GTAlex: Blog about real work with servers and spam protection
Many people are looking for information on setting up complex systems, and the gtalex website. ru just for such people. This is not just a placeholder page, but a living resource where the author shares his experience. There are no empty promises here, only specifics from the practice of system administration and web development. The author, apparently, is an experienced person who has encountered various problems on servers.
One of the main topics of the blog is website protection. The author writes about how AI is now being used by spammers. He gives an example when he received spam created by artificial intelligence in the comments on his resume. The text was similar to the truth, but the link led to someone else's project. This shows that even simple comments now require attention to detail to avoid falling for scammers.
Problems with CMS Bitrix and CentOs
A significant part of the content is devoted to working with the 1C-Bitrix platform. The author analyzes in detail situations when sites crash or work slowly. For example, he described the case of restoring a website based on Aspro Bitrix. There were a lot of backdoors and all sorts of slag, although the engine itself was updated. This is an object lesson for owners of such sites - you need to monitor not only the core, but also the modules.
The painful topic of migration from CentOs 7 is also raised. The author expresses bewilderment that Bitrix did not prepare users for the end of support for this operating system. The text mentions that CentOs 9 is a completely different product, and many search engine queries lead to a dead end. For those who have encountered errors in the Bitrix admin panel, for example, lack of memory with a large list of users, the site has specific commands to correct the situation via the command line.
Security and backup
Security issues are also not ignored. We talk about a vulnerability in OpenSSH (CVE-2024-6387), which allows attackers to gain root access. The author advises urgently updating servers, since millions of machines are at risk. There are also posts about fail2ban - a tool that helps block vulnerability scanners and bots, reducing the load on the server.
Special attention is paid to backups. An example is given of a client whose data was stored on the same server as the main site. If the equipment was physically damaged, everything was lost. Now the author recommends using RClone to transfer data to other media in order to sleep peacefully.
- Subjects:System administration, Linux, protection against viruses and spam.
- Target audience:Webmasters, owners of Bitrix websites, novice system administrators.
- Features:Real cases from life, not theoretical calculations.
Frequently asked questions about site materials
What to do if there is a memory error in the Bitrix admin panel?
If a fatal error allowed memory size appears, most likely there are too many records on the page. You need to log in via php_command_line. php and run a command that will set the page size to 50 entries. This will help unlock access.
Does CentOs 9 exist?
No, the classic CentOs 9 does not exist. The project died, and what we have now is CentOs Stream 9, which is a different system. You should not rely on requests to upgrade to CentOs 9.
How to protect your server from vulnerability scanners?
A good solution would be to install fail2ban. It analyzes logs and blocks IP addresses that often try to scan the system or bots, thereby reducing the load.
Why has spam gotten smarter?
Spammers have started using AI to generate comment texts. They can analyze the content of the article and write a coherent text with their link, which makes spam more noticeable and cunning.
