Setting up https

[ewong 6]

Hi,

I have followed https://support.eset.com/en/kb7857-set-up-an-https-ssl-connection-for-eset-protect-linux but I'm finding it confusing because the server.xml changes for an Existing Certificate vs. a New certificate are different.

I am creating a new certificate and have changed the server.xml to include the following:

Quote

<Connector server="OtherWebServer" port="8445" protocol="org.apache.coyote.http11.Http11NioProtocol" SSLEnabled="true" maxThreads="150" scheme="https" secure="true" clientAuth="false" sslProtocol="TLS" keystoreFile="/etc/tomcat/tomcat.keystore" keystorePass="yourpassword"/>

After saving, and restarting tomcat,  I still can't use https.  I used iptables to open the port 8445.

Quote

iptables -A INPUT -p tcp -m tcp --dport 8445 -j ACCEPT

That didn't work.  So I changed SELinux to Permissive.

No go.  I took a look at netstat, and 8445 is certainly opened.

Going to https://<ip>:8445/era/webconsole  gives me a timeout error. 

At this point, I'm somewhat stumped.  So i took a look at the tomcat logs and came across:

Which after searching, gave me the result of changing the following:

Quote

<Connector port="8009" protocol="AJP/1.3" redirectPort="8448" secretRequired="false" />

 

I added the secretRequired="false"   and that "fixed" the issue (but from my search, it wasn't a good idea.. but at this point, I just want it to work.

Now I have no idea what to do.  I can go back to 8080 for now. 

Which also makes me wonder since I thought the following lines:

<Connector port="8080" protocol="HTTP/1.1"
               connectionTimeout="20000"
               redirectPort="8448" />

Wouldn't it redirect to port 8448 when I go to http://<serverIP>:8080/era/webconsole?

 

Any help appreciated

Thanks

Please raise a support ticket for help with troubleshooting the issue.

I was about to ping your support personnel; but I think I solved this issue.

The problem was indeed the firewall.  Unfortunately, not being familiar with CentOS7, I had thought it was using iptables; but it was actually using firewalld.  

After doing the following command:

firewa

sudo firewall-cmd --zone=public --add-port=8445/tcp

It now works.
