Migration from other control panels / Re: cwp-cwp migration Connection not reached The following error occurred
« on: March 03, 2023, 06:25:47 AM »on new server copy Public Key from: # cat /root/.ssh/id_rsa.pubAnd to be clear, this had no bearing on my connection difficulties. I already had my SSH key pair in place and it was in the authorized_keys, so that was not the issue. I too experienced the "Connection not reached - the following error occurred" error message before running down my solution list. (For sure, it was the standing on the head part that solved it...)
and paste Public key to Old server: # nano /root/.ssh/authorized_keys

Information / Re: need help cwp-->cwp
« on: March 03, 2023, 05:26:56 AM »
I am going to duplicate post this solution here, in case it helps someone searching for the answer.
In order to succeed at a CWP->CWP migration, you have to stand on your head, pat your belly, and rub your feet at the same time in order to make this work. Actually, I just had the opportunity to do a CWP -> CWP migration, so here was my solution:
Disable the firewall (CSF & LDF) on both origin and receiving servers.
On both servers, reset the r00t password to be 8 characters or fewer.
In
On the receiving server, use the interface in User Accounts > CWP->CWP Migration.
After successfully migrating the accounts, revert all changes to your SSH configuration, restart sshd, reset the r00t passphrase to strong ones, and re-enable the firewalls.

Backup / Re: New Backup Error
« on: February 13, 2023, 09:46:17 AM »
Not to be snarky, but the New Backup is labeled as "beta" for a reason... I would expect to encounter some bugs along the way until it is fully shaken out!

You can set message throughput limits under the Packages > Packages menu item (don't you love the redundancy there?).
It is set under the Hourly Emails setting.

I can confirm (testing against 3 CWP servers) that an nmap ping probe (example above) will not set off the CSF firewall. You won't block yourself by doing so.
Code: [Select]

« on: February 13, 2023, 09:12:42 AM »
curl and wget can get a lot, and many offline web readers can suck down a whole site and localize the HTML. So not much you can do about it.

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:
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:
check the buffer pool section, memory allocated for buffer_pool and related caches)
Temporary tables in RAM
Find all in-memory tables by running
Prepared statements, when it is not deallocated (check the number of prepared commands via deallocate command by running

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

MySQL / Re: virtual memory size
« on: February 10, 2023, 08:07:37 AM »
Check the available RAM on your server:
Check mysql configuration: /etc/my.cnf or in the configuration directory: /etc/my.cnf.d.
Run
Do you have a lot of caching in your my.cnf file?
Code: [Select]
free -g
cat /proc/meminfoCheck 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?

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.
