***** FATAL: Failed to download updatenow.static from server: The system cannot update the /var/cpanel/sysinfo.config file. at /usr/local/cpanel/Cpanel/GenSysInfo.pm line 115.

While trying to upgrade cpanel  to new version was getting error

FATAL: Failed to download updatenow.static from server:

The issue was due to corrupt RPM

I used the below fix to resolve this issue



mkdir /root/old_rpm_dbs/


Now move the original RPMs to the new folder


mv /var/lib/rpm/__db* /root/old_rpm_dbs/


Finally rebuild the RPM database


rpm --rebuilddb


Now you can force an update of the cPanel server and it should work again.


/scripts/upcp -force



					

		
		
	

							
	

				

			
						

				Failed to connect 1006  VNC virtualizor
			

								


				

			
While working on one of the nodes which has Virtualizor Software was facing issues accessing VNC . giving error failed to connected 1006


The issue was due to Virtualizor upgrade


Below is the command you need to execute to kill all process using below command for VNC to work


[root@os1126 ~]# kill $(pgrep -f “/usr/local/virtualizor/enduser/themes/default/novnc/utils/websockify”)

[root@os1126 ~]# kill $(pgrep -f “/usr/local/virtualizor/enduser/themes/default/novnc/utils/websockify”)

kill: usage: kill [-s sigspec | -n signum | -sigspec] pid | jobspec … or kill -l [sigspec]


Now after retrying accessing virtualizor I can see it working fine

					

		
		
	

							
	

				

			
						

				“chown: Invalid username: root:Disk”
			

								


				

			
The server was not allowing login to server even when ssh keys were saved


On rebooting server I could see it and error on screen “chown: Invalid username: root:Disk”


On troubleshooting found error to be due to corruption of /etc/passwd  as this is where all users are saved and due to corruption the user  root was missing in  /etc/passwd


So I got the serve in single user mode and fastboot as only single user mode wont server and would restart


Once I got access to single user I just moved the /etc/passwd to /etc/passwd.bkp and  copied  /etc/paswd.OLD which was in  /etc to /etc/passwd


Now on rebooting server i can see it working fine. 🙂

					

		
		
	

							
	

				

			
						

				Parse html as PHP is easyapache 4
			

								


				

			
 


Normal rule in .htaccess to parse html files as php on easyapache 3 are not working on easyapache 4


#AddType application/x-httpd-php .php .htm .html


#<FilesMatch “\.(htm|html|php)$”>

#SetHandler application/x-httpd-php56

#</FilesMatch>


 


Below is the code which will need to be added In cpanel, multiphp manager will add the following for force a specific

version of php:


# php — BEGIN cPanel-generated handler, do not edit

# Set the “ea-php54” package as the default “PHP” programming language.


AddType application/x-httpd-ea-php54 .php .php5 .phtml


# php — END cPanel-generated handler, do not edit


Make sure the AddType and the selected php version matches! So there we go, simple when you know how.


 


 

					

		
		
	

							
	
							
	

				

			
						

				DNS error bad owner name (check-names) /tmp/cpanel
			

								


				

			
While working with one client I was getting below error in DNS


DNS error bad owner name (check-names) /tmp/cpanel


So I went ahead and checked DNS zone file using below command


 


root@vps [/var/named]# named-checkzone onlinecsource.com /var/named/onlinesource.com.db

/var/named/onlinesource.com.db:56: _autodiscover._tcp.cheapsalesleads.onlinesource.com: bad owner name (check-names)

/var/named/onlinesource.com.db:57: _autodiscover._tcp.cheapsalesleads.onlinesource.com: bad owner name (check-names)

zone onlinesource.com/IN: loaded serial 2017030209

OK


So the error pointed to line 56 and 57 in zone file


Went ahead and deleted the line 56 and 57 and reload DNS zone file


All works good now


 


 


 

					

		
		
	

							
	

				

			
						

				Sorry, the domain xx.xx.104.in-addr.arpa is owned by another user (nobody)
			

								


				

			
While adding rDNS file in cpanel server I was getting below mentioned error


Sorry, the domain xx.xx.104.in-addr.arpa is owned by another user (nobody)


I have found that at one point in the past this domain was present on this server.


I have removed remnants of the domain from /var/cpanel/users/system and removed references to it from /etc/userdomains and /etc/remotedomains.


I then rebuilt the various caches:


====

/scripts/updateuserdatacache

/scripts/updateuserdomains

====


I am now able to add zone file without any issues


 

					

		
		
	

							
	

				

			
						

				Incorrect DiskSpace and Information in cPanel
			

								


				

			
While working on one clients vps for incorrect disk usage  stats for mails


While the default cpanel has no emails the usage stats showed 750MB.


After going through I found a issue which was causing this


The file causing this issue was maildirsize


maildirsize is the file which shows stats information for each account


root@vps [/home/designse]# find . -iname maildirsize

./mail/designserver.net/gordon/maildirsize

./mail/designserver/gordy/maildirsize

./mail/designserver/auctions/maildirsize

./mail/designserver/homemedia/maildirsize

./mail/maildirsize


I went ahead and deleted the file to fix this issue.

root@vps [/home/designse]# cd mail/

root@vps [/home/designse/mail]# rm -rf maildirsize

root@vps [/home/designse/mail]#


Now all stats shows right details
