Here is an example of the files in the zip archive:. We will need to combine only two(2) files in the correct order for the site crt file to work with Nginx. Comodo will then email you a compressed ZIP file called something like mydomain_com. In the zip file will be four(4) files.

Updated to FreeBSD 10. Fixed a bug where the CARP VIP status was incorrect when the interface has more than one. Improved OpenVPN server handling. 3-RELEASE-p16 * FreeBSD Security Advisories * FreeBSD-SA-16:29. * Fixed issues when XMLRPC synchronizes IP Alias type Virtual IP addresses.

Preempt allows all CARP interfaces to fail over all at once if any one CARP aliased interface fails or goes down. We are allowing both machines to forward IPv4 and IPv6 packets through both interfaces and enabling CARP preemption. The following settings are the basics needed to get CARP and ip forwarding to work, check out our FreeBSD Tuning and Optimization page for additional FreeBSD 10 network performance tweaks. Both firewalls use the same /etc/sysctl.

I was a long-time OpenBSD user since the OpenBSD 2. 7 days, and cut my teeth on Unix development there. I was attracted by its focus on security and.

9 clients per second per core and complete each certificate signing in 22ms (0. At rsa 4096, like what calomel. Make special note that the first results are for a single core and Nginx can work with multiple cores depending on your “worker_processes” directive. Org is using, openssl specifies this machine can handshake with 44. The “sign” and “sign/s” are the values we want to examine. At rsa 2048 openssl can handle 300. 1 SSL handshakes per second per core and sign in 0.

Enable the “keepalive” directive to allow a remote client to send multiple queries per TCP connections. Take a look at our examples above concerning keepalive_requests and keepalive_timeout. You will want to look at the average amount of objects per page you serve. A keepalive_timeout of 300 seconds is good to support long lived connections and the default 300 second timeout of a negotiated ssl connection. ) then set the keepalive_requests to something like 50 or 5 times the average. If we have 10 objects (pictures, html, css, html, ect. This means a client could load 5 full pages if they did not have local caching enabled before they would need to open another connection. Keepalive_requests 50; keepalive_timeout 300 300;.

You can setup a static route to your internal router. The syntax ordering is important, make sure not to randomize the directives on each line. We have included multiple examples of both IPv4 and IPv6 CARP aliases to show the configuration patterns. The MASTER and BACKUP firewalls will have their own /etc/rc. Look at the section following the configuration files for details about the CARP aliases. The “static_routes” line is included in case you have multiple private subnets on your LAN. Note the “advskew” on the MASTER is zero(0) and on the BACKUP firewall the advskew is 100. The differences are the unique native ip addresses assigned to each interface.

The BACKUP firewalls will not advertise, only the machine which is the current MASTER. Multicast Advertisements: CARP advertisements are multicast to the 224. The watch CARP advertisements use “tcpdump -npi mxge0 -T carp”. 18 for IPv4 or FF02::12 for IPv6 multicast groups. You will see one CARP advertisement packet per vhid from the MASTER firewall.

I am having trouble configuring carp interfaces in FreeBSD 10. Ifconfig_em1_alias0=”vhid 11 advskew 210 pass PASSWORD alias 192. CARP changes in FreeBSD 10.

We suggest a password of 30 characters which is the maximum length allowed. CARP uses a cryptographically strong SHA-1 HMAC to protect each advertisement. Is the authentication password used when talking to other CARP enabled hosts in the same redundancy group. The “pass” string for each CARP alias must be the same value on the master and the slave firewalls. The “pass” strings do not have to be all unique like in our example above, but for security we generated a unique string for each and every CARP alias.

The certificate authorities’ site should tell you the methods allowed. For Comodo, they prefer we copy and paste the CSR into a text box on their web page and hit submit. Csr file or copy and paste the contents of the CSR file into the website. Csr file and make sure to include the “BEGIN CERTIFICATE REQUEST” and “END CERTIFICATE REQUEST” lines.

Truthfully, this would be doable with most home DSL, Cable or FIOS connections. You need to make sure your upload bandwidth can handle the site you are trying to serve. If you want to serve that same page to 10 people per second then you will need 10x the bandwidth or 4 megabytes per second. Lets say you have a main web page and it contains 10 objects,(i. If you want to serve one person per second then you will need at least 400 KB/sec of upload bandwidth including the TCP stack over head. Pictures, text, css and so on) and the total size of all the objects are 300 kilobytes. 300 KB by the way is the average size of web page these days according to Google.

  1. Add to the fact that we might soon be hitting 25k of unique visitors, we might need to look for a new host. We are basically running 90 odd plugins at all times, and this causes 502 errors when we try updating the site. Which host are you on. We’re pleased with WPEngine, but been getting 502 timeouts due to the amount of WooCommerce extensions we have.
