FTP / Re: ftp fails to list unless ip manually whitelisted in firewall
« on: March 05, 2021, 02:04:46 PM »
FTP doesn't just use a single port (e.g. 2248 in your example), it uses this port only for sending commands to the server. The actual data is sent and received over a range of separate ports. That's what you set via PassivePortRange. However, you cannot use the same port for the data and for the commands. So use something like this instread:
PassivePortRange as 30000 35000
Then you also need to allow this same port range (30000-35000) as incoming TCP ports in your firewall. This is not a security risk, the FTP server will open a port in this range just for the transfer, send or receive the data, and then close the port.

CentOS 7 Problems / Re: Too many system updates
« on: November 25, 2020, 04:43:18 PM »
These system updates are provided by Centos and not by CWP. They are regular Linux security updates, and usually don't cause any problems.
Here is what I do when I get such a notification:
1. Wait at least one day, so updates causing major problems could be revoked/replaced
2. I run a copy of Centos 7 with CWP in Virtualbox in addition to my live server. This way I can install and test updates in there before I have to apply them to my main server. Sadly I can only use CentOS Web Panel free in Virtualbox because it's not reachable from the Internet.
3. After updating, I run the following command from a terminal:
needs-restarting -r
to check whether one of the updates requires a reboot. If necessary, I restart the system via Centos Web Panel.
4. I test all the services I normally use in the virtual machine.
5. Once I'm sure the updates have no negative side effect, I apply them also to my main server.
Btw, I have already tested and applied these new updates.

Information / Re: CWP Secure CentOS Kernel
« on: October 21, 2020, 02:36:23 PM »
Is there a way to remove this warning? I'm the only user of this VPS running CWP, but I run multiple domains which I admin via CWP. I don't have any needs for a secure kernel.

Updates / Re: Updating Apache to current version?
« on: October 09, 2020, 01:56:52 PM »
Just a small notification that 2.4.46 is available now via:
WebServer Settings- Apache Re-Build.
I have just installed it and it seems to work fine.
Thanks!

Updates / Updating Apache to current version?
« on: August 27, 2020, 08:36:28 AM »
Currently CWP is offering Apache 2.4.41 on the page "Apache Re-Build", which has been released more than a year ago on August 14, 2019.
I'm worried about security flaws in such an old Apache version, there have been a lot of security updates since then:
https://www.apachelounge.com/Changelog-2.4.html
Is there a way to install a newer Apache manually without damaging the rest of CWP?

E-Mail / postfix fails to start after yesterday's update
« on: February 20, 2020, 09:43:07 AM »
Hi!
After yesterday's update:
postfix.x86_64 2:3.4.7-1.el7 cwp
Postfix fails to start here:
systemctl status postfix.service returns the following two errors:
After a rollback of the last yum update, it works again. Rollback via:
yum history
then check what the newest ID is, and then
yum history undo <ID>
This returned to postfix-2.10.1-7.el7.x86_64, which is quite a big version jump.
I guess that Postfix 3.4.7 requires a different configuration than Postfix-2.10.1.
Any ideas how to find out what's going wrong? The logs don't tell me what queue directories couldn't be created.
Here are the changes I made to the default postfix configuration to use procmail to filter and deliver mails:

CentOS-WebPanel GUI / Re: Does "CWPpro Terminal" work for you?
« on: July 16, 2019, 09:38:35 AM »
I have a valid Hostname with A record DNS and ssl, and the normal CWPro admin panel shows up just fine. The "CWPpro Terminal" loads without any error messages, but the page is blank with a white square the size of a single character in the upper left.

1c) I have now also tried with Internet Explorer 11: The "CWPpro Terminal" doesn't work either. The "SSH Java console" fails to launch due to an invalid signature of the applet jcterm-0.0.10.jar located at
admin/design/3rdparty/sshterm/jcterm-0.0.10.jar.
jarsigner.exe -verify jzlib-1.1.1.jar reports:
Warning:

This jar contains signatures that does not include a timestamp. Without a timestamp, users may not be able to validate this jar after the signer certificate's expiration date (2014-07-18) or after any future revocation date.

I wonder what are the requirements for "CWPpro Terminal":
1. Does it require Java? I ask because there is a menu entry in "Service SSH" named "SSH Java Console", and it doesn't work either. To my knowledge, modern browsers no longer support Java. Here is a test page:
https://java.com/en/download/installed.jsp
a) In Firefox, I get "We have detected you are using the 64-bit version of Firefox which will not run the Java plugin."
b) In Chrome I get "The Chrome browser does not support NPAPI plug-ins and therefore will not run all Java content. Switch to a different browser".
2. Does it matter that I changed my SSH port (due to the many hacking attempts to port 22)? The "SSH Java Console" page allows to set the port and correctly shows the one I use, though.

Well, I have waited for an hour now after entering user name and password, but nothing happened. I used user "root" for login. I also tried a non-root user, but then I got an error.

CentOS-WebPanel GUI / Does "CWPpro Terminal" work for you?
« on: July 12, 2019, 10:26:45 AM »
When I click on the "Terminal" button at the top in CWP Pro (paid version), I get a submenu with two options:
"Simple Terminal"
"CWPpro Terminal"
"Simple Terminal" opens a terminal just fine in a new tab, without asking again for the password. However,
"CWPpro Terminal" doesn't seem to work with Chrome or Firefox:
- it asks again for the user name and password
- once I enter them, I get a black screen with a tiny (about one character) white square in the upper left corner
I have tried disabling Noscript on that tab, but that didn't make any difference.
Maybe I need to install some additional packages via yum to make this work?

Updates / Re: Checking for new Apache or PHP versions via command line?
« on: April 08, 2019, 04:32:46 PM »
Interesting, I just got this update via Yum manager:
cwp-httpd.x86_64 2.4.39-1 cwp
After installing, the page "WebServer settings" - "Apache rebuild" shows:
Server version: Apache/2.4.39 (Unix)
Server built: Apr 5 2019 10:19:42
Although 2.4.39 isn't even available under "Select NEW Apache version:".
So at least we got the security update now, thanks CWP support!

Hi!
Do you think it could be done via a paid custom module, e.g. a module which sends an e-mail when a new Apache build is available?

Updates / Checking for new Apache or PHP versions via command line?
« on: March 19, 2019, 02:03:18 PM »
Is there a command to check whether there is an update of Apache and/or PHP available in CWP?
Apache:
Currently I have to go to CWPro Admin - WebServer settings - Apache Re-Build, and open the combobox there to check whether these is a new Apache version. The latest Apache is 2.3.38 since January, but CWPro only has 2.3.37 - I'm a bit concerned about security.
PHP:
Here I have to go to CWPro Admin - PHP Settings - PHP Version Switcher, and also open the combobox. PHP is up to date in CWP.
I would prefer a command line check, so I could write a cron script which warns me when a new version gets available. Checking manually every day is tiring.
