds with a lengthy error message about no network etc. but it is the last message that concerns me:
Sometimes, such troubles can be caused by a misconfigured firewall.
How can I check the firewall if I cannot connect to ssh? I am running plesk 11.5 control panel and CentOS 6. Is this something I can do from plesk?
I can see that the firewall in plesk is set to allow all for ssh, but I cannot see way to disable the firewall to test ssh connection. Can this be done from plesk?
I have a client with a dedicated server running. Spec below.
The problem I am having is with incoming email. When I set up a new email account it can take about 10 attempts to log on to the incoming mail server. Once it has connected it will be ok for a short while then I will get a connection error and no emails will come through.
This is happening across all platforms, PC / MAC / iPhone and iPad.
I am a web designer with limited knowledge of the setting up of the server and was looking to set up email server within plesk.

The FTP client connect to my server, but listing content times out. After allow other traffic the content get listed. The rule "Allow FTP connections" ist in all enabled all the time.

My server started lagging up and I processed my configserver firewall logs and founds tons of TCP out connections. How can I track down which user was making these connections, if possible?
I have a virtuozzo VPS with CSF. People can't connect to ftp because the firewall is conflicting with iptables. I looked at the csf guide:

To correct it, the ftp issues states:

For example, with pure-ftpd you could add the port range 30000:35000 to TCP_IN

how to use Plesk through “Customer's Guide, Plesk 12.0” manual from Odin website. I have a VPS Cloud plan at OVH with Plesk 12 Web Admin + CentOS 6.6
I wish to know how to enable POP3, IMAP, SMTP, FTP protocols with a cryptid connections using native Plesk/CentOS certificate (not purchasing one but self-made by the server). Moreover, I wish to know if it uses SSL or TLS.
URL....We are running Plesk 12 on a Linux VPS where we have multiple domains running.Multiple of these domains should redirect from www. domain name. ext to https://ext.domainname.com.This is configured with the Domain forwarding in Plesk, with hosting type Forwarding.But as described in the 2 links provided above, whenever you go to https://www.domain.ext, it does not redirect, and actually shows a Security error, since the domain doesn't have the SSL-certificate installed (because it should redirect to the https://ext.domainname.com).
Clearly we don't want visitors on the website to receive the (incorrect) Security error, and we want all traffic to http(s)://www.domain.ext to be redirected to the appropriate subdomains. allows us to redirect both the https/http connections to the domains, without forcing us to have the domains have a Website hosting add redirect them manually with (for example) .htaccess.
How to activate/enable the firewall by cli, does this is possible?
Firewall module is installed.
Option in plesk GUI working well.
Does this is possible ? If yes how ?
Is that possible to block baidu without specifying whole list of IDs it's using ?
View 1 Replies View RelatedI have these problems since version 11.5. Now I have installed version 12 on centos . FTP works fine and is super fast and speedy until i enable PLEK FIREWALL, I also tried to add passive port range 60000-65534 to Plesk Firewall rules.
But nothing works.
It takes like 10 times longer to Login + List Files + Make changes using FTP. We applying changes via FTp and its very slow. We can use plesk file manager but its very inconvenient way for quick file uploads and changes.
I already posted this as a bug report and now wanted to inform other users.
Starting with Plesk 11.5, the file "/opt/psa/var/modules/firewall/firewall-emergency.sh" contains the following line:
Code:
rm -f /opt/psa/var/modules/firewall/active.flag
That line stems from updating
Code:
Preparing to replace psa-firewall 11.0.9-debian6.0.build110120608.16 (using .../psa-firewall_11.5.30-debian6.0.build115130819.13_amd64.deb) ...
Unpacking replacement psa-firewall ...
Now, when you stop the firewall, you cannot start it again, cause deleting the active.flag disables the firewall:
Code:
# ll /opt/psa/var/modules/firewall/active.flag
-rw-r--r-- 1 root root 0 2013-11-26 09:22 /opt/psa/var/modules/firewall/active.flag
# /etc/init.d/psa-firewall stop
psa-firewall: firewall successfully disabled
# ll /opt/psa/var/modules/firewall/active.flag
ls: cannot access /opt/psa/var/modules/firewall/active.flag: No such file or directory
# /etc/init.d/psa-firewall start
psa-firewall: service is disabled
You then have to manually "touch" the active.flag to be able to start the firewall again. A workaround is to remove the line:
Code:
sed -i 's:rm -f /opt/psa/var/modules/firewall/active.flag::' /opt/psa/var/modules/firewall/firewall-emergency.sh'
I really hope that Parallels fixes this asap, as normally you won't notice that the firewall is not active when every works fine (nothing is blocked) and Plesk still shows all the rules.
I currently have the Web Application Firewall (ModSecurity) installed but would like a visual interface to block IP's, subnets etc.. Can I install the Plesk firewall as well without any conflict with the Web Application Firewall?
View 3 Replies View RelatedI have a brand new and fresh installed server with:

My Problem is, every day i have to click on activate in the settings of the firewall. Otherwise i have no Mail. The rest (Hosting, etc.) works fine.
No changes in the firewall settings where made, just a migration from my old server.
Plesk Firewall has no effect on IPv6?
I am writing today regarding the Plesk Firewall. It seemed to be pretty handy for quickly blocking troublesome users from *replace-with-whatever-IP-block-is-giving-you-trouble*. Yet I am unable to block IPv6 addresses, and the fire wall seems to let some blocked IPv4s right in. I did not see any distinction as to v4 or v6 in the Firewall dialog for adding custom rules, so...
The question is...
(1) Is the Plesk Firewall *supposed* to apply rules to IPv6 by default?
If yes...
(2) Is there a setting or a switch that has to be configured for this to work?
If yes...
(3) Where are said configuration options located?
Okay, when I run /sbin/ip6tables -L (CentOS) I get output that resembles the iptables (no 6) output, only... what, converted to IP6? Not sure. Example output:
DROP tcp ::ffff:31.0.0.0/104 ::/0 tcp dpts:1:10000
In that particular instance I added a drop for the 31.0.0.0/8 block (using the Plesk Firewall interface), in order to create the script that's loaded into iptables (and ip6tables as well, apparently) when one elects to "Apply Configuration". It worked great, executed perfectly, and the iptables output list output looked to be (and remember, I have grossly insufficient background knowledge in this area) accurate.
Yet at the time of this writing I can see via live traffic monitor that an address in the 31.0.0.0/8 block (IPv4) is pounding away at a website. This is curious, as the live traffic monitor indicates an IPv4 address. So... can an IPv4 address be detected and recorded from a host that is only able to connect via IPv6? While an interesting question, I was more concerned with just blocking the IPv6 address and get more academic with it later.
But this raises another question; why would Plesk populate ip6tables and not provide an interface to actually submit IPv6 addresses.
When I modify rules using the firewall panel it is not generating rules correctly when selecting allow from selected sources deny from others.

What causes the firewall to change / reset itself periodically? I enabled the plesk firewall, but some time later it is reset itself and switched to the opensuse firewall (completely different rule set, which blocks most of the ports).
I then disabled the plesk firewall and loaded my own iptables rule set via iptables-restore command. However a few hours later, it also gets reset to the opensuse firewall. The std. opensuse firewall closes most of the ports, so then our email is blocked.
I would like to permanently switch off any plesk handling of the firewall and manage the iptables myself. How to do this?
I also have fail2ban running and defined my own jail.local files.
Applying Plesk firewall changes? I make my change, apply and get to:
Status: Applying in progress. If your browser shows connection error messages, or if this screen does not disappear in more than 30 seconds, go to previous page.
And there things stay. Going back to look at the firewall I can see the change haven't been applied, and going to apply just results in the same. No error, just no anything. It also took numerous attempts to get firewall modification to be swtich on although finally at about the eighth attempt changes were enabled. Only now I can't apply them ...
After upgrading to Plesk 12 the FTP connection has become very slow. Mode Security, Fail2Ban and Plesk Firewall have been enabled, the security is set to force sFTP and maximum security and in /etc/proftpd.d/ a conf file has been added to set the passive ports that have been opened in the Plesk Firewall (60000 to 62000)
Turning off the Mod Security does not solve the slow connection.
What can we do to detect the cause of the problem?
I have enabled modsecurity system and in 1 day the modsec_audit.log file has grown to more than 700Mb. Is there any way to reduce the number of messages that this module logs?
View 4 Replies View RelatedI am using the plesk firewall and trying to set up SSH rule which only allows from my IP but deny from everywhere else. In previous versions this worked fine by adding an ip selecting Allow from selected sources, deny from others and the icon in the rules would be orange with the lines
allow incoming from xxx.xxx.xxx.xx
Deny incoming from all others
However this no longer works as the deny from all others is not appearing and is not being generated in the iptables by plesk.
