Thanks! Makes me feel better. I worried these might have been some known malware behavior. fail2ban still has problems; it is running now, in the log I have the following errors: ---- 2024-04-11 06:26:10,253 fail2ban.utils [2504]: ERROR 7f6e05c23270 -- exec: iptables -w -I...

Hi! I run several pretty generic Plesk installations on Strato VMs. Everything is uptodate, but I found some weird security settings in my machines. I run some HTML websites, plenty of Wordpress with minimal plugins, and one Moodle instance. I'm not a great sysadmin, if anyone has...

Sigh, I'm only talking to myself apparently. This s*cks.

This is for a virtual server. I saw some posts suggesting the hoster might get in the way?

1. I have a well working system, if I allow root access for ssh PermitRootLogin yes without any restrictions. As soon as I add Match Address 127.0.0.1 I cannot login any longer using ssh *at* *all*. Not from the outside (as expected) but also not using the Plesk UI using Tools & settings...

Thanks, but slow iptables doesn't seem to be the reason. How can I get help? Our hoster Strato (and the Plesk reseller) has given up too. Thank you.

Thanks for the update. I wiped the server in waiting again and reinstalled Ubuntu 22.04 LTS and Plesk from my hoster. I didn't do anything but the out of the box system and then enabled the firewall. I still get the same problem. The firewall extension's version is 2.0.2-352 The server is a...

Here the message from the UI, suggesting there never was a good configuration (this is a fresh install!) I did not receive connectivity confirmation after applying new firewall configuration, then same happened after I reverted to previous configuration. This means that both new and previous...

I have the same problem. Fresh install Obsidian / Ubuntu 22.04 LTS. Confirming the rules times out for no apparent reason. I have removed and reinstalled Firewall through the UI and using ssh, same effect: Can't enable the firewall.

Thank you. This was indeed the problem. I had misunderstood the flag "Activate mail service on this domain" to enable/disable all mail sending, not just the emails that might get delivered locally. Given my abilities, I'm always worried about the security of our servers. I keep things minimal...

Hi! we use multiple Linux servers with the same hoster and Plesk Obsidian. On one of the servers, email sending does not work. I suspect this line in the logfiles points at the problem Dec 9 23:12:38 xxx postfix-local[102419]: xxx from=<[email protected]>, to=<[email protected]>...

Thanks. I got my admin account back. But why is the xyz account inferior to the hard-coded (?) admin account? It seems reasonable to me to not use a commonly name for an account that every cracker would try to get into.

Hi, I rent a couple of servers from my provider and manage them all through Plesk. All have been recently installed and are uptodate on Linux/Obsidian. On one server, I decided to not use admin as the main administrator account but rather xyz. The xyz account even though set to full...

Stop talking to yourself.

Not sure "how to close" this issue. Not possible because despite the tag it is not an issue in an issue mgmt sense?
