Installation / Re: Thunderbird problem
« on: February 13, 2023, 09:10:59 AM »
Funny thing is that I've seen countless T-Bird IMAP bugs over the years. And yet, Postbox (a commercial Thunderbird derivative, still using the T-Bird mail engine) seems to have fixed those IMAP errors! I never encounter any when I use Postbox, and having bought a lifetime license years ago, I get all updates that have been released. It offers a lot more spit-n-polish than the default T-bird experience.

MySQL / Re: virtual memory size
« on: February 11, 2023, 12:23:28 AM »
Definitely consider doing some MySQL performance tuning. There are scripts you can download that check your environment and offer suggestions for changes in you my.cnf file.

MySQL allocates memory in tons of places. Especially look at table cache
Performance_schema
Run this:
Code: [Select]
show engine performance_schema status
and look at the last line. That may be the cause for the systems with small amount of RAM, i.e. 1G or less

InnoDB
Run this:
Code: [Select]
show engine innodb status
check the buffer pool section, memory allocated for buffer_pool and related caches)

Temporary tables in RAM
Find all in-memory tables by running
Code: [Select]
select * from information_schema.tables where engine='MEMORY'
Prepared statements, when it is not deallocated (check the number of prepared commands via deallocate command by running
Code: [Select]
show global status like ‘ Com_prepare_sql';show global status like 'Com_dealloc_sql'
Welcome to the deep end ;)

or from outside your server network, telnet in to your server, trying ports 25, 465, 587, 110, 143, 995, 993.
Code: [Select]
telnet <server.ip> 25or do a port scan with nmap:
Code: [Select]
nmap -P0 <server.ip>

CSF Firewall / Re: Custom Webpage rather than "not solved"
« on: February 10, 2023, 03:37:45 PM »
The one-liner above should be:
Code: [Select]
cp /etc/csf/csf.conf{,.backup} && csf -u && sed -i 's/MESSENGER = "0"/MESSENGER = "1"/g' /etc/csf/csf.conf ; sed -i 's/MESSENGERV2 = "0"/MESSENGERV2 = "1"/g' /etc/csf/csf.conf ; sed -i 's/MESSENGER_HTTPS_IN = ""/MESSENGER_HTTPS_IN = "443"/g' /etc/csf/csf.conf ; useradd csf -s /bin/false ; csf -ra
And here it is as multiple lines:
Code: [Select]
cp /etc/csf/csf.conf{,.backup}
csf -u
sed -i 's/MESSENGER = "0"/MESSENGER = "1"/g' /etc/csf/csf.conf
sed -i 's/MESSENGERV2 = "0"/MESSENGERV2 = "1"/g' /etc/csf/csf.conf
sed -i 's/MESSENGER_HTTPS_IN = ""/MESSENGER_HTTPS_IN = "443"/g' /etc/csf/csf.conf
useradd csf -s /bin/false
csf -ra

MySQL / Re: virtual memory size
« on: February 10, 2023, 08:07:37 AM »
Check the available RAM on your server:
Code: [Select]
free -g
cat /proc/meminfo
Check what applications are using large amounts of RAM: top or htop (see the resident vs virtual memory)
Check mysql configuration: /etc/my.cnf or in the configuration directory: /etc/my.cnf.d.
Run
Code: [Select]
vmstat 5 5 to see if the system is reading/writing via virtual memory and if it is swapping...
Do you have a lot of caching in your my.cnf file?

MySQL / Re: MySQL Database Server - Failed

Try moving or removing the aria_log_control file, then start mariadb.
Code: [Select]
/var/lib/mysql/aria_log_control

Mod_Security / Re: Mod Security issue? pid 2459:tid 140698774865664
« on: February 10, 2023, 07:41:15 AM »
You're using the OWASP ruleset. I would suggest trying the Comodo rules instead -- it will throw less false-positives; it's not as restrictive and is more beginner-friendly.

MySQL / Re: zero

Some people just click on the "Unread" link and only peruse those (few) threads. To discover more, you have use this link instead:
Click here to try all unread topics.
Or better yet, simply look on the Forum homepage and just scroll the forum list to see if any topics are new or interest you. But you don't see the "child" fora:
Control Web Panel
(So you could make a case for there being too many categories and sub-categories. But it does help for categorization of issues.)

It's possible to do a permanent redirect in the vhost config:
Code: [Select]
<VirtualHost *:80>
  ServerName example.com
  ServerAlias www.example.com

  Redirect permanent / https://example.com/
</VirtualHost>

But a 301 redirect is preferred. In vhost conf or in .htaccess:
Code: [Select]
RewriteEngine On
RewriteCond %{HTTPS} off
RewriteRule ^(.*)$ https://example.com/$1 [L,R=301]

CentOS-WebPanel GUI / Re: How to enable one click login to phpmyadmin

Unless your MySQL password differs from your r00t password... then MySQL r00t does not equal r00t...

Installation / Re: What distro to go for..
« on: February 10, 2023, 07:24:22 AM »
Good, good, good to know! Thanks for the advice, Starburst. I'll be looking at AlmaLinux as my CentOS 7 EOL exit path.

Installation / Re: Rocky Linux 8 too Rocky??
« on: February 10, 2023, 07:22:57 AM »
Rocky Linux has suffered from missing packages, since the pre-release versions.

But ultimately we had to abandon it for AlmaLinux.
Good to know your experience! I trust your impressions. I was leaning toward AlmaLinux anyway, but I think you've swayed me fully to pursue AlmaLinux for my CentOS 7 EOL exit plan!

E-Mail / Re: I can rececive emails, but cannot send any emails
« on: February 10, 2023, 06:35:19 AM »
Can we arrange a time for me to access your computer and access your server to check what it could be?
Sorry, but that sounds rather scary. Maybe we can keep working on it here in the forum, in public view.

Updates / Re: How can update PHP for cwpsrv
« on: February 10, 2023, 06:08:51 AM »
sure, if you want the nuclear option:
rm -rf the roundcube directory, drop the roundcube DB, and disable the webmail portions of your vhost config files.
But you could simply just block :2095 and :2096 in the firewall for now. (But just say NO to plain http:// connections and don't use :2095 anyway!)
