We had that problem with SolusVM server while adding a Slave to the master in SolusVM control panel
Here Is What You Need To Do…
In that case you need to check the IP address that is listed in /usr/local/solusvm/data/allow.dat on the slave matches the IP Address of the master. You can check the IP running the below command on your shell
# curl -s http://checkip.dyndns.org/ | grep -o “[[:digit:].]\+”
The result for above command should correct IP address. You need to check one thing the IP address is listed on the eth0
PHP Modules Errors :
SolusVM uses the standard CentOS PHP rpms for its installation so any other version usually breaks the system.
First check the version of php# php –v
If you get any other version instead of 5.1.6 , it usually means you have extra repos installed in yum, like the old lxlabs repo or rpmforge repo. There is no real need to have these extra repos installed on your node and they can be removed from the /etc/yum.repos.d folder.
Any module errors are usually caused by the modules directory being wrongly defined in /etc/php.ini.
For 32bit systems the module directory should be: /usr/lib/php/modules
For 64bit systems the module directory should be: /usr/lib64/php/modules
