Jun 15, 2015Version 12.0.18. Using QMail.
If I attempt to remove even a small message from the mail queue, using the panel interface, the screen grays slightly but nothing happens. If I refresh the screen after several minutes, I'll sometimes get the following message:
"This operation is taking too long. Check the results in a few minutes."
Switching to Postfix eliminated the problem. But with Postfix, all of my Mailman lists (scores of them) broke, so I had to switch back -- and the problem reappeared.

Jul 21, 2014I 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?
Windows Mail Server - How To Clear Queue
Mar 27, 2009i'm running a windows 2003 server to host a number of websites.
unfortunatly it looks like i didn't correctly protect the SMTP mail server
i checked the 'badmail' folder in the inetpub and found there were upwards of 250,000 bounced mails there... some spammers were obviously having a field day with my smtp server...
i've now changed the settings so that realys are only accepted from 127.0.0.1 and anonymous access is now disallowed.
my problem is that when i start up the SMTP server again spam is continuing to be sent out because the Queue folder is apparently full of junk waiting to go out...
i've tried entering this folder but the computer hangs, presumably because there are so many there...
i've tried deleting and renaming the folder but even with the smtp server turned off i get an 'Access Denied' error...
what can i do to flush or empty the queue folder ?
What's The Best Linux Firewall
Jul 10, 2008I have 3 web servers that I need behind a firewall. Right now they're directly connected to the internet, and have little protection. I'd like to build my own Linux router and have done some research but not sure which is the best solution.
The main feature I need is the ability to forward ports based on the destination host header. Most firewall distros only allow you to forward port 80 to one IP address, but I need the router to send to different internal IPs for different sites.
I've looked at IPCOP and Smoothwall express and a few others, but the "free" ones don't seem to do this.
APF Software Firewall For Linux: Should I Use It
Feb 17, 2008I am setting up a web hosting server in a datacenter.
Websites will be powered by Apache, MySQL and PHP.
I will be using CentOS 5 32 bit.
"APF Software Firewall for Linux" is offered as a free option by the datacenter.
Should I use it?
Configuring A Linux Router/firewall
Nov 10, 2008I run a small datacenter, and we are migrating from Cisco to Linux based routers.
This routers should run a firewall, DDOS mitigation rules, CBQ bandwidth limitation, etc..
I know how to mitigate DDOS using tcpdump, also I know how to route..
I just need some advice about the firewall, stopping basic DDOS, fragmented packets, etc..
Should I use APF firewall in this case? Is there a good IPTABLES set of rules I could use?
I'm giving up from Ciscos, as I just discovered there are some UDP packets that can easily break them. I tested it last night, and that was it, nothing secure A few traffic (bogus UDP packets) and the router was down for a few minutes.

Linux Firewall - Filtering Out Zero Length Packets
Aug 13, 2008I run CentOS 5.2 (Sometimes CentOS 4.6). I have been messing around with IPTables, and cannot find out how to filter zero-length packets.
I believe I might need an unclean module. I have already done hours of reading and researching, but I have come up with nothing, for I do not think this is that common.
If anyone could please let me know the commands to use to filter out all zero-length packets, or the unclean module I need to use with IPTables, I would really appreciate it.

Dec 17, 2014I 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.
Plesk 11.x / Linux :: Firewall Might Disable Itself After Updating To 11.5
Nov 26, 2013I 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.

Plesk 11.x / Linux :: Firewall Has Not Effect On IPv6
May 15, 2014Plesk 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.

Oct 25, 2014Running plesk 12.018 on OpenSUSE 13.1
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.
Plesk 12.x / Linux :: Modify Firewall Rules Never Completes
Nov 9, 2014Applying 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 ...
Plesk 12.x / Linux :: FTP Very Slow (with Firewall / Mod Security Enabled)
Jun 26, 2014After 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?

Aug 17, 2014I 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.
