Grasse 1 Posted July 31, 2021 Share Posted July 31, 2021 Hello, I am using CentOS 7 for providing web hosting. I could manage to my webserver but I notice I can't manage a CentOS Server. When I looked, I noticed ESET Management Agent removal on CentOS 7 Server. When I tried to reinstall ESET Management Agent on the webserver, I took an error. I must use remote IP for connection. I can't use the hostname. Thank you. Link to comment Share on other sites More sharing options...
Administrators Solution Marcos 5,257 Posted July 31, 2021 Administrators Solution Share Posted July 31, 2021 If you can't use hostname, there must be a problem with DNS resolution on the machine. Did you try nslookup or dig the hostname? Link to comment Share on other sites More sharing options...
Grasse 1 Posted August 2, 2021 Author Share Posted August 2, 2021 (edited) Hello Marcos Thank you for answer. I noticed my web servers CSF firewall is blocked 2222 connection ports. When I addallow rule, ema connected ep server and I can upgrade this. I think, when I upgrade firewall, I added rules are deleted. The Firewalls are a nuisance.
